How to make a small fan cooler
In the period of abnormal heat, protection from it becomes a big problem. On how to quickly cool the air in an apartment, room or house, what to do without air conditioning RIA Novosti, 12.07.2021
MOSCOW, July 12. RIA Novosti. During the abnormal heat wave, protection against it becomes a big problem. This RIA Novosti article discusses how to cool the air in an apartment, a room or a house quickly, what to do without air conditioning or a fan and unusual tips to reduce the temperature indoors. How to cool the room in the heatThis year in many regions of Russia established an abnormal heat, up to 35 degrees. Many people feel unwell at such temperatures, they are fraught with heatstroke. To make things worse, the fact that panel houses, of which there are now more than brick ones, heat up much faster. And if your apartment has low ceilings, few windows and small rooms the heat is even worse. And when an apartment is on the top floor, under a red-hot roof, and there is no technical room above, the heat is unbearable. But if you don’t have air conditioning or a fan, there are several other effective ways to cool rooms.Close the lightThe fastest and easiest way is to close off the light in the room. To do this, simply close the windows or lower the blinds even in cloudy weather. The temperature can drop a few degrees.Curtains and blindsThermal (infrared) radiation enters the room not only as direct sunlight, but also as scattered radiation through clouds. In order to reflect this radiation, curtains must be thick and light-colored to repel light better. They should be kept closed in the morning and in the afternoon, and open at night. At the same time, fabric or iron blinds are much more effective at this task and retain up to 90% of the light. In general, shading not only protects the apartment from sunlight, but also prevents the heating of electrical appliances, carpets, etc.д., That is, things that also raise the temperature of the air. You need to shut the windows from 8 a.m. or earlier.A good way to cool the room in hot weather is to tape the windows with a special light-reflecting film. When buying it, you should consider the light permeability, the level of reflection of infrared radiation. This will depend on how much light will enter the room, including in winter, because the film usually stays on the windows, and in the cold period is not very good, if the sunlight does not warm up the apartment at all. The better the film reflects solar radiation, the cooler it will be. Using foilFoil also protects the room well from high temperatures. To do this, you need to buy a roll of 5 or 6 meters and glue the entire window from the inside. Especially this method is useful if the windows overlook the south side, where the heat is always felt more intensely. The only disadvantage of foil. an aesthetic component, but you can always blind the windows and reflective material will not be visible.Airing a roomGood and regular airing of the room also helps prevent excessive heat. It should be done at certain hours at night and in the morning. A draught in the apartment increases the risk of illness, so it is better not to arrange it. Ventilate the apartment during the daytimeIt is a mistake to air the apartment during the day because heat comes in from outside and the cool air goes out in the open air. Because of this during the day, especially from 12 to 4 p.m., when the sun is most active, the windows should be kept closed and curtained. At night the coldest temperature is between 4 and 7 a.m., and this is when you should open the windows. In order not to get up so early, you can do it before going to bed and close them before 8 a.m. If it is warmer outside than in your apartment you do not need to ventilate. Systematic humidification of the apartmentIf you add to the above methods humidification of the room, you can significantly reduce the temperature in the apartment or house. Not only a wet mopping, but also the use of ice, wet sheets, etc. will do the trick.д.Wet CleaningTo cool the room and reduce the dryness of the air, it is important to wash the floor and all surfaces with cold water as often as possible. Carpet should be removed from the floor because it strongly attracts heat and is a good insulator. Also during the day humidify the air with a spray gun or a special electronic humidifier. Using Wet SheetsSome people recommend using wet sheets in the heat, like throwing a blanket over or on the bed, but it is dangerous to your health. According to doctors’ reviews, a person can develop kidney disease or pneumonia, and symptoms of a cold, such as fever, weakness, stuffy nose, cough. Because of this, you should not put anything cold on your ears, elbows, wrists, and knees. Wrap a cold towel around your head, but only for a short time. Wet sheets should be used to cover the windows.Using iceBottles of frozen water are a good way to cool the room. There may be more than one bottle, for example 5 to 6 liters will reduce the temperature by at least 3 degrees or more. They should be placed higher up, such as on a cabinet, or in front of a fan to keep the air cooler. Isolate the roomIt is usually cooler in the hallway, so open the door to let the air in to the other rooms. You can also keep the doors to each room closed, with curtains and shuttered windows. This will keep the coolness in. Open them at night, though. Insulating the kitchenThe kitchen is always the hottest because of so many heating appliances, especially during cooking. If you have a gas or electric stove running, turn the cooker hood to maximum or ventilate the room. Also, the air can get hot from the microwave and cooked food, so it’s best to close the door to the kitchen. Cooling the room properly with a fanMany people put the fan so that it is directed toward themselves, but this is not quite right. It’s better that it blows cool air on your furniture, which in turn absorbs the heat of other items in the room. You can put not only ice in front of a fan, but also just bottles of cold water. Interesting waysThere are some unusual ways to cool off in the heat. For example:Other ways and tipsFor maximum protection from the heat, you can use the following ways and tips:
tips to help cool the room without air conditioning
Keep curtains or blinds closed during the sunny day. Light entering the room heats up the internal atmosphere of the dwelling, creating a greenhouse effect.
Tint the windows or cover them with a thin, reflective film, as they often do in southern cities, such as the Crimea. This film is very affordable and will cost you a few dollars per window, depending on the area.
Cool the room in the evening by opening windows on the cooler side if your windows face different sides of the house.
Insulate the room. Just as you need insulation in the winter to keep you cool in the summer. Remember how cool it is in the summer in old wood or earthen houses with thick walls.
Replace incandescent bulbs with ones that are more efficient in terms of less heat emission, i.e. fluorescent bulbs or even better. LED. Modern light sources generate up to 80 percent less heat than conventional incandescent light bulbs.
If you have a ceiling fan in your home, you should use it to cool the room. Modern fans have a switch that allows you to change the direction of its rotation, changing the direction of airflow. In winter warm air goes downward, in summer the cooler air goes upward.
Drink beverages with ice in very moderation. Nothing original, but it is another way to cool your body, but not from the outside, but from the inside. Drink in small portions to avoid hypothermia of the throat and excessive sweating. Although there is an opinion that it is much more effective to drink hot tea, which stimulates the body to cool itself. The same goes for hot and cold showers. Try it yourself, it is very individual.
Appropriate clothing can help make the heat easier to bear. The best solution is to wear loose-fitting clothes made of natural light fabrics, the leaders in this respect are cotton products.
A wet towel wrapped around your neck or head can help weather the hottest part of the day. Many people recommend the use of wet shoes. If that’s not aesthetic enough for you, use wet wristbands.
Minimize the use of the stove and oven. A natural response to heat is a decreased appetite, so limit yourself to cold snacks and salads during the heat of the day.
Specialists recommend a pillow filled with buckwheat groats if the heat keeps you awake. A pillow filled with buckwheat does not retain heat like a pillow.
Learn from your pets who are sedentary in the heat. If you can, it is better to spend the hottest part of the day lying horizontal. Proceed slowly, measured and without haste.
Cool the room with a fan pointed at something cold: a special ice pack or a normal plastic bottle with ice.
Plant a tree on the sunny side of your home. A tree is the best defense against the midday heat. Do not forget to keep the necessary distance between the trees and the house.
If your car does not have air conditioning or you do not want to use it, put a bag of plastic bottles filled with ice in the backseat. They say it makes traveling a lot easier.
Close the doors in the entryway of apartment buildings. The air at the base of the building is always cooler, because the ground temperature is always lower than the atmospheric air temperature at the surface of the heated ground.
If you can work from home, then it makes sense to switch to a night schedule: sleep during the day, work at night. I have several acquaintances who use this method. The nighttime has the added benefit of fewer distractions.
Painting the walls and roof white is a good idea. This drastic measure works well for hot regions.
Turn off all unnecessary appliances. Better optimize the power consumption of those that are needed. For example, laptops are cooler than desktops, LCD TVs are better than CRTs, and so on. As a rule, the less power consumed by an electric appliance, the less heat it generates.
Adapt. People have been living on this planet for millions of years and during this time they have managed to find their home at all latitudes of our planet, but they have got to know the “joy” of air conditioning just recently and in most cases they can do without it. Keep yourself in good physical shape and you will feel better, both in winter cold and in summer heat.
Myths about computer cooling
Hi Picaboo! Not everyone remembers the days when processors and graphic cards required, at worst, a simple heatsink, and nobody ever heard of case fans and water-cooling systems. But everything has changed: modern processors and graphics cards can consume hundreds of watts under load, so no one will be surprised by three-section air coolers, kilogram supercoolers and a couple or three case spinners anymore. However, with the progress in PC cooling myths have also progressed, and today we’ll talk about them.
As always. The text version below the video.
Myth The more powerful the cooling, the cooler the processor will be.
It would seem that everything is correct: cooler cooling is able to remove more heat from the processor cover, so its final temperature will be lower. But the key point here is the lid, not the chip. And there is a layer of thermite between them, and often the chip itself is quite thick.
What it leads to? After a certain amount of heat generated by the processor it makes no difference what you use to cool it: it all comes down to the sometimes poor quality thermal interface under the lid. You don’t have to go far to find examples: Core i7-8700K scalping and replacing the thermo under the lid with liquid metal will reduce the temperature under load by at least ten degrees. What’s more. the additional grinding of the top-of-the-line Core i9-9900K chip is also capable of removing a couple of degrees.
As a result, for any processor there is a reasonable heat output, and if it is exceeded, no matter how cool the cooling system is, it will still overheat. So it makes no sense to put a three-section water cooling system to the same Core i7-8700K, so that it runs stably at 5GHz. you’ll achieve even better effect with a simple “turret” if you slip it.
Myth The cooler should be chosen according to the TDP of the processor
Many cooler and cooler manufacturers write in the specification of their products how many watts of heat it can dissipate. Similarly, Intel and AMD write the heat dissipation of their processors. So it may seem that if the second figure is less than the first one, then such cooling will suit you.
Alas. there are two misconceptions. Firstly, real heat dissipation of processors under load and overclocking is often much higher than manufacturer’s description. For example Ryzen 9 3900X has nominal heat capacity of 105W, but in fact it can consume almost twice as much, about 180-200W. And if a hundred watts even not the biggest towers can do it, then 200 watts requires super coolers or rather advanced air coolers.
Intel also takes as TDP value the power consumption at base frequency.
How to make air conditioner at home using Plastic Bottle. Easy life hacks
Secondly, the meaning of “a cooler can dissipate X amount of heat” is not always clear. From which processor? For example, the area of the lid of a 16 core Threadripper is almost twice as big as that of a 16 core Ryzen, so it is easier to dissipate heat from it. Plus it is not clear with what thermal paste the cooler will be able to remove the specified number of watts, and there are a lot of such “buts”. By the way, that’s why Noctua, does not specify how many watts their solutions can deliver.
How do you know if a certain cooler will fit you or not?? The answer is simple. read his reviews and see on what test systems it checks, then make logical conclusions: for example, if the cooler coped with the Core i7-8700K, then with a simpler Core i5-8600K will not be problems. And on the other hand, if Ryzen 7 3800X has problems with the cooler, then taking it to pair with Ryzen 9 is definitely not worth it.
Myth Gaming PCs require a HBO.
What a fancy gaming computer looks like? Right, a lot of fans with RGB lighting and of course water cooling system. But in fact for the overwhelming majority of PC’s it simply isn’t necessary.
Why? Firstly, games are loading a processor much weaker than stress-tests, and even top-of-the-line Core i9-9900K able to consume more than 250 W in AIDA64 test, in games and will not reach a hundred, and with such heat dissipation even not the most expensive tower will cope. Secondly, coolers are much less reliable than fans: often in a couple of years the pumps get clogged and begin to work worse and noisier, or even stop altogether. And their cleaning, if it is possible, is not the easiest process. Thirdly and thirdly the efficiency per watt of heat dissipated is poor: if for 4-5 thousand you can buy an excellent super cooler that will easily handle top-end 8-core CPUs, among water-sinks for such money there will only be rather budget and not the best quality models.
As a result. leave the coolers for workstations, where monster processors with a couple or three dozen cores and heat dissipation of about three hundred watts are working. If you are building a system on a home socket LGA1151 or AM4 there is no sense to overpay for a water shield.
Myth Box Coolers are totally inefficient and must be replaced.
In general most users have a bad impression of box coolers: they are said to be inefficient and can not cope with the processors they come with. But in fact it is not so.
Of course, a small aluminum radiator with a bit of copper cannot handle a overclocked Core i9. But, for example, a stock cooler can keep a 6-core Core i5-8400 at 60-75 degrees Celsius in games. and that at critical temperatures of about a hundred degrees. The situation is even better with boxed coolers for Ryzen, of which there are as many as three versions.
Consider the size of your room
Don’t make the same mistake millions of fan buyers have made-don’t look at the wattage before you’ve estimated your living space.
Need to choose a fan based on the size of the room in which you intend to use it. You should agree that it makes no sense to buy a super-powerful device for a small room? You are more likely to be uncomfortable with it. It is possible to judge that a weak device is useless in a large room, in which case you are better off splurging on a more powerful device. Do not forget about the fact that cheap fans are usually flimsy. during operation, they produce a lot of extraneous noise.
If you’re sitting there thinking, “How could I possibly be bothered with a big, powerful fan in a small room??”Remember that a powerful device always makes a lot of noise. You are ready for the humming noise right above your ears? I don’t think so. At a large distance it will not be so noticeable.
Built-in silent extractor hood on coolers 120 with their own hands
The cold weather is coming, and since I. a smoker, and on the balcony is getting colder, it was decided to caulk the windows, in order not to freeze, and since the smoke should still get rid of, I decided to make a budget hood.
It was researched a lot of material from the network “Internet”, but all the ideas rested on three pillars: quickly, efficiently, cheaply. With the first two. it was decided to do everything myself, with the third. Google again to help.
So count: I have a balcony 2,24,5 = 10 square meters.м. (2.5 = 25 cubic meters of air space).
For normal convection, in accordance with SNIP 2.08.01-89 for kitchens with 2-burner gas stoves (calculation for 20 cubic meters). not less than 60 cc/h, so I need to create air outflow not less than 35-40 cc/h of air (we’ll count on 80 cc/h, because we need to take into account resistance of air duct and check valve.) So, digging in the network, we find that the exhaust fan with the necessary characteristics costs from 500r (air flow of 80 cubic meters per hour, the noise of 40 dB. very loud, like a hair dryer), it was decided to use Chinese coolers.
Through an acquaintance (as it was faster for me personally, but you can also find and order on alike), were purchased twelve gamemax gmx-wfbk, with an airflow of 46.5 CFM ( 78 cfm/h), and a volume of 24 dB (pretty quiet).Since the generated air pressure at the cooler due to low speed is lower than that of high-speed exhaust fan, physics and mathematics, scientific poke. to help)))So:
Were bought 4 coolers (90 rubles), a pair of 125mm pipes (75 rubles), check valve (50 rubles), sealant. hetiki (100r), and straight hands (priceless). in total 660r.
First we work the coolers to the shape we need.
While working I used my wife’s slagheap machine)))
Coolers are installed as tightly as possible in the pipe, to create the highest possible air pressure.
The gaps between the walls at the end will be sealed with sealant, but in the meantime. just test the airflow we need.
Since I was planning on doing one pipe. air intake, and the second one. With a reactive hood, assemble the finished design with a check valve, and add one cooler at a time, one at a time, until the check valve opens from the air flow to the maximum position. Adding coolers to one system does not increase airflow, but it does raise the pressure. In this case, we will be sure that the system will raise enough pressure, to pump the claimed 78-80 cc of air. The calculation is roughly as follows: Resistance of 1m of pipe. about 15%, and the check valve. about 5%. Since we have 3m ducts, and 1 valve, we need to raise the pressure for nominal operation by 50%, but experience has determined that the air pressure gusts from the street. sharply close the check valve, which leads to a constant popping, which I was not satisfied. It was decided to increase pressure by 200% (in short, 1 additional cooler increases pressure by about 70-75%).
After we became satisfied with the result we assemble jet-flow tube.
We mark the approximate position, and let’s go)
Each cooler is carefully fixed with any sealant (of course without silicone), trying not to smear the inside surface of the case and most importantly. blades.
Right here. because of my clumsiness a slight knocking and vibration appeared. Disassembly, cleaning, and reassembly. the problem was solved.
The first two coolers (closer to the output), installed one after the other, as they will be the most severe load from the counter flow of air from the street.
For other two. installed longitudinal baffles, to reduce turbulence inside the pipe, respectively. to increase pressure.
In the process of disassembly. test each installed cooler for clattering, beating, vibrations, or increased noise.
In the video you can clearly hear the clattering of the sealant covered blades of one of the fans, which needs to be improved. Sounds “like a helicopter” because the wind is blowing right on the microphone.
After eliminating all unnecessary noise. Give the exterior an acceptable look, and pile everything together:
It is not recommended to use electrical appliances that heat up the apartment significantly during the day. These are vacuum cleaners, irons, personal computers, printers and televisions. Pay special attention to the last item. If you’re not watching TV, turn it off, because in addition to the rise in temperature, your energy bills will also rise. If you have an electric towel rail, cover it with foil or use it only as a last resort. Such equipment always heats up the air in any room.
There’s another interesting tip on how to cool a room in the heat without air conditioning. It consists of using several bowls (basins) of water and a sheet. How to cool the room in the heat with these elements? It’s as simple as that. The basin should be placed near the door, and the sheet should be hung so that its ends are in contact with the water.
The fabric gradually absorbs water, thereby cooling the entire room. It is important that the area of the bed sheet be as large as possible. Remember, the wider and longer it is, the faster the evaporation and heat exchange.

Summer heat in the absence of air conditioning can create considerable discomfort. To cool down and feel good without air conditioning, you can use various tricks using water, fans, light clothing, cool drinks and food, psychological techniques and so on. You can also cool your whole house naturally, preventing it from stagnating heat. With the right approach, you can successfully escape the heat while saving money on air conditioning.
Drink water more often. The body will be cooler if its water balance is in order. Try to drink about 230 ml of water every hour. Adding peppermint leaves or orange, lemon or cucumber slices to your water will make it more refreshing. You might also find it easier to drink the water if it gets a slight taste.  X
- You can also use a fan with a humidification function. These gadgets can even be portable and battery-operated, so you can take them with you wherever you go. When your body gets wet and exposed to the air flow, the water evaporates from your skin’s surface, making it feel cooler in no time.  X
Splash cold water on your wrists. Hold your wrists and other areas of your body with large blood vessels under the skin, such as your neck, inner bends of your elbows and knees, for about 10 seconds each in cold water. It will lower your body temperature slightly.  X Source of Information
- Take a cool shower instead of a bath if you like.
- You can also dip your feet into a bucket of cold water. The body mainly radiates heat from the palms of the hands, feet, face, and ears, so cooling any of these places will effectively cool the entire body as well. Shallow children’s pools are also good for cooling the feet of adults.
Go for a swim. Go to a swimming pool, or go to a river, lake, or sea, and unwind. Immersion in water will cool you down in an incredible way. Outdoors, be sure to use sunscreen to prevent sunburn, which can further heat up the body.  X Source of Information
- If you have blinds on your windows, tilt them so you can see the ground instead of the sky when you look through them.
- For even more protection from the sun, use cellular insulating curtains or sunscreening film, which, similar to tinting car windows, will make the window glass darker or more reflective.
- Be sure to get up early in the morning to close all the windows and curtains when the sun starts to heat up the house. In some regions, you may need to do this as early as 5 or 6 a.m.
- To create good air circulation, use a whole combination of fans. Expel hot air outside by putting a powerful exhaust fan near one window and regular fans near the other windows to blow cooler, fresh air in.
- You can also turn on the hood above the stove or open the chimney flap from the fireplace or stove. They will also help to draw heated air out of the house and fill it with cooler evening air.
How to turn ordinary fan into air conditioner
Summer has come, and with it the heat from which sometimes there is no escape. Cold drinks, cool showers and being in the shade, only briefly help to cool down and take a break from the scorching sun. The only one most effective method of escape from the heat at this time of the year is air conditioner. But not everyone can afford to purchase and install it. In such situation wit and hands that grow from shoulders and also some money and time come to help. We suggest you to know how you can make an excellent air conditioner from an ordinary fan!
To make an air conditioner with our own hands, we will need:. fan (any type). copper pipe. transparent PVC tube. plastic clamps. Aquarium submersible pump with capacity of 600-1000l/h. thermal box (Styrofoam box)
In order to turn a usual fan into an air conditioner, you only need to attach a heat exchanger to the grill of the fan, through which the cold water will circulate, and the fan, in turn, the air flow will transfer the cold from the heat exchanger into the room.
As a heat exchanger we will use copper tube 1/4″ (6.35 mm) which is used for air conditioning systems. The length of the tube will depend on the size of your fan and the density of the coil.
Of course the higher density of the coil the faster cooling will be, but do not forget that a very dense coil will obstruct the airflow, so the main thing here is not to overdo it. For a standard floor fan the length of the copper tube for winding the coil is 5-10m.
It is more convenient to fix a copper pipe to the fan grid with the help of plastic clamps, but as an option you can use a thin wire.
Cut off the ends of the clamps so that they don’t spoil the look.
To connect the pump to the heat exchanger you can use a transparent PVC pipe with an inner diameter of 6 mm., for easy connection to the heat exchanger.
It is possible to match the PVC pipe with the diameter of the pump branch pipe, but in this case it will be necessary to wrap the tape on the ends of the heat exchanger and fix it with the metal strips.
As a reservoir for cold water we will use foam plastic box (thermal box) or any other container (barrel, canister), which is desirable to be insulated with foam plastic.
After all tubes are connected, we place the pump and drain hose into the thermo-box. Periodically, to maintain a low temperature, throw pieces of ice, ice batteries or frozen ice packs into the thermo-box.
As you can see, it is not difficult to make an air conditioner with your hands. Of course, self-made air conditioner will be inferior to the factory one, but nevertheless it is a worthy option to fight the heat.
For those to whom this design of air conditioner seems complicated, we propose to consider a variant, more simple air conditioner:
To make the simplest air conditioner, we need:
In the lid of the thermo-box, cut two holes. One aperture for the fan we cut out with the calculation that the fan will not fall through. Cut the second hole to fit the diameter of the elbow. Self knee is needed for the directional distribution of cold air flow around the room.
The principle of operation of the homemade air conditioner is quite simple. Ice is poured into the thermobox and covered with a lid (which has a fan). The flow of air from the fan being cooled by the ice will be coming out through the knee, and distributed throughout the room. The temperature at the outlet of the elbow is below 10 degrees, and will gradually rise as the ice melts. Therefore, it is necessary to periodically drain the melted water and refill the ice.
If you do not have a thermo-box you can use a large plastic container, but in this case the condensate will be formed on the outer walls and will run down on the floor. It is necessary to insulate a plastic container with styrofoam sheet to avoid such cases.
How to install conditioner from a fan
Qualitative and good conditioner is rather expensive, in addition it consumes a lot of electricity. But nowadays it is very difficult to manage without this climatic device, especially during the intolerable summer heat, conditioner is the only salvation. If you have no opportunity to install air conditioner in your apartment yet you can escape from a mad heat by different folk remedies.
For example, you can periodically cool off with a cold shower, or occasionally spray your body and face with cool water from a spray gun. In addition, the windows in the room can be covered with a special film or you can hang them with thick curtains or blinds. However, the leader among all existing folk remedies for fighting the heat is a self-made conditioner. To make a conditioner yourself there are several ways, but the most common of them is an air conditioner made of a fan.
The first way how one can make an air conditioner from the ordinary fan is using the bottles filled with cold water. Such a home-made air conditioner is suitable for cooling rooms that are not large in area. In order to make such climatic device you will need a home-made fan and several plastic bottles (you can also use glass bottles or beer cans).
Fill bottles with very cold water (it is even better to fill them with ice), and place them in a single line with about two centimeters of distance between the bottles. These gaps are necessary for the passage of air flows.
You can also make a homemade air conditioner from a hose and a copper tube. This model of climatic device is more suitable for medium-sized rooms. To make such conditioner you will need a fan and a rather long copper tube (if you can not buy a copper tube, you can use a common rubber hose, also long enough).
Wrap a copper tube (rubber hose) on the protective grate installed on the fan. You need to leave gaps between the coils of the tube for air flows (take care not to have strong kinks). You should end up with something that looks like a radiator.
Connect one end of the copper tube or hose to the faucet and the other end to the sink or bathtub.
