1. Principle: Water absorbs heat when it turns into water vapor. The fan blows the wet curtain in front, and the water on the wet curtain turns into water vapor and cools.
2. The simplest: Dip a wet towel in water and hang it in front of the fan. There are two problems: the contact area between the wind and water curtains is small and the effect is poor; it dries up after a while and becomes ineffective.
3. Experiment: Use wire or strips of wood to create a frame the same width as the fan. Wrap cotton rope or strips of cotton around the frame at regular intervals, leaving gaps for the wind to pass through. .After touching the water, let the wind wet the frame. Blowing through the gaps in the strips increases the contact area with the media and the air is cooled to some extent. Several rows in front of the fanwork better. The problem is still to do it in a certain time.
4. Additionally: Use the above frame to wind the cotton rope or cotton strip vertically, leaving a margin at the lower end, and insert it into the water tank. The water will siphon upward along the cotton rope. or a cotton strip, like an oil lamp, the wick is automatically moistened, essentially formed and ready for use after blowing air. But the height of the siphon is limited.
5. Finished Product: A water pump is used to supply water to the wet curtain. The wet curtain is also a special ventilated porous curtain, plus a skeleton shell switch, air grille indicator light or advanced indicator. show the brand of the protective cover, etc.

I want to use water in small pipes to produce water electricitye. I only need to generate electricity. small amount of electricity of a few watts. Can I do it?
2.2M waterfall, the maximum water height is 2.2M. Take 2M for calculation, and the flow rate is 1L/S. Gravitational potential energy T=mgh, P=mgh/t=1000*10*2=20000J/s=20000/3.6=5.5KW
The efficiency of the original owner's homemade turbine will not exceed not 50% because that’s too small .
The motor efficiency will not exceed 85%
The power is therefore conservatively estimated at around 2 kW.
Since the water level is too low, the poster needs an axial flow vane turbine, and he can make one himself. Next, engage the gearbox at high speed. This can achieve higher efficiency.
Since the power is too low, a 3 kW DC motor can be used with a relatively simple structure, and then an inverter can be added.
Theoretically bylant, it is possible. In the news, I saw a resident making a homemade wind turbine to produce electricity. It can produce ten degrees of electricity per day, and it can also be stored. batteries. But I also have to tell you that this guy spent tens of thousands of dollars tinkering with this thing, and the tension was very unstable at first. I work for the China Three Gorges Corporation and should know something about hydropower. As for the Three Gorges project, it generally takes about four square meters of water to produce one kilowatt hour of electricity. the water height of the Three Gorges Reservoir is? How big is the traffic? If you're using small pipes I can't tell, but you definitely won't be using just square water. If you do it at home, you need to calculate the cost. Additionally, you may have to experience voltage issues related to productionction of electricity. You will also need transformers. The principle of electricity production at the Three Gorges hydroelectric power station is as follows. Water flows through the water turbine, causing the water turbine to rotate. The water turbine then turns the generator rotor above it. The rotor and the magnetic plate outside produce an electromagnetic reaction, thereby generating electricity. This may be a little difficult for you.
