Tiny Cooling Fan principle of the wind

Next summer hot environment, "Tiny Cooling Fan" seem important to you, air dry / wet bulb temperature vary greatly, so in this case the cooling effect is relatively high. Fresh outdoor air through evaporative cooling air conditioner filter, and after a steady stream into the room, and with indoor air, dust, high temperature air from the outdoors muddy, so that the indoor temperature is reduced, the oxygen content of the air and quality are relatively stable. Therefore, the dual function of evaporative air cooling and ventilation effects, thereby creating a clean and comfortable living and working environment. "Tiny Cooling Fan" in the current alternating current, major works by energizing force in a magnetic field coil rotates. Electrical energy into mechanical energy, rotating blades, and because the coil resistance, will produce some heat, it is generally used for a long fans will be hot surface. "Tiny Cooling Fan" principle is very simple, usually on the junior high school physics course will learn.
