Removable Micro Cooling Fan

"220V Cooling Fan" The main components are: AC motor. Its working principle is: energized coil in a magnetic field by the force of the rotation. Form of energy is transformed: the main electrical energy into mechanical energy, and because the coil has a resistance, so that there is an inevitable part of the electrical energy to be converted into heat. When the fan work (assuming no heat transfer with the outside room) not only did not reduce the indoor temperature, it will rise. Let us analyze a temperature rise causes: "220V Cooling Fan" work, since the current through fan coil wire is resistance, it will inevitably produce heat outward heat, so the temperature It will rise. But why people will feel cool it? Because the body's surface have a lot of sweat, when after "220V  Cooling Fan" Working together, the indoor air can flow together, so we can promote the rapid evaporation of sweat, combined with "evaporative need to absorb a lot of heat", so people will feel cool.
