"Waterproof Cooling Fan" works
"Waterproof 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 cause of temperature rise: When fans work, due to current through fan coil wire is resistance, it will inevitably produce an exothermic heat outward, so the temperature will rise. But why people will feel cool it? Because the body's surface have a lot of sweat, When fans work together, 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. "Waterproof Cooling Fan" basic structure.
Mainly consists of four parts:
Rotor: the magnet, the blade and the shaft composition;
Stator: from silicon, spools and bearing components;
Control circuit: IC induced by a magnet;
S. pole circuit control via its coil is turned on and generates an internal excitation of the rotor to rotate.
