"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 energy. "Waterproof Cooling Fan" use of water cooling, usually increases the humidity in the room, if necessary, can be used to reduce the degree of desiccant dehumidifier or room.
