For heat radiation apparatus; Structure of fan rotor magnet,: by the fan blade and shaft; the stator: from silicon steel sheet, coil and a bearing; the control circuit: by IC induction magnet N.S. pole via the circuit controls the coil is conducted while generating inner excitation causes the rotor to rotate.
The electric fan main components are: AC motor. Its working principle is: the electric coil in a magnetic field force. The conversion of energy form is: electric energy is converted into mechanical energy, at the same time as the coil has a resistor, so inevitably there is a part of electric energy to be converted into heat. Rechargeable fans work (assuming the room with no external heat transfer ) indoor temperature is not reduced, it will rise. Let us together to analyze temperature rise reason: electric fan work, due to the current through the coil of wire electric fan, there is resistance, so will inevitably produce heat from heat, the temperature will rise. But why do people feel cool? Because the human body has a lot of sweat, when the fan works, the indoor air can flow together, so we can promote the rapid evaporation of sweat, combined with" evaporation needs to absorb a lot of heat", so people will feel cool.
