The working principle of 12 inch office table fan

The main component of the electric fan is: AC motor. Its working principle is: the energized coil rotates under force in a magnetic field. The energy conversion form is: electrical energy is mainly converted into mechanical energy, and at the same time, due to the resistance of the coil, it is inevitable that a part of the electrical energy will be converted into internal energy.
   When the electric fan is working (assuming that there is no heat transfer between the room and the outside world), the indoor temperature will not decrease, but will increase. Let's analyze the reasons for the temperature rise together: When the electric fan is working, because there is current flowing through the coil of the electric fan, the wire has resistance, so it will inevitably generate heat and release heat outward, so the temperature will rise. But why do people feel cool? Because there is a lot of sweat on the body surface of the human body, when the electric fan works, the indoor air will flow, so it can promote the rapid evaporation of sweat, combined with "evaporation needs to absorb a lot of heat", people will feel cool.
