"Tiny Cooling Fan" The main components are: AC motor. Its working principle is: electrical coil in a magnetic field by the force rotates. 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 internal energy. "Tiny Cooling Fan" work (assuming no heat transfer with the outside room) the room temperature is not only not reduced, it will rise. Let us analyze a cause of temperature rise: When fans work, since there is a current "Tiny Cooling Fan" coil wire is resistance, it will inevitably produce an exothermic heat outside, so the temperature will increased.
