Auto cooling fan 】
Contribute to heat dissipation
Car is very important in our modern life a electronic product, it is used by the electromagnetic heating, electromagnetic heating is to use magnetic field induction motor heating principle, it USES current through the coil magnetic field, when the magnetic field of magnetic force by iron pot department, namely will produce millions of cars, make the tank itself to high fever, and then heating in the pot food.
Electromagnetic work when the electromagnetic wave, is completely shielding layer at the bottom of the coil and absorbed by iron pot on the roof.
The basis of the principle of electromagnetic induction heating of food, alternating current through the tank at the bottom of the coil magnetic field, magnetic field of magnetic field lines across the bottom of the tank, produce cars, make the tank heat quickly, achieve the goal of heating food.
So the use of automobile cooling fans will have slight voice, so it is normal.
