1, "Micro Cooling Fan" in the use of: cooling fan is mainly to solve the heat problem computers, electrical appliances, machinery, power supply, reducing the operating ambient temperature of equipment, extend the life of the equipment. There are some devices utilize a fan of wind, air pressure to the complete functionality of the device, such as air tables is to use the fan pressure on the ball so that the ball can drift countertops.
2, "Micro Cooling Fan" type of extremely works: two main types of cooling fans and DC and AC a) DC cooling fan is to provide the use of a DC power supply: DC motor has two major components of the stator and rotor, stator magnetic poles (winding or permanent magnet), the rotor windings, after the "Micro Cooling Fan" is energized, the rotor is also formed on the magnetic field (magnetic pole), there is an angle between the stator and rotor poles, the rotor magnetic field (N and S poles between) the mutual attraction of the work under the operation.
