24V DC Cooling Fan feature uses

1, "24V DC Cooling Fan" in the use of: cooling fan is mainly to solve the heat problem computers, electrical appliances, machinery, power supply, reduce equipment operating temperature, extend equipment life. There are some devices use the fan wind, air pressure to the complete functionality of the device, such as air pressure tables is to use the fan so that the ball can drift in the ball surface.
2, "24V DC Cooling Fan" extremely kind of 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 stator and rotor of two parts, the stator there poles (winding or permanent magnet), the rotor winding energized, the rotor has a magnetic field (magnetic), there is an angle between the stator and rotor poles, "24V DC Cooling Fan" in the rotor magnetic field (N and S poles between) the operation of the work under mutual attraction.
