Cooling fan and the types and USES
a cooling fan is not exist alone, most of the occasion will be used with heat sink, in use up to have a cooling fan, graphics card cooling fans, auto cooling fan, north ( South) Bridge a cooling fan, chassis cooling fans, hard disk cooling fans, power supply cooling fan, etc. Cooling fan is the basic structure of the general by motor, bearing, door frame, blades, wire and other components of the village, when the motor running stationary part of the stator, the runtime part rotation of the rotor, motor speed means has two kinds of regulating speed regulation and frequency modulation speed control, which is the mainstream of the current application can well realize the fan speed according to the need to control, and temperature control fan through the PCB with a thermistor sensor temperature and speed, the faster the temperature and the higher the speed, but why is singular cooling fan blade? Because want to keep the fan running balance as much as possible to reduce the impact of resonance, singular blades is the best choice. Wenling city tong chi auto air conditioning manufacturing co. , LTD. , specializing in the production of cooling fans.
