The responsibility of the fan in the air-cooled radiator is: by virtue of its own guiding effect, the air passes through the heat sink at a certain speed and in a certain way, and the heat exchange between the air and the heat sink is used to take away the heat accumulated on it. Realize the "forced convection" heat dissipation method.
From the use of power supply type can be divided into AC and DC two categories.
DC has 5V,12V, 24V and 48V, which are more common. Special ones such as 4.5V,10V, 18V, etc. AC is generally 220V,110V, etc.
The way to switch the magnetic field from the power: it can be divided into two types: brush and brushless.
Brush motor life is short, will produce electric spark.
· Brushless motor without carbon brush wear and long life, easy to run at high speed, no spark. Has gradually replaced the brush motor
From the scope of application: its use is very wide, such as power supply fan, chassis fan, CPU fan, VGA fan, refrigerator fan, car fan and so on.
The composition of the fan is divided into two parts: the rotor and the stator:
Rotor: including fan blade, shaft center, magnetic ring, magnetic ring outer frame and oil ring.
· Stator: including motor, outer frame, bearing, buckle ring, etc.
