Attention Problems in Installation of Cooling Fan
There may be many people do not know what should be paid attention to when installing heat cooling fans. We should pay attention to the following ways, otherwise the service life of heat dissipation fans will be shortened.
1. Inverted clothing, fan blade downward, long-term use if the fan blade hangs for a long time, the rotor magnetic weakening, the fan blade from the motor stator distance, heat dissipation fan may not rotate due to poor induction, oil-bearing fan is the most prone to such problems, need to do some structural design processing.
2. Holding the two sides of the fan or plugging a screw diagonally into the screw hole of the fan, these two ways of heat dissipation are easy to cause the resonance between the fan and the product, amplify the sound, and the severe vibration of the fan for a long time will affect the friction between the bearing and the shaft core, and reduce the life of the fan.
3. The life of exhaust heat dissipation is shorter than that of blow heat dissipation, because the exhaust heat is always hot air, the motor is often in the state of heat absorption, heating the driving IC in the motor, making the performance worse.
