When our product needs to install a cooling fan to remove heat, it may be affected by factors such as space, environment, shape, etc., resulting in different installation methods. The installation methods often encountered are as follows
1. Stuck on both sides of the cooling fan, or plug a screw at each corner into the screw hole of the cooling fan. These two cooling methods are likely to cause the cooling fan to resonate with the product, amplify the sound, and the fan will vibrate for a long time. Affect the friction between the bearing and the shaft core, and the life will be reduced
2. Install upside down, with the fan blades facing down, and use for a long time. If the fan blades are suspended for a long time and the rotor magnetism becomes weak, the distance between the fan blades and the motor stator becomes less, and the cooling fan may not rotate due to poor induction. The fan contains oil. This type of problem is most likely to occur, and some treatment needs to be done from the structural design
3. The service life of exhaust heat dissipation is shorter than that of blowing heat. Because the exhaust is always hot air, the motor is often in a state of absorbing heat, and the driver IC in the motor is heated, which makes the performance worse.
