After some cooling fans are installed, they are not fixed, but in a state of being constantly vibrated. Does this have any impact on the cooling fans? There must be some, especially high-intensity vibration, which may damage the original structure of the cooling fan.
The assembly of the cooling fan is a tightly matched structure. For example, the motor shell and the magnetic stripe, the motor shell and the fan blade, the bearing and the outer frame tube, the stator and the outer frame tube, etc. are all a clamping structure with tightness. The requirements are too much, too loose, and the height of each dimension is strictly controlled. If it is subjected to high-intensity vibration, these precision dimensions may change, or become a little noisy, and the emphasis will not change.
Therefore, during the production process, the cooling fan accidentally landed, requiring re-testing before packaging. just in case.
