Information

Due to the particularity of DC cooling fan products, the industry standard is: for the cooling fan with outer frame, according to the size of the cooling fan, the single body falls to 30-100cm, six sides, freely falls on the 1cm thick board, the cooling fan is partially damaged, but the cooling fan can operate normally, and the electrical performance is qualified.

It seems that the landing standard is not high. The main reason is that the internal structure of the cooling fan is closely matched. For example, the bearing heel tube, the stator heel tube, as well as the motor shell and the fan blade are all tightly matched structures, which are not integrated

When the landing height exceeds the standard, when the landing is impacted, the structural dimension changes, which will cause the cooling fan to make abnormal noise, and it will not rotate if it is stuck

Over standard height landing, for the commonly used frame leaves, the plastic material is PBT material, medium pipe, rib, fan leaf, which is easy to vibrate and break, causing the cooling fan may not work. For the double ball type fan, the PC material can withstand the landing requirements of higher standards.
