Floor test standards for DC cooling fans

by:TOCH     2021-03-26
Due to the particularity of its products, the industry standard is: for a cooling fan with an outer frame, according to the size of the cooling fan, a single floor of 30-100cm, six sides, freely falling on a 1cm thick wooden board, heat dissipation The fan is partially damaged, but the cooling fan can operate normally, and the electrical performance is considered qualified. It seems that the standard for landing is not high. The main reason is that the internal structure of the cooling fan is tightly matched, such as the bearing and the middle tube, and the stator and The middle tube, motor housing and fan blades are all a tightly matched structure. They are not an integrally formed floor that exceeds the height of the standard. When the floor is impacted, the structural size changes, which will cause the cooling fan to produce abnormal noises and freeze. The floor height exceeds the standard. For the commonly used frame blades, the plastic material is made of PBT material. The middle tube, ribs, and fan blades are easy to break and cause the cooling fan to fail to operate. For double-ball type fans, changing to PC material can withstand higher standards of landing requirements.
