What is the difference between a hydraulic cooling fan and an oil-contained cooling fan?
There are many patented bearings for cooling fans. Today we are talking about the hydraulic bearing and the oil-impregnated bearing are two commonly used bearings. The bearings look similar, so what is the difference between them? First of all, as far as we know, the hydraulic bearing is a patented bearing of Panasonic. The sound of this copper shaft is relatively small. It is said that the cooling fan has a long life and the price is very expensive. The material of the hydraulic bearing fan we currently make in China is the same as that of the oil-impregnated bearing. The outer frame adopts an integrated structure, which is very similar to the shape of Panasonic. In fact, the cost is similar to that of the oil-impregnated bearing. The hydraulic bearing is because of the integrated structure. Therefore, it is inconvenient to disassemble and repair. If there are defective products in the process that need to be repaired, it is very inconvenient. In addition, some fans will be scrapped when the product assembly size is adjusted before production. Therefore, hydraulic cooling fans generally require orders in Above 3K. Regarding the performance of the product, the oil-contained cooling fan is not much different from the hydraulic type. Because the bottom of the hydraulic bearing is sealed, it has a stronger temperature resistance and a relatively long life.
