Accessories are very important for cooling fans. Although water cooling and liquid cooling are very effective ways of heat dissipation, air cooling is the cheapest one. But compared with the water-cooled radiator, the biggest problem of air-cooled radiator is the noise produced by the fan when it works. Of course, there are many factors that determine the noise level of the fan, including speed, size, dynamic balance, operating environment and so on. One of the most important factors is the type of bearing of the fan.
When you know something about these bearings, you will know why some fans cost 10 yuan, while some cost hundreds or even hundreds of yuan. In addition, it can also provide valuable reference for you when purchasing CPU fans or chassis fans. As a leading motor cooling fan supplier in China, WHEE hopes this article can be helpful for you when purchasing fans.
As the important cooling fan accessories, we all know what bearing is. In mechanical engineering, there are many types of bearings, but in fact, there are only a few types that can be used in radiator fan and chassis fan: sleeve bearing with sliding friction (oil bearing) and ball bearing with rolling friction and hybrid bearings of above two kinds of ones.
In recent years, major radiator manufacturers have introduced new technologies in bearing, such as maglev bearing, water wave bearing, magnetic core bearing, rifle bearing and so on.
We, DONGGUAN WANHANG ELECTRONICS TECHNOLOGY CO LTD will provide you with professional guidance on how to select the bearing as a key accessory of cooling fan. If you have any questions, please call us.
