How can ultra-thin micro cooling fans ensure long-term operation and ultra-quiet

Many of our products that require cooling fans can only choose thinner cooling fans, especially some household electrical appliances and electronic products, which require cooling fans to not become louder after long-term use. This is difficult for many factories to do. The better one is Japan's Panasonic hydraulic bearing, which has long life and low noise, but the price is high, while domestic oil-impregnated bearings and hydraulic bearings are cheap, but with the increase of time, the reduction of lubricating oil is easy The sound of the bearing touching the shaft core appears. Of course, some domestic cooling fan manufacturers that do better, require special specifications customized by the bearing and shaft core manufacturers, the effect will be better, but it is difficult to guarantee that each cooling fan will be used for a long time. There will be no similar problems. What is certain is that the defective rate is definitely low. Many cooling fan manufacturers can produce fans with double ball bearings for 7mm thick miniature fans, which can ensure that there will be no abnormal noise in 5 years, and the quality is stable. , The quality of the double ball bearing structure has actually been recognized in many industries, but many manufacturers of such ultra-thin cooling fans cannot do it. They can only do it with oil, which has caused the noise problem and has been unable to solve it. Welcome to the heat dissipation classroom and news center of the cooling fan manufacturer again.
