Can the axial flow type 3007 cooling fan be quiet?

There are many products that require small and thin axial-flow cooling fans, such as 2006, 2507, 3007, 4007, etc. These miniature ultra-thin cooling fans with a thickness of less than 10mm, 3007 cooling fans are often heard from customers It is said that there is a noise problem. With the increase of time, there are more and more noise problems. Is there any way to solve it? The best and most effective way is to replace better bearings. At present, most of the 3007 fans made by manufacturers use oil-containing copper bearing fans. This kind of rough bearing has a good sound under the action of lubricating oil and takes a long time. If the oil volume is reduced, the noise will come out. If you use double ball bearings, the sound can be improved. At present, only the Japanese ISC brand can do such thin and small balls. In addition, for the oil-containing 3007 cooling fan For the noise problem, the cooling fan manufacturers have made improvements in the following aspects. First, the 3007 bearing of the special mold is independently developed, which is fully compatible with the bearing mold of this size. This fineness is better than that of the common model of many fans. a lot of. Second, the principle is the same when opening a special mold axis. Third, the fan blade balance coefficient is made smaller, so that the balance is better, and the cooling fan is more balanced when running. Fourth, the hydraulic structure is adopted to make the lubricating oil less volatile and prolong the silent performance. From the above three aspects, the mute effect of the cooling fan can be effectively extended to more than 1 year, but the cost will be about 0.8 yuan higher than the ordinary one. For customers who require mute, you can consider this mold. Welcome to the heat dissipation classroom and news center of the cooling fan manufacturer again.
