Is it better to have as many blades as possible? There are many kinds of cooling fans, each size of cooling fan also has a number of fan blades, there are 5,7,9,11, then these fan blades are not the same what is the difference, what kind of difference will there be, let's find out whether the fan blades of the cooling fan are as many as possible? 

The performance of the Fan Blade is related to many aspects, such as the curvature, curvature and obliquity of the blade. If the curvature of the blade is the same for the fan with the same parameter, the height and width of the fan will be affected to a certain extent, the wider the blade width is the higher the height, the narrower the blade height is smaller, then there will be fan performance problems.

 By comparison, we find that the blade spacing of narrow fans will increase, leading to the dispersion of air flow, the dispersion of air flow will reduce the performance of fans, then how to solve this problem? The more blades you add, the less space between the blades, the more concentrated the air flow, the better the performance of the fan, and some manufacturers will design cooling fans, if the blade spacing is too large, will increase the number of fans to compensate. The increase of the fan blade has an effect on the air volume. Under the same rotating speed, the more the fan blade, the more the air volume will be released. The Fan Blade will divide the air flow into different parts, and the air pressure on the fan blade will be reduced, the air flow on the blade of the friction will be reduced, the duct will be more smooth, the air flow is also more.

 The above is Dongxing Yue Fan Fan Fan Fan Fan fan is the more the better a brief introduction, choose a good fan is very important, not only to make the normal operation of equipment, but also to extend its life, increase working efficiency, if you want to know more about DC cooling fans, please visit our http://www.dxymotors.com。 .
