The performance of the cooling fan is determined by the bearing, air volume, wind pressure and other parameters. What factors will affect the quality of the cooling fan and how to distinguish the performance?


1. The bearings commonly used in cooling fan include oil-bearing and double ball bearing. The price of oil-bearing will be cheaper. The double ball bearing has higher performance and longer service life than oil-bearing.


2. Some people think that the larger the fan, the better the heat dissipation performance? The advantage of large fan depends on the length of the fan blade, heat dissipation area, so the total air flow is large. The heat dissipation capacity of large fan is not as good as that of small fan. Finally, the parameters of the same fan are the same. If the leaf is changed from five to seven, how much is the change of air flow, and the speed ratio of seven blades will be less than five, so choose seven fans relatively Blade cooling fan, double ball bearing damage, less oil leakage, fan service life is relatively long, the thicker the blade of the cooling fan, the larger the leaf tilt angle, the greater the air pressure, the fan blade inlet angle is one of the key to determine the cooling fan air volume.


The above is a brief introduction to the temperature resistance of DC axial flow fans. I hope it can help you. Shenzhen dongxingyue Technology Co., Ltd. specializes in producing DC fans, AC fans, blowers and centrifugal fans. There are a variety of standard models for you to choose from. We have been established for more than 10 years and have done a lot of industry cases to understand the demand of various industries for cooling fans.
