Zhejiang XingChang Fan Co., Ltd Specializes in the production of cooling fans, micro cooling fans, DC and AC fans. The following technical personnel from our company will explain the design principle of the micro heat dissipation fan for everyone:

The fan impellers of micro heat dissipation fans are carefully calculated, intentionally making the distance between fan blades appear out of order, presenting a "non-equidistant" situation: why is it not equidistant like the DC fan blades?

This is because the sound frequency produced by the rotating wind wheel and the air is "irregular" and becomes a "piece" of wind, not just a sound on a certain sound frequency. Noise is mainly divided into narrow-band noise and wide-band noise, because the narrow-band noise is extremely noticeable and arouses people's disgust. However, broadband noise is softer, so it sounds more pleasing to the ear. Although it cannot be eliminated, it is relatively "resistant" and makes people less upset.

The impellers of micro heat dissipation fans have been dynamically balanced: just as the wheels of automobiles need to be dynamically balanced, the wind wheels of heat dissipation fans also need to do this work. In short, it is to keep the balance of the wind wheels in the running state, reduce noise and prolong the service life of the fans.
