Demystify! Why the number of fan blades is increasing

The performance of a cooling fan is closely related to its parameters, but the number of fan blades also affects the cooling performance of the fan. If you pay attention to cooling fans, it is not difficult to find that there are more and more fan blades on the market. Why? In response to this question, Suzhou Santian Precision Mould Co., Ltd. will answer it for you.

Generally, the electric fans with three, five and seven fan blades currently on the market will have a difference in the area index of the fan blades. The area index of the three fan blades is large, the wind speed experience is strong, and the area index of the seven fan blades is small. , The wind is milder. The bladeless fan of the noise reduction board has the least noticeable wind speed, but the wind direction is higher.

 

Therefore, if you expect to be in a relatively quiet natural environment, such as a bedroom or a small study at home, or a company office, it is recommended to use a larger number of fan blades and a smaller total area. You can also choose a DC motor fan, wind cut noise, module, and motor The running noise is relatively small.

 

In general: the smaller the total number of fan blades of general electric fans, the larger the total area, which means the greater the noise and the stronger the wind speed. On the contrary, the more the total number of fan blades, the smaller the total area, which means less noise and milder wind. If the noise is annoying, it is recommended to choose a DC motor multi-blade fan.
