In fact, the so-called centrifugal fan is just one form of fan. The reason why it can increase such a large power is largely due to the impeller of the fan.
The so-called impeller refers to the blades of the fan that we often see. Many people believe that the high efficiency of a fan is due to its relatively fast speed. Yes, the improvement of fan efficiency is directly related to the fan speed.
However, impellers are a relatively energy-saving measure that can ensure the use of the same power while improving efficiency.
Impeller can improve the working efficiency of centrifugal fans. One is the diameter of the impeller, and the other is the inclination angle of the impeller.
If the diameter of the impeller is relatively large, it means that the model of the centrifugal fan is large enough.
So the power will be effectively increased, which is also the reason why all high-power fans are relatively large.
The other is the inclination angle of the impeller of the centrifugal fan. If the inclination angle is small, the power will be low.
On the contrary, if the inclination angle is large, the power of the centrifugal fan will increase. However, this is also within a certain range, as the inclination angle of the impeller cannot reach 90 degrees, mostly within sharp angles. Otherwise, the lifespan of the centrifugal fan impeller will be shorter.
