The 5-leaf type is better.
The five-blade electric fan mainly uses the principle of airplane wings and propellers. Compared with the ordinary three-blade electric fan, it will increase the load and load capacity, providing a wider power range. Wind range and wind power adjustment can also add more speeds and the noise will also be reduced.
In short, the more fan blades there are, the more "wind" can be cut into smaller pieces, making the blown wind smoother and quieter.
The fan has five blades, but most of us use three in daily life. Similarly, there are also four-blade and six-blade fans (three-blade fans have high speed, four-blade fans have low speed, and the wind pressure is different, which is related to the structure of the fan). 'ch exchangeraleur.)
Number of fan blades
p>The number of blades of axial fans is usually an odd number because when correcting the dynamic balance, the odd number of blades is easier. to correct the center of rotation. If an even number of fan blades are used, it is easy for the system to resonate. If the blade material cannot withstand the fatigue caused by vibration, the blade or bearing will break easily. Therefore, an odd number of fan blades will be used. asymmetrical axes are more suitable.
