As the main part of the cooling fan, the fan blades, the change of its parameters will affect the performance of the fan. The following content is provided by Suzhou Santian Precision Mould Co., Ltd.:
1. Blade curvature: within a certain range, the greater the blade curvature, the greater the air volume and pressure at the same speed, and at the same time, the greater the resistance of the blade.
2. Blade smoothness: the blade surface is not smooth and flat, it will generate turbulence during rotation, increase friction and noise, reduce fan efficiency, and damage fan performance.
3. Blade spacing: If the blade spacing is too small, it will cause airflow disturbance, increase the blade surface friction, and reduce the efficiency of the fan; if the blade spacing is too large, it will cause insufficient wind pressure and also reduce fan performance.
4. Blade inclination angle: the greater the inclination angle, the greater the pressure difference between the upper and lower surfaces of the blades, and the greater the wind pressure at the same speed; when the wind pressure is too large, it will produce a backflow phenomenon, reducing the performance of the fan, so the blade inclination angle adjustment It should also be controlled within a certain range.
5. Blade tip clearance: If the clearance is too small, the airflow will rub against the blades and the outer frame, increasing noise; if the clearance is too large, the fan efficiency will be reduced due to the flyback airflow.
