Understand the working principle of the cooling fan
Ruiapple electronic cooling fan is subjected to the magnetic action of alternating voltage and current, and converts electromagnetic energy into mechanical equipment to drive the fan blades to rotate. Therefore, the casing and blades of the centrifugal fan are indispensable as a whole. Most people know that these two parts are very important, so what is the role between them? Blade refractive index: In a certain range of Ruianpu electronic cooling fans, the greater the blade refractive index, the greater the steam mechanical energy at the same speed ratio, that is, the greater the exhaust volume and air pressure.
 
In addition, the greater the frictional resistance of the blades, the greater the torque required for the motor. Motor diameter: Due to the existence of the motor and the rolling bearing, the management center of the main shaft bearing of the Ruianpu electronic cooling fan inevitably becomes a blind spot that the cyclone separator will not encounter. The diameter of the spindle bearing determines the size of the blind spot. The size of the spindle bearing diameter is the key to the output power of the electric fan motor-a higher power motor requires a larger motor stator winding solenoid.
It will inevitably take up a lot of indoor space. If it cannot be expanded vertically (plus aspect ratio), it can only be expanded horizontally (to expand the total area). Blade inclination: In addition to the inevitable refractive index of the cross-section of Ruianpu's cooling fan blade, in the bird's-eye view, the blade does not extend vertically along the axis, but slightly twists in the direction of rotation, showing a certain inclination angle.
 
If the blades are widened vertically along the axis, the cyclone separator driven by the rotation of the DC fan will be transparent on the side of the vent, the exhaust interval is short, and the "force" is not concentrated; if the current standard commercial version is a bit inclined, It can ensure that the blowing cyclone is concentrated in the cylindrical indoor space directly in front of the vent, plus the exhaust interval and air pressure. Blade pitch: If the pitch between the blades is too small, it will cause cyclone oscillation, and the friction on the blade surface will reduce the high efficiency of the electric fan.
 
I believe that after the above introduction, everyone has an understanding of the operating principle of Ruiapple electronic cooling fan. If you have any questions, please consult Ruiapple.
