The cooling fan is subjected to the magnetic action of AC voltage and current, and converts the electromagnetic energy into mechanical devices to drive the fan blades to rotate.Therefore, the casing and blade of centrifugal fan are indispensable as a whole.Most people know that these two parts are very important, so what do they do with each other?Blade refractive index: in a certain range of Ryanup cooling fans, the greater the blade refractive index, the greater the steam mechanical energy under the same speed ratio, that is, the greater the exhaust volume and pressure.
In addition, the greater the frictional resistance of the blade, the greater the torque of the motor is required.Motor Diameter: Due to the existence of the motor and rolling bearings, the management center of the main shaft bearing of the cooling fan of Ruianp inevitably becomes a blind area 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 - the motor with higher power requires a larger motor stator winding electromagnetic coil.
It inevitably takes up a lot of interior space.If you cannot expand vertically (plus the aspect ratio), you can only expand horizontally (to expand the total area).Blade Angle: Except for the inevitable refractive index of the Riamp fan blade cross section, in the bird's eye view the blade does not expand vertically along the axis, but is slightly twisted in the direction of rotation to show a certain inclination.
If the blades are widened vertically along the axis, the cyclone, rotated by the DC fan, will be transparent on the vent side, with short exhaust intervals and no concentration of "force";If the current standard commercial version is somewhat tilted, this ensures that the air cyclone is concentrated in a cylindrical interior space directly in front of the vents, plus exhaust spacing and air pressure.Blade spacing: if the spacing between the blades is too small, it will cause cyclone oscillation, blade surface friction will reduce the efficiency of the fan.
