Information
The DC fan is converted into a machine by the DC voltage and electromagnetic induction, which drives the blades to rotate. Therefore, the fan casing and the blades are indispensable as a whole. Most people know that these two parts are important, then they are What kind of role does it have?
First, the blade curvature: within a certain range, the greater the curvature of the blade, the greater the gas kinetic energy at the same speed, that is, the greater the air volume and wind pressure; at the same time, the greater the resistance of the blade, the torque of the motor is required. Bigger.
Second, the diameter of the motor: Due to the existence of the motor and the bearing, the central part of the DC fan spindle is inevitably a blind zone with no airflow, and the diameter of the spindle determines the size of the blind zone. The diameter of the main shaft depends mainly on the power of the fan motor. High-power motors require larger stator winding coils, which inevitably take up more space. In the case of inability to expand vertically (increase the height), they have to expand horizontally ( Increase the area).
Third, the blade curvature: in addition to having a certain curvature in the cross section, the fan blade does not extend straight in the radial direction in the plan view plane, but is slightly curved toward the direction of rotation, and has a certain curvature. If the blade extends straight in the radial direction, the airflow driven by the rotation of the cooling fan will be scattered on the side of the air outlet, the air supply distance is short, and the “strength” is not concentrated; if the current product version is slightly curved, the airflow can be ensured. Focus on the columnar space directly in front of the air outlet to increase the air supply distance and wind pressure.
Fourth, the blade spacing: the distance between the blades is too small, which will cause airflow disturbance, increase the friction of the blade surface, and reduce the fan efficiency; if the distance between the blades is too large, the pressure loss will increase and the wind pressure will be insufficient.
