• Noise handling rules for cooling fans

    The cooling fan speed refers to the number of times the fan blades rotate per minute, and the unit is rpm. The fan speed is determined by the number of turns of the coil in the motor, the working voltage, the number of fan blades, the inclination, the height, the diameter and the bearing system. ...

  • The classification, principle and performance of cooling fans

    Cooling fans are usually divided into the following three categories: 1 Axial flow type: The direction of the air outlet is the same as that of the axis. 2 Centrifugal: Use centrifugal force to throw the air flow outward along the blades. 3 Mixed flow type: has the above two airflow methods. Prin...
