Abstract
Disclosed is a cooling fan capable of eliminating noise interference, comprising a shell, a stator unit, a circuit board, a guide connector, a fan wheel and a magnet ring. The stator unit comprises an upper insulating frame located on the axle tube in the shell, a lower insulating frame located on the axle tube and under the upper insulating frame, a plural layers of silicon steel sheets sandwiched between the upper insulating frame and the lower insulating frame, and a coil winding between the upper insulating frame and the lower insulating frame. The circuit board is located on the axle tube and comprises at least one ground point. The guide connector is connected with the ground point and at least one silicon steel sheet. The fan wheel comprises a hub, a rotary shaft connected with the hub and rotatably penetrated inside the rotary shaft, and a plurality of blades extending from the outer side of the hub. The magnet ring is located at the inner side of the hub of the fan wheel. Thereby, it can effectively eliminate the noise and the interference.
