1.a heat dissipation fan for ball bearings, comprising a frame, fan blade ball bearings and a motor, wherein a copper pipe is arranged in the center of the bottom of the frame, a stator is arranged outside the copper pipe, fan blades are arranged on the top edge of the copper pipe, an internal thread is arranged on the bottom edge of the copper pipe, a buckling groove is arranged on the axial center of the fan, the outer edge of one end 1111 of the ball bearing is clamped on the internal flange of the pipe seat, the axial center passes through the ball bearing, the elastic component is limited between the ball bearing and the buckling ring by the buckling ring clamped in the buckling groove, and the positioning cover is screwed on the internal thread of the pipe seat to

In the improved computer cooling fan, the top edge of the tube seat is provided with an inner flange, the bottom edge is provided with an internal thread, the axial center of the fan is provided with a snap groove, the outer edge of one end of the ball bearing is clamped on the inner flange of the tube seat, the axial center passes through the ball bearing, the elastic component is limited between the ball bearing and the snap ring by the snap ring clamped in the snap groove, the positioning cover is screwed on the internal thread of the tube seat, and one end of the fan is provided with a concave socket. has the effect of adjusting and fixing the rotating speed of the fan. But also has the advantages of improving the running stability and the service life of the bearing, preventing the shaft center from swinging, reducing the shaking of the fan blades, reducing the noise of the fan, improving the manufacturing quality rate and the like.
