Rotary structure of a heat dissipating fan

Abstract

The invention discloses a rotary structure of a heat dissipating fan capable of maintaining the operation of an axle of the heat dissipating fan along a single axial line by means of a base of the heat dissipating fan and two fixing members disposed at two contact ends of the axle of the heat dissipating fan, so that the axle will not be deviated or collided to produce abnormal noises when the heat dissipating fan is operated.

Benefits of technology

[0004] The primary objective of the present invention is to overcome the foregoing shortcomings and avoid the existing deficiencies by providing a rotary structure of a heat dissipating fan capable of maintaining the operation of an axle of the heat dissipating fan along a single axial line by means of a base of the heat dissipating fan and two fixing members disposed at two contact ends of the axle of the heat dissipating fan, so that the axle will not be deviated or collided to produce abnormal noises when the heat dissipating fan is operated.

[0005] Another objective of the present invention is to provide a rotary structure of a heat dissipating fan that comprises a contact end of the axle having an external diameter smaller than the axle to reduce the contact area and friction between the axle and the fixing member, and thus avoiding the high heat produced by frictions.

Problems solved by technology

If it is unable to effectively dissipate the heat produced by the operation of the product, then the related components of the product may be overheated and damaged by the excessively high temperature, or more seriously a fire accident may occur.

As to the current technology, the volume of installing the heat dissipating fan is limited, and thus the performance of the heat dissipating fan mainly depends on the rotary speed of the heat dissipating fan.

However, the axle and the bearing will produce high heat due to excessive frictions produced by high-speed rotations, and the axle will be deviated easily to collide with the bearing and produce abnormal noises.

Therefore a durable wearing-resisting ceramic bearing is developed, but the ceramic bearing has a high hardness, and thus it is very difficult to be fixed or designed.

Furthermore, the high heat issue produced by the friction still cannot be avoided effectively.
