Micro fan adopting H-shaped retaining ring

Abstract

The invention discloses a micro fan adopting an H-shaped retaining ring. The micro fan adopting the H-shaped retaining ring comprises a retaining ring, a bearing and a fixing ring. The retaining ringis arranged in the fixing ring. The retaining ring comprises a retaining ring body. A first protruding block is arranged in the retaining ring body. A second protruding block is arranged above the retaining ring body. The bearing is pressed on the retaining ring body and the second protruding block. According to the micro fan adopting the H-shaped retaining ring, the H-shaped retaining ring is formed by the retaining ring body, the first protruding block of the retaining body and the second protruding block above the retaining ring. Pulling force of fan blades can be improved by the first protruding block of the retaining ring. Through the second protruding block above the retaining ring, buffer effect is achieved in the stress process of the retaining ring, and taking by workers is facilitated during assembling, multiple mounting of the retaining ring can be prevented, oil storing space of the fan can be improved to a certain degree.

Description

technical field [0001] The invention relates to the technical field of micro fans, in particular to a micro fan using an H-shaped buckle. Background technique [0002] The motherboards of electronic devices are equipped with different electronic components, such as CPU and other electronic components. However, with the rapid development of electronic related industries, the CPU computing speed and efficiency have been rapidly improved, but the heat generated by it is relatively increasing. The higher the temperature, the higher the heat even due to the sealing factors such as the casing. Therefore, in order to effectively dissipate the heat and maintain the normal operation of the CPU at the allowable temperature, a heat sink and cooling fan are usually installed on the CPU to assist in heat dissipation and effectively prevent the CPU from being damaged by overheating. [0003] Most heat dissipation fans use buckle rings, which play a vital role in the operation of the fan....

AI Technical Summary

Problems solved by technology

[0004] Most of the above-mentioned existing buckles are flat blocks. The material of the buckle is generally polyester material, which is softer than plastic material. If the fan is subjected to external force, it is easy to cause the fan blades to get stuck or even fall off.

The problem of causing certain safety hazards to the operator, the technical problem to be solved by the present invention is to provide a micro fan using an H-shaped buckle
