Abstract

A centrifugal fan blade structure comprises a hub and a fan blade body group. The hub is provided with an extension portion, and the fan blade body group comprises a plurality of fan blade bodies which extend outwards from the extension portion. A flow passage, an air outlet and an air inlet are formed between every two fan blade bodies. The air outlets and the air inlets are formed in the two ends of the flow passages and communicated with the flow passages. The air outlets are arranged in a non-equidistant mode, and accordingly, operation noise can be greatly reduced.

Description

technical field [0001] A centrifugal fan blade structure, especially a centrifugal fan blade structure that can reduce the noise of a centrifugal fan during operation. Background technique [0002] With the rapid development of the current electronic industry, the performance of electronic components continues to improve. As the calculation speed increases, the heat generated by it will generate relatively large amounts of heat. If the heat cannot be dissipated immediately, the computing performance of the electronic components will decrease. If it is serious, it will cause burning. Therefore, in a limited system space, a small centrifugal fan is used as a heat solution. The centrifugal fan mainly includes a frame, a fan hub, and multiple rings arranged outside the fan hub. Each fan blade body has an air inlet on the top and bottom of the frame body, and an air outlet on its side. When it is running, the fan blade body rotates to drive the surrounding air to flow, and the sh...
