Embodiment Construction

[0031] The above-mentioned purpose of the present invention and its structural and functional characteristics will be described according to the preferred embodiments of the accompanying drawings.

[0032] see figure 1 , figure 2 , is the perspective and top view of the first embodiment of the centrifugal fan blade structure of the present invention, as shown in the figure, the centrifugal fan blade structure includes: a hub 11;

[0033] The hub 11 has a plurality of fan blades 111, and the fan blades 111 are formed by extending from the circumference of the hub 11 to the opposite direction of the hub 11. There is a flow channel 111a and an air outlet 111b between the fan blades 111. An air inlet 111c, the air outlet 111b and the air inlet 111c are respectively arranged at two ends of the flow channel 111a and communicated with the flow channel 111a, and the air outlets 111b are not equidistantly arranged.

[0034] The fan blade 111 has a first end 1111 and a second end 111...

Abstract

Disclosed is a centrifugal fan blade structure. A plurality of fan blades are arranged on a hub and extend along the direction opposite to the hub from the circumference of the hub. 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 has an air inlet on the top and bottom of the frame, and an air outlet on its side. When it is running, the fan blades rotate to drive the surrounding air to flow, and the axial device ente...
