When the disc-shaped fan wheel 10 rotates, a fluid is driven from the air inlet 211 to enter through the plurality of connecting pieces 13 and then enter the inner edge 121 (or the air inlet side) of the plate body 12 and then pass through the plurality of upper protrusions 125 After reaching the first gap 126 , it flows out from the outer edge 122 (or called the air outlet side), and then flows out from the flow channel 25 toward the air outlet 24 . Furthermore, when the disc-shaped fan wheel 10 rotates, the air is driven from the plurality of through holes 223 to enter through the plurality of connecting pieces 13 and the inner edge 121 (or the air inlet side) of the plate body 12, and then pass through the plurality of downholes. The convex body 127 and the second gap 128 then flow out from the outer edge 122 (or the air outlet side), and then flow out from the air outlet 24 through the flow channel 25 .

To sum up, with the above structure, and compared with the prior art, the disc-shaped fan wheel 10 structure of the present case reduces the periodic noise problem caused by the existing fan wheels that are all composed of blades, and the plurality of connectors are selected. As ribs, it can achieve a disc-shaped fan wheel structure that can drive airflow regardless of forward rotation or reverse rotation. If the plurality of connecting members 13 are selected as blades, the composite disc-shaped fan wheel structure can not only reduce the periodic noise problem, but also maintain the intake air flow.

The present invention has been described in detail above, but the above is only a preferred embodiment of the present invention, and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the scope of application of the present utility model should still belong to the scope of the patent of the present utility model.
