Abstract

The invention provides a fan wheel structure. The fan wheel structure comprises a cover body connected with a plurality of fan blades, and the cover body is arranged on a hub. The hub is provided with a top surface and an accommodating space defined on the top surface, each fan blade is provided with a combining end protruding in the accommodating space, the cover body is provided with a butt joint side and a plurality of combining grooves, the butt joint side is combined with the top surface of the hub, and the combining grooves are arranged around the cover body and separately combined with the combining ends of the fan blades so as to fix the fan blades.

Description

【Technical field】 [0001] The invention relates to a cooling element, in particular to a fan wheel structure. 【Background technique】 [0002] The fan is a common part in the field of electronic heat dissipation. It is usually made of metal or plastic. When the fan blade is made of plastic, it is made by injection molding. Therefore, the fan blade has a certain thickness usually greater than 0.3mm. It should not be too thin, so as not to break the fan blade due to the wind resistance when rotating. Therefore, reduce the thickness of the fan blade to make it an ultra-thin fan blade with considerable strength, and how to combine the ultra-thin fan blade with the hub of the fan, and how to avoid increasing the number of ultra-thin fan blades to cause uneven load on the hub The problem is that the industry needs to work hard at present. 【Content of invention】 [0003] In order to effectively solve the above problems, one object of the present invention is to provide a fan whee...
