[0002] see Figure 5 , a conventional fan wheel structure 10, which is disclosed in U.S. Patent No. 6,814,542. The fan wheel structure 10 includes a hub 11 and an axis 12. The top 13 of the hub 11 will be integrated with plastic due to different product requirements. The injection molding method forms the arc surface 14 with different radians. In order to meet the needs of different products, it is often necessary to prefabricate wheel hub molds of different specifications to meet the different requirements of the radians of the top 13 of the hub 12, but this also increases the cost of the mold. In addition When manufacturing the hub 12, the thickness D of the top 13 will gradually decrease from the center position outward, so that the top 13 of the hub 12 forms the arc surface 14, but this also causes waste of material for the top 13
[0003] Furthermore, in the prior known technology, since the thickness D of the top 13 gradually decreases from the central position outward, after the hub 12 is formed, the top 13 of the hub 12 will be affected by the thickness D of the top 13. The shrinkage rate (shrinkage amount) of each part of the top 13 is inconsistent due to the difference, which makes the size of the hub 12 difficult to control after forming
[0004] In addition, since the shrinkage rate (shrinkage) of each part of the top 13 is inconsistent, the hub 12 is easily deformed after the hub 12 cools down. When the hub 12 is rotated by a cooling fan, the hub 12 will Shaking is generated, thus generating gas turbulence and turbulence noise, which increases the eddy current loss, and because of the shaking of the hub 12, the cooling fan generates friction and friction noise

The invention relates to a combined type fan wheel structure which comprises a hub, an axis set and a flow guide protection cover. The flow guide protection cover and the hub are individuals manufactured respectively. The flow guide protection cover and the hub are combined through the axis set, so that the flow guide protection cover and the hub are combined into a whole; and therefore the flow guide protection cover and the hub can be combined according to product needs, and the prefabrication cost of a hub mold is reduced.
Description
technical field [0001] The invention relates to a combined fan wheel structure, in particular to a combined fan wheel structure in which a diversion shroud and a wheel hub are combined by an axial center. Background technique [0002] see Figure 5 , a conventional fan wheel structure 10, which is disclosed in U.S. Patent No. 6,814,542. The fan wheel structure 10 includes a hub 11 and an axis 12. The top 13 of the hub 11 will be integrated with plastic due to different product requirements. The injection molding method forms the arc surface 14 with different radians. In order to meet the needs of different products, it is often necessary to prefabricate wheel hub molds of different specifications to meet the different requirements of the radians of the top 13 of the hub 12, but this also increases the cost of the mold. In addition When manufacturing the hub 12 , the thickness D of the top 13 gradually decreases from the central position to form the arc surface 14 on the top ...
