Description

Technical Field

[0001] This utility model relates to equipment for installing centrifugal fans, and more specifically to an installation device for centrifugal fans. Background Technology

[0002] Centrifugal fans are widely used in various industries, mainly for heat dissipation of products. The installation device of the centrifugal fan directly affects the performance of the centrifugal fan and the product processing cost. The processing cost, assembly cost, maintenance cost and reliability of the installation device determine the manufacturing cost and reliability of the product.

[0003] Currently, most centrifugal fan mounting devices used in power supply products are two-part assembly structures. The upper part is the centrifugal fan connector used to install the fan body, and the lower part is the guide vane connector used to install the centrifugal fan's guide vane. These two parts are assembled into a whole, which involves many assembly steps and has high procurement costs. Furthermore, the lower part of the structure usually requires punching a process fold before using mounting supports to connect the centrifugal fan. This method of fixing the centrifugal fan results in poor stability. Utility Model Content
