Quick positioning structure for riveting of thin cooling fins and thin cover plate

Abstract

The invention discloses a rapid positioning structure for riveting thin heat dissipation fins and thin cover plates, which includes a plurality of thin heat dissipation fins and a positioning plate; the plurality of thin heat dissipation fins are arranged vertically, and each thin heat dissipation fin There are positioning protrusions extending from the tops of the fins; the positioning plate is arranged on a plurality of thin heat dissipation fins, and a plurality of positioning holes are opened on the positioning plate, and the aforementioned positioning protrusions respectively pass through the positioning holes and extend upwards and align with the corresponding positioning holes. Cooperate with positioning. By providing a positioning plate, the positioning convex part is used to extend upward through the positioning hole and cooperate with the positioning hole for positioning, so that when the thin cover plate is installed, each riveting convex part and each riveting hole can be quickly aligned Installation saves time and effort, and during the riveting process, the positioning plate can effectively prevent the thin heat dissipation fins from swinging left and right, and the riveting convex part is not easy to come out of the riveting hole, thereby improving the quality of riveting installation and bringing more benefits to production. convenient.

Description

technical field [0001] The invention relates to the technology in the field of radiators, in particular to a rapid positioning structure for riveting thin heat dissipation fins and thin cover plates. Background technique [0002] The heat sink usually includes a heat dissipation base and heat dissipation fins arranged on the heat dissipation base. In order to improve the heat dissipation effect, the current heat sinks generally use thin heat dissipation fins. However, due to the weak strength of a single thin heat dissipation fin, it is easy to deform. , it is necessary to install thin cover plates on multiple thin heat dissipation fins to enhance the overall strength of the radiator. [0003] In order to improve the assembly efficiency of the thin cover plate, riveting is used in the prior art to fix the thin cover plate and multiple thin heat dissipation fins, such as the thin heat dissipation fin disclosed in the Chinese invention patent application (application number 20...

AI Technical Summary

Problems solved by technology

However, this method cannot be positioned before and during assembly, and it is difficult to achieve rapid alignment installation between each convex part and each riveting hole, which is time-consuming and laborious. It is easy to swing left and right, and the convex part is easy to come out of the riveting hole, thus affecting the quality of riveting installation
