Riveted construction of thin cooling fins and thin cover plate

Abstract

The invention discloses a riveted construction of thin cooling fins and a thin cover plate. The riveted construction comprises multiple thin cooling fins and a thin cover plate, wherein the multiple thin cooling fins are vertically arranged, the thin cover plate covers the multiple thin cooling fins, and a bulge part extends out of the top of each thin cooling fin; multiple rivet holes are formedin the thin cover plate, and the bulge part of each thin cooling fin penetrates through the corresponding rivet hole to extend upwards and is riveted and fixed with the rivet hole through rolling by arolling device. The bulge part extends out of the top of each thin cooling fin, the multiple rivet holes are formed in the thin cover plate in a matched manner, and the bulge parts are riveted and fixed with the rivet holes through rolling by the rolling device, so that a traditional manual welding mode is replaced, assembly efficiency is greatly improved, manpower consumption is reduced, and meanwhile, defective rate of products is effectively reduced.

Description

technical field [0001] The invention relates to the technology in the field of radiator manufacturing equipment, in particular to a riveting structure of a thin heat dissipation fin and a thin cover plate. 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. In the prior art, manual welding is mostly used for the assembly of thin cover plates. This assembly method is not only inefficient and labor-intensive, but also the thin cover plates are easily welded through, resulting in defects. Therefore, it is necessary to study a scheme to solve t...
