Abstract

The invention discloses a heat sink with a riveting structure, comprising a heat sink body and a bracket, wherein the heat sink body comprises a base and a plurality of heat sink fins, wherein the heat sink fins are parallel to each other and are arranged on the base at intervals; Forming a groove body between the outermost adjacent heat dissipation fins. The bracket comprises a fixed position, two bending positions and two mounting positions, wherein the fixed position is in the shape of a strip, the bending positions are respectively located at both ends of the fixed position, and the mounting positions are respectively located at the outside of the bending position. The fixing position is riveted in the groove body. The invention also discloses a riveting process of the radiator, whichis simple in riveting process, compact in structure and high in heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of heat sinks, and more specifically, to a heat sink with a riveted structure and a riveting process thereof. Background technique [0002] A radiator is a general term for a series of devices used to conduct and release heat. When installing radiator products in the prior art, screw holes or rivet holes are generally processed on the radiator. This processing method is prone to problems such as loose installation and easy falling off of the radiator, which in turn affects the heat dissipation effect of the radiator. Therefore, it is necessary to improve the installation structure of the radiator. Contents of the invention [0003] The main purpose of the present invention is to overcome the above disadvantages and provide a heat sink with a riveted structure and a riveted process thereof, which has a compact structure, high heat dissipation effect, and simple riveted process. [0004] Technical scheme o...
