Aluminum radiator of improved riveting-embedding structure and riveting method

Abstract

The invention discloses an aluminum radiator of an improved riveting-embedding structure and a riveting method. After a riveting-embedding portion of each radiating aluminum fin is subjected to surface activation treatment, a nonporous solid blocking layer and a porous viscidity layer are attached to the surface of the riveting-embedding portion; after riveting-embedding grooves of an aluminum substrate are subjected to surface activation treatment, an aluminum oxide passivating film layer is attached to the surface of each riveting-embedding groove; and the riveting-embedding portions are in interference fit with the riveting-embedding grooves after riveting-pressing machining is conducted, clearances formed between the riveting-embedding portions and the riveting-embedding grooves are filled with the porous viscidity layers of the riveting-embedding portions after riveting-pressing deformation, and the porous viscidity layers of the riveting-embedding portions are in engaging fit with the aluminum oxide passivating film layers of the riveting-embedding grooves. According to the aluminum radiator of the improved riveting-embedding structure and the riveting method, the process is simple, riveting is firm, structure loosing or falling is not prone to occurring, and the heat conduction speed at the riveting joint is high.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to an aluminum radiator with an improved riveting structure and a riveting method. Background technique [0002] At present, most radiators are made of aluminum substrates. The radiators include an aluminum substrate and a plurality of aluminum fins fixed on the aluminum substrate. The aluminum fins are fixed on the aluminum substrate by riveting. , but the riveting is not firm, the aluminum fins are prone to loosening, and the aluminum fins will also come out accidentally when affected by external forces. In relatively harsh environments such as high or low temperatures, due to heat Aluminum fins are more likely to loosen and fall off accidentally due to expansion and contraction, so it is necessary to improve them. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide an aluminum radiator with an imp...
