Multi-flow channel high-frequency welded pipe for power battery cooling module of electric car

Abstract

The invention discloses a multi-flow channel high-frequency welded pipe for the power battery cooling module of an electric car. The multi-flow channel high-frequency welded pipe comprises a high-frequency welded pipe body, multiple heat dissipation pits which are integrally formed in one or more outer surface of the high-frequency welded pipe body, and multiple groups of cooling flow channels which are arranged in the high-frequency welded pipe body at equal intervals, wherein the high-frequency welded pipe body is an aluminum alloy flat pipe, and the material of the aluminum alloy flat pipeis multi-layer composite aluminum alloy. By the mode, the multi-flow channel high-frequency welded pipe is reasonable and compact in structure, a cold-roll formed aluminum alloy flat pipe is adopted,the heat dissipation pits are integrally processed in the outer surface of the aluminum alloy flat pipe, multiple groups of cooling flow channels are arranged in the aluminum alloy flat pipe, so thatthe aluminum alloy flat pipe has the characteristics of small volume, light mass, high heat dissipation efficiency and the like, meanwhile, multi-layer composite aluminum alloy is adopted as the material of the aluminum alloy flat pipe, the corrosion resistance of the cooling flow channels can be effectively improved, so that the service life of the cooling flow channels is prolonged, and the welded pipe can satisfy the power battery cooling module of the electric car in use.

Description

technical field [0001] The invention relates to the technical field of high-frequency welded pipes, in particular to a multi-channel high-frequency welded pipe for a power battery cooling module of an electric vehicle. Background technique [0002] Although electric vehicles get rid of traditional fuel engines, their power sources, power batteries, require heat dissipation and cooling during work, just like traditional engines. At present, most batteries are cooled by water-cooled plates made of aluminum extruded profiles through friction stir welding. This type of water-cooled plate generally has defects such as large volume, heavy weight, and low heat transfer efficiency. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a multi-channel high-frequency welded pipe for electric vehicle power battery cooling module, which can solve the above-mentioned defects existing in the existing water-cooled plate.
