Processing technology of battery cooling plate

Abstract

The invention discloses a processing technology of a battery cooling plate. The battery cooling plate comprises a cooling upper plate and a cooling lower plate, the cooling upper plate and the coolinglower plate are welded together, and friction stir welding or laser welding is adopted as the welding manner. A cooling channel coiled zigzag is arranged on the cooling upper plate, the welding areaof the battery cooling plate comprises the positions around the periphery of the battery cooling plate by one circle and between the adjacent parts of the cooling channel, the periphery of the batterycooling plate is welded to avoid outside leaking, and the positions between the adjacent parts of the cooling channel are welded to avoid bypass leaking of the cooling channel. In this manner, pollution can be reduced, the success rate of welding is high, the production takt is short, and the product cost is remarkably reduced; the cleanliness of welded products is remarkably improved, and the service of a heat management system can be prolonged easily; and energy consumption of processing equipment is low.

Description

technical field [0001] The invention relates to the technical field of battery cooling plate processing, in particular to a battery cooling plate processing technology. Background technique [0002] The battery system of electric vehicles currently on the market uses a battery cooling plate as the main component of the thermal management system; the cooling plate adopts a brazing process, and the cooling plate is welded together to form a cooling channel. Since the large-size cooling plate (generally 1.5mx1m) uses the brazing process, the size of the brazing equipment is large, the energy consumption demand is high, the production site is required to be large, and the output rate is not high; at the same time, the brazing needs to add flux, which has a relatively high High pollution, will pollute the coolant. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a processing technology for battery cooling plates,...
