Cooperative enterprise: a well-known new energy passenger vehicle heat exchange company in Hebei Province

Problems encountered by enterprises:

New energy vehicle battery radiator is a water-cooled plate. Because the water-cooled plate is different from the special structure of the fuel vehicle radiator, the problem of flux overflow and uneven appearance color after welding has been plagued by enterprises in the industry. This cooperative enterprise is the first Put forward the requirement of processing appearance after soldering, and solve the problem of flux residue and uneven color.

The technical solution proposed by our company:

After receiving the company's product improvement request, we actively cooperate with the company to determine the process, and go to the laboratory and the production site for testing and verification many times. After many adjustments in the process details, we finally adopted our company's LT-IV aluminum products degreasing and whitewashing liquid and LT-VII aluminum products surface oxide treatment agent two products. In the process of formulating the process, our company fully considers the difficulties that the company may encounter in the actual production process, and has conducted technical discussions with the company's process production technology quality inspection departments for many times to simplify the process operations in the production process as much as possible and formulate Reasonable treatment plan finally decided to use these two products at room temperature. After the two products are used together, they meet the enterprise's unified requirements for the appearance of the water-cooling plate. The outer surface of the treated water-cooling plate is better than most companies in the industry, and it is very competitive in the industry.
