Description

Technical Field

[0001] The invention relates to the technical field of electric vehicles, in particular to a device which integrates the functions of riveting a water nozzle of a liquid cooling plate of an electric vehicle battery and joining an upper and lower plate. Background Art

[0002] As an important component of new energy vehicles, the working state of power batteries directly affects the performance of the entire vehicle. Therefore, the safety, life and mileage of the battery have attracted much attention from the industry. "Battery cooling" is the most important link in the entire battery thermal management process. Liquid cooling has become the mainstream cooling method that surpasses air cooling and phase change cooling due to its large specific heat capacity and high heat transfer coefficient. The most important component of this cooling method is the liquid cooling plate. The stamping and brazing liquid cooling plate has a large market share due to its advantages such as simple manufacturing process, flexible flow channel feature arrangement, and large size and specification design space. The stamping and brazing liquid cooling plate mainly includes an upper plate, a flow channel plate (lower plate) and a water nozzle (including two types of water outlet nozzles and water inlet nozzles). The production process is as follows: After the upper plate and the flow channel plate are positioned and assembled, the water nozzle is installed on the upper plate by spot welding or riveting, and then the whole is input into the brazing furnace for brazing.

[0003] In the prior art, the assembly of the upper and lower plates of liquid cooling plate products and the installation of water nozzles are usually done manually offline, using spot welding for fixing. The degree of automation is low, and a large number of operators are required on the production line. Although some production lines are equipped with online riveting equipment for the water nozzles and the upper plate, the water nozzles are manually picked up and inserted into the preset installation holes of the upper plate before pressure riveting. This is a semi-automatic installation operation, which not only has low work efficiency but also poses a safety risk. In addition, after the upper plate and the water nozzle are riveted, they need to be transferred to another operating area to be assembled with the lower plate, and the continuity of the process is poor.
