Description

Technical Field

[0001] The utility model mainly relates to the field of copper flow channel processing of liquid cooling plates, and in particular to a copper flow channel bending device for liquid cooling plates. Background Art

[0002] Batteries generate a lot of heat during operation. If this heat cannot be dissipated in time, it will cause component failure or thermal stress to cause component damage, which will lead to battery failure. Some flow channels in the automotive battery liquid cooling plate are made of copper tubes, which are manually bent into a U-shaped structure. During mass production, the processing efficiency is relatively low.

[0003] In the invention patent application with application number CN202022066306.0, application publication date 2021.06.04, and name "Liquid Cooling Plate Copper Channel Bending Device", it includes a base plate, a guide arm and a forming plate. The forming plate is fixedly arranged on the base plate, and the outer side surface is provided with a forming groove 1 adapted to the copper runner tube. The guide arm is hingedly arranged on the forming plate and rotates on the outer side of the forming plate. The guide arm is provided with a pressure wheel adapted to the copper runner tube, and the pressure wheel is movably arranged on the guide arm. The pressure wheel is provided with a forming groove 2 adapted to the copper runner tube. The forming groove 2 and the forming groove 1 form a shape adapted to the copper runner tube. The device bends the copper runner tube into a preset shape through the cooperation of the pressure wheel on the guide arm and the forming plate.

[0004] However, the above-mentioned bending device cannot protect the copper flow channel of the liquid cooling plate, that is, the copper tube during the bending process. When the bent copper tube is in the bending process, there is a situation where the bending angle is too large, resulting in the tube wall being broken. Utility Model Content
