Description

[0002] For a liquid cooling system with the liquid cooling plate located below the battery module, the battery cells are fixed into a module by plastic parts. The module is placed on the liquid cooling plate, and there is a gap of about 1 mm between the heat dissipation surface of the battery cells and the liquid cooling plate. Usually, thermal conductive adhesive is used to bond the heat dissipation surface of the battery cells and the liquid cooling plate to better achieve heat conduction. Therefore, it is necessary to manufacture a caulking tooling according to the shape and arrangement position of the heat conduction surface of the battery cells, and then manually apply glue at the corresponding position of the liquid cooling plate with the help of the caulking tooling. The following problems exist in this process: a) The amount of glue applied manually is uneven. Excessive glue amount causes waste; too little glue amount results in air pockets between the heat dissipation surface of the battery cells and the liquid cooling plate. b) Manual glue application requires frequent glue replacement (about 350 ml per glue stick), with slow speed, low efficiency and high labor cost. c) From the start to the end of glue application, the process time is long, which affects the bonding performance of the glue.
