Problems solved by technology

[0003] This kind of water-cooled belt used for battery cooling has a very high technical content and is extremely difficult to produce. The main difficulties in the production process include ultra-high extrusion ratio, ultra-high dimensional accuracy, and good air tightness, etc.; the product itself The main features are: wide shape, thin thickness, thin wall, small ribs, few holes, etc. The thinnest size wall thickness and rib thickness are only more than 20 wires. Most of the current market is still in the research and development stage, and there is no molding process

Abstract

The invention discloses a continuous extrusion production technology of a battery pack water cooling belt, and belongs to the technical field of production of battery pack water cooling belts. The technology comprises the following steps that 1, a die is heated to 450-500 DEG C and kept at the constant temperature; 2, a sheave (1) conveys aluminum materials (2) through friction, the temperature ofthe aluminum materials (2) is increased to 500-530 DEG C through friction, and the feeding time interval of every two adjacent aluminum materials (2) is determined; and 3, the machined water coolingbelt (8) is pulled through a take-up machine, and the pulling speed is 20-30 m / min. According to the continuous extrusion production technology of the battery pack water cooling belt, the problems that too many middle empty zones are produced since the time interval is too long, and product air impermeability is unqualified are solved, and the problems that feeding is continuously carried out since the time interval is too short, blockage occurs and extrusion cannot be achieved are also solved.

Description

technical field [0001] The invention discloses a continuous extrusion production process of a battery pack water-cooling strip, which belongs to the technical field of battery pack water-cooling strip production. Background technique [0002] The water-cooling belt is a microchannel flat tube used for liquid heat exchange of the power battery of the power supply system of the new energy electric vehicle. The cooling performance of the power battery directly affects the efficiency of the battery, and also affects the battery life and safety. , the maximum temperature of the general battery unit can reach about 60°C, increasing the application of the water cooling belt can realize rapid heating of the battery at low temperature and rapid cooling at high temperature, and control the maximum temperature of the battery below 35°C to meet high-speed + fast charging continuous driving. [0003] This kind of water-cooled belt used for battery cooling has a very high technical conten...
