[0011] Beneficial effects of the utility model:

[0012] By setting up a sealing mechanism, when in use, the drive motor is started to drive the threaded screw to rotate, realizing automatic lifting of the lifting platform and the sealing cover, thereby sending the battery liquid cooling plate material into the brazing furnace body and automatically discharging the material after processing is completed, reducing manual intervention, saving the physical strength of the staff, and improving production efficiency and the continuity of the production line. At the same time, the sealing cover is tightly closed with the brazing furnace body, effectively preventing the entry of external air and impurities, ensuring the purity and stability of the internal environment of the brazing furnace, improving the processing quality of the battery liquid cooling plate material, and reducing the production of defective products.

[0013] By setting up a water cooling mechanism, when in use, after waiting for the processing to be completed, the water in the water storage tank is transported to the water cooling pipe of the brazing furnace body through the water pump, and the heat in the furnace is absorbed and taken away by the flow of water. Not only is the cooling efficiency high and the temperature in the furnace can be quickly reduced, but it also helps to protect the brazing furnace body and its internal equipment from high temperature damage and extend the service life of the equipment. At the same time, the cooled water enters the cooling box through the circulation pipe for re-cooling, and can then be recycled for the next cooling process, reducing the waste of water resources, reducing the need for additional cooling equipment or energy due to high temperature, saving production costs, and achieving energy-saving and environmental protection effects.

The sealing cover 9 is tightly closed with the brazing furnace body 2, which effectively prevents the entry of external air and impurities, thereby ensuring the purity and stability of the internal environment of the brazing furnace.

[0022] The water cooling mechanism includes a water storage tank 12 and a cooling box 13 fixedly connected to the inside of the workbench 1, a valve pipe 14 fixedly connected between the water storage tank 12 and the cooling box 13, a water pump 15 fixedly connected to one side of the workbench 1, the water inlet end of the water pump 15 fixedly connected to a water pumping pipe 16, the other end of the water pumping pipe 16 fixedly connected to the water storage tank 12, the water outlet end of the water pump 15 fixedly connected to a water delivery pipe 17, the other end of the water delivery pipe 17 passes through the brazing furnace main body 2 and is fixedly connected to the upper end of the water cooling pipe 4, a circulation pipe 18 is fixedly connected to the surface of the cooling box 13, the other end of the circulation pipe 18 passes through the brazing furnace main body 2 and is fixedly connected to the lower end of the water cooling pipe 4, the water source in the water storage tank 12 is transported to the water cooling pipe 4 of the brazing furnace main body 2 by the water pump 15, and the heat in the furnace is absorbed and taken away by the flow of water, thereby quickly reducing the temperature in the furnace.
