Brazing furnace description
This is a brazing furnace for the cooling plate of electric car batteries. Its function is to weld two complex aluminum plates together at high temperatures. Curved channels connect the two aluminum plates, and liquid flows through them to cool the battery’s heat.
This brazing furnace is currently an important equipment for producing cooling plates for electric vehicle batteries. It not only provides good welding quality, but is also very suitable for large-scale production needs.
Battery cooling plate productive process
The battery cooling plate consists of two aluminum plates, a top plate, and a bottom plate.
The first step is to press and form the two aluminum plates using a dedicated mold. The pressing machine needs to provide sufficient force; otherwise, the aluminum plates will deform during high-temperature brazing,
The second step is to perform high-temperature degreasing on the two formed aluminum plates to ensure that there are no excess oil stains or dirt on their surface. Then, flux spraying and drying are performed.
The third step is to assemble two aluminum plates and place them flat on a tool. Please ensure that the positioning of the two aluminum plates meets the design requirements. Special positions require metal blocks to be flattened to prevent shrinkage displacement after the aluminum plates’ thermal expansion.
The fourth step is to cool the brazed battery cooling plate. Leave the brazing furnace and check that all channels and positioning are intact. If necessary, it needs to be polished to beautify its appearance.
The fifth step is to conduct a sealing test on the battery cooling plate, with a test pressure of 1.5-2 times the normal working pressure. After passing the inspection, the product can deliver to the customer.

Battery plate brazing furnace features
1. It is a noncorrosive nitrogen-protected brazing furnace, and a good atmosphere environment is critical during high-temperature brazing. The characteristics of aluminum materials will not undergo oxidation or corrosion.
2. The aluminum brazing furnace for battery cooling plates is manufactur using the latest technology, significantly reducing energy consumption compared to the previous generation of products. This ensures the atmosphere inside the furnace while reducing nitrogen consumption.
3. We have comprehensively upgraded our brilliant control system to simplify the training of complex brazing techniques. New brazing engineers can also master all the technologies quickly.
4. This brazing furnace has more than 20 temperature unit control zones, and each temperature can be independently controlled. When the temperature changes, it will not affect the entire production, ensuring stable product quality output for large-scale production.
Battery plate brazing furnace higher functions
1. The brazing furnace’s control cabinet has a WIFI module inside. Engineers can connect to the network to control the furnace remotely and update the system online.
2. The battery cooling plate brazing process requires a very important atmosphere inside the furnace. Therefore, we have installed an oxygen analyzer for the brazing furnace. Engineers can observe the screen to understand the atmosphere data inside the stove. The equipment will automatically sound an alarm if the atmosphere does not meet the technical requirements.
3. A mesh chain conveyor device with a pneumatic motor is install at the end of the brazing furnace. When the factory encounters a power outage, engineers can start the pneumatic motor to transfer the aluminum cooling plate inside the furnace to the outside, avoiding unnecessary losses
