vacuum brazing oven China Supplier

vacuum furnace outline

The Vacuum brazing oven is an important production equipment for aluminum heat exchangers, mainly used for brazing aluminum fins, aluminum plates, and cores assembled. These products are widely used in fields such as aviation, aerospace, petroleum, chemical, and energy.

Vacuum brazing furnaces play an important role in the welding process of these aluminum products. When using a vacuum brazing oven, aluminum heat sinks and aluminum tube sheets are placed on special supports and inside the furnace. These components are heated to a high-temperature state in the furnace, usually above 620℃.

During the heating process, the air between the aluminum heat sink and the aluminum tube sheet is extracted, creating a vacuum environment. In a vacuum environment, aluminum heat sinks and aluminum tube sheets can be welded together.

Advantages of vacuum brazing oven

1, Vacuum brazing significantly improves the corrosion resistance of products, avoids pollution caused by brazing flux and the cost of waste treatment, and has better safety production conditions.

2, Vacuum brazing can save expensive metal brazing flux and does not require complex cleaning processes, thereby reducing production costs.

3, The welding layer of vacuum brazing has better flowability, which can weld products with complex structures and narrow channels, thereby improving the product yield.

4, Compared with other welding methods, the internal structure of the Vacuum furnace has a longer service life, which can reduce the maintenance cost of the furnace.

5, Vacuum brazing is suitable for various materials, such as aluminum, aluminum alloys, copper, copper alloys, stainless steel, alloy steel, and low-carbon steel, among which aluminum and aluminum alloys are one of the most widely used materials.
