Product Description
The Aluminum vacuum brazing furnace is used for core welding of plate and bar heat exchangers. It is equipment for welding various complex components in a high-temperature vacuum environment, and the entire brazing process does not require any flux.
This equipment consists of a high-temperature vacuum chamber, vacuum valve, vacuum pump, Roots pump, transformer, control system, and other components to form a complete aluminum brazing furnace.
Its working principle is to place the assembled aluminum heat exchanger core into a high-temperature vacuum chamber and heat the aluminum material in a vacuum environment. When the temperature reaches 600+℃, a layer of solder on the surface of the aluminum material melts and mixes.
Afterward, it rapidly cools down and welds all aluminum parts to form a complete heat exchanger core.

Aluminum vacuum brazing furnace Advantages
- Good welding quality
The aluminum core of the exchanger is brazing in a vacuum environment, and the aluminum material does not produce an oxide film during welding. The longer insulation time fully utilizes the welding, making the welding points full and firm.
- Fully automatic control
Workers only need to place the product into the aluminum vacuum furnace and close the furnace door. The equipment will automatically operate according to the set brazing program without workers needing to supervise the entire process.
- Reduce environmental pollution
Less smoke and dust are generated during the brazing process, and the gas extracted by the vacuum pump is discharged into the atmosphere after passing through an air filter without causing any pollution.
- Specialized forklift
This vacuum aluminum brazing furnace has a dedicated forklift, and its special steel is scientifically design and made. It is very suitable for loading in vacuum furnaces, making it convenient for workers to quickly load and remove aluminum heat exchangers into and out of the furnace.
- Widely applicable
This aluminum vacuum furnace is suitable for welding various aluminum alloy materials, which can be used in aerospace, automotive manufacturing, and electronic components.
- Good insulation performance
A cooling water circulation device is in the middle of the entire vacuum aluminum brazing furnace body. During high-temperature brazing, the surface temperature of the furnace body will not exceed room temperature, providing a good experience for the entire working environment
