[0002] A radiator is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. At present, radiators are used more and more widely, and there are more and more manufacturers manufacturing radiators. The market's quality requirements for radiators are also getting higher and higher. When assembling the radiator, each component needs to be welded to secure the radiator and prevent it from leaking.

[0003] At present, most manufacturers use relatively ordinary welding machines when producing radiators. They need to manually face one side of the radiator to the welding head. After welding one side, they need to manually move to the other side or the other end of the radiator to complete the welding. At the same time, they also need to manually turn the radiator over to achieve double-sided welding of the radiator. Not only can the welding quality of the product not be guaranteed, but there are also disadvantages such as high labor intensity, low work efficiency, and low degree of automation.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a radiator double straight seam welding machine is proposed. Summary of the invention

The present application adopts automatic welding with a double-head welding gun to ensure beautiful weld formation, fast processing speed and good welding quality. When one side of the heat sink to be welded is located in the rear end area of ​​the test bench after welding, the flip arm can use any method such as magnetic adsorption, pneumatic adsorption and movable clamps to drive the heat sink to flip, and flip the other side of the heat sink to be welded above the welding slot at the front end of the test bench to facilitate the handle and other accessories.

The double-head welding gun 1509 automatically welds to ensure beautiful weld formation, fast processing speed and good welding quality. When one side of the heat sink 5 to be welded is located in the rear end area of ​​the test bench 1 and the welding is completed, the flip arm 806 can use any method such as magnetic adsorption, pneumatic adsorption and movable clamps to drive the heat sink 5 to flip, and flip the other side of the heat sink 5 to be welded above the welding groove 3 at the front end of the test bench 1 to weld and install accessories such as handles.
