Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a water-cooling plate vacuum brazing clamp. Background Art

[0002] The water-cooled plate, also known as the liquid cooling plate, is a component of the water-cooled radiator. It is a component that exchanges heat through liquid cooling. It has the advantages of being quiet, stable in cooling, and less dependent on the environment. Welding is a very important process in the manufacturing process of the water-cooled plate. The welding process of the water-cooled plate is mainly divided into three categories: energized diffusion bonding, vacuum brazing, and stir friction welding. Vacuum brazed water-cooled plates are widely used in the radiator field because of their flexible design structure and high welding efficiency.

[0016] The joint to be vacuum brazed is located directly below the adjustment and positioning assembly, and the brazing film is located between the joint to be vacuum brazed and the water-cooled plate core. By adjusting the nut, the spring begins to pressurize the joint below, so that the gap between the joint, the brazing film and the water-cooled plate core surface becomes smaller until the gap reaches the brazing requirement (usually 0.1mm), and then stop adjusting the nut.

[0017] Furthermore, in the above-mentioned water-cooling plate vacuum brazing fixture, the fixing block is an "L"-shaped structure, and a threaded hole is opened on the "-" of the fixing block.
