Liquid Cold Plate with Friction Stir Welding Process
Friction stir welding liquid cold plate can be used extrusion techniques, which are used to form the flow passages of the cold plate directly and the flow passages are connected through by machining any blockage. The assembly is sealed by the friction welding technique with a high production throughput and low cost. This technique is not suitable for applications with higher power density or too many screw holes on the surface since this will create constraints for the flow passages. The main applications include the cooling of power batteries, heating devices, and integrated cooling products such as standard power modules. And the dimensions and routes of the internal passages can be designed with greater freedom. This is suitable for thermal management products with a larger power density, irregular heat source layouts within a limited space. The main applications include wind power converters, electric motor controllers, lasers, special power supplies, and supercomputers and ser.
