Extrusion techniques 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.
