Water-Cooled Plate for Die-Cast and Friction-Welded New Energy Vehicles

This die-cast friction-welded heat sink is made of aluminum. Longitudinal channels are formed on the base using die-cast friction welding, and holes are then milled through both ends of the channels at transverse intervals; the channels are tightly joined via friction welding. This technology has been successfully applied to water-cooling plates for new energy vehicle control equipment, offering higher compressive strength and thinner profiles. The surface of this water-cooled heat sink has undergone a hard anodizing process, resulting in a smooth, burr-free finish that enables the equipment to withstand harsh operating environments and long-term fluid erosion, making it a worthy choice.
