Electric Vehicle Controller Aluminium Die Cast Liquid Cold Plate Heat Sink

The base material of this liquid cold plate heat sink is aluminium. A longitudinal channel is formed on the base through friction stir welding, and then it is milling through at both ends of the transverse interval, and the channel is closely connected by friction stir welding. In the direction of more compressive strength and thinner thickness, this technology has been successfully applied to the liquid cold plate of high power laser equipment.

The surface treatment technology of hard anode is made possible by the material with similar composition and the friction stir welding process without adding solder.

This friction stir welding process liquid cold plate heat sink finished with hard anodized, so the laser equipment can withstand the test of harsh service environment and long-term fluid erosion.
