Abstract
A process for fabricating a low-cost high-efficiency liquid cold plate is described. The process uses a metal extrusion designed with internal fluid channels that have their major cross-sectional axes aligned perpendicular to the major surfaces of the extrusion. Particular dimensions for the cross-sections of the fluid channels and their spacings permit the extrusion process to be performed simply. A simple process for fabricating fluid inlet and outlet manifolds, creating turbulent flow inside the fluid channels, a method for capping the extrusion ends, and a method for improving the surface contact with heat generating components is described.
