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. 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.
Claims5
A liquid heat transfer plate comprising
- a unitary, one-piece plate having a first surface and a second surface opposite said first surface and a plurality of fluid channels in a first direction in said plate between said first and second surfaces, said plate having first and second ends perpendicular to said first direction, said fluid channels extending from said first plate end to said second plate end, each of said fluid channels having a serrated surface, at least one of said first and second surfaces having a flat surface;
- a wire mesh in each of said fluid channels to increase turbulent flow therein;
- a first manifold near said first plate end perpendicular to said fluid channels and fluidly connected thereto;
- a second manifold near said second plate end perpendicular to said fluid channels and fluidly connected thereto;
- and
- first and second caps fixed to said first and second plate ends respectively, said first cap blocking said fluid channels at said first plate end and said second cap blocking said fluid channels at said second plate end.
