Patent ID: 7013668

Claim:
A method for making a cold plate unit, comprising: a) placing a coil basket having a fluid system and a coolant system having coolant lines in a mold, i) the fluid system comprising a plurality of fluid lines each comprising a plurality of loops, and ii) the coolant system comprising at least one inlet manifold, at least one outlet manifold and a plurality of coolant line segments running between said inlet and outlet manifolds, each comprising a plurality of loops, wherein the coolant lines comprise stainless steel tubing, wherein the inlet and outlet manifold each comprise a piece of tubing having a diameter of from about 0.5 to 1 inch and a length of from about 3 to 5 inches, with the coolant lines being welded into the side of the manifold tubing, and wherein the plurality of coolant line segments disposed between the inlet manifold and the outlet manifold provide at least three fluid paths therebetween; b) adding a molten metal into the mold, wherein the molten metal is selected from the group consisting of aluminum and an aluminum alloy; c) solidifying the metal around the coil basket to form a solidified metallic body; d) removing the solidified metallic body from the mold; e) providing a layer of insulation around the solidified metallic body; and f) providing an outer shell covering the insulation.
