Method of producing a liquid cooled coldplate
First Claim
1. A method of producing a liquid cooled coldplate, the method comprising:
- forming a tub from metal, the tub comprising an inlet port, and outlet port, and a plurality of pockets, wherein the plurality of pockets are formed in a top surface of the tub and are in fluid communication with the inlet port and outlet port;
forming a plurality of cooling plates by slicing fins into flat metal plates with a tool to form an enhanced surface, where the tool slices into the cooling metal layer to a depth less than the cooling metal layer thickness, and where the slicing step forces sliced material upwards, the slicing step forming the fins to a fin height extending beyond an outer surface of the cooling metal layer, then slicing across the fins at an angle to form pins which extend beyond an outer surface of the cooling plates;
installing each cooling plate into a pocket such that a chamber is formed between the tub and the cooling plate and the enhanced surface is within the chamber and in fluid communication with the chamber, the inlet port, and the outlet port;
installing electronic components onto the cooling plate on a side opposite to the enhanced surface.

Abstract
A liquid cooled coldplate has a tub with an inlet port and an outlet port and a plurality of pockets recessed within a top surface of the tub. Each pocket has a peripheral opening and a ledge, the ledge disposed inwardly and downwardly from the peripheral opening. The inlet port and outlet port are in fluid communication with the pocket via an inlet slot and an outlet slot. A plurality of cooling plates are each received by a pocket and recessed within the pocket. Each cooling plate comprises an electronics side for receiving electronics and enhanced side for cooling the cooling plate. The enhanced side of the cooling plate comprises a plurality of pins formed by micro deformation technology. The tub may be formed by extrusion.

14. A method of producing a liquid cooled coldplate, the method comprising:
-
forming a tub from metal, the tub comprising an inlet port, and outlet port, and at least one pocket, wherein the at least one pocket is formed in an outer surface of the tub and is in fluid communication with the inlet port and outlet port; forming at least one cooling plate by slicing fins into a metal plate with a tool to form an enhanced surface, where the tool slices into a cooling metal layer of the metal plate to a depth less than the cooling metal layer thickness, and where the slicing step forces sliced material upwards, the slicing step forming the fins to a fin height extending beyond an outer surface of the cooling metal layer, then slicing across the fins at an angle to form pins which extend beyond an outer surface of the cooling plates; installing the cooling plate into the pocket such that a chamber is formed between the tub and the cooling plate and the enhanced surface is within the chamber and in fluid communication with the chamber, the inlet port, and the outlet port; installing electronic components onto the cooling plate on a side opposite to the enhanced surface. - View Dependent Claims (15, 16, 17)
