A cold plate and a method of forming the cold plate are provided that efficiently and cost effectively cools electrical components. The cold plate includes a flattened tube formed from a circular extruded tube to have a top surface and a bottom surface that are substantially parallel and contiguously connected by rounded corners and defining an interior space. The circular extruded tube includes a plurality of ins extending into the interior space form inner walls thereof to form a plurality of channels in said flattened tube between said fins for defining a cooling liquid passage therethrough. The fins may extend parallel to the direction that the flattened tube extends, or extend at a predetermined angle to the direction that the flattened tube extends. Also, the fins associated with the top surface may extend at an angle to the fins associated with the bottom surface to form a plurality of intersecting points which form a torturous fluid flow path.

Flattened tube cold plate for liquid cooling electrical components

A low thermal resistance, low cost cooling or heating system and method of constructing the disclosed cooling system. The system may be formed by pressing a tube into a groove in a plate without the use of interface materials or epoxy. The disclosed system includes a plate having a channel adapted to receive a tube, such that the channel holds the tube in place after the tube is press fitted into the channel, thus forming an effective cooling or heating system without the need for addition of epoxy or interface material between the tube and the plate. One or more electronic components to be cooled or heated may be attached to both sides of the disclosed cooling system with equivalent cooling effectiveness. Operation of the disclosed system involves flowing an appropriate fluid through the tube that has been press fitted into the plate.
