ABSTRACT:
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.
