Abstract
A composite liquid cooled plate is disclosed having a heat transfer plate, preferably made of copper, on one or both sides of a core, which is preferably plastic. The core has flow channels to direct water against the heat transfer plates underneath the 'hot' areas of the heat transfer plates, thereby providing a very low thermal resistance. The assembly remains lightweight by restricting the use of copper or other conducting materials to only the areas requiring thermal conduction.
