Abstract:
A cold plate, planar in shape, is machined to provide an interior cavity having a plurality of thermally conductive members which transfer any thermal energy absorbed by the cold plate to a chilled water stream flowing through the interior cavity. Electronic cards are mechanically and thermally married to copper conduction plates which mount on a surface of the cold plate. The cold plate can hold up to nineteen pairs of conduction plate/electronic card assemblies. Thermal energy generated by the electronic circuit cards flows into the conduction plate and then into the chilled water stream flowing in cold plate. The chilled water is provided by a cooling system as known in the art. The cold plate also provides a large central through-hole through which the electronic cards are electrically connected to a computer system. The cold plate through-hole allows the cold plate to enjoy close proximity to the thermal source providing a path of high conductance for the thermal energy to be dissipated.
