Gas encapsulated cooling module

A gas encapsulated cooling module for heat generating elements comprising:

• a substrate;
• one or more heat generating components mounted on said substrate;
• a heat conductive cap sealed to said substrate enclosing said one or more heat generating components;
• the wall of said cap opposite the substrate containing elongated openings therein extending toward said heat generating components and on the same centers with respect thereto,
• a resilient member located in said cap in communion with the inner end of said openings;
• one or more thermal conductive elements each located in one of said openings forming a small peripheral gap between the opening wall and said associated thermal conductive element, said resilient member urging said thermal conductive element into contact with one of said heat generating components forming a heat transfer interface therewith;
• a thermal conductive inert gas located within said cap filling the peripheral gaps and said heat generating element conductive element interface;
• heat removal means associate with said cap for externally removing the heat generated by said heat generating means from said cap.
