Abstract
An expandable and contractable sealed environment is provided by a rigid frame member and a pair of deformable heat transfer elements fixed to the frame member. The frame member is located between two heat-producing electronic assemblies. A coolant agent is pumped into the sealed environment to flex the membranes and cause them to conformally contact the pair of electronic assemblies. Excess heat in the assemblies is then allowed to pass across the membranes and into the coolant agent for dissipation purposes. In order to remove the electronic assemblies, the pressure of the coolant agent is reduced, which permits the heat transfer element to return to its nondeformed state removed from the assembly. Thus, the electronic assemblies can be removed without the need to open fluid couplings.
