Liquid cooled metal thermal stack for high-power dies

摘要

The present invention provides a system for conducting heat away from an electrical component wherein the system has an elastically deformable member providing thermal communication with an electrical component. The system for conducting heat energy in an electronic assembly includes an electrical component, an elastically deformable member, and a housing. The elastically deformable member is placed in a compressed position between the electrical component and the housing such that the elastically deformable member is fixed into an assembled location. The elastically deformable member conducts heat energy away from the electrical component into the housing where it is dissipated into the environment. Since the compressed position fixes the location of the elastically deformable member, the system does not require a mechanical fastening to the electrical component thereby reducing thermo-mechanical fatigue. The elastically deformable member is made of a metal material allowing it to easily conduct the heat energy.
