Abstract
A heat pipe structure is incorporated directly into the metal baseplate of a circuit card thereby eliminating thermal contact resistance between the baseplate and the heat pipe assembly. Components are mounted on a copper circuit layer bonded to a dielectric layer in a first portion of the baseplate with a second portion of the baseplate/heat pipe assembly extending into a heat sink/cold plate condensing area for removal of heat generated in the component portion.
