Abstract
A thermal management system includes a distributor plate secured to and parallel to a circuit board. The circuit board has a module secured thereto and the distributor plate defines an area on an inner surface thereof secured to or otherwise in thermal contact with the module. Heat pipes embedded in the distributor plate include a portion over the module and a portion over the circuit board outward from the module. A portion of the heat pipes outward from the module may be substantially perpendicular to a direction of airflow between the circuit board and distributor plate. The module may be located closer to one edge of the circuit board and the heat pipes may according extend from adjacent that edge to an opposite edge of the circuit board. An inward facing surface may include fins extending toward the circuit board and the fins may be contoured to the circuit board.
