Abstract
A heat sink has a base plate that has a first central portion, a second central portion, and a periphery, a first plurality of heat pipes embedded in the base plate that are arranged to convey heat away from the first central portion, and a second plurality of the heat pipes embedded in the base plate that are arranged to convey heat away from the second central portion, each of the heat pipes of the first and second pluralities having a hot end for receiving heat flow and a cool end for releasing heat flow. A switch package comprises an inner casing half mounted to a module facing surface of the heat sink base plate, a semiconductor module mounted to the module facing surface of the heat sink within the inner casing half, and an outer casing half that encloses the heat sink.
