Abstract
Abstract A cooling apparatus for stacked components. Heat generating components may be mounted on two sides of a first printed circuit board. A second circuit board may be stacked over the first circuit board with a thermally conductive frame disposed between the two boards. The frame includes a cross member thermally coupled to the heat generating component on the top side of the first circuit board. The heat generating component on the bottom side of the first circuit board is thermally coupled to one leg of a thermally-conductive strap. The strap has a second leg that is thermally coupled to one end of the thermally conductive frame and also to one end of a heat distribution member mounted adjacent the second circuit board. The apparatus functions to channel heat from the first board's top and bottom components to the heat distribution member via the thermally-conductive frame and the thermally-conductive strap.
