Abstract

A heat dissipation device dissipates heat generated by a heat-generating electronic element mounted on a top surface printed circuit board. The printed circuit board defines a plurality of first through holes. The heat dissipation device comprises a heat spreader located at a top side of the printed circuit board. The heat spreader defines a plurality of second through holes corresponding to the first through holes, respectively. A first heat sink is located over the heat spreader, and a plurality of second heat sinks is located at a bottom side of the printed circuit board. A plurality of heat pipes extending through the second through holes of the heat spreader and the first through holes of the printed circuit board to thermally connect the first and second heat sinks to the heat spreader.
