Abstract:
1. A heat sink comprising: a first base plate facing a first surface of a heat source, the first base plate including a support unit protruding from a first surface of the first base plate and spaced apart from an edge portion of the first base plate by a first gap distance and a first dissipating unit formed on a second surface opposite to the first surface of the first base plate to dissipate heat generated from the heat source; a second base plate facing a second surface of the heat source, the second base plate including a penetrating hole spaced apart from an edge portion of the second base plate by a second gap distance to hold the support unit therein and a second dissipating unit formed on a second surface of the second base plate to dissipate the heat generated from the heat source; and a coupling member positioned on an upper surface of the support unit to apply a force to the first and second base plates to thereby combine the first and second base plates to the heat source.
