Title: SPLIT HEAT SINK
Abstract:
Provided herein are various split heat sinks. In one approach, a heat sink apparatus includes a first heat sink coupled to a second heat sink, and a membrane coupled to a first side of the first heat sink and disposed between the first heat sink and the second heat sink. In some approaches, the membrane includes a phase change material (PCM). The heat sink apparatus may further include a semiconductor device coupled to a second side of the first heat sink. In some approaches, the heat sink apparatus includes a support frame coupled to the second heat sink. In some approaches, the heat sink apparatus includes additional PCM disposed within the first heat sink and/or the second heat sink. In some approaches, the heat sink apparatus includes one or more fluid conduits formed therein.
