    Abstract: A heat sink apparatus is constructed from alternating longer and shorter sheets of graphite material sandwiched together such that the longer sheets extend beyond the shorter sheets to define fins. The directions of higher thermal conductivity of the anisotropic graphite material are oriented in the plane of the sheet. The longer and shorter sheets have base ends aligned together to define a generally planar base surface for engaging an electronic device to be cooled.

    Abstract: A composite heat sink apparatus includes a metal base which has a thermal conductivity of at least about 200 W/m 0 K. The metal base is preferably constructed either of copper of aluminum. The heat sink apparatus further includes a plurality of fins attached to the base, the fins being constructed of anisotropic graphite material having a direction of relatively high thermal conductivity perpendicular to the base.
