Abstract
A composite heat sink apparatus includes a metal base which has a thermal conductivity of at least about 200 W/m°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.
