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.
