Beschreibung
Zusammenfassung:	A microchannel heat sink is manufactured from graphite materials. A heat sink member has at least a first thermal contact surface for making thermal contact with an electronic device. The heat sink member is constructed of at least a first sheet of compressed particles of exfoliated graphite, the first sheet having two major surfaces. At least one of the major surfaces has a first plurality of microchannels formed therein for carrying coolant fluid. Said microchannels each have a length parallel to one of said major surfaces and have a cross section normal to said length. The cross-section has at least one dimension below about 1000 microns.
