Claim 18:
19. A method of cooling a microelectronic device housed inside an enclosure, comprising
causing a liquid working fluid to flow through a plurality of microchannels in a microchannel heat absorber that includes an outer heat transfer surface proximate an outer heat transfer surface of the microelectronic device within a microelectronic device enclosure and having a cross-sectional dimension to the center of the channel that is equal to or less than the thermal boundary layer thickness for a working fluid,
causing at least some of the working fluid to form a vapor and absorb heat from the microelectronic device,
receiving and condensing the working fluid vapor from the microchannel heat absorber to discharge heat from the fluid outside the enclosure and reform the liquid working fluid, and
continuously returning the condensed working fluid from outside of the enclosure back to the heat absorber in the enclosure.
