Claim 14:
15. A method of cooling a microelectronic device housed inside an enclosure, comprising:
i) providing
a) a microchannel heat absorber having an outer heat transfer surface and comprising at least one layer defining a plurality of microchannels having a cross-sectional dimension of less than 1000 microns and terminating at a first end thereof in a cool side manifold and at a second end thereof in a warm side manifold, the microchannels containing a liquid working fluid that absorbs heat and forms a vapor upon flowing therethrough from the first end to the second end,
b) a heat sink for receiving and condensing the vapor to reform the liquid working fluid and for discharging the liquid working fluid, and
c) one or more pipes flowably connecting the warm side manifold of the heat absorber to the heat sink and flowably connecting the cool side manifold of the heat absorber to the heat sink, wherein the one or more pipes are connected so as to permit simultaneous flow of the vapor from the heat absorber to the heat sink and of the liquid working fluid from the heat sink to the heat absorber when heat is applied to the heat absorber,
ii) installing the microchannel heat absorber inside the enclosure with its outer heat transfer surface proximate an outer heat transfer surface of the microelectronic device, and
iii) installing the heat sink outside the enclosure.
