Patent ID: 7139172

Claim:
An integrated microchannel cooler device for cooling an IC (integrated circuit) chip having a non-uniform power map, the integrated microchannel cooler device comprising: a plurality of alternating input and output manifolds that extend in a same direction within the integrated cooler device; and a plurality of heat exchanger zones, wherein each heat exchanger zone comprises a plurality of thermal microfins which define a microchannel pattern of microchannels which extend between an adjacent input and output manifold to provide fluid flow paths between the adjacent input and output manifold, wherein the microchannel pattern of one or more of the heat exchanger zones is varied to provide a heat transfer performance that corresponds to an expected power map of the IC chip; and wherein the input and output manifolds and microchannel patterns of the heat exchanger zones are structured to provide an average fluid velocity in a region of a heat exchanger zone that corresponds to an expected hot spot region of the IC chip, which is substantially the same as, or at least within about 50% of, an average fluid velocity in other regions of the heat exchanger zone that do not correspond to an expected hot spot region of the IC chip.
