Abstract:
1. A package for an integrated circuit employing indirect liquid cooling comprising: a substrate having a first microchannel for allowing liquid coolant to flow from a bottom surface of the substrate to a top surface of the substrate and a second microchannel for allowing liquid coolant to flow from the top surface of the substrate to the bottom surface of the substrate; an integrated circuit attached to the top surface of the substrate; a lid for surrounding the integrated circuit; a lid attachment for sealing the lid to the substrate; and a microchannel heat exchanger coupled to the first and second microchannels arranged between a top surface of the integrated circuit and the lid, wherein the top surface of the integrated circuit comprises one or more heat-producing portions of the integrated circuit and wherein the microchannel heat exchanger is directly coupled to the heat-producing portions.
