Aviation fuel is used as the coolant for a microchannel heat sink for airborne electronics. The use of preexisting aviation fuel as a coolant medium eliminates the weight, size and expense of a separate liquid system dedicated solely to electronics cooling. The heat sink is comprised of a body of material having high thermal conductivity and in which are formed a set of parallel closed-ended microchannels on the order of 0.001 in. by 0.004 in. separated by a distance of 0.001 in.

A method of extracting heat from an electronics device located in an aircraft, comprising the steps of: thermally coupling said electronics device to a heat sink comprising a body of material having relatively high thermal conductivity, a plurality of microchannels having walls operating as cooling

A method of extracting heat from an electronics device located in an aircraft, comprising the steps of: thermally coupling said electronics device to a heat sink comprising a body of material having relatively high thermal conductivity, a plurality of microchannels having walls operating as cooling fins and being sufficiently narrow to provide convective heat transfer coefficients and a fin density which are sufficiently high to enable high heat density cooling and, thereby, to enable effective device cooling with aviation fuel as the coolant; coupling a coolant comprising fuel used to power said aircraft to and from said microchannels so that the fuel flows through said microchannels to extract, by convection, heat generated by said electronics devices.
