Patent ID: 7637112

Claim:
A heat exchanger comprising: a plurality of first plates having channels defined therein with each channel having an inlet and an outlet, having channeling ports passing through the plates, and where each first plate has an upper and a lower face, wherein the first plate channels carry a fluid to be cooled; a plurality of second plates having channels defined therein with each channel having an inlet and an outlet, having channeling ports passing through the plates, and where each second plate has an upper and a lower face, wherein the second plate channels carry a coolant; wherein the plates are arranged in an alternating sequence where the lower face of a first plate is in sealing contact with the upper face of a second plate and the lower face of the second plate is in sealing contact with the upper face of another first plate, the channels in the first plates are in fluid communication through the channeling ports in the second plates, and the channels in the second plates are in fluid communication through the channeling ports in the first plates and wherein at least one of the first or second plates further comprises a micro-turbine disposed within a channel.
