ABSTRACT:
A modular microchannel heat exchanger for cooling a heated region and a method for making the device. A first section of the device features an array of thin copper sheets which are etched with rows of elongated holes that pierce the sheets, coated with silver and held together with the holes aligned. These holes form a microchannel having a desired aspect ratio. A second section of the device has a series of thin copper plates which are etched as apertures, coated with silver and stacked in a sequence on the sheets of the first section, the plate closest to the sheets having elongated apertures oriented transversely to the microchannel of the sheets, the apertures combining further from the sheets into circular apertures to fit a coaxial inlet and outlet conduit where unitary or pipe flow occurs. The inlet conduit is, through the branching series of plates, in communication with alternately spaced elongated apertures adjacent to the microchannel of the sheets, and the outlet conduit is in communication with the other alternate elongated apertures. A case for both sections has an inlet and outlet chamber with holes that the inlet and outlet conduits plug into.
