Abstract:
A heat exchanger system comprising:an electronic heat pump having a hot side and a cold side; a heat exchanger on at least one side of said electronic heat pump, each heat exchanger comprising: a thermally conductive base having a first surface and a second surface; said first surface being flat and adapted to make intimate surface contact with a corresponding flat surface of said electronic heat pump; said second surface being obverse to said first surface; a plurality of thermally conductive walls extending from and in sealing contact with said base; a plurality of narrow channels defined between adjacent walls of said plurality of walls, said narrow channels being axially aligned and further comprising inlet ends, outlet ends, and tapered side walls; a manifold on at least one side of said electronic heat pump corresponding to each of said at least one heat exchanger, each manifold comprising: a thermally conductive cover disposed on and in sealing contact with top ends of said plurality of walls to closed said plurality of narrow channels; a recess defined between said base and said cover for receiving said plurality of walls; a fluid inlet to said recess proximate said inlet ends of said plurality of narrow channels; a fluid outlet from said recess proximate said outlet ends of said plurality of narrow channels; and wherein a flow of a heat transfer liquid from said fluid inlet to said fluid outlet of said manifold only occurs through said closed narrow channels from said inlet end to said outlet end of said heat exchanger.
