Abstract:
1. A heat exchanger for transferring heat from a heat source to a working fluid, the heat exchanger comprising a housing having a plurality of grooves formed in a surface of the housing, the grooves having a first end and a second end and defining fluid flow channels open at one end, each channel having a fluid flow inlet at the open end and closed at the other end, and a fluid flow outlet at the closed end, the fluid flow inlets at the open ends of an alternating first set of the fluid flow channels adjacent to the first end of the grooves, and the fluid flow inlets at the open ends of a second set of alternating fluid flow channels adjacent to the second end of the grooves, wherein the first set of the fluid flow channels and the second set of the fluid flow channels are arranged such that fluid in immediately adjacent channels flows in opposite directions, the housing defining a distribution manifold having a pair of openings onto the surface of the housing, one of the pair of openings adjacent the first end of the grooves and the other of the pair of openings adjacent the second end of the grooves for supplying fluid to the fluid flow channels, wherein the one and the other of the pair of distribution manifold openings extend continuously the full length of the ends of the plurality of grooves such that the openings are in fluid communication with the open ends of the fluid flow channels, and the housing defining a return manifold for removing fluid, wherein the return manifold is in fluid communication with the fluid flow outlets of the alternating first set of fluid flow channels at the second end and the alternating second set of fluid flow channels at the first end.
