Abstract:
1. A heat exchanger comprising: a first inlet tank having a first fluid inlet port; a first outlet tank having a first fluid outlet port; a housing connecting the inlet tank and the outlet tank to at least partially define a first flow path between the first inlet port and the first outlet port; and a plurality of embossed plate pairs extending into the first flow path from and substantially perpendicular to a first wall of the housing, each plate pair defining a circuitous second flow path extending between a second inlet port and a second outlet port, the second inlet port in fluid communication with a second inlet tank and the second outlet port in fluid communication with a second outlet tank, the second inlet port and the second outlet port being formed by the plurality of plate pairs, the first flow path extending across each of the second flow paths; wherein said first wall of the housing comprises a plurality of elongated spacers interleaved with said plurality of embossed plate pairs, each of the spacers extending at least partially along an edge of one of the plates and at least partially around the second inlet port and the second outlet port, and wherein the plurality of embossed plate pairs are spaced away from a second wall of the housing opposite said first wall to accommodate differences in thermal expansion between the plurality of embossed plate pairs and the housing.
