Claim:
A heat exchanger, comprising: a rectangular-shaped sheet having first and second rectangular-shaped sheet portions coupled together at a bent edge of the rectangular-shaped sheet such that the first and second rectangular-shaped sheet portions are disposed proximate to one another and generally parallel to one another, outer edges of the first and second rectangular-shaped sheet portions being coupled together such that an interior region is formed between the first and second rectangular-shaped sheet portions, the bent edge defining an outer planar surface, the bent edge having first and second apertures extending therethrough; a first inlet port having a tubular portion and a ring-shaped portion, the ring-shaped portion being coupled to an end of the tubular portion and extending substantially perpendicular and outwardly from the tubular portion, the ring-shaped portion being disposed on and coupled to the outer planar surface of the bent edge, the ring-shaped portion being further disposed over the first aperture; and a first outlet port being disposed on the bent edge over the second aperture, such that fluid can flow through the first inlet port and into the interior region and then through the first outlet port.
