Patent ID: 7975479

Claim:
A heat exchanger, comprising: an inlet configured to receive a fluid at a first temperature; an outlet configured to discharge the fluid at a second temperature lower than the first; and a plurality of first fluid passageways disposed to conduct the fluid from the inlet to a manifold chamber, the first fluid passageways forming a first section fabricated from a metal material, the manifold chamber providing communication between the first fluid passageways and a plurality of second fluid passageways, the second fluid passageways forming a second section fabricated from a thermally conductive polymer, each first fluid passageway being linear between the inlet and the manifold chamber, each second fluid passageway being linear between the manifold chamber and the outlet, each first fluid passageway being coaxial with one of the second fluid passageways, and wherein the first fluid passageways have a flow path length of about one half the length of the second passageways.
