US Patent 7975479 Bi-material corrosive resistant heat exchanger

A heat exchanger for a fluid handling system is disclosed. The heat exchanger may have an inlet configured to receive a fluid at a first temperature, and an outlet configured to discharge the fluid at a second temperature lower than the first. The heat exchanger may also have at least one fluid passageway disposed to conduct the fluid from the inlet to the outlet. The at least one fluid passageway may have a first section fabricated from a first material, and a second section fabricated from a dissimilar second material. At least one of the first and second materials may include a thermally conductive polymer.
