Abstract
A heat exchanger, or the heat exchanger component of a multi-function device, comprising a polymeric heat transfer material. The heat exchanger exhibits reduced voltage-induced breakdown of the polymeric material, which can lead to cross-contamination of the two fluids. Either or both of two approaches may be employed. The first approach modifies the polymeric material to increase its resistance to breakdown. The second approach employs at least one electrical bridge between the fluids in the two sides of the heat exchanger, thus placing the two fluids into electrical equilibrium.
