Abstract

A condenser/evaporator heat exchanger comprising a plurality of vertically oriented panel units spaced moderately from one another. Each panel unit comprises a pair of thin film plastic sheets bonded to one another along a plurality of vertically extending bond lines transversely spaced from one another at regular intervals. The two sheets form between adjacent pairs of bond lines a plurality of vertical tubular condensing chambers adapted to receive pressurized steam. Brine is directed onto the outer surfaces of the panel units at the upper ends thereof, the brine descending down the outer surfaces of the panel units to be in heat exchange relationship with the steam inside the tubular condensing chambers.
