Abstract

The present invention provides a heat exchange element for particular use in a film heat exchanger, such as a distillation system. The heat exchange element (100) includes a substrate (102) having a first surface (104) and an opposing second surface (106). The first surface (104) acts as a condenser surface. The heat exchange element (100) further includes a composition disposed on at least a portion of the second surface. The composition has an exposed hydrophilic surface so as to provide a hydrophilic evaporator surface (108) due to the composition being hydrophilic in nature. In contrast, the condenser surface is typically hydrophobic in nature. The use of the hydrophilic composition eliminated the nucleation of vapor bubbles and prevents gas film (or gas blanket) formation on the evaporator surface. As a result, the thermal resistance through the heat exchange element is decreased and the efficiency of the heat exchange element is increased.
