Abstract

A falling film heat exchanger of the plate type has spaced heat exchange elements. Vapor enters the elements and after condensation therein by heat exchange with liquid flowing as a film on the outer surfaces of the elements, condensate is discharged from the bottoms of the elements. The coolant liquid is itself evaporatively cooled by a flow of cooling air passing outside the heat exchange elements, within a casing that encloses the elements. The cooling air may even be warmer than the coolant liquid so long as the air is not saturated. The heat exchange elements themselves can be arranged mutually parallel or in radial array, and the directions of flow of vapor and cooling air can be concurrent or counter current, with either or both of these media flowing upwards or downwards. <IMAGE>
