Abstract
A falling film heat exchanger of the shell and tube type has the tubes positioned in concentric rings. A liquid distribution box is positioned above the tube upper ends. Short pipes extend downwardly from the box to feed liquid between the rings of tubes to distribute the liquid uniformly to the tubes. The box desirably rotates slowly. Also, the pipes desirably extend between upwardly extending tube ends so as to provide a uniform pool of liquid which overflows uniformly into the tubes.
