摘要： 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.

摘要： A falling film heat exchanger in which a continuous weld circumferentially joins each tube to the outer surface of the upper, and desirably also the lower, tubesheet. The welds seal the crevices between the tubes and tubesheet holes and prevent corrosion. Since the circumferential welds cannot be deposited if the tube ends extend more than about 2 inches past the tubesheet, extensions can be added by welding.
