Abstract
A heat and mass transfer device for transmitting heat between a fluid flowing within a pipe and a solution flowing on the outside of the pipe. The device comprises at least one vertically upright tubular pipe and a U-shaped folded metal fin strip twisted helically around the periphery of the pipe. The spacing of the fins on the pipe is such that a pulsating flow of the solution flowing on the outside of the pipe is achieved.
