摘要： 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.

摘要： An improved mass transfer heat exchanger in which heat transmission surfaces are more effectively used and having excellent mass transmission characteristics. Heat transmission pipes are arranged vertically in a tank, extending through a partition board dividing the tank into upper and lower chambers. A solution lead-in pipe supplies a high-density solution to be subjected to heat exchange to the upper chamber, and a pump draws a low-density solution obtained by mass exchange out of the lower chamber and delivers a part thereof to the upper chamber. The upper and lower chambers are communicated through a return pipe which delivers to the lower chamber an intermediate-density solution obtained by mixing the high-density solution and a surplus of the low-density solution in the upper chamber. A vapor lead-in pipe supplies vapor to the lower chamber. The intermediate-density solution flows down the heat transmission pipes, passing through gaps between the partition boards and heat transmission pipes.
