FALLING FILM TYPE HEAT EXCHANGER, ABSORPTION REFRIGERATION SYSTEM, SHIP, OFFSHORE STRUCTURE AND UNDERWATER STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a falling film type heat exchanger that substantially uniformly distributes liquid such as a refrigerant or an absorption liquid and drops the liquid on apexes of heat exchanger tubes in the falling film type heat exchanger, can make the liquid dropped from the heat exchanger tubes located in an upper row surely fall on surfaces of the heat exchanger tubes located in a lower row, and can avoid the lowering of heat exchanging performance even if being mounted to a ship, an offshore structure, an underwater structure or the like and applied with the inclination and the oscillation of the ship or the like, and to provide an absorption refrigeration system, the ship, the offshore structure, the underwater structure.SOLUTION: A guide plate 22A having a recess 22a is arranged between a row of heat exchanger tubes 21 which are aligned in a horizontal direction and a row of the heat exchanger tubes 21 which are aligned in a horizontal direction below the row so that the lowest portion of the recess 22a is located in the vicinity of apex portions of the respective heat exchanger tubes 21 at the lower side, and fluids falling down on external surfaces of the respective heat exchanger tubes 21 at the upper side are transferred to the heat exchanger tubes 21 at the lower side corresponding to the upper-side heat exchanger tubes 21 in a one-on-one manner even if the heat exchanger tubes 21 are inclined in left and right directions.
