    • 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.
    • 要解决的问题:为了提供一种基本均匀地分配诸如制冷剂或吸收液体的液体并将液体滴落在降膜型热交换器的热交换器管的顶点上的降膜式热交换器,可以使 从位于上排的热交换器管滴下的液体确定地落在位于下排的热交​​换器管的表面上,并且即使安装在船舶,海上结构,水下也能避免热交换性能的降低 结构等,并应用于船舶等的倾斜和振荡,并提供吸收制冷系统,船舶,海上结构,水下结构。 解决方案:具有凹部22a的引导板22A布置在排列在水平方向上的一排热交换器管21和排列在行的下方的水平方向上的一排热交换器管21之间 凹部22a的最下部位于下侧的各热交换管21的顶点附近,并且在上侧的各热交换管21的外表面上落下的流体被转移到 即使热交换器管21在左右方向上倾斜,也可以一对一地对应于上侧热交换管21的下侧的热交换器管21。 版权所有(C)2013,JPO&INPIT
