摘要： A heat transmission pipe (1) is bent at a plurality of positions into a zig-zag form. A plurality of such zig-zag heat transmission pipes (1) are horizontally arranged side by side. A stack of horizontally arranged heat transmission pipes (1) is so formed that the spacings between the heat transmission pipes (1) are as small as possible. The end parts of the heat transmission pipes (1) are bent at different positions near a pipe plate (2) and inserted into the pipe plate (2). Since the heat transmission pipes (1) are stacked with very small spacings, when liquid which is sprayed onto the horizontal heat transmission pipes flows down from pipe to pipe, the liquid is spread in the direction of the heat transmission pipe by capillarity and the whole surfaces of the heat transmission pipes are well wetted. Consequently, the heat transmissivity can be improved and the size of an absorption water cooler/heater can be reduced.
摘要翻译：传热管（1）在多个位置弯曲成Z字形。多个这样的之字形传热管（1）并排水平配置。形成水平布置的传热管（1）的叠层，使得传热管（1）之间的间距尽可能地小。传热管（1）的端部在管板（2）附近的不同位置弯曲并插入管板（2）。由于传热管（1）以非常小的间隔堆叠，当喷射到水平传热管上的液体从管道向下流动时，液体在传热管的方向上通过毛细管和整体传热管的表面很好地润湿。因此，可以提高热传递率，并且可以减小吸收水冷却器/加热器的尺寸。
