Title:
FALLING LIQUID FILM HEAT EXCHANGER, ABSORPTION REFRIGERATION SYSTEM, SHIP, OFFSHORE STRUCTURE, AND UNDERWATER STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2013/035509
Kind Code:
A1
Abstract:
The present invention is configured in a manner so that, between a horizontally arranged row of heat transfer pipes (21) and a horizontally arranged row of heat transfer pipes (21) therebelow, guide plates (22A, 22B) having indentations (22a) are disposed in a manner so that the lowest sites of the indentations (22a) are disposed in the vicinity of the peak portion of each heat transfer pipe (21) at the lower side, and so even in the case of tilting in the right/left direction of the heat transfer pipes (21), a liquid (D) flowing down across the outer surface of the heat transfer pipes (21) at the upper side is transmitted to the heat transfer pipes (21) at the lower side corresponding to the heat transfer pipes (21) at the upper side in a one-to-one fashion. As a result, even when mounted in a ship, offshore structure, underwater structure, or the like, and there is tilting or swaying of the ship or the like, in a falling liquid film heat exchanger, a liquid such as a cooling medium or an absorbing liquid is distributed approximately uniformly and dripped onto the peak of the heat transfer pipes, the liquid dripping from the heat transfer pipes positioned in the upper row is caused to reliably fall to the surface of the heat transfer pipes positioned in the lower row, and a decrease in heat exchange performance is avoided.
