为模拟空气分离装置中冷凝蒸发器的实际运行状况，采用１ｍ长的板翅式单元作冷凝蒸发器的微膜热虹吸沸腾通道，使之部分地沉浸在液氮池中进行浅池沸腾试验，实验结果表明，当板翅式单元露出液面部分从０增加到４０ｃｍ时，在整个试样始终保持相同热流密度的条件下，其沸腾传热温差仅增加０．１９Ｋ；只要热流密度维持在某一最小起始值之上，即使沉浸深度减少４０％，冷凝蒸发器仍将处于高效和安全运行状态。
In order to simulate the actual operating conditions of the condensing evaporator in the air separation plant, a 1 m long plate-fin unit was used as the thermosyphon boiling channel of the micro-membrane of the condensing evaporator, so that it was partially immersed in a liquid nitrogen pool for shallow pool boiling test, The experimental results show that when the exposed part of the plate-finned unit increases from 0 to 40 cm, the boiling heat transfer temperature difference increases by only 0.19 K with the same heat flux throughout the sample. As long as the heat flux density is maintained at a certain level Above a minimum starting value, the condensing evaporator will remain in efficient and safe operation even with a 40% reduction in immersion depth.
