狭缝沸腾板翅式单元传热性能的实验研究

Experimental Study on Heat Transfer Performance of a PlateFin Exchanger Unit

对采用新型沸腾传热强化措施的工业用板翅式冷凝蒸发器单元试样的传热特性进行了实验研究，实验结果表明：本文的实验单元与现行的６０００ｍ３／ｈ空分装置的板翅式主冷凝蒸发器相比，换热系数提高了近一倍，传热温差下降了４０％～５０％。

An experimental study on the heat transfer characteristics is carried out in a platefin condenserboiler unit which is provided with microfilm boiling heat transfer enhancement method. The experimental rsults show that compared to the existing platefin condenserboilers in a 6000m3/h air separation unit, the heat transfer coefficient is almost increased more than one time and the heat transfer temperature difference is less than one half of it.
