本文就肋片管对不同的工况进行了大量的实验,将实验结果进行了分析比较,得到了一些有益的结论。肋片管对溴化锂降膜式发生器的传热传质有强化作用,管外换热系数的强化幅度约为43.7～55.3％,放汽范围的强化幅度约为27～49.2％。这些工作对选用适合于溴化锂降膜式发生器的强化传热管有着指导作用。 In this paper, a large number of experiments on different working conditions of finned tube were carried out. The experimental results were analyzed and compared, and some useful conclusions were obtained. The tube of finned tube has a strengthening effect on the heat and mass transfer of the lithium bromide falling film generator. The enhancement range of the heat transfer coefficient outside the tube is about 43.7-55.3% and the enhancement range of the steam releasing range is about 27-49.2%. These efforts are instrumental in choosing enhanced heat transfer tubes for lithium bromide falling film generators.
