摘　　要：针对板翅式换热器的气液两相流换热问题,利用工艺模拟软件Aspen Hysys,建立了5种不同冷流组分的板翅式换热器模型。通过比较分析,得出了不同冷流组分气液混合性能对板翅式换热器的换热面积、对数温差和最小温差的影响,为板翅式换热器优化设计提供了新的依据。In order to analysize the heat transfer of the gas-liquid interphase in the plate-fin heat exchanger, 5 models with different cold flow components are built by applying the process simulation software Aspen Hysys. Through the comparative analysis, the effects of the gas-liquid mixing performance of different cold flows on the heat exchange area, the logarithm temperature difference and the minimum temperature difference are obtained, which is of great importance in the optimal design of the plate-fin heat exchanger.
