摘 要: 对传质型塔间冷却器的传热性能进行了试验研究。在换热管内填充金属填料后,冷却器的传热性能大大提高,传热系数比空管提高了49%~101%,所需传热温差减少,温度分布均匀。 An experimental investigation was conducted for the heat transfer performance of inter tower section mass transfer coolers.After metal packings were filled into the heat exchange tubes,the heat transfer performance of the coolers was considerably increased,the heat transfer coefficient rised by 49*$%~101*$% than that of empty tubes,the temperature difference necessary for heat transfer was reduced,the temperature was distributed averagely.
