摘　　要： 本文简要叙述了折流杆换热器的研究进展 ,并针对合成氨中换热设备的特点对现行的折流杆换热器内部结构进行了改进设计 ,分析了其强化传热机理。介绍了这种新型换热器在合成氨变换工段和冰机系统中的应用情况及所起的节能降耗作用。 The research development of the rodbaffle heat exchanger has been reviewed, and the improved internal structure of the rodbaffle heat exchanger has been designed in accordance with the special characteristics of the heat exchangers used in the ammonia synthesis. The mechanism of heat transfer enhancement in the new design of rodbaffle heat exchanger is analyzed. The industrial application and energy saving effect of this new type of heat exchangers in the transformation section and the refrigeration system of ammonia synthesis in the nitrogen fertilizer plants have been introduced. The practical technologies are presented for the extended application of this type of heat exchangers.
