摘　　要：从强化传热的理论出发,以管式间接蒸发冷却器为研究对象,就如何开发和研究低能耗和高效的管式间接蒸发冷却器,阐述了几种强化传热传质的方法。通过对比分析,采用亲水铝箔管材,在管外包覆吸水性纤维织物或网状结构材料,在换热管外涂敷有机无机复合亲水膜,是几种行之有效的增强管式间接蒸发冷却系统中换热管传热传质的措施。经过强化传热传质优化设计的管式间接蒸发冷却器,冷却效果好,具有广阔的应用前景。In order to seek efficient tubular indirect evaporative cooler, Several methods of heat and mass exchange enhancement were elaborated, according to the theory of heat exchange enhancement. By contrast and analysis, several methods of heat and mass exchange enhancement for tubular indirect evaporative cooling system were stated. By optimization design, efficiency of the tubular indirect evaporative cooler was enhanced and application prospect of it was expanded.
