摘　　要：简述了管式间接蒸发冷却器的原理结构,并对管式间接蒸发冷却器的换热管管长设置为1 m,在不同二次/一次风量比的条件下对风量、温度、相对湿度、温降参数等进行实验测试,与1.5 m管式间接蒸发冷却器进行测试对比。测试结果表明,1 m管式间接蒸发冷却器二次/一次空气风量比为0.75时,湿球效率较高为55.6%。对影响降温效果的因素进行简要的分析,与1.5 m管式间接蒸发冷却器进行对比分析,提出在条件允许的前提下优先采用1.5 m管式间接蒸发冷却器。Briefly tubular indirect evaporative cooler＇s principle and structure, and the tubular indirect evaporative cooler for heat pipe length is set to lm, In different the secondary/product air ratio of air condition, experiment test of temperature, relative humidity and the parameters of temperature drop, and contrast test with 1.5m tubular indirect evaporative cooler. Test results show that when lm tubular indirect evaporative cooler secondary/product air volume ratio is 0.75, wet ball efficiency is 55.6%. Influence factors of cooling effect briefly analysis, comparative analysis with 1.5m tubular indirect evaporative cooler, the paper puts forward the condition allowed under the premise of give priority to the 1.5m tubular indirect evaporative cooler.
