摘　　要：为了改善目前间接蒸发冷却器的亲水性,提高冷却器的湿球效率,并实现间歇式布水,降低循环水泵能耗。采用吸水性较好的新型多孔陶瓷材料制作管式间接蒸发冷却器,利用其丰富的比表面积来增大水膜与工作空气的接触面积;利用其较好的吸水性快速蓄水,实现间接蒸发冷却器的间歇性布水,缩短循环水泵运行时间。对其性能进行了实验研究,对其湿球效率、温降,EER等参数进行了测试计算。为了了解其优越性,并与其他间接蒸发冷却器进行了性能对比。结果表明多孔陶瓷管式间接蒸发冷却器的EER最高,1.5m管长时湿球效率最高。其较好的性能证明其有很好的应用前景。In order to improve the hydrophilicity of the current indirect evaporative cooler,improve the wet bulb efficiency of the cooler,and realize intermittent water distribution,reduce the energy consumption of the circulating pump.In this paper,a new type of porous ceramic material with better water absorption is used to make a tubular indirect evaporative cooler.Its rich specific surface area is used to increase the contact area between water film and working air.The intermittent water distribution of the indirect evaporative cooler can be realized by using its good water absorption and fast water storage,and the running time of the circulating pump can be shortened.The wet bulb efficiency,temperature drop,EER and other parameters were measured and calculated.In order to understand its superiority,the performance was compared with that of other indirect evaporative coolers.The results show that the EER of the porous ceramic tubular indirect evaporative cooler is the highest,and the wet bulb efficiency is the highest when the pipe length is 1.5 m.Its good performance proves that it has a good application prospect.
