利用现有的卧式管式间接蒸发冷却器搭建了模拟立管式间接蒸发冷却器实验台，并进行相关测试，在标准实验工况下，该模拟立管式间接蒸发冷却器最大温降9.2℃，最高换热效率62.4%，最佳一次空气流量为2000~2500m 3/h，最佳二次/一次风量比为0.7，最佳淋水密度1197kg/(m·h)。与卧式管式间接蒸发冷却器性能进行对比，该模拟立管式间接蒸发冷却器换热效率略低，二次空气侧阻力较大。总结出实际的立管式间接蒸发冷却器应设计为大管径、圆形换热管，布水方式采用管内直接布水。

Using the horizontal tubular indirect evaporative cooler to set up vertical tube-type indirect evaporative cooler test bench, it is concluded that the vertical tube-type cooler can reduce the temperature about 9.2℃ with 62.4%efficiency.The best product airflow is 2000~2500m3/h,andthebestworking/productairratiois0.7,andthebestwater pouring density is 1197kg/(m·h). B y comparing with horizontal tubular cooler, the vertical tubular cooler has a lower efficiency and a higher air resistance, and the real vertical tubular indirect evaporative cooler should have a rounded, heavy caliber heatexchanger tube,spray water in the tube directly.
