摘　　要：针对目前工业领域存在的循环水冷却问题,设计采用蒸发冷却冷水机组实现循环水的冷却。该机组由立管间接蒸发冷却器、直接蒸发冷却填料、闭式换热盘管组成。对机组进行风量测试及热水试验,结果表明:机组在高湿度地区运行时,立管间接蒸发冷却器的最佳风量比(二次/一次)为0.79,机组的冷却效率高达65.2%;机组对50℃左右的循环水进行冷却,温降幅度为20℃,降温效果较好。最后针对测试中存在的主要问题提出改进措施。According to the existing issues of circulating water cooling in industrial field,the evaporative cooling chiller applied to circulating water cooling is designed.The unit consists of vertical tube type indirect evaporative cooler,packings for direct evaporative cooling and closed heat plate.The results of the air flow test and hot water test show that the optimal air volume ratio of the vertical tube type indirect evaporative cooler in high humidity area is 0.79,and the cooling efficiency of this unit is up to 65.2%;when using hot water of 50 ℃ as heat source for test,temperature drop range is 20 ℃,and the cooling effect is better.At last,the corresponding improvements are proposed aiming at the main test issues.
