露点蒸发冷却技术的发展及其在数据机房冷却中的应用

Development of dew-point evaporative cooling technology and its application to data room cooling

露点蒸发冷却可以将空气温度降至进口空气湿球温度以下,理想状态下可达到进口空气的露点温度。露点蒸发冷却器冷却性能受湿通道内表面润湿材料、冷却器结构及运行参数影响。概述了露点蒸发冷却器在湿通道材料选择、冷却器结构及运行参数优化方面的研究现状及研究进展,以及其在数据机房冷却中的不同应用形式。

The dew-point evaporative cooling can decrease the air temperature below the inlet air wet-bulb temperature, ideally reaching the dew-point temperature of inlet air. The cooling performance of dew-point evaporative cooler is affected by the surface wetting material of wet channel, cooler structure and operational parameters. Summarizes the status and development of dew-point evaporative cooler in the aspects of the selection of wet channel materials, the optimization of cooler structure and operational parameters, as well as its different application forms in data room cooling.
