摘　　要：以管式间接蒸发冷却器实验台为依托,着重对其传热传质过程进行分析与计算。合理设置实验台初始状态参数,测试管式间接蒸发冷却器在兰州地区气候条件下的实际应用效果。在获得理想实验数据后,通过查阅文献选择误差范围较小的传热传质关联式,计算出换热过程中主要技术参数,为今后在兰州地区气候条件下制造出适用性更高的管式间接蒸发冷却器提供较为可靠的理论设计依据,并进一步证明在空气能比较丰富的西北地区管式间接蒸发冷却器推广应用大有前景。The heat and mass transferring are analyzed and calculated with the tubular indirect evaporative cooler experiment table. The reasonable initial parameter for experiment table is set up to test the actual operation effect of the tubular indirect evaporative cooler in Lanzhou climate. After obtaining ideal experimental data, the heat and mass transfer correlations with small error are selected through the lit- erature, calculating main technical parameters in the heat exchange process. It will provide reliable theoretical design guidelines for producing tubular indirect evaporative cooler of highly practical value in the future in Lanzhou climate conditions, and further prove that application and dissemination of the tubular indirect evaporative cooler features for promising outlook in the air-rich northwest district.
