| 摘 要： | 在考虑壁面两侧空气温度实际变化的前提下，对间接蒸发冷却传热过程中影响yong效率的主要因素，如一次空气进口温度、一、二次空气流速之比，二次空气相对湿度，一、二次通道宽度之比以及壁面润湿率进行了分析研究，为实际换热器设计提供理论依据。

| Abstract: | On the basis of the actual temperature variety beside a heat transfer plate ,the exergy efficiency of an indirect evaporate process is analyzed numerically. The effects of a wide variety of parameters such as the velocity and temperature of the air stream,the inlet relative humidity,the wettablity of the plate and the channel width are investigated. The results are useful for the design of an indirect evaporative heat exchanger. |
