| 摘 要： | 回顾和分析现有间接蒸发冷却器的热工性能和数学模型,并在分析管式间接蒸发空气冷却器传热、传质过程及特点的基础上,建立针对管式间接蒸发空气冷却器热工计算模型。基于模型中管外二次空气侧空气与水膜之间的传热、传质系数是影响模型精度的重要因素,对管外二次空气侧空气与水膜之间的传热、传质系数进行深入分析,将模型用于水平单管外蒸发传热、传质系数的计算,并将计算结果与文献中的实验数据进行对比,证明所选模型的正确性,为下一步对管式间接蒸发空气冷却器整体热工性能的数值模拟奠定坚实的基础。

| Abstract: | Reviewes and analyzes the thermal performance and mathematical model of indirect evaporative cooler.Based on the analysis of the heat and mass transfer processes of indirect evaporative air cooler,establishes the thermal performance model for tube-type indirect evaporative air cooler.Due to the heat and mass transfer coefficients between the secondary air and water film around the tube are the most important factors to the accuracy of the established model,so selects and modifies carefully the heat and mass... |
