Entropy Analysis on Transport Processes in Tubular Indirect Evaporative Cooler and Its Optimization

根据不可逆热力学理论，定义了管式间接蒸发冷却器的熵产单元数，并给出了管式间接蒸发冷却器的熵产单元数的解析表达式．分析了换热器结构参数与最小熵产单元数间的关系，指出了提高管式间接蒸发冷却器热力学完善度的基本方向．

This paper defines the entropy generation number and obtains the analytic expressions of entropy generation number for tubular indirect evaporative cooler according to the non - equilibrium thermodynamic theory. The interaction between minimum entropy generation number and optimum structural parameter of the tubular indirect evaporative cooler has been studied. As a result, the research gives the orientation how to improve the thermodynamic perfection of tubular indirect evaporative cooler.
