| 摘 要： | 本文利用熵产生数方法研究了气体和液体传热介质的顺流、逆流换热器的热力学完善性，结果表明，如给定冷、热流体的入口温度，在综合考虑传热、流动阻力和污垢的情况下，可用优化方法确定其它参数。

| Abstract: | This paper investigates the irreversibility of counterflow and paralell-flow heat exchang ers with gas or liquid as the working media by using a modified entropy generation number method. The results show that there is a number of heat transfer units and a capacity ratio for both countertflow and paralell-flow heat exchangers in which the irreversibility are minimum. |
