Abstract The influences of series schemes on the heat exchanger system are investigated using matrix analysis method in the present work. The performance of heat exchanger system can be improved by arranging the series schemes without an obvious increase of pressure drop or heat transfer area. The matrix analysis indicates that the series scheme has important effect on the parameter distribution over the heat exchanger system. The heat transfer can be enhanced by improving the distributed coordination between heat transfer coefficient and temperature difference besides increasing their values. The better distributed coordination between heat transfer coefficient and temperature difference corresponds to the better uniformity of heat transfer rate over the heat exchanger system, which is favorable to safety running of system. The matching performance improvement between the entransies of hot and cold fluids could lead to the better distributed uniformity of entransy dissipation over the heat exchanger system, which results in the reduction of the total entransy dissipation finally. The present work might provide a new approach to the optimization and layout of heat exchanger system for the fluids with drastic changes of properties.

换热系统串联方案的协调分布分析

摘要 本文采用矩阵分析方法研究了串联方案对换热器系统的影响。串联方案可以提高换热系统的性能，而不会明显增加压降或传热面积。矩阵分析表明，串联方案对换热器系统的参数分布有重要影响。除了提高传热系数和温差的值外，还可以通过改善传热系数和温差之间的分布协调来增强传热。传热系数与温差分布协调性越好，换热系统传热速率的均匀性越好，有利于系统的安全运行。热流体和冷流体之间的火积匹配性能的提高可以导致换热器系统上更好的火积耗散分布均匀性，最终导致总火积耗散的减少。目前的工作可能为性能急剧变化的流体的换热器系统的优化和布局提供一种新方法。
