摘　　要：基于[火积]耗散优化原理,以换热器组的[火积]耗散最小为优化目标,对具有相变的换热器组的中介流体的热容量进行优化研究.算例显示相对换热量随中介水热容量和热导率分配比的增加而先增大后减小,存在换热量极大值;同时当量热阻随中介水热容量和热导率分配比的增加而先减小后增大,存在当量热阻极小值,极值点所对应的热容量和热导率分配为最佳结果.In this paper,based on the principle of thermal dissipation optimization,the heat capacity of the intermediate fluid of heat exchanger group with phase change was optimized with the minimum of the entransy dissipation.The results showed that the relative heat transfer increases and decreased with the increase of intermediate water heat capacity and thermal conductivity distribution ratio,and there was a maximum value of heat transfer;at the same time,the equivalent thermal resistance decreased and then increased with the increase of intermediate water heat capacity and thermal conductivity distribution ratio,and there was an equivalent thermal resistance minimum value,the heat capacity and the thermal conductivity distribution corresponding to the extreme value were the best results.
