中文摘要	本文以并联换热器组为对象,在给定每个换热器热容量流的前提下,通过分配各换热器的热导分析了换热器组的总换热量与总(火积)耗散、总(火积)耗散热阻、各换热器(火积)耗散之和、各换热器(火积)耗散热阻之和、及各换热器(火积)耗散热阻加权之和之间的关系。结果表明:在给定每个换热器热容量流,分配热导的前提下,换热器组总换热量的极值与各换热器(火积)耗散之和的极值、各换热器(火积)耗散热阻之和的极值、及以热容量流率与换热量率的乘积作因子的各(火积)耗散热阻加权之和的极值是一致的,而与换热器组总(火积)耗散的极值及总(火积)耗散热阻的极值不一致。; For a heat exchanger group with fixed heat capacity rates,by varying the thermal conductances of each heat exchanger,this paper analyzed the inherent relations among the total heat transfer rate,the total entransy dissipation rate,the total entransy-dissipation-based thermal resistance of the heat exchanger group,and the sum of the entransy dissipation,the sum of the entransy-dissipation-based thermal resistance,the weighted sum of the entransy-dissipation-based thermal resistance of each heat exchanger.The results showed that for fixed heat capacity rates,the extremum of total heat transfer rate is the same as those of the sum of entransy dissipation rate,the sum of entransy dissipation-based thermal resistance,and the weighted sum of entransy dissipation-based thermal resistance of each the heat exchanger,whereas the extremum of total heat transfer rate does not correspond to the total entransy dissipation rate or the total entransy dissipation-based thermal resistance of the heat exchanger group.
