摘　　要：基于耗散原理与经济学原理,建立了经济学,提出了一项换热器性能的经济评价指标——单位传热量的总费用η,并结合实例对螺旋板式换热器进行优化,得到其结构参数和η之间的关系,获得了最优的结构参数,可为工程上换热器的性能评价提供参考。This paper is based on the principle of entransy dissipation and exergy economics principle, estab-lished entransy economics, proposed a performance index with entransy economics of heat exchanger-the total cost of unit transfer heat η, and with the instance of optimize spiral plate heat exchanger, got its relationship between structure parameters andη, obtained the optimum structure parameters, the conclusions of this paper may provide reference for heat exchanger performance evaluation on engineering.
