| Abstract: | Based on the second law of thermodynamics, the four kinds of exergy efficiency of heat exchangers are analysed and the effects of heat capacity ratio of fluids( R ), heat transfer units number( N tu ) and flow pattern on the exergy efficiency are discussed. The results in this paper provide the reference for the analysis and evaluation of the thermodynamic performance of heat exchangers. |
