Heat exchangers are thermal systems used extensively, have a major role in energy conservation,and prevent global warming. This paper is based on reviews of scientific work and provides astate-of-the-art review of the second law of thermodynamic analysis of heat exchangers. Thisresearch presents the effect of using nanofluids on the operating conditions of different types ofheat exchangers from the second law of thermodynamic point of view. In this research, thenanofluids' effect on the exergy efficiency, entropy generation, and Irriversibilities of the heatexchangers is presented.
