Heat exchangers are important devices for thermal systems in many industrial fields. In order to improve efficiency of commonly used shell and tube heat exchangers, nanofluids are used as coolants due to unique characteristics. This paper reviews and summarizes rescent investigations conducted on use of nanofluids in shell and tube heat exchangers with different concentrations with base fluids. Challenges and opportunities for future research are presented and discussed. The Shell and Tube Heat Exchangers are the most commonly used in for industrial application due to its numerous beneficial application. Device is used for transferring of internal thermal energy between the two or more fluids/ gases at different temperature levels. In heat exchangers the fluids are segregated by the heat transfer surface and ideally they do not mix with each other. Nanofluids are nanoparticles suspended in base fluids. E.g. CuO in water with size of nanoparticles in the range 1-100 nm. Due to thermophysical properties coefficient of heat transfer with nanofluids is more than that of base fluids.
