Heat exchangers are used in various industries such as power plants, air conditioning and oil and gas industries. The main role in converters is the responsibility of the fluid flowing in them. Optimizing the heat transfer properties of these fluids can be an important step towards optimizing the performance of the heat exchanger and ultimately increasing productivity in industries. The use of advanced and optimized cooling systems is inevitable. Nowadays, the issue of reducing or optimizing energy consumption is very important due to the depletion of fossil fuel resources. For this purpose, the designers of heat exchangers believe that it is possible to significantly reduce the energy consumption of this equipment by making small changes. The optimization of the existing heat transfer systems is usually done by increasing their surface, which always increases the volume and size of these devices. Therefore, to overcome this problem, new and effective coolants are needed, and nanofluids have been proposed as a new solution in this field. Due to the significant increase in thermal properties, nanofluids have attracted the attention of many scientists in recent years. In this article, the properties of nanofluids have been investigated as one of the most suitable and strongest choices in the field of cooling fluids, which the investigations showed, the exceptional properties of nanofluids include more thermal conductivity than normal suspensions, non-linear relationship between conductivity and concentration of solid materials and There is a strong dependence of conductivity on temperature and a strong increase in heat flux in the boiling zone.
