A new way to enhance the heat transfer rate of heat pipe by going above the already existing heat transfer rate is the use of Nanofluids. This talks about the various researches done on heat pipes with the aid of nanofluids inside it as working fluids. The high impact of characteristics and mass concentrations of nanoparticles on the thermal behaviour and enrichment in various types of heat pipes with various base fluids under number of operating conditions have been studied. In the tested heat pipes the impact of enhancement as well as degradation is explained. A comparative study of the newly designed system with the earlier system by showing the relative degradation is mentioned.

Keywords: Nanoparticles, nanofluid, heat transfer, thermal conductivity, thermal resistance, volume concentration.
