Effect of Nanofluids on Heat Pipe Thermal Performance: A Review of the Recent Literature

Normally conventional fluids are used in heat pipes to remove the heat based on a temperature range for its particular operating conditions [1] (see Fig.2). The addition of the nano particles to the base fluid is one of the significant issues to enhance the heat transfer of heat pipes. The purpose of this review is to summarize the research done on heat pipes using nanofluids as working fluids in recent years (2012 to 2013). This review article provides additional information for the design of heat pipes with optimum conditions regarding the heat transfer characteristics of nanofluids in heat pipes. Moreover, this paper identifies several important issues that should be considered further in future works
