Effects of Hybrid Nanofluids on the Thermal Performance of Heat Pipe: An Experimental Investigation

Abstract

A heat pipe is an excellent heat transfer device, widely used in electronics cooling. Nanofluids have superior thermophysical properties. Researchers noticed that nanofluids are very effective working fluids as they enhanced the heat transfer characteristics of heat pipes (HPs). Mono nanofluids have their limitations regarding the applications in heat pipes. Therefore, the research community extends its work toward the application of hybrid nanofluids. In the present investigation, the authors used TiO2/H2O and (TiO2 + MWCNT)/H2O as working fluid in the HP for a wide range of power input (50–100 watts). The authors noticed the significant enhancement in the performance of HP using hybrid nanofluids. The mechanisms/causes of enhancement in the TPHP have been identified.
