Abstract

In this paper, the effect on the thermal efficiency enhancement of a heat pipe using SiO 2 -water nanoﬂuid on different operating states was investigated. SiO 2 -water nanofluids with mass concentrations of 0.1% ~ 2.0% have been prepared with the average size of 10nm, 30nm, 50nm, 70nm, respectively. Heat transfer characteristics of the heat pipe including wall temperature distribution, heat transfer coefficient and thermal resistance have been investigated, which showed excellent properties.
