Abstract

Due to their favorable thermophysical and environmental properties HFE7100 and HFE7500 are extensively applied as heat transfer fluids in semiconductor industry and cleaning solvents in electronic components. Thermal conductivity of HFE7100 and HFE7500 under atmospheric pressure was measured by a transient hot-wire technique

as well as their liquid viscosity and surface tension by the surface light scattering (SLS) method. Thermal conductivity and liquid viscosity were correlated with temperature as polynomial functions. The average absolute deviations between correlations and experimental data of thermal conductivity and liquid viscosity are 0.37% and 1.19% for HFE7100

and 0.08% and 1.10% for HFE7500

respectively. A modified correlation based on van der Waals was used for that of surface tension as a function of temperature

by which the average absolute deviations of surface tension are 0.03 and 0.02 mN·m-1 for HFE7100 and HFE7500

respectively. In this study

the experimental and correlation data of conductivity

viscosity and surface tension can be supportive for engineering application.
