Dielectric properties of environmental friendly cooling fluids

Dielectric properties of environmental friendly cooling fluids
Dielectric properties of environmental friendly cooling fluids
This paper presents an investigation of the dielectric properties of two environmental friendly cooling fluids, hydrofluoroethers and fluorinated ketone. The AC and DC dielectric response of both cooling fluids have been measured at different temperatures. The experimental results indicate that temperature is positively correlated with DC conductivity and imaginary permittivity, in contrary it is negatively correlated with real permittivity of both two fluids. Dielectric strength at 295 K has also been measured. The recorded data indicate that the dielectric strength of both hydrofluoroethers and fluorinated ketone is approximately 10 kV/mm.

Abstract

This paper presents an investigation of the dielectric properties of two environmental friendly cooling fluids, hydrofluoroethers and fluorinated ketone. The AC and DC dielectric response of both cooling fluids have been measured at different temperatures. The experimental results indicate that temperature is positively correlated with DC conductivity and imaginary permittivity, in contrary it is negatively correlated with real permittivity of both two fluids. Dielectric strength at 295 K has also been measured. The recorded data indicate that the dielectric strength of both hydrofluoroethers and fluorinated ketone is approximately 10 kV/mm.
