Phase change dispersion, potentially a new class of heat transfer fluids

Abstract

The authors present values and an application of a phase change dispersion, where the dispersed phase change material within water changes from solid to liquid while absorbing heat and changes from liquid to solid while releasing heat at constant temperature. The phase change enthalpy increases the “apparent specific heat capacity” significantly in comparison to water. As the heat transfer takes place at constant temperature, the heat transfer fluid itself remains at constant temperature while absorbing heat. Isothermal heating and cooling of devices with a liquid is feasible.
