Abstract
The disclosed technology relates to a heat transfer system and heat transfer method employing a dielectric oleaginous heat transfer fluid. In particular, the technology relates to a dielectric oleaginous heat transfer fluid with low electrical conductivity, low flammability, and low freeze point that provides excellent peak temperature reduction in a heat transfer system, such as that for cooling a power system of an electric vehicles.
