  • Publication number: 20230365850
    Abstract: Branched paraffins formed as a hydrogenated reaction product of one or more linear alpha olefins (LAOs) oligomerized with a BF3 catalyst system and comprising at least about 90 wt. % branched paraffin dimers may have advantageous heat transfer properties. Heat transfer fluids comprising the branched paraffins may be placed in contact with a heat- generating component, such as those found in electric vehicles, battery systems, and other locations in need of thermal management. Branched paraffin dimers formed from one or more LAOs having about 8 to about 12 carbon atoms may collectively have a Mouromtseff Number ranging from about 10,000 to about 16,000 kg/(s2.2.m0.6.K) at 80° C., a thermal conductivity at 80° C. of about 0.125 W/m.K or higher, and a flash point of about 140° C. or higher.

  • Publication number: 20220267658
    Abstract: Methyl paraffins formed by hydrogenating one or more LAO dimers comprising a vinylidene moiety or a trisubstituted olefin moiety may have advantageous heat transfer properties, particularly when incorporated within an electric vehicle. For example, methyl paraffins produced upon hydrogenating LAO dimers formed from one or more C6-C12 LAOS, particularly in the presence of a Hf metallocene catalyst system, may contain 12-24 carbon atoms, and collectively have a flash point of about 130° C. or above, a pour point of about ?42° C. or lower, a thermal conductivity at 80° C. of about 0.165 W/m·K or higher, and a Mouromtseff number ranging from about 17,000 to about 27,000 kg/(s2.2·m0.6·K) at 80° C. Heat transfer fluids comprising such methyl paraffins may be placed in contact with a heat-generating component, such as a battery and/or motor of an electric vehicle, or within a similar type of battery system, including immersive configurations for a battery.

  • Publication number: 20210040369
    Abstract: This disclosure relates to heat transfer fluids for use in an apparatus having a heat transfer system. In one embodiment, the heat transfer fluids have at least one Group IV base oil, as a major component; at least one phenolic antioxidant, as a minor component; and optionally an aminic antioxidant in an amount less than about 0.25 weight percent, based on the total weight of the heat transfer fluid. In another embodiment, the heat transfer fluids have at least one Group V base oil, as a major component; and a mixture of at least two antioxidants, as a minor component. The at least one Group IV base oil and the at least one Group V base oil have a kinematic viscosity (KV100) from about 0.5 cSt to about 12 cSt at 100° C. The mixture of at least two antioxidants has a phenolic antioxidant and an aminic antioxidant. This disclosure further relates to methods for improving thermal-oxidative stability of a heat transfer fluid used in an apparatus having a heat transfer system.
