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 introduced into an electric vehicle. For example, methyl paraffins produced when hydrogenating LAO dimers formed from one or more C6-C12 LAOs, particularly in the presence of a Hf metallocene catalyst system, may contain 12 to 24 carbon atoms, and generally have a flash point of about 130 DEG C or more, a pour point of about-42 DEG C or less, a thermal conductivity of about 0.165 W/m.K or more at 80 DEG C, and a Mouromtseff number of about 17,000 to about 27,000 kg/(s2.2. M0.6. K) at 80 DEG C. Heat transfer fluids comprising such methyl paraffins may be placed in contact with heat generating components, such as batteries and/or motors of electric vehicles, or within similar types of battery systems, including immersed configurations of batteries.
通过氢化一种或多种包含乙烯叉基结构部分或三取代烯烃结构部分的LAO二聚物形成的甲基链烷烃可具有有利的传热性质,尤其是当引入电动车辆内时。例如,在氢化由一种或多种C6‑C12LAO形成的LAO二聚物(尤其是在Hf金属茂催化剂体系存在下)时产生的甲基链烷烃可以含有12‑24个碳原子,并且总体上具有约130℃或更高的闪点、约‑42℃或更低的倾点、在80℃下约0.165W/m·K或更高的热导率和在80℃下约17,000至约27,000kg/(s2.2·m0.6·K)的Mouromtseff数。可将包含此类甲基链烷烃的传热流体放置成与生热组件(例如电动车辆的电池和/或电动机)接触,或放置在类似类型的电池系统内,包括电池的浸入式构造。
