Abstract: A vehicle thermal management system includes a vehicle driving battery that generates heat during charging and discharging and a liquid heat transfer medium that transfers the heat received from the battery. The system further includes a heat receiver that causes the heat transfer medium to receive the heat and a refrigerant heat exchanger that causes the heat transfer medium to release the heat. The heat transfer medium includes a liquid base material including water and an orthosilicic acid ester compatible with the liquid base material and does not include an ionic rust inhibitor. The orthosilicic acid ester is present, as a concentration of silicon, relative to a total mass of the heat transfer medium within a range between 1 mass ppm, inclusive, and 2000 mass ppm, inclusive or within a range between 2000 mass ppm, non-inclusive, and 10000 mass ppm, inclusive.

Abstract: A vehicle thermal management system mounted in a vehicle includes a vehicle driving battery, a liquid heat transfer medium, a heat receiver, and a radiator. The heat receiver causes the heat transfer medium to receive heat through heat exchange with the battery. The radiator causes the heat transfer medium to release the heat through heat exchange with an air outside of the vehicle. The heat transfer medium includes a liquid base material including water and an orthosilicic acid ester compatible with the liquid base material and does not include an ionic rust inhibitor. The orthosilicic acid ester is present, as a concentration of silicon, relative to a total mass of the heat transfer medium within a range between 2000 mass ppm, non-inclusive, and 10000 mass ppm, inclusive.

Abstract: A heat transfer medium for transferring heat from a vehicle driving battery that generates heat during charging and discharging includes a liquid base material, an orthosilicic acid ester compatible with the base material, and an ion adsorbent dispersed in the base material. The ion adsorbent is formed of a plurality of solid particles and adsorbs at least one of anions and cations present in the heat transfer medium.
