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 heat received from the battery. The system further includes a heat receiver that causes the heat transfer medium to receive heat through heat exchange with the battery and that includes a portion in contact with the heat transfer medium and made of a material containing aluminum. The system further includes a refrigerant heat exchanger that causes the heat transfer medium to release heat through heat exchange with a refrigerant and that includes a portion in contact with the heat transfer medium and made of a material containing aluminum. The heat transfer medium includes a liquid base material including water, an orthosilicic acid ester compatible with the liquid base material, and an azole derivative and has an electric insulation property.
