To provide a vehicle cooling system suppressing short circuit of a propulsion device while improving recovery efficiency of waste heat from the propulsion device.SOLUTION: A vehicle cooling system includes a first cooling circuit where a propulsion device is disposed and a second cooling circuit where a heating device is disposed, and can supply waste heat from the propulsion device to the heating device. The system includes: a first coolant circulating in the first cooling circuit; a second coolant circulating in the second cooling circuit; a heat exchanger performing heat exchange between the first coolant and the second coolant; and a control valve disposed in the first cooling circuit and making the first coolant after cooling the propulsion device flow into the heat exchanger when a prescribed condition is satisfied. The first coolant has insulation properties higher than that of the second coolant. The first cooling circuit is structured so that the first coolant passes through a conductive portion of the propulsion device.SELECTED DRAWING: Figure 1

    【課題】推進装置からの廃熱回収効率を向上させつつ、推進装置がショートすることを抑制できる車両の冷却システムを提供すること。【解決手段】推進装置が配置された第1の冷却回路と、暖房装置が配置された第2の冷却回路と、を備え、推進装置の廃熱を暖房装置に供給可能な車両の冷却システムであって、第1の冷却回路を循環する第1の冷却液と、第2の冷却回路を循環する第2の冷却液と、第1の冷却液と第2の冷却液との間で熱交換を行う熱交換器と、第1の冷却回路に配置されており、所定の条件が満たされた場合に、推進装置を冷却した後の第1の冷却液を、熱交換器へ流入させる制御弁と、を備え、第1の冷却液は、第2の冷却液よりも高い絶縁性を有し、第1の冷却液が推進装置の導電部位を通過するように、第1の冷却回路を構成した。【選択図】図1
