To provide a vehicular cooling system whose cooling capacities can be increased easily without making the system redundant, even when a high-voltage instrument that is cooled by a radiator needs equal to or more than usual cooling capacities in an emergency.SOLUTION: The vehicular cooling system comprises: a radiator mechanism 10 including a first radiator 11, a fan 13 and a second radiator 12 arranged therebetween; a first coolant circulation circuit 30 through which a first coolant cooled in the first radiator 11 circulates to perform heat-exchange with a first group instrument 50a; a second coolant circulation circuit 40 through which a second coolant cooled in the second radiator 12 circulates to perform heat-exchange with a second group instrument 50b; and a fan motor 13m that controls a rotating direction of the fan 13. The fan motor 13m switches the rotating direction of the fan 13 on the basis of temperature related information corresponding to a temperature of a high-voltage instrument group 50.SELECTED DRAWING: Figure 2

    【課題】ラジエータにより冷却される高電圧機器が緊急時において通常以上の冷却容量を必要とする場合であっても、システムを冗長化させることなく簡易にその冷却容量を増大させること。【解決手段】第1ラジエータ11、ファン13、及びその間に配置される第2ラジエータ12を含むラジエータ機構10と、第1ラジエータ11で冷却される第1冷媒が循環することにより、第1グループ機器50aと熱交換を行う第1冷媒循環回路30と、第2ラジエータ12で冷却される第2冷媒が循環することにより、第2グループ機器50bと熱交換を行う第2冷媒循環回路40と、ファン13の回転方向を制御するファンモータ13mと、を備え、ファンモータ13mは、高電圧機器群50の温度に対応する温度関連情報に基づいて、ファン13の回転方向を切り替える、車両用冷却装置。【選択図】図2
