To prevents electric leakage and a short circuit due to contact between a heat medium that adjusts a temperature by cooling/heating a device and the device such as a battery at a collision of a vehicle. Temperature adjustment passages 21 and 22 obtained by circularly connecting a battery 1, an inverter 2, a DC/DC converter 3, a traveling motor 4, which are heat generation elements as device devices, and a pump 5 that circulates the heat medium that adjusts temperatures by cooling/heating the heat generation elements, are provided. The temperature adjustment passages 21 and 22 are provided with proportional valves 9A and 9B that interrupt the flow of the heat medium and adjusts the flow volume of the heat medium, an air flow-in part 25 that introduces the air into the battery temperature adjustment passage 21, and a heat medium discharge part 24 that discharges the heat medium from the temperature adjustment passage to an outside of the vehicle. The proportional valve 9A, the air flow-in part 25, the battery 1, the pump 5, and the heat medium discharge part 24 are arranged in that order, and the proportional valve 9A is closed and an air take-in valve 103 and a heat medium discharge valve 102 are opened, and the pump 5 is stopped after being driven for a predetermined time, when the collision of the vehicle is detected or predicted. |
