To improve cooling performance in a cooling circuit in which a plurality of heating sources are serially arranged.SOLUTION: In a cooling device 1 of a vehicle capable of switching a cooling liquid circulation direction by switching a rotation direction of an electric pump 11 in a cooling circuit 10 in which a plurality of heating sources 31 and 32 are serially arranged so as to distribute the cooling liquid, an ECU 20 includes switching means for switching a rotation direction of the electric pump 11 when the temperature of the object heating source located on the most downstream side with an outflow port of a radiator 12 as a reference in a current circulation direction of the cooling liquid of the plurality of heating sources 31 and 32 can be determined to be in a predetermined high-temperature state.SELECTED DRAWING: Figure 1
【課題】複数の発熱源が直列に配置された冷却回路内についての冷却性能を向上させること。【解決手段】複数の発熱源31,32が冷却液を流通可能に直列に配置された冷却回路10内で、電動ポンプ11の回転方向を切り替えることにより冷却液の循環方向を切り替えることができる車両の冷却装置1において、ECU20は、複数の発熱源31,32のうち、現在の冷却液の循環方向で放熱器12の流出口を基準にして最も下流側に位置する対象発熱源の温度が所定の高温状態にあると判断できる場合に、電動ポンプ11の回転方向を切り替える切替手段を備える。【選択図】図1
