To suppress electric power consumption during warming-up of an internal combustion engine.SOLUTION: In a first circulation circuit 20, an internal combustion engine 24 is provided on the downstream side of a first pump 22 and a first radiator 26 is provided on the upstream side. In a second circulation circuit 40, a supercharger 46 is provided on the upstream side of a second pump 42 and a second radiator 44 is provided on the downstream side. A first connection flow passage 60 is extended from a portion between the first radiator 26 and the first pump 22 in the first circulation circuit 20 to a portion between the supercharger 46 and the second pump 42 in the second circulation circuit 40. A second connection flow passage is extended from a portion between the internal combustion engine 24 and the first radiator 26 in the first circulation circuit 20 to a portion between the supercharger 46 and the second radiator 44 in the second circulation circuit 40. When a first on-off valve 62 for opening/closing the first connection flow passage 60 is opened, a rotary valve 74 for opening/closing the second connection flow passage is opened.SELECTED DRAWING: Figure 6

    【課題】内燃機関の暖機中における消費電力を抑える。【解決手段】第1循環回路20には、第1ポンプ22よりも下流側に内燃機関24が設けられ、上流側に第1ラジエータ26が設けられている。第2循環回路40には、第2ポンプ42よりも上流側に過給機46が設けられ、下流側に第2ラジエータ44が設けられている。第1循環回路20における第1ラジエータ26と第1ポンプ22との間から、第2循環回路40における過給機46と第2ポンプ42との間へと、第1接続流路60が延びている。第1循環回路20における内燃機関24と第1ラジエータ26との間から、第2循環回路40における過給機46と第2ラジエータ44との間へと、第2接続流路が延びている。第1接続流路60を開閉する第1開閉弁62が開弁さるときには、第2接続流路を開閉する回転弁74が開弁される。【選択図】図6
