A circulation system includes cooling fluid, 1 st -6 th flow paths and 1 st -3 rd flow path switching devices. The first flow path includes a compartment heat exchanger. The second flow path includes a liquid temperature adjustment device and a first pump. The third flow path includes an engine cooling circuit and a second pump. The fourth flow path includes an engine heat-dissipation device. The fifth flow path includes a motor cooling circuit and a third pump. The sixth flow path includes a motor heat-dissipation device. The first, second and third flow path switching devices are respectively connected to the 1 st -4 th , 4 th -6 th , and the fifth, the sixth, the first and the second flow paths. The 1 st -3 rd flow path switching devices control the connections of the 1 st -6 th flow paths and the circulation of the cooling fluid for operating in a plurality of operation modes. |
