1. A vehicle heat management system applied to a vehicle to which an internal combustion engine is mounted, comprising:

  • a first circulation circuit that cools an engine body of the internal combustion engine, and in which is provided a first pump that pressure feeds coolant;

    a second circulation circuit in which are provided an exhaust heat recovery apparatus that recovers exhaust heat of the internal combustion engine, a heater core that is used for air conditioning of the vehicle, and a second pump that pressure feeds coolant;

    a communicating section that communicates together the first circulation circuit and the second circulation circuit so as to be able to mix together the coolant in the first circulation circuit and the coolant in the second circulation circuit;

    a control valve provided in the communicating section, that can be changed over between communicating together the first circulation circuit and the second circulation circuit, and preventing such communication; and

    a coolant temperature control device configured to control the control valve, so as to implement a state in which the temperature of the coolant flowing in the first circulation circuit is higher than the temperature of the coolant flowing in the second circulation circuit.
