1. A cooling water circuit comprising:
a heat-radiating heat exchanger in which a cooling water is heated by heat radiated from an external heat medium;
a heat-absorbing heat exchanger in which a cooling water is cooled by heat absorbed by an external heat medium; and
a first heat exchanger and a second heat exchanger in which heat is exchanged between the cooling water and outside air, wherein
when a high-temperature cooling water heated by the heat-radiating heat exchanger flows through the first heat exchanger and the second heat exchanger, the first heat exchanger and the second heat exchanger are connected in series for the cooling water to flow,
when a low-temperature cooling water cooled by the heat-absorbing heat exchanger flows through the first heat exchanger and the second heat exchanger, the first heat exchanger and the second heat exchanger are connected in parallel for the cooling water to flow,
the first heat exchanger and the second heat exchanger are arranged in a flow direction of the outside air,
the first heat exchanger is arranged downstream of the second heat exchanger in the flow direction of the outside air,
when the high-temperature cooling water heated by the heat-radiating heat exchanger flows through the first heat exchanger and the second heat exchanger, the cooling water flows in order of the first heat exchanger and the second heat exchanger,
the first heat exchanger has a first inlet/outlet and a second inlet/outlet communicated with each other,
when the high-temperature cooling water heated by the heat-radiating heat exchanger flows through the first heat exchanger, the cooling water flows in order of the first inlet/outlet and the second inlet/outlet, and
when the low-temperature cooling water cooled by the heat-absorbing heat exchanger flows through the first heat exchanger, the cooling water flows in order of the second inlet/outlet and the first inlet/outlet.
