Claim 2:
3. The electric vehicle cooling system of claim 2, further comprising:
a first outflow pipe configured to allow cooling water cooled by one of the pair of second radiators to flow out to a side of the autonomous driving control device, and a first inflow pipe configured to allow the cooling water, which has flowed from the side of the autonomous driving control device, to flow into the one of the pair of second radiators, both of the first outflow pipe and the first inflow pipe being connected to the one of the pair of second radiators;
a second outflow pipe configured to allow the cooling water cooled by the other of the pair of second radiators to flow out to the side of the autonomous driving control device, and a second inflow pipe configured to allow the cooling water, which has flowed from the side of the autonomous driving control device, to flow into the other of the pair of second radiators, both of the second outflow pipe and the second inflow pipe being connected to the other of the pair of second radiators; and
a flow path switching section that, in a state in which a first heat exchange is permitted between the one of the pair of second radiators and the autonomous driving control device and a second heat exchange is permitted between the other of the pair of second radiators and the autonomous driving control device, is configured to permit a first connection between the first outflow pipe and the second outflow pipe and to permit a second connection between the first inflow pipe and the second inflow pipe, and in a state in which one of the first heat exchange or the second heat exchange is prevented, the flow path switching section is configured to prevent the first connection and the second connection and to prevent inflow and outflow of the cooling water to and from a side of the second radiator configuring the prevented heat exchange.
