COOLING SYSTEM

A cooling system includes a motor, a power converter, a flow path through which a cooling fluid flows to the motor and the power converter, and a switching valve that switches the flow path through which the cooling fluid flows. The flow path includes a first flow path and a second flow path that are bifurcated and rejoined, the motor is disposed in the first flow path, and the power converter is disposed in the second flow path. The switching valve is disposed at a position where the flow path branches into the first flow path and the second flow path, and is configured to be switchable the flow path through which the cooling fluid flows to the first flow path and the second flow path.
