VEHICLE COOLING SYSTEM STRUCTURE

WIPO Patent Application WO/2024/023942

A1

Provided is a vehicle cooling system structure for an electric vehicle comprising: an internal combustion engine; a drive device including an electric motor as a travel drive source; a battery that is charged with electric power generated by driving the internal combustion engine; a first coolant pipe connected to the drive device; a second coolant pipe connected to the battery; and a radiator that is disposed in the front part of the vehicle to dissipate heat of the coolant flowing through the first coolant pipe and the second coolant pipe. In this vehicle cooling system structure, the internal combustion engine and the drive device are disposed in parallel respectively in one side region and the other side region different from the one side region in the vehicle width direction of the electric vehicle. The second coolant pipe extends from the radiator and is connected to the battery via a drive device outside region in the other side region. In particular, the drive device outside region is a region located outside the drive device in the vehicle width direction and on the side opposite to the internal combustion engine.
