COOLING SYSTEM FOR IN-WHEEL MOTOR VEHICLES

An embodiment cooling system for in-wheel motor vehicles includes first coolant flow paths provided in in-wheel motors mounted in wheels of a vehicle, second coolant flow paths provided in inverters configured to drive and control the in-wheel motors, a radiator configured to pass therethrough a coolant having cooled the inverters and the in-wheel motors to dissipate heat from the coolant, a coolant circulation line connecting the first and second coolant flow paths and the radiator, wherein a portion of the coolant circulation line located at upstream sides of the inverters based on a coolant circulation path is branched off into secondary coolant circulation lines respectively connected to the inverters, and water pumps disposed on the coolant circulation line and configured to pump the coolant, wherein the coolant pumped by the water pumps is distributed and passes through the inverters in parallel by way of the secondary coolant circulation lines.
