A cooling system for an in-wheel motor vehicle is provided with: a first coolant flow path provided in an in-wheel motor mounted on a wheel of the vehicle; a second coolant flow path provided in an inverter that drives and controls the hub motor; a heat sink through which a coolant for cooling the inverter and the hub motor passes to dissipate heat of the coolant; a coolant circulation line connecting the first coolant flow path and the second coolant flow path with the radiator; a portion of the coolant circulation line on the upstream side of the inverter based on the coolant circulation path is branched into a secondary coolant circulation line connected to the inverter and a water pump disposed on the coolant circulation line and pumping the coolant; coolant pumped by the water pumps is distributed and passes in parallel through the inverters through the secondary coolant circulation lines.

    本发明提供一种用于轮毂电机车辆的冷却系统,具备:第一冷却剂流路,设置在搭载于车辆的车轮的轮毂电机中;第二冷却剂流路,设置在对所述轮毂电机进行驱动控制的逆变器中;散热器,使冷却所述逆变器及所述轮毂电机的冷却剂通过,使所述冷却剂散热;冷却剂循环线路,连接所述第一冷却剂流路及所述第二冷却剂流路与所述散热器;上述冷却剂循环线路中的基于冷却剂循环路径的位于上述逆变器的上游侧的部分,分支成分别与上述逆变器连接的二次冷却剂循环线路和配置在上述冷却剂循环线路上并对上述冷却剂进行泵送的水泵;由这些水泵泵送的冷却剂被分配并且通过这些二次冷却剂循环线路并行地通过这些逆变器。
