Cooling structure of vehicle

Abstract

Provided is a cooling structure of a vehicle, which suppresses air stagnation in the motor when manufacturing, and improves productivity, while maintaining cooling efficiency of a motor. A cooling structure of a vehicle is equipped with a first cooling circuit () configured to cool an engine; and a second cooling circuit () configured to cool a motor () and an electric device including an inverter which connects the motor () and a power storage device, in which the first cooling circuit () has a first motor internal flow path () provided in a motor case (), the second cooling circuit () has a second motor internal flow path () provided in the motor case (), the second motor internal flow path () has a circumferential flow path () configured to allow a refrigerant (S) to flow along a circumferential direction of the motor (), an inlet pipe () configured to allow the refrigerant (S) to flow into the circumferential flow path (), and an outlet pipe () configured to discharge the refrigerant (S) from the circumferential flow path (), and the inlet pipe () is disposed to be closer to the first motor internal flow path () side than the outlet pipe ().
