The present invention relates to a transaxle-integrated cooling circulation system. The transaxle-integrated cooling circulation system includes: a drive motor; an inverter disposed on one surface of the drive motor and electrically connected to the drive motor; a speed reducer including a first drive shaft connected to a rotary shaft of the drive motor and a driven shaft having a different RPM from the drive shaft; a first circulation channel extending to allow a lubricating fluid in the speed reducer to make contact with the drive motor; a second circulation channel which is connected to the first circulation channel and passes through a contact surface between the drive motor and the inverter; and a third circulation channel which is connected to the second circulation channel and introduces the lubricating fluid into the speed reducer again. According to the present invention, it is possible to reduce the occurrence of failures of the motor and the inverter and improve the performance of the transaxle-integrated cooling circulation system.
