Title:
POWER UNIT, HEAT DISSIPATION CIRCULATION SYSTEM, AND DEVICE MOVABLE IN WATER BODY
Document Type and Number:
WIPO Patent Application WO/2024/050793
Kind Code:
A1
Abstract:
The present application provides a power unit, a heat dissipation circulation system, and a device movable in a water body. The power unit comprises a motor, a driver, an internal circulation assembly, and an external circulation assembly. The motor is used for outputting rotational torque. The driver is configured on the motor and is used for driving the motor to operate. The internal circulation assembly is configured on the motor and is provided with an internal cooling fluid thermally coupled to the motor and the driver, and the internal circulation assembly is used for driving, under the action of the rotational torque of the motor, the internal cooling fluid to circularly flow. The external circulation assembly is configured on the motor and is thermally coupled to the internal circulation assembly, and the external circulation assembly is used for receiving an external cooling fluid and driving, under the action of the rotational torque of the motor, the external cooling fluid to flow to take away heat of the internal cooling fluid. The motor, the driver, the internal circulation assembly and the external circulation assembly are integrated; the rotational torque output by the motor drives the internal circulation assembly and the external circulation assembly to operate to take away heat generated by the motor and the driver; and the structure of a cooling system is simplified.
