Some embodiments of this application are described in detail. The following embodiments and features of the embodiments may be combined with each other without conflict.

Referring to FIG. 1 , an embodiment of the present application provides a power device 100 , including a motor 1 , a driver 2 , an inner circulation component 4 and an outer circulation component 5 . Motor 1 is used to output rotational torque. The driver 2 is configured on the motor 1 and is used to drive the motor 1 to run. The internal circulation component 4 is disposed on the motor 1 and is provided with internal coolant thermally coupled to the motor 1 and the driver 2 . The internal circulation component 4 is used to drive under the rotation torque of the motor 1 The internal cooling liquid circulates. The outer circulation assembly 5 is disposed on the motor 1 and is thermally coupled with the inner circulation assembly 4. The outer circulation assembly 5 is used to receive external cooling liquid and drive the outer circulation assembly under the rotation torque of the motor 1. The coolant flows, taking away heat from the inner coolant.

In this way, the motor 1, the driver 2, the inner circulation component 4 and the outer circulation component 5 are integrated together. The rotational torque output by the motor 1 drives the inner circulation component 4 and the outer circulation component 5 to operate, taking away the heat generated by the motor 1 and the driver 2. . The inner circulation component 4 and the outer circulation component 5 integrated on the motor 1 occupy less space and can be adapted to situations where the installation space is limited. In addition, the integration of the motor 1, driver 2, internal circulation component 4 and external circulation component 5 can also reduce the use of connecting pipelines and effectively reduce the risk of pipeline leakage.

In the embodiment of the present application, the driver 2 includes but is not limited to a circuit board, a controller and other structures, and can be integrated into the motor 1 to drive the motor 1 to start or stop, or adjust the speed, rotation direction, etc. of the motor 1 .

The embodiments of the present application are not limited to the manner in which the driver 2 includes the above-mentioned controller. Any electronic control terminal module that can realize driving and information interaction functions and is integrated into the motor can be an embodiment of the present application.

The power device according to the embodiment of the present application is exemplified by taking an inboard engine applied to a ship. Of course, in other embodiments, the power device may also be a pod propeller used in sailboats, and the power device may also be an outboard motor used in fishing boats.

It can be understood that the internal circulation component 4 is configured in the motor 1 , that is, the internal circulation component 4 can be in contact with the shell of the motor 1 , or the internal circulation component 4 and the motor 1 share a shell, or it can be a part of the internal circulation component 4 Shared structure with part of motor 1. The outer circulation component 5 is configured on the motor 1, that is, the outer circulation component 5 can be in contact with the casing of the motor 1, or the outer circulation component 5 and the motor 1 share a casing, or it can be a part of the outer circulation component 5 and the motor 1. Part of the total structure.

When the power device 100 is in operation, the internal circulation component 4 receives the rotational torque of the motor 1 and converts the rotational torque of the motor 1 into internal fluid driving force. The internal fluid driving force drives the flow of the internal coolant, and the flow rate of the internal coolant is Proportional to the speed of motor 1. When the internal coolant flows in the motor 1, it absorbs the heat generated by the motor 1 through contact conduction. In addition, the internal coolant circulates in the motor 1 driven by the internal fluid driving force, maintaining the temperature balance throughout the motor 1 and reducing the local excessive temperature of the motor 1. The external circulation component 5 receives the rotational torque of the motor 1 and converts the rotational torque of the motor 1 into external fluid driving force. The external fluid driving force drives the flow of external cooling liquid. The flow rate of the external cooling liquid is proportional to the rotation speed of the motor 1. The surface of part of the outer circulation component 5 is in contact with the internal coolant, and the internal coolant conducts the heat generated by the motor 1 to the external circulation component 5 in contact with it. When the external coolant flows through the part of the outer circulation component 5 that is in contact with the internal coolant, heat is transferred from the higher-temperature internal coolant to the external circulation component 5 and is absorbed by the external coolant therein, thereby reducing the heat of the internal coolant. temperature, so that the internal coolant can continue to absorb the heat generated by motor 1. After absorbing the heat, the external coolant flows out of the motor 1 under the action of external fluid driving force, and transports the heat to external equipment or the external environment. When the motor 1 rotates at a high speed and generates a large amount of heat, the flow rate of the coolant is also fast, and the heat conduction efficiency is also fast. At the same time, the flow rate of the external coolant is also high, and the heat dissipation efficiency is high, which effectively dissipates heat to the motor 1. When the motor 1 rotates at a low speed, the heat generation is small, the flow rate of the internal coolant and the external coolant is low, and the heat dissipation energy consumption is low, thereby reducing energy consumption.

Please refer to Figures 2 and 3. The motor 1 is provided with a casing 3. The casing 3 is provided with a cavity 31. The internal coolant is used to circulate in the cavity 31 and interact with the cavity 31. Chassis 3 thermally coupled.

The contact area between the coolant and the casing 3. Part of the outer circulation assembly 5 is disposed in one of the larger cavities 31 . When the internal cooling liquid flows through the cavity 31 where the outer circulation assembly 5 is located, it contacts the surface of the outer circulation assembly 5 , so that the outer circulation assembly 5 absorbs the internal cooling. The external cooling liquid flowing in the external circulation component 5 absorbs the heat of the internal cooling liquid through the heat transfer medium, and finally the external cooling liquid takes away the heat. It can be understood that in other embodiments, some of the outer circulation components 5 can be disposed in multiple cavities 31 respectively, which is beneficial to increasing the contact area between the outer circulation component 5 and the internal coolant and improving heat dissipation efficiency.

As a possible implementation, part of the external circulation assembly 5 is disposed in the cavity 31 of the motor 1 close to the driver 2 so that the internal coolant in the cavity 31 can absorb both the heat of the motor 1 and the driver 2 of heat, and facilitates the external circulation component 5 to quickly conduct away the heat of the internal coolant in the cavity 31, thereby giving priority to heat dissipation in the places where the heat of the motor 1 and the driver 2 is relatively concentrated.

In one embodiment, as shown in FIG. 3 , the casing 3 is also provided with a rotating shaft cavity 32 separated from the cavity 31 , and the motor 1 is provided with a stator 11 accommodated in the rotating shaft cavity 32 and The rotor 12 is also provided with a rotating shaft 13 fixed to the rotor 12. One end of the rotating shaft 13 is used to drive the propeller to rotate, and the other end is used to output rotational torque to the inner circulation assembly 4 and the outer circulation assembly 5. .

Under the action of the rotational torque output by the rotating shaft 13, the internal cooling liquid is driven to circulate in the multiple cavities 31, which can take away the heat generated in the rotating shaft cavity 32. .

In this way, while one end of the motor 1 serves as a work output, the other end also provides power for the inner circulation component 4 and the outer circulation component 5, outputting torque in both directions, realizing efficient use of the energy of the motor 1, making the system compact and highly integrated. , greatly improving the space utilization of the entire body structure. In addition, this structure only uses transmission pipelines in the cooling process of the external circulation component 5, and the number is small, which reduces the risk of pipeline leakage to a great extent.

The rotor 12 rotates, driving the rotating shaft 13 to rotate. The rotating shaft 13 rotates, driving part of the internal circulation component 4 to rotate. The rotating part of the internal circulation component 4 converts the rotational torque into an internal fluid driving force that drives the internal coolant to flow, thereby driving the internal coolant. flows in cavity 31. When the rotating shaft 13 rotates, it can also drive part of the outer circulation component 5 to rotate. The rotating part of the outer circulation component 5 converts the rotational torque into an external fluid driving force that drives the flow of the external coolant, thereby driving the flow of the external coolant.

When the motor 1 is working, heat is conducted from the stator 11 and the rotor 12 to the shell between the cavity 31 and the rotating shaft cavity 32 through the medium of the rotating shaft cavity 32, and is conducted through the shell to the internal cooling in the cavity 31 that is in contact with the shell. Then, when the internal coolant flows through the cavity 31 provided with a portion of the external circulation component 5, it contacts the surface of the external circulation component 5. The temperature of the external coolant flowing in the external circulation component 5 is lower than the temperature of the internal coolant after absorbing heat. , heat is transferred from the internal coolant to the external coolant in the external circulation component 5, and then the external circulation component 5 drives the external coolant to carry heat out of the motor 1, and finally conducts the heat generated by the motor 1 to external equipment or the external environment.

The cavity 31 is completely isolated from the rotating shaft cavity 32, and the internal cooling liquid is water. The internal cooling liquid will not enter the rotating shaft cavity 32 and cause damage to the stator and rotor. The internal coolant can also be a non-conductive liquid, which is beneficial to improving the safety of the motor 1 and reducing the occurrence of leakage problems. Of course, in other embodiments, if the internal coolant is thermally conductive lubricating oil, the cavity 31 and the rotating shaft cavity 32 can also be connected.
