The first pump 20 is connected between the inlet 31 and the outlet 32. The first pump 20 is used to drive the forward or reverse circulation of the first circulation circuit 30. The first circulation circuit 30 serves to cool the drive assembly 10. After the driving shaft 11 rotates, the driving shaft 11 can drive the first pump 20 and the propeller to operate, the propeller is used for providing thrust, the first pump 20 drives the first circulation loop 30 to circulate to cool the driving assembly 10, and overheating failure of the driving assembly 10 is avoided.

The heat exchanger 60 may be connected to the second circulation circuit 80. Similarly, the structural improvement of the second pump 70 integrated with the driving shaft 11 also makes the power device 100 smaller in size and convenient to install, and also avoids additional configuration of program and circuit control for the rotation speed of the second pump 70, thereby reducing the complexity of program and circuit control in the power device 100, and also avoiding additional configuration of power for the second pump 70, thereby reducing the energy consumption of the power device 100.
