Abstract: A power assembly includes a power component and a shell. The shell includes an accommodating structure, a flow diversion structure, a liquid storage structure, a heat dissipation structure, and a heat exchange structure. The accommodating structure is filled with cooling liquid. The flow diversion structure is configured to guide a flow direction of the cooling liquid. The liquid storage structure is configured to store the cooling liquid that is guided by the flow diversion structure to enter the liquid storage structure, and to distribute the cooling liquid that enters the liquid storage structure. The heat dissipation structure is configured to receive the cooling liquid distributed by the liquid storage structure, and to transfer the cooling liquid to the power component to cool the power component. The heat exchange structure is configured to perform heat exchange and cooling on the cooling liquid in the accommodating structure.
