[0037] In one embodiment, a heat dissipation cavity may be provided in the packaging shell 01, and a heat exchange medium may be filled in the heat dissipation cavity, and the heat of the packaging shell 01 may be absorbed by the heat exchange medium to enhance the heat dissipation effect.

[0038] Based on the technical solution of the embodiment of the present application, during the operation of the device, the power board 04 and the battery pack will generate a large amount of heat. By installing an internal spoiler component 02 on the battery assembly and the power board 04, the convection heat exchange between the battery assembly, the power board 04 and the internal gas is strengthened, and the heat is quickly dissipated to the internal gas; the internal gas flows inside the device driven by the spoiler component 02, flows through the battery assembly and the power board 04 in turn, and takes away the heat generated by the battery assembly and the power board 04. Then it flows through the internal heat dissipation fins 05 through a specific air duct, and the absorbed heat is transferred to the internal heat dissipation fins 05 and the packaging shell 01, and the packaging shell 01 dissipates the heat to the external environment; finally, the internal gas that has released the heat flows through the battery assembly and the power board 04 again under the action of the suction of the spoiler component 02, and participates in the heat exchange process; the internal heat dissipation fins 05 can increase the heat exchange area between the inner surface of the packaging shell 01 and the gas, and improve the heat exchange efficiency with the internal gas. The internal heat dissipation fins 05 can transfer the absorbed heat to the packaging shell 01 through heat conduction. The package shell 01 dissipates heat to the outside air through natural heat dissipation. In addition, since the package shell 01 has good airtightness, the package shell 01 can be connected to a liquid cooling device, such as covering a liquid cooling pipeline to absorb heat, thereby enhancing the heat dissipation effect, or the package shell 01 can be directly cooled by water.
