[0033] When the lithium battery body 103 is working, heat will be generated. At this time, the lithium battery body 103 can be cooled under the action of the heat dissipation fins 201. At the same time, since the heat dissipation fins 201 are arranged in a short middle and long manner on both sides, air circulation is convenient for dissipating heat to the heat dissipation fins 201. At the same time, the heat of the lithium battery body 103 can be exported under the action of the heat dissipation fins 2023. Since the heat dissipation fins 2023 are a wavy structure, the heat dissipation area can be increased. At the same time, the heat dissipation fins 2023 can be quickly cooled under the action of the heat dissipation fan 2022 to accelerate the heat dissipation of the heat dissipation fins 2023.
