The utility model discloses a heat dissipation structure of a battery pack. The heat dissipation structure comprises a shell and an electric appliance element arranged in the shell, the liquid cooling module is characterized in that an aluminum alloy heat dissipation block is further installed in the shell, the aluminum alloy heat dissipation block is of a hollow structure, one face of the outer side of the aluminum alloy heat dissipation block is a contact face used for being in contact with a corresponding liquid cooling module, one face of the inner side of the aluminum alloy heat dissipation block is in direct or indirect contact with a heating part of an electric appliance element, and the other face of the inner side of the aluminum alloy heat dissipation block is a contact face. Therefore, the heat dissipation of the heating part of the electric appliance element is realized. According to the utility model, the risk of failure of the battery pack is reduced, and the safety of the whole vehicle-mounted
