Because the battery pack 3, the heat conducting pad 1 and the radiator 2 are vertically arranged, and the battery pack 32 is connected with the radiator 2 through the heat conducting pad 1 from the first opening 3111 of the box 31, the battery pack 3 is positioned above the heat conducting pad 1, the radiator 2 is positioned below the heat conducting pad 1, and the battery pack 3 compresses the heat conducting pad 1 on the radiator 2, so that the battery pack 3 has certain self weight, external force can be applied from the upper direction to compress the heat conducting pad 1 by virtue of the self weight, the compressed heat conducting pad 1 can fully fill a gap between the battery pack 32 of the battery pack 3 and the radiator 2, and heat of the battery pack 32 can be better and faster transferred to the radiator 2 through the heat conducting pad 1, so that the heat dissipation effect on the battery pack 3 is improved; and because the surface of the battery pack 32 of the battery pack 3 in the vertical direction is larger than the area of the side surface of the battery pack in the horizontal direction, the heat dissipation and cooling effects on the battery pack 3 are improved again by increasing the contact area of the battery pack 32 and the heat conduction pad 1.
