[0020] In this embodiment, in order to solve the problem that the vent 4 cannot adjust the wind force of the branch pipe as needed, and cannot distribute it to different branch pipes as needed, the connecting rod 303 is interference fit with the first fixing hole 301 and the second fixing hole 305, and the block 304 covers the ventilation pipe 602; the block 304 rotates around the second fixing hole 305, and the block 304 on the connecting rod 303 is rotated by the rotating pin 302, so that the block 304 blocks the ventilation pipe 602 of the air evacuation device 6, so that the air volume delivered to different ventilation pipes 602 can be adjusted as needed, so that heat can be dissipated to different places as needed.

[0021] In this embodiment, in order to solve the problem that the heat dissipation device cannot dissipate heat for the battery core 2, and some places are far away from the vent 4, resulting in a poor heat dissipation effect, the ventilation pipe 602 is transported to the gap between the battery core 2 and the battery shell 1 through the connecting pipe, and the fixed baffle 601 is fixed to the fixing frame 9 through the fastening bolts 604 and the connecting plate 605; the ventilation pipe 602 and the fixing frame 9 are interconnected, and the connecting pipe on the ventilation pipe 602 is fixed to the inner wall of the battery shell 1 through a clamp, and the wind is input to the specified position through the ventilation pipe 602 and the connecting pipe, which is more conducive to the heat dissipation of the vehicle battery and more practical.
