The top cover 262 can support and limit the dustproof mesh plate 263, thereby preventing impurities in the external air from entering the cooling box 261 through the dustproof mesh plate 263.

[0042] Working principle of this embodiment: First, the heat conducting sheet 231 transfers heat to the refrigeration mechanism 1, and then the heat transfer sheet 213 transfers the heat of the air around the lithium-ion battery in the cooling box 261 to the heat conducting rod 232, and the heat conducting rod 232 transfers the heat to the heat conducting sheet 231, and the guide plate 233 transfers the heat in the surrounding air to the heat conducting rod 232, thereby cooling the surrounding air. When the air flows through the drainage drum 251, the drainage blade 252 will drive the drainage drum 251 to rotate with the flowing air, and the drainage drum 251 will drive the drainage fan 253 to rotate together, and the drainage drum 251 will drive the drainage fan 253 to rotate together. When the fan 253 rotates, it will concentrate the surrounding air and transport it to the guide plate 233. The guide plate 233 will absorb the heat in the flowing air and cool the air. Then the air will pass through the guide plate 212 and the connecting hole 222 to the guide pipe 241. Then the air will push the drainage spiral plate 243, and the drainage rotating rod 242 will drive the drainage spiral plate 243 to rotate. When the drainage spiral plate 243 rotates, it will guide the air to the holes on the drainage drum 251, so as to evenly transport the air to the surrounding lithium-ion batteries to dissipate heat from the lithium-ion batteries.
