[0085] In an embodiment of the present invention, when charging, the charging grab 3 is removed from the charging port connected to the vehicle body, and the AC power grid supplies power to the control module 9 through the main cable. The control module 9 charges the vehicle body through the sub-cable 2. The control module 9 integrates a number of electronic components. The electronic components generate heat when working. The air-cooling heat dissipation component 5 performs air cooling and heat dissipation on the charging pile body 1, accelerating the circulation of gas in the charging pile body 1 and the external cold air to achieve the heat dissipation effect. When the external cold air enters the charging pile body 1 through the dehumidification and dust-proof mechanism 8, the dehumidification and dust-proof mechanism 8 removes moisture and dust in the cold air to prevent dust and moisture from entering the charging pile body 1 with the flowing air during heat dissipation. A fin assembly 6 is provided on one side of the control module 9.

Then the coolant in the sealing cover 71 is passed into the coolant storage tank 73 through the liquid outlet pipe 75. Since the liquid outlet pipe 75 is provided with a folding end, and the folding end is at the first ventilation window 52, ​​during air cooling, when the external cold air enters the charging pile body 1 from the first ventilation window 52, ​​the coolant in the liquid outlet pipe 75 is cooled to ensure that the coolant entering the coolant storage tank 73 has been cooled.

[0105] It should be noted that the connection between the liquid inlet pipe 72 and the sealing cover 71 is located at the upper end of the sealing cover 71 , and the connection between the liquid outlet pipe 75 and the sealing cover 71 is located at the lower end of the sealing cover 71 .

[0111] There are two groups of limiting components 85 , both of which are connected to the charging pile body 1 . The limiting components 85 are used to limit the dehumidification box component 82 .

While ensuring the heat dissipation effect of the charging pile body 1, the present invention also effectively ensures that dust and moisture are not easy to enter the interior of the charging pile body 1, thereby ensuring that the internal equipment and electronic and electrical components of the charging pile body 1 will not age due to heat, and also avoids accidents in which electronic and electrical components are short-circuited due to the influence of dust and moisture.

Due to the limitation of the positioning assembly 84, when the box body 821 is tilted, the dustproof assembly 83 will not be poured out together with it. Then, the new molecular sieve is placed in the box body 821, and after closing the box cover 822, the box body 821 is placed in the first installation slot 81 to complete the replacement.

At the same time, the L-shaped plate 843 compresses the spring 844, and then the dustproof screen plate 834 is pulled toward the side close to the L-shaped plate 843 through the second handle 835 until the dustproof screen plate 834 is separated from the positioning block 845, and then the second handle 835 is pulled upward, and the second handle 835 drives the dustproof screen plate 834 to move upward and separate from the second installation slot 832, and then the cleaned or new dustproof screen plate 834 is put back into the second installation slot 832 , loosen the connecting plate 842, and the L-shaped plate 843 moves to the side close to the positioning block 845 under the elastic action of the spring 844, and the L-shaped plate 843 drives the sliding rod 841 to move, and the sliding rod 841 drives the connecting plate 842 to move and reset. At the same time, the L-shaped plate 843 drives the dustproof screen plate 834 to move to the side close to the positioning block 845 until the dustproof screen plate 834 abuts against the side wall of the second mounting groove 832. At this time, the dustproof screen plate 834 is limited by the joint action of the L-shaped plate 843, the positioning block 845 and the second mounting groove 832.
