The second fan rotates in reverse, and the hot air discharged by the second fan will pass through the second filter screen. The hot air blows away the dust accumulated on the second filter screen to clean the second filter screen. When too much dust accumulates on the first filter screen, the first fan rotates in reverse and the second fan rotates forward, allowing the second filter screen to filter the cold air and the hot air to clean the first filter screen, realizing cyclic alternation to clean the first filter screen and the second filter screen, and avoiding the influence of dust accumulation on the heat dissipation efficiency of this charging pile.

[0018] Since the first fan and the second fan are respectively located at the top of the first air duct and the top of the second air duct, the cold air enters the cabinet from the first fan, and the cold air will flow sequentially along the first air duct, the third air duct and the second air duct. After cooling the electronic components, it is converted into hot air and discharged from the second fan, making the flow of the cold air smoother. Moreover, the cold air can contact each electronic component and cool it, and the hot air can also be discharged in time, further improving the heat dissipation efficiency of this charging pile.

[0040] Please refer to Figures 1 - 5 。

[0041] This device has two operating modes to achieve cyclic and alternating cleaning of the first filter screen 21 and the second filter screen 31;

[0042] The first operating mode of this device:

[0043] When excessive dust accumulates on the second filter screen 31, affecting the efficiency of the second filter screen 31 in passing cold air, the first fan 2 starts to rotate forward. The cold air inhaled by the first fan 2 from the outside of the cabinet body 1 will pass through the first filter screen 21. The first filter screen 21 intercepts the dust in the cold air on the first filter screen 21, thereby filtering the cold air entering the cabinet body 1. After the cold air enters the cabinet body 1, it flows through the first air duct, the third air duct, and the second air duct in sequence. During the flow of the cold air, it contacts the electronic components 11 and cools them. After the cold air cools the electronic components 11, it is converted into hot air. The second fan 3 starts to rotate in reverse. The second fan 3 extracts the hot air in the second air duct, increasing the flow rate of the cold air and the hot air in the first air duct, the third air duct, and the second air duct, and improving the efficiency of cooling the electronic components 11. When the second fan 3 extracts the hot air in the second air duct and discharges it outside the cabinet body 1, the hot air will pass through the second filter screen 31, and the hot air blows away the dust accumulated on the second filter screen 31, realizing the cleaning of the second filter screen 31.

[0044] The output shaft of the first motor 63 drives the air duct 62 to rotate a certain angle in the air box 61 through the transmission belt 631, so that the notch 621 of the air duct 62 rotates close to the air outlet 612 adjacent to the second air duct, allowing the hot air in the fourth air duct to be introduced into the second air duct and discharged outside the cabinet body 1 by the second fan 3.

[0045] The second operating mode of this device:

[0046] When excessive dust accumulates on the first filter screen 21, affecting the efficiency of the first filter screen 21 in passing cold air, the second fan 3 starts to rotate forward. The cold air inhaled by the second fan 3 from the outside of the cabinet body 1 will pass through the second filter screen 31. The second filter screen 31 intercepts the dust in the cold air on the second filter screen 31, thereby filtering the cold air entering the cabinet body 1. After the cold air enters the cabinet body 1, it flows through the second air duct, the third air duct, and the first air duct in sequence. During the flow of the cold air, it contacts the electronic components 11 and cools them. After the cold air cools the electronic components 11, it is converted into hot air. The first fan 2 starts to rotate in reverse. The first fan 2 extracts the hot air in the first air duct, increasing the flow rate of the cold air and the hot air in the second air duct, the third air duct, and the first air duct, and improving the efficiency of cooling the electronic components 11. When the first fan 2 extracts the hot air in the first air duct and discharges it outside the cabinet body 1, the hot air will pass through the first filter screen 21, and the hot air blows away the dust accumulated on the first filter screen 21, realizing the cleaning of the first filter screen 21.

[0047] The output shaft of the first motor 63 drives the air duct 62 to rotate a certain angle in the air box 61 through the transmission belt 631, so that the notch 621 of the air duct 62 rotates close to the air outlet 612 adjacent to the first air duct, allowing the hot air in the fourth air duct to be introduced into the first air duct and discharged outside the cabinet body 1 by the first fan 2.

[0048] The utility model provides a charging pile with an efficient cooling and heat dissipation effect. When the first fan rotates forward, the cold air inhaled by the first fan from the outside of the cabinet will pass through the first filter screen. The first filter screen intercepts the dust in the cold air, thereby filtering the cold air entering the cabinet. The cold air contacts the electronic components in the cabinet and conducts heat exchange. After cooling the electronic components, the cold air is converted into hot air. The second fan rotates in reverse, and the hot air discharged by the second fan will pass through the second filter screen. The hot air blows away the dust accumulated on the second filter screen to clean the second filter screen. When too much dust accumulates on the first filter screen, the first fan rotates in reverse and the second fan rotates forward, allowing the second filter screen to filter the cold air and the hot air to clean the first filter screen, realizing the cyclic alternation of cleaning the first filter screen and the second filter screen to avoid the accumulation of dust from affecting the heat dissipation efficiency of this charging pile.

[0049] Since the first fan and the second fan are respectively located at the top of the first air duct and the top of the second air duct, the cold air enters the cabinet from the first fan, and the cold air will flow sequentially along the first air duct, the third air duct and the second air duct. After cooling the electronic components, it is converted into hot air and discharged from the second fan, making the flow of the cold air smoother. Moreover, the cold air can contact each electronic component and cool it, and the hot air can also be discharged in time, further improving the heat dissipation efficiency of this charging pile.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
