[0027] As briefly mentioned above, electric vehicles are becoming the transportation tool of choice for more and more people. However, the assembly and maintenance of the charging piles of the current electric vehicles are very inconvenient. For example, the air inlet assembly and the liquid cooling module of the liquid-cooled charging terminal are usually arranged inside the cabinet, which is not convenient for assembly and maintenance operation. In addition, the connection part of some liquid-cooled charging terminals is sealed by a rubber strip. During the maintenance operation, the rubber strip needs to be reinstalled or glued. After being used for many cycles, the rubber strip will age and the sealing effect will decrease.

[0028] In order to solve or at least partially solve the above-mentioned problems of the charging pile of the conventional scheme or other potential problems, embodiments of the present disclosure provide a heat dissipation device for a charging pile. In this scheme, by arranging the air inlet assembly and the drive module on the side and back side of the cabinet of the charging pile respectively, the components for cooling and the components for charging can be isolated, which greatly facilitates the assembly and maintenance of the charging pile, and then by arranging the protective cover surrounding the drive module, the sealing performance of the charging pile is ensured. In the following, the heat dissipation device for the charging pile according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings. Figures 1 to 7 The principles of the present disclosure are described.

[0029] Figure 1 A perspective view of the charging pile 1 according to an embodiment of the present disclosure is shown. Figure 2 An exploded schematic view of the charging pile 1 according to an embodiment of the present disclosure is shown. As shown in FIG. 2, the charging pile 1 includes a cabinet 10, a drive module 20, a protective cover 30, a liquid-cooled charging terminal 40, and a liquid-cooled charging terminal 50. Figure 1 and Figure 2As shown, the charging pile 1 described herein generally comprises a cabinet 11, a cabinet door 12, a charging assembly 13, and a heat dissipation device 100. The cabinet 11 serves as a support part of the entire charging pile 1, and its interior can be used to install and connect various electrical components. The cabinet door 12 is connected to the front side of the cabinet 11. The charging assembly 13 is arranged inside the cabinet 11. The cabinet door 12 can isolate the charging assembly 13 from the outside environment to ensure that the charging assembly 13 works in a sealed environment.

[0030] The heat dissipation device 100 comprises an air inlet assembly 110, a driving module 120, and a protective cover 130. The air inlet assembly 110 is arranged on the side of the cabinet to guide the cooling airflow into the interior of the cabinet 11. The driving module 120 is arranged adjacent to the back side of the cabinet 11 to drive the cooling airflow to flow through the charging assembly 13 and be discharged from the back side of the cabinet. The protective cover 130 is arranged against the back side of the cabinet 11 and surrounds the driving module 120. The protective cover is provided with a plurality of air outlets 131 to allow the cooling airflow flowing through the driving module 120 to be discharged through the plurality of air outlets 131.

[0031] It should be understood that the "front side" and "back side" herein are relative to the thickness direction X of the cabinet. For the cabinet 11, the front side can represent the side for opening the cabinet door 12, and the back side can represent the side opposite to it.

[0032] In some embodiments, the cooling airflow can be air. The driving module 120 can maximize the driving of air into the cabinet 11 through the air inlet assembly 110, thereby removing the heat generated by the charging assembly 13. In this way, the heat dissipation device 100 can provide good air flow and heat dissipation effect, thereby ensuring that the equipment in the cabinet 11 remains within an appropriate temperature range when operating. This can prevent the equipment from performance degradation, failure, or even damage due to overheating.

[0033] Figure 3 A partial exploded schematic view of the charging pile 1 according to one embodiment of the present disclosure is shown.

The driving module 120 is arranged in the recessed portion 101.

[0034] In some embodiments, as shown, Figure 2 and Figure 3As shown, the top of the drive module 120 is provided with the liquid cooling module 200. The liquid cooling module 200 includes a plurality of liquid pipes 201. The back side of the cabinet 11 is provided with a through hole 210. The plurality of liquid pipes 201 can pass through the through hole 210 into the cabinet 1 and be connected to the charging assembly 13 to perform liquid cooling on the charging assembly 13. In this way, the back side of the cabinet 11 can isolate the liquid cooling module 200 and the charging assembly 13. When maintenance work needs to be performed on the liquid cooling module 200, only the back side of the cabinet 11 needs to be operated. Without the need to open the cabinet door 12 located at the front side of the cabinet 11, the maintenance efficiency of the liquid cooling module 200 is greatly improved.
