[0002] At present, the dust-proof and heat dissipation structures of most electric vehicle DC charging piles, power control cabinets, energy storage cabinets and other products on the market are all composed of three parts: the door frames with louvers on both sides, the central heat dissipation channel, and the internal heat dissipation fans. The structure of the door frame with louvers is shown in Figure 1 , which includes door frame g, louvers f, longitudinal louver welding frame e, transverse louver welding frame f, foam pressing plate fixing frame c, foam b, and foam pressing plate a. Among them, the louvers f, longitudinal louver welding frame e, transverse louver welding frame f, foam pressing plate fixing frame c, and foam pressing plate a are all obtained through processes such as steel plate bending, welding, and spraying. It is time-consuming and laborious, not conducive to large-scale production, and the surface is prone to rust, which is not conducive to installation and replacement in the later stage;

[0026] A heat dissipation structure of an intelligent charging pile, as shown in Figures 2 - 6 , which includes a charging cabinet body 10. A heat dissipation channel 20 is arranged inside the charging cabinet body 10, and through mounting surfaces 21 are arranged on both sides of the heat dissipation channel 20; the heat dissipation structure of the intelligent charging pile further includes two groups of shutter door frames 30 and at least one heat dissipation fan 40;

[0027] Two groups of shutter door frames 30 are respectively fixedly installed on the corresponding through installation surfaces 21. Each group of shutter door frames 30 includes a door frame 50, a plastic shutter 60, a foam 70, and a foam pressing plate 80. One side edge of the door frame 50 is installed on the corresponding side edge of the through installation surface 21 of the charging cabinet 10 through a hinge. Heat dissipation holes 51 are arranged on the surface of the central area of the door frame 50. The plastic shutter 60 covers the heat dissipation holes 51 in the central area of the door frame 50. The surface of the plastic shutter 60 away from the inner wall of the door frame is covered with the foam 70. The foam pressing plate 80 presses the outer contour edge 71 of the foam 70 against the outer frame 61 of the plastic shutter 60. The whole formed by the plastic shutter 60, the foam 70, and the foam pressing plate 80 is fixedly installed on the corresponding inner wall of the door frame 50. The shutters 62 and the outer frame 61 of the plastic shutter 60 are integrally injection molded.

[0028] During specific implementation, the angle of the shutters 62 of the plastic shutter 60 is fixedly set and does not need to be set to be adjustable.

[0029] During specific implementation, a number of positioning screw holes 52 are arranged on the edge of the inner wall of the door frame 50. Each positioning screw hole 52 corresponds to an installation bolt 90. The outer frame 61 of the plastic shutter 60 is provided with installation holes corresponding to the positions of the positioning screw holes 52. The outer contour edge 71 of the foam 70 is provided with installation holes corresponding to the positions of the positioning screw holes 52.

[0032] During specific implementation, the plastic shutter 60 is directly injection molded, and the fire resistance and heat resistance are improved by adding auxiliary materials; the injection molding process can ensure the accuracy of the component dimensions; the weight of the component can be reduced. The density of the plastic is 1.2 g / cm 2 , while the density of steel is 7.85 g / cm 2 ; it reduces the structural components, can be mass-produced, saves the installation time of the production line, improves the efficiency of workers, and thus reduces the cost.

[0033] Its working principle is as follows. The shutter and the outer frame of the plastic shutter are integrally injection-molded. After the plastic shutter, the foam, and the foam pressing plate are combined into one, they can be directly fixed on the inner wall of the door frame to complete the assembly of the door frame with a shutter, which makes the assembly of the door frame with a shutter fast and convenient, and ensures quick replacement in the future.
