DETAILED DESCRIPTION
[0023] In order to more clearly and completely illustrate the technical scheme of the utility model, the utility model will be further described below in combination with the drawings.
[0024] Please refer to Figures 1-4 The utility model provides a kind of outdoor charging pile, including shell 1, same partition 2 is fixedly installed between the left and right two side inner walls of shell 1, partition 2 rear side is provided with heat dissipation mechanism 3, heat dissipation mechanism 3 includes multiple radiators 4, multiple radiators 4 are arranged in two columns, multiple radiators 4 on same vertical line constitute a heat dissipation unit, two heat dissipation units are simultaneously or intermittently operated to be used to heat dissipation to the inside of shell 1, the front side of partition 2 is provided with mounting bracket mechanism, and mounting bracket mechanism includes multiple support mechanisms 5, and multiple support mechanisms 5 are used to separate into several rectangular areas with the front side of partition 2 and are used to install internal component.
[0025] It should be noted that both sides are provided with charging ports, and each charging port is inserted with a charging gun. Such a layout can facilitate users to approach the charging pile from different directions and can simultaneously charge two vehicles. Such a setting also has a higher requirement for the heat dissipation performance of the charging pile; the two independent heat dissipation units can be flexibly controlled according to actual needs. One heat dissipation unit is enabled only when the load is low, and both heat dissipation units are enabled simultaneously when the load is high. In this way, energy is saved, and the response speed of the system is improved. Through programming control of the system, the two heat dissipation units can be used intermittently and alternately. This not only prolongs the service life of each heat dissipation unit 4, but also balances the wear degree of each part, thereby reducing the long-term operation cost.
[0026] As shown in Figure 2 and Figure 3 , the support mechanism 5 includes two support plates 6, and a plurality of through holes 7 are formed in the support plates 6. The through holes 7 are elliptical, and the plurality of through holes 7 on the same support plate 6 are arranged at equal intervals. The plurality of support mechanisms 5 are vertically or horizontally arranged, respectively. The two support plates 6 on the same support mechanism 5 are arranged in parallel and form a channel. The channel can be used to arrange and manage various cables and data lines. By concentrating the wires and pipelines in these channels, the layout can be kept neat and orderly, and the risk of cable crossing and interference can be reduced. In some cases, these channels can also be used as mounting brackets or rails to fix sensors or other small modules, ensuring that they are stably installed at the designated positions.
[0027] As shown in Figure 1 and Figure 4 , ventilation openings are formed on the left and right sides of the shell 1, and the two ventilation openings are symmetrically arranged. A dustproof air guide mechanism 8 is arranged in the ventilation opening. An external pipe 9 is arranged on the inner wall of the left and right sides of the shell 1. The external pipe 9 is inclined. The external pipe 9 is connected to the outside, and plays a role in ventilation and dust prevention.
[0028] It should be noted that the plurality of heat dissipation units 4 are horizontally placed to ensure that air enters from one side of the ventilation opening, passes through the heat dissipation mechanism 3, and is discharged from the other side of the ventilation opening, forming a more direct air convection channel and improving the heat dissipation efficiency. The horizontal arrangement allows the airflow to cover the surface of the heat dissipation unit 4 more evenly, avoiding local hot spots that may occur when the heat dissipation unit 4 is vertically placed. This ensures that the entire surface of the heat dissipation unit 4 can effectively participate in the heat dissipation process. The two ventilation openings are respectively arranged as an air inlet and an air outlet, which effectively prevents the hot air from flowing back to the air inlet, avoids the heated air from being sucked into the system again, and reduces the heat dissipation effect.

A plurality of connecting holes 15 are formed in the front side of the partition 2. The heat dissipation control valve 11 is used for manual or automatic power cut-off to ensure safety; the socket 12 provides a temporary power interface for maintenance tools or other equipment; the protector 13 includes overvoltage, overcurrent, short circuit and other protection devices to ensure automatic power-off in abnormal conditions and prevent damage to equipment or cause safety accidents; the valve 14 controls the opening and closing of the heat dissipation mechanism 3, adjusts the working state of the fan according to the information feedback by the temperature sensor, and ensures that the internal components are within the appropriate working temperature range.
[0032] The front side of the partition 2 is provided with a charging controller 16, a billing unit 17 and a communication module 18, and the mounting mechanism supports the charging controller 16, the billing unit 17 and the communication module 18. The charging controller 16 is the core of the management system, which is used to control the entire charging process, monitor the battery status, adjust the charging rate, and communicate with the vehicle to ensure safe charging; the billing unit 17 is provided with an electric energy meter, a microcontroller and a payment interface, etc., which is used to accurately record the consumed energy and calculate the fee, and provides a payment interface for users; the communication module 18 allows the charging pile to exchange data with external systems.
