[0002] Due to the rapid development of the electric vehicle industry, the performance and reliability of charging piles, as key equipment for electric vehicle energy replenishment, are receiving increasing attention. However, charging piles generate a lot of heat during operation. If heat dissipation is inadequate, it will not only affect the normal operation of the charging pile and shorten its service life, but also cause safety hazards.

[0003] A search revealed Chinese patent publication number CN212073729U, which relates to a heat dissipation device for car charging piles. The charging pile includes a main body with an outer shell. The outer surface of the outer shell has heat dissipation holes. The device includes a sealing member disposed on the inner surface of the outer shell, which closes or opens the heat dissipation holes. The sealing member includes a rotating shaft with a cover fixedly connected to its outer surface. The cover rotates with the shaft, and a soft pad is fixedly connected to the outer surface of the cover near the heat dissipation holes. A drive motor is fixedly connected inside the charging pile main body, and one end of the rotating shaft is fixedly connected to the drive end of the drive motor. This heat dissipation device for car charging piles has a simple structure, is easy to operate, and is flexible in use, effectively improving the heat dissipation capacity of the charging pile and facilitating its widespread use. However, in actual use, because the device dissipates heat naturally through the heat dissipation holes, the heat generated by the charging pile during operation dissipates faster than the natural heat dissipation through the holes, resulting in low heat dissipation efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a device to facilitate heat dissipation of car charging piles, aiming to improve the problem of low heat dissipation efficiency in the prior art, where the heat generated by the charging box during operation is faster than the heat dissipation through the heat dissipation holes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for facilitating heat dissipation of car charging piles, comprising a charging box, a protective door fixedly connected to the front side of the charging box, an exhaust fan fixedly connected to the top of the charging box, a power supply fixedly connected to the rear side of the interior of the charging box, two wires connected to the upper and lower sides of the power supply, two fans fixedly connected to the left and right sides of the interior of the charging box, multiple wires and fans electrically connected, multiple vents opened at the bottom of the left and right sides of the charging box, multiple heat dissipation fins fixedly connected to the rear side of the charging box, and a filter mechanism provided on the left and right sides of the interior of the charging box.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a device for facilitating heat dissipation of car charging piles, including a charging box 1. A protective door 3 is fixedly connected to the front side of the charging box 1. An exhaust fan 4 is fixedly connected to the top of the charging box 1. A power supply 5 is fixedly connected to the rear side of the inside of the charging box 1. Two wires 6 are connected to the upper and lower sides of the power supply 5. Two fans 7 are fixedly connected to the left and right sides of the inside of the charging box 1. The power from the power supply 5 is transmitted to the fans 7 through the wires 6. Multiple wires 6 and fans 7 are electrically connected. Multiple vents 8 are provided at the bottom of the left and right sides of the charging box 1. The exhaust fan 4, fans 7 and vents 8 form an airflow path from bottom to top, improving heat dissipation efficiency. Multiple heat dissipation fins 9 are fixedly connected to the rear side of the charging box 1 to increase the heat dissipation effect. Filter mechanisms 2 are provided on the left and right sides of the inside of the charging box 1 to filter dust entering through the vents 8.

[0040] Specifically, the front of the charging box 1 is equipped with a fixed protective door 3 to prevent accidental contact of internal components by external objects. An exhaust fan 4 is fixed on the top of the charging box 1, and a power supply 5 is fixed inside the rear of the charging box 1. Two wires 6 are connected to the top and bottom of the power supply 5. The wires 6 are electrically connected to four fans 7 on the left and right sides to supply power to the fans 7. When the fans 7 are turned on, they draw in external cold air through the vents 8 at the bottom. The vents 8 are distributed on the bottom left and right sides of the charging box 1. The exhaust fan 4, fans 7 and vents 8 work together to form an airflow path that enters from the bottom and exits from the top, accelerating air circulation and efficiently removing heat. Multiple heat dissipation fins 9 are also fixed on the rear of the charging box 1, which greatly increases the heat dissipation area and further improves the heat dissipation effect, ensuring that the charging box 1 can operate stably under various working conditions.

[0041] Reference Figure 5 The filtering mechanism 2 includes two filter screens 202.

Users can easily control the start, stop, and setting of the charging mode of the charging box 1 through the buttons 13. On the right side of the charging box 1, two hinges 14 connect it to the left side of the protective door 3, so that the protective door 3 can be opened and closed flexibly, providing convenience for the maintenance and operation of the internal components.

[0045] Reference Figure 1 and Figure 2 A support plate 15 is fixedly connected to the bottom of the control panel 12. The rear side of the support plate 15 is fixedly connected to the front side of the protective door 3 to support the control panel 12. Multiple support rods 16 are fixedly connected to the bottom of the support plate 15. The bottom of the multiple support rods 16 is fixedly connected to the bottom of the front side of the protective door 3 to increase the support of the support plate 15. Support columns 17 are fixedly connected to the four corners of the bottom of the charging box 1. Anti-slip sleeves 18 are fixedly connected to the bottom of the multiple support columns 17 to prevent movement.

[0046] Specifically, the bottom of the control panel 12 is provided with a support plate 15, which is fixed to the front of the protective door 3 to provide reliable support for the control panel 12. To enhance the support capacity of the support plate 15, multiple support rods 16 are connected to its bottom. The bottom of the multiple support rods 16 is also fixed to the bottom of the front of the protective door 3, ensuring the stability of the control panel 12 from multiple directions. Support columns 17 are installed at the four corners of the bottom of the charging box 1, and each support column 17 is equipped with an anti-slip sleeve 18 at its bottom, which can effectively prevent the charging box 1 from shifting during use.

[0047] Working principle: When the charging box 1 starts working, the power supply 5 starts to supply power to various components. The fan 7, as a key component for introducing cold air, starts after power is supplied. Since the fan 7 is installed on the left and right sides inside the charging box 1, the suction force generated can draw in external cold air from the vents 8 distributed at the bottom of the left and right sides of the charging box 1. The exhaust fan 4 at the top is also running, continuously exhausting air outward, creating a negative pressure environment inside the charging box 1. Under this negative pressure and the push of the fan 7, an airflow path is formed with air entering from the bottom vents 8 and exiting from the top exhaust fan 4. Hot air is continuously carried out of the charging box 1 with this airflow. Multiple heat dissipation fins 9 fixed on the rear side of the charging box 1 increase the heat dissipation area and accelerate the dissipation of heat to the surrounding environment. Under the dual action of air circulation heat dissipation and heat dissipation fins 9, the heat generated by the operation of the charging box 1 can be dissipated in a timely and effective manner, ensuring its stable operation under various working conditions.

[0048] Furthermore, the slot 1 201 located at the bottom left and right sides of the charging box 1 provides initial positioning for the installation of the filter 202. During installation, the card plate 204 is inserted along the slot 1 201. Utilizing its sliding engagement with the slot 1 201, the card plate 204 can be easily guided to the appropriate position. Simultaneously, it is embedded in the slot 2 203 on the right side of the filter 202, initially fixing the filter 202 to the bottom left and right sides inside the charging box 1. A slot 205 and a matching card block 206 are designed on the top of the card plate 204. The sliding engagement of the card block 206 with the slot 205 allows the card block 206 to slide precisely into the slot 205. After the card block 206 slides in, the locking structure formed by it and the slot 205 effectively prevents the card plate 204 from shifting in the horizontal and vertical directions, thus firmly stabilizing the filter 202 at the bottom of the charging box 1. All air entering the charging box 1 must pass through the filter 202, ensuring the cleanliness of the internal components.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
