[0002] The widespread adoption of electric vehicles is inseparable from the support of charging infrastructure. The construction of electric vehicle charging stations is also constantly advancing. As a green mode of transportation, electric vehicles are being used more and more widely in daily life due to increased environmental awareness and adjustments in the energy structure, and the deployment of charging stations is also becoming more and more extensive.

[0004] However, existing charging stations are not convenient for internal air circulation and heat dissipation according to usage needs, which affects heat dissipation efficiency and usage effect;

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes an electric vehicle charging pile with high-efficiency heat dissipation. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electric vehicle charging station with high-efficiency heat dissipation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat dissipation electric vehicle charging pile, comprising a charging pile body, charging modules mounted on the front and rear sides of the charging pile body, and a power supply and control module integrated inside the charging pile body, a heat dissipation coil mounted inside the charging pile body, an exhaust fan mounted on the upper end of the heat dissipation coil, two sets of exhaust fans mounted on the top sides of the charging pile body, a transition fan mounted on the lower end of the heat dissipation coil, and an air inlet pipe connected to the lower end of the transition fan, an overcooling coil sleeved outside the air inlet pipe, and water inlet and outlet pipes integrally provided at both ends of the overcooling coil.

[0008] As a further step of this solution, the bottom of the main body of the electric pile is supported by a support frame, and the bottom of the support frame is supported by a support base, and the bottom of the support base is supported by a base plate. The inlet and outlet water pipes are inserted and installed inside the support base, and the support base has through holes corresponding to the inlet and outlet water pipes. The upper part of the inlet and outlet water pipes is fitted with a cap ring, and the cap ring is installed on the top surface of the support base. The side of the base plate has inlet and outlet grooves corresponding to the inlet and outlet water pipes.

[0009] As a further step of this solution, the support base is equipped with a distribution box on both the front and rear sides. The distribution box is hinged to the front side with a cabinet door. The bottom of the distribution box and the support base are provided with corresponding bottom grooves. The base plate is provided with side groove holes on both the front and rear sides. The base plate is provided with side screw grooves at the corners around the perimeter. The upper end of the side screw groove is integrally provided with a side recessed groove.

[0010] As a further step of this solution, an inner partition is integrally provided inside the main body of the charging pile. The two sets of heat dissipation coils are located between the inner wall of the charging pile main body and the inner partition. Ventilation slots are opened inside the inner partition. Outer baffles are installed on the hinges on both sides of the charging pile main body. The heat dissipation coils are arranged in an S-shape with up-and-down undulating connection. An air outlet corresponding to the exhaust fan is integrally provided at the upper end of the heat dissipation coils. An air inlet that connects to the transition fan is integrally provided at the lower end of the two sets of heat dissipation coils.

[0011] As a further step of this solution, an upper cover is installed above the exhaust fan and the heat dissipation coil, and the upper end of the upper cover is set in an arc shape. A rainproof eaves is integrally provided on the side of the upper cover.

[0012] As a further improvement of this solution, a three-way pipe is integrally provided at the upper center of the air inlet pipe, and the upper end of the three-way pipe is threadedly assembled with the transition fan.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this utility model, the arrangement of the heat dissipation coil, in conjunction with the exhaust fan and the transition fan, facilitates the guidance and delivery of air into the interior of the charging pile body. Simultaneously, the S-shaped arrangement, along with the air outlet and inlet, facilitates the upward circulation and heat conduction of air, allowing the hot air inside the charging pile body to be carried away quickly. Furthermore, the upper cover and rainproof eaves facilitate the covering and protection of the upper part. The inner partition and ventilation slots facilitate the isolation of the interior of the charging pile body, allowing for efficient heat dissipation through the heat dissipation coil, making it more convenient to use. The arrangement of two sets of S-shaped heat dissipation coils further enhances the convenience of heat dissipation for the charging pile body.

[0016] In this invention, the cooling coil is coiled and wound around the inlet and outlet water pipes and connectors. After the water is connected to the tap water or other water source, the water flows from one side to the other, relatively cooling the inside of the air inlet pipe. This results in a relatively low air temperature when the air inlet pipe and air inlet fan supply air to the transition fan and cooling coil, making the circulating cooling more efficient. During circulation, the air inlet pipe and transition fan supply lower temperature air to the cooling coil, which is then transported through the S-shaped cooling coil pipes more conveniently, facilitating efficient cooling and making operation more convenient. Furthermore, the base plate, support seat, and support frame facilitate the assembly of the inlet and outlet water pipes and connectors, as well as the connection and assembly of the power distribution box, charging module, and internal power control module. At the same time, the connection of the connectors, inlet and outlet water pipes, and cooling coils does not hinder the flow and use of tap water, reducing related costs and making efficient cooling operation more convenient.
