Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to a new energy vehicle charging pile with a high-efficiency heat dissipation structure. Background Technology

[0002] New energy charging piles can be fixed to the ground or walls and installed in public buildings, shopping malls, public parking lots, and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels.

[0003] Chinese patent CN114084016A discloses a charging pile for new energy vehicles with a heat dissipation-facilitated and protective structure. The charging pile includes a main control mechanism, a stabilizing mechanism around its bottom, a protective mechanism on its outer walls, and a heat dissipation mechanism inside. This charging pile, with its heat dissipation-facilitated and protective structure, uses a base that matches the dimensions of the pile's bottom, along with the stabilizing mechanism, to fix the overall position of the charging pile and ensure a more secure connection. When the charging pile is subjected to external impact during use, the protective mechanism disperses the force, reducing localized impact stress and providing a certain degree of protection. The heat dissipation mechanism then provides efficient bidirectional heat dissipation, addressing the safety hazards caused by internal heat buildup during long-term charging.

[0004] The shortcomings of the above-mentioned existing technical solutions are as follows: a stabilizing mechanism is set at the bottom and buried underground, but the heat source is dissipated only through the cooling fan of the heat dissipation mechanism. However, the underground temperature is much lower than the surface temperature in summer. The above-mentioned device does not combine the stabilizing mechanism with the heat dissipation mechanism, and cannot use the temperature difference between the underground and the surface to dissipate heat from the heat source, resulting in poor heat dissipation effect and low heat dissipation efficiency. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a new energy vehicle charging pile with a high-efficiency heat dissipation structure, thereby resolving the problems existing in the prior art.

[0006] According to a first aspect of this utility model, a new energy vehicle charging pile with a high-efficiency heat dissipation structure is provided, comprising:

[0007] A heat-conducting base has heat-conducting pipes evenly distributed and fixedly connected on the upper surface of the heat-conducting base, and heat-conducting plates fixedly connected on the heat-conducting pipes. Heat dissipation pipe 1 is evenly distributed and fixedly connected on the lower surface of the heat-conducting base, and heat dissipation pipe 2 is evenly distributed along the length of several heat dissipation pipe 1. The surfaces of heat dissipation pipe 1 and heat dissipation pipe 2 are coated with a layer of anti-corrosion coating.

[0008] A fixed base is fitted and fixedly connected to the outside of the heat-conducting base. Embedded steel bars are evenly distributed and fixedly connected to the side end face of the fixed base. A protective enclosure is fixedly connected to the lower end of the fixed base. The protective enclosure is set at the side end of heat dissipation pipe one and heat dissipation pipe two.

[0009] As a further embodiment of this invention: the anti-corrosion coating is a graphene-based anti-corrosion coating.

[0010] As a further embodiment of this utility model: the heat conduction pipe is arranged in a U-shape, the heat dissipation pipe one is arranged in an inverted U-shape, the heat dissipation pipe two is an annular heat dissipation pipe, the annular heat dissipation pipe two is sleeved and fixedly connected to the outside of several heat dissipation pipes one, and the heat dissipation pipe one and heat dissipation pipe two together form a cage-like structure.

[0011] As a further embodiment of this utility model: a heat dissipation plate is evenly distributed and fixedly connected inside the cage-like structure formed by heat dissipation pipe one and heat dissipation pipe two, and a through groove is opened through one end of the heat dissipation plate near the heat conduction base.

[0012] As a further embodiment of this utility model: a first fixed side plate and a second fixed side plate are fixedly connected to the upper end face of the fixed base respectively. The first fixed side plate and the second fixed side plate are symmetrically arranged on the fixed base. A first cooling fan is fixedly connected to the first fixed side plate and a second cooling fan is fixedly connected to the second fixed side plate.

[0013] As a further embodiment of this utility model: Cooling fan one is an intake fan, and cooling fan two is an exhaust fan.

[0014] As a further embodiment of this utility model: four protective enclosures are provided, and the four protective enclosures are fixedly connected to the four sides of the heat dissipation pipe one and the heat dissipation pipe two.

[0015] As a further embodiment of this utility model: a protective shell is fixedly connected to the upper end of the fixed base, and the charging module, heat pipe, heat plate and heat base are all disposed inside the protective shell, and cooling fan one and cooling fan two are both embedded in the protective shell.

[0016] The beneficial effects of this utility model are:

[0017] When heat dissipation is required, this utility model uses cooling fan one as an intake fan and cooling fan two as an exhaust fan. Cooling fan one and cooling fan two form a heat dissipation air duct to dissipate heat from the charging module. At the same time, the heat-conducting plate contacts the heat source and transfers heat through the heat-conducting pipe and the heat-conducting base to the heat dissipation pipe one and heat dissipation pipe two pre-buried in the soil for heat dissipation. The length of heat dissipation pipe one is 1.5 meters. In summer, the temperature 1.5 meters underground can be more than 20 degrees Celsius lower than the surface temperature. Moreover, the transfer of surface temperature is delayed, and it takes 2-4 hours for surface heat to be transferred underground. During the hottest period of the day at noon in summer, the heat source heat is introduced into the ground through the heat-conducting plate, heat-conducting pipe and heat-conducting base and then dissipated through heat dissipation pipe one and heat dissipation pipe two, which can effectively improve the heat dissipation efficiency of the charging pile during charging.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Reference Figures 1 to 5 This utility model provides a new energy vehicle charging pile with a high-efficiency heat dissipation structure, including a heat-conducting base 5 and a fixed base 10. Heat-conducting pipes 3 are evenly distributed and fixedly connected to the upper surface of the heat-conducting base 5, and heat-conducting plates 4 are fixedly connected to the heat-conducting pipes 3. Heat dissipation pipes 6 are evenly distributed and fixedly connected to the lower surface of the heat-conducting base 5, and heat dissipation pipes 7 are evenly distributed along the length of the heat dissipation pipes 6. The surfaces of both heat dissipation pipes 6 and 7 are coated with an anti-corrosion coating, which is a graphene-based anti-corrosion coating. In use, the heat dissipation pipes 6 and 7 are pre-buried in the soil. The heat-conducting plate 4 contacts the heat source, transferring heat through the heat-conducting pipes 3 and the heat-conducting base 5 to the pre-buried heat dissipation pipes 6 and 7. Heat dissipation is achieved through heat pipe 6, which is 1.5 meters long. In summer, the temperature 1.5 meters underground can be more than 20 degrees Celsius lower than the surface temperature. Moreover, the transfer of surface temperature is delayed, and it takes 2-4 hours for surface heat to be transferred underground. During the hottest period of daytime in summer, the heat source heat is introduced underground through heat-conducting plate 4, heat-conducting pipe 3, and heat-conducting base 5, and then dissipated through heat pipe 6 and heat pipe 7. This can effectively improve the heat dissipation efficiency of the charging pile during charging. Fixed base 10 is sleeved and fixedly connected to the outside of heat-conducting base 5. Pre-embedded steel bars 12 are provided on the side end face of fixed base 10. A protective enclosure 11 is fixedly connected to the lower end of fixed base 10. The protective enclosure 11 is set on the side end of heat pipe 6 and heat pipe 7.

[0029] Graphene-based anti-corrosion coatings offer both high thermal conductivity and excellent corrosion protection. The two-dimensional sheet structure of graphene can form conductive and thermally conductive channels within the coating, while also creating a labyrinthine physical barrier to isolate corrosive media. Its single-atom layer thickness (approximately 0.335 nm) can significantly reduce the coating's thermal resistance, avoiding negative impacts on the heat dissipation performance of the metal substrate. Graphene's surface is highly hydrophobic (contact angle >150°), reducing moisture retention and the risk of electrochemical corrosion. It also prevents the reduction in heat dissipation efficiency caused by dirt accumulation, making it suitable for high humidity and salt spray environments.

[0030] Heat dissipation pipe 6 and heat dissipation pipe 7 together form a cage-like structure. Heat dissipation plate 8 is evenly distributed and fixedly connected inside the cage-like structure formed by heat dissipation pipe 6 and heat dissipation pipe 7. A through groove 9 is opened through one end of heat dissipation plate 8 near the heat conduction base 5. The end of heat dissipation plate 8 near the heat conduction base 5 is closer to the ground surface. The soil temperature near the ground surface is relatively higher than that of the soil layer far from the ground surface. By opening through groove 9, the application of metal materials can be saved. At the same time, the overall stability of heat dissipation pipe 6, heat dissipation pipe 7 and heat dissipation plate 8 for fixing the charging pile can be increased. The surface of heat dissipation plate 8 is coated with a graphene-based anti-corrosion coating.

[0031] Fixed side plate 13 and fixed side plate 2 14 are fixedly connected to the upper end face of the fixed base 10. Fixed side plate 13 and fixed side plate 2 14 are symmetrically arranged on the fixed base 10. Cooling fan 15 is fixedly connected to fixed side plate 13 and cooling fan 2 16 is fixedly connected to fixed side plate 2 14. Cooling fan 15 is an intake fan and cooling fan 2 16 is an exhaust fan.

[0032] The heat conduction pipe 3 is U-shaped, the heat dissipation pipe 6 is inverted U-shaped, the heat dissipation pipe 7 is a ring-shaped heat dissipation pipe, the ring-shaped heat dissipation pipe 7 is sleeved and fixedly connected to the outside of several heat dissipation pipes 6, four protective enclosures 11 are provided, the four protective enclosures 11 are fixedly connected to the four sides of the heat dissipation pipes 6 and 7, and several pre-embedded steel bars 12 are evenly distributed and fixedly connected to the side of the fixed base 10.

[0033] The heat pipe 3 is U-shaped and has heat-conducting plates 4 fixedly connected to both sides. A charging module 2 is set between the two heat-conducting plates 4. The charging module 2 is the main heat source in the charging pile. The heat-conducting plates 4 contact the charging module 2 and transfer the heat through the heat-conducting pipe 3 and the heat-conducting base 5 to the heat dissipation pipe 6 and heat dissipation pipe 7 pre-buried in the soil for heat dissipation. A protective shell 1 is fixedly connected to the upper end of the fixed base 10. The charging module 2, heat-conducting pipe 3, heat-conducting plates 4 and heat-conducting base 5 are all set inside the protective shell 1. Cooling fan 15 and cooling fan 26 are both embedded in the protective shell 1.

[0034] Workflow:

[0035] First, the heat dissipation structure needs to be fixedly installed in conjunction with the charging pile. A pit is dug according to the dimensions of the cage-like structure formed by heat dissipation pipe 6 and heat dissipation pipe 7. The heat dissipation mechanism, consisting of charging module 2, heat-conducting pipe 3, heat-conducting plate 4, heat-conducting base 5, heat dissipation pipe 6, heat dissipation pipe 7, and heat dissipation plate 8, is placed in the pit. Heat dissipation pipe 6, heat dissipation pipe 7, and heat dissipation plate 8 are then buried with sand. The fixing base 10 and protective enclosure 11 are then fitted onto the outside of the heat dissipation mechanism, and the protective enclosure 11 is inserted into the soil, so that the fixing base 10 fits onto the outside of the heat-conducting base 5, and the heat-conducting base 5 and fixing base 10 are tightly welded together. Then, the protective outer shell 1 is installed, and the overall wiring of the charging pile is completed. After completing the above steps, the pre-installation of a single charging pile can be achieved. After all charging piles are pre-installed, the pre-embedded steel bars 12 are embedded in the poured concrete layer to ensure the charging pile... Further fixing allows for the overall fixed installation of the charging pile. When heat dissipation is required, cooling fan 15 acts as the intake fan, and cooling fan 16 acts as the exhaust fan. Cooling fan 15 and cooling fan 16 form a heat dissipation air duct to dissipate heat from the charging module 2. At the same time, the heat-conducting plate 4 contacts the heat source and transfers heat through the heat-conducting pipe 3 and the heat-conducting base 5 to the heat dissipation pipe 16 and heat dissipation pipe 27 buried in the soil. The length of heat dissipation pipe 16 is 1.5 meters. In summer, the temperature 1.5 meters underground can be more than 20 degrees Celsius lower than the surface temperature. Moreover, the transfer of surface temperature is delayed, and it takes 2-4 hours for surface heat to transfer underground. During the hottest period of daytime in summer, the heat source heat is introduced underground through the heat-conducting plate 4, heat-conducting pipe 3, and heat-conducting base 5 and dissipated through heat dissipation pipe 16 and heat dissipation pipe 27, which can effectively improve the heat dissipation efficiency of the charging pile during charging.
