Description

A liquid-cooled fast charging station Technical Field

[0001] The embodiments of the present invention relate to the field of charging pile technology, specifically to a liquid-cooled fast charging pile. Background Technology

[0002] With the rapid development of the new energy vehicle industry, fast charging technology has become a key core technology for improving the user charging experience and promoting the popularization of new energy vehicles. Liquid-cooled fast charging piles, with their advantages of high heat dissipation efficiency and good heat dissipation uniformity, can effectively solve the problem of a large amount of heat generated by the charging module and charging cable during high-power charging. Compared with traditional air-cooled charging piles, they can better meet the needs of high-power, long-term fast charging, and are therefore widely used in public charging stations, highway service areas and other scenarios.

[0003] Currently, most liquid-cooled fast charging piles use fixed-layout heat exchange components in their cooling systems. These components are connected to cooling pipes within the pile body, and the cooling medium is cooled through refrigeration units or natural heat dissipation, thereby cooling the charging module and charging cables. However, existing cooling systems still have many technical shortcomings in practical applications, making it difficult to balance heat dissipation efficiency, energy consumption control, and environmental adaptability. Summary of the Invention

[0004] To overcome the above-mentioned defects, embodiments of the present invention provide a liquid-cooled fast charging pile, which solves the technical problems of insufficient heat dissipation efficiency and high energy consumption in the cooling structure of charging piles in related technologies.

[0005] According to one aspect, at least one embodiment of the present invention provides a liquid-cooled fast charging station, comprising:

[0006] The pile body has a charging cable, and a charging gun is connected to the charging cable;

[0007] A cold air chamber is installed inside the pile body to provide a low-temperature environment;

[0008] A cooling device is provided for connection to the cooling pipeline within the pile body. The cooling device includes a heat exchange component one and a heat exchange component two, both of which are connected to the cooling pipeline via pipes.

[0009] The first heat exchange component is disposed within the cold air cavity, and the second heat exchange component is movable. The second heat exchange component has an internal state and an external state. When the second heat exchange component is in the internal state, it is located within the cold air cavity and exchanges heat with the first heat exchange component. When the second heat exchange component is in the external state, it is located outside the pile body and exchanges heat with the external environment.

[0010] For example, at least one embodiment of this disclosure provides a liquid-cooled fast charging station.

[0011] Both the top of the pile body and the cold air cavity are provided with openings;

[0012] The second heat exchange component is vertically mounted and can move up and down to enter the cold air cavity through an opening or be located on the top of the pile body.

[0013] For example, at least one embodiment of this disclosure provides a liquid-cooled fast charging station, which further includes:

[0014] A lifting assembly is disposed within the cooling air chamber;

[0015] An adjustment seat is provided at the lifting end of the lifting assembly, and the second heat exchange assembly is provided on the adjustment seat. The adjustment seat is used to adjust the horizontal rotation angle and the vertical swing angle of the second heat exchange assembly.

[0016] For example, at least one embodiment of this disclosure provides a liquid-cooled fast charging station, which further includes:

[0017] A heat insulation plate is disposed on one side of the second heat exchange component. The heat insulation plate can rotate with the second heat exchange component and be located on the near light side or the far light side. When the heat insulation plate is located on the near light side, the heat insulation plate is used to shield the second heat exchange component from light and heat. When the heat insulation plate is located on the far light side, the heat insulation plate is used to reflect light onto the second heat exchange component.

[0018] For example, at least one embodiment of this disclosure provides a liquid-cooled fast charging station.

[0019] The side of the heat insulation plate closest to the second heat exchange component has a reflective layer, and the side of the heat insulation plate furthest from the second heat exchange component has a heat insulation layer.

[0020] For example, at least one embodiment of this disclosure provides a liquid-cooled fast charging station.

[0021] The side of the heat insulation plate closest to the second heat exchange component is concave to concentrate and reflect light onto the second heat exchange component.

[0022] For example, at least one embodiment of this disclosure provides a liquid-cooled fast charging station.

[0023] The outer surface of the heat exchange component has a heat-absorbing coating.

[0024] For example, at least one embodiment of this disclosure provides a liquid-cooled fast charging pile, wherein the adjustment base includes:

[0025] A base is disposed at the lifting end of the lifting assembly;

[0026] A rotating block is horizontally rotatably mounted on the top surface of the base;

[0027] A limiting member is disposed on the rotating block, and the limiting member is used to limit the position of the rotating block;

[0028] The swing block is vertically swinging on the rotating block, and the second heat exchange component is disposed on the swing block.

[0029] For example, at least one embodiment of this disclosure provides a liquid-cooled fast charging station.

[0030] Both heat exchange component one and heat exchange component two are heat exchange tubes or heat exchange plates.

[0031] For example, at least one embodiment of this disclosure provides a liquid-cooled fast charging station, which further includes:

[0032] A rain cover is installed on the top surface of the pile body and can be lowered to cover the top surface of the pile body.

[0033] The beneficial effects of the embodiments of the present invention are as follows:

[0034] In this invention, the charging pile body, charging cable, and charging gun constitute the basic charging structure of the charging pile, realizing the transmission and supply of electrical energy and providing charging function for the device to be charged. The cold air cavity provides a stable low-temperature heat exchange environment for the heat exchange component one. The cooling device achieves the cooling medium temperature reduction through the cooperation of heat exchange component one and heat exchange component two, thereby dissipating heat for the charging module and charging cable inside the pile body. The three work together to solve the technical problem of untimely heat dissipation in liquid-cooled fast charging piles during high-power charging.

[0035] Heat exchange component one is fixedly installed inside the cooling chamber. Under the action of the refrigeration unit, it continuously cools the cooling medium, ensuring the basic heat dissipation capacity of the cooling system and guaranteeing stable operation of the charging pile under normal conditions. Heat exchange component two is movable, switching between internal and external states according to actual heat dissipation needs. When the charging pile is in high-power charging mode and generates a lot of heat, heat exchange component two switches to the internal state, exchanging heat with heat exchange component one to increase the heat dissipation area, improve heat dissipation efficiency, and prevent the cooling medium temperature from becoming too high, which would reduce the heat dissipation effect. When the external ambient temperature is low (which can be controlled by a valve to use only heat exchange component two), heat exchange component two switches to the external state, directly exchanging heat with the external environment without activating the refrigeration unit, reducing the energy consumption of the charging pile and achieving energy-saving operation.

[0036] Both heat exchange components one and two in the cooling device are connected to the cooling pipeline. Valves control the flow path of the cooling medium, allowing the two heat exchange components to work independently or in conjunction, thus improving the flexibility and adaptability of the cooling system and enabling it to cope with different working conditions and environmental conditions. The isolation structure between the cold air chamber and other areas within the pile body prevents the low-temperature environment from affecting other electrical components within the pile body, ensuring the operational stability of the electrical components, while also reducing the loss of cold air and improving the working efficiency of the refrigeration unit.

[0037] The heat dissipation fins on heat exchange component one increase the contact area with the air inside the cooling chamber, enhancing the heat exchange effect and enabling the cooling medium to cool down rapidly. The moving mechanism drives heat exchange component two to switch positions, ensuring that heat exchange component two can maintain reliable communication with the cooling pipeline in both internal and external states, guaranteeing the sealing and flow of the cooling circuit, and preventing cooling medium leakage.

They are used only for the convenience of description and simplification of operation, and are not intended to 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 the present invention.

[0051] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0052] As shown in Figures 1-6, a liquid-cooled fast-charging pile according to an embodiment of the present invention is illustrated. The pile body 1 has an internal installation chamber. A cable outlet is provided on one side wall of the pile body 1. One end of the charging cable 11 passes through the cable outlet and is electrically connected to the charging module inside the pile body 1. The other end of the charging cable 11 is fixedly connected to a charging gun 12, which is used to interface with the charging interface of the device to be charged to achieve power transmission. A cooling air chamber 2 is fixedly installed inside the pile body 1. The cooling air chamber 2 forms a space for accommodating a heat exchange component 31. An isolation structure is provided between the cooling air chamber 2 and the internal installation chamber of the pile body 1 to avoid unnecessary heat exchange between the low-temperature environment inside the cooling air chamber 2 and other areas inside the pile body 1.

[0053] Cooling pipes are laid inside the pile body 1. These cooling pipes are connected to the internal pipes of the charging module and the wiring harness sheath of the charging cable 11. They are used to absorb the heat generated when the charging module is working and the heat generated when the charging cable 11 transmits electrical energy. The inlet and outlet of the cooling pipes are connected to the inlet and outlet of the cooling device 3, respectively, forming a closed cooling loop. The cooling loop is filled with a cooling medium. The cooling device 3 includes a heat exchange component 1 31, a heat exchange component 2 32, and connecting pipes. The inlet and outlet of the heat exchange component 1 31 are connected to the inlet and outlet of the cooling pipes, respectively, through connecting pipes. The inlet and outlet of the heat exchange component 2 32 are connected to the inlet and outlet of the cooling pipes, respectively, through connecting pipes. Valves are installed on the connecting pipes to control the on / off state, allowing the use of either heat exchange component 1 31 or heat exchange component 2 32.

[0054] The heat exchange component 31 is fixedly installed inside the cold air cavity 2. Several heat dissipation fins are provided on the heat exchange component 31 to increase the contact area between the heat exchange component 31 and the air inside the cold air cavity 2. A refrigeration unit is installed inside the cold air cavity 2 to reduce the air temperature inside the cold air cavity 2, providing a stable low-temperature heat exchange environment for the heat exchange component 31.

[0055] The heat exchange component 2 32 is connected to the pile body 1 through a moving mechanism. The moving mechanism drives the heat exchange component 2 32 to switch positions between inside and outside the pile body 1, so that the heat exchange component 2 32 has an internal state and an external state.

[0056] When heat exchange component 2 32 is in the internal state, the driving component drives heat exchange component 2 32 to slide along the guide rail into the cold air cavity 2. At this time, the reversing valve switches to the passage that allows the cooling medium to flow through heat exchange component 1 31 and heat exchange component 2 32 at the same time. Heat exchange component 1 31 and heat exchange component 2 32 exchange heat with the cooling medium together in the low temperature environment inside the cold air cavity 2, dissipating the heat in the cooling medium into the cold air cavity 2. Then, the refrigeration unit discharges the heat from the cold air cavity 2, thereby achieving the cooling of the cooling medium.

[0057] When heat exchange component 2 32 is in the external state, the driving component drives heat exchange component 2 32 to slide along the guide rail, extending through the channel opened on the side wall of pile body 1 to the outside of pile body 1. At this time, the valve is switched to allow the cooling medium to flow through the passage of heat exchange component 2 32. Heat exchange component 2 32 is in direct contact with the external environment and exchanges heat with the air in the external environment to dissipate the heat in the cooling medium to the external environment, thereby achieving the cooling of the cooling medium.

[0058] In this embodiment, the charging pile 1, charging cable 11, and charging gun 12 constitute the basic charging structure of the charging pile, realizing the transmission and supply of electrical energy and providing charging function for the device to be charged. The cold air cavity 2 provides a stable low-temperature heat exchange environment for the heat exchange component 31. The cooling device 3 achieves the cooling of the cooling medium through the cooperation of the heat exchange component 31 and the heat exchange component 32, thereby dissipating heat for the charging module and charging cable 11 in the charging pile 1. The three work together to solve the technical problem of untimely heat dissipation in the high-power charging process of the liquid-cooled fast charging pile.

[0059] Heat exchange component 1 (31) is fixedly installed inside the cooling chamber 2. Under the action of the refrigeration unit, it continuously cools the cooling medium, ensuring the basic heat dissipation capacity of the cooling system and guaranteeing stable operation of the charging pile under normal conditions. Heat exchange component 2 (32) is movable, switching between internal and external states according to actual heat dissipation needs. When the charging pile is in high-power charging mode and generates a large amount of heat, heat exchange component 2 (32) switches to the internal state, exchanging heat with heat exchange component 1 (31) to increase the heat dissipation area, improve heat dissipation efficiency, and prevent the cooling medium temperature from becoming too high, which would reduce the heat dissipation effect. When the external ambient temperature is low (this can be controlled by a valve to use only heat exchange component 2 (32)), heat exchange component 2 (32) switches to the external state, directly exchanging heat with the external environment without activating the refrigeration unit, reducing the energy consumption of the charging pile and achieving energy-saving operation.

[0060] In the cooling device 3, both heat exchange components 31 and 32 are connected to the cooling pipeline. Valves control the flow path of the cooling medium, allowing the two heat exchange components to work independently or in tandem. This enhances the flexibility and adaptability of the cooling system, enabling it to cope with different working conditions and environmental conditions. The isolation structure between the cold air chamber 2 and other areas within the pile body 1 prevents the low-temperature environment from affecting other electrical components within the pile body 1, ensuring the operational stability of the electrical components. Simultaneously, it reduces the loss of cold air and improves the working efficiency of the refrigeration unit.

[0061] The heat dissipation fins on heat exchange component 31 increase the contact area with the air inside the cold air chamber 2, enhancing the heat exchange effect and enabling the cooling medium to cool down rapidly. The moving mechanism drives heat exchange component 32 to switch positions, ensuring that heat exchange component 32 can maintain reliable communication with the cooling pipeline in both internal and external states, guaranteeing the sealing and flow of the cooling circuit, and preventing cooling medium leakage.

[0062] Furthermore, referring to Figure 1, a first opening is opened on the top surface of the pile body 1, and a second opening is opened on the top surface of the cold air chamber 2. The first opening and the second opening are arranged coaxially, and the diameter of the first opening is larger than the diameter of the second opening.

[0063] The outer diameter of heat exchange component 2 32 is smaller than the aperture of the second opening, ensuring that heat exchange component 2 32 can smoothly pass through the second opening and enter the cold air cavity 2. When heat exchange component 2 32 is in the internal state, heat exchange component 2 32 descends through the first opening and the second opening, extending into the cold air cavity 2 until heat exchange component 2 32 is completely located in the cold air cavity 2. At this time, heat exchange component 2 32 and heat exchange component 1 31 are arranged at intervals along the height direction of the cold air cavity 2. When heat exchange component 2 32 is in the external state, heat exchange component 2 32 rises and passes through the second opening and the first opening in sequence, rising to the top outside the pile body 1, so that heat exchange component 2 32 is completely separated from the pile body 1 and the cold air cavity 2.

[0064] In this embodiment, the coaxial openings at the top of the pile body 1 and the cooling air chamber 2 provide a reasonable channel layout for the lifting and lowering movement of the heat exchange component 32, avoiding the structural strength reduction and sealing problems caused by opening large-sized channels on the side wall of the pile body 1. Compared with a horizontally moving structure, the lifting-type heat exchange component 32 can make full use of the space at the top of the pile body 1, reducing the occupation of the internal installation space of the pile body 1. At the same time, when the heat exchange component 32 is in the external state, it is located at the top of the pile body 1, which allows for more full contact with the external air and improves the heat exchange efficiency.

[0065] Further, referring to Figure 3, the lifting assembly 4 is fixedly installed inside the air conditioning chamber 2. The lifting assembly 4 (not shown in the figure) includes a lead screw, a lead screw nut, and a drive motor. The drive motor is connected to the lead screw in a transmission manner. The lead screw nut is sleeved on the lead screw and is fixedly connected to the adjusting seat 5. The lead screw is arranged axially in the vertical direction. The drive motor drives the lead screw to rotate, thereby driving the lead screw nut and the adjusting seat 5 to rise and fall in the vertical direction.

[0066] The adjusting seat 5 is installed on the lifting end of the lifting assembly 4, that is, the bottom surface of the screw nut. The adjusting seat 5 includes a horizontal rotation mechanism and a vertical swing mechanism. The horizontal rotation mechanism is used to drive the heat exchange assembly 32 to rotate around the vertical axis, and the vertical swing mechanism is used to drive the heat exchange assembly 32 to swing around the horizontal axis.

[0067] During operation, the lifting component 4 drives the adjusting seat 5 and the heat exchange component 2 32 to rise and fall, thus switching states. When the heat exchange component 2 32 is in the external state, the horizontal rotation mechanism drives the rotating seat to rotate, causing the heat exchange component 2 32 to rotate horizontally and adjust its orientation on the horizontal plane. The vertical swing mechanism drives the swing frame to swing around the hinge axis, adjusting the tilt angle of the heat exchange component 2 32 so that the heat exchange component 2 32 can be aligned with the direction of air flow or the direction of sunlight.

[0068] In this embodiment, the horizontal rotation and vertical swing functions of the adjusting seat 5 allow the heat exchange component 32 to flexibly adjust its orientation and tilt angle in external conditions, solving the problem of environmentally limited heat exchange efficiency caused by the fixed setting of existing heat exchange components. When there is a directional airflow, the orientation of the heat exchange component 32 can be adjusted by horizontal rotation and vertical swing to align the heat dissipation fins with the airflow direction, accelerating airflow and improving heat dissipation efficiency. When solar-assisted heat exchange is required, the angle can be adjusted to align the heat exchange component 32 with the sunlight, improving the heat absorption effect. The structural design of the adjusting seat 5 makes the angle adjustment of the heat exchange component 32 more precise and its fixation more reliable, further improving the adaptability and operational stability of the cooling system.

[0069] Furthermore, referring to Figure 4, the heat insulation plate 6 has a flat plate structure and is fixedly installed on the side wall of the heat exchange component 32.

[0070] In this embodiment, the heat insulation plate 6 is mounted on the second heat exchange component and can rotate synchronously with the second heat exchange component 32, ensuring that the heat insulation plate 6 can always adjust its position according to the direction of light. This eliminates the need for an additional independent drive mechanism, simplifying the structural layout. The light-shielding and heat-insulating function on the near-beam side prevents direct sunlight from hitting the second heat exchange component 32, thus preventing excessive surface temperature and overload of the cooling medium, ensuring the stability of heat exchange. The reflective function on the far-beam side reflects the heat of the light to the second heat exchange component 32 when the ambient temperature is low, helping to increase the temperature of the cooling medium and preventing the low temperature of the cooling medium from affecting the operational stability of the charging pile's electrical components.

[0071] Furthermore, referring to Figure 4, the heat insulation plate 6 has a layered structure. A reflective layer 61 is fixedly installed on the side of the heat insulation plate 6 close to the heat exchange component 32. The reflective layer 61 completely covers the surface of this side. The connection surface between the reflective layer 61 and the heat insulation plate 6 is flat to ensure that the reflective layer 61 can be laid flat. A heat insulation layer 62 is fixedly installed on the side of the heat insulation plate 6 away from the heat exchange component 32. The heat insulation layer 62 also completely covers the surface of this side.

[0072] In this embodiment, the reflective layer 61 ensures that the heat insulation plate 6 can efficiently reflect light when it is on the far side, and concentrate the heat of the light to transfer to the heat exchange component 2 32, thereby improving the utilization rate of solar energy; the heat insulation layer 62 ensures that the heat insulation plate 6 can effectively block the transfer of external heat when it is on the near side, and prevent the heat exchange component 2 32 from being affected by the high temperature of the outside.

[0073] The two-layer structure arrangement allows the same structure of the insulation panel 6 to achieve two opposite functions, eliminating the need for separate light-shielding and reflector panels, simplifying the structure and reducing the space occupied.

[0074] Furthermore, the side of the heat insulation plate 6 closest to the heat exchange component 32 is designed as a concave surface, with the axis of the concave surface coinciding with the central axis of the heat exchange component 32. The radius of curvature of the concave surface is set according to the size of the heat exchange component 32 to ensure that the light reflected from the concave surface can be concentrated and illuminate the outer surface of the heat exchange component 32. A reflective layer 61 is laid on the concave surface, and the reflective layer 61 forms a corresponding arc-shaped structure with the concave surface.

[0075] The center of the concave surface corresponds to the center of the heat exchange component 32. The opening of the concave surface faces the heat exchange component 32. When the heat insulation plate 6 is on the far side, the light shines on the reflective layer 61 of the concave surface. After being reflected by the reflective layer 61, the light converges towards the center along the normal direction of the concave surface and acts on the outer surface of the heat exchange component 32, thereby improving the heat absorption efficiency of the heat exchange component 32 for light heat.

[0076] In this embodiment, the concave arc design allows light to converge towards the center after reflection, solving the problems of scattered light reflection and low heat utilization in planar reflective layers. The alignment of the concave axis with the central axis of heat exchange component 32 ensures that the reflected light can be precisely concentrated on the outer surface of heat exchange component 32, avoiding light waste and maximizing the absorption efficiency of light heat by heat exchange component 32.

[0077] When the external ambient temperature is low, the concentrated reflected light can quickly raise the surface temperature of the heat exchange component 32, thereby heating the cooling medium through heat conduction. This prevents the internal electrical components of the charging pile from malfunctioning due to excessive temperature differences caused by the cooling medium being too cold, and also reduces the start-up frequency of the cooling unit, thus lowering energy consumption. The concave structure design eliminates the need for additional light-concentrating devices; the light-concentrating function can be achieved simply by optimizing the surface shape of the heat insulation plate 6. The structure is simple, low-cost, and compatible with the light-shielding and reflective functions of the heat insulation plate 6.

[0078] Furthermore, referring to Figure 5, the entire outer surface of the heat exchange component 2 32 is covered with a heat-absorbing coating. The heat-absorbing coating is evenly spread on each outer surface of the heat exchange component 2 32, including the tube wall / plate surface and the surface of the heat dissipation fins of the heat exchange component 2 32.

[0079] When the heat exchange component 2 32 is in the external state and the heat insulation plate 6 is located on the far side, the light reflected by the reflective layer 61 shines on the heat-absorbing coating of the heat exchange component 2 32. The heat-absorbing coating quickly absorbs the heat in the light and transfers it to the cooling medium inside the heat exchange component 2 32 through heat conduction. When the external ambient temperature is low, the heat-absorbing coating can absorb the radiant heat in the environment, which helps to improve the temperature regulation effect of the cooling medium and ensures the thermal balance of the cooling circuit.

[0080] In this embodiment, the heat-absorbing coating can efficiently absorb the heat from the light reflected by the reflective layer 61, solving the problem of insufficient heat absorption capacity of the surface of the heat exchange component 32. The heat-absorbing coating covers the entire outer surface of the heat exchange component 32, including the heat dissipation fins, increasing the heat absorption area and ensuring that the heat from the light can be quickly and evenly transferred to the cooling medium.

[0081] When the heat exchange component 2 32 is in the external state, the heat-absorbing coating can not only absorb the heat of reflected light, but also absorb the radiant heat in the environment, thus improving the heat exchange efficiency; when the heat exchange component 2 32 is in the internal state, the heat-absorbing coating does not affect its heat exchange with the low-temperature air in the cold air cavity 2.

[0082] Furthermore, referring to Figure 4, an annular groove (not shown in the figure) is formed on the top surface of the base 51 of the adjusting seat 5, and the base 51 is fixedly installed on the lifting end of the lifting assembly 4. The rotating block 52 has a cylindrical structure, and a slider is provided on the bottom surface of the rotating block 52. The slider is embedded in the annular groove of the base 51, and the rotating block 52 achieves horizontal rotation through the sliding engagement between the slider and the base 51.

[0083] The limiting component 53 includes a limiting pin and a positioning hole (not shown in the figure). The positioning hole is evenly opened on the top surface of the rotating block 52 along the circumference of the rotating block 52. The limiting pin slides through the pin hole on the base 51, and the upper end of the limiting pin can be inserted into the positioning hole to limit the position of the rotating block 52. When it is necessary to adjust the horizontal angle of the rotating block 52, the limiting pin is pulled out, the rotating block 52 rotates around the vertical axis, and after adjusting to the target angle, the limiting pin is inserted into the corresponding positioning hole to complete the limiting. As a parallel technical solution, the limiting component 53 is a telescopic top component, which is set on the side wall of the rotating block 52 (see Figure 4). The telescopic end of the telescopic top component is used to press against the upper surface of the base 51 for limiting.

[0084] The two side walls of the swing block 54 are hinged to the top surface of the rotating block 52 via hinge shafts. The axial direction of the hinge shafts is horizontal, allowing the swing block 54 to swing up and down around the hinge shafts. The second heat exchange component 32 is fixedly mounted inside the swing block 54 via a bracket. When the swing block 54 swings, it drives the second heat exchange component 32 to swing synchronously around the hinge shafts, adjusting the vertical tilt angle of the second heat exchange component 32. A locking device, which is a bolt, is provided between the swing block 54 and the rotating block 52. After the swing block 54 is adjusted to the target angle, the hinge shaft is locked by the bolts to fix the position of the swing block 54.

[0085] In this embodiment, the annular groove of the base 51 cooperates with the slider of the rotating block 52 to achieve stable horizontal rotation of the rotating block 52. The limiting pin of the limiting member 53 cooperates with the positioning hole to accurately fix the horizontal position of the rotating block 52, preventing the heat exchange assembly 32 from shifting due to airflow, vibration and other factors during operation, thus ensuring the stability of heat exchange.

[0086] Furthermore, heat exchange assembly 31 and heat exchange assembly 32 can adopt two parallel structures: heat exchange tubes or heat exchange plates, as detailed below:

[0087] The first structure: Both heat exchanger assembly 31 and heat exchanger assembly 32 are heat exchange tubes. The heat exchange tubes have a serpentine structure, with both ends connected to connecting pipes. Several heat dissipation fins are fixedly installed on the heat exchange tubes, evenly arranged along the axial direction of the heat exchange tubes, and perpendicular to the heat exchange tubes. The serpentine heat exchange tube of heat exchanger assembly 31 is laid along the length of the cold air cavity 2 and fixed to the inner wall of the cold air cavity 2; the serpentine heat exchange tube of heat exchanger assembly 32 is fixed to the swing block 54 of the adjusting seat 5, and rotates and swings with the swing block 54.

[0088] The second structure: Both heat exchanger assembly 31 and heat exchanger assembly 32 are heat exchange plates. The heat exchange plate is flat, with a medium channel inside. Both ends of the medium channel are connected to connecting pipes. Heat dissipation fins are fixed on both sides of the heat exchange plate, arranged along the height of the heat exchange plate. The heat exchange plate of heat exchanger assembly 31 is vertically fixed inside the cold air cavity 2, and the surface of the heat exchange plate is perpendicular to the airflow direction inside the cold air cavity 2. The heat exchange plate of heat exchanger assembly 32 is fixed on the swing block 54 of the adjusting seat 5, and the surface of the heat exchange plate can adjust the tilt angle with the swing block 54.

[0089] In both structures, the heat exchange tubes / plates form a closed loop with the cooling pipes. The cooling medium flows through the internal channels of the heat exchange tubes / plates and exchanges heat with the external environment through the tube walls / plate surfaces and heat dissipation fins.

[0090] In this embodiment, the parallel structure of heat exchange tubes and heat exchange plates provides a variety of structural options for the cooling device 3, which can be flexibly adapted to the installation space and power requirements of the charging pile.

[0091] Both structures can form a reliable closed loop with the cooling pipeline to ensure stable flow of the cooling medium. They are also compatible with the state switching function of heat exchange component 1 31 and heat exchange component 2 32. Regardless of which structure is used, the switching between "cooperative heat dissipation" and "independent heat dissipation" can be achieved.

[0092] Furthermore, the bottom surface of the rain cover 7 is flat, and the top surface is curved, with the curved surface sloping outwards to facilitate rainwater sliding off. The rain cover 7 is connected to the pile body 1 via a lifting and telescopic component, which can be a cylinder or similar device.

[0093] In this embodiment, the rain cover 7, together with the opening structure and the lifting function of the heat exchange component 32, form a synergistic protection. The size design of the rain cover 7 can completely cover the top surface and opening of the pile body 1, effectively preventing rainwater from entering the interior of the pile body 1, avoiding problems such as short circuits of electrical components and structural corrosion, and extending the service life of the charging pile.

[0094] The lifting and lowering drive of the rain cover 7 is linked to the state switching of the heat exchange component 2 32. When the heat exchange component 2 32 needs to be raised or lowered, the rain cover 7 automatically rises to avoid it. When the heat exchange component 2 32 is in the internal state, the rain cover 7 lowers to block it.

[0095] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
