Description

Technical Field

[0001] The intelligent heat dissipation device for vehicle charging piles of the present invention particularly relates to an intelligent heat dissipation device for vehicle charging piles applied to the field of vehicle charging technology. Background Art

[0002] With the popularization of electric vehicles, the demand for charging piles has increased sharply. However, during high-load charging, charging piles generate a large amount of heat. If this heat cannot be effectively managed, it will not only affect the service life of the equipment but also may lead to safety hazards. Existing charging pile heat dissipation solutions mainly rely on fans, water cooling systems, or passive heat dissipation structures. However, these methods have certain limitations and cannot meet the growing demand for efficient heat dissipation and energy utilization.

[0003] Chinese invention patent CN112248846B discloses an auxiliary heat dissipation device for vehicle charging piles, including a first box body, a forced cooling device, a position adjustment device, a sun protection device, and a wiping device. By adjusting the positions of the motor and the impeller through the position adjustment device, heat absorption is made uniform; the sun protection device plays a heat insulation role; the wiping device and the forced cooling device provide further heat dissipation functions. Although this design provides multi-level heat dissipation functions, it mainly relies on mechanical adjustment and external cooling devices, and the heat dissipation efficiency is still limited. Especially in high-load charging scenarios, the use of the forced cooling device and the wiping device increases additional energy consumption, affecting the overall energy efficiency of the system. The presence of multiple mechanical components increases the complexity and maintenance difficulty of the system and reduces the reliability.

[0004] Chinese invention patent CN112455258B discloses a heat dissipation mechanism for new energy vehicle charging piles, including a housing, a water tank, an air pump, a vortex cooler, etc. By driving the water flow through a water pump, the heat generated inside the charging pile is absorbed, and the temperature of the high-temperature water flow flowing back into the water tank is reduced by cold air to form a cooling and heat dissipation cycle. At the same time, the sealed design prevents external dust from entering, and the wire placement ring provided at the bottom can effectively organize the charging wires. This design mainly relies on the cooling method combining water cooling and an air pump, lacks a flexible temperature adjustment mechanism, and is difficult to meet the heat dissipation requirements under different environmental conditions. Although a heat dissipation cycle is achieved, the heat generated by the charging pile is not fully utilized, resulting in energy waste. Especially in cold climate conditions, the heat cannot be used for vehicle heating, and the response speed of the water cooling system is slow and cannot quickly adapt to changes in the charging load, affecting the heat dissipation effect. Summary of the Invention

[0007] In the above-mentioned intelligent heat dissipation device for electric vehicle chargers, through a multi-stage heat dissipation structure and an evaporative cooling mechanism, heat is transferred and dispersed step by step to ensure that the main body of the device does not overheat, extending the service life of the device. The dual-channel temperature regulation system flexibly switches between heating and cooling modes according to the actual needs of the vehicle, maximizing the utilization of the heat generated by the charger and reducing the additional power consumption for vehicle heating or cooling. Through the adjustment cover and the adjustment motor, the opening degree of the heat dissipation fins is dynamically adjusted according to the actual heat dissipation requirements, achieving precise control of the heat dissipation rate and improving the flexibility of heat dissipation.

The outer box protects the internal components and provides good ventilation conditions. The protective cover leaves room for future expansion. The modular design is convenient for installation and maintenance, reducing the maintenance cost and improving the overall reliability of the system. It is suitable for high-load charging scenarios, ensuring the stable operation of the charger during long-term and high-current charging, extending the service life of the device, reducing the maintenance cost, and being widely applied in urban public parking lots, shopping malls, office buildings, etc. Through intelligent heat dissipation and temperature regulation, the user experience is improved, and energy waste is reduced. It is suitable for private residences. By optimizing energy utilization, the household electricity cost is reduced. Especially in cold climate conditions, the heat generated by the charger is used to heat the vehicle, saving heating costs. By optimizing energy utilization, the additional power consumption for vehicle heating or cooling is reduced. Especially in cold climate conditions, heating can significantly save energy and reduce the charging cost of users.

An evaporation chamber two is provided between the inner cooling box and the outer cooling box, and the evaporation chamber two is filled with pentafluoropropane.

[0009] The top of the cold collection box is fixedly connected with heat dissipation fins, and a heat dissipation fan is fixedly connected inside the heat dissipation fins, and the heat dissipation fan is electrically connected to the controller.

[0010] The outer end of the heat dissipation fins is slidably connected with an adjustment cover. The top of the adjustment cover is fixedly connected with a screw rod, and the screw rod penetrates upward through the outer box. At the position corresponding to the screw rod at the top of the outer box, an adjustment motor is fixedly connected. The adjustment motor is an inner-rotor brushless motor, and the rotor of the adjustment motor is threadedly connected to the screw rod.

[0011] At the position corresponding to the heat dissipation fins on the outer box body, there are louvers for ventilation, and at the position corresponding to the adjustment motor at the top of the outer box body, there is a protective cover fixedly connected for accommodating the adjustment motor.

[0012] At one end of the heat collection box close to the charging gun, there is a second temperature adjustment component fixedly connected. The second temperature adjustment component also includes an inner pipe and an outer pipe. The inner pipe and the outer pipe on the first temperature adjustment component are respectively communicated with the inner pipe and the outer pipe on the second temperature adjustment component.

[0013] On both the first temperature adjustment component and the second temperature adjustment component, there are solenoid valves, and multiple solenoid valves are all electrically connected to the controller. At one end of the first temperature adjustment component and the second temperature adjustment component located in the heat collection box and the cold collection box, there are respectively a first adjustment pump and a second adjustment pump fixedly connected.

[0014] The first adjustment pump is communicated with the inner pipe on the first temperature adjustment component, the second adjustment pump is communicated with the outer pipe on the second temperature adjustment component, the charging cable penetrates through the second adjustment pump, and both the first adjustment pump and the second adjustment pump are electrically connected to the controller.

[0015] The filling of the fluorinated liquid and pentafluoropropane in the first evaporation chamber and the second evaporation chamber does not exceed two-thirds of their volumes. Porous metal layers are provided on the inner walls of the inner cooling box and the outer cooling box.

[0016] In summary, the present application has the following beneficial effects:

[0017] 1. A multi-stage heat dissipation structure composed of an inner box body, an inner cooling box, an outer cooling box, a heat collection box, and a cold collection box is adopted, which can gradually transfer and disperse the heat generated by the equipment main body during the charging process. This design not only improves the heat dissipation efficiency but also effectively prevents the direct transfer and reflux of heat, ensuring that the equipment main body will not overheat and extending the service life of the equipment. By setting a first evaporation chamber between the inner box body and the inner cooling box and a second evaporation chamber between the inner cooling box and the outer cooling box, and filling fluorinated liquid and pentafluoropropane respectively, efficient evaporation cooling is achieved. The evaporation temperature characteristics of different refrigerants ensure the gradual transfer of heat, further improving the heat dissipation efficiency, especially being particularly prominent in high-load charging scenarios. The filling of the fluorinated liquid and pentafluoropropane in the evaporation chamber does not exceed two-thirds of the volume, ensuring sufficient space for the refrigerant to evaporate and avoiding the problem of uneven heat transfer caused by excessive filling. The appropriate filling ratio ensures that the refrigerant fully contacts and evaporates in the evaporation chamber, enhancing the heat transfer effect. Porous metal layers are provided on the inner walls of the inner cooling box and the outer cooling box, increasing the surface area and significantly improving the heat conduction efficiency. The porous metal layer also reduces the flow resistance of the refrigerant, ensuring that the refrigerant fully contacts and evaporates in the evaporation chamber, further enhancing the heat dissipation effect.

[0018] 2. Through the temperature adjustment component one and the temperature adjustment component two, the system can flexibly switch between the heating and cooling modes according to the actual needs of the vehicle. When the vehicle needs cooling, the cold in the cold storage box is transferred to the vehicle's air-conditioning cooling system or battery cooling system through the inner tube; when the vehicle needs heating, the heat in the heat collection box is transferred to the vehicle interior through the inner tube. This design maximally utilizes the heat generated by the charging pile, reducing the additional power consumption for vehicle heating or cooling. Especially for heating in cold climate conditions, it can significantly save energy. The charging cable passes through the regulating pump two. The regulating pump two not only drives the heat-conducting liquid to circulate in the outer tube but also, when heat exchange with the vehicle is not required, makes the heat-conducting liquid circulate between the inner tube and the outer tube by opening the solenoid valve on the through-hole to adjust the temperature of the charging cable and prevent the charging cable from overheating. This design ensures that the charging cable can maintain an appropriate temperature even during high-load charging, extends the service life of the cable, and improves the charging safety.

[0019] 3. Through the adjusting cover and the adjusting motor, the system can flexibly adjust the opening degree of the heat dissipation fins according to the actual heat dissipation needs. The adjusting motor drives the adjusting cover to move up and down, increasing or decreasing the exposed area of the heat dissipation fins, thereby achieving precise control of the heat dissipation rate. The cooling fan adjusts the rotation speed in real time according to the actual heat dissipation needs to ensure the best heat dissipation effect. This dynamic adjustment mechanism not only improves the heat dissipation efficiency but also can adapt to different environmental conditions and charging loads, enhancing the adaptability and reliability of the system. The setting of the heat dissipation fins and the cooling fan provides an additional heat dissipation path to ensure effective heat dissipation even without vehicle heat exchange. The start-stop and rotation speed of the cooling fan are dynamically adjusted by the controller according to the actual heat dissipation needs, improving the heat dissipation efficiency and flexibility.

[0020] 4. The controller is electrically connected to components such as the device main body, the vehicle control system, the adjusting motor, the solenoid valve, and the regulating pump, enabling the entire heat dissipation and temperature adjustment process to be automatically managed without manual intervention by the user. The system can automatically optimize the heat dissipation and temperature adjustment strategies according to the ambient temperature and charging load, ensuring the efficient operation of the system. Through real-time monitoring and adjustment, the system can automatically optimize the heat dissipation and temperature adjustment strategies according to the actual needs, ensuring the stability and reliability of the system. The intelligent control not only enhances the user experience but also reduces the maintenance cost and extends the service life of the device. Description of the Drawings

[0036] The following will describe three embodiments of this application in detail with reference to the accompanying drawings.

[0037] Embodiment 1:

[0038] As Figures 1 to 13 shown, this embodiment provides an intelligent heat dissipation device for an electric vehicle charging pile, which is designed to effectively manage the heat generated during the charging process and interact with the vehicle through a simple heat exchange mechanism. The device includes the following main components:

[0039] The inner box body 1 is used to install the equipment main body, and a controller is arranged inside, which is responsible for the control and management of the whole system. The inner cooling box 2 is located outside the inner box body 1 and is used to initially cool the heat transferred from the inner box body 1. The outer cooling box 3 is located outside the inner cooling box 2 and further cools the heat transferred from the inner cooling box 2. The heat collecting box 4 is fixed on the top of the outer cooling box 3 and is used to collect and store the redundant heat.

[0040] The cold collecting box 5 is fixed at the bottom end of the outer cooling box 3 and is used to store the cooled heat-conducting liquid.

[0041] The outer box body 6 covers the outside of the outer cooling box 3, the heat collecting box 4 and the cold collecting box 5, protects the internal components and provides ventilation and heat dissipation functions. One end of the charging cable 7 is fixed at the bottom end of the inner box body 1, and the other end passes through the cold collecting box 5 and extends to the outside thereof, and finally is connected to the charging gun 8.

[0042] The charging gun 8 is used to connect with the vehicle charging port to realize electric energy transmission. The temperature regulating component I includes an inner tube 9 and an outer tube 10. The outer tube 10 is located outside the inner tube 9. One ends of both of them close to the cold collecting box 5 are communicated with the inside of the cold collecting box 5. One end of the inner tube 9 close to the charging gun 8 is provided with a through hole 11, and a solenoid valve is fixedly connected to the through hole 11, and the solenoid valve is electrically connected to the controller. The charging gun 8 is provided with a pipeline communicated with the inner tube 9 and the outer tube 10, and is communicated with the vehicle air-conditioning cooling system and the battery cooling system during charging.

[0043] The heat dissipation fins 14 are fixed on the top of the cold collecting box 5, and a heat dissipation fan is arranged inside. The heat dissipation fan is electrically connected to the controller and is used for assisting heat dissipation. The louvers are located at the position of the outer box body 6 corresponding to the heat dissipation fins 14 and are used for ventilation. The protective cover is located on the top of the outer box body 6 and is used to accommodate the adjusting motor 16.

[0044] Working process

[0045] The user inserts the charging gun 8 into the vehicle charging port to start the charging process. At this time, the charging cable 7 transmits electric energy to the vehicle through the inner box body 1.

[0046] During the charging process, the heat generated by the equipment main body is first transferred from the inner box body 1 to the inner cooling box 2. After the inner cooling box 2 initially absorbs this heat, it then transfers the heat to the outer cooling box 3 for further cooling.

[0047] The heat in the outer cooling box 3 finally converges into the cold collecting box 5. The heat-conducting liquid in the cold collecting box 5 continuously circulates during the charging process, taking away the heat generated by the equipment main body. At the same time, part of the heat will be transferred to the heat collecting box 4 for storage.

[0048] When the vehicle needs to be cooled, the controller communicates with the vehicle control system through the charging gun 8, adjusts the solenoid valve to open the through hole 11, so that the cold in the cold collection box 5 is transferred to the vehicle's air-conditioning cooling system or battery cooling system through the inner tube 9, and the outer tube 10 is used for reflux.

[0049] When the vehicle needs to be heated, the controller also communicates with the vehicle control system through the charging gun 8, adjusts the solenoid valve to close the through hole 11, so that the heat in the heat collection box 4 is transferred to the vehicle interior through the inner tube 9, and the outer tube 10 is used for reflux.

[0050] If the heat exchange with the vehicle is not sufficient to consume all the heat generated during charging, the controller will start the cooling fan in the cooling fins 14 to accelerate the air flow and help the cooling fins 14 dissipate the heat on the cold collection box 5 to the surrounding environment.

[0051] Whether the cooling fan starts or not and its rotation speed can be adjusted in real time by the controller according to the actual heat dissipation requirements to ensure the best heat dissipation effect.

[0052] The multi-stage heat dissipation structure composed of the inner box body 1, the inner cooling box 2, the outer cooling box 3, the cold collection box 5 and the heat collection box 4 can effectively manage the heat generated during charging, ensure that the main body of the equipment does not overheat, and extend the service life of the equipment.

[0053] Through the connection of the temperature adjustment component one (the inner tube 9 and the outer tube 10) to the vehicle air-conditioning cooling system and battery cooling system, the full utilization of the heat of the charging pile is realized, reducing the additional power consumption of the vehicle for heating or cooling. Especially in cold climate conditions, heating can significantly save energy.

[0054] The setting of the cooling fins 14 and the cooling fan provides an additional heat dissipation path to ensure effective heat dissipation even without vehicle heat exchange. The start / stop and rotation speed of the cooling fan are dynamically adjusted by the controller according to the actual heat dissipation requirements, improving the heat dissipation efficiency and flexibility.

[0055] The outer box body 6 not only protects the internal components from the influence of the external environment, but also provides good ventilation conditions through the louvers, which is beneficial to heat dissipation. The design of the protective cover leaves room for future expansion, making the device have better adaptability and upgrade potential.

[0056] The electrical connection of the controller to the main body of the equipment and the vehicle control system enables the entire heat dissipation process to be automatically managed without manual intervention by the user, improving the user experience and the reliability of the system.

[0057] Through the above design, this embodiment provides a basic intelligent heat dissipation device with a simple structure, reliable performance and easy maintenance, which is suitable for most application scenarios of electric vehicle charging piles.

[0058] Embodiment 2:

[0059] As Figures 1 to 13 shown, based on Embodiment 1, this embodiment provides a more efficient heat transfer mechanism. By setting up an evaporation chamber and using specific refrigerants (fluorinated liquid and pentafluoropropane), the heat dissipation efficiency and the ability to handle higher load charging requirements are further improved. The specific structure is as follows:

[0060] The inner box body 1 is used to install the equipment main body, and a controller is arranged inside, which is responsible for the control and management of the entire system. The inner cooling box 2 is located outside the inner box body 1 and is used to initially cool the heat transferred from the inner box body 1. The first evaporation chamber 12 is opened between the inner box body 1 and the inner cooling box 2 and is filled with fluorinated liquid, which is used to absorb the heat transferred from the inner box body 1 and transfer it to the inner cooling box 2.

[0061] The outer cooling box 3 is located outside the inner cooling box 2 and further cools the heat transferred from the inner cooling box 2. The second evaporation chamber 13 is opened between the inner cooling box 2 and the outer cooling box 3 and is filled with pentafluoropropane, which is used to absorb the heat transferred from the inner cooling box 2 and transfer it to the outer cooling box 3.

[0062] The heat collecting box 4 is fixed on the top of the outer cooling box 3 and is used to collect and store the excess heat.

[0063] The cold collecting box 5 is fixed at the bottom of the outer cooling box 3 and is used to store the cooled heat conducting liquid.

[0064] The outer box body 6 covers the outside of the outer cooling box 3, the heat collecting box 4 and the cold collecting box 5, protects the internal components and provides ventilation and heat dissipation functions. One end of the charging cable 7 is fixed at the bottom of the inner box body 1, and the other end passes through the cold collecting box 5 and extends to the outside thereof, and finally is connected to the charging gun 8. The charging gun 8 is used to connect with the vehicle charging port to realize power transmission.

[0065] The first temperature regulating component includes an inner tube 9 and an outer tube 10. The outer tube 10 is located outside the inner tube 9. One end of both of them close to the cold collecting box 5 is connected to the inside of the cold collecting box 5. One end of the inner tube 9 close to the charging gun 8 is provided with a through hole 11, and a solenoid valve is fixedly connected to the through hole 11, and the solenoid valve is electrically connected to the controller. The charging gun 8 is provided with a pipeline connected to the inner tube 9 and the outer tube 10, and is connected to the vehicle air conditioning cooling system and the battery cooling system during charging.

[0066] The heat dissipation fins 14 are fixed on the top of the cold collecting box 5, and a heat dissipation fan is arranged inside. The heat dissipation fan is electrically connected to the controller and is used for assisting heat dissipation. The louvers are located at the position on the outer box body 6 corresponding to the heat dissipation fins 14 and are used for ventilation. The protective cover is located on the top of the outer box body 6 and is used to accommodate the adjusting motor 16.

[0067] Working process

[0068] Based on Embodiment 1, this embodiment further improves the heat dissipation efficiency and the ability to handle higher load charging requirements through an evaporation chamber and specific refrigerants (fluorinated liquid and pentafluoropropane).

[0069] During the charging process, the heat generated by the device body is first transferred from the inner box 1 to the fluorinated liquid in the first evaporation chamber 12. After absorbing the heat, the fluorinated liquid quickly evaporates, efficiently transferring the heat from the inner box 1 to the first evaporation chamber 12.

[0070] The evaporated fluorinated liquid vapor rises in the first evaporation chamber 12 and condenses back into a liquid through the wall surface of the inner cooling box 2. During this process, the heat is transferred to the inner cooling box 2, achieving the first step-by-step heat transfer.

[0071] Due to the low evaporation temperature of the fluorinated liquid, it can effectively absorb heat at a relatively low temperature, ensuring rapid heat transfer and preventing heat accumulation in the inner box 1.

[0072] The heat in the inner cooling box 2 is then transferred to the pentafluoropropane in the second evaporation chamber 13. The evaporation temperature of pentafluoropropane is higher than that of the fluorinated liquid, so it can absorb the heat from the inner cooling box 2 and evaporate, further transferring the heat to the outer cooling box 3.

[0073] The evaporation process of pentafluoropropane is also rapid and efficient, ensuring smooth heat transfer from the inner cooling box 2 to the outer cooling box 3 and preventing heat backflow.

[0074] The evaporated pentafluoropropane vapor rises in the second evaporation chamber 13 and condenses back into a liquid through the wall surface of the outer cooling box 3. During this process, the heat is transferred to the outer cooling box 3, completing the second step-by-step heat transfer.

[0075] The outer cooling box 3 further cools this heat and finally transfers the heat to the cold collection box 5 and the heat collection box 4 for storage or dissipation.

[0076] The fluorinated liquid and pentafluoropropane filled in the first evaporation chamber 12 and the second evaporation chamber 13 do not exceed two-thirds of their volumes. This design ensures sufficient space for the refrigerants to evaporate, avoids the problem of uneven heat transfer caused by overfilling, and thus improves the evaporation efficiency.

[0077] The appropriate filling ratio also ensures that the refrigerants have sufficient flow space in the evaporation chamber, promotes full contact and evaporation of the refrigerants, and enhances the heat transfer effect.

[0078] Porous metal layers are provided on the inner walls of the inner cooling box 2 and the outer cooling box 3. The porous metal layers increase the surface area and significantly improve the heat conduction efficiency, enabling heat to be transferred from the refrigerant to the wall surface of the cooling box more quickly.

[0079] The porous metal layer also reduces the flow resistance of the refrigerant, ensuring that the refrigerant is fully in contact with and evaporated in the evaporation chamber, further enhancing the heat dissipation effect.

[0080] The design of the porous metal layer can also improve the distribution uniformity of the refrigerant, avoiding problems such as local overheating or insufficient cooling, and ensuring the stable operation of the entire system.

[0081] Through the settings of evaporation chamber one 12 and evaporation chamber two 13, heat can be transferred step by step, avoiding direct transfer and reflux, and ensuring the effective management and utilization of heat.

[0082] This step-by-step transfer mechanism not only improves the heat dissipation efficiency, but also extends the service life of the equipment and reduces the maintenance cost.

[0083] Due to the evaporation chamber and the refrigerant, the system can manage heat more efficiently, reducing the dependence on additional heat dissipation equipment. Especially in high-load charging scenarios, this design can significantly reduce energy consumption and improve the overall energy efficiency of the system.

[0084] By connecting to the vehicle air-conditioning cooling system and the battery cooling system, the heat generated by the charging pile can be fully utilized, reducing the additional power consumption for vehicle heating or cooling. Especially in cold climate conditions, heat supply can significantly save energy. Through the evaporation chamber and specific refrigerant, the system can manage the heat generated during the charging process more efficiently, ensuring that the main body of the equipment does not overheat and extending the service life of the equipment.

[0085] The combined action of the step-by-step heat transfer mechanism and the design of the porous metal layer significantly improves the heat dissipation efficiency and ensures the stable operation of the system. This embodiment is not only applicable to high-load charging scenarios, but can also be flexibly adjusted according to actual needs. For example, in the future, the performance of the system can be further improved by adding more evaporation chambers or optimizing the refrigerant configuration. The design of the protective cover leaves room for future expansion, making the device have good adaptability and upgrade potential.

[0086] Through the above design, this embodiment provides an enhanced intelligent heat dissipation device with a more complex structure and superior performance, which is applicable to high-load charging scenarios, can manage the heat generated during the charging process more effectively, and further improves the heat dissipation efficiency and energy utilization efficiency through an optimized heat transfer mechanism and refrigerant configuration.

[0087] The settings of evaporation chamber one 12 and evaporation chamber two 13 enable heat to be transferred step by step, avoiding direct heat transfer and reflux. The different evaporation temperature characteristics of the fluorinated liquid and pentafluoropropane ensure the effective transfer of heat and improve the heat dissipation efficiency.

[0088] By connecting the temperature regulation component one (inner tube 9 and outer tube 10) to the vehicle air conditioning cooling system and the battery cooling system, the heat of the charging pile is fully utilized, reducing the additional power consumption for vehicle heating or cooling. Especially in cold climate conditions, heat supply can significantly save energy.

[0089] The provision of the heat dissipation fins 14 and the heat dissipation fan provides an additional heat dissipation path, ensuring effective heat dissipation even without vehicle heat exchange. The start / stop and rotation speed of the heat dissipation fan are dynamically adjusted by the controller according to the actual heat dissipation requirements, improving the heat dissipation efficiency and flexibility.

[0090] The outer box body 6 not only protects the internal components from the external environment but also provides good ventilation conditions through the louvers, which is beneficial to heat dissipation. The design of the protective cover leaves room for future expansion, making the device have better adaptability and upgrade potential.

[0091] The electrical connection of the controller to the device main body and the vehicle control system enables the entire heat dissipation process to be automatically managed without manual intervention by the user, enhancing the user experience and the reliability of the system.

[0092] Through the above design, this embodiment provides an enhanced intelligent heat dissipation device with a more complex structure and superior performance, suitable for high-load charging scenarios. It can more effectively manage the heat generated during the charging process and further improve the heat dissipation efficiency and energy utilization efficiency through an optimized heat transfer mechanism and refrigerant configuration.

[0093] Embodiment 3:

[0094] As Figures 1 to 13 shown, based on Embodiments 1 and 2, this embodiment further enhances the intelligence and flexibility of the system. Through components such as the adjustment cover, adjustment motor, temperature regulation component two, and adjustment pump, more precise temperature management and higher energy utilization efficiency are achieved. The specific structure is as follows:

[0095] The adjustment cover 15 is slidably connected to the outer end of the heat dissipation fins 14 for adjusting the opening degree between the heat dissipation fins 14 and the outside. The screw rod is fixedly connected to the top of the adjustment cover 15 and penetrates upward through the outer box body 6.

[0096] The adjustment motor 16 is fixed to the top of the outer box body 6 and is a brushless inner rotor motor. Its rotor is threadedly connected to the screw rod for driving the up and down movement of the adjustment cover 15.

[0097] The temperature regulation component two is fixed to one end of the heat collection box 4 close to the charging gun 8 and also includes an inner tube 9 and an outer tube 10, and is connected to the inner tube 9 and the outer tube 10 on the temperature regulation component one.

[0098] The solenoid valves are arranged on the first temperature regulating component and the second temperature regulating component, and multiple solenoid valves are electrically connected to the controller to control the flow direction of the heat-conducting liquid.

[0099] The first regulating pump 17 is fixedly connected to one end of the first temperature regulating component located in the heat collection box 4 and is communicated with the inner pipe 9 to push the heat-conducting liquid to circulate in the inner pipe 9.

[0100] The second regulating pump 18 is fixedly connected to one end of the second temperature regulating component located in the cold collection box 5 and is communicated with the outer pipe 10 to push the heat-conducting liquid to circulate in the outer pipe 10. The charging cable 7 passes through the second regulating pump 18 to ensure that the heat-conducting liquid can adjust the temperature of the charging cable 7.

[0101] Working process

[0102] During the charging process, if it is still not sufficient to consume all the heat through vehicle heat exchange and basic heat dissipation mechanisms (such as the radiator fan), the controller will start the regulating motor 16.

[0103] The rotor of the regulating motor 16 rotates, driving the regulating cover 15 to move up and down through the screw, thereby adjusting the opening degree between the heat dissipation fins 14 and the outside. When it is necessary to increase the heat dissipation rate, the regulating cover 15 is lifted upward to increase the exposed area of the heat dissipation fins 14; when it is necessary to reduce the heat dissipation rate, the regulating cover 15 moves downward to reduce the exposed area of the heat dissipation fins 14.

[0104] The radiator fan adjusts the rotation speed in real time according to the actual heat dissipation requirements to ensure the best heat dissipation effect. This dynamic regulation mechanism enables the system to flexibly adjust the heat dissipation strategy according to the ambient temperature and charging load, improving the heat dissipation efficiency and energy efficiency.

[0105] The first temperature regulating component and the second temperature regulating component are respectively located near the cold collection box 5 and the heat collection box 4, and dual-channel temperature regulation is achieved through the inner pipe 9 and the outer pipe 10.

[0106] When the vehicle needs to be cooled, the controller adjusts the solenoid valve to open the through hole 11, so that the cold in the cold collection box 5 is transferred to the vehicle air-conditioning cooling system or battery cooling system through the inner pipe 9, and the outer pipe 10 is used for reflux. At this time, the second regulating pump 18 is started to push the heat-conducting liquid to circulate in the outer pipe 10 to ensure the efficient transfer of cold.

[0107] When the vehicle needs to be heated, the controller adjusts the solenoid valve to close the through hole 11, so that the heat in the heat collection box 4 is transferred to the vehicle interior through the inner pipe 9, and the outer pipe 10 is used for reflux. At this time, the first regulating pump 17 is started to push the heat-conducting liquid to circulate in the inner pipe 9 to ensure the efficient transfer of heat.

[0108] Through dual-channel temperature regulation, the system can flexibly switch between heating and cooling modes according to the actual needs of the vehicle, maximizing the utilization of the heat generated by the charging pile and reducing the additional power consumption for vehicle heating or cooling.

[0109] The charging cable 7 passes through the regulating pump two 18. The regulating pump two 18 is not only responsible for pushing the heat-conducting liquid to circulate in the outer tube 10, but also can, when heat exchange with the vehicle is not required, make the heat-conducting liquid circulate between the inner tube 9 and the outer tube 10 by opening the solenoid valve on the through hole 11 to regulate the temperature of the charging cable 7 and prevent the charging cable 7 from overheating.

[0110] This design ensures that the charging cable 7 can maintain an appropriate temperature even during high-load charging, extending the service life of the cable and improving the safety of charging.

[0111] Through the regulating cover 15 and the regulating motor 16, the system can flexibly adjust the opening degree of the heat dissipation fins 14 according to the actual heat dissipation needs to ensure the best heat dissipation effect. This dynamic regulation mechanism not only improves the heat dissipation efficiency, but also can adapt to different environmental conditions and charging loads, enhancing the adaptability and reliability of the system.

[0112] The settings of the temperature regulation component one and the temperature regulation component two achieve dual-channel temperature regulation, ensuring that the system can flexibly switch between heating and cooling modes according to the actual needs of the vehicle. This design maximizes the utilization of the heat generated by the charging pile and reduces the additional power consumption for vehicle heating or cooling. Especially for heating in cold climate conditions, energy can be significantly saved.

[0113] The regulating pump one 17 and the regulating pump two 18 ensure the efficient circulation of the heat-conducting liquid in the inner tube 9 and the outer tube 10, improving the speed and efficiency of heat transfer. This design not only improves the response speed of the system, but also ensures that the charging cable 7 can maintain an appropriate temperature during high-load charging, extending the service life of the cable and improving the safety of charging.

[0114] The controller is electrically connected to the regulating motor 16, the solenoid valve, the regulating pump one 17 and the regulating pump two 18, enabling the entire heat dissipation and temperature regulation process to be automatically managed without manual intervention by the user, enhancing the user experience and the reliability of the system.

[0115] Through real-time monitoring and adjustment, the system can automatically optimize the heat dissipation and temperature regulation strategies according to the ambient temperature and the charging load, ensuring the efficient operation of the system.

[0116] The outer box 6 not only protects the internal components from the influence of the external environment, but also provides good ventilation conditions through the louvers, which is conducive to heat dissipation. The design of the protective cover leaves room for future expansion, making the device have good adaptability and upgrade potential.

[0117] Through the above design, this embodiment provides a comprehensive intelligent heat dissipation device with a complex structure and excellent performance, which is applicable to various charging scenarios, can more effectively manage the heat generated during charging, and further improves the heat dissipation efficiency and energy utilization efficiency through an intelligent temperature regulation and heat dissipation mechanism.

[0118] Combined with the current actual requirements, the above implementation manner adopted in this application, the scope of protection is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
