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

[0017] 1. A multi-stage heat dissipation structure consisting of an inner box, an inner cooling box, an outer cooling box, a heat collecting box and a cold collecting box is adopted, which can gradually transfer and disperse the heat generated by the device body during the charging process. This design not only improves the heat dissipation efficiency, but also effectively prevents the direct transfer and backflow of heat, ensures that the device body will not overheat, and extends the service life of the equipment. By setting an evaporation chamber 1 between the inner box and the inner cooling box, and setting an evaporation chamber 2 between the inner cooling box and the outer cooling box, which are filled with fluorinated liquid and pentafluoropropane respectively, efficient evaporative cooling is achieved. The evaporation temperature characteristics of different refrigerants ensure the step-by-step transfer of heat, further improving The heat dissipation efficiency is improved, especially in high-load charging scenarios. The fluorinated liquid and pentafluoropropane filled in the evaporation chamber do 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 overfilling. The appropriate filling ratio ensures that the refrigerant is fully in contact with and evaporates in the evaporation chamber, enhancing the heat transfer effect. The inner walls of the inner cooling box and the outer cooling box are provided with a porous metal layer, which increases the surface area and significantly improves the heat conduction efficiency. The porous metal layer also reduces the flow resistance of the refrigerant, ensuring that the refrigerant is fully in contact with and evaporates in the evaporation chamber, further improving the heat dissipation effect.

[0018] 2. Through temperature regulating component 1 and temperature regulating component 2, the system can flexibly switch heating and cooling modes according to the actual needs of the vehicle. When the vehicle needs to be cooled, the cold in the cold collecting box is transferred to the vehicle's air conditioning cooling system or battery cooling system through the inner tube; when the vehicle needs to be heated, the heat in the heat collecting box is transferred to the inside of the vehicle through the inner tube.

This design ensures that the charging cable can maintain a suitable temperature even when charging at high load, extends the service life of the cable, and improves the safety of charging.

[0019] 3. Through the adjustment cover and the adjustment motor, the system can flexibly adjust the opening of the cooling fins according to the actual heat dissipation needs. The adjustment motor drives the adjustment cover to move up and down to increase or decrease the exposed area of ​​the cooling fins, thereby realizing precise control of the heat dissipation rate. The cooling fan adjusts the 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, and enhances the adaptability and reliability of the system. The setting of the cooling fins and the cooling fan provides an additional heat dissipation path to ensure effective heat dissipation even without vehicle heat exchange. The start and stop and speed of the cooling fan are dynamically adjusted by the controller according to the actual heat dissipation needs, which improves the heat dissipation efficiency and flexibility.

[0020] 4. The controller is electrically connected to the equipment body, vehicle control system, regulating motor, solenoid valve, regulating pump and other components, so that the entire heat dissipation and temperature regulation process can be managed automatically. The user does not need manual intervention. The system can automatically optimize the heat dissipation and temperature regulation strategy 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 regulation strategy according to actual needs, ensuring the stability and reliability of the system.

[0036] Three embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0037] Embodiment 1:

[0038] like Figures 1 to 13 As shown, this embodiment provides an intelligent heat dissipation device for a car 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 1 is used to install the equipment body, and a controller is provided inside, which is responsible for the control and management of the entire system. The inner cooling box 2 is located outside the inner box 1, and is used for preliminary cooling of the heat transferred from the inner box 1. The outer cooling box 3 is located outside the inner cooling box 2, and is used for further cooling the heat transferred from the inner cooling box 2. The collector box 4 is fixed on the top of the outer cooling box 3, and is used for collecting and storing excess heat.

[0040] The cold collecting box 5 is fixed at the bottom end of the external cooling box 3 and is used to store the cooled heat transfer 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 to protect the internal components and provide ventilation and heat dissipation functions. One end of the charging cable 7 is fixed to the bottom of the inner box body 1, and the other end passes through the cold collecting box 5 and extends to its outside, and is finally connected to the charging gun 8.

[0042] The charging gun 8 is used to connect to the charging port of the car to realize power transmission. The temperature adjustment component includes an inner tube 9 and an outer tube 10. The outer tube 10 is located on the outside of the inner tube 9. The ends of both tubes close to the cold collecting box 5 are connected to the inside of the cold collecting box 5. A through hole 11 is opened at the end of the inner tube 9 close to the charging gun 8. 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 pipe connected to the inner tube 9 and the outer tube 10, which is connected to the car air-conditioning cooling system and the battery cooling system during charging.

[0043] The cooling fins 14 are fixed on the top of the cold collecting box 5, and a cooling fan is provided inside. The cooling fan is electrically connected to the controller for auxiliary heat dissipation. The shutters are located on the outer box 6 at a position corresponding to the cooling fins 14 for ventilation. The protective cover is located on the top of the outer box 6 for accommodating the adjustment motor 16.

[0044] Working process

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

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

[0047] The heat in the external cooling box 3 is finally gathered in the cold collecting box 5. The heat transfer fluid in the cold collecting box 5 circulates continuously during the charging process, taking away the heat generated by the equipment 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 cooling, the controller communicates with the vehicle control system through the charging gun 8, adjusts the solenoid valve to open the through hole 11, and transfers the cold in the cold collection box 5 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, and transfers the heat in the collector box 4 to the inside of the vehicle 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 the charging process, the controller will start the cooling fan in the cooling fins 14 to accelerate air circulation and help the cooling fins 14 dissipate the heat from the cold collection box 5 to the surrounding environment.

[0051] Whether the cooling fan is started and the speed can be adjusted in real time by the controller according to actual cooling requirements to ensure the best cooling effect.

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

[0053] By connecting the temperature regulating component 1 (inner tube 9 and outer tube 10) with the vehicle air conditioning cooling system and the battery cooling system, full utilization of the heat of the charging pile is achieved, reducing the additional consumption of electrical energy for vehicle 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 in the absence of vehicle heat exchange. The start and stop and speed of the cooling fan are dynamically adjusted by the controller according to actual heat dissipation needs, thereby improving 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 shutters, which is conducive to heat dissipation. The design of the protective cover leaves room for future expansion, so that the device has good adaptability and upgrade potential.

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

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

[0058] Embodiment 2:

[0059] like Figures 1 to 13 As shown, based on Example 1, this embodiment has a more efficient heat transfer mechanism. By setting an evaporation chamber and using a specific refrigerant (fluorinated liquid and pentafluoropropane), the heat dissipation efficiency and the ability to cope with 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 body, and a controller is provided 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 for preliminary cooling of the heat transferred from the inner box body 1. The 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 to further cool the heat transferred from the inner cooling box 2. The evaporation chamber 13 is opened between the inner cooling box 2 and the outer cooling box 3 and is filled with pentafluoropropane 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 external cooling box 3 to collect and store excess heat.

[0063] The cold collecting box 5 is fixed at the bottom end of the external cooling box 3 and is used to store the cooled heat transfer 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 to protect the internal components and provide ventilation and heat dissipation functions. One end of the charging cable 7 is fixed to the bottom of the inner box body 1, and the other end passes through the cold collecting box 5 and extends to its outside, and is finally connected to the charging gun 8. The charging gun 8 is used to connect to the car charging port to realize power transmission.

[0065] The temperature regulating component 1 includes an inner tube 9 and an outer tube 10. The outer tube 10 is located outside the inner tube 9. The ends of both tubes close to the cold collecting box 5 are connected to the inside of the cold collecting box 5. A through hole 11 is opened at the end of the inner tube 9 close to the charging gun 8. 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 pipe connected to the inner tube 9 and the outer tube 10, which is connected to the vehicle air conditioning cooling system and the battery cooling system during charging.

[0066] The cooling fins 14 are fixed on the top of the cold collecting box 5, and a cooling fan is provided inside. The cooling fan is electrically connected to the controller for auxiliary heat dissipation. The shutters are located on the outer box 6 at a position corresponding to the cooling fins 14 for ventilation. The protective cover is located on the top of the outer box 6 for accommodating the adjustment motor 16.

[0067] Working process

[0068] Based on Example 1, this example further improves the heat dissipation efficiency and the ability to cope with 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 to the fluorinated liquid in the evaporation chamber 12 through the inner box 1. The fluorinated liquid absorbs the heat and evaporates rapidly, efficiently transferring the heat from the inner box 1 to the evaporation chamber 12.

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

[0071] Since the fluorinated liquid has a low evaporation temperature, it can effectively absorb heat at a relatively low temperature, thereby ensuring rapid heat transfer and avoiding heat accumulation in the inner box 1 .

[0072] The heat in the inner cooling box 2 is then transferred to the pentafluoropropane in the 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 a smooth transfer of heat from the inner cooling box 2 to the outer cooling box 3 while preventing heat backflow.

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

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

[0076] The fluorinated liquid and pentafluoropropane filled in the evaporation chamber 1 12 and the evaporation chamber 2 13 do not exceed two-thirds of their volumes. This design ensures sufficient space for the refrigerant to evaporate, avoids the problem of uneven heat transfer caused by excessive filling, and thus improves the evaporation efficiency.

[0077] The proper filling ratio also ensures that the refrigerant has enough flow space in the evaporation chamber, promotes full contact and evaporation of the refrigerant, and enhances the heat transfer effect.

[0078] The inner walls of the inner cooling box 2 and the outer cooling box 3 are both provided with a porous metal layer, which increases the surface area and significantly improves the heat conduction efficiency, so that heat can be transferred from the refrigerant to the wall 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 contacted and evaporated in the evaporation chamber, further improving the heat dissipation effect.

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

[0081] Through the arrangement of the evaporation chamber 12 and the evaporation chamber 2 13 , heat can be transferred step by step, avoiding direct transfer and backflow, and ensuring effective management and utilization of heat.

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

[0083] Thanks to the evaporator chamber and refrigerant, the system can manage heat more efficiently and reduce reliance on additional cooling 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 with the vehicle's air conditioning cooling system and battery cooling system, the heat generated by the charging pile can be fully utilized, reducing the additional consumption of electricity for vehicle heating or cooling. Especially in cold climate conditions, heating can significantly save energy. Through the evaporation chamber and specific refrigerant, the system can more efficiently manage the heat generated during the charging process, ensuring that the main body of the equipment will not overheat, thereby extending the service life of the equipment.

[0085] The step-by-step heat transfer mechanism and the porous metal layer design work together to significantly improve the heat dissipation efficiency and ensure the stable operation of the system. This embodiment is not only suitable for 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 suitable for high-load charging scenarios, can more effectively manage the heat generated during the charging process, and through optimized heat transfer mechanism and refrigerant configuration, further improves the heat dissipation efficiency and energy utilization efficiency.

[0087] The arrangement of the evaporation chamber 12 and the evaporation chamber 2 13 enables heat to be transferred step by step, avoiding direct transfer and backflow of heat. The different evaporation temperature characteristics of the fluorinated liquid and pentafluoropropane ensure effective heat transfer and improve heat dissipation efficiency.

[0088] By connecting the temperature regulating component 1 (inner tube 9 and outer tube 10) with the vehicle air conditioning cooling system and the battery cooling system, full utilization of the heat of the charging pile is achieved, reducing the additional consumption of electrical energy for vehicle heating or cooling, especially in cold climate conditions, heating can significantly save energy.

[0089] The setting of the cooling fins 14 and the cooling fan provides an additional heat dissipation path to ensure effective heat dissipation even in the absence of vehicle heat exchange. The start and stop and speed of the cooling fan are dynamically adjusted by the controller according to actual heat dissipation needs, thereby improving heat dissipation efficiency and flexibility.

[0090] 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 shutters, which is conducive to heat dissipation. The design of the protective cover leaves room for future expansion, so that the device has good adaptability and upgrade potential.

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

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

[0093] Embodiment 3:

[0094] like Figures 1 to 13 As shown, based on embodiments 1 and 2, this embodiment further enhances the intelligence and flexibility of the system, and achieves more precise temperature management and higher energy utilization efficiency through components such as an adjustment cover, an adjustment motor, a temperature adjustment component 2, and an adjustment pump. The specific structure is as follows:

[0095] The adjustment cover 15 is slidably connected to the outer end of the heat dissipation fin 14 to adjust the opening between the heat dissipation fin 14 and the outside. The screw is fixedly connected to the top of the adjustment cover 15 and penetrates the outer box body 6 upward.

[0096] The adjusting motor 16 is fixed at the top of the outer box body 6 and is an inner rotor brushless motor, whose rotor is threadedly connected to the screw rod and is used to drive the adjusting cover 15 to move up and down.

[0097] The second temperature regulating component is fixed to one end of the heat collecting 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 first temperature regulating component.

[0098] The solenoid valves are arranged on the temperature regulating component 1 and the temperature regulating component 2, and the multiple solenoid valves are electrically connected to the controller for controlling the flow direction of the heat transfer fluid.

[0099] The regulating pump 17 is fixedly connected to one end of the temperature regulating component 1 located in the heat collecting box 4 and is connected to the inner tube 9 to promote the circulation of the heat transfer liquid in the inner tube 9.

[0100] The regulating pump 18 is fixedly connected to one end of the temperature regulating component 2 located in the cold collecting box 5, and is connected to the outer tube 10, and is used to promote the circulation of the heat transfer liquid in the outer tube 10. The charging cable 7 passes through the regulating pump 18 to ensure that the heat transfer liquid can regulate the temperature of the charging cable 7.

[0101] Working process

[0102] During the charging process, if the vehicle heat exchange and basic heat dissipation mechanisms (such as cooling fans) are still insufficient to dissipate all the heat, the controller will start the regulating motor 16.

[0103] The rotor of the adjusting motor 16 rotates, and the adjusting cover 15 is driven to move up and down through the screw, thereby adjusting the opening between the heat dissipation fins 14 and the outside world. When the heat dissipation rate needs to be increased, the adjusting cover 15 is lifted upward to increase the exposed area of ​​the heat dissipation fins 14; when the heat dissipation rate needs to be reduced, the adjusting cover 15 is moved downward to reduce the exposed area of ​​the heat dissipation fins 14.

[0104] The cooling fan adjusts its speed in real time according to actual cooling needs to ensure the best cooling effect. This dynamic adjustment mechanism enables the system to flexibly adjust the cooling strategy according to ambient temperature and charging load, thereby improving cooling efficiency and energy efficiency.

[0105] The temperature regulating component 1 and the temperature regulating component 2 are respectively located near the cold collecting box 5 and the heat collecting box 4 , and two-way temperature regulation is achieved through the inner pipe 9 and the outer pipe 10 .

[0106] When the vehicle needs cooling, 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's air conditioning cooling system or battery cooling system through the inner tube 9, and the outer tube 10 is used for reflux. At this time, the regulating pump 18 is started to promote the circulation of the heat transfer fluid in the outer tube 10 to ensure 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 collector box 4 is transferred to the inside of the vehicle through the inner tube 9, and the outer tube 10 is used for reflux. At this time, the regulating pump 17 is started to promote the circulation of the heat transfer fluid in the inner tube 9 to ensure efficient heat transfer.

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

[0109] The charging cable 7 passes through the regulating pump 18. The regulating pump 18 is not only responsible for promoting the circulation of the heat transfer liquid in the outer tube 10, but also can open the solenoid valve on the through hole 11 when heat exchange with the vehicle is not needed, so that the heat transfer liquid circulates between the inner tube 9 and the outer tube 10, thereby regulating the temperature of the charging cable 7 and preventing the charging cable 7 from overheating.

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

[0111] By adjusting the cover 15 and the motor 16, the system can flexibly adjust the opening of the cooling fins 14 according to the actual heat dissipation requirements 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, thereby enhancing the adaptability and reliability of the system.

[0112] The setting of temperature regulation component 1 and temperature regulation component 2 realizes dual-path 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 use of the heat generated by the charging pile and reduces the additional consumption of electricity for vehicle heating or cooling, especially in cold climate conditions, heating can significantly save energy.

[0113] Regulating pump 1 17 and regulating pump 2 18 ensure efficient circulation of the heat transfer fluid in the inner tube 9 and the outer tube 10, thereby 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 maintains a suitable temperature during high-load charging, thereby extending the service life of the cable and improving the safety of charging.

[0114] The electrical connection between the controller and the regulating motor 16, the solenoid valve, the regulating pump 1 17 and the regulating pump 2 18 enables the entire heat dissipation and temperature regulation process to be managed automatically without manual intervention by the user, thereby improving 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 charging load, ensuring the efficient operation of the system.

[0116] 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 shutters, which is conducive to heat dissipation. The design of the protective cover leaves room for future expansion, so that the device has good adaptability and upgrade potential.

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

[0118] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
