[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] The following is for reference. Figures 1-3 A charging cooling system 100 according to an embodiment of the present invention is described.

[0028] like Figures 1-3 As shown, the charging and cooling system 100 according to an embodiment of the present invention includes a charging device 10 and a cooling device 20.

[0029] The charging device 10 includes a charging gun 11 and a charging base assembly 12. The charging gun 11 is suitable for installation in a charging pile, and the charging base assembly 12 is suitable for installation in a vehicle. The charging gun 11 can be electrically connected to the charging base assembly 12 to charge the charging base assembly 12. The cooling device 20 includes an air compressor 21, a first heat exchanger 22, a second heat exchanger 23, and a drive pump 30. The refrigerant flow channels 231 of the air compressor 21, the first heat exchanger 22, and the second heat exchanger 23 form a refrigerant circulation loop 44. The cooling medium flow channels 232 of the drive pump 30 and the second heat exchanger 23 and the charging device 10 form a cooling medium circulation loop 45.

[0030] The charging device 10 includes a charging gun 11 and a charging base assembly 12. The charging gun 11 can be installed on a charging pile and electrically connected to the charging pile. Specifically, the charging gun 11 can be detachably placed on the charging pile. The charging gun 11 and the charging pile can be connected in a manner that includes, but is not limited to, snap-fit ​​or magnetic connection. The charging base assembly 12 can be installed on the vehicle. The charging gun 11 can cooperate with the charging base assembly 12 to make the charging gun 11 electrically connected to the charging base assembly 12 so that the charging gun 11 can supply power to the charging base assembly 12. As some embodiments of this application, the charging gun 11 can be electrically connected to the charging base 121 through a connector.

[0031] As some embodiments of this application, the cooling device 20 is located at the charging pile and outside the vehicle. As some embodiments of this application, the cooling device 20 is located at the charging pile.

[0032] The cooling device 20 includes an air compressor 21, a first heat exchanger 22, a second heat exchanger 23, and a drive pump 30. The refrigerant flow channels 231 of the air compressor 21, the first heat exchanger 22, and the second heat exchanger 23 are connected by pipelines to form a refrigerant circulation loop 44, in which the refrigerant can circulate.

[0033] The drive pump 30, the cooling medium flow channel 232 of the second heat exchanger 23, and the charging device 10 are connected by pipelines to form a cooling medium circulation loop 45, in which the cooling medium can circulate and exchange heat.

[0034] As some embodiments of this application, the refrigerant in the refrigerant circulation loop 44 can be, but is not limited to, R134a (1,1,1,2-tetrafluoroethane), R1234YF (2,3,3,3-tetrafluoropropylene), etc. As some embodiments of this application, the cooling medium flowing in the cooling medium circulation loop 45 can be cooling water, which can be, but is not limited to, an aqueous solution of ethylene glycol, an aqueous solution of propylene glycol, etc.

[0035] As some embodiments of this application, the cooling device 20 also includes a first expansion valve 24, which is located in the refrigerant circulation loop 44. The refrigerant circulation loop 44 can exchange heat with the cooling medium circulation loop 45, and the refrigerant circulation loop 44 can achieve cooling. The working principle of the refrigerant circulation loop 44 can be understood as the working principle of a vehicle air conditioner. The refrigerant is compressed into a high-temperature and high-pressure gaseous refrigerant under the action of the air compressor 21, and then flows through the first heat exchanger 22. In the first heat exchanger 22, the refrigerant is dissipated into a medium-temperature and high-pressure liquid refrigerant, which flows through the first expansion valve 24 and becomes a low-temperature and low-pressure liquid refrigerant. Finally, in the second heat exchanger 23, the low-temperature and low-pressure liquid is changed into a low-temperature and low-pressure gaseous state to achieve cooling.

[0036] The cooling medium in the cooling medium flow channel 232 of the second heat exchanger 23 can exchange heat with the refrigerant in the refrigerant flow channel 231 of the second heat exchanger 23 to reduce the temperature of the cooling medium. The cooling medium can flow in the cooling medium circulation loop 45 under the action of the drive pump 30. When the cooling medium flows through the charging device 10, it can carry away the heat of the charging device 10 to achieve refrigeration.

[0037] It should be noted that the cooling device 20 of this application is not integrated into the vehicle. This not only eliminates the risk of leakage caused by aging or loosening of the cooling device 20 pipes, but also improves the space utilization of the vehicle and facilitates the rational arrangement of vehicle space. Moreover, this setting does not consume the vehicle's electrical energy to maintain the operation of the cooling device 20, thus improving the vehicle's driving range.

[0038] Therefore, the cooling device 20 can be arranged outside the vehicle, reducing the risk of leakage caused by loosening of the charging cooling system pipes due to vibration and bumps during vehicle operation, thus improving safety. Moreover, the charging cooling system 100 does not continuously consume the vehicle's electrical energy, which helps to increase the vehicle's driving range. In addition, the cooling device 20 can cool the charging gun 11 and the charging socket assembly 12 at the same time, which can improve the current carrying capacity of the charging socket assembly 12.

[0039] In some embodiments of this utility model, such as Figure 3 As shown, the charging base assembly 12 includes: a charging base 121, a water gun base 122, an inlet pipe 123, and an outlet pipe 124. The charging gun 11 can be electrically connected to the charging base 121. The inlet pipe 123 and the outlet pipe 124 are both connected between the water gun base 122 and the charging base 121. The cooling medium flows into the charging base 121 through the water gun base 122 and the inlet pipe 123 and flows out of the charging base 121 through the outlet pipe 124.

[0040] The charging gun 11 can cooperate with the charging base assembly 12 to make the charging gun 11 and the charging base assembly 12 electrically connected. As some embodiments of this application, the charging gun 11 can be electrically connected to the charging base 121 through a plug.

[0041] The inlet pipe 123 and the outlet pipe 124 are both connected between the water gun holder 122 and the charging holder 121, so that the cooling medium can flow from the water gun holder 122 and the inlet pipe 123 into the charging holder 121, and then flow out of the charging holder 121 and back to the water gun holder 122 from the outlet pipe 124.

[0042] With this configuration, when charging the vehicle, the charging gun 11 can be inserted into the charging socket 121, and the water gun socket 122 can be connected to other components to form a cooling medium circulation loop 45. For example, the water gun can be inserted into the water gun socket 122 to connect the water gun socket 122 to other components to form a cooling medium circulation loop 45. This facilitates operation and improves the convenience of the charging cooling system 100.

[0043] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the cooling medium circulation loop 45 includes: a first cooling medium circulation loop 41 and a second cooling medium circulation loop 42. The charging base assembly 12, the cooling medium flow channel 232, and the drive pump 30 form the first cooling medium circulation loop 41. The charging gun 11, the cooling medium flow channel 232, and the drive pump 30 form the second cooling medium circulation loop 42. The charging base assembly 12 and the charging gun 11 are connected in parallel.

[0044] The charging base assembly 12, the cooling medium flow channel 232, and the drive pump 30 are connected by pipelines to form a first cooling medium circulation loop 41, and the charging gun 11, the cooling medium flow channel 232, and the drive pump 30 are connected by pipelines to form a second cooling medium circulation loop 42. The charging base assembly 12 and the charging gun 11 are connected in parallel.

[0045] This configuration allows the cooling device 20 to independently cool the charging gun 11 and the charging base assembly 12 simultaneously, meeting the different heat dissipation requirements of the charging gun 11 and the charging base assembly 12, thereby improving the cooling efficiency of the charging cooling system 100 and increasing the charging efficiency.

[0046] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the cooling device 20 also includes: a liquid storage tank 35, which forms a first branch 43 with the cooling medium flow channel 232; a charging base assembly 12 forms a first cooling medium circulation loop 41 with the first branch 43; and a charging gun 11 forms a second cooling medium circulation loop 42 with the first branch 43.

[0047] The liquid storage tank 35 is connected to the cooling medium flow channel 232 through a pipeline to form a first branch 43, the charging base assembly 12 is connected to the first branch 43 through a pipeline to form a first cooling medium circulation loop 41, and the charging gun 11 and the first branch 43 form a second cooling medium circulation loop 42.

[0048] This configuration allows the cooling device 20 to independently cool the charging gun 11 and the charging base assembly 12 simultaneously, meeting the different heat dissipation requirements of the charging gun 11 and the charging base assembly 12. Furthermore, by placing the liquid storage tank 35 in the first branch 43, the first branch 43 can have sufficient cooling medium, ensuring that the cooling medium in the first cooling medium circulation loop 41 and the second cooling medium circulation loop 42 is sufficient, thereby improving the reliability of the charging cooling system 100.

[0049] In some embodiments of this utility model, such as Figure 1 As shown, the drive pump 30 is located in the first branch 43. The drive pump 30 can drive the cooling medium from the first branch 43 to the first cooling medium circulation loop 41 and the second cooling medium circulation loop 42 respectively, and from the first cooling medium circulation loop 41 and the second cooling medium circulation loop 42 back to the first branch 43. This arrangement makes the structure of the charging cooling system 100 reasonable. Moreover, the cooling medium can be driven to circulate in the first cooling medium circulation loop 41 and the second cooling medium circulation loop 42 simultaneously by only one drive pump 30, which can reduce the number of parts and reduce the structural complexity of the charging cooling system 100.

[0050] In some embodiments of this utility model, such as Figure 2 As shown, the drive pump 30 includes a first drive pump 31 and a second drive pump 32. The charging base assembly 12, the first drive pump 31, and the first branch 43 form a first cooling medium circulation loop 41, and the charging gun 11, the second drive pump 32, and the first branch 43 form a second cooling medium circulation loop 42. That is, the first drive pump 31 and the second drive pump 32 are connected in parallel.

[0051] This configuration allows for individual control of the power of the first drive pump 31 and the second drive pump 32, facilitating individual and precise control of the cooling power of the first cooling medium circulation loop 41 and the second cooling medium circulation loop 42, which helps to meet the different cooling requirements of the charging gun 11 and the charging base assembly 12.

[0052] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the cooling device 20 also includes a radiator 33, which is located in the first branch 43 and upstream of the cooling medium flow channel 232.

[0053] The radiator 33 is located in the first branch 43 and is located upstream of the cooling medium flow channel 232. That is, the cooling medium flowing through the charging gun 11 can flow to the radiator 33 and then into the cooling medium flow channel 232. In addition, the cooling medium flowing through the charging base assembly 12 can flow to the radiator 33 and then into the cooling medium flow channel 232.

[0054] By including a radiator 33 in the cooling device 20 and placing the radiator 33 in the first branch 43 and upstream of the cooling medium flow channel 232, the cooling medium after heat exchange with the charging gun 11 and the charging base assembly 12 can first flow into the radiator 33 for heat dissipation, and then flow into the cooling medium flow channel 232 to exchange heat with the refrigerant. This allows the cooling medium flowing to the charging gun 11 and the charging base assembly 12 to have a larger cooling capacity, which is beneficial to improving cooling efficiency.

[0055] In some embodiments of this utility model, the cooling medium is configured as cooling water or cooling oil. As some embodiments of this application, the cooling medium flowing through the cooling medium circulation loop 45 can be cooling water, which can be, but is not limited to, an aqueous solution of ethylene glycol or propylene glycol. This configuration allows for the selection of a suitable cooling medium based on actual operating conditions, improving the selectivity of the cooling medium and enhancing the reliability of the charging cooling system 100.

[0056] In some embodiments of this utility model, the charging cooling system 100 further includes: a first temperature sensor and a controller. The first temperature sensor is provided at both the first medium inlet and the first medium outlet of the charging base assembly 12. The first temperature sensor is connected to the controller, and the controller is configured to control the power of the air compressor 21 and / or the first drive pump 31 according to the feedback information of the first temperature sensor.

[0057] In some embodiments of this application, the first temperature sensor and the controller are connected in communication.

As some embodiments of this application, the controller can control the power of the air compressor 21 according to the feedback information of the first temperature sensor. As some embodiments of this application, the controller can control the power of the first drive pump 31 according to the feedback information of the first temperature sensor. As some embodiments of this application, the controller can control the power of the air compressor 21 and the first drive pump 31 according to the feedback information of the first temperature sensor.

[0059] This configuration allows for independent and precise control of the cooling power of the first cooling medium circulation loop 41, thereby accurately adjusting the temperature of the charging dock assembly 12 so that the charging dock assembly 12 remains within a suitable temperature range for an extended period of time.

[0060] In some embodiments of this utility model, the charging cooling system 100 further includes: a second temperature sensor and a controller. The second temperature sensor is provided at both the second medium inlet and the second medium outlet of the charging gun 11. The second temperature sensor is connected to the controller, and the controller is configured to control the power of the air compressor 21 and / or the second drive pump 32 according to the feedback information of the second temperature sensor.

[0063] This configuration allows for independent and precise control of the cooling power of the second cooling medium circulation loop 42, thereby accurately adjusting the temperature of the charging gun 11 so that the charging gun 11 remains within a suitable temperature range for an extended period of time.
