Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to a liquid-cooled car charging pile. Background Technology

[0002] Currently, electric vehicles mostly use charging piles for charging. In order to reduce costs and size, charging piles have evolved from the traditional single-pile single-gun to multi-gun (one pile with two guns, one pile with four guns, or even one pile with six guns). The number of integrated power modules is greater, while the volume of the pile body relative to each power module is decreasing, which makes the internal heat generation of the charging pile more serious.

[0003] Among them, announcement number CN218218136U discloses a liquid-cooled charging pile, involving the field of new energy vehicles. It includes a charging pile housing, within which a heat-absorbing module is installed. The heat-absorbing module includes a housing, and within the housing, multiple sets of heat-absorbing chambers are arranged vertically at intervals. A charging module is installed between each pair of adjacent heat-absorbing chambers. Coils are installed within the heat-absorbing chambers, which are filled with coolant, and the coils are immersed in the coolant. The coils within the multiple sets of heat-absorbing chambers are connected in series, forming a coolant inlet and an outlet for the heat-absorbing module. Below the heat-absorbing module are a coolant tank, a thermostat, and a water pump. The coolant tank is connected to the heat-absorbing module, the heat-absorbing module is connected to the thermostat, the thermostat is connected to the water pump, and the water pump is connected to the coolant tank. This design achieves high-efficiency heat dissipation within the charging pile, improves the safety of the charging pile, reduces noise, and minimizes its own energy loss.

[0004] During prolonged use, the charging module is prone to damage, requiring regular maintenance to ensure the safety of the charging station. However, this device involves alternating installation and fixing of multiple charging modules and multiple heat absorption modules, necessitating disassembly for maintenance. This process is cumbersome and inefficient.

[0005] Therefore, it is necessary to invent a liquid-cooled car charging station to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a liquid-cooled car charging station to solve the problems of inconvenience in inspecting and repairing the charging module, the cumbersome inspection process, and the low efficiency of inspection.

Optionally, the surface of the cooling box is fixedly connected with two sets of quick-release connectors, the liquid inlet pipe is fixedly connected to the right quick-release connector, and the liquid outlet pipe is fixedly connected to the left quick-release connector.

[0017] By adopting the above technical solution, the quick-release connector facilitates the rapid assembly and disassembly of the inlet and outlet pipes.

[0020] Optionally, multiple cooling fans are fixedly installed on the inner surface of the second heat sink.

[0021] By adopting the above technical solutions, the cooling fan further improves the heat dissipation effect.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model uses the positioning block and positioning groove to drive the support plate to slide back and forth on the surface of the support guide rail. During maintenance, the charging module and cooling box can be pulled out to the outside of the charging pile body, which facilitates the maintenance of the charging module and improves the convenience of maintenance. 2.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 4 The liquid-cooled car charging pile shown includes a charging pile body 1. A control panel 11 is fixedly connected to the front surface of the charging pile body 1. Charging interfaces 12 are provided on both the left and right sides of the charging pile body 1. A first heat dissipation plate 13 is fixedly connected to the right side of the charging pile body 1, and a second heat dissipation plate 14 is fixedly connected to the left side of the charging pile body 1. Multiple cooling fans 15 are fixedly installed on the inner surface of the second heat dissipation plate 14. A vertical mounting plate 16 is fixedly connected inside the charging pile body 1. A mounting assembly is provided on the rear side of the mounting plate 16. The mounting assembly includes a support guide rail 2, a support plate 21, a charging module 22, a cooling box 23, a positioning groove 25, and a positioning block 26.

[0027] During the charging process, multiple charging modules 22 provide power, connecting the charging cable to the charging interface 12. The other end of the charging cable is connected to the charging port of the electric vehicle, thus charging the vehicle. During the charging process, information such as the charging level and charging amount can be observed on the surface of the control panel 11.

[0028] During operation, the cooling fan 15, together with the first heat sink 13 and the second heat sink 14, increases the airflow speed and works with the cooling box 23 to cool the charging module 22, thereby achieving rapid heat dissipation of the charging module 22 and improving the safety of the charging pile body 1.

[0029] See Figures 2 to 4 Multiple sets of support rails 2 are fixedly connected to the rear surface of the mounting plate 16. The support plate 21 is mounted on the upper side of the support rails 2. The charging module 22 and the cooling box 23 are both fixedly mounted on the upper side of the support plate 21. The cooling box 23 is close to the rear surface of the charging module 22. Two sets of positioning grooves 25 are provided on both the left and right sides of the support rails 2. Two sets of positioning blocks 26 are fixedly connected to both the left and right sides of the lower surface of the support plate 21. The positioning blocks 26 are slidably connected to the positioning grooves 25.

[0030] In addition, during the installation of the charging module 22 and the cooling box 23, the charging module 22 is placed directly on the upper side of the support plate 21 and pushed to the front. Then the cooling box 23 is placed on the rear side of the charging module 22 and locked between the cooling box 23 and the rear vertical plate of the support plate 21. At this time, the charging module 22 and the cooling box 23 are tightly fixed on the upper side of the support plate 21.

[0031] Meanwhile, the positioning block 26 slides back and forth inside the positioning groove 25, thereby driving the support plate 21 to slide back and forth on the surface of the support guide rail 2. When the charging module 22 needs to be inspected, the inspection plate on the rear side of the charging pile body 1 can be opened directly, and the support plate 21 can be pulled to the rear side. The charging module 22 can be pulled out to the outside of the charging pile body 1. At this time, there is enough working space to inspect the inside of the charging module 22 without disassembling the charging module 22, which effectively improves the convenience and efficiency of inspection.

[0032] When it is necessary to disassemble the charging module 22 under special circumstances, simply pull the cooling box 23 upwards, and the charging module 22 can be removed directly, improving the convenience of disassembly and assembly.

[0033] See Figure 2 and Figure 3 A cooling box 3 is fixedly connected to the bottom of the charging pile body 1. A circulation pump 31 is fixedly installed on the right side of the cooling box 3. An infusion pipe 32 is fixedly connected to the output end of the circulation pump 31. Multiple sets of inlet pipes 33 are fixedly connected to the surface of the infusion pipe 32. A return pipe 34 is fixedly connected to the left side of the cooling box 3. Multiple sets of outlet pipes 35 are fixedly connected to the surface of the return pipe 34. Two sets of quick-release connectors 24 are fixedly connected to the surface of the cooling box 23. The inlet pipe 33 is fixedly connected to the right quick-release connector 24, and the outlet pipe 35 is fixedly connected to the left quick-release connector 24.

[0034] Specifically, during the cooling process of the charging module 22, the circulation pump 31 draws the coolant from inside the cooling box 3 into the infusion pipe 32. The infusion pipe 32 injects the coolant into the circulation pipe inside the cooling box 23 through multiple sets of inlet pipes 33. At this time, the coolant works with the cooling box 23 to cool the charging module 22. After passing through the circulation pipe inside the cooling box 23, the coolant flows into the outlet pipe 35 and then flows back into the cooling box 3 through the return pipe 34 for cooling.

[0035] The working principle of this utility model is as follows: the positioning block 26 and the positioning groove 25 cooperate to drive the support plate 21 to slide back and forth on the surface of the support guide rail 2. During maintenance, the charging module 22 and the cooling box 23 can be directly pulled out to the outside of the charging pile body 1, which facilitates the maintenance of the charging module 22 and improves the convenience of maintenance. At the same time, by locking the charging module 22 and the cooling box 23 between the front and rear vertical plates of the support plate 21, when it is necessary to disassemble the charging module 22, the cooling box 23 can be pulled upwards, and then the charging module 22 can be removed, which improves the convenience of disassembly and further improves the maintenance efficiency.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
