Description

Technical Field

[0001] This utility model relates to the field of charging pile structure, and in particular to a modular fast charging pile structure based on liquid cooling. Background Technology

[0002] Modular fast charging piles are charging devices where each functional unit is designed as an independent module. They offer high flexibility, scalability, and reliability. The power input module converts AC power from the grid to DC power, and the charging module precisely controls the charging process according to the electric vehicle's needs. The control module monitors the charging status in real time and dynamically adjusts charging parameters based on feedback from the battery management system, ensuring a safe and efficient charging process. During charging, the display and operation module provides users with intuitive information and a convenient user interface. The safety protection module constantly monitors the circuit status and immediately cuts off the power in case of any abnormality, ensuring the safety of equipment and personnel. The communication module is responsible for data interaction with external systems, enabling remote monitoring and management.

[0003] Most existing charging piles use air cooling for heat dissipation. However, during fast charging, the power modules inside the charging pile generate a lot of heat. Air cooling has relatively limited heat dissipation capabilities and cannot dissipate the heat quickly and effectively. Especially in high-power charging scenarios, this may cause the internal temperature of the charging pile to become too high, affecting the performance and lifespan of the equipment. Furthermore, when the internal temperature of the charging pile becomes too high, the charging module may automatically reduce the charging power to protect the equipment, thereby extending the charging time and reducing charging efficiency.

[0004] Therefore, most of the existing charging pile structures use air cooling for heat dissipation. However, due to their relatively limited heat dissipation capacity, it is difficult to dissipate heat quickly and effectively, which affects the performance and lifespan of the equipment. Furthermore, if the temperature is too high for a long time, the charging module will automatically reduce the charging power. A modular fast charging pile structure based on liquid cooling can be designed to improve the charging efficiency of the charging pile. Utility Model Content

[0005] To overcome the problem that most existing charging pile structures use air cooling, which has relatively limited heat dissipation capacity, making it difficult to quickly and effectively dissipate heat, affecting the performance and lifespan of the equipment, and causing the charging module to automatically reduce charging power when the temperature is too high for a long time.

[0006] The technical solution of this utility model is as follows: a modular fast charging pile structure based on liquid cooling heat dissipation, including a shell, a placement box, and a liquid supply tank; a placement box for liquid cooling heat dissipation of the shell is provided on one side of the shell, and a liquid supply tank for supplying coolant is provided on the other side of the shell. A first cover plate is provided on one side of the placement box, and a first loop-shaped sealing strip is installed at the edge of one side of the first cover plate. The first loop-shaped sealing strip drives the first cover plate to fit and connect with it along the inner wall of the placement box. A connecting water pipe is provided between the first cover plate and the placement box. A water inlet pipe is installed at one end of the connecting water pipe, and a water outlet pipe is installed at the end of the connecting water pipe away from the water inlet pipe. A circulation pump is provided outside the water inlet pipe, and a cooler is provided at the bottom of the inner side of the liquid supply tank.

[0007] Furthermore, a base plate is installed at the lower end of the housing, a cable is installed on one side of the housing, and a charging gun is installed at the end of the cable away from the housing.

[0008] Furthermore, a U-shaped snap-fit ​​groove is provided on one edge of the housing, and a rectangular sealing cover is provided on one side of the housing. A U-shaped snap-fit ​​plate is installed on one edge of the rectangular sealing cover, and the U-shaped snap-fit ​​plate drives the rectangular sealing cover to be positioned and snapped into the housing along the U-shaped snap-fit ​​groove.

[0009] Furthermore, a charging module is located on the upper inner side of the housing, and multiple power modules are arrayed below the charging module.

[0010] Furthermore, a fixing ring sleeve that is fixedly connected to the first cover plate is fitted around the outside of the connecting water pipe.

[0011] Furthermore, both the outlet and inlet pipes are fitted with mounting rings, and multiple sets of plug-in posts are installed around the edge of the mounting rings near the liquid supply tank.

[0012] Furthermore, a second cover plate is provided above the liquid supply tank, with a water inlet pipe installed in the middle of the second cover plate, and a second loop-shaped sealing strip installed at the lower edge of the second cover plate. The second loop-shaped sealing strip drives the second cover plate to fit and connect with the inner wall of the liquid supply tank.

[0013] Furthermore, the liquid supply tank has two sets of connecting holes on the side near the shell, and multiple sets of insertion holes are arranged around the liquid supply tank outside the connecting holes. The insertion post drives the mounting ring to be positioned and connected to the liquid supply tank through the insertion holes.

[0014] The beneficial effects of this invention are as follows: The coolant, within a carefully designed placement box, undergoes efficient liquid circulation via connecting pipes, continuously carrying away the large amount of heat generated during charging. This heat-carrying coolant then flows into the supply tank, where a cooler, with its excellent heat exchange performance, rapidly lowers the coolant's temperature, restoring its cooling capacity. This cycle repeats, forming a highly efficient heat dissipation loop. Compared to traditional air cooling, this innovative liquid cooling method significantly improves heat dissipation efficiency. This not only helps control the operating temperature of the charging pile's internal electronic components within a reasonable and safe range but also effectively avoids problems such as component performance degradation, shortened lifespan, or even damage caused by overheating. Therefore, this efficient heat dissipation system ensures that the charging pile maintains stable and efficient performance even under long-term, high-load operation. Even under high-power output, the charging pile can maintain good operating conditions thanks to this superior heat dissipation performance, ensuring the safety and stability of the charging process. This not only meets users' urgent need for fast charging but also further improves charging efficiency, providing strong support for the popularization and development of electric vehicles.

[0022] Example 1:

[0023] like Figures 1-5 As shown, a modular fast charging pile structure based on liquid cooling includes a housing 1, a placement box 2, and a liquid supply tank 3. The inner side of the housing 1 is provided with a placement box 2 for liquid cooling of the housing 1, and the outer side of the housing 1 is provided with a liquid supply tank 3 for supplying coolant. The placement box 2 is provided with a first cover plate 201, and a first loop-shaped sealing strip 202 is installed at the edge of the first cover plate 201. The first loop-shaped sealing strip 202 drives the first cover plate 201 to fit and connect with it along the inner wall of the placement box 2. A connecting water pipe 204 is provided between the first cover plate 201 and the placement box 2. A water inlet pipe 203 is installed at one end of the connecting water pipe 204, and a water outlet pipe 205 is installed at the end of the connecting water pipe 204 away from the water inlet pipe 203. A circulation pump 209 is provided outside the water inlet pipe 203. A cooler 304 is provided at the bottom of the inner side of the liquid supply tank 3.

[0024] A base plate 101 is installed at the lower end of the housing 1, and a cable 102 is installed on one side of the housing 1. A charging gun 103 is installed at the end of the cable 102 away from the housing 1. The charging gun 103 is picked up to start the charging operation. The housing 1 is then started. Then the charging module 107 is responsible for converting the input electrical energy into DC power suitable for charging electric vehicles.

[0025] A U-shaped snap-fit ​​groove 104 is provided on one edge of the housing 1, and a rectangular sealing cover 105 is provided on one side of the housing 1. A U-shaped snap-fit ​​plate 106 is installed on one edge of the rectangular sealing cover 105. The U-shaped snap-fit ​​plate 106 drives the rectangular sealing cover 105 to be positioned and snapped with the housing 1 along the U-shaped snap-fit ​​groove 104.

[0026] A charging module 107 is provided on the upper inner side of the housing 1, and multiple power modules 108 are arranged in an array below the charging module 107. The power modules 108 are connected in parallel to achieve higher charging power.

[0027] A fixing ring 206 is fitted on the outside of the connecting water pipe 204 and fixedly connected to the first cover plate 201. The fixing ring 206 drives the connecting water pipe 204 to be fixedly connected to the first cover plate 201, thereby improving the stability of the coolant circulation.

[0028] Both the outlet pipe 205 and the inlet pipe 203 are fitted with mounting rings 207. Multiple sets of plug posts 208 are installed around the edge of the mounting rings 207 near the liquid supply tank 3.

[0029] A second cover plate 301 is provided above the liquid supply tank 3. A water inlet pipe 302 is installed in the middle of the second cover plate 301. A second loop-shaped sealing strip 303 is installed at the lower edge of the second cover plate 301. The second loop-shaped sealing strip 303 drives the second cover plate 301 to fit and connect with it along the inner wall of the liquid supply tank 3.

[0030] Two sets of connection holes 305 are horizontally opened on the side of the liquid supply tank 3 near the shell 1. Multiple sets of insertion holes 306 are opened around the liquid supply tank 3 around the connection holes 305. The insertion post 208 drives the mounting ring 207 to be positioned and connected to the liquid supply tank 3 through the insertion holes 306.

[0031] Pick up the charging gun 103 to start the charging operation, start the housing 1, and then the charging module 107 is responsible for converting the input electrical energy into DC power suitable for charging electric vehicles. During this process, the power module 108 adopts multiple parallel connection to achieve higher charging power. Then, the coolant is poured into the supply tank 3 through the water inlet pipe 302. During the charging process, driven by the circulation pump 209, the coolant enters the water inlet pipe 203 from the supply tank 3, reaches the connecting water pipe 204, and then returns to the supply tank 3 through the water outlet pipe 205 to complete the liquid cooling cycle. Then, through the action of the cooler 304, the coolant that returns to the supply tank 3 is cooled again to achieve liquid cooling heat dissipation.

[0032] After a period of use, disassemble the liquid supply tank 3 and the rectangular sealing cover 105, remove the placement box 2, and then open the first cover plate 201 to inspect the connecting water pipe 204. After the inspection is completed, the first loop-shaped sealing strip 202 drives the first cover plate 201 to fit and connect with the inner wall of the placement box 2. Then, place the placement box 2 back into the housing 1. Then, the loop-shaped snap-fit ​​plate 106 drives the rectangular sealing cover 105 to be positioned and snapped into the housing 1 along the loop-shaped snap-fit ​​groove 104. Return the liquid supply tank 3 to its original position. At the same time, the plug-in post 208 drives the mounting ring 207 to be positioned and connected to the liquid supply tank 3 through the plug-in hole 306, so that the water inlet pipe 203 and the water outlet pipe 205 pass through the connection hole 305 and go deep into the liquid supply tank 3. Finally, the second cover plate 301 can be opened to clean the inside of the liquid supply tank 3 or to inspect the cooler 304. After the treatment is completed, the second circular sealing strip 303 drives the second cover plate 301 to fit and connect with it along the inner wall of the liquid supply tank 3.
