[0002] With the booming electric vehicle market, the demand for efficient and fast charging facilities is surging. The XGCM100040, a 40kW DC charging module, has emerged as a response to this demand. Leveraging its SiC device design, it demonstrates numerous outstanding performance advantages, helping elevate the electric vehicle charging industry to new heights. Its wide constant power and voltage range adapts to the charging voltage requirements of various EV battery models, ensuring stable and efficient power transmission and rapid charging in diverse charging scenarios. Its high power factor effectively reduces reactive power losses in the grid, improving power efficiency and aligning with the broader trend of energy conservation and environmental protection. Its high power density makes the module compact, facilitating integration into charging piles in confined spaces, saving space. Furthermore, its low electromagnetic radiation and interference ensure the normal operation of peripheral electronic equipment and communication systems, ensuring a stable and reliable charging environment. Furthermore, the module is designed to operate within a temperature range of -40°C to +75°C. Given that electronic device performance is affected by temperature in actual operating conditions, especially in high-temperature environments, output derating is applied above 50°C to ensure stable operation and lifespan, preventing overheating and damage.

[0030] Furthermore, the fixing mechanism also includes a trapezoidal slider 6, a sliding table 7, a connecting shaft 8, and a connecting seat 19. The connecting shaft 8 is in a "Z" shape, and cylindrical blocks are installed at both ends and the middle of the connecting shaft 8.

[0031] Furthermore, a through hole is provided on the side of the long side of the heat dissipation housing 1 , a push rod 2 is slidably connected in the through hole of the heat dissipation housing 1 , and two through holes are symmetrically provided on the other long side of the heat dissipation housing 1 .

[0032] Furthermore, the cooling device includes a condenser 11, a condensing tube 12, a delivery pump 13, and a heat absorber 14. The heat absorber 14 is fixedly installed on the bottom surface of the sliding table 7. The two ends of the heat absorber 14 are connected to the condensing tube 12.

The charging module 5 is fixed on the sliding table 7 so that the heat absorber 14 absorbs the heat. The heat transferred by the charging module 5 is transferred to the condenser 11 through the condensate in the condenser tube 12 on one side. After being cooled by the condenser 11, the condensate is transferred to the heat absorber 14 through the condenser tube 12 on the other side for circulation cooling. This cycle effectively and timely absorbs the heat generated by the charging module 5. This design not only improves the overall thermal management performance, but also ensures that the equipment can maintain a stable operating temperature under high load or long-term working conditions, thereby preventing performance degradation and failure due to overheating. The compact layout of the cooling device also makes the equipment more space-saving and easy to integrate into various application scenarios.

[0033] Working principle: Place the charging module 5 in the rectangular groove of the sliding table 7, push the push rod 2, the slider 16 squeezes the wedge block 18 and the spring 20 forward, the wedge block 18 moves to both sides, and the bottom connecting shaft 8 connected to the wedge block 18 also moves to both sides. The middle part of the connecting shaft 8 is rotated and connected to the connecting seat 19, thereby driving the top connecting shaft 8 to move inward. At the same time, the trapezoidal slider 6 connected to the upper connecting shaft 8 slides in the trapezoidal groove of the sliding table 7 to clamp the charging module 5. The charging module 5 is in operation, and the cooling fan 4 is started. The cooling fan 4 blows air. The heat conducting plate 9 is rotated according to the position of the charging module 5 so that the wind energy blown out by the cooling fan 4 is directed to the charging module 5, and the delivery pump 13 is started. After the heat absorber 14 absorbs the heat transferred by the charging module 5, the heat is transferred to the condenser 11 through the condensate in the condenser tube 12 on one side. After the cooling treatment of the condenser 11, the condensate is transferred to the heat absorber 14 through the condenser tube 12 on the other side for circulating cooling. After the charging module 5 is removed, the spring 20 loses pressure, rebounds and drives the wedge block 18 forward, and the fixing mechanism returns to its original state.
