[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with the illustrations and specific embodiments.

[0025] like Figs. 1 to 4 As shown, the liquid-cooled energy storage terminal proposed in this utility model includes a base 1, which provides support and installation space. A housing 2 is mounted on the base 1, the housing 2 has an internal accommodating space, and a door is mounted on the housing 2. It also includes...

[0026] An energy storage unit is disposed inside the outer casing 2. The energy storage unit includes multiple cooling shells 3 and a battery pack 4. The battery pack 4 is disposed inside the cooling shells 3 and is used to store electrical energy. The cooling shells 3 have a space to accommodate a cooling medium. The cooling medium flows through the cooling shells 3 and carries away the heat from the battery pack 4.

[0027] An air-cooled unit is installed inside the outer casing 2. This unit expels hot air from inside the casing 2 to the outside via convection, effectively reducing the temperature inside the casing 2. Adding an air-cooled unit to the liquid-cooled energy storage terminal, working in conjunction with the liquid-cooled unit, improves heat dissipation efficiency.

[0028] The liquid cooling unit is located inside the outer casing 2 and is connected to the cooling housing 3. The liquid cooling unit is used to cool the battery pack 4 by introducing a cooling medium into the cooling housing 3. The liquid cooling unit includes a liquid chiller 5 and a liquid cooling pipe 6. The liquid chiller 5 integrates a circulation pump. The liquid cooling pipe 6 has an inlet 7, an outlet 8, and a cooling port 9. The cooling pipe is connected to the output end of the liquid chiller 5 through the inlet 7, the input end of the liquid chiller 5 through the outlet 8, and the cooling port 9. The liquid cooling unit directly introduces the cooling medium into the cooling housing 3 to cool the battery pack 4 through liquid circulation. For high-power battery packs 4, the liquid cooling unit can dissipate heat more effectively.

[0029] An air inlet 10 is installed on the door body. One end of the air inlet 10 is located on the outer wall of the door body, and the other end of the air inlet 10 is connected to the inside of the outer shell 2, allowing cold air from outside to enter the shell through the air inlet 10. An air outlet 11 is installed on the shell body. One end of the air outlet 11 is connected to the inside of the outer shell 2, and the other end of the air outlet 11 is located on the outer wall of the outer shell 2, allowing hot air from inside the outer shell 2 to be discharged outward through the air outlet 11.

[0030] Multiple sets of fasteners 12 are installed on the inner wall of the outer casing 2. The fasteners 12 have accommodating spaces. The cooling outer casing 2 is set on the fasteners 12. The fasteners 12 are used to support and fix the cooling outer casing 2. When replacement or maintenance is required, the cooling outer casing 2 can be directly removed from the fasteners 12.

[0031] The cooling housing 2 has a connection port that matches the cooling inlet 9. The cooling housing 2 is connected to the cooling pipe through the connection port to form a complete coolant circulation loop. Under the action of the circulation pump, the coolant enters the cooling housing 2 through the cooling pipe, absorbs the heat generated by the battery pack 4, and then flows back to the liquid cooler 5 to realize the transfer and dissipation of heat.

[0032] The air-cooled unit includes a fan 13. The air inlet end of the fan 13 is set towards the air inlet 10, and the air outlet end of the fan 13 is set towards the air outlet 11. The fan 13 is used to realize the air circulation inside and outside the housing 2, continuously introducing external cold air into the housing 2 and expelling the hot air that has absorbed heat from the housing 2, thereby reducing the temperature inside the housing 2.

[0033] An air channel 14 is provided between any two cooling housings 3. The air channel 14 increases the heat dissipation area inside the cooling housing 3, allowing heat to be dissipated to the external environment more quickly. This, together with the air-cooling unit and the liquid-cooling unit, further improves the heat dissipation efficiency.

[0034] The operating principle of this utility model is as follows: By combining liquid cooling and air cooling, the operating temperature of the battery pack 4 is effectively reduced, extending its service life and maintaining stable performance output within the temperature range. This reduces the risk of failure caused by overheating of the battery pack 4 and improves the stability of the entire energy storage system. In summary, the liquid-cooled energy storage terminal, through the integration of liquid cooling and air cooling, demonstrates advantages and functions such as high-efficiency heat dissipation, compact structure, ease of maintenance, and strong adaptability. It provides strong protection for the safe and efficient operation of energy storage systems and also provides strong support for the application and development of new energy sources.
