Containerized energy storage power stations have been used even more due to their superior advantages.

Multiple intake cooling fans and multiple exhaust cooling fans are respectively installed on both sides of the housing. Multiple fixed seats are fixedly installed on the bottom inner wall of the housing. A turntable is rotatably installed within each fixed seat. An energy storage mechanism is installed on the top side of the turntable. This invention utilizes a motor to drive a first gear, and a transmission mechanism, in conjunction with two sets of driven mechanisms, enables the reciprocating intermittent rotation of multiple energy storage mounting frames and energy storage power station equipment within the housing. This facilitates the airflow through the gaps within the housing, providing comprehensive air cooling for the intermittently rotating energy storage mounting frames and energy storage power station equipment.

[0004] Most existing energy storage terminals use air cooling for heat dissipation. However, air cooling has limited effectiveness when dealing with high-energy-density, high-power-output energy storage modules. High temperatures accelerate the aging and damage of these modules, shortening their lifespan and leading to performance degradation. Therefore, it is necessary to improve this structure to overcome these shortcomings. Utility Model Content

The cooling host is connected to the cooling pipes and is used to pump a cooling medium into the cooling pipes. After absorbing heat, the cooling medium flows back to the cooling host through the cooling pipes.

[0008] A further feature of this invention is that one end of the air inlet is located on the inner wall of the housing, and the other end of the air inlet is located on the outer wall of the housing.

[0021] 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.

[0022] like Figure 1 As shown, the present invention proposes a liquid-cooled container energy storage terminal, including a housing 1. The housing 1 has an internal cavity. An air inlet 2 and an air outlet 3 are provided on the housing 1. One end of the air inlet 2 is connected to the cavity, and the other end of the air inlet 2 is connected to the outside of the housing 1. One end of the air outlet 3 is connected to the cavity, and the other end of the air outlet 3 is connected to the outside of the housing 1. External air can flow into the housing 1 through the air inlet 2, and the air inside the housing 1 can flow out through the air outlet 3, thereby realizing the air circulation inside the housing 1.

[0023] A cooling assembly is installed within the cavity, comprising a cooling unit 4 and cooling pipes 5. The air inlet of the cooling unit 4 faces the air inlet 2, and the air outlet faces the air outlet 3. The cooling unit 4 is connected to the cooling pipes 5 and pumps the cooling medium into the cooling pipes 5. After absorbing heat, the cooling medium flows back into the cooling unit 4 through the cooling pipes 5. The cooling unit 4 integrates a cooling pump (omitted in the figure) and a condenser (omitted in the figure). The cooling pump provides the driving force to pump the cooling medium out of the cooling unit 4 and allow it to flow along the cooling pipes 5. During the flow, the cooling medium absorbs heat from the surrounding environment and gradually heats up. The heated cooling medium flows back into the cooling unit 4, where it is cooled by the condenser and then pumped out again for the next cycle. The condenser cools the returning cooling medium, transferring the heat from the returning cooling medium to the external environment.

[0024] like Figure 2 As shown, a filter grille 6 is installed on the air intake end of the cooling host 4. The filter grille 6 is used to filter out impurities in the air and prevent impurities from entering the cooling host 4.

[0025] like Figure 2 As shown, a guide fan 7 is installed on the air outlet of the cooling host 4. The air inlet of the guide fan 7 is connected to the inside of the cooling host 4. The air outlet of the cooling host 4 is set towards the air outlet 3. The guide fan 7 is used to guide the air inside the cooling host 4 to the outside through the air outlet 3. The air inlet 2 of the guide fan 7 is set towards the condenser. When in use, the guide fan 7 is started to generate airflow. The air flows through the condenser, takes away the heat on the condenser and discharges it to the outside.

[0026] like Figure 2 As shown, a medium inlet 8 is provided at one end of the cooling pipe 5, and a medium outlet 9 is provided at the other end of the cooling pipe 5. The cooling pipe 5 is connected to the cooling host 4 through the medium inlet 8 and the medium outlet 9. The cooling medium in the cooling host 4 enters the cooling pipe 5 through the medium inlet 8, and the cooling medium in the cooling pipe 5 enters the cooling host 4 through the medium outlet 9. Preferably, a first on / off valve 10 is installed on the medium inlet 8, and a second on / off valve 11 is installed on the medium outlet 9. When cooling is required, the first on / off valve 10 is opened, allowing the cooling medium to flow in; when cooling is not required, the first on / off valve 10 is closed, cutting off the supply of cooling medium, and then the second on / off valve 11 is opened, and the cooling medium is pumped back into the cooling host 4 by the cooling pump.

[0027] Multiple overflow pipes 12 are installed on the cooling pipe 5. The overflow pipes 12 are connected to the cooling pipe 5. An on / off valve 13 is installed on the overflow pipe 12. When in use, the energy storage module of the energy storage terminal is placed in the receiving cavity. The cooling port on the energy storage module (omitted in the figure) is connected to the cooling channel through the overflow pipe 12. The cooling medium is introduced into the cooling port to cool the energy storage module.

[0028] like Figure 3 As shown, one end of the air inlet 2 is located on the inner wall of the housing 1, and the other end of the air inlet 2 is located on the outer wall of the housing 1. External air flows into the receiving cavity through the air inlet 2. An air intake grille 14 is installed inside the air inlet 2. The air intake grille 14 is used to filter out impurities contained in the air. Preferably, the air intake grille 14 is detachably installed inside the air inlet 2.

[0029] like Figure 3 As shown, one end of the air outlet 3 is located on the inner side wall of the housing 1, and the other end of the air outlet 3 is located on the outer side wall of the housing 1. The air in the receiving cavity flows to the outside of the housing 1 through the air outlet 3. An air outlet grille 15 is installed inside the air outlet 3. The air outlet grille 15 is used to filter out impurities contained in the air. Preferably, the air outlet grille 15 is detachably installed inside the air outlet 3.

[0030] The working principle of this utility model is as follows: The liquid-cooled energy storage terminal adopts a circulating cooling medium, which has higher heat transfer efficiency and cooling effect compared with the traditional air-cooled system. The cooling medium can more effectively absorb and remove the heat generated by the energy storage module, ensuring that the energy storage module operates within a safe and stable operating temperature range and improving the service life of the energy storage module.

[0031] In summary, liquid-cooled energy storage terminals solve problems such as heat dissipation of energy storage modules, improve energy utilization efficiency, and extend the lifespan of energy storage modules, achieving efficient heat dissipation, energy saving and environmental protection, and improved system stability.
