[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0023] Combined Figure 1 and Figure 2 , a liquid cooling structure for an energy storage device, includes a box body 1. Inside the box body 1, a liquid cooling component 2 for dissipating heat of the energy storage device is provided. On the upper surface of the box body 1, an energy storage housing 3 is provided, and a battery module is arranged inside the energy storage housing 3.

[0024] The following will further describe the present utility model in conjunction with embodiments.

[0025] Embodiment 1:

[0026] Please refer to Figures 1 - 5 , the liquid cooling component 2 includes a box body 21 fitted and connected to one side of the box body 1, a movable plate 22 hinged to one side of the box body 21, and a liquid storage tank 23 and a circulation pump 24 arranged inside the box body 21. One end of the liquid storage tank 23 is provided with a liquid cooling pipe 25. The other end of the liquid storage tank 23 is communicated with the circulation pump 24. One end of the circulation pump 24 is provided with a filter pipe 26. One end of the filter pipe 26 is communicated with the liquid cooling pipe 25. A filter core is inserted inside the filter pipe 26. The coolant first flows out from the liquid storage tank 23 into the filter pipe 26. Inside the filter pipe 26, it is then filtered and purified by the filter core to remove impurities, particles and pollutants therein, which can effectively protect each component of the liquid cooling component 2 and avoid impurities and sediments from affecting the normal operation of the system. The filtered coolant is then pumped into the liquid cooling pipe 25 by the circulation pump 24 for circulating cooling. At the same time, since the filter core is inserted into the filter pipe 26, it is convenient to replace the filter core regularly. In addition, since the liquid storage tank 23, the circulation pump 24 and the filter pipe 26 are all arranged inside the box body 21, they can be repaired and inspected by opening the movable plate 22 to prevent problems from occurring at the connection part, so that the liquid cooling component 2 is more convenient for maintenance and installation.

[0027] The upper surface of the filter pipe 26 is threadedly connected with a cover plate 261, and the inside of the filter pipe 26 can be cleaned by opening the cover plate 261.

[0028] A dust-proof net 4 is provided at the connection between the box body 21 and the box 1, which can not only prevent the equipment in the box body 21 from falling into the box 1, but also prevent dust from the outside from entering the box 1 when the movable plate 22 is opened for maintenance.

[0029] The liquid cooling pipe 25 is arranged as a serpentine pipeline, which can increase the heat dissipation area.

[0030] A heat-conducting gasket 5 is provided on the inner wall of the box 1. The heat-conducting gasket 5 is located between the liquid cooling pipe 25 and the battery module, filling the tiny gap, reducing the thermal resistance and improving the heat conduction efficiency.

[0031] A fan 6 is provided on the inner wall of the box 1 to assist in heat dissipation and accelerate the heat dissipation process of the coolant.

[0032] A temperature sensor 7 is provided inside the box 1. The temperature sensor 7 is signal-connected to the circulation pump 24. A control panel 8 is provided on the outer surface of the box 1. The control panel 8 is signal-connected to the temperature sensor 7. The temperature sensor can monitor the temperature change inside the equipment. Once the temperature exceeds the set threshold, the sensor will send a signal to the control system, and the control system will correspondingly adjust the working state of the circulation pump 24.

[0033] Specifically, connect the box body 1 with the energy storage housing 3 and ensure that the position of the box body 1 corresponds to the battery module for better heat dissipation. Since a temperature sensor 7 is provided inside the box body 1 and the control panel 8 is signal-connected to the temperature sensor 7, the temperature inside the box body 1 can be detected through the control panel 8, and the operation of the liquid cooling component 2 can be controlled. In addition, a heat-conducting gasket 5 is provided on the inner wall of the box body 1, and the heat-conducting gasket 5 is located between the liquid cooling pipe 25 and the battery module, so as to fill the tiny gap, reduce the thermal resistance, and improve the heat conduction efficiency. When heat dissipation is required, the coolant first flows out from the liquid storage tank 23 into the filtering pipeline 26. Inside the filtering pipeline 26, it is then filtered and purified by the filter element to remove impurities, particles and pollutants therein, which can effectively protect the various components of the liquid cooling component 2 and prevent impurities and sediments from affecting the normal operation of the system. The filtered coolant is then pumped into the liquid cooling pipe 25 by the circulation pump 24 for circulating cooling. And the liquid cooling pipe 25 is arranged as a serpentine pipeline, which can increase the heat dissipation area. At the same time, the filter element is inserted into the filtering pipeline 26, so it is convenient to replace the filter element regularly. In addition, since the liquid storage tank 23, the circulation pump 24 and the filtering pipeline 26 are all arranged in the box body 21, they can be repaired and inspected by opening the movable plate 22 to prevent problems from occurring in the connection part, so that the liquid cooling component 2 is more convenient for maintenance and installation. Also, because a cover plate 261 is threadedly connected to the upper surface of the filtering pipeline 26, the inside of the filtering pipeline 26 can also be cleaned by opening the cover plate 261. In addition, a dust-proof net 4 is provided at the connection between the box body 21 and the box body 1, which can not only prevent the equipment in the box body 21 from falling into the box body 1, but also prevent external dust from entering the box body 1 when the movable plate 22 is opened for maintenance.
