[0030] As mentioned in the background section, in existing technologies, the piping of liquid-cooled containerized energy storage systems needs to pass through the wall from one compartment to another. That is, the liquid cooling piping needs to pass through the wall from an indoor compartment to an outdoor compartment, or vice versa. A common method is to directly pass the liquid cooling piping through the wall and seal the gaps with fire-resistant putty. This results in poor waterproofing, unsightly sealing, and inconvenient operation. To address this, this application proposes an energy storage box comprising a battery compartment and a sealing structure. The sealing structure is integrally formed and installed on the side wall of the battery compartment, solving the problems of poor waterproofing, unsightly sealing, and inconvenient operation of the through-wall liquid cooling piping in existing liquid-cooled containerized energy storage systems. The energy storage box of this application will be described in detail below with reference to the accompanying drawings.

[0031] See Figures 1 to 3 As shown, according to an embodiment of the present invention, an energy storage box is provided, which includes a battery compartment 10 and a sealing structure 20.

[0032] Specifically, the battery compartment 10 includes an inlet pipe 11 and an outlet pipe 12. The battery compartment 10 includes a first side wall 13, on which an avoidance through hole (not shown in the figure) is provided. The sealing structure 20 includes a mounting plate 21, a first connecting pipe 22, a second connecting pipe 23, and a sealing element 24. The mounting plate 21 is disposed outside the battery compartment 10 and is fixedly connected to the first side wall 13 and covers the avoidance through hole. The first connecting pipe 22 and the second connecting pipe 23 both pass through the mounting plate 21 and are integrally formed with the mounting plate 21. The first connecting pipe 22 passes through the avoidance through hole and extends into the battery compartment 10 to communicate with the inlet pipe 11. The second connecting pipe 23 passes through the avoidance through hole and extends into the battery compartment 10 to communicate with the outlet pipe 12. The sealing element 24 is disposed between the first side wall 13 and the mounting plate 21 and surrounds the outer periphery of the first connecting pipe 22 and the second connecting pipe 23.

[0033] In this embodiment, the battery compartment 10 is equipped with an inlet pipe 11 and an outlet pipe 12, forming a closed inlet-outlet liquid circulation, which improves the cooling effect. A clearance through-hole is provided on the first side wall 13 of the battery compartment 10, allowing liquid cooling pipes from outside the battery compartment 10 to extend into the battery compartment 10 and communicate with the inlet pipe 11 and outlet pipe 12. This ensures that the energy storage tank maintains a suitable operating temperature under various operating conditions, greatly extending the service life of key components such as batteries, thereby ensuring the long-term stability and reliability of the energy storage process. In this embodiment, a sealing structure 20 is provided on the first side wall 13 of the battery compartment 10 to seal the clearance through-hole, improving the waterproof effect of the liquid cooling pipeline. Specifically, the sealing structure 20 includes a mounting plate 21, a first connecting pipe 22, a second connecting pipe 23, and a sealing element 24. The mounting plate 21 is disposed outside the battery compartment 10 and is fixedly connected to the first side wall 13, covering the clearance through-hole, reducing the impact of the external environment on the interior of the battery compartment 10. Furthermore, both the first connecting pipe 22 and the second connecting pipe 23 pass through the mounting plate 21 and are integrally formed with the mounting plate 21, which enhances the overall strength of the sealing structure 20 and improves the sealing performance. It also simplifies the installation process and reduces installation costs. During actual installation, the first connecting pipe 22 passes through the clearance through hole and extends into the battery compartment 10 to communicate with the liquid inlet pipe 11, and the second connecting pipe 23 passes through the clearance through hole and extends into the battery compartment 10 to communicate with the liquid outlet pipe 12. This facilitates the flow of refrigerant liquid to ensure the normal operation of the energy storage box. In addition, the sealing element 24 is set between the first side wall 13 and the mounting plate 21 and surrounds the outer periphery of the first connecting pipe 22 and the second connecting pipe 23. During actual installation, the sealing element 24 is deformed by the pressure of the mounting plate 21. The deformed sealing element 24 can seal the gap between the first connecting pipe 22 and the second connecting pipe 23 and the first side wall 13. Compared with the use of fireproof putty to seal the gap in the prior art, the sealing element 24 not only improves the waterproof effect but also improves the aesthetics after sealing.

[0034] In other words, this application provides an integrally formed sealing structure 20, which is installed at the clearance through-hole on the first side wall 13 of the battery compartment 10, improving the waterproof effect inside the battery compartment 10 and facilitating installation. Furthermore, a sealing element 24 is provided on the sealing structure 20, positioned between the sealing structure 20 and the first side wall 13, enhancing the aesthetics of sealing the gap between the first connecting pipe 22 and the second connecting pipe 23 and the first side wall 13.

[0035] Furthermore, the mounting plate 21 can be rectangular, circular, or other shapes. Figures 1 to 3The illustration shows a rectangular mounting plate 21. In this application, the first connecting pipe 22 and the second connecting pipe 23 are fixed to the mounting plate 21 by welding, using a full-weld welding method. This ensures the strength and sealing of the connection between the first connecting pipe 22 and the second connecting pipe 23 and the mounting plate 21, effectively preventing refrigerant leakage and preventing external moisture from entering the battery compartment 10 and causing electrical short circuits. Simultaneously installing the first connecting pipe 22 and the second connecting pipe 23 on a single mounting plate 21, and simultaneously installing the inlet pipe 11 and the outlet pipe 12 within the battery compartment 10, improves heat dissipation efficiency and cooling effect. Furthermore, simultaneously installing the first connecting pipe 22 and the second connecting pipe 23 on the first side wall 13 enhances structural stability and reduces stress concentration. Clearly defined inlet and outlet ports facilitate installation and maintenance, improving work efficiency. It also improves system reliability, ensuring that each battery cell within the battery compartment 10 is adequately cooled, extending battery life. In addition, the sealing element 24 can be a sealant, a sealing gasket, etc. In this application, the sealing gasket is pasted on the mounting plate 21 near the first side wall 13 and surrounds the outer periphery of the first connecting pipe 22 and the second connecting pipe 23, which can improve the sealing effect during actual installation. The sealing element 24 is set between the mounting plate 21 and the first side wall 13, which increases the aesthetics after sealing.

[0036] like Figure 1 and Figure 2 As shown, the sealing structure 20 also includes multiple locking elements 25. The mounting plate 21 has multiple spaced-apart first mounting holes 211. The locking elements 25 are correspondingly inserted into the first mounting holes 211 and threadedly connected to the first sidewall 13. Exemplarily, the locking elements 25 can be screws, bolts, etc. In this application, bolts are preferred, as this improves connection strength and reliability, and ease of installation and disassembly. Furthermore, exemplarily, the number of first mounting holes 211 can be 4, 6, 8, 12, etc., determined according to actual needs, and is not limited in this application. This application shows a case where the number of first mounting holes 211 is 6. With this configuration, the sealing structure 20 is mounted on the first sidewall 13 by multiple locking elements 25, ensuring a sealing effect even if one bolt loosens.

[0037] Furthermore, the sealing element 24 is also provided with a plurality of spaced second mounting holes (not shown in the figure). The first mounting hole 211 and the second mounting hole are provided one-to-one. The locking element 25 passes through the corresponding first mounting hole 211 and the second mounting hole in sequence and is threadedly connected to the first sidewall 13. In this embodiment, the sealing element 24 is a sealing gasket, and the sealing gasket is pasted onto the mounting plate 21. The second mounting holes on the sealing element 24, which correspond one-to-one with the first mounting holes 211, facilitate the smooth threaded connection of the locking element 25 to the first sidewall 13, ensuring the sealing effect. In addition, after the locking element 25 passes through the first mounting hole 211 and the second mounting hole in sequence and is fixedly connected to the first sidewall 13, the locking element 25 can also limit the sealing gasket, preventing it from moving during the locking process, resulting in a better sealing effect. The sealing element 24 is the same size as the mounting plate 21, and the first mounting hole 211 and the second mounting hole are set one-to-one. During the locking process, the two are subjected to relatively uniform force, which can press the two tightly together and ensure that there is no gap between them, thus improving the aesthetics.

[0038] In this embodiment, the first sidewall 13 is provided with multiple through holes (not shown in the figure), and each through hole is provided with a nut (not shown in the figure). The through holes correspond one-to-one with the first mounting hole 211 and the second mounting hole. The sealing structure 20 is fixedly installed on the first sidewall 13 by the locking member 25 and the nut. This arrangement can improve the installation efficiency and accuracy of the sealing structure 20; the use of nuts and locking members 25 in bolt engagement provides a strong connection force, ensuring that the sealing structure 20 is firmly fixed on the first sidewall 13; in addition, pre-embedding the nut in the first sidewall 13 can effectively prevent loosening and falling off, improving installability; it can also improve sealing performance, facilitate maintenance and replacement, and improve aesthetics.

[0039] like Figure 3 As shown, both the first mounting hole 211 and the second mounting hole include oblong holes. Exemplarily, the first mounting hole 211 and the second mounting hole can be either round or oblong; in this embodiment, it is preferred that the first mounting hole 211 and the second mounting hole are oblong holes. This configuration allows the bolt to slide within the hole, facilitating the adjustment of the part's position to adapt to different installation requirements. Furthermore, when installing the sealing structure 20, the oblong hole allows for easy alignment of the parts, reducing assembly difficulty and improving assembly efficiency. It also accommodates manufacturing errors, ensuring that parts can still be installed normally within tolerance limits. In addition, it can improve connection strength, etc.

[0040] like Figure 1 and Figure 2As shown, the energy storage tank also includes a first liquid cooling pipe 30 and a second liquid cooling pipe 31. One end of a first connecting pipe 22 is connected to the first liquid cooling pipe 30, and the other end is connected to the liquid inlet pipe 11. A first connector 40 is provided at the connection points between the first connecting pipe 22 and the first liquid cooling pipe 30, and between the first connecting pipe 22 and the liquid inlet pipe 11. One end of a second connecting pipe 23 is connected to the second liquid cooling pipe 31, and the other end is connected to the liquid outlet pipe 12. A second connector 41 is provided at the connection points between the second connecting pipe 23 and the second liquid cooling pipe 31, and between the second connecting pipe 23 and the liquid outlet pipe 12. In this embodiment, both the first connector 40 and the second connector 41 are welded to the ends of each pipe. At each connection point, two adjacent connectors enhance the connection's strength and sealing, ensuring that the connection will not loosen under vibration or impact; it also effectively prevents liquid leakage. The connectors on both sides of the connection point facilitate the installation and disassembly of adjacent pipes, reduce the risk of failure, and improve safety.

[0041] like Figure 1 and Figure 2 As shown, a first flexible hose 50 can be provided between the first connecting pipe 22 and the liquid inlet pipe 11, with a first connector 40 at both ends of the first flexible hose 50; alternatively, a second flexible hose 51 can be provided between the second connecting pipe 23 and the liquid outlet pipe 12, with a second connector 41 at both ends of the second flexible hose 51. In this embodiment, both the first flexible hose 50 and the second flexible hose 51 are metal hoses. Providing the first flexible hose 50 within the battery compartment 10 ensures that the first connecting pipe 22 connects to the liquid inlet pipe 11, guaranteeing installation feasibility; providing the second flexible hose 51 ensures that the second connecting pipe 23 connects to the liquid outlet pipe 12, guaranteeing installation feasibility. With this configuration, even if some errors occur during installation, the metal hose's flexibility can absorb these errors, allowing for smooth installation.

[0042] Furthermore, both the first connector 40 and the second connector 41 include any one of a quick coupling, a chuck, and a connecting pipe. A connecting pipe refers to a short pipe extending from the opening of the container. During actual installation, a suitable connector can be selected based on actual needs (such as connection and disconnection frequency, sealing performance, and fluid type). In this application, considering actual usage, the chuck end is welded to each pipe at both ends of the first connecting pipe 22, both ends of the second connecting pipe 23, both ends of the first hose 50, both ends of the second hose 51, at least one end of the inlet pipe 11 connected to the first hose 50, and at least one end of the outlet pipe 12 connected to the second hose 51. This ensures a high-strength connection between adjacent pipes. The use of auxiliary connectors at the chuck end also allows for periodic disassembly and maintenance of the pipes.

[0043] like Figure 1 and Figure 2As shown, a first auxiliary connector 60 is provided at the connection point between the first connecting pipe 22 and the first liquid cooling pipe 30, and the first auxiliary connector 60 connects two adjacent first connecting pipes 40. A second auxiliary connector 61 is provided at both ends of the first flexible hose 50, and the second auxiliary connector 61 connects two adjacent first connecting pipes 40. Similarly, a first auxiliary connector 60 is provided at the connection point between the second connecting pipe 23 and the second liquid cooling pipe 31, and the first auxiliary connector 60 connects two adjacent second connecting pipes 41. A second auxiliary connector 61 is provided at both ends of the second flexible hose 51, and the second auxiliary connector 61 connects two adjacent second connecting pipes 41. In this application, auxiliary connectors are required at the points where two adjacent connecting pipes are connected to ensure a tight seal and prevent liquid leakage.

[0044] Furthermore, both the first auxiliary connector 60 and the second auxiliary connector 61 include single-pin clamps or spring clamps. In this embodiment, chuck ends are provided on each pipe. Considering factors such as installation cost and fixing effect, this application preferably uses single-pin clamps for both the first auxiliary connector 60 and the second auxiliary connector 61. Single-pin clamps have good sealing performance, good corrosion resistance, and a long service life. Using them for auxiliary connections and fixing connectors can ensure the stable operation of the system.

[0045] As can be seen from the above embodiments, the energy storage box of this application includes a battery compartment 10 and a sealing structure 20. The sealing structure 20 integrally forms the mounting plate 21, the first connecting pipe 22, and the second connecting pipe 23 by welding, simplifying subsequent installation operations and improving waterproofing. Furthermore, fixing the sealing structure 20 to the clearance through-hole on the first side wall 13 of the battery compartment 10 further enhances the waterproofing effect of the sealing structure 20, preventing moisture from entering the battery compartment 10. In addition, a sealing gasket is pasted on the mounting plate 21. During installation, the sealing gasket seals the gap between the first connecting pipe 22 and the second connecting pipe 23 and the first side wall 13, further improving the sealing performance. Moreover, the sealing gasket is located between the mounting plate 21 and the first side wall 13, which, compared to the use of fireproof putty for sealing in the prior art, improves the aesthetics after sealing. With this configuration, when liquid cooling pipes are used to control the temperature inside the battery compartment 10 to maintain a suitable operating temperature, the service life of critical components such as the battery can be greatly extended, thereby ensuring the long-term stable operation of the energy storage box.

[0046] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0047] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
