Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified.

[0036] Energy storage containers can store a large number of battery modules, and a liquid cooling system is typically installed on them to dissipate heat from the battery modules. Liquid cooling offers advantages such as high heat dissipation efficiency and high system energy density, making it the mainstream heat dissipation solution for energy storage containers. The chiller unit is a key component of the liquid cooling system; the low-temperature coolant provided by the chiller unit enters the cold plates to cool the batteries, ensuring they operate within a suitable temperature range. The air cooler is an indispensable part of traditional chiller units. Due to the limited height of the air cooler, the condenser fan is externally mounted, typically installed at the factory and shipped to the customer's site with the energy storage container. After installation, the fan height will be higher than the top of the container, increasing the overall height of the container during transport and making transportation inconvenient.

[0037] In view of this, embodiments of this application provide an energy storage box to overcome at least one of the above-mentioned technical problems.

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment of the application, the energy storage box includes a fan 10 and a box body 20.

[0039] The housing 20 has a first receiving cavity 21 and a second receiving cavity 22, which are spaced apart along the length Y direction of the housing 20. When the fan 10 is stowed, it is at least partially housed within the first receiving cavity 21. When installed, the fan 10 is located within the second receiving cavity 22 along the height X direction of the housing 20, and at least partially outside the second receiving cavity 22. It is understood that if the energy storage box needs to be transported, the fan 10 can be stowed away, with at least a portion of it housed within the first receiving cavity 21. This reduces the overall height of the energy storage box. When the fan 10 is completely housed within the first receiving cavity 21, the overall height of the energy storage box can be reduced to the maximum extent possible. In other words, the fan 10 will not increase the overall size of the energy storage box during transport, and the fan 10 will not affect the transport of the energy storage box. After the energy storage box is transported to its destination, the fan 10 is installed. The fan 10 is installed in the second receiving cavity 22 along the height X direction of the box body 20, allowing the fan 10 to dissipate heat from the internal structure of the second receiving cavity 22. The fan 10 can be partially or completely installed outside the second receiving cavity 22, achieving heat dissipation without excessively occupying the internal space of the second receiving cavity 22, facilitating the installation of other internal structures of the energy storage box. The fan 10 can be installed on the box body 20 through the storage structure 30. The storage structure 30 can move the fan 10 between the stored state and the installed state. If the energy storage box needs to be transported, the storage structure 30 can be used to move the fan 10 into the stored state. At this time, at least part of the fan 10 is located inside the first receiving cavity 21. During the transportation of the energy storage box, the fan 10 will not increase the overall height of the energy storage box, or the increase in height will be very small, and will not affect the transportation of the energy storage box. When the storage structure 30 is in its stored state, it can be completely, partially, or even completely located outside the energy storage box. Since the storage structure 30 is only used to move the fan 10, its size does not need to be large. Even if the storage structure 30 is partially or completely located outside the energy storage box, it will not significantly increase the size of the energy storage box, and will have little or no impact on its transportation. After the energy storage box is transported to its destination, the fan 10 can be quickly moved outside the box 20 using the storage structure 30. Then, the fan 10 can be manually moved or transported using other structures to a suitable installation location, allowing it to be in the installation state.

[0040] Please see Figure 1 and Figure 3In conjunction with the above embodiments, in some embodiments, when the fan 10 is installed, the maximum distance from the top of the fan 10 to the bottom of the housing 20 is H1, and when the fan 10 is stowed, the maximum distance from the top of the fan 10 to the bottom of the housing 20 is H2, satisfying H1 > H2. It can be understood that when the fan 10 is stowed, its height is less than when it is installed. The height of the fan 10 in the stowed state is reduced compared to its installed state. When the energy storage box is transported, the fan 10 is in a stowed state, meaning the overall height of the energy storage box is reduced (compared to when the fan 10 is installed), reducing the space occupied during transportation and improving the transportation efficiency of the energy storage box and the fan 10.

[0041] Please see Figure 1 , Figure 2 and Figure 3 In conjunction with the above embodiments, in some embodiments, the energy storage box includes a flipping component 31, which is connected to both the box body 20 and the fan 10, allowing the fan 10 to be flipped between a storage position and an installation position. It is understood that during transportation of the energy storage box, the flipping component 31 can support at least a portion of the fan 10 within the first receiving cavity 21, ensuring that at least a portion of the fan 10 is located inside the energy storage box without increasing its size during transportation, thus facilitating transport. After the energy storage box reaches its destination, the flipping component 31 can be flipped from the storage position to the installation position, causing the fan 10 to flip to the outside of the box body 20, facilitating the installation of the fan 10.

[0042] Please see Figure 1 , Figure 2 and Figure 3 In conjunction with the above embodiments, in some embodiments, the flipping member 31 includes: a flipping part 311 and a support plate 312.

[0043] The flip-up part 311 is connected to the housing 20. The support plate 312 is connected to the flip-up part 311 and also to the fan 10. The support plate 312 allows the fan 10 to flip between a storage position and an installation position via the flip-up part 311. It is understood that the flip-up part 311 can be connected to the housing 20 via the flip-up part 311, and the flip-up part 311 can be a rotatable structure such as a folding hinge or a rotating shaft. The support plate 312 is connected to both the flip-up part 311 and the fan 10. The support plate 312 can be flipped via the flip-up part 311, and the flip angle can be set as needed. The support plate 312 drives the fan 10 to move in the same direction, thereby moving the fan 10 from inside the first receiving cavity 21 to outside the housing 20, facilitating the installation of the fan 10 in a suitable position. The support plate 312 can be a plate structure or a frame structure, as long as it facilitates the installation of the fan 10.

[0044] Please see Figure 1 and Figure 3 In conjunction with the above embodiments, in some embodiments, when the fan 10 is installed, the support plate 312 covers the top opening of the second receiving cavity 22; when the fan 10 is stored, the support plate 312 covers the top opening of the first receiving cavity 21. It is understood that when the fan 10 is stored, the support plate 312 connected to the fan 10 can cover the top opening of the first receiving cavity 21, blocking foreign objects from falling into the first receiving cavity 21 and damaging its internal structure (such as a pressure relief valve). When the fan 10 is installed, the support plate 312 can cover the top opening of the second receiving cavity 22, preventing air leakage inside the second receiving cavity 22 and improving air cooling efficiency.

[0045] Please see Figure 4 , Figure 5 , Figure 6 and Figure 7 In conjunction with the above embodiments, in some embodiments, the energy storage box includes a support member 32. When the fan 10 is stowed, the support member 32 is located within the first receiving cavity 21 and is detachably connected to both the box body 20 and the fan 10. It is understood that the support member 32 can be directly or indirectly connected to the box body 20. During transportation of the energy storage box, the support member 32 can support at least a portion of the fan 10 within the first receiving cavity 21, allowing part or all of the fan 10 to be located inside the energy storage box, minimizing the size of the energy storage box during transportation and facilitating its transport. After the energy storage box is transported to its destination, the support member 32 can move the fan 10 completely outside the box body 20, facilitating the installation of the fan 10.

[0046] Please see Figure 4 , Figure 5 , Figure 6 and Figure 7 In conjunction with the above embodiments, in some embodiments, the support member 32 includes a telescopic part 321 and a mounting part 322.

[0047] The telescopic part 321 is located within the first receiving cavity 21 and is detachably connected to the housing 20. The mounting part 322 is located within the first receiving cavity 21 and is connected to the telescopic part 321. When the fan 10 is retracted, it is detachably connected to the mounting part 322 on the side opposite to the telescopic part 321. It is understood that the support member 32 can be directly or indirectly connected to the housing 20 via the telescopic part 321 (e.g., the telescopic part 321 can be directly connected to the side wall of the first receiving cavity 21, or indirectly connected to the side wall of the first receiving cavity 21 via a load-bearing structure; it is generally not connected to the bottom wall of the first receiving cavity 21, as this would affect the use of the explosion relief assembly 50). The telescopic part 321 and the housing 20 are detachably directly or indirectly connected via bolts, clips, or other structures, which facilitates the installation and disassembly of the telescopic part 321 and the mounting part 322, and is beneficial for the recycling and reuse of the telescopic part 321 and the mounting part 322, avoiding resource waste. The telescopic part 321 can be a telescopic cylinder or telescopic linkage, or other structure capable of pushing the fan 10. The mounting part 322 connects to both the telescopic part 321 and the fan 10. The fan 10 can be detachably connected to the mounting part 322 via bolts, clips, or other structures, facilitating quick connection and separation of the fan 10 and the mounting part 322. The telescopic part 321 can push the fan 10 through the mounting part 322, moving the fan 10 from inside the first receiving cavity 21 to outside the housing 20, facilitating installation of the fan 10 in a suitable position. The mounting part 322 can be a plate-like structure or a frame structure, allowing the fan 10 to be easily mounted on it.

[0048] Please see Figure 4 , Figure 5 and Figure 6In conjunction with the above embodiments, in some embodiments, the energy storage box further includes an explosion venting component 50, which is located within the first receiving cavity 21 and connected to the box body 20; the support member 32 also includes a bearing portion 323. The bearing portion 323 is located within the first receiving cavity 21 and is detachably connected to the box body 20. The bearing portion 323 divides the first receiving cavity 21 into a first chamber 211 and a second chamber 212 spaced apart along the height direction X of the box body 20. The support member 32 is located in the first chamber 211, and the explosion venting component 50 is located in the second chamber 212. The bearing portion 323 is located on the side of the telescopic portion 321 opposite to the mounting portion 322 and is detachably connected to the telescopic portion 321. It is understood that the bearing portion 323 can be provided inside the first receiving cavity 21, and the bearing portion 323 can be detachably connected to the box body 20 by bolts, clips, or other structures, which facilitates the disassembly and assembly of the bearing portion 323 as needed, and is beneficial for the recycling and reuse of the bearing portion 323, avoiding resource waste. The support portion 323 can divide the first receiving cavity 21 into a first chamber 211 and a second chamber 212 along the height direction X. The explosion relief assembly 50 is located in the second chamber 212. The support portion 323 can provide a certain degree of protection for the explosion relief assembly 50, preventing foreign objects or impurities from falling onto the explosion relief assembly 50 and affecting its normal operation. At the same time, the telescopic portion 321 can be detachably connected to the support portion 323, using the support portion 323 as a force-bearing structure, so that the telescopic portion 321 is indirectly connected to the housing 20 through the support portion 323. The connection between the telescopic portion 321 and the support portion 323 allows the telescopic portion 321 to be set along the height direction X, and the fan 10 to move in the height direction X. The structural strength requirements and installation requirements of the telescopic portion 321 are not high (compared to the telescopic portion 321 being directly installed at an angle on the side wall of the first receiving cavity 21), reducing the structural requirements and installation difficulty of the telescopic portion 321.

[0049] Please see Figure 1 , Figure 8 , Figure 9 and Figure 10In conjunction with the above embodiments, in some embodiments, the energy storage box includes a cooling component 40. The cooling component 40 is located within the second receiving cavity 22 and connected to the box body 20. When the fan 10 is in the installed state, it can be positioned on one side of the cooling component 40 along the height direction X, facilitating heat dissipation from the cooling component 40 by the fan. The cooling component 40 includes a first cooling plate 41 and a second cooling plate 42, arranged at intervals along the length direction Y or the width direction Z of the box body 20. The first cooling plate 41 and the second cooling plate 42 are parallel, or the extending directions of the first cooling plate 41 and the second cooling plate 42 intersect. It is understood that the cooling component 40 generally includes a first cooling plate 41 and a second cooling plate 42. Heat from the internal structure of the energy storage box can be transferred to the first cooling plate 41 and the second cooling plate 42. Since the first cooling plate 41 and the second cooling plate 42 have a large surface area, heat dissipation can be increased. The fan 10 generates airflow, blowing air across the first cooling plate 41 and the second cooling plate 42 to accelerate heat transfer and dissipation. The first cooling plate 41 and the second cooling plate 42 can be arranged in parallel, reducing airflow resistance, accelerating heat dissipation, and lowering the energy consumption of the fan 10. Alternatively, the first cooling plate 41 and the second cooling plate 42 can be arranged in a "V" or "V" shape, with the first cooling plate 41 and the second cooling plate 42 tilted. This arrangement reduces the height of the first cooling plate 41 and the second cooling plate 42, thus reducing the space they occupy and lowering the overall height of the housing 20, which is beneficial for transporting the energy storage box.
