[0036] The embodiments, implementation methods, and related technical features of this application can be combined and substituted for each other without conflict.

[0037] The applicant noted that with the development of large-scale energy storage systems, different user groups with varying requirements and various harsh on-site environments have emerged, correspondingly necessitating higher safety and protection requirements for the system itself. Currently, the structural solutions for the air outlets of energy storage systems employ either a rainproof cover with self-closing louvers on the sides or a bend structure with wire mesh at the bottom. These methods still present some hidden dangers. When using a rainproof cover with self-closing louvers on the sides, the louvers rely on their own weight to close. During strong winds, sandstorms, or heavy rainfall, the louvers risk remaining open, allowing sand and water to enter through the louver openings. When using a bend structure with wire mesh at the bottom, higher mesh counts result in smaller gaps, affecting airflow efficiency; conversely, lower mesh counts result in larger gaps, making it easier for sand and rainwater to enter. While the current mesh count meets the protection level requirements of the energy storage system, there is still a risk of sand and water ingress during strong winds, sandstorms, and heavy rainfall.

[0038] In view of this, this application provides a ventilation structure including a housing 1 and a first filter assembly 2. The housing 1 has an air inlet 10 and an air outlet 11. The air inlet 10 is located on one side of the housing 1 along a first direction X, and the air outlet 11 is located on one side of the housing 1 along a second direction Y. The first direction X and the second direction Y intersect. The housing 1 includes a first sidewall 12 opposite to the air inlet 10 in the first direction X, which guides the airflow to a first area of ​​the air outlet 11. The first filter assembly 2 is disposed inside the housing 1 and includes a guide plate 20, which guides the airflow to a second area of ​​the air outlet 11. At least a portion of the second area is located outside the first area. With this configuration, on the one hand, the first filter assembly 2 can filter and protect against external rainwater or sand infiltration; on the other hand, the guide plate 20 guides the airflow, ensuring uniform wind load on the air outlet 11 and forming a stable wind direction barrier, thereby improving waterproofing and sandproofing capabilities.

[0039] The ventilation structure and energy storage system of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0041] Reference Figure 1 and Figure 2 This application provides a ventilation structure, which includes a housing 1 and a first filter assembly 2. The housing 1 has an air inlet 10 and an air outlet 11. The air inlet 10 is located on one side of the housing 1 along a first direction X, and the air outlet 11 is located on one side of the housing 1 along a second direction Y. The first direction X and the second direction Y intersect. For example, the first direction X and the second direction Y are perpendicular to each other. The housing 1 can be an elbow structure, with the air inlet 10 located at the side end of the elbow structure and the air outlet 11 located at the bottom end of the elbow structure. The air inlet 10 of the housing 1 connects with the air outlet channel of the housing 100, thereby allowing airflow inside the housing to be discharged. (Refer to...) Figure 6Typically, the enclosure 100 is equipped with an exhaust system to remove heat generated by the electrical components within the enclosure 100 and to guide the air within the enclosure 100 toward the air inlet 10 of the housing 1. The housing 1 includes a first sidewall 12 opposite to the air inlet 10 in the first direction X. The first sidewall 12 is used to guide the airflow to a first area of ​​the air outlet 11, as shown in Figure 1. Figure 5 The first region is region A shown in the figure; the first filter assembly 2 is disposed inside the housing 1, and the first filter assembly 2 includes a guide plate 20, which is used to guide the airflow to the second region of the air outlet 11. At least part of the second region is located outside the first region, as shown in the figure. Figure 5 The first area is area B shown in the figure. With this configuration, on the one hand, the first filter component 2 can filter and protect against external rainwater or sand infiltration; on the other hand, the guide plate 20 directs the airflow to ensure that the wind load on the air outlet 11 is uniform, forming a stable wind direction barrier, thereby improving the waterproof and sandproof capabilities.

[0042] In some embodiments, refer to Figure 2 The housing 1 includes two second sidewalls 13 arranged opposite each other along a third direction Z, and the two second sidewalls 13 are respectively connected to a first sidewall 12; the third direction Z intersects with the first direction X and the second direction Y respectively; the first sidewall 12 is arranged opposite to the air inlet 10 along the first direction X, and the first sidewall 12 is used to guide the airflow blown out of the housing 100 along the air inlet 10 to the first area of ​​the air outlet 11. The two second sidewalls 13 are arranged opposite each other along the third direction Z and are respectively connected to the two side edges of the first sidewall 12 to form lateral constraints on the airflow.

[0043] In some embodiments, refer to Figure 1 The ventilation structure includes a first connecting part 3, which is connected to the second sidewall 13 and the first filter assembly 2. The first connecting part 3 serves to fix the first filter assembly 2. For example, the first connecting part 3 is fixed to the second sidewall 13 by fasteners or a snap-fit ​​structure, and the first filter assembly 2 is detachably connected to the first connecting part 3, thereby ensuring that the first filter assembly 2 is easy to disassemble and replace.

[0044] In some embodiments, refer to Figure 3 The first connecting part 3 includes a first connecting segment 30, a second connecting segment 31, and a third connecting segment 32. The first connecting segment 30 is fixed to the second side wall 13. The first connecting segment 30 and the third connecting segment 32 are spaced apart in the third direction Z. The second connecting segment 31 extends along the third direction Z and connects to the first connecting segment 30 and the third connecting segment 32 respectively. The third connecting segment 32 is detachably connected to the first filter assembly 2. This arrangement ensures the connection stability of the first filter assembly 2 and also ensures that the first filter assembly 2 is easy to disassemble and replace.

[0045] In some embodiments, refer to Figure 1 The first filter assembly 2 includes a first fixing part 21 and a first filter screen (not shown). The first filter screen is disposed on the first fixing part 21. One side of the first fixing part 21 is connected to the first connecting part 3, and the other side of the first fixing part 21 is connected to the guide plate 20. The first fixing part 21 can be a frame structure, and its two ends along the third direction Z are detachably connected to the first connecting part 3 by fasteners or snap-fit ​​structures. The first filter screen is fixed to the first fixing part 21, thereby intercepting impurities such as sand and rainwater in the airflow.

[0046] In some embodiments, refer to Figure 4 The first fixing part 21 is connected to the first side wall 12 on the side opposite to the air inlet 10 by fasteners or snap-fit ​​structure, which can further improve the connection stability between the first filter component 2 and the housing 1.

[0047] In some embodiments, refer to Figure 5 The deflector 20 has a guiding slope 200, which intersects with the first direction X and the second direction Y. It is understood that the deflector 20 is inclined along the second direction Y toward the first sidewall 12. The deflector 20 is used to guide at least a portion of the airflow to the second area of ​​the air outlet 11. This arrangement ensures that the wind load is uniform in the first and second areas of the air outlet 11, thereby forming a stable wind direction barrier and improving the waterproof and sandproof capabilities of the ventilation structure.

[0048] In some embodiments, the ventilation structure includes a second filter assembly 4 located within the housing 1 and disposed at the air outlet 11. The second filter assembly 4 is used in combination with the first filter assembly 2 to further improve the waterproof and sandproof capabilities of the ventilation structure. The ventilation structure includes a second connecting portion 5, which is connected to the first connecting portion 3 and the second filter assembly 4 respectively. The second connecting portion 5 serves to fix the first connecting portion 3 and the second filter assembly 4. Specifically, the first connecting portion 3 includes a first connecting segment 30, a second connecting segment 31, and a third connecting segment 32 connected in sequence. The first connecting segment 30 is fixed to the second sidewall 13. The first connecting segment 30 and the third connecting segment 32 are spaced apart in the third direction Z. The second connecting segment 31 extends along the third direction Z and is connected to the first connecting segment 30 and the third connecting segment 32 respectively. The end of the second connecting portion 5 near the first filter assembly 2 is connected to the second connecting segment 31, and the end of the second connecting portion 5 away from the first filter assembly 2 is connected to the second filter assembly 4. The third connecting segment 32 is detachably connected to the first filter assembly 2. The second connecting part 5 can be connected to the second connecting section 31 and the second filter component 4 respectively by fasteners or snap-fit ​​structures. This configuration is simple, the connection is stable, and the second filter component 4 is easy to disassemble and replace.

[0049] In some embodiments, refer to Figure 1 The second filter assembly 4 includes a second fixing part 40 and a second filter screen (not shown) connected to each other. The second filter screen is disposed at the air outlet 11, and the second fixing part 40 is connected to the housing 1. The second fixing part 40 can be a frame structure. The side of the second fixing part 40 near the air inlet 10 along the first direction X can be detachably connected to the second connecting part 5 by fasteners or a snap-fit ​​structure. The side of the second fixing part 40 away from the air inlet 10 along the first direction X can be detachably connected to the first sidewall 12 by fasteners or a snap-fit ​​structure. The second filter screen is fixed to the second fixing part 40, thereby intercepting impurities such as wind sand and rainwater outside the air outlet 11.

[0050] In some embodiments, refer to Figure 5 The first region and the second region are arranged along the first direction X, with the second region positioned closer to the air inlet 10 relative to the first region. The first region is formed by airflow guided by the first sidewall 12 of the housing 1, and the second region is formed by airflow guided by the guide plate 20. The arrangement of the first region and the second region along the first direction X ensures uniform wind load on the air outlet 11, forming a stable wind direction barrier, thereby improving waterproof and sandproof capabilities.

[0051] In some embodiments, refer to Figure 5The ventilation structure includes multiple guide vanes 20, which are spaced apart. For example, the ventilation structure includes two guide vanes 20 with their guide slopes 200 facing the same direction. The spacing between the two guide vanes 20 is adjusted according to design requirements to ensure that the airflow entering from the inlet 10 covers the entire cross-section of the outlet 11. The spaced guide vanes 20 divide the airflow into multiple parallel sub-airflows, further homogenizing the airflow distribution through multi-segment guidance, further ensuring uniform wind load on the outlet 11, forming a stable wind direction barrier, thereby improving waterproofing and sandproofing capabilities.

[0052] Reference Figure 6 According to a second aspect of this application, an energy storage system is provided, including a housing 100 and the aforementioned ventilation structure. The housing 100 has an air outlet channel, and the air inlet 10 of the ventilation structure is connected to the air outlet channel. Therefore, this energy storage system can possess all the technical features and beneficial effects of the aforementioned ventilation structure, which will not be elaborated further here.

[0053] In some embodiments, refer to Figure 1 A sealing element 6 is sandwiched between the housing 100 and the ventilation structure to ensure that the air outlet channel of the housing 100 and the housing 1 of the ventilation structure form a sealed connection, ensuring that the airflow is discharged only through the first filter component 2 and the second filter component 4, preventing impurities such as wind, sand and rainwater from seeping in.
