Description

Technical Field

[0001] This application relates to the field of energy storage cabinet technology, and more particularly to a louver, a door panel, and an energy storage cabinet. Background Technology

[0002] Current energy storage cabinets, such as lithium battery energy storage cabinets, typically house electrical components such as liquid chillers and air-cooled PCS (Power Conversion Systems). These electrical components generate a significant amount of heat during operation. If this heat is not dissipated in a timely manner, it can cause overheating and even malfunction. Therefore, a well-ventilated louvered structure is crucial for energy storage cabinets. However, energy storage cabinets are generally deployed outdoors, where frequent rainfall causes numerous inconveniences. Rainwater intrusion poses risks such as internal moisture buildup and short circuits. Therefore, while considering heat dissipation, effective rain and dust protection is paramount. Summary of the Invention

[0003] The purpose of this application embodiment is to provide a louver, a door panel, and an energy storage cabinet, wherein the louver has both ventilation and rain and dust protection effects.

[0004] This application provides a venetian blind, the venetian blind comprising: The frame has a mounting cavity, a first opening and a second opening. The mounting cavity is located inside the frame. Along the thickness direction of the frame, the first opening and the second opening are located on opposite sides of the mounting cavity and are both connected to the mounting cavity. Multiple first window leaflets are installed in the mounting cavity and are arranged at intervals along the height direction of the frame. Two adjacent first window leaflets enclose each other to form a first channel. Multiple second window leaflets are installed in the mounting cavity and located on the side of the multiple first window leaflets facing the second opening. The multiple second window leaflets are arranged at intervals along the height direction of the frame. Along the thickness direction of the frame, the projection of each second window leaf onto multiple first window leaves covers an opening of a first channel facing the second window leaf.

[0005] This application provides a louver, which, by setting multiple first slats spaced apart along the height direction of the frame and multiple second slats spaced apart along the height direction of the frame, connects the inner and outer sides of the louver using the first channel between the first slats and the channel between the second slats. This allows heat from the inner side of the louver to enter the louver through the second opening and be transferred to the outside of the louver 710 through the channel between the second slats, the first channel between the first slats, and the first opening, thereby achieving the effect of ventilation and heat dissipation.

[0006] On the other hand, when external objects such as sand and rainwater enter through the first opening of the louvers, the first slats of the louvers act as the first barrier. When the object enters at an angle, and the first slats fail to block it, the object will enter through the first channel between two adjacent first slats. At this time, the projection of the second slat on the first slat can cover the opening of the first channel facing the second slat. The second slat can then act as a second barrier when the first slats fail to block the object, thus effectively preventing the object from splashing into the inside of the louvers. This allows the louvers to not only provide good ventilation and heat dissipation, but also static rainproof and dynamic waterproof performance, and to effectively block sand and dust, thereby preventing external objects from entering and damaging the electrical components inside the louvers.

[0007] In one possible implementation, the frame includes a base plate portion, which is disposed opposite to the first and second window slats along the height direction of the frame. The base plate portion is inclined from the second opening toward the first opening. On the one hand, the angle of inclination of the base plate portion increases the difficulty for foreign objects to enter from the bottom of the frame. On the other hand, it facilitates the timely and rapid discharge of foreign objects that fall onto the base plate portion from the louvers, avoiding the accumulation of foreign objects on the base plate portion.

[0008] In one possible implementation, the base plate portion includes a first end and a second end disposed opposite to each other along the extension direction of the base plate portion, the first end facing the first opening and forming the bottom edge of the first opening, the second end facing the second opening, and the louver also includes a collection member installed on the outside of the frame, the collection member having a collection groove, the opening of the collection groove communicating with the first opening for collecting foreign objects falling from the first opening.

[0009] In one possible implementation, along the height direction of the frame, the opening of the collection trough is flush with the first end, or the opening of the collection trough is located on the side of the first end away from the second end, so that the opening of the collection trough is flush with or lower than the first end, thereby allowing foreign objects falling onto the bottom plate to enter the collection trough along the bottom plate and be collected by the collecting component. Simultaneously, the foreign objects collected in the collection trough can be discharged from the outlet to quickly remove them and prevent their accumulation.

[0010] In one possible implementation, the frame includes a flow guide portion connected to the first end and extending in a direction away from the inner side of the frame along the thickness direction of the bottom plate portion. A collection member is installed on the flow guide portion and forms a collection trough with the flow guide portion. The flow guide portion can guide foreign matter discharged from the bottom plate portion into the collection trough, which helps to improve the collection efficiency of the collection trough.

[0011] In one possible implementation, the first window leaf includes a first partition, a second partition, a third partition, and a guide plate. The second partition is connected to the bottom of the first partition and is inclined toward the first opening. The third partition is connected to the bottom of the first partition and is inclined toward the second opening. The guide plate is connected to the end of the second partition away from the first partition and extends in a direction away from the first partition.

[0012] In one possible implementation, the angle between the second partition and the first partition is β1, where 120°≤β1≤180°. Within this range, the airflow velocity in the core area of ​​the louver is relatively high, which is beneficial to improving the ventilation effect of the louver, while also taking into account a certain degree of dust and rain protection.

[0013] In one possible implementation, two adjacent first window slats include a top window slat and a bottom window slat located at the bottom of the top window slat. The guide plate of the top window slat and the first partition of the bottom window slat are projected onto each other in the thickness direction of the frame. This ensures that when external objects such as sand and rainwater enter the louver, they can be blocked in sequence by the guide plate of the top window slat and the first partition of the bottom window slat, which helps to improve the dustproof and rainproof effect of the louver.

[0014] In one possible implementation, two adjacent first window slats include a top window slat and a bottom window slat located at the bottom of the top window slat. The third partition of the top window slat and the first partition of the bottom window slat are spaced apart in the thickness direction of the frame, so that the heat generated by the electrical components can be transferred out between the third partition of the top window slat and the first partition of the bottom window slat, thus ensuring the heat dissipation effect of the louvers.

[0015] In one possible implementation, the louver further includes a third slat, which is installed in the mounting cavity and located at the bottom of a plurality of first slats. The third slat includes a first plate and a second plate connected to the first plate. The first plate and the guide plate are disposed opposite to each other along the thickness direction of the frame, and the second plate and the second partition are disposed opposite to each other along the height direction of the frame.

[0016] In one possible implementation, the second plate is tilted toward the first opening to guide foreign objects such as rainwater splashed onto the second plate to fall onto the base plate portion.

[0017] In one possible implementation, the second window leaf includes a first baffle and a second baffle, the second baffle being connected to the bottom of the first baffle and inclined toward the first opening.

[0018] In one possible implementation, the angle between the second baffle and the thickness direction of the frame is γ1, where 40°≤γ1≤50°. Within this range, the wind resistance is minimal, thus maximizing the air permeability of the louvers. At this point, the louvers also provide good dust and rain protection.

[0019] In one possible implementation, the blinds further include a fourth slat, which is installed in the mounting cavity and located at the bottom of a plurality of second slats. The fourth slat includes a first connecting plate, a second connecting plate, and a third connecting plate. The second connecting plate is connected between the first connecting plate and the third connecting plate and is inclined toward the first opening.

[0020] This application embodiment also provides a door panel, including a door panel body and louvers as described above. The door panel body is installed in the second opening, and the door panel body is provided with a ventilation hole that penetrates the door panel body and communicates with the mounting cavity.

[0021] In one possible implementation, a plurality of second window leaflets are spaced apart from the door panel body, and the door panel also includes a filter layer installed between the door panel body and the second window leaflets.

[0022] This application embodiment also provides an energy storage cabinet, including a cabinet body and a door panel as described above, the door panel being installed on the cabinet body, and the louvers being located on the side of the door panel body away from the cabinet body.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the energy storage cabinet 1 provided in an embodiment of this application.

[0028] The energy storage cabinet 1 provided in this embodiment can be a lithium battery energy storage cabinet. Specifically, the energy storage cabinet 1 includes a cabinet body 100 and a door panel 700. The cabinet body 100 has a receiving space for accommodating electrical components. Exemplarily, the electrical components include a liquid cooler and an air-cooled PCS (Power Conversion System) in the lithium battery energy storage cabinet. The door panel 700 is installed on the cabinet body 100 and blocks the receiving space.

[0029] Electrical components such as liquid chillers and air-cooled PCS generate a large amount of heat during operation. If this heat is not dissipated in time, it can cause the air-cooled PCS to overheat and reduce its power, or even shut down, and it can also cause the liquid chiller to malfunction. The energy storage cabinet 1 provided in this application embodiment utilizes the door panel 700 for heat dissipation, enabling the energy storage cabinet 1 to meet the heat dissipation requirements of the electrical components. On the other hand, the door panel 700 can also prevent the intrusion of external objects such as sand and rainwater, allowing the energy storage cabinet 1 to be used in scenarios with high dust and rain protection requirements, such as the rainy season and rainy areas in the south, as well as areas with high dust levels, thus avoiding the problem of electrical failures caused by dust and rain accumulation.

[0030] See Figure 2 , Figure 3 and Figure 4 , Figure 2 for Figure 1 The diagram shows the structure of the door panel 700 in the energy storage cabinet 1. Figure 3 for Figure 2 The diagram shows a cross-sectional structure of door panel 700. Figure 4 for Figure 2 The exploded structural diagram of door panel 700 is shown.

[0031] For ease of description, the following definitions are provided. Figure 2 The length direction of the door panel 700 shown is the X-axis direction, the thickness direction is the Y-axis direction, and the height direction is the Z-axis direction. The X-axis, Y-axis, and Z-axis directions are mutually perpendicular. The terms "top," "bottom," and other directional terms used in describing the door panel 700 in this application are based on the appendix to the specification. Figure 2 The description of the orientation shown, with the positive direction of the Z-axis as "top" and the negative direction of the Z-axis as "bottom", does not constitute a limitation on the actual application scenario of the door panel 700.

[0032] The door panel 700 includes a louver 710, a filter layer 730, and a door panel body 750. The door panel body 750 is installed on the louver 710, and the filter layer 730 is installed between the door panel body 750 and the louver 710.

[0033] The venetian blind 710 has a first opening 101 and a second opening 103, which are arranged opposite each other along the thickness direction of the venetian blind 710, and both the first opening 101 and the second opening 103 communicate with the inner side of the venetian blind 710. The venetian blind 710 has fixing holes 711, which penetrate the venetian blind 710. There are multiple fixing holes 711, which are arranged around the second opening 103. The multiple fixing holes 711 include a first fixing hole 701, a second fixing hole 703, and a third fixing hole 705. The first fixing hole 701 and the second fixing hole 703 are located on opposite sides of the second opening 103 along the height direction of the venetian blind 710, and the third fixing hole 705 is located between the first fixing hole 701 and the second fixing hole 703. In this embodiment, the venetian blind 710 is generally rectangular, and the first fixing hole 701 is located at the bottom of the second opening 103, that is, on the side of the second opening 103 facing the negative Z-axis direction. The second fixing hole 703 is located at the top of the second opening 103, that is, on the side of the second opening 103 facing the positive Z-axis direction. In this embodiment, the louver 710 is integrally formed from galvanized steel sheet, which improves the durability of the louver 710 and ensures that the louver 710 can be used for a long time in harsh environments without being easily damaged. In addition, considering that wind, sand and rainwater may contain corrosive substances, galvanized steel sheet with good anti-corrosion properties can be selected and sprayed with repair paint to extend the service life of the louver 710.

[0034] In this embodiment, the filter layer 730 is approximately rectangular. The filter layer 730 is used to filter dust and other debris to improve the dustproof rating of the door panel 700. In this embodiment, the filter layer 730 is a filter cotton layer. In other embodiments, the filter layer 730 can also be other filter layers with filtering effects, such as activated carbon layers, non-woven fabric layers, metal mesh layers, etc., and this application embodiment does not limit this. The thinner and more sparser the filter layer 730, the faster the airflow velocity within the louver 710, which is beneficial for improving the ventilation effect of the louver 710.

[0035] The door panel body 750 is installed at the second opening 103 of the louver 710. The door panel body 750 is provided with a ventilation hole 751 and a mounting hole 753. Both the ventilation hole 751 and the mounting hole 753 penetrate the door panel body 750 along its thickness direction. The ventilation hole 751 communicates with the mounting cavity 720. There are multiple mounting holes 753 arranged around the ventilation hole 751. The multiple mounting holes 753 include a first mounting hole 702, a second mounting hole 704, and a third mounting hole 706. The first mounting hole 702 and the second mounting hole 704 are located on opposite sides of the ventilation hole 751 along the height direction of the door panel body 750, and the third mounting hole 706 is located between the first mounting hole 702 and the second mounting hole 704. In this embodiment, the door panel body 750 is made of wire mesh and is roughly rectangular. The first mounting hole 702 is located at the bottom of the vent hole 751, that is, on the side of the vent hole 751 facing the negative Z-axis. The second mounting hole 704 is located at the top of the vent hole 751, that is, on the side of the vent hole 751 facing the positive Z-axis.

[0036] In this embodiment, the energy storage cabinet 1 also includes fasteners. When assembling the energy storage cabinet 1, the fasteners pass through the fixing holes 711 of the louver 710 and the mounting holes 753 of the door panel body 750, and are fixedly connected to the cabinet body 100 to allow the door panel 700 to be installed on the cabinet body 100. The louver 710 is located on the side of the door panel body 750 facing away from the cabinet body 100, and the first opening 101 of the louver 710 faces the outside of the energy storage cabinet 1. Specifically, there are multiple fasteners. A portion of the fasteners pass through the first fixing hole 701 and the first mounting hole 702 in sequence, a portion of the fasteners pass through the second fixing hole 703 and the second mounting hole 704 in sequence, and another portion of the fasteners pass through the third fixing hole 705 and the third mounting hole 706 in sequence, and are fixedly connected to the cabinet body 100.

[0037] When the energy storage cabinet 1 is in use, on the one hand, the heat generated by the electrical components inside the cabinet 100 can be transferred to the outside of the energy storage cabinet 1 through the ventilation hole 751 of the door panel body 750, the filter layer 730, the second opening 103 of the louver 710, and the first opening 101 of the louver 710, thereby achieving a heat dissipation effect on the electrical components. On the other hand, when external objects such as sand and rainwater enter the inside of the cabinet 100 through the first opening 101 of the louver 710, they can be blocked by the louvers of the louver 710, the filter layer 730, and the door panel body 750, thereby preventing external objects from entering the inside of the cabinet 100 and damaging the electrical components.

[0038] In the energy storage cabinet 1 provided in this embodiment, louvers 710 are integrated into the door panel 700. Through careful structural design, the louvers 710 not only satisfy ventilation and heat dissipation requirements and prevent rainwater intrusion, but also organically integrate with the door panel 700 of the energy storage cabinet 1, forming a single, integral unit. This eliminates the need for adhesive or riveting to fix the louvers 710, simplifying the installation process. Furthermore, since the louvers 710 are integrally molded with the door panel 700, seamlessly integrated, there is no need to purchase and install them separately, saving the cost of separate purchases and reducing production costs, thus demonstrating good economic efficiency. Cost comparison shows that the overall cost of the door panel 700 can be reduced by 17%, resulting in significant cost reduction and further enhancing the market competitiveness of the door panel 700.

[0039] Since the louver 710 and the door panel 700 are integrally molded, the louver 710 is essentially maintenance-free or very easy to clean and maintain. When cleaning the louver 710 is required, there is no need to disassemble it; simply open the door panel 700 of the energy storage cabinet 1 and clean it with water or an air gun. This saves time and effort, reduces maintenance costs and difficulty, and solves the problems of louvers being difficult to maintain and clean, and increasing the frequency of repairs.

[0040] See Figure 5 and Figure 6 , Figure 5 for Figure 4 A schematic diagram of the structure of the louver 710 in the door panel 700 shown. Figure 6 for Figure 5 The diagram shows the structure of the venetian blind 710 from another perspective.

[0041] The venetian blind 710 includes a frame 10 and a slat 713. The slat 713 is installed on the inside of the frame 10. The length direction of the frame 10 is the X-axis direction, the thickness direction is the Y-axis direction, and the height direction of the frame 10 is the Z-axis direction.

[0042] The frame 10 has a mounting cavity 720, a first opening 101, and a second opening 103. The mounting cavity 720 is located inside the frame 10. Along the thickness direction of the frame 10, the first opening 101 and the second opening 103 are located on opposite sides of the mounting cavity 720 and are both in communication with the mounting cavity 720. In this embodiment, the frame 10 includes a bottom plate 11, a top plate 13, and a side plate 15. The bottom plate 11 and the top plate 13 are arranged opposite each other along the height direction of the frame 10. The side plate 15 connects the bottom plate 11 and the top plate 13 and, together with the bottom plate 11 and the top plate 13, encloses the mounting cavity 720.

[0043] The base plate 11 is provided with a first fixing hole 701, which penetrates the base plate 11 along its thickness direction. The base plate 11 includes a base plate portion 111, a flow guiding portion 113, and a first fixing portion 115, which are connected at both ends of the base plate portion 111 along its extension direction. Specifically, the base plate portion 111 includes a first end and a second end disposed opposite to each other along its extension direction. The first end faces the first opening 101 and forms the bottom edge of the first opening 101. The second end faces the second opening 103. In this embodiment, the base plate portion 111 is inclined from the second opening 103 towards the first opening 101, that is, along the height direction of the frame 10, the first end is lower than the second end.

[0044] The flow guiding portion 113 is connected to the first end and extends inward from the frame 10 along the thickness direction of the base plate portion 111. In this embodiment, the angle between the flow guiding portion 113 and the base plate portion 111 is α, where α is an obtuse angle. The first fixing portion 115 is connected to the second end and is located on the same side of the base plate portion 111 as the flow guiding portion 113. The first fixing portion 115 is provided in the first fixing hole 701, which penetrates the first fixing portion 115 along its thickness direction.

[0045] The top plate 13 is provided with a second fixing hole 703, which penetrates the top plate 13 along its thickness direction. The top plate 13 includes a top plate portion 131 and a second fixing portion 133. The top plate portion 131 and the bottom plate portion 111 are disposed opposite each other along the height direction of the frame 10. The second fixing portion 133 is connected to the end of the top plate portion 131 facing the second opening 103. The second fixing portion 133 is provided with a second fixing hole 703, which penetrates the second fixing portion 133 along its thickness direction.

[0046] The side plate 15 is provided with a third fixing hole 705, which penetrates the side plate 15 along its thickness direction. In this embodiment, the side plate 15 includes a first side plate 151 and a second side plate 153. Both the first side plate 151 and the second side plate 153 are connected between the bottom plate 11 and the top plate 13, and are spaced apart along the length direction of the frame 10. Both the first side plate 151 and the second side plate 153 include a side plate portion 152 and a third fixing portion 154. The side plate portion 152 is connected between the bottom plate portion 111 and the top plate portion 131. The third fixing portion 154 is connected to the end of the side plate portion 152 facing the second opening 103. The third fixing portion 154 is provided with a third fixing hole 705, which penetrates the third fixing portion 154 along its thickness direction.

[0047] See also Figure 5, Figure 7 and Figure 8 , Figure 7 for Figure 5 The diagram shows a cross-sectional structure of the louver 710. Figure 8 for Figure 7 The diagram shows the structure of the venetian blind 710 at point A.

[0048] The louver 713 includes a first louver 30, a second louver 50, a third louver 70, and a fourth louver 90. All four louvers are installed in the mounting cavity 720 of the frame 10. In this embodiment, the first louver 30, second louver 50, third louver 70, and fourth louver 90 are formed by bending sheet metal. There are multiple first louvers 30, all installed inside the frame 10 and spaced apart along the height of the frame 10. In this embodiment, the first louvers 30 and the first opening 101 form a ventilation channel, creating a breathable structure and improving the ventilation performance of the louver 710. Two adjacent first louvers 30 enclose a first channel 301, which communicates with the first opening 101.

[0049] In this embodiment, each first window slat 30 is installed on the side plate 15 and extends from the first side plate 151 to the second side plate 153. Each first window slat 30 includes multiple blades, which include a first partition 31, a second partition 33, a third partition 35, and a guide plate 37. The second partition 33 is connected to the bottom of the first partition 31 and is inclined towards the first opening 101. The angle between the second partition 33 and the first partition 31 is β1, where 120°≤β1≤180°. Within this range, the airflow velocity in the core area of ​​the louver 710 is relatively high, which is beneficial to improving the ventilation effect of the louver 710, while also providing a certain degree of dust and rain protection. The third partition 35 is connected to the bottom of the first partition 31 and is inclined towards the second opening 103. The angle between the third partition 35 and the first partition 31 is β2, where β2 is an obtuse angle. The guide plate 37 is connected to the end of the second partition 33 opposite to the first partition 31 and extends in a direction opposite to the first partition 31. The angle between the guide plate 37 and the second partition 33 is β3, which is an obtuse angle. In this embodiment, the first partition 31 extends along the height direction of the frame 10, that is, along the Z-axis direction. The second partition 33 and the third partition 35 are both connected to the end of the first partition 31 along the negative Z-axis direction, and the guide plate 37 extends along the Z-axis direction.

[0050] Two adjacent first window slats 30 include a top window slat 310 and a bottom window slat 330, with the bottom window slat 330 located at the bottom of the top window slat 310 along the height direction of the frame 10. Both the top window slat 310 and the bottom window slat 330 include a first partition 31, a second partition 33, a third partition 35, and a guide plate 37. The guide plate 37 of the top window slat 310 and the first partition 31 of the bottom window slat 330 overlap in the thickness direction of the frame 10, ensuring that when external objects such as sand and rainwater enter the louver 710, they can be blocked sequentially by the guide plate 37 of the top window slat 310 and the first partition 31 of the bottom window slat 330, thereby improving the dustproof and rainproof effect of the louver 710. In addition, the projections of the third partition 35 of the top window sash 310 and the first partition 31 of the bottom window sash 330 in the thickness direction of the frame 10 are spaced apart, that is, the projections of the third partition 35 of the top window sash 310 and the first partition 31 of the bottom window sash 330 in the thickness direction of the frame 10 do not overlap. This facilitates the heat generated by the electrical components inside the cabinet 100 to be transferred out between the third partition 35 of the top window sash 310 and the first partition 31 of the bottom window sash 330, thus ensuring the heat dissipation effect of the louver 710.

[0051] There are multiple second window leaflets 50, all of which are installed inside the frame 10 and located on the side of the multiple first window leaflets 30 facing the second opening 103. In this embodiment, the second window leaflets 50 and the second opening 103 are spaced apart. The multiple second window leaflets 50 are arranged at intervals along the height direction of the frame 10, and two adjacent second window leaflets 50 enclose a second channel 501. Along the thickness direction of the frame 10, the projection of each second window leaflet 50 onto the multiple first window leaflets 30 covers an opening of the first channel 301 facing the second window leaflet 50.

[0052] In this embodiment, each second window slat 50 is mounted on the side panel 15 and extends from the first side panel 151 to the second side panel 153. Each second window slat 50 includes multiple blades, including a first baffle 51 and a second baffle 53. In this embodiment, the first baffle 51 extends along the height direction of the frame 10, that is, along the Z-axis direction. The second baffle 53 is connected to the bottom of the first baffle 51 and is inclined towards the first opening 101. In this embodiment, the angle between the second baffle 53 and the thickness direction of the frame 10 is γ1, 40°≤γ1≤50°. Within this range, the wind resistance is minimal, thereby maximizing the air permeability of the louver 710, while also providing good dust and rain protection. For example, in some embodiments, γ1 is 45°. The angle between the second baffle 53 and the first baffle 51 is γ2, which is an obtuse angle.

[0053] The third window leaf 70 is located at the bottom of the plurality of first window leaves 30. Specifically, the third window leaf 70 is located between the first window leaves 30 and the bottom plate portion 111 of the bottom plate 11, and is spaced apart from both the first window leaves 30 and the bottom plate portion 111. In this embodiment, the third window leaf 70 is mounted on the side plate 15 and extends from the first side plate 151 to the second side plate 153. The third window leaf 70 includes a plurality of blades, each blade including a first plate 71 and a second plate 73 connected to the first plate 71. The first plate 71 and the guide plate 37 of the second window leaf 50 are arranged opposite each other along the thickness direction of the frame 10, and the second plate 73 and the second partition plate 33 of the second window leaf 50 are arranged opposite each other along the height direction of the frame 10. In this embodiment, the first plate 71 extends along the height direction of the frame 10, that is, along the Z-axis direction. The second plate 73 is connected to the bottom of the first plate 71 and extends along the thickness direction of the frame 10, that is, along the Y-axis direction. The angle between the second plate 73 and the first plate 71 is δ, where δ is a right angle. It is understood that in other embodiments, the second plate 73 may also be tilted toward the first opening 101 to guide foreign objects such as rainwater splashed onto the second plate 73 to fall onto the bottom plate portion 111 of the bottom plate 11. In this embodiment, the end of the second plate 73 facing the first opening 101 is located on the side of the guide plate 37 of the first window leaf 30 away from the first opening 101 to avoid blocking foreign objects such as dust or rainwater falling along the guide plate 37 from dripping onto the bottom plate portion 111 of the bottom plate 11.

[0054] The fourth window leaf 90 is located at the bottom of the plurality of second window leaves 50. The fourth window leaf 90 can guide foreign objects such as dust or rainwater falling from the second window leaves 50 to slowly fall to the bottom plate portion 111 of the bottom plate 11, avoiding splashing of foreign objects falling from the second window leaves 50 due to excessive distance between the second window leaves 50 and the bottom plate portion 111. Specifically, the fourth window leaf 90 is located between the second window leaves 50 and the bottom plate portion 111 of the bottom plate 11, the fourth window leaf 90 is spaced apart from the second window leaves 50, and abuts against the bottom plate portion 111. In this embodiment, the fourth window leaf 90 is installed on the side plate 15 and extends from the first side plate 151 to the second side plate 153. The fourth window leaf 90 includes a plurality of blades, the plurality of blades including a first connecting plate 91, a second connecting plate 93 and a third connecting plate 95, the second connecting plate 93 being connected between the first connecting plate 91 and the third connecting plate 95 and inclined toward the first opening 101. In this embodiment, both the first connecting plate 91 and the third connecting plate 95 extend along the height direction of the frame 10, that is, along the Z-axis direction. The angle between the second connecting plate 93 and the first connecting plate 91 is ε1, which is an obtuse angle, and the angle between the third connecting plate 95 and the second connecting plate 93 is ε2, which is also an obtuse angle. The third connecting plate 95 can further guide foreign objects sliding down from the second connecting plate 93 to fall onto the bottom plate portion 111 of the bottom plate 11.

[0055] In this embodiment, the venetian blind 710 also includes a collection member 40, which is installed on the guide portion 113 of the bottom plate 11 in the frame 10, so that the collection member 40 is installed on the outside of the frame 10. The collection member 40 is provided with a collection groove 401 and an outlet 403. The opening of the collection groove 401 communicates with the first opening 101 and is used to collect foreign objects falling from the first opening 101. Along the height direction of the frame 10, the opening of the collection groove 401 is flush with the first end of the bottom plate portion 111 in the bottom plate 11 of the frame 10. Alternatively, the opening of the collection groove 401 is located on the side of the first end of the bottom plate portion 11 away from the second end, that is, the opening of the collection groove 401 is lower than the first end. The outlet 403 communicates with the collection groove 401.

[0056] In this embodiment, the collecting component 40 and the guiding portion 113 enclose a collecting trough 401. Specifically, the collecting component 40 includes a first collecting plate 41 and a second collecting plate 43. The first collecting plate 41 is disposed opposite to the guiding portion 113 of the bottom plate 11, and the second collecting plate 43 is connected between the first collecting plate 41 and the guiding portion 113. The first collecting plate 41, the second collecting plate 43, and the guiding portion 113 enclose the collecting trough 401. The first collecting plate 41 and the guiding portion 113 form the sidewalls of the collecting trough 401, and the second collecting plate 43 forms the bottom wall of the collecting trough 401. In this embodiment, both the first collecting plate 41 and the second collecting plate 43 are elongated, and there are two outlets 403, which are located at opposite ends of the collecting trough 401 along its extension direction.

[0057] See also Figure 8 and Figure 9 , Figure 9 for Figure 3 The diagram shows a side view of the door panel 700.

[0058] In the assembled door panel 700, the second slat 50 of the louver 710 is spaced apart from the door panel body 750, and the filter layer 730 is installed between the door panel body 750 and the second slat 50. When in use, the first opening 101 of the louver 710 faces the outside of the cabinet 100, and the second opening 103 faces the inside of the cabinet 100. Figure 9As shown by the solid arrow, the heat generated by the electrical components inside the cabinet 100 can enter the louver 710 through the ventilation holes 751 and the filter layer 730 of the door panel body 750. On the one hand, the heat is transferred to the first opening 101 through the second channel 501 between multiple second slats 50, the first channel 301 between multiple first slats 30, and the ventilation channel formed by the interval between the first slats 30 and the first opening 101 in the louver 710. On the other hand, the heat can be transferred to the first opening 101 through the gap between the second slats 50 and the fourth slat 90, and the gap between the first slats 30 and the third slat 70 in the louver 710. Finally, the heat is transferred to the outside of the energy storage cabinet 1 from the first opening 101 of the louver 710, thereby achieving heat dissipation for the electrical components.

[0059] like Figure 9 As indicated by the dotted arrow, when external objects such as dust and rainwater enter through the first opening 101 of the louver 710 in the door panel 700, the first slat 30 in the louver 710 forms a first barrier against them. Specifically, the objects are blocked by the first partition 31 and the second partition 33 of the first slat 30, then slide along the inclined surface of the second partition 33 onto the guide plate 37, and fall onto the bottom plate portion 111 of the bottom plate 11 in the frame 10. When objects enter at an angle and through the first channel 301 between the first slats 30, the second slat 50 forms a second barrier, preventing objects from splashing into the filter layer 730, thereby preventing them from damaging the electrical components inside the cabinet 100. Specifically, the objects are blocked by the first baffle 51 and the second baffle 53 of the second slat 50, then slide along the inclined surface of the second baffle 53 onto the bottom plate portion 111 of the bottom plate 11. Because the base plate 111 slopes from the second opening 103 toward the first opening 101, foreign objects falling onto the base plate 111 can slide down along it, then fall through the first opening 101 of the frame 10 and into the collection slot 401 of the collector 40, finally exiting through the outlet 403. The third slat 70 further prevents foreign objects from entering the inside of the louver 710 from its bottom. When foreign objects drift in through the gap between the first slat 30 and the third slat 70, the fourth slat 90 increases the difficulty for them to enter further and also guides objects sliding down from the second slat 50 to fall onto the base plate 111, thus improving the rain and dust protection of the louver 710.

[0060] For rainproof and ventilated louvers, two important indicators must be guaranteed: ventilation performance and rainproof performance. These two are inversely related and require a comprehensive balance. The ventilation area (also known as the opening area) of the louver 710 determines its ventilation performance. A larger effective air intake area for the louver 710 is better, but this is constrained by the arrangement and shape of the electrical components inside the door panel 700. That is, while maintaining the total area, the height of the louver 710 must ensure that the electrical components inside the energy storage cabinet 1 do not interfere with its effective air intake area. Based on theoretical calculations and thermal simulation analysis, this application confirms that the effective air intake area of ​​the louver 710 is not less than 0.24m². 2 The length and height of the louver 710 are determined based on the air intake area of ​​the louver 710.

[0061] In addition, dynamic rainproof performance is an indicator of the 710 louver's rainproof performance during storms, while the rain resistance rate is a grading indicator for dynamic rainproof performance. Static rainproof performance is measured by the airflow velocity in the ventilation zone when raindrops fall vertically in front of the 710 louver and the fan draws in air; this is not graded. For dynamic rainproof performance, besides the rain resistance rate or rainproof rating of the 710 louver, another important factor is the airflow velocity in the core area of ​​the 710 louver. Traditional louvers prioritize ventilation performance, naturally weakening rainproof performance. While suitable for scenarios with low dust and rain protection requirements, they cannot meet the needs of rainy seasons and regions in the south, or areas with high dust levels, as dust and rain accumulation can easily cause electrical faults in the energy storage cabinet 1. In response, this application provides a venetian blind 710. On the one hand, by setting multiple first slats 30 spaced apart along the height direction of the frame 10 and multiple second slats 50 spaced apart along the height direction of the frame 10, the inner and outer sides of the venetian blind 710 are connected by a first channel 301 between the first slats 30 and a second channel 501 between the second slats 50. This allows heat from the inner side of the venetian blind 710 to enter the venetian blind 710 through the second opening 103 and be transferred to the outside of the venetian blind 710 through the second channel 501 between the second slats 50, the first channel 301 between the first slats 30, and the first opening 101, thereby achieving the effect of ventilation and heat dissipation.

[0062] On the other hand, when external objects such as sand and rainwater from the outside environment enter through the first opening 101 of the louver 710, the first slat 30 in the louver 710 can form a first barrier against the external objects. When the external objects enter at an angle and the first slat 30 fails to block them, the external objects will enter through the first channel 301 between two adjacent first slats 30. At this time, the projection of the second slat 50 on the first slat 30 can cover the opening of the first channel 301 facing the second slat 50. The second slat 50 can form a second barrier against the external objects when the first slat 30 fails to block them, thereby effectively preventing external objects from splashing into the inside of the louver 710. This allows the louver 710 to not only meet the requirements of good ventilation and heat dissipation, but also to have static rainproof performance and dynamic waterproof performance, and to have a good blocking effect against sand and dust, thereby preventing external objects from entering and damaging the electrical components inside the louver 710.

[0063] This application presents a simulation experiment on the energy storage cabinet 1 assembled from louvers 710. The simulation results demonstrate that the louvers 710 do indeed possess good rainproof performance, effectively blocking raindrops at a 30° angle and a speed of 3 m / s, significantly reducing the risk of raindrops at a 30° angle and a speed exceeding 3 m / s falling into the energy storage cabinet 1. Real-world environmental testing of the energy storage cabinet 1 also shows good results; the rain resistance rate of the louvers 710 in the energy storage cabinet 1 meets the requirements for outdoor cabinet layouts.

[0064] The louver 710 provided in this application embodiment has both excellent ventilation performance and good rainproof characteristics, making it particularly suitable for applications with high requirements for dust and rain protection, such as rainy seasons and regions in the south, and outdoor locations without building shelter. This greatly expands the application scenarios of the energy storage cabinet 1, and it has very good adaptability in windy and rainy areas and coastal typhoon-prone areas.

[0065] Traditional louvers have simple blade designs and poor flowability, resulting in greater airflow resistance and pressure loss typically between 80 Pa and 120 Pa, leading to higher energy consumption and significantly impacting the operating efficiency of the energy storage cabinet 1. In contrast, the louver 710 provided in this application features a fluid dynamics optimized blade design. The blades of louver 713 adopt a flat plate structure, resulting in more rational and smooth airflow distribution, significantly reducing airflow resistance. Pressure loss is typically less than 50 Pa. The superior flow resistance characteristics of louver 713 enhance the overall performance of louver 710.

[0066] In addition, by setting the bottom plate portion 111 of the bottom plate 11 to be inclined from the second opening 103 toward the first opening 101, on the one hand, the angle of inclination of the bottom plate portion 111 increases the difficulty for foreign objects to enter from the bottom of the frame 10, and on the other hand, it is convenient to discharge foreign objects that fall to the bottom plate portion 111 from the louver 710 in a timely and quick manner, so as to avoid the accumulation of foreign objects in the bottom plate portion 111.

[0067] Furthermore, by setting the opening of the collection groove 401 of the collection member 40 in the louver 710 to be flush with the first end of the bottom plate portion 111 facing the first opening 101, or by setting the opening of the collection groove 401 to be located on the side of the first end facing the second end, so that the opening of the collection groove 401 is flush with or lower than the first end, foreign objects falling onto the bottom plate portion 111 can enter the collection groove 401 along the bottom plate portion 111 and be collected by the collection member 40. At the same time, the foreign objects collected in the collection groove 401 can be discharged from the outlet 403 to quickly discharge foreign objects and prevent foreign objects from accumulating.

[0068] In addition, by setting the bottom plate 11 to include a flow guide portion 113 and forming a collection trough 401 with the flow guide portion 113, the flow guide portion 113 can guide foreign matter discharged from the bottom plate portion 111 into the collection trough 401, which helps to improve the collection efficiency of the collection trough 401.
