Ventilation structure, energy storage cabinet and energy storage system

Abstract

A ventilation structure, an energy storage cabinet and an energy storage system. The ventilation structure comprises a mounting body and flow guide members, wherein the mounting body is configured to be assembled and connected to a ventilation opening of the energy storage cabinet; all flow guide assemblies are connected to the mounting body, and each group of flow guide assemblies comprise a plurality of flow guide members, which are arranged in a first direction intersecting with a ventilation direction of the energy storage cabinet, and on one side of the ventilation direction, each flow guide member is provided with a recessed cavity having an opening. The ventilation structure is additionally arranged at the ventilation opening, and when noise is transmitted outwards by means of the ventilation opening, the noise can be collided between the flow guide members so as to be eliminated, thereby achieving the effect of reducing noise. When the ventilation opening serves as an air inlet, the opening of the recessed cavity of each flow guide member is made to face the interior of the energy storage cabinet, such that an airflow, which is blown in from outside to inside, is normally guided and is smoothly blown into the energy storage cabinet, and noise transmitted from the inside to the outside can be absorbed by the recessed cavity of each flow guide member, thereby eliminating the noise. In this way, the flow guide members can not only perform flow guiding, but can also perform noise reduction, and thus can prevent noise from transmitting outwards while achieving ventilation and heat dissipation.

[0002] This application relates to the field of energy storage technology, specifically to ventilation structures, energy storage cabinets, and energy storage systems. Background Technology

[0003] Currently, the heat dissipation equipment in outdoor liquid-cooled energy storage cabinets needs to ventilate and circulate with the external environment and dissipate heat due to functional requirements, so as to ensure the normal operation of the devices.

[0004] However, during operation, the internal cooling fans and other equipment generate noise, which affects the external environment.

[0005] Summary of the Invention

[0006] Therefore, it is necessary to provide a ventilation structure, energy storage cabinet, and energy storage system that can suppress the transmission of noise while achieving ventilation and heat dissipation.

[0007] A ventilation structure for an energy storage cabinet, the ventilation structure comprising:

[0008] Mounting body, for assembly and connection with the ventilation opening of the energy storage cabinet; and

[0009] At least one set of flow guiding components is connected to the mounting body. Each set of flow guiding components includes a plurality of flow guiding elements arranged along a first direction, which intersects with the ventilation direction of the energy storage cabinet. The flow guiding elements form a cavity with an opening on one side of the ventilation direction.

[0010] In one embodiment, the ventilation structure further includes a silencing element that covers the side of the air guide facing the interior of the energy storage cabinet in the ventilation direction.

[0011] In one embodiment, the ventilation structure includes at least three sets of the flow guiding components, all of which are arranged sequentially at intervals along the ventilation direction, and the flow guiding elements of adjacent sets of the flow guiding components are staggered.

[0012] In one embodiment, the mounting body includes a top plate and a bottom plate extending along the first direction, all of the flow guiding components are located between the top plate and the bottom plate, and the opposite ends of each flow guiding component are respectively connected to the top plate and the bottom plate.

[0013] In one embodiment, the mounting body further includes two side plates, which together with the top plate and the bottom plate form a frame and form flanges on all sides.

[0014] In one embodiment, at least a portion of the flow guiding assembly further includes an arc-shaped flow guide disposed on the side plate.

[0015] In one embodiment, at least some of the guide elements in each group of the airflow assemblies are spaced apart from each other; along the ventilation direction, the projections on a plane perpendicular to the ventilation direction, all the guide elements together cover the ventilation opening.

[0016] In one embodiment, the longitudinal direction of the flow guide intersects the ventilation direction, the cross-section of the flow guide perpendicular to its longitudinal direction is a Y-shaped structure, and the vertical direction of the Y-shaped structure is parallel to the ventilation direction.

[0017] An energy storage cabinet, the energy storage cabinet including a cabinet body and the above-mentioned ventilation structure.

[0018] In one embodiment, at least one of the cabinet door, top panel, and bottom panel of the cabinet has a ventilation opening, and at least a portion of the ventilation opening is provided with the ventilation structure.

[0019] In one embodiment, the cabinet door has a ventilation opening that serves as an air inlet. The air inlet is equipped with the ventilation structure, and the opening of the cavity of the air guide faces the interior of the cabinet. The ventilation structure also includes a sound-absorbing component that covers the cavity wall of the cavity.

[0020] An energy storage system, the energy storage system comprising the above-described ventilation structure or the above-described energy storage cabinet;

[0021] The energy storage system also includes at least one of a battery system, a liquid cooling unit, and an electrical system.

[0022] The aforementioned ventilation structure, energy storage cabinet, and energy storage system attach the ventilation structure to the vent of the energy storage cabinet. Airflow through the vent also passes through the ventilation structure. Noise, as it is transmitted outward through the ventilation structure, is amplified and neutralized by collisions between the airflow guides, achieving noise reduction. When the vent is an air inlet, the ventilation structure can be strategically positioned so that the concave openings of its airflow guides face inward towards the energy storage cabinet, i.e., towards the noise source. Airflow blowing inward is guided smoothly into the interior by the airflow guides, while noise transmitted outward is absorbed and neutralized by the concave openings of the airflow guides. Thus, the ventilation structure integrates noise reduction functionality, providing both airflow guidance and noise reduction. This results in a simple yet highly integrated structure, easily attachable to vents to simultaneously achieve ventilation and heat dissipation while suppressing outward noise transmission.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0047] Please refer to Figures 1 to 8. An embodiment of this application provides a ventilation structure 100, including a mounting body 10 and at least one set of flow guiding components 3. The mounting body 10 is used for assembly and connection with the ventilation opening 210 of the energy storage cabinet 200. All flow guiding components 3 are connected to the mounting body 10. Each set of flow guiding components 3 includes multiple flow guiding elements 30 arranged along a first direction (X direction as shown in Figure 5), which intersects with the ventilation direction of the energy storage cabinet 200 (Y direction as shown in Figure 5). Each flow guiding element 30 forms a recessed cavity 31 with an opening on one side in the ventilation direction.

[0048] Understandably, the ventilation structure 100 is installed at the vent 210 via the mounting body 10. After installation, the ventilation structure 100 covers or partially nests within the vent 210, allowing ventilation at the vent 210 to be carried out through the ventilation structure 100. All airflow guides 30 are connected to the mounting body 10 and are uniformly installed at the vent 210 of the energy storage cabinet 200 via the ventilation structure 100. The airflow passing through the vent 210 must be guided by the airflow guide assembly 3.

[0049] Understandably, the vent 210 of the energy storage cabinet 200 can be either an air inlet 211 or an air outlet 212. In order to achieve the basic function of ventilation, the airflow guiding component 3 will not completely block the vent 210, but only play the role of guiding or changing the flow direction and state of the airflow at the vent 210.

[0050] Specifically, each air guide 30 has a windward side and a leeward side on its two sides in the ventilation direction. The windward side of the air guide 30 has a guiding function, with lower wind resistance, enabling it to guide airflow. On the leeward side, the air guide 30 forms the aforementioned cavity 31, which has higher wind resistance and can absorb and eliminate noise through the cavity 31. In other words, the drag coefficients of the air guide 30 on the windward and leeward sides are configured to be different. Under the same conditions, the wind resistance generated by airflow blowing on the windward and leeward sides of the air guide 30 is different.

[0051] The drag coefficient on the leeward side may be no less than 0.8, and may specifically be 0.8, 0.9 or 1, etc. The drag coefficient on the windward side may be no greater than 0.5, and may specifically be 0.5, 0.4, 0.3, 0.2 or 0.1, etc., without specific limitations.

[0052] In one specific embodiment, the ventilation structure 100 is used on the housing 410 of the energy storage cabinet 200 or the energy storage system 400 to eliminate the operating noise of the equipment inside the energy storage cabinet 200 or the operating noise of the equipment located in the housing of the energy storage system 400.

[0053] The aforementioned ventilation structure 100 is attached to the vent 210, and the airflow passing through the vent 210 also flows through the ventilation structure 100. Noise, as it is transmitted outward through the ventilation structure 100, is amplified and eliminated by collisions between the guide elements 30, achieving a noise reduction effect. When the vent 210 is an air inlet 211, the ventilation structure 100 can be strategically arranged so that the openings of the concave cavities 31 of its guide elements 30 face the interior of the energy storage cabinet 200, i.e., towards the noise source. Airflow blowing in from the outside is guided smoothly into the interior by the guide elements 30, while noise transmitted from the inside out is absorbed and eliminated by the concave cavities 31 of the guide elements 30. Thus, the ventilation structure 100 integrates noise reduction functionality, both guiding airflow and reducing noise. This results in a simple structure with high integration, making it easy to attach to the vent 210, thereby achieving ventilation and heat dissipation while suppressing noise transmission outward.

[0054] In some embodiments, the ventilation structure 100 further includes a silencing element 70 (as shown in Figures 12 and 15), which covers the side of the air guide 30 facing the interior of the energy storage cabinet 200 in the ventilation direction.

[0055] The silencing component 70 can be made of materials such as sound-absorbing cotton, sponge, or fleece. The flow guide 30 is covered with the silencing component 70 on the side facing the inside of the energy storage cabinet 200, that is, the side facing the noise source, so that when the noise is transmitted to the surface of the flow guide 30, it is silenced by the silencing component 70.

[0056] Understandably, for the ventilation structure 100 located at the air inlet 211, the opening of the cavity 31 of the air guide 30 faces the interior of the energy storage cabinet 200, so the silencing component 70 is applied to the cavity wall of the cavity 31. For the ventilation structure 100 located at the air outlet 212, the opening of the cavity 31 of the air guide 30 faces away from the interior of the energy storage cabinet 200, so the surface facing the interior of the energy storage cabinet 200 is covered with the silencing component 70.

[0057] Thus, with the help of the surface sound-absorbing component 70, noise can be absorbed and eliminated more efficiently, improving the noise reduction effect.

[0058] In some embodiments, at least a portion of the edges of the guide member 30 are configured with a rounded transition.

[0059] Thus, the smooth design of the air guide 30 can effectively reduce the air resistance of the ventilation airflow and ensure normal heat dissipation.

[0060] In some embodiments, the ventilation structure 100 includes at least three sets of flow guiding components 3, all of which are arranged sequentially at intervals along the ventilation direction, and the flow guiding elements 30 of two adjacent sets of flow guiding components 3 are staggered.

[0061] Understandably, the longitudinal directions of all the flow guides 30 (corresponding to the directions perpendicular to the paper in Figure 5) are parallel to each other, and the ventilation direction, the first direction, and the longitudinal direction of the flow guides 30 intersect each other in pairs. For ease of understanding, the following embodiments are illustrated by taking the ventilation direction, the first direction, and the longitudinal direction of the flow guides 30 as examples where they are perpendicular to each other in pairs.

[0062] The staggered arrangement of the guide elements 30 in two adjacent groups of flow guiding components 3 means that the guide elements 30 in two adjacent groups of flow guiding components 3 are alternately arranged in the first direction. Overall, each group of flow guiding components 3 forms a layer of noise reduction structure, and all the guide elements 30 are staggered to form a multi-layer noise reduction structure.

[0063] In this way, all the flow guides 30 are arranged in a staggered manner to form a multi-layer noise reduction structure. During the propagation process, the noise is reduced by multiple layers and can be emitted between different layers of flow guide components 3, and then consumed and absorbed.

[0064] In some embodiments, the mounting body 10 includes a top plate 11 and a bottom plate 13 extending along a first direction, all flow guiding components 3 are located between the top plate 11 and the bottom plate 13, and the opposite ends of each flow guiding component 30 are connected to the top plate 11 and the bottom plate 13 respectively.

[0065] In other words, the arrangement direction of the guide members 30 in each group of guide components 3 is consistent with the extension direction of the top plate 11 and the bottom plate 13. The top plate 11 and the bottom plate 13 are located at opposite ends of the guide members 30 in the longitudinal direction. The guide members 30 can be configured to be arranged along the height direction, with the top plate 11 and the bottom plate 13 located on the upper and lower sides, respectively.

[0066] In this way, all the flow guides 30 can be stably fixed by the top plate 11 and the bottom plate 13, and finally stably installed at the ventilation opening 210 of the energy storage cabinet 200 by the mounting body 10.

[0067] Furthermore, the mounting body 10 also includes two side plates 15, which together with the top plate 11 and the bottom plate 13 form a frame, and the frame has flanges 17 around its perimeter.

[0068] Thus, the mounting body 10 has a stable structure, and as a frame, its internal space is just right for arranging the airflow guiding component 3. In addition, the ventilation structure 100 can be fixed to the ventilation opening 210 by means of screw connection, welding, snap-fit, adhesive, etc. through the flange 17, and this fixing method can be detachable.

[0069] In one specific embodiment, the mounting body 10 is generally a rectangular frame formed by connecting a top plate 11, a side plate 15, a bottom plate 13, and another side plate 15 end to end.

[0070] Understandably, in other embodiments, the mounting body 10 may also be a circular frame, a triangular frame, etc., as long as it can adapt to the shape of the vent 210, and no specific limitation is made here.

[0071] In some embodiments, at least a portion of the flow guiding assembly 3 further includes an arc-shaped flow guiding element 50, which is disposed on the side plate 15. The longitudinal direction of the arc-shaped flow guiding element 50 is parallel to the longitudinal direction of the other flow guiding elements 30.

[0072] Understandably, a noise-absorbing element 70 may also be provided on the arc-shaped flow guide 50. Similarly, the noise-absorbing element 70 of the arc-shaped flow guide 50 is also provided on the side facing the noise source.

[0073] In some embodiments, at least some of the guide elements 30 in each group of guide components 3 are spaced apart from each other. Projected along the ventilation direction onto a plane perpendicular to the ventilation direction, all the guide elements 30 collectively cover the vent 210. It can be understood that all the guide elements 30 here may include guide elements 30 and arc-shaped guide elements 50.

[0074] In other words, light cannot pass through one side of the ventilation structure 100 to the other side along the ventilation direction.

[0075] Understandably, all the air guides 30 can be spaced apart from each other, and through a staggered arrangement, while being spaced apart from each other, their projections on a plane perpendicular to the ventilation direction overlap and cover the entire ventilation opening 210. Specifically, all the air guides 30 can be configured so that their projections in any direction all cover the ventilation opening 210.

[0076] Thus, from the perspective of ventilation direction, all the air guides 30 together cover the vent 210, which increases the difficulty of noise penetration, causing noise to reflect between different air guides 30, thereby enhancing the noise reduction effect. In addition, from the perspective of ventilation direction, all the air guides 30 together covering the vent 210 also improves its waterproof performance, meeting the waterproof requirements of the equipment.

[0077] In one specific embodiment, the ventilation structure 100 includes three sets of flow guiding components 3, namely a first row, a second row, and a third row arranged sequentially in the ventilation direction. The first and third rows of flow guiding components 3 overlap in projection onto a plane perpendicular to the ventilation direction, and each flow guiding element 30 in the second row is located between two flow guiding elements 30 in the first or third row. In a first direction, the projections of the flow guiding elements 30 in the first or third row alternate with those of the flow guiding elements 30 in the second row. Two arc-shaped flow guiding elements 50 are arranged side-by-side with the flow guiding elements 30 in the second row, and their projections onto a plane perpendicular to the ventilation direction are respectively connected to the flow guiding elements 30 in the first or third row.

[0078] In some embodiments, the guide member 30 forms a cavity 31 on one side (i.e., the leeward side) in the ventilation direction and a convex surface on the opposite side (i.e., the windward side) in the ventilation direction, and the width of the convex surface in at least part of the first direction gradually narrows in the direction away from the concave surface.

[0079] Understandably, the leeward side can be recessed inward along the ventilation direction to form a concave cavity 31, and the windward side can be convex outward along the ventilation direction to form a convex surface, and the cavity gradually narrows in the direction away from the leeward side.

[0080] Thus, at the windward angle, the two sides of the guide 30 can exhibit significant differences in the ventilation direction, with the drag coefficient on the leeward side being significantly higher than that on the windward side. Furthermore, when the leeward side faces the noise source, the cavity 31 can absorb noise more effectively.

[0081] In some other embodiments, the leeward side can also be constructed as a plane perpendicular to the ventilation direction, as long as the resulting drag coefficient is greater than that of the windward side, and no specific limitation is made here.

[0082] In some embodiments, the longitudinal direction of the guide member 30 intersects the ventilation direction, the cross-section of the guide member 30 perpendicular to its longitudinal direction is a Y-shaped structure, and the vertical direction of the Y-shaped structure is parallel to the ventilation direction.

[0083] The vertical direction of the Y-shaped structure corresponds to the ventilation direction. Its upper side is concave, corresponding to the leeward side with the cavity 31, while its left and right sides and bottom side correspond to the windward side. The left and right sides of the Y-shaped structure can be formed into arcs, gradually widening in the ventilation direction. The upper edge of the Y-shaped structure extends along the ventilation direction after an arc transition to form a guide section 35, thereby reducing airflow resistance.

[0084] Thus, the opening of the concave cavity 31 of the air guide 30 corresponds to the concave fork of the Y-shaped structure, resulting in a large drag coefficient and good noise reduction performance. Meanwhile, the windward side of the air guide 30 mainly corresponds to the left and right sides of the Y-shaped structure; the gradually widening design in the ventilation direction effectively reduces the drag coefficient and facilitates ventilation and heat dissipation.

[0085] The ventilation structure 100 described above features a multi-layered noise reduction structure formed by the orderly staggered arrangement of airflow guides 30 and arc-shaped airflow guides 50. The surfaces of the airflow guides 30 and arc-shaped airflow guides 50 facing the internal noise source are also covered with sound-absorbing components 70, and gaps are formed between all the airflow guides 30 to maintain the air permeability of the ventilation opening 210. Furthermore, the smooth design of the airflow guides 30 effectively reduces wind resistance. Thus, the ventilation structure 100 allows for the passage of cooling airflow to meet heat dissipation requirements. Simultaneously, when noise is transmitted outward within the ventilation opening 210, it is blocked by the multi-layered noise reduction structure and reflected between different airflow guides 30, gradually being absorbed and eliminated, achieving both heat dissipation and noise reduction.

[0086] In the ventilation structure 100 located at the air inlet 211, one side of the inner guide member 30 with a cavity 31 faces inwards from the air inlet 211, and the other side faces outwards from the air inlet 211. During operation, the cooling airflow flows from the outside to the inside, while noise propagates from the inside to the outside; the two paths are opposite. The cooling airflow blows towards the windward side with the guiding function, where resistance is low, and under the guidance of the guide member 30, it blows into the air inlet 211 for heat dissipation. Meanwhile, during noise propagation, it is absorbed and eliminated by the cavity 31 of the guide member 30 and the sound-absorbing member 70 attached to the cavity wall of the cavity 31, and is gradually reduced by multiple stages of noise reduction from the multi-layered noise reduction structure, thereby achieving the purpose of noise reduction.

[0087] For the ventilation structure 100 located at the air outlet 212, one side of the cavity 31 formed by the inner guide member 30 faces outward from the air outlet 212, and the other side faces inward from the air outlet 212. During operation, the heat dissipation airflow flows from the inside to the outside after heat exchange, blowing towards the windward side with the guiding function, encountering less resistance, and is blown out of the air outlet 212 under the guidance of the guide member 30. During the propagation process, noise is absorbed and eliminated by the interaction between the surfaces of the guide member 30 and by the sound-absorbing member 70 attached to the surface of the guide member 30, and is gradually reduced by the multi-stage noise reduction structure, thereby achieving the purpose of noise reduction.

[0088] This application also provides an energy storage cabinet 200, which includes a cabinet body 21 and the aforementioned ventilation structure 100.

[0089] Furthermore, at least one of the cabinet door 213, top plate 11 and bottom plate 13 of the cabinet body 21 has a ventilation opening 210, and at least some of the ventilation openings 210 are provided with a ventilation structure 100.

[0090] In this way, the vent 210 and the ventilation structure 100 installed at the vent 210 can facilitate ventilation without taking up too much internal space of the cabinet 21.

[0091] Furthermore, a vent 210 is formed on the cabinet door 213, which serves as an air inlet 211. The air inlet 211 is equipped with a ventilation structure 100, and the opening of the cavity 31 of the air guide 30 faces the interior of the cabinet body 21. A sound-absorbing component 70 is applied to the cavity wall of the cavity 31.

[0092] Understandably, the ventilation structure 100 of the air inlet 211 can be installed on the inside of the cabinet door 213, and the air outlet 212 can be formed on the top of the cabinet body 21. The ventilation structure 100 of the air outlet 212 can be installed on the top of the cabinet body 21.

[0093] In this way, the opening angle of the door will not be affected, nor will the overall appearance of the energy storage cabinet 200 be affected.

[0094] Please refer to Figures 9 to 16. This application also provides an energy storage system 400, including the ventilation structure 100 or the energy storage cabinet 200 described above.

[0095] In addition, to achieve its normal function, the energy storage system 400 also includes at least one of a battery system, a liquid cooling unit 412, and an electrical system. The energy storage system 400 also includes a housing 410, which forms a liquid cooling compartment 411, a battery compartment, and an electrical compartment. The liquid cooling unit 412 is installed in the liquid cooling compartment 411, the battery system is installed in the battery compartment, and the electrical system is installed in the electrical compartment. The housing 410 can be served by the aforementioned energy storage cabinet 200.

[0096] During operation, the equipment in each compartment of the energy storage system 400 generates heat and a certain degree of noise. When outdoor air enters the compartment to dissipate heat from the equipment, the noise may spread to the outside through the air inlet 211, air outlet 212 and other ventilation openings 210, affecting the outside environment.

[0097] Taking the liquid-cooled chamber 411 as an example, the chamber's protection level is designed to be IP20. To meet the heat dissipation requirements of the liquid-cooled chamber 411, a front-inlet and top-outlet airflow design is adopted. Ventilation structures 100 are installed at both the air inlet 211 and the air outlet 212 of the liquid-cooled chamber 411, which can not only meet the requirements of ventilation circulation and equipment heat dissipation and cooling, but also reduce the noise transmitted from the chamber to the outside, thereby achieving the noise reduction function of the entire energy storage system 400.
