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.

[0043] In addition, if the term "and / or" appears, "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated with each other are in an "or" relationship. If the terms "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0047] Referring to Figures 1 to 8 , a ventilation structure 100 provided in one embodiment of the present application includes a mounting body 10 and at least one set of flow guide assemblies 3. The mounting body 10 is configured to be assembled and connected to the vent 210 of the energy storage cabinet 200. All flow guide assemblies 3 are connected to the mounting body 10. Each set of flow guide assemblies 3 includes a plurality of flow guide members 30 arranged along a first direction (the X direction as shown in Figure 5 ), which intersects the ventilation direction of the energy storage cabinet 200 (the Y direction as shown in Figure 5 ). The flow guide members 30 have a concave cavity 31 with an opening formed on one side facing the ventilation direction.

[0048] It is understood that the ventilation structure 100 is installed at the vent 210 via the mounting body 10. After installation, the ventilation structure 100 blocks the vent 210 or is partially embedded in the vent 210, so that ventilation at the vent 210 is carried out through the ventilation structure 100. All the guide members 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 guide assembly 3.

[0049] It is understandable that the vent 210 of the energy storage cabinet 200 can be either an air inlet 211 or an air outlet 212. To achieve the basic ventilation function, the air guide assembly 3 does not completely block the vent 210, but only guides the airflow flowing through the vent 210 or changes its flow direction and state.

[0050] Specifically, each guide member 30 has a windward side and a leeward side on either side in the ventilation direction. The windward side of the guide member 30 has a diversion function, and the wind resistance of the guide member 30 on the windward side is lower, allowing it to guide the airflow. On the leeward side, however, the guide member 30 forms the aforementioned cavity 31, which has greater wind resistance and can absorb and eliminate noise. In other words, the drag coefficients of the guide member 30 on the windward and leeward sides are configured to be different. Under the same conditions, the wind resistance generated by airflow blowing toward the windward and leeward sides of the guide member 30 is different.

[0051] Among them, 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 more than 0.5, and may specifically be 0.5, 0.4, 0.3, 0.2 or 0.1, etc., and no specific limitation is given here.

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

[0053] The ventilation structure 100 is attached to the vent 210. Airflow passing through the vent 210 also flows through the ventilation structure 100. As noise propagates outward through the ventilation structure 100, it collides and dissipates between the guide members 30, achieving a noise reduction effect. When the vent 210 is an air inlet 211, the ventilation structure 100 can be strategically positioned so that the cavity 31 of the guide member 30 faces the interior of the energy storage cabinet 200, that is, toward the noise source. Airflow flowing in from the outside is properly guided by the guide member 30 and smoothly enters the interior, while noise propagating from the inside out is absorbed and dissipated by the cavity 31 of the guide member 30. In this way, the ventilation structure 100 integrates noise reduction functionality, providing both air guidance and noise reduction. This makes the ventilation structure 100 simple and highly integrated, making it easy to attach to the vent 210, ensuring ventilation and heat dissipation while suppressing noise transmission.

[0054] In some embodiments, the ventilation structure 100 further includes a silencer 70 (as shown in FIG. 12 and FIG. 15 ). The silencer 70 is disposed on a side of the guide member 30 facing the interior of the energy storage cabinet 200 in the ventilation direction.

[0055] The silencer 70 may be made of, but is not limited to, silencer cotton, sponge, velvet, or the like. The flow guide 30 is covered with the silencer 70 on the side facing the interior of the energy storage cabinet 200 , that is, the side facing the noise source, so that when the noise propagates to the surface of the flow guide 30 , it is silenced by the silencer 70 .

[0056] It is understood that for the ventilation structure 100 provided at the air inlet 211, it can be configured so that the cavity 31 of the air guide 30 opens toward the interior of the energy storage cabinet 200, so that the silencer 70 is disposed on the wall of the cavity 31. For the ventilation structure 100 provided at the air outlet 212, it can be configured so that the cavity 31 of the air guide 30 opens away from the interior of the energy storage cabinet 200, so that the silencer 70 is disposed on the surface facing the interior of the energy storage cabinet 200.

[0057] In this way, with the help of the surface silencer 70, noise can be absorbed and eliminated more efficiently, thereby improving the noise reduction effect.

[0058] In some embodiments, at least a portion of the edge of the flow guide 30 is configured as an arc transition.

[0059] In this way, the smooth design of the guide member 30 can effectively reduce the wind resistance of the ventilation airflow and ensure normal heat dissipation.

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

[0061] It can be understood that the longitudinal directions of all the guide members 30 (corresponding to the direction perpendicular to the paper in Figure 5) are parallel to each other, and the ventilation direction, the first direction and the longitudinal directions of the guide members 30 intersect with each other. For ease of understanding, the following embodiments are explained by taking the ventilation direction, the first direction and the longitudinal directions of the guide members 30 as an example in which they are perpendicular to each other.

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

[0063] In this way, all the guide members 30 are arranged and combined in a staggered manner to form a multi-layer noise reduction structure. During the propagation process, the noise passes through the multi-layer noise reduction and can be emitted between the guide components 3 on different layers to be 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 the guide components 3 are located between the top plate 11 and the bottom plate 13, and opposite ends of each guide member 30 are connected to the top plate 11 and the bottom plate 13 respectively.

[0065] In other words, the arrangement direction of the flow guide members 30 of each flow guide assembly 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 respectively located at opposite ends of the flow guide members 30 in the longitudinal direction. The flow guide members 30 can be configured to be arranged along the height direction, with the top plate 11 and the bottom plate 13 located at 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 vent 210 of the energy storage cabinet 200 through the installation body 10 .

[0067] Furthermore, the mounting body 10 further includes two side panels 15 . The two side panels 15 , the top panel 11 , and the bottom panel 13 together form a frame, and flanges 17 are formed around the frame.

[0068] Thus, the mounting body 10 has a stable structure and serves as a frame, and its internal space is just right for arranging the guide assembly 3. In addition, the ventilation structure 100 can be fixed to the ventilation opening 210 by screw connection, welding, clamping, bonding, etc. through the flange 17, and the fixing method can be detachable.

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

[0070] It is understandable that 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 part of the flow guide assembly 3 further includes an arcuate flow guide 50, which is provided on the side plate 15. The longitudinal direction of the arcuate flow guide 50 is parallel to the longitudinal direction of the other flow guides 30.

[0072] It is understandable that the arc-shaped flow guide 50 may also be covered with a silencer 70. Similarly, the silencer 70 of the arc-shaped flow guide 50 is also covered on the side thereof facing the noise source.

[0073] In some embodiments, at least some of the guide members 30 of each group of guide assemblies 3 are spaced apart from each other. Projected along the ventilation direction onto a plane perpendicular to the ventilation direction, all of the guide members 30 collectively cover the ventilation opening 210. It is understood that all of the guide members 30 herein may include the guide members 30 and the curved guide members 50.

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

[0075] It is understood that all the air guides 30 can be spaced apart from each other and arranged in a staggered manner so that, while being spaced apart from each other, their projections along the ventilation direction on a plane perpendicular to the ventilation direction overlap and cover the entire vent 210. Specifically, all the air guides 30 can be configured so that their projections along any direction jointly cover the vent 210.

[0076] In this way, all the guides 30 cover the vents 210 in the ventilation direction, which makes it more difficult for noise to penetrate and reflects noise between the different guides 30, thereby enhancing the noise reduction effect. In addition, all the guides 30 covering the vents 210 in the ventilation direction can also improve its waterproof performance, meeting the waterproof requirements of the equipment.

[0077] In one embodiment, the ventilation structure 100 includes three groups of guide assemblies 3, namely, the first row, the second row, and the third row, arranged sequentially in the ventilation direction. The guide assemblies 3 in the first and third rows overlap, as projected onto a plane perpendicular to the ventilation direction. Each guide member 30 in the second row of guide assemblies 3 is located between two guide members 30 in the first or third row of guide assemblies 3. In the first direction, the guide members 30 in the first or third row of guide assemblies 3 are alternately connected to the projections of the guide members 30 in the second row. Two curved guide members 50 are arranged side by side with the guide members 30 in the second row of guide assemblies 3, and are connected to the guide members 30 in the first or third row of guide assemblies 3, respectively, as projected onto a plane perpendicular to the ventilation direction.

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

[0079] It can be understood that the leeward side can be concave inwardly along the ventilation direction to form a concave cavity 31, and the windward side can be convex outwardly along the ventilation direction to form a convex surface, and is gradually narrowed in the direction away from the leeward side.

[0080] Thus, at the windward angle, the two sides of the deflector 30 in the ventilation direction can show a significant difference, and the drag coefficient on the leeward side can be significantly higher than that on the windward side. In addition, when the leeward side faces the noise source, the cavity 31 can better absorb noise.

[0081] In some other embodiments, the leeward side may also be constructed as a plane perpendicular to the ventilation direction, etc., 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 with the ventilation direction, the cross section of the guide member 30 perpendicular to its longitudinal direction is a Y-shaped structure, and the up and down directions of the Y-shaped structure are parallel to the ventilation direction.

[0083] The Y-shaped structure's top and bottom correspond 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 curved, gradually widening in the ventilation direction. The upper edge of the Y-shaped structure transitions into an arc, extending in the ventilation direction to form a guide section 35, thereby reducing wind resistance.

[0084] Thus, the opening of the concave cavity 31 of the deflector 30 corresponds to the fork of the Y-shaped structure, resulting in a larger drag coefficient and excellent sound-absorbing performance. Meanwhile, the windward side of the deflector 30 primarily corresponds to the left and right sides of the Y-shaped structure. The gradually widening configuration in the ventilation direction effectively reduces the drag coefficient and facilitates ventilation and heat dissipation.

[0085] The ventilation structure 100 described above has its flow guides 30 and curved flow guides 50 arranged in an orderly staggered arrangement to form a multi-layer noise reduction structure. The flow guides 30 and curved flow guides 50 are also covered with silencers 70 on the surface facing the internal noise source, and gaps are formed between all the flow guides 30 to retain the air permeability of the vents 210. In addition, the smooth design of the flow guides 30 can effectively reduce wind resistance. In this way, the ventilation structure 100 can allow heat dissipation airflow to pass through to meet heat dissipation requirements. At the same time, when noise is transmitted from the vents 210 to the outside, it is blocked by the multi-layer noise reduction structure and can be reflected between different flow guides 30 and gradually absorbed and eliminated, achieving the effect of noise reduction while meeting heat dissipation requirements.

[0086] Specifically, for the ventilation structure 100 located at the air inlet 211, the inner guide member 30 has a cavity 31 with one side facing the inside of the air inlet 211 and the other side facing the outside of the air inlet 211. During operation, the heat dissipating airflow flows from the outside to the inside, while the noise propagates from the inside to the outside, with the two paths being opposite. The heat dissipating airflow blows toward the windward side, which has a guiding effect, where resistance is less. Guided by the guide member 30, it blows into the air inlet 211 to dissipate heat. During the propagation process, the noise is absorbed and eliminated by the cavity 31 of the guide member 30 and the silencer 70 attached to the wall of the cavity 31. Furthermore, the noise is gradually reduced by the multi-stage noise reduction of the multi-layer noise reduction structure, thereby achieving the purpose of noise reduction.

[0087] In the ventilation structure 100 located at the air outlet 212, the concave cavity 31 formed by the internal air guide 30 faces outward from the air outlet 212 on one side and inward from the other. During operation, the heat dissipating airflow, after heat exchange, flows from the inside outward, toward the windward side of the air guide, encountering less resistance. Guided by the air guide 30, it is blown out of the air outlet 212. During the propagation process, the noise is absorbed and dissipated between the surfaces of the air guide 30 and by the muffler 70 attached to the surface of the air guide 30. Furthermore, the noise is gradually reduced by the multi-stage noise reduction structure, thereby achieving the desired noise reduction effect.

[0088] The present application also provides an energy storage cabinet 200 , which includes a cabinet body 21 and the above-mentioned ventilation structure 100 .

[0089] Furthermore, at least one of the cabinet door 213 , the top plate 11 , and the bottom plate 13 of the cabinet body 21 is formed with a ventilation opening 210 , and at least a portion of the ventilation opening 210 is 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 occupying too much internal space of the cabinet 21 .

[0091] Furthermore, the cabinet door 213 is formed with a vent 210 as an air inlet 211. The air inlet 211 is provided with a ventilation structure 100. The opening of the cavity 31 of the guide member 30 faces the interior of the cabinet 21. The muffler 70 is covered on the wall of the cavity 31.

[0092] It can be understood that the ventilation structure 100 of the air inlet 211 can be installed on the inner side of the cabinet door 213, the air outlet 212 can be formed on the top of the cabinet body 21, and the ventilation structure 100 of the air outlet 212 can be installed on the top of the cabinet body 21.

[0093] In this way, neither the opening and closing angle of the door nor the overall appearance of the energy storage cabinet 200 is affected.

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

[0095] To ensure proper function, energy storage system 400 also includes at least one of a battery system, a liquid cooling unit 412, and an electrical system. Energy storage system 400 also includes a cabin 410, which comprises a liquid cooling compartment 411, a battery compartment, and an electrical compartment. Liquid cooling unit 412 is installed within liquid cooling compartment 411, the battery system is installed within the battery compartment, and the electrical system is installed within the electrical compartment. Cabin 410 can be implemented using the aforementioned energy storage cabinet 200.

[0096] The equipment in each compartment of the energy storage system 400 generates heat during operation, and also generates a certain degree of noise. When outdoor air enters and exits the compartment to dissipate heat for the equipment, the noise may be transmitted to the outside through the vents 210 such as the air inlet 211 and the air outlet 212, thereby affecting the outside world.

[0097] Taking liquid cooling chamber 411 as an example, the chamber's protection level is designed to IP20. To meet the cooling requirements of liquid cooling chamber 411, air intake is from the front and air outlet is from the top. Ventilation structures 100 are installed at both the air inlet 211 and the air outlet 212 of liquid cooling chamber 411. This not only ensures ventilation circulation and equipment heat dissipation and cooling, but also reduces noise transmitted from the chamber to the outside, thereby achieving noise reduction for the entire energy storage system 400.

[0098] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
