These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0032] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0033] First, the terms involved in this application are explained:

[0034] Energy storage container: Energy storage container is a modular energy storage solution, which adopts standard container design, is easy to transport and install, and is widely used in renewable energy integration, grid regulation and backup power supply. It integrates the battery management system (full name: Battery Management System, English abbreviation: BMS), inverter, cooling system and safety monitoring system, and can flexibly adjust capacity and configuration to meet energy management needs of different scales. Energy storage container improves the stability and efficiency of the power system by storing and releasing electric energy, and is an indispensable part of modern energy system.

[0035] Return air short circuit: refers to the cooling or ventilation system, in which the cooling air fails to circulate effectively to all components that need to be cooled, and an abnormal airflow circulation is formed between the air inlet and the air outlet. This situation may cause the temperature in some areas to be too high, affecting the performance and life of batteries or other electronic devices, and even causing safety hazards.

[0036] Butterfly Screw: Also known as a butterfly bolt or thumb screw, it is a specially designed screw with wing-like protrusions on either side of the head. This design allows the user to tighten or loosen the screw directly by hand without the use of tools such as screwdrivers or wrenches. Butterfly screws are often used in situations where frequent adjustments or quick assembly and disassembly are required, such as furniture, equipment housings, or other applications that require manual operation. Due to their easy-to-operate characteristics, they are particularly useful in situations where quick assembly and disassembly are required.

[0037] In the prior art, the cooling unit is often placed directly in the energy storage container, and the air outlet of the cooling unit is set at the air outlet of the energy storage container to discharge hot air to the outside. However, in the energy storage system, in order to improve land utilization and reduce construction costs, the energy storage containers are often arranged too compactly, resulting in obstructed air circulation, the hot air discharged by the cooling unit cannot be effectively discharged, the hot air is re-inhaled, and the cold air is difficult to smoothly enter the equipment, and even the return air short circuit phenomenon occurs. The return air short circuit phenomenon further weakens the cooling effect, making the heat dissipation efficiency of the energy storage system low.

[0038] When operating at high load, the energy storage system generates a large amount of heat. If the cooling unit cannot remove the heat in time, the battery cluster temperature will be too high, which can easily lead to thermal runaway, causing fire or damage to equipment. Long-term operation in a high temperature environment will also accelerate the performance degradation of the battery cluster, significantly reducing the safety and service life of the energy storage system.

[0039] The present application provides an air duct, an energy storage container, and an energy storage system. The air duct is installed at the air outlet of the energy storage container to guide the hot air discharged to the outside by the energy storage container. Specifically, the air duct body has an air duct inlet and an air duct outlet. The air duct inlet is connected to the air outlet of the energy storage container, so that the hot air discharged from the energy storage container enters the air duct through the air duct inlet and escapes toward the upper end of the energy storage container through the air duct outlet. The hot air is guided by the air duct to prevent the hot air from being re-inhaled into the system, thereby achieving the effect of improving the heat dissipation efficiency.

[0040] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0041] In some embodiments of this application, see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, Figure 1 This is a schematic diagram of the structure of the air duct. Figure 2 This is a schematic diagram of the wind duct structure when viewed from above. Figure 3 This is a side view of the air duct structure. Figure 4 This is a schematic diagram of the installation of the air duct and energy storage container.

[0042] The air duct is applied to the energy storage container 200, and the air duct includes an air duct body 100, and the air duct body 100 has an air duct air inlet 110 and an air duct air outlet 120, and the air duct air inlet 110 is connected to the air outlet of the energy storage container 200, so that the hot air discharged from the energy storage container 200 enters the air duct body 100 through the air duct air inlet 110, and escapes toward the upper end of the energy storage container 200 through the air duct air outlet 120.

[0043] Exemplarily, the cooling unit is arranged in the energy storage container 200, and the energy storage container 200 has an air outlet of the energy storage container 200 and an air inlet of the energy storage container 200. The air outlet of the cooling unit is arranged adjacent to the air outlet of the energy storage container 200, and the air outlet of the cooling unit discharges hot air to the outside through the air outlet of the energy storage container 200. The air duct is externally arranged on the energy storage container 200, and the air duct includes an air duct body 100, and the air duct body 100 has an air duct outlet 120 and an air duct inlet 110, and the air duct inlet 110 is connected to the air outlet of the energy storage container 200, and the hot air enters the air duct body 100 through the air duct inlet 110, and escapes toward the upper end of the energy storage container 200 through the air duct outlet 120.

[0044] Installing air ducts on the energy storage container 200 can effectively guide the flow direction of hot air and avoid airflow short-circuiting caused by the arrangement of the energy storage container 200. This design prevents airflow interference between the cooling unit and other equipment, thereby avoiding the problem of temperature rise of the cooling unit and frequent start and stop of the compressor. By optimizing the airflow path, the cooling efficiency is improved, the risk of overheating of the energy storage system is reduced, and the safe operation of the system is ensured.

[0045] In some embodiments of the present application, the air duct includes an air guide plate 130 and two connecting plates 140 .

[0046] One end of the air guide plate 130 contacts the energy storage container 200, and the other end extends to the outside of the energy storage container 200, and forms an air guide gap between the air guide plate 130 and the energy storage container 200, and the air guide gap extends along the height direction of the energy storage container 200. Two connecting plates 140 are disposed on opposite sides of the air guide plate 130, and the sides of the two connecting plates 140 facing away from the air guide plate 130 are connected to the energy storage container 200 to close the two sides of the air guide gap, thereby forming an air duct cavity.

[0047] One end of the air duct cavity facing the top of the energy storage container 200 is the air duct outlet 120 , and the side of the air duct cavity adjacent to the energy storage container 200 is the air duct inlet 110 .

[0048] It should be noted that the present application does not limit the shape of the air deflector 130. For example, the air deflector 130 may be an arc-shaped plate or an L-shaped plate. When the air deflector 130 is an arc-shaped plate, the arc-shaped plate is bent toward the energy storage container 200, one end of the arc-shaped plate is in contact with the energy storage container 200, and the other end extends to the outside of the energy storage container 200, and there is an air guide gap between the energy storage container 200. The shapes of the two connecting plates 140 correspond to the arc-shaped plates, and the two connecting plates 140 are arranged on both sides of the arc-shaped plates. The two connecting plates 140 are connected to the energy storage container 200 on the side away from the arc-shaped plates to close the air guide gap, thereby forming an air duct cavity.

[0049] The wind deflector 130 may also be an L-shaped plate, which includes a bottom plate and a vertical plate. One end of the bottom plate contacts the energy storage container 200, and the other end is connected to the vertical plate. The vertical plate extends to the outside of the energy storage container 200, and there is a wind guide gap between the vertical plate and the energy storage container 200. The shapes of the two connecting plates 140 correspond to the L-shaped plate. The two connecting plates 140 are arranged on both sides of the L-shaped plate. The two connecting plates 140 are connected to the energy storage container 200 on the side away from the L-shaped plate to close the wind guide gap, thereby forming an air duct cavity.

[0050] Exemplarily, the air duct and the energy storage container 200 may be formed as one piece, or may be separately provided, for example, by being installed and fixed by welding, riveting, and clamping.

[0053] It should be noted that the present application does not limit the materials of the connecting plate 140 and the air guide plate 130. For example, the connecting plate 140 and the air guide plate 130 can be made of any material such as plastic, steel, etc.

[0054] Furthermore, the connecting plate 140 and the air guide plate 130 may be made of different materials or the same material. Preferably, the connecting plate 140 and the air guide plate 130 are made of the same material. For example, in order to increase the service life of the air duct, the connecting plate 140 and the air guide plate 130 may be made of 45 steel.

[0055] The connecting plate 140 and the air guide plate 130 are made of the same material, so they have a consistent thermal expansion coefficient and similar thermal expansion and contraction behavior when the temperature changes, which helps to reduce deformation or damage caused by thermal stress. It can also simplify the manufacturing and installation process without considering the compatibility of different materials. At the same time, using the same material can usually reduce production costs. Using the same material can also ensure that the air duct is consistent in appearance and more beautiful.

[0056] In some embodiments of the present application, the air duct further includes a first mounting beam 150 and a second mounting beam 160 .

[0057] The opposite sides of the first mounting beam 150 are respectively connected to the wind deflector 130 and the energy storage container 200, and the two ends of the first mounting beam 150 are correspondingly connected to the two connecting plates 140. The two ends of the second mounting beam 160 are respectively connected to one end of the two connecting plates 140 away from the first mounting beam 150.

[0058] The first mounting beam 150 , the second mounting beam 160 , the air guide plate 130 and the two connecting plates 140 together form the air duct inlet 110 , and the second mounting beam 160 , the air guide plate 130 and the two connecting plates 140 together form the air duct outlet 120 .

[0059] Exemplarily, the opposite sides of the first mounting beam 150 are respectively connected to the wind deflector 130 and the energy storage container 200. Specifically, the opposite sides of the first mounting beam 150 can be respectively connected to the wind deflector 130 and the energy storage container 200 by welding; the opposite sides of the first mounting beam 150 can also have mounting holes, and the side where the wind deflector 130 is connected to the first mounting beam 150 can be provided with a flange, and the flange is correspondingly provided with a mounting hole. The wind deflector 130 is connected to the first mounting beam 150 by bolts passing through the mounting holes, and the energy storage container The cabinet door of 200 is also correspondingly provided with mounting holes, and screws are also passed through the mounting holes in sequence, and the energy storage container 200 is connected to the side of the first mounting beam 150 that is away from the connection with the air guide plate 130; further, the first mounting beam 150 and the air guide plate 130 can be integrally formed by extrusion or the like, and the side of the first mounting beam 150 that is away from the connection with the air guide plate 130 is provided with mounting holes, and the cabinet door of the energy storage container 200 is correspondingly provided with mounting holes, and the first mounting beam 150 is connected to the energy storage container 200 by screws passing through the mounting holes in sequence.

[0060] Furthermore, two ends of the first mounting beam 150 are connected to the two connecting plates 140 respectively, and may be integrally formed, welded, or riveted.

[0061] The air duct and the energy storage container 200 are separately arranged by the first mounting beam 150 and the second mounting beam 160. Preferably, the air duct and the energy storage container 200 are detachably connected by riveting. The air duct and the energy storage container 200 can be arranged according to the specific space and function, which makes the design and installation process more flexible; at the same time, it is easier to transport and install, reducing the difficulty and cost of component transportation, and making maintenance and overhaul more convenient. If the system needs to be upgraded, it is easier to replace or add components without changing the entire system, thereby reducing costs.

[0062] In some embodiments of the present application, a drainage hole 131 communicating with the air duct cavity is provided at one end of the air guide plate 130 facing away from the air duct outlet 120 .

[0063] Exemplarily, a plurality of drainage holes 131 may be provided. Six drainage holes 131 may be provided at one end of the air guide plate 130 away from the air duct outlet 120. The six drainage holes 131 are divided into two rows, with three drainage holes 131 in each row. The drainage holes 131 are through holes connected to the air duct cavity, so that the accumulated water in the air duct can be quickly discharged, thereby preventing the accumulated water in the air duct from flowing back into the energy storage container 200 through the air duct inlet 110, affecting the normal operation of the energy storage system and causing safety problems.

[0064] It should be noted that the present application does not impose any specific limitation on the number and arrangement of the drainage holes 131 .

[0065] In some embodiments of the present application, a cleaning port 132 connected to the air duct cavity is provided at one end of the air guide plate 130 facing away from the air duct outlet 120; a shielding plate 133 is detachably provided on the air guide plate 130 or the connecting plate 140, and the shielding plate 133 covers the cleaning port 132.

[0066] Exemplarily, a cleaning port 132 connected to the air duct cavity is provided at one end of the air guide plate 130 away from the air duct outlet 120, and the cleaning port 132 is used to clean debris in the air duct, for example: fallen leaves, garbage and other debris that fall into the air duct due to wind and rain.

[0067] In order to prevent the cleaning port 132 from affecting the guiding effect of the wind duct on the hot air at the air outlet of the energy storage container 200, a shielding plate 133 is provided to cover the cleaning port 132. The shielding plate 133 can be detachably connected to the air guide plate 130, and can also be detachably connected to the connecting plate 140. Exemplarily, one end of the shielding plate 133 can be rotatably connected to a connecting plate 140 by a hinge, and the end of the shielding plate 133 that is away from the connecting plate 140 connected by the hinge can be detachably connected to another connecting plate 140 arranged opposite. For example, a card slot is provided on the connecting plate 140 that is detachably connected to the shielding plate 133, and a buckle is provided at the end of the shielding plate 133 that is away from the connecting plate 140 connected by the hinge. When in use, the opening and closing state of the shielding plate 133 can be controlled by the buckle and the card slot; the shielding plate 133 can also have a mounting hole, and the air guide plates 130 around the cleaning port 132 are correspondingly provided with mounting holes, and bolts pass through the mounting holes. The shielding plate 133 is connected to the air guide plate 130 by bolts, and the cover is set on the cleaning port 132 to achieve a detachable connection.

[0068] In some embodiments of the present application, the drainage hole 131 is disposed on the shielding plate 133 .

[0069] For example, six drainage holes 131 are provided on the shielding plate 133, and the drainage holes 131 are divided into two rows, with three drainage holes 131 in each row, and the drainage holes 131 are through holes, which are connected to the air duct cavity. When the drainage holes 131 are blocked by dust or other debris, the shielding plate 133 can be removed to clear the drainage holes 131, making maintenance easier.

[0070] In some embodiments of the present application, a first supporting portion 141 is provided on the connecting plate 140 , and the first supporting portion 141 extends to a side of the shielding plate 133 away from the air duct cavity and is connected to the shielding plate 133 .

[0071] Exemplarily, the first support portion 141 is provided at one end of the two connecting plates 140 away from the air duct outlet 120, and the shielding plate 133 extends to the side of the shielding plate 133 away from the air duct cavity. The first support portion 141 and the shielding plate 133 both have mounting holes, and the bolts pass through the mounting holes, so that the shielding plate 133 is connected to the connecting plate 140 through the first support portion 141, and is covered on the cleaning port 132. When the air duct needs to be cleaned, the shielding plate 133 is removed by removing the bolts for cleaning.

[0072] In some embodiments of the present application, the shielding plate 133 is connected to the two connecting plates 140 via butterfly screws 170 .

[0073] Exemplarily, the bolt used to connect the shielding plate 133 and the connecting plate 140 is a butterfly screw 170. The butterfly head design of the butterfly screw 170 allows workers to easily tighten or loosen it manually without using tools, which can be operated quickly and improves convenience.

[0074] The present application also provides an energy storage container 200 , which includes a plurality of battery clusters, an electrical room, a cooling unit, and an air duct, wherein the air duct is connected to an air outlet of the energy storage container 200 .

[0075] Exemplarily, the battery cluster generates heat when charging or discharging, and the cooling unit maintains the battery cluster operating within the optimal operating temperature range to effectively dissipate heat. The air outlet of the cooling unit discharges the hot air generated during the heat dissipation process. The cabinet door of the energy storage container 200 is provided with an air outlet corresponding to the air outlet of the cooling unit. The air outlet of the energy storage container 200 is connected to the air duct. The hot air flows from the air outlet of the energy storage container 200 into the air inlet 110 of the air duct, flows through the air duct cavity, and escapes from the air outlet 120 of the air duct to the upper end of the energy storage container 200.

[0076] The present application also provides an energy storage system, which includes a plurality of energy storage containers 200. The energy storage container 200 is provided with an air duct, and the hot air discharged from the air outlet of the energy storage container 200 is guided by the air duct to the upper end of the energy storage container 200 for dissipation.

[0077] In summary, the present application effectively optimizes the flow path of hot air by installing an air duct at the air outlet of the energy storage container 200. On the one hand, the air duct guides the hot air discharged from the air outlet of the energy storage container 200 directly to the air above the energy storage container 200, thereby preventing the hot air from flowing back to the air inlet of the energy storage container 200, eliminating the problem of hot air backflow, effectively solving the phenomenon of return air short circuit, ensuring the heat dissipation efficiency of the cooling unit, and greatly improving the stability of the operation of the energy storage system equipment; on the other hand, the energy storage container 200 includes an electrical room. After the hot air is directly guided to the air above the energy storage container 200, it is prevented from blowing to the electrical room, thereby reducing the risk of temperature increase of the electrical equipment due to heat accumulation, ensuring the normal operation of the electrical room, and extending its service life; further, after the hot air is directly guided to the air above the energy storage container 200, the hot air between the energy storage containers 200 can be effectively diffused, avoiding the problem of heat accumulation caused by the close arrangement of the energy storage containers 200, not only optimizing the airflow environment around the energy storage container 200, but also further reducing the risk of overheating and thermal runaway, improving the overall heat dissipation performance of the cooling unit, and improving the efficiency and safety of the entire energy storage system.
