Description

Technical Field

[0001] This utility model belongs to the field of energy storage cabinet technology, and in particular relates to an air-cooled energy storage cabinet. Background Technology

[0002] Most energy storage cabinets on the market are equipped with a heat dissipation system, with liquid cooling or air cooling being the most common methods. When air cooling is used, heat dissipation ducts are typically installed between the battery packs. External airflow enters the heat dissipation ducts from the top, exchanges heat with the battery pack casing, and then exits from the bottom, thus achieving heat dissipation for the battery packs.

[0003] For large energy storage cabinets, which typically house numerous battery packs, cooling air conditioners are often installed on opposite sides of the cabinet to provide cooling airflow to the battery packs. However, in actual use, the cooling airflow from these two air conditioners can clash, causing a large amount of cooling air to accumulate at the top of the cabinet. This results in insufficient cooling airflow to the battery packs located at the bottom of the cooling duct, leading to increased temperature differences within the battery packs. This negatively impacts the performance and lifespan of the battery packs, and ultimately reduces the safety and performance of the entire energy storage cabinet.

[0004] Based on the above, there is an urgent need for an air-cooled energy storage cabinet to solve the technical problems existing in the current technology. Utility Model Content

[0005] The purpose of this utility model is to provide an air-cooled energy storage cabinet, which aims to reduce the temperature difference of the battery packs inside the cabinet, ensure that all battery packs can receive sufficient cooling airflow, thereby guaranteeing the performance and service life of the battery packs, and thus improving the safety and performance of the energy storage cabinet.

[0012] Optionally, a second baffle is also included, which is fixed above the top battery pack and located between the refrigeration air conditioners spaced apart along the second horizontal direction, and the main surface of the second baffle extends along the first horizontal direction.

[0013] Optionally, it also includes a partition column, which extends vertically within the heat dissipation duct to divide the heat dissipation duct vertically.

The high-voltage box includes two positive terminal connection components, each of which is connected to one of the battery clusters. The negative terminal connection component of the high-voltage box is located inside the cabinet.

[0017] The beneficial effects of the air-cooled energy storage cabinet provided by this utility model are as follows: by setting the guide plate on the flow path of the cooling airflow and tilting the guide plate relative to the first horizontal direction, the guide plate can guide the cooling airflow output from the air conditioner to change the flow direction and make it all flow into the heat dissipation duct, thereby avoiding the collision of the relatively flowing cooling airflows, ensuring that the battery pack located at the bottom of the heat dissipation duct can receive sufficient cooling airflow, thereby ensuring the normal charging and discharging performance of the battery pack, improving the service life of the battery pack, and thus improving the safety and performance of the air-cooled energy storage cabinet.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] The following is combined Figures 1 to 10 The present invention will be described in conjunction with specific embodiments of the air-cooled energy storage cabinet provided. Figure 1 , Figure 2 and Figure 7 As shown, the air-cooled energy storage cabinet includes a cabinet body 1, a battery rack 2, and a heat dissipation assembly 3. The battery rack 2 is located inside the cabinet body 1 and is used to fix and install the battery clusters. The heat dissipation assembly 3 includes a cooling air conditioner 31 fixedly installed outside the cabinet body 1. During the charging and discharging process of the battery clusters, the cooling air conditioner 31 can cool and dissipate heat from the battery clusters to ensure the safety of the air-cooled energy storage cabinet.

[0042] Specifically, such as Figure 1 As shown, the cabinet 1 is equipped with a double-opening cabinet door 11 and a single-opening cabinet door 12, which can be rotated to open or close the cabinet 1 and improve the practicality of the air-cooled energy storage cabinet.

[0043] Specifically, in this embodiment, nine battery clusters are installed on the battery rack 2, each battery cluster comprising 19 battery packs 100 connected in series. A high-voltage box 200 for connecting to the battery clusters is installed on the battery rack 2. The battery packs 100 and the high-voltage box 200 are fixed in place by battery compartments and high-voltage box compartments within the battery rack 2 to prevent them from shaking or bumping. In this embodiment, two positive terminal connection components are provided inside the high-voltage box 200, and the negative terminal connection component inside the high-voltage box 200 is removed and placed on one side of the battery rack 2. Thus, in this embodiment, one high-voltage box 200 can be connected to the positive terminals of two battery clusters, eliminating the need for nine high-voltage boxes 200 to connect to nine battery clusters. Therefore, only five high-voltage box compartments need to be reserved in the battery rack 2 for installing the high-voltage boxes 200, and the remaining four high-voltage box compartments can all be used as battery compartments, allowing the battery rack 2 to accommodate four additional battery packs 100, thereby effectively improving the energy density of the air-cooled energy storage cabinet.

[0044] Combination Figures 3 to 5 As shown, the battery rack 2 is divided into two parts. Each part of the battery rack 2 includes steel frames 21 spaced apart along a first horizontal and vertical direction, and supporting columns 22 fixedly connected to the steel frames 21, so that multiple compartments can be formed in the first horizontal and vertical directions. One part of the compartments is used as a high-voltage box compartment, and the other part is used as a battery compartment. The two parts of the battery rack 2 are arranged one after the other along a second horizontal direction. It should be noted that in this embodiment, the length direction of the battery rack 2 is defined as the first horizontal direction. Figure 2 As shown on the X-axis; the width direction of battery holder 2 is the second horizontal direction, as shown... Figure 2As shown on the Y-axis. The front battery rack 2 is used to install 19 battery packs 100 in the first four battery clusters, the first 10 battery packs 100 in the fifth battery cluster, and the first two high-voltage boxes 200. The rear battery rack 2 is used to install the last nine battery packs 100 in the fifth battery cluster, the 19 battery packs 100 in the last four battery clusters, and the last three high-voltage boxes 200. By continuously combining and arranging them, the compartments formed within the battery rack 2 can all be occupied by either battery packs 100 or high-voltage boxes 200. Through the above arrangement, the air-cooled energy storage cabinet provided in this embodiment can be increased from 2MWH to 3MWH, thereby significantly improving the space utilization and energy density of the air-cooled energy storage cabinet.

[0045] Furthermore, such as Figure 5 As shown, steel frames 21 are fixedly connected to opposite sides of the supporting column 22 along the first horizontal direction to form multiple heat dissipation ducts 23 within the battery rack 2 along the first horizontal direction. The heat dissipation component 3 can provide cooling airflow to the heat dissipation ducts 23, thereby dissipating and cooling the battery pack 100 on opposite sides. Preferably, in this embodiment, the length of the heat dissipation duct 23 along the first horizontal direction is 50-60mm. For example, the length of the heat dissipation duct 23 can be 50mm, 55mm, or 60mm to prevent the length of the heat dissipation duct 23 from being too long, which would slow down the rate at which the cooling airflow enters the heat dissipation duct 23, resulting in insufficient cooling airflow to diffuse to the bottom of the heat dissipation duct 23; or to avoid the length of the heat dissipation duct 23 from being too short, resulting in less cooling airflow entering the heat dissipation duct 23, thus leading to wasted cooling airflow and poor cooling effect.

[0046] Furthermore, refer to Figure 5 , Figure 6 As shown, the air-cooled energy storage cabinet also includes a partition column 4, which extends vertically and is installed in the heat dissipation duct 23 so that the partition column 4 can divide the heat dissipation duct 23 into multiple ducts with smaller inlet cross-sectional areas in the vertical direction. This can accelerate the rate at which the cooling airflow enters the heat dissipation duct 23, thereby further ensuring that there is sufficient cooling airflow to diffuse to the battery pack 100 located at the bottom of the battery rack 2.

[0047] refer to Figure 7 As shown, in this embodiment, the length of the battery rack 2 along the second horizontal direction reaches 1937mm, resulting in a relatively long heat dissipation duct 23. Therefore, in this embodiment, a cooling air conditioner 31 is fixedly installed on the top of both opposite sides of the cabinet 1 so that both opposite sides of the heat dissipation duct 23 have a cooling airflow flowing from the edge to the center, ensuring that all battery packs 100 on the battery rack 2 can receive the cooling airflow.

[0048] However, in actual use, the cooling airflow provided by the air conditioning units 31 on both sides of the cabinet 1 will cause the cooling airflow to collide, resulting in a large amount of cooling airflow accumulating at the top of the cabinet 1. This causes the battery pack 100 located at the bottom of the heat dissipation duct 23 to not receive enough cooling airflow, thereby increasing the temperature difference of the battery pack 100 inside the energy storage cabinet, affecting the performance and lifespan of the battery pack 100, and reducing the safety and performance of the energy storage cabinet.

[0049] To address the aforementioned issues, the heat dissipation assembly 3 provided in this embodiment further includes a guide plate 32. The guide plate 32 is located on the flow path of the cooling airflow and is inclined relative to the first horizontal direction to guide the cooling airflow output from the air conditioning unit 31 to change its flow direction and direct all of it into the heat dissipation duct 23 (see reference). Figure 7 (as indicated by the solid arrow in the middle), thereby avoiding the collision of cooling airflows flowing in opposite directions along the second horizontal direction, ensuring that the battery pack 100 located at the bottom of the heat dissipation duct 23 can receive sufficient cooling airflow, thus ensuring the normal charging and discharging performance of the battery pack 100, improving the service life of the battery pack 100, and further improving the safety and performance of the air-cooled energy storage cabinet.

[0050] When installing the air deflector 32, attention must be paid to the ease and accuracy of installation to ensure installation efficiency. To achieve the above objectives, in this embodiment, reference is made to... Figure 8 As shown, the guide plate 32 includes a first plate 321 and a second plate 322. The first plate 321 and the second plate 322 are L-shaped plates to enhance the structural strength of the guide plate 32. The first plate 321 has a first mounting through hole 3211 on its horizontal portion and a first mounting threaded hole on the inner side wall of the cabinet 1. The first mounting threaded hole and the first mounting through hole 3211 are fixedly connected by threaded connectors (e.g., bolts, screws). The second plate 322 has a second mounting through hole 3221 on its horizontal portion and a second mounting threaded hole on the top of the battery rack 2. The second mounting through hole 3221 and the second mounting threaded hole are also fixedly connected by threaded connectors, thereby facilitating the assembly and disassembly of the guide plate 32 and ensuring installation efficiency. Furthermore, a third mounting through hole 3212 is provided on the vertical part of the first plate 321, and a fourth mounting through hole 3222 is provided on the vertical part of the second plate 322. The fourth mounting through hole 3222 is an oblong hole. The third mounting through hole 3212 and the fourth mounting through hole 3222 are also fixedly connected by threaded connectors. Moreover, the second plate 322 and the first plate 321 can slide relative to each other in the vertical direction. In this way, the guide plate 32 can be reasonably adjusted according to the actual distance between the inner top wall of the cabinet 1 and the top of the battery rack 2 during specific installation, making up for installation tolerances and thus improving installation accuracy.

[0051] Preferably, combined with Figure 8 , Figure 9 As shown, in this embodiment, the length range L of the first plate 321 and the second plate 322 along the flow path of the cooling airflow is 140-150mm, and the angle range α of the inclination relative to the first horizontal direction is 45°-50°, so as to ensure that the cooling airflow can be evenly distributed in the heat dissipation duct 23 within the length and inclination angle range of the guide plate 32, and the battery pack 100 located at the bottom of the heat dissipation duct 23 can be cooled to a suitable temperature range.

[0052] Furthermore, to further reduce the risk of airflow collision, multiple guide vanes 32 are spaced apart along the flow path of the cooling airflow in the second horizontal direction. Cooling airflow escaping from the edge of the preceding guide vane 32 can be blocked by the following guide vane 32 and then guided into the heat dissipation duct 23, thereby further reducing the phenomenon of airflow collision and improving the utilization rate of the cooling airflow. Those skilled in the art can select the number of guide vanes 32 according to actual needs; this invention is not limited in this respect.

[0053] refer to Figure 7 As shown, in this embodiment, the length of the battery rack 2 along the first horizontal direction reaches 6558mm. Therefore, along the first horizontal direction, multiple cooling air conditioners 31 and deflectors 32 are spaced apart on the cabinet 1 to ensure that the battery packs 100 arranged along the first horizontal direction can receive sufficient cooling airflow. In addition, the air-cooled energy storage cabinet also includes a first baffle 5, which is fixedly installed on the top of the battery rack 2 and located at the intersection of the cooling airflows flowing relatively along the first horizontal direction (see reference). Figure 7 As shown by the dashed arrow i and the solid arrow ii), the main surface of the first baffle 5 extends along the second horizontal direction. By setting the first baffle 5, the cooling airflow flowing in opposite directions along the first horizontal direction can be prevented from colliding and generating eddies at the intersection, and can be rebounded by the first baffle 5 back into the heat dissipation duct 23, thereby improving the cooling efficiency of the air-cooled energy storage cabinet.

[0054] Further reference Figure 7As shown, the air-cooled energy storage cabinet provided in this embodiment also includes a second baffle 6. The second baffle 6 is fixedly installed on the top of the battery rack 2 and located between the cooling air conditioners 31 that are spaced apart along the second horizontal direction, and the main surface of the second baffle 6 extends along the first horizontal direction. Since the number of guide plates 32 arranged along the second horizontal direction is limited, and the pressure and flow rate of the cooling air provided by the cooling air conditioners 31 are usually large, it is inevitable that a small amount of cooling air will still leak from the edge of the guide plate 32 located at the rear. The setting of the second baffle 6 can fundamentally prevent the cooling airflow flowing in opposite directions along the second horizontal direction from colliding, and under the action of the second baffle 6, the residual cooling airflow can be guided into the heat dissipation duct 23, making the cooling airflow entering the heat dissipation duct 23 more uniform and sufficient.

[0055] To facilitate the installation and fixing of the first baffle 5 and the second baffle 6, in this embodiment, the specific structural types of the first baffle 5 and the second baffle 6 are similar to those of the guide plate 32, ensuring that the first baffle 5 and the second baffle 6 also have the advantages of easy installation and high precision. The only difference is that the specific shape and size of the first baffle 5 and the second baffle 6 differ from those of the guide plate 32, in order to satisfy the function of the first baffle 5 and the second baffle 6 in blocking the counterflow of cooling airflow. Therefore, the specific structure of the first baffle 5 and the second baffle 6 will not be described in detail in this utility model.

[0056] Optionally, refer to Figure 10 As shown, the air-cooled energy storage cabinet provided in this embodiment also includes a gas fire suppression system 7. The gas fire suppression system 7 is installed inside the cabinet 1 and is located on top of the battery rack 2. Referring to the prior art, the gas fire suppression system 7 includes conventionally arranged components such as gas cylinders, gas fire suppression pipes, and release nozzles. Those skilled in the art can ensure that the gas fire suppression system 7 can completely cover the battery pack 100 on the battery rack 2 by reasonably arranging the layout and setting the number of gas fire suppression systems 7, thereby improving the timeliness and effectiveness of the gas fire suppression system 7 in extinguishing fires.

[0057] Furthermore, in this embodiment, the air-cooled energy storage cabinet also includes a water-based fire suppression system 8, which is installed inside the cabinet 1 and also positioned on top of the battery rack 2. Referring to existing technology, the water-based fire suppression system 8 includes conventionally installed components such as a water tank, water-based fire suppression pipes, and sprinklers. The arrangement of the water-based fire suppression system 8 is similar to that of the air-based fire suppression system 7, ensuring that the water-based fire suppression system 8 can also fully cover the battery packs 100 on the battery rack 2. Through the dual protection of the water-based fire suppression system 8 and the air-based fire suppression system 7, the safety of the air-cooled energy storage cabinet is greatly improved. Of course, those skilled in the art can also choose to install only the air-based fire suppression system 7 or the water-based fire suppression system 8 inside the cabinet 1, depending on factors such as cost, space, and the number of battery packs 100, to meet the user's basic needs.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
