Description

Technical Field

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

[0002] As the core component of energy storage cabinets, battery packs have high temperature requirements during use. Excessive temperature can cause irreversible damage to the battery cells, so temperature management of battery packs is particularly important.

[0003] In existing technologies, temperature management is mainly divided into two methods: air cooling and water cooling. Among them, air cooling equipment occupies a large space and the cost of air ducts is high. At the same time, air cooling requires a large heat dissipation gap between adjacent cells, resulting in low energy density of the battery pack.

[0004] Therefore, traditional energy storage cabinets mostly use water cooling for temperature management. Specifically, a water cooling system is integrated into the battery pack, and heat exchange pipes are used to cover the periphery of the battery pack. Cooling water supplied by the water cooling system circulates through the heat exchange pipes, thereby exchanging heat with the periphery of the battery pack and dissipating heat. However, if the water cooling system leaks, cooling water will seep into the battery pack, affecting the normal operation of the battery cells.

[0005] Therefore, the above problems urgently need to be solved. Utility Model Content

[0006] The purpose of this utility model is to provide an energy storage cabinet to solve the problem that if the water-cooling equipment leaks, the cooling water will seep into the battery pack, causing irreversible damage to the battery cells.

[0035] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0036] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0037] In this application, the term "and / or" describes a relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of only one centrifugal vortex magnetic pump, the simultaneous existence of one centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump, or the existence of only one centrifugal vortex magnetic pump. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0038] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0039] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0040] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0041] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0042] Please see Figures 1 to 4 This embodiment provides an energy storage cabinet, which includes a cabinet body 1, a partition 2, battery clusters 3, and a water-cooling device 4. The cabinet body 1 has at least one door 11 on its front. The partition 2 is disposed inside the cabinet body 1, dividing the interior of the cabinet body 1 into at least two receiving cavities. The battery clusters 3 include multiple battery packs 31, and each battery cluster 3 and the water-cooling device 4 is disposed in one receiving cavity. The water-cooling device 4 is connected to the cooling pipes of the multiple battery packs 31 via heat exchange pipes 5.

[0043] Generally, if the water-cooling device 4 leaks severely, it will cease to function properly and will issue an alarm to alert maintenance personnel for timely repairs. Therefore, placing the battery cluster 3 and the water-cooling device 4 in separate enclosures serves two purposes: firstly, it prevents the battery cluster 3 from being bumped during repairs of the water-cooling device 4; secondly, it isolates and temporarily stores leaked cooling water from the water-cooling device 4, facilitating timely cleanup by maintenance personnel.

[0044] However, even with a minor leak, the water-cooling device 4 can still operate normally, causing continuous leakage of cooling water during circulation, which usually goes unnoticed before routine maintenance. Therefore, preventative measures are needed for minor cooling water leaks. By placing the battery cluster 3 and the water-cooling device 4 in separate containment chambers, the leaked cooling water from the water-cooling device 4 will be temporarily stored within these chambers, effectively preventing continuous seepage of cooling water into the battery pack 31 and ensuring the normal operation of the battery cells.

[0045] Specifically, the heat exchange pipeline 5 includes an output pipe 51, an input pipe 52, multiple branch water supply pipes 53, and multiple branch return water pipes 54. The output pipe 51 is connected to the outlet of the water-cooling device 4. The input pipe 52 is connected to the inlet of the water-cooling device 4. The multiple branch water supply pipes 53 are connected to the cooling pipelines of multiple battery packs 31, and are all connected to the output pipe 51. The multiple branch return water pipes 54 are connected to the cooling pipelines of multiple battery packs 31, and are all connected to the input pipe 52. The output pipe 51, the multiple branch water supply pipes 53, the multiple branch return water pipes 54, and the input pipe 52 are connected to form a loop.

[0046] This configuration allows multiple battery packs 31 to form a parallel water-cooled structure, thereby increasing the flow rate and velocity of the cooling water, enhancing the efficiency of the water-cooling device 4, and ensuring better heat dissipation. Secondly, the parallel water-cooled structure ensures a relatively uniform cooling water flow to each battery pack 31, contributing to better heat dissipation and preventing any single battery pack 31 from experiencing poor heat dissipation due to insufficient cooling water.

[0047] To reduce the difficulty and cost of arranging the heat exchange pipes 5, the battery cluster 3 and the water cooling device 4 are respectively housed in two adjacent cavities. Furthermore, if the heat exchange pipes 5 are long, more condensate will form on their surface during use, and excessive condensate can seep into the battery pack 31, affecting the battery cells. Therefore, in this embodiment, placing the battery cluster 3 and the water cooling device 4 in two adjacent cavities effectively shortens the length of the heat exchange pipes 5, thereby reducing the amount of condensate forming on their surface during use, and consequently reducing the likelihood of condensate seeping into the battery pack 31 and affecting the battery cells.

[0048] It should be noted that the operating status of the water-cooling device 4 and the battery cluster 3 in existing energy storage cabinets is usually controlled by the control device 6. Therefore, in this embodiment, the energy storage cabinet also includes a control device 6, which is disposed in one of the receiving cavities and is communicatively connected to the water-cooling device 4 and the battery cluster 3. It should be noted that the working principle of the control device 6 is existing technology and will not be described in detail.

[0049] It should also be noted that existing energy storage cabinets require a transformer 7 to convert the output electrical signal of the battery cluster 3. However, existing transformers 7 are usually located outside the energy storage cabinet, which is an unreasonable arrangement and leads to the need for wiring and overhead wires during use. In this embodiment, the energy storage cabinet also includes a transformer 7, which is located inside one of the housing cavities. The transformer 7 is electrically connected to the battery cluster 3 to receive the DC signal output by the battery cluster 3 and convert the DC signal into an AC signal for output to an external load. This arrangement reduces the need for wiring and overhead wires during the use of the energy storage cabinet, making it easier to use.

[0050] To improve the convenience of monitoring the working status of various components inside the energy storage cabinet, multiple cabinet doors 11 are provided, with one door 11 corresponding to each of the two accommodating cavities that house the battery cluster 3 and the water-cooling equipment 4. This arrangement allows the corresponding cabinet door 11 to be opened when performing maintenance on a specific component inside the cabinet 1, thereby reducing the possibility of interfering with the normal operation of other components.

[0051] It is understandable that the water-cooled equipment 4 and the transformer 7 will generate a large amount of heat when they are working. Therefore, in order to avoid the water-cooled equipment 4 and the transformer 7 from overheating and affecting normal operation, in this embodiment, heat dissipation louvers 8 are provided on the cabinet doors 11 corresponding to the water-cooled equipment 4 and the transformer 7.

[0052] Furthermore, ventilation louvers 8 are provided on the back of the cabinet 1 at the positions corresponding to the water-cooling device 4 and the battery cluster 3. This arrangement can better dissipate heat from the water-cooling device 4 and also help improve the heat dissipation effect of the battery cluster 3.

[0053] During operation, multiple components within the energy storage cabinet 1 generate noise and vibration. If this noise and vibration are not controlled, it will have a significant negative impact on the production environment. Therefore, rock wool 9 is installed on the inner walls of multiple cavities. It is understandable that rock wool 9 effectively reduces noise and vibration. It is also understandable that the water-cooled equipment 4 requires good insulation to reduce energy loss; rock wool 9 also has excellent insulation properties, thus ensuring good cooling performance of the water-cooled equipment 4.

[0054] To improve the ease of handling the energy storage cabinet, multiple lifting rings 10 are distributed on the top of the cabinet 1. This arrangement allows cranes or overhead cranes to move the energy storage cabinet using the multiple lifting rings 10. In this embodiment, four lifting rings 10 are provided, with each ring 10 positioned at one of the four corners of the top of the cabinet 1.

[0055] 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 various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments 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.
