[0002] In energy storage systems, heat dissipation is crucial for the stable operation of battery packs. Currently, the main heat dissipation methods include air cooling, liquid cooling, and direct cooling, with air cooling being widely used due to its low cost and simple structure. However, the air duct design of air cooling suffers from air leakage, which reduces heat exchange efficiency. Traditionally, air leakage is addressed by adding sealing gaskets at the gaps, but the battery pack installation method requires pushing the battery pack into the mounting position from front to back via guide rails. During this sliding process, the sealing gaskets are prone to rolling over or shifting, affecting assembly and resulting in poor sealing performance. Utility Model Content

[0016] The technical solutions in this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0017] This application provides an energy storage cabinet and a battery pack. The energy storage cabinet is used to store and manage the battery pack, and it has functions such as heat dissipation and energy management. The battery pack is the energy storage unit in the energy storage cabinet, and it consists of, for example, battery cells, a casing, and a battery management system (BMS), used to store and release electrical energy. The energy storage cabinet and the battery pack work together to achieve energy storage and heat dissipation functions through the airflow design of the energy storage cabinet (e.g., the airflow between two adjacent battery packs), guide rail components, and the management system. In practical applications, such as data centers, photovoltaic power generation systems, and electric vehicle charging stations, the energy storage cabinet and the battery pack work together to ensure the storage and stable supply of electrical energy.

[0018] The following is combined Figures 1 to 4 The energy storage cabinet 100 of this application is described in detail. Figure 1 A schematic diagram of the internal structure of an energy storage cabinet 100 according to an embodiment of this application is shown. Figure 2 This illustration shows a partially enlarged view of the guide assembly and sealing assembly of an energy storage cabinet 100 according to an embodiment of this application. Figure 1 . Figure 3 This illustration shows a partially enlarged view of the guide assembly and sealing assembly of an energy storage cabinet 100 according to an embodiment of this application. Figure 2 . Figure 4 A schematic internal side view of an energy storage cabinet 100 according to an embodiment of this application is shown.

[0019] First refer to Figure 1 The energy storage cabinet 100 includes: a cabinet body 101, a support component 102, a guide component 103, a sealing component 104, and a battery pack 200. The support component 102 is disposed inside the cabinet body 101. The guide component 103 is fixedly connected to the support component 102 and is used to guide the battery pack 200 into the cabinet body 101. The guide component 103 is provided with a guide structure 103A. The sealing component 104 is disposed above and / or below the battery pack 200 along the height direction of the energy storage cabinet 100. The sealing component 104 matches the shape of the guide structure 103A.

[0020] For example, the cabinet 101 is the core component of the energy storage cabinet 100. The cabinet 101 provides physical housing space for internal components such as support components 102, guide components 103, sealing components 104 and battery pack 200, ensuring the installation and fixation of internal components.

[0021] The support assembly 102 is installed inside the cabinet 101 to provide stable support for the battery pack 200. The support assembly 102 can be composed of columns or frames, for example. The support assembly 102 can not only bear the weight of components such as the battery pack, but also distribute the weight to the bottom or side panels to avoid excessive local stress, and at the same time enhance the impact resistance of the energy storage cabinet 100.

[0022] Furthermore, the support component 102 may include multiple columns, and the guide component 103 is a guide rail mounted on the columns.

[0023] For example, the support component 102 can be composed of multiple columns, which can be arranged at equal intervals and fixedly connected between the bottom plate and the top plate of the cabinet 101 to form the frame of the energy storage cabinet. Each column can be provided with a row of holes to facilitate the installation of the guide component 103 (such as a guide rail). The guide component 103 can be composed of multiple guide rails, which can be connected to the columns by bolts or clips and can be adjusted along the height direction to adjust the layer spacing between two adjacent battery packs 200. At the same time, the cross section of the column and the cantilever section of the guide rail form a "T"-shaped load-bearing node, so that the weight of the battery pack 200 is distributed to the overall frame of the cabinet 101, thereby improving the stability and structural reliability of the energy storage cabinet 100.

[0024] The guide assembly 103 is fixedly connected to the support assembly 102 and is used to guide the battery pack 200 into the cabinet 101. A guide structure 103A (such as...) can be provided on the guide assembly 103. Figure 1 The guide structure 103A shown can be shaped to match other components (such as sealing assembly 104) to form a sealing interface.

[0025] The sealing assembly 104 is positioned above and / or below the battery pack 200 along the height direction of the energy storage cabinet 100. By matching with the guide structure 103A on the guide assembly 103, it achieves sealing while increasing the vertical clamping force on the battery pack 200, thus fixing the battery pack inside the energy storage cabinet 100 and providing support and fixation for the battery pack 200.

[0026] The sealing assembly 104 is shaped to match the guide structure 103A. Figure 2 This illustration shows a partially enlarged view of the guide assembly and sealing assembly of an energy storage cabinet according to an embodiment of this application. Figure 1 . Reference Figure 2The guide structure 103A can be a series of grooves and protrusions. The sealing assembly 104 is provided with grooves or protrusions corresponding to the guide structure 103A. The guide structure 103A and the sealing assembly 104 cooperate with each other to seal the air duct 105 between two adjacent battery packs 200. The shape matching of the guide structure 103A and the sealing assembly 104 will be described in detail below with specific examples.

[0027] Furthermore, the sealing assembly 104 may include a first seal 1041 and a second seal 1042, wherein the first seal 1041 and the second seal 1042 are respectively disposed at the top and bottom of the battery pack 200.

[0028] For example, continue to refer to Figure 1 The first seal 1041 and the second seal 1042 of the sealing assembly 104 are respectively disposed at the top and bottom of the battery pack 200. (Continue referring to...) Figure 1 The first sealing member 1041 can be disposed at the top of the battery pack 200, and the second sealing member 1042 can be disposed at the bottom of the battery pack 200. The first sealing member 1041 and the second sealing member 1042 not only provide stable support for the battery pack 200, but also, through the connection and cooperation between the first sealing member 1041 and the second sealing member 1042 and the guide assembly 103, can reduce the vibration and displacement of the battery pack 200 during operation. It is understood that the placement of the first sealing member 1041 and the second sealing member 1042 is merely exemplary. For example, the first sealing member 1041 can be disposed at the bottom of the battery pack 200, and the second sealing member 1042 can be disposed at the top of the battery pack 200. This application embodiment does not impose specific limitations, as long as the technical principles of this application can be achieved.

[0029] Furthermore, the first sealing member 1041 may be provided with a first structure 1041A, and the second sealing member 1042 may be provided with a second structure 1042A, wherein the first structure 1041A and the second structure 1042A are different.

[0030] For example, continue to refer to Figure 2 The first seal 1041 may be provided with a first structure 1041A (e.g., Figure 2 As shown in 1041A), the second sealing member 1042 may be provided with a second structure 1042A. The first structure 1041A and the second structure 1042A are respectively in close contact with the side of the guide structure 103A, thereby forming a sealing structure and preventing air leakage in the air duct 105.

[0031] Furthermore, the first structure 1041A and the second structure 1042A are respectively matched with the shape of the guide structure 103A.

[0032] For example, continue to refer to Figure 2 The guide structure 103A can be a concave-convex structure, and the first structure 1041A and the second structure 1042A can be structures corresponding to different sides of the concave-convex structure. For example, the guide structure 103A can be configured as a groove-boob spacing distribution, and the first structure 1041A and the second structure 1042A can be configured as a groove-boob spacing distribution corresponding to the guide structure 103A. That is, the grooves and bosses of the first structure 1041A and the second structure 1042A are positioned to correspond to the grooves or bosses on the contact surface of the guide structure 103A. After the two adjacent battery packs 200 are connected to the guide assembly 103 through the first seal 1041 and the second seal 1042, the first structure 1041A, the second structure 1042A and the guide structure 103A form a concave-convex sealing structure, so that the concave-convex structure on the bottom side of the upper battery pack (the second structure 1042A) and the concave-convex structure on the top side of the lower battery pack (the first structure 1041A) form a relatively sealed environment, thereby allowing the cold air to fully contact the surface of the battery pack 200 and preventing the cold air from leaking from the side.

[0033] For example, Figure 3 This illustration shows a partially enlarged view of the guide assembly and support assembly of an energy storage cabinet according to an embodiment of this application. Figure 2 .like Figure 3 As shown, one side of the guide structure 103A is flat, and the other side is concave-convex. In this case, the surface of the first sealing member 1041, which contacts the concave-convex side of the guide structure 103A, is a concave-convex structure corresponding to the concave-convex surface of the guide assembly 103. The surface of the second sealing member 1042, which contacts the guide assembly 103, is flat, thus fitting against the flat surface of the guide assembly 103 to form an end-face compression seal. It can be understood that the first structure on the first sealing member 1 is a concave-convex structure, and the second structure on the second sealing member is a flat structure. In this way, the first structure 1041A and the second structure 1042A respectively match the contact surface shape of the guide assembly 103, thereby forming a relatively sealed structure on the side of the air duct 105.

[0034] It is understood that the descriptions of guide structure 103A, first structure 1041A and second structure 1042A are merely exemplary. Those skilled in the art can select and configure guide structure 103A, first structure 1041A and second structure 1042A according to actual needs, as long as the technical principles of this application can be achieved.

[0035] Furthermore, the guide assembly 103, the sealing assembly 104, and the two adjacent battery packs 200 together form an air duct 105, wherein the guide assembly 103 and the sealing assembly 104 prevent air leakage from the air duct 105.

[0036] For example, continue to refer to Figure 1 The guide assembly 103, the sealing assembly 104, and the two adjacent battery packs 200 together form an air duct 105. Cool air passes through the air duct 105 and comes into contact with the surface of the battery packs 200, absorbing heat from the surface of the batteries 200. The sealing structure formed by the guide assembly 103 and the sealing assembly 104 ensures the airtightness of the air duct 105, preventing cool air from leaking from the side of the cabinet 101, thereby improving heat dissipation efficiency.

[0037] Furthermore, the first seal 1041 and the second seal 1042 extend along a first direction of the battery pack 200, and the extension dimension is equal to the length of the battery pack 200 in the first direction.

[0038] For example, the first seal 1041 and the second seal 1042 extend along the first direction (i.e., the length direction) of the battery pack 200, and the extension dimension of the first seal 1041 and the second seal 1042 is equal to the length of the battery pack 200. That is, the first seal 1041 and the second seal 1042 can cover the surface of the battery pack 200 along the entire length direction, so that the weight of the battery pack 200 can be transferred to the support assembly 102, thereby improving the structural strength of the energy storage cabinet 100.

[0039] It is understood that the above description of the cabinet 101, support component 102, guide component 103, sealing component 104, and battery pack 200 is merely exemplary. Those skilled in the art can select and configure the cabinet 101, support component 102, guide component 103, sealing component 104, and battery pack 200 according to actual needs, as long as the technical principles of this application can be achieved.

[0040] The energy storage cabinet 100 will be described in detail below in conjunction with specific application scenarios. Figure 4 A schematic internal side view of an energy storage cabinet according to an embodiment of this application is shown. (Refer to...) Figure 1 as well as Figure 4 The energy storage cabinet 100 includes an air-cooling component for supplying air into the cabinet 101. The air-cooling component can be located at the top of the energy storage cabinet 100 (e.g., the front of the top). The air-cooling component can consist, for example, of a centrifugal fan, a static pressure box, and a removable filter. When the fan is running, outside cold air passes through the filter for dust removal and enters the static pressure box, forming a uniform static pressure. Then, it enters the cabinet 101 through the air inlet and flows along the air duct (e.g., ...). Figure 4 (In the direction of the arrow) the air enters the air duct 105 between two adjacent battery packs 200. Under the sealed structure formed by the first structure 1041A and the second structure 1042A and the guide structure 103A respectively, the cold air can flow on the surface of the battery pack 200, thereby taking away the surface heat of the battery pack 200.

[0041] It should be noted that although the energy storage cabinet provided in this application has been described above in conjunction with the accompanying drawings, the scope of protection of this application is not limited to the description above. Figure 1 A vertically placed energy storage cabinet is shown, with guide assemblies 103 respectively disposed on the left and right sides of the energy storage cabinet 100. The energy storage cabinet 100 provided in this application can also be a horizontally placed energy storage cabinet (e.g., [the type of cabinet]). Figure 1 The energy storage cabinet shown is along Figure 1 (The plane shown is rotated 90 degrees clockwise). In this horizontally placed energy storage cabinet, guide components 103 are respectively arranged at the upper and lower parts of the energy storage cabinet 100. Correspondingly, the orientation of the battery pack 200 in the energy storage cabinet 100 is also equivalent to... Figure 1 The battery pack shown is rotated 90 degrees clockwise. Therefore, this type of horizontal energy storage cabinet can still install and support the battery pack 200 through the connection relationship between the guide assembly 103, the first structure 1041A, the second structure 1042A, and the guide structure 103A provided in this application, and can prevent air leakage between adjacent battery packs 200.

The guide assembly 103 may be provided with a guide structure 103A, which can be matched in shape with other components (such as the sealing assembly 104) to form a sealing interface.

[0045] The sealing assembly 104 is positioned above and / or below the battery pack 200 along the height direction of the energy storage cabinet 100. By matching with the guide structure 103A on the guide assembly 103, it achieves sealing while increasing the vertical clamping force on the battery pack 200, thus fixing the battery pack 200 inside the energy storage cabinet 100.

[0046] In this embodiment, the arrangement, connection relationship and function of the guide component 103, sealing component 104 and guide structure 103A are the same as or similar to the description of the embodiment described above, and will not be repeated here.

[0047] Furthermore, the sealing assembly 104 may include a first seal 1041 and a second seal 1042, the first seal 1041 and the second seal 1042 being located at the top and bottom of the battery pack 200, respectively.

[0048] For example, continue to refer to Figure 5 The first sealing member 1041 is disposed on the top of the battery pack 200, and the second sealing member 1042 is symmetrically disposed on the bottom of the battery pack 200, forming a symmetrical arrangement in the height direction. The first sealing member 1041 and the second sealing member 1042 can extend along the length direction of the battery pack body, thereby fixing the entire battery pack body.

[0049] Furthermore, the first sealing member 1041 may be provided with a first structure 1041A, and the second sealing fixing member 1042 may be provided with a second structure 1042A, wherein the first structure 1041A and the second structure 1042A are different.

[0050] For example, refer to Figure 2 and Figure 5 The first seal 1041 may be provided with a first structure 1041A (e.g., Figure 2 As shown in 1041A), the second seal 1042 may be provided with a second structure 1042A (such as...). Figure 2 As shown in 1042A), the first structure 1041A and the second structure 1042A are tightly fitted to the side of the guide structure 103A, thereby forming a sealing structure.

[0051] In this embodiment, the arrangement, connection relationship and function of the components such as the first seal 1041, the first structure 1041A, the second seal 1042, the second structure 1042A and the guide structure 103A are the same as or similar to the description in the above embodiment, and will not be repeated here.
