To maintain the temperature of the battery cell packs within a suitable range, temperature control equipment (such as an air conditioner) can be installed inside the cabinet to regulate their temperature.

[0051] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0052] In the description of this disclosure, it should be understood that the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the accompanying drawings (such as...). Figure 3 The orientation of the drawing is defined only for the convenience of describing this disclosure and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation construction and operation, and therefore should not be construed as a limitation of this disclosure. In addition, the terms "inner" and "outer" refer to the inner and outer contours of the corresponding structures. Furthermore, the terms "first," "second," etc., are only used to distinguish one element from another and do not have any order or importance.

[0053] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0054] In related technologies, the energy storage cabinet contains battery cells for energy storage and temperature control equipment for temperature control. After openings are made on the cabinet door for heat exchange between the temperature control equipment and the outside environment, a gap exists between the cabinet door and the temperature control equipment, resulting in weak dustproof and waterproof performance of the energy storage cabinet.

[0055] In view of this, such as Figures 1 to 8 As shown, this disclosure provides a sealing structure 30 for an energy storage cabinet 10 in a first aspect, applied to the energy storage cabinet 10. The cabinet door of the energy storage cabinet 10 is provided with an opening 110, the position of which is adapted to be opposite to the heat exchange section 300 of the temperature control device 20. The sealing structure 30 includes a magnetically attracted sealing member 500 configured as an annular shape, the magnetically attracted sealing member 500 being adapted to be arranged around the opening 110 and adapted to seal the gap between the cabinet door 100 and the temperature control device 20 (such as the heat exchange section 300).

[0056] Through the above technical solution, when the cabinet door 100 is closed, the magnetic attraction property of the magnetic sealing component 500 is used to attract the cabinet door 100 and the temperature control device 20, thereby achieving the connection between the cabinet door 100 and the temperature control device 20 and sealing the gap between the cabinet door 100 and the temperature control device 20 (such as the heat exchange section 300). This achieves rapid sealing of the gap between the cabinet door and the temperature control device 20 (such as the heat exchange section 300), which is convenient to operate and simplifies the structure of the entire sealing structure 30. The magnetic sealing component 500 also helps to ensure the dustproof performance inside the energy storage cabinet 10, and at the same time, it can also ensure the waterproof performance of the energy storage cabinet 10 to a certain extent.

[0057] It should be noted that in the above solution, the opening 110 on the cabinet door 100 connects the inner and outer sides of the cabinet door 100. The opening 110 can be formed by a single hole structure on the cabinet door 100, or by a combination of multiple hole structures on the cabinet door 100. This embodiment does not impose specific limitations on this. Furthermore, in some optional embodiments, a grille, mesh panel, or other structure can be provided at the end of the opening 110 near the outer side of the cabinet door 100.

[0058] Furthermore, it can be understood that the position of the opening 110 is suitable for being positioned relative to the heat exchange section 300 of the temperature control device 20, including both a position where the opening 110 is directly opposite the heat exchange section 300 of the temperature control device 20 and a position where the opening 110 is offset from the heat exchange section 300 of the temperature control device 20. A direct alignment means that when the cabinet door 100 is closed, the projection of the entire heat exchange section 300 onto the cabinet door 100 is entirely within the opening 110, allowing the entire heat exchange section 300 to communicate with the outside of the energy storage cabinet for overall heat exchange. An offset configuration means that when the cabinet door 100 is closed, a portion of the projection of the heat exchange section 300 onto the cabinet door 100 is within the opening 110, allowing a portion of the heat exchange section 300 to communicate with the outside of the energy storage cabinet for partial heat exchange. When the cabinet door 100 is closed and the projection of the entire heat exchange section 300 on the cabinet door 100 is located within the opening 110, the end of the heat exchange section 300 of the temperature control device 20 can be inserted into the opening 110, extended out of the opening 110, or not inserted into the opening 110. This disclosure does not impose any specific restrictions on this.

[0059] In some alternative embodiments, the sealing structure 30 further includes: a first annular frame 400 adapted to be disposed on the cabinet door 100, the first annular frame 400 forming an insertion port 401 for the temperature control device 20 (such as the heat exchange section 300) to be inserted, the insertion port 401 being positioned opposite to the opening 110; and a magnetic sealing member 500 adapted to be arranged around the insertion port 401 and adapted to seal the gap between the first annular frame 400 and the temperature control device 20.

[0060] Since the insertion port 401 constructed by the first annular frame 400 is opposite to the opening 110, the temperature control device 20 can be inserted into the insertion port 401 after the cabinet door 100 of the energy storage cabinet 10 is closed. Since the magnetic sealing member 500 is arranged around the insertion port 401, after the temperature control device 20 (such as the heat exchange part 300) is inserted into the insertion port 401, the magnetic sealing member 500 can simultaneously connect the first annular frame 400 and the circumferential wall of the temperature control device 20, so that the magnetic sealing member 500 can seal the gap between the first annular frame 400 and the temperature control device 20, so that the gap between the first annular frame 400 and the temperature control device 20 cannot communicate with the opening 110, thereby achieving a sealed connection between the cabinet door 100 and the temperature control device 20.

[0061] It is understood that in some alternative implementations, such as Figure 1As shown, after the temperature control device 20 is inserted into the insertion port 401, the entire heat exchange section 300 on the temperature control device 20 is also inserted into the insertion port 401, so that the heat exchange section 300 can communicate with the outside of the energy storage cabinet for heat exchange through the insertion port 401. Of course, in some other optional embodiments, after the temperature control device 20 is inserted into the insertion port 401, only a portion of the heat exchange section 300 on the temperature control device 20 may be inserted into the insertion port 401.

[0062] The temperature control device 20 mentioned above may include, but is not limited to, air conditioners, fans, etc. When the temperature control device 20 is an air conditioner, the heat exchange section 300 may be a heat exchanger.

[0063] Furthermore, it should be noted that in the above solution, when a magnetic sealing element 500 is used for sealing, the component magnetically attracted by the magnetic sealing element 500 has a metallic material capable of magnetic attraction with the magnetic sealing element 500. This metallic material includes, but is not limited to, stainless steel, iron, and permanent magnets. The magnetic sealing element 500 can be fixed to the first annular frame 400 and magnetically fixed to the heat exchange part 300; it can also be fixed to the heat exchange part 300 and magnetically fixed to the first annular frame 400; or it can be magnetically fixed to both the heat exchange part 300 and the first annular frame 400. This disclosure does not impose specific limitations on these aspects.

[0064] In one embodiment provided in this disclosure, the magnetic seal 500 is fixed to the first annular frame 400.

[0065] To further improve the dustproof and waterproof performance of the energy storage cabinet 10, in some optional embodiments, the first annular frame 400 has a first annular surface 411 and a second annular surface 421 suitable for cooperating with the heat exchange section 300; the first annular surface 411 and the second annular surface 421 are arranged at an angle, and the second annular surface 421 is closer to the insertion port 401 than the first annular surface 411; the first annular surface 411 is sealed to the heat exchange section 300 by a magnetic sealing member 500.

[0066] After the heat exchange section 300 of the temperature control device 20 is inserted into the insertion port 401, a first gap is formed between the first annular surface 411 and the heat exchange section 300, and a second gap is formed between the second annular surface 421 and the heat exchange section 300. The second annular surface 421 is positioned closer to the insertion port 401 than the first annular surface 411, so that external dust, liquids, and other substances will pass through the first gap before reaching the second gap. The magnetic seal 500 is sealed to both the first annular surface 411 and the heat exchange section 300; therefore, external dust, liquids, and other substances will pass through the first gap before reaching the magnetic seal 500. By arranging the first annular surface 411 and the second annular surface 421 at an angle, the first gap and the second gap formed are also arranged at an angle. This causes dust, liquid and other substances entering the first gap to have to turn before reaching the magnetic seal 500, thereby preventing liquid from directly washing over the magnetic seal 500. This further improves the waterproof performance of the sealing structure 30 and enhances the waterproof rating of the energy storage cabinet 10.

[0067] It should be noted that the first annular surface 411 and the second annular surface 421 are set at an angle, meaning that the first annular surface 411 and the second annular surface 421 are not on the same plane. The first annular surface 411 and the second annular surface 421 can be connected, that is, one end of the first annular surface 411 and the second annular surface 421 are connected, or the second annular surface 421 can be spaced apart, that is, an intermediate surface is provided between the first annular surface 411 and the second annular surface 421, and both the first annular surface 411 and the second annular surface 421 are connected to this intermediate surface.

[0068] Regarding the specific angles of the first annular surface 411 and the second annular surface 421, in some optional embodiments, the first annular surface 411 and the second annular surface 421 are arranged at an angle of 64°-116°. Within this angle range, better waterproof performance can be achieved between the cabinet door 100 and the heat exchange section 300 of the temperature control device 20.

[0069] It should be noted that the angle between the first annular surface 411 and the second annular surface 421 is Figure 5 The angle α shown. A more specific selection of the angle between the first annular surface 411 and the second annular surface 421 can be made according to the shape of the heat exchange section 300 of the air conditioner. In some alternative embodiments, the first annular surface 411 and the second annular surface 421 may specifically be perpendicular to each other.

[0070] For the specific structure of the first annular frame 400 forming the first annular surface 411 and the second annular surface 421, in some optional embodiments, the first annular frame 400 may include a first frame body 410 and a second frame body 420 connected to each other, the first frame body 410 having the first annular surface 411 as described above, and the second frame body 420 having the second annular surface 421 as described above.

[0071] To further improve the waterproof performance between the cabinet door 100 and the heat exchange section 300 of the temperature control device 20, in some optional embodiments, the first annular frame 400 also has a third annular surface 431 suitable for cooperating with the heat exchange section 300. The first annular surface 411 is connected to one end of the second annular surface 421, and the third annular surface 431 is connected to the end of the second annular surface 421 away from the first annular surface 411. The third annular surface 431 is arranged at an angle to the second annular surface 421, and the third annular surface 431 is closer to the insertion port 401 than the second annular surface 421.

[0072] The third annular surface 431 is provided, forming a third gap between the third annular surface 431 and the heat exchange part 300. The third annular surface 431 is closer to the insertion port 401 than the second annular surface 421, ensuring that external dust, liquids, and other substances must pass through the third gap, the second gap, and the first gap sequentially before reaching the magnetic seal 500. Arranging the third and second gaps at an angle further prevents liquid from directly impacting the magnetic seal 500, thus improving the waterproof performance between the cabinet door 100 and the heat exchange part 300 of the temperature control device 20.

[0073] Regarding the specific angle between the third annular surface 431 and the second annular surface 421, in some optional embodiments, the third annular surface 431 and the second annular surface 421 are arranged at an angle of 89°-91°. Within this angle range, better waterproof performance can be achieved between the cabinet door 100 and the heat exchange section 300 of the temperature control device 20.

[0074] It should be noted that the angle between the third annular surface 431 and the second annular surface 421 is Figure 5 The β angle is shown. A more specific selection of the angles for the first annular surface 411 and the second annular surface 421 can be made according to the shape of the heat exchange section 300 of the air conditioner. In some alternative embodiments, the third annular surface 431 and the second annular surface 421 may specifically be perpendicular to each other.

[0075] In some alternative embodiments, the first annular surface 411 may be parallel to the third annular surface 431. This arrangement facilitates the machining of the first annular frame 400 and also allows it to cooperate with the heat exchange section 300. For example, in the following embodiment, after the cabinet door 100 is closed, the first annular surface 411 may face and cooperate with the axial end face of the heat exchange section 300, the second annular surface 421 may face and cooperate with the circumferential side surface of the heat exchange section 300, and the first annular surface 411 may cooperate with other components fixed to the circumferential side surface of the heat exchange section 300.

[0076] To further improve waterproof performance, in some optional embodiments, the sealing structure 30 further includes a first sealing element 600, which is an annular element adapted to be arranged around the insertion port 401; wherein, the first sealing element 600 is adapted to seal the gap between the third annular surface 431 and the heat exchange part 300, and / or, the first sealing element 600 is adapted to seal the gap between the second annular surface 421 and the heat exchange part 300.

[0077] Since external substances need to pass through the third gap formed between the third annular surface 431 and the heat exchange part 300 and the second gap formed between the second annular surface 421 and the heat exchange part 300 in order to reach the location of the magnetic seal 500, the first seal 600 can seal the first gap and / or the second gap, further improving the sealing performance between the door frame and the heat exchange part 300 of the temperature control device 20 and improving the waterproof and dustproof rating of the energy storage cabinet 10.

[0078] It should be noted that in the above scheme, the first sealing element 600 can be fixed to the first annular frame 400 and pressed against the heat exchange part 300 to achieve a seal; the magnetic sealing element 500 can also be fixed to the heat exchange part 300 and pressed against the first annular frame 400 to achieve a seal. This disclosure does not impose specific limitations in this regard.

[0079] In one embodiment provided in this disclosure, the first seal 600 is fixed to the heat exchange section 300.

[0080] To ensure that both the magnetic seal 500 and the first seal 600 can be compressed and sealed when the cabinet door 100 is closed, in one optional embodiment of this disclosure, both the magnetic seal 500 and the first seal 600 are configured to be compressible, with the compression stroke of the magnetic seal 500 being greater than that of the first seal 600. Thus, during the closing of the cabinet door 100, the magnetic seal 500 can be configured to seal the gap between the first annular frame 400 and the temperature control device 20 before the first seal 600, thereby prioritizing the seal between the magnetic seal 500 and the temperature control device 20. Furthermore, since both the magnetic seal 500 and the first seal 600 are compressible, during the compression deformation of the magnetic seal 500, both can achieve better contact and sealing with the first annular frame 400 and the temperature control device 20.

[0081] The material of the first sealing element 600 can be a foamed sealant, a vulcanized sealant, or other types of sealant; this disclosure does not impose specific limitations on this. In some optional embodiments provided in this disclosure, the first sealing element 600 can be a foamed sealant. Foamed sealants have characteristics such as low water absorption and excellent aging resistance, and can withstand the direct impact of water flow.

[0082] Regarding the specific shape of the first annular frame 400, in one optional embodiment provided in this disclosure, the first annular frame 400 includes a first frame body 410, a second frame body 420, and a third frame body 430 connected in sequence. The first frame body 410 has a first annular surface 411, the second frame body 420 has a second annular surface 421, and the third frame body 430 has a third annular surface 431. The first annular frame 400, composed of the first frame body 410, the second frame body 420, and the third frame body 430, can reduce the material used in the first annular frame 400 while achieving the sealing structure 30 and the sealing effect.

[0083] It should be noted that the first frame 410, the second frame 420 and the third frame 430 can be integrally formed, or they can be fixed together by welding, snap-fit ​​or other connection methods. This disclosure does not impose any specific restrictions on this.

[0084] This disclosure does not limit the specific structure of the magnetic seal; the following will combine [the description of the magnetic seal]. Figure 7 A detailed explanation will be provided.

[0085] like Figure 7As shown, the magnetic sealing member 500 includes an outer sleeve 510 and a magnetic member 520; the outer sleeve 510 has a cavity 501 inside, and the magnetic member 520 is disposed in the cavity 501; the outer sleeve 510 has a first connecting surface and a second connecting surface opposite each other, the first connecting surface is adapted to be connected to the first annular frame 400, and the magnetic member 520 is located on the side of the cavity 501 near the second connecting surface, so that the second connecting surface is adapted to be magnetically connected to the heat exchange part 300.

[0086] The outer sleeve 510 provides a mounting base for the magnetic component 520 on the one hand, and on the other hand, when the outer sleeve 510 is elastic, it can provide the required compression stroke for the magnetic seal. When the magnetic seal 500 is compressed, the outer sleeve 510 can undergo elastic deformation.

[0087] Regarding the cross-sectional shape of the magnetic sealing element 500, in some optional embodiments, the outer sleeve 510 includes a first connecting wall 511, a first side wall 512, a second connecting wall 513, and a second side wall 514 connected in sequence; the first connecting wall 511, the first side wall 512, the second connecting wall 513, and the second side wall 514 enclose and define a cavity 501; the first connecting wall 511 is opposite to the second connecting wall 513, the first connecting wall 511 has the aforementioned first connecting surface on the side away from the second connecting wall 513, and the second connecting wall 513 has the aforementioned second connecting surface on the side away from the first connecting wall 511; at least a portion of the first side wall 512 is constructed with a serrated structure, and at least a portion of the second side wall 514 is constructed with a serrated structure.

[0088] The first connecting wall 511 can be used to connect to the first surface of the first annular frame 400, and the second connecting wall 513 can be used to connect to the heat exchange part 300. The first connecting wall 511 and the second connecting wall 513 enable surface contact between the magnetic seal 500 and the first annular frame 400 and the heat exchange part 300, thereby increasing the sealing area and improving the sealing effect. The first sidewall 512 and the second sidewall 514 are at least partially constructed with a serrated structure, making them compressible and easily compressible. Of course, in some optional embodiments, the first sidewall 512 and the second sidewall 514 can also be constructed with arcuate surfaces, which also makes them easier to compress to a certain extent.

[0089] In some alternative implementations, such as Figure 1As shown, the magnetic seal 500 includes a first part 530, a second part 540, a third part 550, and a fourth part 560. The first part 530, the second part 540, the third part 550, and the fourth part 560 together define an annular member arranged around the insertion port 401. The first part 530, the second part 540, the third part 550, and the fourth part 560 each include an outer sleeve 510 and a magnetic element 520.

[0090] The magnetic sealing element 500 is formed by sequentially splicing the first part 530, the second part 540, the third part 550 and the fourth part 560. This arrangement makes it easier to fix the magnetic sealing element 500 on the first annular frame 400 or the heat exchange part 300. At the same time, it also allows the magnetic sealing element 500 to be set around the openings 110 on different cabinet doors 100.

[0091] After the cabinet door 100 is closed on the cabinet body 200, in order to improve the sealing between the cabinet door 100 and the cabinet body 200, in some optional embodiments, the sealing structure 30 further includes a second seal 700, which is adapted to seal the gap between the cabinet door 100 and the cabinet body 200.

[0092] It should be noted that the second sealing element 700 can be fixed to the cabinet door 100 and seal the gap between the cabinet door 100 and the cabinet body 200 by pressing it against the cabinet body 200; the second sealing element 700 can also be fixed to the cabinet body 200 and seal the gap between the cabinet doors 100 by pressing it against the cabinet doors. This disclosure does not impose any specific restrictions on this.

[0093] In one optional embodiment provided in this disclosure, the second seal 700 is fixed to the cabinet 200.

[0094] To ensure smooth closing of the cabinet door 100, in some optional embodiments, both the magnetic seal 500 and the second seal 700 are constructed to be compressible, with the clamping stiffness of the magnetic seal 500 being less than that of the second seal 700. Clamping stiffness refers to the amount of deformation of an object under a unit force. Clamping stiffness can be obtained using the formula F = KX, where K is the clamping stiffness, F is the force applied to the object, and X is the amount of deformation of the object under pressure. Under the same conditions, for different objects subjected to the same magnitude of force F, the object with a larger clamping stiffness K will produce a smaller deformation X.

[0095] Furthermore, it should be noted that under the same force F, the clamping stiffness of an object can be adjusted by changing its shape and material. Taking the magnetic seal 500 as an example, the clamping stiffness of the outer sleeve 510 can be adjusted by changing the density of the serrated structure of the first sidewall 512 and the second sidewall 514, adjusting the area of ​​the first connecting surface and the second connecting surface in the outer sleeve 510, and changing the material of the outer sleeve 510.

[0096] To ensure reliable compression of the magnetic seal 500 when the cabinet door 100 is closed, in some alternative embodiments, both the magnetic seal 500 and the second seal 700 are configured to be compressible, with the compression stroke of the magnetic seal 500 being greater than that of the second seal 700.

[0097] To prevent liquid from accumulating in the gap between the first annular frame 400 and the heat exchange section 300, in some alternative embodiments, such as Figure 8 As shown, a drain outlet 440 is provided at the lower end of the first annular frame 400; the drain outlet 440 is adapted to communicate with the sealing gap, wherein the sealing element is the gap between the first annular frame 400 and the heat exchange part 300.

[0098] The drain outlet 440 can discharge the liquid that enters the gap between the first annular frame 400 and the heat exchange section 300 to the outside of the energy storage cabinet 10, so as to avoid liquid accumulation in the gap.

[0099] It is understood that if the liquid needs to be discharged outside the energy storage cabinet 10, then the outlet end of the drain port 440 faces outward from the energy storage cabinet 10. In addition, in order to achieve dust prevention between the cabinet door 100 and the heat exchange section 300, in some optional embodiments, the inlet end of the drain port 440 may be located on the second annular surface 421 or the third annular surface 431.

[0100] Based on the sealing structure 30 of the energy storage cabinet 10 described above, this disclosure also provides an energy storage cabinet 10 in another aspect. The energy storage cabinet 10 includes a cabinet body 200, a cabinet door 100 movably disposed on the cabinet body 200, and the aforementioned sealing structure 30 of the energy storage cabinet 10. A temperature control device 20 is installed inside the cabinet body 200, and an insertion port 401 is provided on the cabinet body 200. When the cabinet door 100 is in the closed state, the heat exchange part 300 of the temperature control device 20 is inserted into the insertion port 401, and the magnetic sealing member 500 seals the gap between the first annular frame 400 and the heat exchange part 300.

[0101] By installing a temperature control device 20 inside the cabinet 200, the temperature of the internal space of the cabinet 200 can be controlled. When an electric cell assembly is installed inside the cabinet 200, the temperature of the electric cell assembly inside the cabinet 200 can be controlled. In addition, it can avoid the defects of deformation and damage to the cabinet door 100 or the inability to close the cabinet door 100 and the cabinet 200 caused by fixing the temperature control device 20 to the cabinet door 100. The aforementioned magnetic yoke seal can seal the gap between the first sealing block and the heat exchange part 300, thereby sealing the heat exchange part 300 and the first sealing element 600, and thus sealing the cabinet door 100 and the temperature control device 20.

[0102] In some alternative embodiments, the sealing structure 30 includes a first annular frame 400 disposed on the cabinet door 100, the first annular frame 400 forming an insertion port 401 for the heat exchange section 300 to be inserted, the insertion port 401 being positioned opposite to the opening 110; a second annular frame 800 circumferentially surrounding the outer surface of the heat exchange section 300, the second annular frame 800 being adapted to be arranged around the insertion port 401; and a magnetic sealing member 500 adapted to seal the gap between the first annular frame 400 and the second annular frame 800.

[0103] By providing a second annular frame 800 circumferentially around the outer surface of the heat exchange section 300, in cases where the heat exchange section 300 cannot directly cooperate with the magnetic seal 500, the second annular frame 800 can cooperate with the magnetic seal 500 to achieve sealing of the cabinet door 100 and the temperature control device 20.

[0104] It should be noted that the heat exchange part 300 cannot directly cooperate with the magnetic seal 500 in the following situations, including but not limited to: the location of the heat exchange part 300 cannot cooperate with the magnetic seal 500, and the material of the heat exchange part 300 cannot be attracted by the magnetic seal 500.

[0105] Regarding the more specific positional relationship between the first sealing frame 800 and the heat exchange section 300, in some optional embodiments, the first annular frame 800 has a first annular surface 411, a second annular surface 421, and a third annular surface 431 adapted to cooperate with the heat exchange section 300; the first annular surface 411 is opposite to the second annular frame 800, the second annular surface 421 is opposite to the circumferential side surface of the heat exchange section 300, and the third annular surface 431 is opposite to the axial end face of the heat exchange section 300.

[0106] The third annular surface 431 and the end face of the heat exchange section 300 are opposite each other, and the second annular surface 421 is opposite to the circumferential side surface of the heat exchange section 300. Therefore, the orientation of the third gap formed between the third annular surface 431 and the heat exchange section 300 is parallel to the extension direction of the surface where the end face of the heat exchange section 300 is located. External liquid cannot directly enter the third gap at an angle perpendicular to the end face of the radiator, thereby improving the waterproof performance to a certain extent. Furthermore, the second annular surface 421 and the circumferential side surface of the radiator form a second gap, and the first annular surface 411 and the second annular frame 800 form a third gap. Thus, the angle between the first gap and the second gap and the angle between the second gap and the third gap form a generally Z-shaped channel, thereby further preventing liquid from entering the energy storage cabinet 10 and contacting the battery cell assembly through the gap between the first annular frame 400 and the heat exchange section 300.

[0107] Based on the energy storage cabinet 10 described above, this disclosure also provides an energy storage system, which includes a plurality of the above-described energy storage cabinets 10, and the plurality of energy storage cabinets are electrically connected to each other.

[0108] The electrical connection between multiple energy storage cabinets 10 can be a series connection, a parallel connection, or a hybrid series-parallel connection. This disclosure does not impose any specific restrictions on this.

[0109] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and all such simple modifications fall within the protection scope of this disclosure.

[0110] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0111] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
