Description

Technical Field

[0001] This application relates to the field of electrical cabinet equipment technology, and in particular to a cabinet-type equipment and energy storage system. Background Technology

[0002] Currently, cabinet-type equipment, such as energy storage equipment, is mainly used to provide installation space for temperature-controlled devices such as battery packs, and to dissipate heat and cool the battery packs so that they operate within a suitable temperature range, thereby providing stable DC power to the power-consuming end.

[0003] In related technologies, energy storage equipment mainly includes a cabinet door, a cabinet body, a liquid-cooled structure, a battery pack, a piping structure, and a liquid-cooling unit. The liquid-cooling unit is located in the cabinet door, and the liquid-cooled structure is located inside the cabinet body. The liquid-cooling unit is connected to the liquid-cooled structure through the piping structure, supplying a temperature-controlled medium to the liquid-cooled structure. The liquid-cooled structure is in contact with the battery pack, heating or cooling the battery pack through heat exchange. The piping structure has multiple rotary joints at the connection between the cabinet door and the cabinet body. This allows adjacent sections of the piping structure to be retracted during the opening and closing of the cabinet door, preventing the piping structure from being flattened or excessively bent during these processes, thus reducing the probability of damage.

[0004] However, the inventors realized that in actual use, if the cabinet door opens and closes quickly, the adjacent pipe sections are prone to separating from the rotary joint, resulting in leakage of the temperature control medium inside the pipe structure, which affects the normal heating or cooling operation of the battery pack and the operational stability of the battery pack. Utility Model Content

[0005] This application provides one or more embodiments of a cabinet-type device and an energy storage system to solve or at least partially alleviate the problem in the related art that liquid cooling pipelines are prone to leakage when the cabinet door opens and closes too quickly, affecting the operational stability of temperature-controlled devices such as battery packs.

[0008] The housing includes a cabinet body and a cabinet door, the cabinet door being rotatably connected to the cabinet body;

[0010] A liquid cooling structure is installed inside the cabinet and makes thermal conductive contact with the device to be temperature controlled.

[0011] A liquid cooling unit is installed on the cabinet door and is used to provide a temperature control medium;

[0012] Liquid cooling pipeline, wherein the liquid cooling unit is connected to the liquid cooling structure through the liquid cooling pipeline, and the liquid cooling pipeline has a first bend;

[0013] A slide rail assembly includes a slide rail structure and a moving structure. The slide rail structure is installed on the cabinet body, and the moving structure is slidably connected to the slide rail structure. A first bent portion is fixedly connected to the moving structure, and the first bent portion moves along the sliding direction of the slide rail structure via the moving structure. The height of the end of the slide rail structure closer to the cabinet door is lower than the height of the end farther from the cabinet door.

[0014] In some embodiments, the slide rail structure includes a slide rail body with a slide groove, and the moving structure includes a moving rod structure that passes through the slide groove and is used to slide along the extending direction of the slide groove.

[0015] In some embodiments, the slide groove includes a first slide groove and a second slide groove connected in sequence, wherein the first slide groove and the second slide groove are arranged at an angle;

[0016] The first sliding groove is configured to accommodate the moving rod structure when the cabinet door is in the open state; the second sliding groove is configured to accommodate the moving rod structure when the cabinet door is in the closed state.

[0017] In some embodiments, the slide rail body is further provided with a limiting hole, which is disposed at the edge of the second sliding groove;

[0018] The limiting hole is configured such that when the cabinet door is in the closed state, the moving rod structure is engaged with the limiting hole.

[0019] In some embodiments, the slide rail structure further includes a connecting plate, which is arranged at an angle to the slide rail body and is used to connect to the cabinet.

[0020] In some embodiments, the slide rail assembly further includes an adjusting member, the connecting plate is provided with an adjusting hole, the extending direction of the adjusting hole is set at an angle to the sliding direction of the slide rail body, the adjusting member passes through the adjusting hole and is connected to the cabinet, and the slide rail structure is tilted by the adjusting member.

[0021] In some embodiments, the movable rod structure includes a first connector and a second connector, the first connector passing through the groove and connected to the second connector, the first connector being used to slide along the extension direction of the groove.

[0022] In some embodiments, the movable rod structure further includes a slider, which is sleeved on the second connector and positioned above the slide rail body;

[0023] The slider is used to connect to the first bend via a third connector.

[0024] In some embodiments, a gap is provided between the bottom of the first connector and the slide rail body.

[0025] In some embodiments, the movable structure further includes a linkage structure, one end of which is rotatably connected to the cabinet door, and the other end of which is connected to the movable rod structure; the first bent portion is connected to the linkage structure.

[0026] In some embodiments, the liquid cooling pipeline includes a first liquid cooling pipe and a second liquid cooling pipe, one end of the first liquid cooling pipe is used to communicate with the liquid cooling unit, one end of each of the second liquid cooling pipes is respectively connected to one end of the first liquid cooling pipe, and the other end of each of the second liquid cooling pipes is used to communicate with each of the liquid cooling structures respectively; the first liquid cooling pipe has the first bend.

[0027] Compared with related technologies, one or more embodiments of this application include at least one of the following beneficial technical effects:

[0028] The temperature of the device to be controlled in cabinet-type equipment can be adjusted in the following ways. For example, the liquid cooling unit delivers the temperature-controlled medium after temperature adjustment to the liquid cooling structure through the liquid cooling pipeline. Since the device to be controlled is in heat conduction contact with the liquid cooling structure, heat exchange can be generated between the temperature-controlled medium circulating in the liquid cooling structure and the device to be controlled, so as to heat or cool the device to be controlled.

[0029] The liquid cooling unit is installed on the cabinet door, and the liquid cooling structure is installed inside the cabinet. Therefore, the liquid cooling pipes used to connect the liquid cooling unit and the liquid cooling structure will bend as the cabinet door rotates and opens or closes relative to the cabinet body. The connection point of the liquid cooling pipes near the cabinet door and the cabinet body can be defined as the first bend, replacing the rotary joint in the prior art.

[0030] The first bend is fixedly connected to the movable structure to fix the first bend of the liquid cooling pipeline onto the movable structure.

[0031] Because the height of the end of the slide rail structure closest to the cabinet door is lower than the height of the end furthest from the cabinet door, in other words, the slide rail structure is arranged at an angle on the cabinet, resulting in a height difference between the two ends of the slide rail structure. This height difference between the two ends of the slide rail structure can be used to match the height difference of the first bend relative to the slide rail structure when the liquid cooling pipeline is in the opening and closing state. Specifically, when the cabinet door changes from the closed state to the open state relative to the cabinet body, the first bend slides forward and downward along the slide rail structure through the moving structure. The first bend is stretched along with the liquid cooling unit installed on the cabinet door, and the bending angle of the first bend increases. The first bend slides forward and downward along the slide rail structure with the moving structure, which can improve the smoothness of the stretching (or unfolding) of the first bend.

[0032] Because a portion of the piping between the first bend and the liquid cooling structure is higher than another portion of the piping between the first bend and the liquid cooling unit, when the cabinet door changes from an open to a closed state relative to the cabinet body, the liquid cooling unit mounted on the cabinet door pushes the first bend forward, causing the first bend to slide backward and upward along the slide rail structure and retract with the moving structure. The bending angle of the first bend becomes smaller, which reduces the retraction angle of the first bend. In short, the slide rail assembly not only provides support for the first bend of the liquid cooling piping but also guides the stretching or retraction of the first bend, adapting to the opening or closing action of the cabinet door. This effectively prevents the first bend from breaking due to excessive force from the rapid opening and closing speed of the cabinet door, which could lead to leakage of the temperature control medium in the liquid cooling piping. This ensures the normal heating or heat dissipation of the temperature control devices during the opening and closing of the cabinet door, thereby achieving the operational stability of the temperature control devices in the cabinet equipment.

[0033] A second aspect of this application provides an energy storage system, which adopts the following technical solution:

[0034] An energy storage system comprising a cabinet-type device as described above.

[0035] Therefore, since energy storage systems include cabinet-type equipment, they possess at least all the technical effects of cabinet-type equipment, which will not be elaborated further here. Attached Figure Description

[0058] Figure 1 This is one of the partial schematic diagrams of an energy storage device according to some embodiments of this application. Figure 2 for Figure 1 Enlarged view of part A in the middle.

[0059] One or more embodiments of this application disclose a cabinet-type device. (See also...) Figure 1 and Figure 2 The cabinet-type equipment includes:

[0060] The housing includes a cabinet body 310 and a cabinet door 300, wherein the cabinet door 300 is rotatably connected to the cabinet body 310;

[0061] A temperature control device is to be installed inside the cabinet 310;

[0062] A liquid cooling structure is installed inside the cabinet 310 and is in thermal conductive contact with the temperature control device.

[0063] A liquid cooling unit 320 is installed on the cabinet door 300 and is used to provide a temperature control medium.

[0064] Liquid cooling pipeline 100, the liquid cooling unit 320 is connected to the liquid cooling structure through the liquid cooling pipeline 100, the liquid cooling pipeline 100 has a first bend 111;

[0065] The slide rail assembly 200 includes a slide rail structure 210 and a moving structure 220. The slide rail structure 210 is used to install on the cabinet 310 of the energy storage device. The moving structure 220 is slidably connected to the slide rail structure 210. The first bent portion 111 is fixedly connected to the moving structure 220 and moves along the sliding direction of the slide rail structure 210 through the moving structure 220. The height of the end of the slide rail structure 210 near the cabinet door 300 of the energy storage device is lower than the height of the end away from the cabinet door 300.

[0066] In at least one embodiment, one end of the cabinet door 300 can be rotatably connected to the cabinet body 310 via a rotating component (e.g., a hinge), and the other end of the cabinet body 310 can be snapped together with the cabinet body 310 via a snap-fit ​​mechanism, so that the cabinet door 300 can rotate relative to the cabinet body 310.

[0067] Temperature control devices can be understood as electronic devices installed inside the cabinet that require temperature regulation, such as battery packs, switching devices, and control devices.

[0068] The liquid cooling structure can be a liquid cooling plate, which has a flow channel cavity for the circulation of temperature-controlled medium.

[0069] The 320 liquid-cooled unit can be a liquid-cooled air conditioner.

[0070] The liquid cooling unit 320 can be installed on the outer or inner wall of the cabinet door 300, and the liquid cooling structure can be installed inside the cabinet 310. The liquid cooling structure can contact the device to be temperature controlled, such as a battery pack. The liquid cooling pipeline 100 can serve as a connecting pipeline between the liquid cooling unit 320 and the liquid cooling structure, so that the liquid cooling unit 320 can deliver the temperature-controlled medium after temperature adjustment to the liquid cooling structure through the liquid cooling pipeline 100, and circulate between the liquid cooling structure and the liquid cooling unit 320 to adjust the temperature of the device to be temperature controlled, such as by heating or cooling.

[0071] The slide rail structure 210 can be fixedly installed on the inner side wall of the cabinet 310, with one end of the slide rail structure 210 facing the inside of the cabinet 310 and the other end facing the cabinet door 300. If the cabinet door 300 is defined to be located at the front end of the cabinet 310, then the height of the end of the slide rail structure 210 close to the cabinet door 300 of the energy storage device is lower than the height of the end far from the cabinet door 300. This can be understood as the front end of the slide rail structure 210 being lower than the rear end of the slide rail structure 210.

[0072] The first bent portion 111 can be fixedly connected to the movable structure 220, so that during the opening and closing of the cabinet door 300 relative to the cabinet body 310, the first bent portion 111 can slide relative to the slide rail structure 210 via the movable structure 220.

[0073] Figure 1 and Figure 2 In the middle, the cabinet door 300 switches from the closed state to the open state. Therefore, in the open state, the first bend 111 is represented by a solid line, and in the closed state, the first bend 111 is represented by a dashed line.

[0074] Figure 4 In the middle, when cabinet door 300 is in the closed state, the first bend 111 is represented by a solid line.

[0075] The temperature of the device to be controlled in the cabinet equipment can be adjusted in the following way: for example, the liquid chiller 320 delivers the temperature-controlled medium after temperature adjustment to the liquid cooling structure through the liquid cooling pipeline 100. Since the device to be controlled is in heat conduction contact with the liquid cooling structure, the temperature-controlled medium with a certain temperature circulating in the liquid cooling structure generates heat exchange with the device to be controlled, so as to heat or cool the device to be controlled.

[0076] The liquid cooling unit 320 is installed on the cabinet door 300, and the liquid cooling structure is installed inside the cabinet 310. Therefore, the liquid cooling pipe 100 used to connect the liquid cooling unit 320 and the liquid cooling structure will bend as the cabinet door 300 rotates and opens or closes relative to the cabinet 310. The connection point of the liquid cooling pipe 100 near the cabinet door 300 and the cabinet 310 can be defined as the first bend 111, and replaces the rotary joint in the prior art.

[0077] The first bend 111 is fixedly connected to the movable structure 220 to fix the first bend 111 of the liquid cooling pipeline 100 onto the movable structure 220.

[0078] Since the height of the end of the slide rail structure 210 closer to the cabinet door 300 is lower than the height of the end farther from the cabinet door 300, in other words, the slide rail structure 210 is inclinedly arranged on the cabinet body 310, so that there is a height difference between the two ends of the slide rail structure 210. This height difference between the two ends of the slide rail structure 210 can be used to match the height difference of the movement of the first bending part 111 relative to the slide rail structure when the liquid cooling pipe 100 is in the opening and closing state. Specifically, when the cabinet door 300 changes from the closed state to the open state relative to the cabinet body 310, the first bending part 111 slides forward and downward along the slide rail structure 210 through the moving structure 220. The first bending part 111 is stretched along the liquid cooling unit 320 installed on the cabinet door 300, the bending angle of the first bending part 111 increases, and the first bending part 111 slides forward and downward along the slide rail structure 210 with the moving structure 220, which can improve the smoothness of the stretching (or unfolding) of the first bending part.

[0079] Because a portion of the piping between the first bend and the liquid cooling structure is higher than another portion of the piping between the first bend and the liquid cooling unit, when the cabinet door 300 changes from an open state to a closed state relative to the cabinet body 310, the liquid cooling unit 320 mounted on the cabinet door 300 pushes the first bend 111 forward, causing the first bend 111 to slide backward and upward along the slide rail structure 210 with the moving structure 220 and retract. The bending angle of the first bend 111 becomes smaller, which reduces the retraction angle of the first bend 111. In short, through the slide rail assembly 200... The first bend 111 of the liquid cooling pipeline 100 not only provides support but also guides the stretching or retraction of the first bend 111, adapting to the opening or closing action of the cabinet door 300. This effectively prevents the first bend 111 from breaking due to excessive force during the opening and closing speed of the cabinet door 300, which would lead to leakage of the temperature control medium in the liquid cooling pipeline 100. This ensures the normal heating or heat dissipation of the temperature control device during the opening and closing of the cabinet door 300, thereby achieving the operational stability of the temperature control device in the cabinet equipment.

[0080] Figure 3This is an exploded view of a slide rail assembly 200 according to some embodiments of this application.

[0081] In some embodiments, combined with Figure 3 As shown, the slide rail structure 210 includes a slide rail body 211, the slide rail body 211 is provided with a slide groove 2110, and the moving structure 220 includes a moving rod structure 221, the moving rod structure 221 passes through the slide groove 2110 and is used to slide along the extending direction of the slide groove 2110.

[0082] In at least one embodiment, the slide rail body 211 can be directly fixed to the inner wall of the cabinet 310, or it can be fixed to the inner wall of the cabinet 310 by other components. The slide rail body 211 is provided with a slide groove 2110, which can serve as the sliding trajectory of the moving structure 220 relative to the slide rail structure 210.

[0083] The first bent portion 111 can be fixedly connected to the movable rod structure 221, so that the first bent portion 111 can slide in the slide groove 2110 with the movable rod structure 221.

[0084] Since the moving rod structure 221 passes through the slide groove 2110 of the slide rail body 211, and the first bent part 111 can slide with the moving rod structure 221 in the slide groove 2110 of the slide rail body 211, it is suitable for the stretching and retraction of the first bent part 111 of the liquid cooling pipe 100 during the opening and closing of the cabinet door 300.

[0085] Figure 4 This is a second partial schematic diagram of an energy storage device according to some embodiments of this application. Figure 5 for Figure 4 Enlarged view of section B.

[0086] In some embodiments, combined with Figures 3 to 5 As shown, the sliding groove 2110 includes a first sliding groove 2111 and a second sliding groove 2112 connected in sequence, and the first sliding groove 2111 and the second sliding groove 2112 are arranged at an angle.

[0087] The first sliding groove 2111 is configured to accommodate the moving rod structure 221 when the cabinet door 300 is in the open state; the second sliding groove 2112 is configured to accommodate the moving rod structure 221 when the cabinet door 300 is in the closed state.

[0088] In at least one embodiment, the first sliding groove 2111 is connected to the second sliding groove 2112, and the two can form an L-shaped sliding groove; correspondingly, the top surface of the slide rail body 211 can be L-shaped, so the slide rail body 211 can be an L-shaped straight plate structure.

[0089] When the cabinet door 300 switches from the closed state to the open state, the first bent portion 111 can move from the second sliding groove 2112 to the first sliding groove 2111 along with the moving rod structure 221. The first bent portion 111 is stretched and the bending angle of the first bent portion 111 becomes larger. Therefore, when the cabinet door 300 is in the open state, the moving rod structure 221 is in the first sliding groove 2111. When the cabinet door 300 switches from the open state to the closed state, the first bent portion 111 can move from the first sliding groove 2111 to the second sliding groove 2112 along with the moving rod structure 221. The first bent portion 111 is retracted and the bending angle of the first bent portion 111 becomes smaller. Therefore, when the cabinet door 300 is in the closed state, the moving rod structure 221 is in the second sliding groove 2112.

[0090] In some embodiments, combined with Figures 3 to 5 As shown, the slide rail body 211 is also provided with a limiting hole 2113, which is located at the edge of the second sliding groove 2112;

[0091] The limiting hole 2113 is configured such that when the cabinet door 300 is in the closed state, the moving rod structure 221 is engaged with the limiting hole 2113.

[0092] In at least one embodiment, the limiting hole 2113 may be disposed on the edge of the second sliding groove 2112 near the edge of the first sliding groove 2111. The limiting hole 2113 may be an arc-shaped hole structure disposed on the edge of the second sliding groove 2112.

[0093] When the cabinet door 300 is in the closed state, the moving rod structure 221 is in or engaged with the limiting hole 2113, so that the moving rod structure 221 is engaged with the limiting hole 2113 to restrict the first bent part 111 from continuing to move along the second sliding groove 2112, thereby realizing the constraint of the first bent part 111 by the cabinet door 300 in the closed state.

[0094] In some embodiments, combined with Figure 3 As shown, the slide rail structure 210 also includes a connecting plate 212, which is set at an angle to the slide rail body 211, and is used to connect to the cabinet 310.

[0095] In at least one embodiment, the connecting plate 212 may be set at an angle to the side of the slide rail body 211, so that the slide rail structure 210 has an L-shaped cross-section in the vertical direction.

[0096] The connecting plate 212 and the slide rail body 211 can be constructed as an integral structure, thereby improving the mechanical strength of the slide rail structure 210.

[0097] The connecting plate 212 can be set vertically, and the slide rail body 211 can be fixedly connected to the side wall of the cabinet 310 through the connecting plate 212, so as to increase the connection area with the cabinet 310 through the connecting plate 212, and correspondingly improve the connection stability between the slide rail structure 210 and the cabinet 310.

[0098] Furthermore, the connecting plate 212 can be directly fixedly connected to the side wall of the cabinet 310, or the connecting plate 212 can be connected to the side wall of the cabinet 310 through other structures such as fasteners 400 (in combination). Figure 3 As shown, the fastener 400 can be fixed to the side wall of the cabinet 310 by welding, bolt fasteners, or other methods.

[0099] In some embodiments, combined with Figure 3 As shown, the slide rail assembly 200 also includes an adjusting member 230. The connecting plate 212 is provided with an adjusting hole 2120. The extending direction of the adjusting hole 2120 is set at an angle to the sliding direction of the slide rail body 211. The adjusting member 230 passes through the adjusting hole 2120 and is connected to the cabinet 310. The slide rail structure 210 is tilted by the adjusting member 230.

[0100] In at least one embodiment, the adjusting member 230 may be a bolt fastener. The adjusting hole 2120 may be a slotted hole or a strip hole.

[0101] The fact that the extension direction of the adjustment hole 2120 can be set at an angle to the sliding direction of the slide rail body 211 can be understood as the adjustment hole 2120 being arranged vertically, or the adjustment hole 2120 being arranged at an angle to the sliding direction of the slide rail body 211, for example, an acute angle or an obtuse angle.

[0102] The connecting plate 212 can be provided with at least two adjustment holes 2120 arranged at intervals. When the connecting plate 212 is fixed to the side wall of the cabinet, two adjustment pieces 230 can be inserted through two of the adjustment holes 2120 and the side wall of the cabinet.

[0103] Since the extension direction of the adjustment hole 2120 is set at an angle to the sliding direction of the slide rail body 211, at least one end of the slide rail structure 210 can move up and down relative to the side wall of the cabinet 310 to adjust its position, thereby adjusting the tilt angle of the slide rail structure 210. After the position is adjusted, the adjustment member 230 passes through the adjustment hole 2120 of the connecting plate 212 and is connected to the side wall of the cabinet 310 (or the fixing member 400) to achieve the fixing operation of the slide rail structure 210 after the tilt angle is adjusted. In this way, the tilt angle of the slide rail structure 210 is adjusted by the adjustment member 230, thereby absorbing the tolerance of the distance between the first bending part 111 and the slide groove 2110, and avoiding the first bending part 111 from being deformed by the force of the pull.

[0104] Figure 6 This is an exploded view of the movable rod structure 221 according to some embodiments of this application. Figure 7 This is a schematic diagram of a slide rail assembly 200 according to some embodiments of this application.

[0105] In some embodiments, combined with Figure 3 , Figure 6 and Figure 7 As shown, the movable rod structure 221 includes a first connector 2211 and a second connector 2212. The first connector 2211 passes through the slide groove 2110 and is connected to the second connector 2212. The first connector 2211 is used to slide along the extension direction of the slide groove 2110.

[0106] In at least one embodiment, the first connector 2211 and the second connector 2212 can be arranged along the axial direction of the movable rod structure 221, and the first connector 2211 passes through the slide groove 2110 and is connected to the second connector 2212, so as to realize that the movable rod structure 221 passes through the slide groove 2110. The first connector 2211 can drive the first bent part to slide along the extension direction of the slide groove 2110 to adapt to the stretching and retraction of the liquid cooling pipeline during the opening and closing of the cabinet door.

[0107] The first connecting member 2211 and the second connecting member 2212 can be connected in the following way: for example, the first connecting member 2211 has an internal thread, and the second connecting member 2212 has an external thread. The second connecting member 2212 is connected to the internal thread through the external thread to achieve a fixed connection between the first connecting member 2211 and the second connecting member 2212. The second connecting member 2212 can be a screw structure with external threads, and the first connecting member 2211 can be a nut structure with internal threads.

[0108] The first connector 2211 can be a nut structure with a variable diameter, so that after part of the first connector 2211 passes through the slide groove 2110, the first connector 2211 will not detach from the slide groove 2110 of the slide rail body 211. This variable diameter structure can be understood as the upper diameter of the first connector 2211 being smaller than the diameter of other parts below the upper end.

[0109] In some embodiments, combined with Figure 6 and Figure 7 As shown, the movable rod structure 221 also includes a slider 2213, which is sleeved on the second connecting member 2212 and is located above the slide rail body 211;

[0110] The slider 2213 is used to connect to the first bent portion 111 via the third connector 223.

[0111] In at least one embodiment, the slider 2213 may be a pad structure, and the slider 2213 may be sleeved on the outside of the second connector 2212.

[0112] The third connecting member 223 can adopt a clamp structure, that is, the clamp structure is sleeved on the first bent part 111, and the clamp structure and the slider 2213 can be fixedly connected by welding or other methods, so that the first bent part 111 can be fixedly connected to the slider 2213 through the third connecting member 223, so that the first bent part 111 can slide along the slide groove 2110 through the slider 2213 and the first connecting member 2211, ensuring the smooth movement of the first bent part 111 relative to the slide groove 2110 of the slide rail body 211. The slider 2213 adopts a flat washer structure, and the overall structure has no protrusions. During the opening and closing of the door, the slider 2213 always moves on the upper part of the slide rail body 211, without interfering with other internal components, saving internal design space.

[0113] In some embodiments, combined with Figure 7 As shown, there is a gap between the bottom of the first connector 2211 and the slide rail body 211.

[0114] In at least one embodiment, a gap is provided between the bottom of the first connector 2211 and the slide rail body 211. This can be understood as the smaller diameter portion of the first connector 2211 passing through the slide groove 2110, the larger diameter portion of the first connector 2211 being located below the slide rail body 211, and the first connector 2211 having a certain height, such that there is a gap between the bottom end of the first connector 2211 and the slide rail body 211.

[0115] When the first connector 2211 is connected to the second connector 2212 that passes through the slider 2213, there is a gap between the bottom end of the first connector 2211 and the slide rail body 211 along the height direction. This gap can also be used to absorb the tolerance of the distance between the first bend 111 and the slide rail body 211, so as to avoid the part of the liquid cooling pipe 100 close to the liquid cooling unit 320 being subjected to force and deformation.

[0116] Figure 8 This is a third partial schematic diagram of an energy storage device according to some embodiments of this application. Figure 11 This is a partial schematic diagram of an energy storage device according to some embodiments of this application.

[0117] In some embodiments, combined with Figure 8 As shown, the movable structure 220 also includes a connecting rod structure 222, one end of which is rotatably connected to the cabinet door 300, and the other end of which is connected to the movable rod structure 221; the first bent portion 111 is connected to the connecting rod structure 222.

[0118] In at least one embodiment, one end of the linkage structure 222, for example the front end, can be directly rotatably connected to the cabinet door 300 via a rotating member, or rotatably connected to the mounting bracket 330 fixed on the cabinet door 300 via a rotating member; wherein, the rotating member can be a pin structure, a hinge structure, etc.

[0119] The other end of the linkage structure 222, such as the rear end, can be rotatably connected to the movable rod structure 221.

[0120] The linkage structure 222 can move along the slide groove 2110 in the slide rail body 211. The first bend 111 of the liquid cooling pipe 100 is fixed to the rear end of the linkage structure 222. During the opening and closing of the cabinet door 300, the mounting bracket 330 on the cabinet door 300 drives the linkage structure 222 to move in the slide groove 2110 via the moving rod structure 221, thereby pulling the first bend 111 of the liquid cooling pipe 100 to move, thereby constraining and limiting the liquid cooling pipe 100.

[0121] Figure 9 This is a schematic diagram of a liquid cooling pipeline 100 according to some embodiments of this application.

[0122] In some embodiments, combined with Figure 9 As shown, the liquid cooling pipeline 100 includes a first liquid cooling pipe 110 and a second liquid cooling pipe 120. One end of the first liquid cooling pipe 110 is used to communicate with the liquid cooling unit 320, one end of each of the second liquid cooling pipes 120 is respectively connected to one end of the first liquid cooling pipe 110, and the other end of each of the second liquid cooling pipes 120 is used to communicate with each of the liquid cooling structures respectively; the first liquid cooling pipe 110 has the first bend 111.

[0123] In at least one embodiment, since the energy storage device includes battery clusters, each battery cluster includes multiple battery packs arranged vertically, each battery pack is configured with at least one liquid cooling structure, each liquid cooling structure may be configured with two second liquid cooling pipes 120 (a tertiary liquid inlet pipe and a tertiary liquid return pipe, respectively); each battery cluster may be configured with two first liquid cooling pipes 110 (a secondary liquid inlet pipe and a secondary liquid return pipe, respectively).

[0124] The temperature control medium can flow in the following manner: for example, the temperature control medium is output from the outlet of the liquid cooler unit 320, flows along the secondary inlet pipe and enters the corresponding liquid cooling structure through each tertiary inlet pipe. The temperature control medium circulating in the liquid cooling structure can heat or cool the battery pack. Then, the temperature control medium flows out of the liquid cooling structure, enters the secondary return pipe through the tertiary return pipe for convergence, and finally flows back to the liquid cooler unit 320. This process is continuously circulated to achieve continuous heating or cooling of the battery pack.

[0125] Figure 10 This is a fourth partial schematic diagram of an energy storage device according to some embodiments of this application.

[0126] Combination Figure 10 As shown, the first liquid cooling pipe 110 can also be designed with the following bending angles. For example, the first liquid cooling pipe 110 also has a second bending portion 112 and a third bending portion 113. The part of the liquid cooling pipe 100 that is connected to the moving structure 220 can be defined as the first bending portion 111. The second bending portion 112 can be located at the connection between the cabinet door 300 and the cabinet body 310, and the second bending portion 112 is located between the first bending portion 111 and the liquid cooling unit 320. The third bending portion 113 is located between the first bending portion 111 and the second liquid cooling pipe 120.

[0127] When the cabinet door 300 is closed, the three bends of the first liquid cooling pipe 110 are indicated by solid lines. At this time, the bending angle of the second bend 112 is 87.4° and the arc length is 161.6mm, the bending angle of the first bend 111 is 103.3° and the arc length is 134.3mm, and the bending angle of the third bend 113 is 90.9° and the arc length is 93mm.

[0128] When the cabinet door 300 switches from the closed state to the open state, the three bends of the first liquid cooling pipe 110 are indicated by dashed lines. The angle of the second bend 112 is 141.39° and the arc length is 70mm. The bending angle of the first bend 111 is 104.42° and the arc length is 70.5mm. The angle of the third bend 113 is 111.3° and the arc length is 120mm.

[0129] In this design, the first bend 111 and the second bend 112 have increased bending angles and shorter arc lengths when the cabinet door 300 is open. The reduced arc length corresponds to the displacement of the first liquid cooling pipe 110 with the liquid cooling unit. The third bend 113 has increased bending angles and arc lengths. The increased angle of the third bend 113 is used to change the forward angle of the first liquid cooling pipe 110, so that the first liquid cooling pipe 110 travels along the second sliding groove 2112. The increased arc length of the third bend 113 is the difference in length traveled along the second sliding groove 2112 when the cabinet door 300 is open and along the first sliding groove 2111 when the door is closed. Therefore, the storage process of the liquid cooling pipe 100 changes the height and front-back lengths of the first bend 111 by changing the bending angle of the first liquid cooling pipe 110, thus adapting to different states of the first liquid cooling pipe 110 when the door is open and closed.

[0130] One or more embodiments of this application also disclose an energy storage system. The energy storage system includes the cabinet-type device described in the above embodiments.

[0131] In some embodiments, if the cabinet-type equipment is an energy storage battery cabinet in an energy storage system, the energy storage system may also include a converter cabinet (i.e., a PCS cabinet). For example, the input terminal of the converter cabinet may be electrically connected to the power grid, and the output terminal of the converter cabinet may be electrically connected to the cabinet-type equipment, so as to convert the AC power of the power grid into DC power through the converter cabinet to charge the temperature control devices such as battery packs in the cabinet-type equipment.

[0132] The energy storage system may also include a battery management system cabinet (BMS cabinet), which may include a BMS main controller, communication module, data acquisition unit, protection relays, etc., and is mainly used to monitor the battery voltage, current, temperature, insulation status, etc. of the battery pack. The energy storage system may also include other cabinets that are electrically connected to the cabinet-type equipment, which will not be described in detail here.
