Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling units, in particular to a cabinet-type device and an energy storage system. Background Art

[0002] Air cooling is difficult to meet the energy storage industry's heat dissipation needs for high energy density devices, while liquid cooling is widely used in energy storage systems due to its advantages such as high thermal conductivity, uniform heat dissipation and low energy consumption.

[0003] In order to reduce the floor space, liquid cooling has gradually evolved to door-mounted liquid cooling units. The liquid cooling unit on the cabinet door and the liquid cooling module in the cabinet are connected through a pipeline structure, so that the coolant flows between the liquid cooling unit and the liquid cooling module. However, the coolant flow at the pipeline structure may be blocked, and the service life of the pipeline is short. Utility Model Content

[0004] The purpose of the present application is to provide a cabinet-type device and an energy storage system for improving the circulation of coolant in a pipeline structure and at the same time increasing the service life of the pipeline structure.

[0005] In a first aspect of an embodiment of the present application, a cabinet-type device is provided, comprising a cabinet body, a cabinet door, a liquid cooling unit, a liquid cooling module, and a pipeline structure. The cabinet body has a receiving slot, the liquid cooling module is arranged in the receiving slot, the cabinet door is arranged at the slot position of the receiving slot, and the cabinet door is rotatably or slidably connected to the cabinet body. The pipeline structure is connected to the cabinet door, the liquid cooling unit is connected to the liquid cooling module through the pipeline structure, and the pipeline structure is slidably connected to the cabinet body in a direction toward or away from the bottom of the receiving slot.

[0006] The cabinet door is arranged at the slot position of the cabinet-type equipment receiving slot, so that the slot can be covered to protect the liquid cooling module in the receiving slot. Through the pipeline structure, the coolant can flow between the liquid cooling unit and the liquid cooling module. In the related art, the pipeline structure is fixed on the side wall of the cabinet. When the cabinet door is closed, the distance between the liquid cooling unit and the side wall of the cabinet is reduced, and a part of the pipeline structure will be compressed, making the pipeline structure prone to flattening, bending, etc., thereby hindering the circulation of the coolant in the pipeline structure and reducing the heat dissipation effect of the liquid cooling module. Even when flattened and bent multiple times, the pipeline structure may be damaged, reducing the service life of the pipeline structure.

[0007] In the cabinet-type equipment provided by the present application, when the cabinet door is opened, the cabinet door drives the pipeline structure connected to the cabinet door to slide in the direction away from the bottom of the receiving groove. When the cabinet door is closed, the cabinet door drives the pipeline structure connected to the cabinet door to slide in the direction toward the bottom of the receiving groove. In this way, when the cabinet door is closed, the distance between the end of the pipeline structure away from the cabinet door and the cabinet door increases, avoiding the pipeline structure from being severely squeezed and deformed due to too small a spacing, and the occurrence of flattening and bending, thereby ensuring the circulation of the coolant in the pipeline structure. At the same time, the occurrence of damage to the pipeline structure when it is flattened and bent multiple times is reduced; it also reduces the situation that the pipeline structure is scratched with the cabinet body after bending, preventing the pipeline structure or the cabinet body from being worn due to multiple scratches, thereby improving the service life of the pipeline structure and the cabinet body. In summary, the cabinet-type equipment provided by the present application can improve the circulation of the coolant in the pipeline structure. At the same time, the service life of the pipeline structure is improved. In addition, after the pipeline structure slides toward the bottom of the accommodating groove, the resistance to the closing of the cabinet door caused by the deformation and bending of the pipeline structure is reduced, which facilitates the closing of the cabinet door.

[0008] In some embodiments of the present application, the cabinet device includes at least one sliding mechanism, the sliding mechanism includes a first sliding member and a second sliding member, the first sliding member is arranged on the side wall of the receiving tank, and the second sliding member is arranged on the pipeline structure. The first sliding member and the second sliding member are slidably connected in the direction toward or away from the bottom of the receiving tank. At this time, when the cabinet door is closed, the pipeline structure is subjected to a force in the direction toward the bottom of the receiving tank, thereby driving the second sliding member arranged on the pipeline structure to slide relative to the first sliding member in the direction toward the bottom of the receiving tank, and the first sliding member is arranged on the side wall of the receiving tank, that is, the pipeline structure and the second sliding member can slide relative to the side wall of the receiving tank in the direction toward the bottom of the receiving tank, thereby realizing the sliding connection between the pipeline structure and the side wall of the receiving tank. In addition, after the pipeline structure is filled with coolant, the weight of the pipeline structure and the coolant inside is large, and under the action of gravity, the connection between the pipeline structure and the liquid cooling unit may be pulled, causing the connection to deform or even disconnect. In an embodiment of the present application, in a direction parallel to the bottom of the receiving tank, the second sliding member can limit the pipeline structure, so that the pipeline structure slides along with the second sliding member on the first sliding member arranged on the side wall of the receiving tank, that is, moves in a direction toward or away from the bottom of the receiving tank, thereby avoiding the pipeline structure from moving in other directions and preventing the pipeline structure from pulling the connection between the pipeline structure and the liquid cooling unit due to gravity and other effects.

[0009] In some embodiments of the present application, the first sliding member is a groove formed on the side wall of the receiving groove, the groove extends in a direction toward or away from the bottom of the receiving groove, and the second sliding member is a protrusion slidably disposed in the groove, and the protrusion is connected to the pipeline structure. After the groove is formed on the side wall of the cabinet to form a slide rail as the first sliding member and the protrusion is disposed in the groove, the distance between the pipeline structure and the side wall can be reduced, thereby facilitating the arrangement of other devices on the side of the pipeline structure away from the side wall, so as to improve the space utilization rate in the cabinet.

[0010] In some embodiments of the present application, the receiving tank has a first side wall, and the first side wall intersects with the bottom of the receiving tank. The cabinet door is hinged to the first side wall of the receiving tank, the liquid cooling unit is arranged on the side of the cabinet door facing the receiving tank, and the first sliding member is arranged on the first side wall. At this time, after the cabinet door is hinged to the first side wall of the receiving tank, when the cabinet door rotates relative to the first side wall, the first sliding member is arranged on the first side wall, and the hinge position of the first sliding member and the cabinet door and the first side wall is closer to each other than the other side walls arranged on the receiving tank. During the process of closing or opening the cabinet door, the required distance to drive the pipeline structure to move is smaller. In addition, the distance between the side of the liquid cooling unit facing the first side wall and the first sliding member arranged on the first side wall is smaller, so that after the pipeline structure is slidably connected to the first sliding member through the second sliding member, the length of the pipeline structure is shorter. This makes the total length of the pipeline structure smaller, and the pipeline structure is not easy to bend when the cabinet door is closed.

[0011] In some embodiments of the present application, the pipeline structure is connected to the side of the liquid cooling unit facing the first side wall. After the cabinet door is hinged to the first side wall of the receiving groove, when the cabinet door rotates relative to the first side wall, the closer the liquid cooling unit disposed on the cabinet door is to the hinge between the cabinet door and the first side wall, the smaller the displacement distance, that is, the displacement distance of the liquid cooling unit toward the side of the first side wall is the smallest. After the pipeline structure is connected to the side of the liquid cooling unit facing the first side wall, during the process of opening or closing the cabinet door, the displacement distance of one end of the pipeline structure toward the liquid cooling unit is smaller, and the pipeline structure is not easy to bend.

[0012] In some embodiments of the present application, the cabinet equipment includes N liquid cooling modules and N sliding mechanisms. The vertical projection of a first sliding member on the first side wall is located within the vertical projection of a liquid cooling module on the first side wall. Alternatively, along the stacking direction of the liquid cooling module, the vertical projection of the first sliding member on the first side wall and the vertical projection of the liquid cooling module on the first side wall are spaced apart. Wherein, N≥1, and N is an integer. Exemplarily, N is 1, 2, 3, 4, 5, 6, etc. At this time, the vertical projections of the first sliding member and the liquid cooling module on the first side wall correspond one-to-one, ensuring that the part of the pipeline structure close to the liquid cooling module can be slidably connected to the first side wall through the sliding mechanism, thereby improving the stability of the sliding connection between the pipeline structure and the first side wall.

[0013] In some other embodiments of the present application, the receiving tank has a second side wall, the cabinet door is hinged to the first side wall of the receiving tank, and the first sliding member is arranged on the second side wall. The second side wall intersects with the first side wall. At this time, when the cabinet door is opened or closed, the pipeline structure and the second sliding member are slidably connected relative to the first sliding member arranged on the second side wall, that is, the pipeline structure and the second sliding member can slide relative to the side wall of the receiving tank in a direction toward the bottom of the receiving tank, thereby realizing a sliding connection between the pipeline structure and the cabinet body.

[0014] In some other embodiments of the present application, the cabinet door is slidably connected to the cabinet body in a direction toward or away from the bottom of the receiving groove. When the cabinet door slides relative to the receiving groove, the cabinet door is opened or closed. The cabinet door and the pipeline structure both slide relative to the cabinet body in a direction toward or away from the bottom of the receiving groove, that is, when the cabinet door is closed, when the cabinet door slides in the direction toward the bottom of the receiving groove, the pipeline structure also slides in the direction toward the bottom of the receiving groove, thereby reducing the degree of compression and deformation of the pipeline structure caused by the closing of the cabinet door, and preventing the circulation of the coolant from being affected by the flattening or bending of the pipeline structure.

[0015] In some embodiments of the present application, the pipeline structure includes a first pipeline and a second pipeline that are connected and communicated in sequence, the first pipeline is connected to the cabinet door, the end of the first pipeline away from the second pipeline is communicated with the liquid cooling unit, the end of the second pipeline away from the first pipeline is communicated with the liquid cooling module, and the second pipeline is connected to the second sliding member. When the cabinet door is opened, the cabinet door drives the liquid cooling unit and the first pipeline connected to the liquid cooling unit to move in a direction away from the bottom of the receiving tank, and then drives the second pipeline connected to the first pipeline to move in a direction toward the cabinet door. At this time, the second sliding member connected to the second pipeline will slide on the first sliding member in a direction toward the cabinet door. When the cabinet door is closed, the cabinet door drives the liquid cooling unit and the first pipeline connected to the liquid cooling unit to move in a direction toward the bottom of the receiving tank, and then drives the second pipeline connected to the first pipeline to move in a direction away from the cabinet door. At this time, the second sliding member connected to the second pipeline will slide on the first sliding member in a direction away from the cabinet door. In this way, when the cabinet door is opened, the first pipeline and the second pipeline both move toward the cabinet door, that is, toward the liquid cooling unit, to ensure that the first pipeline can be connected to the liquid cooling unit. When the cabinet door is closed, the first pipeline and the second pipeline both move away from the cabinet door, that is, away from the liquid cooling unit, so that the distance between the end of the first pipeline away from the liquid cooling unit and the liquid cooling unit is increased, avoiding the first pipeline from being severely squeezed and deformed due to too small a distance, and being flattened or bent, thereby ensuring the circulation of the coolant in the first pipeline. At the same time, it prevents the first pipeline from being damaged due to multiple bends, thereby increasing the service life of the first pipeline.

[0016] In some embodiments of the present application, the pipeline structure further includes a fixing member, which is arranged along the circumference of the second pipeline and connected to the second pipeline, and the side of the fixing member facing away from the second pipeline is connected to the second sliding member. The second pipeline is connected to the second sliding member through the fixing member, which ensures that the second pipeline can slide on the side wall of the accommodating groove with the second sliding member, while improving the connection stability between the second pipeline and the second sliding member.

[0017] In some embodiments of the present application, the pipeline structure also includes a first rotary joint, the first rotary joint includes a first joint and a second joint that are connected, and the first joint is rotatably connected relative to the second joint along the axis of the second joint. The first joint is coaxially arranged with the first pipeline, and the first joint is connected and connected with the first pipeline. The second joint is coaxially arranged with the second pipeline, and the second joint is connected and connected with the second pipeline. In the related art, after the first pipeline and the second pipeline are connected, when the cabinet door is closed, the distance between the liquid cooling unit and the side wall of the cabinet is reduced, and after the first pipeline is squeezed and deformed, the connection between the first pipeline and the second pipeline is subjected to greater force. Under the action of external force, the sealing of the connection between the first pipeline and the second pipeline may fail. In the cabinet equipment provided by the present application, the first joint and the second joint are rotatably connected along the axis of the second joint, so that the first pipeline connected to the first joint and the second pipeline connected to the second joint can rotate relative to each other. When the cabinet door is opened or closed, the first pipeline is subjected to force, which drives the first joint to rotate relative to the second joint along the axis of the second joint, so as to reduce the deformation degree of the end of the first pipeline close to the second pipeline, thereby reducing the force at the connection between the first pipeline and the second pipeline, preventing the sealing failure at the connection between the first pipeline and the second pipeline due to pulling by external force, and reducing the risk of sealing failure between the first pipeline and the second pipeline.

[0018] In some embodiments of the present application, the pipeline structure also includes a second rotary joint, the second rotary joint includes a third joint and a fourth joint that are connected to each other, and the third joint is rotatably connected relative to the fourth joint along the axis of the fourth joint. The third joint is coaxially arranged with the first pipeline, and the third joint is connected and communicated with the first pipeline. The fourth joint is connected and communicated with the liquid cooling unit. In the related art, after the first pipeline and the liquid cooling unit are connected, when the cabinet door is closed, the distance between the liquid cooling unit and the side wall of the cabinet is reduced, and after the first pipeline is squeezed and deformed, the connection between the first pipeline and the liquid cooling unit is subjected to greater force. Under the action of external force, the seal at the connection between the first pipeline and the liquid cooling unit may fail. In the cabinet equipment provided by the present application, the third joint and the fourth joint are rotatably connected along the axis of the fourth joint, so that the first pipeline connected to the third joint and the liquid cooling unit connected to the fourth joint can rotate relative to each other. When the cabinet door is opened or closed, after the first pipeline is subjected to force, the third joint is driven to rotate relative to the fourth joint along the axis of the fourth joint, so as to reduce the deformation degree of the end of the first pipeline close to the liquid cooling unit, thereby reducing the force at the connection between the first pipeline and the liquid cooling unit, preventing the failure of the seal at the connection between the first pipeline and the liquid cooling unit due to external pulling, and reducing the risk of sealing failure between the first pipeline and the liquid cooling unit.

[0019] In some embodiments of the present application, the first pipeline includes a first liquid inlet pipeline and a first liquid return pipeline both connected to the liquid cooling unit, and the second pipeline includes a second liquid inlet pipeline and a second liquid return pipeline both connected to the liquid cooling module. The second liquid inlet pipeline and the second liquid return pipeline are both connected to the second sliding member. The first liquid inlet pipeline is connected to the second liquid inlet pipeline. The first liquid return pipeline is connected to the second liquid return pipeline. At this time, the liquid cooling unit is connected to the first liquid inlet pipeline, the first liquid inlet pipeline is connected to the second liquid inlet pipeline, the second liquid inlet pipeline is connected to the liquid cooling module, the liquid cooling module is connected to the second liquid return pipeline, the second liquid return pipeline is connected to the first liquid return pipeline, and the first liquid return pipeline is connected to the liquid cooling unit. The coolant can form a cold flow loop between the liquid cooling unit, the first liquid inlet pipeline, the second liquid inlet pipeline, the liquid cooling module, the second liquid return pipeline, and the first liquid return pipeline to complete the continuous heat dissipation in the cabinet.

[0020] In some embodiments of the present application, the pipeline structure further includes: the third pipeline includes a third liquid inlet pipeline and a third liquid return pipeline, both of which are connected to the liquid cooling module. The third liquid inlet pipeline is connected to the second liquid inlet pipeline, and the third liquid return pipeline is connected to the second liquid return pipeline. The third liquid inlet pipeline is respectively connected to the second liquid inlet pipeline and the liquid cooling module to ensure that the coolant in the second liquid inlet pipeline can enter the liquid cooling module; the third liquid return pipeline is respectively connected to the second liquid return pipeline and the liquid cooling module to ensure that the coolant in the liquid cooling module can flow back to the second liquid return pipeline.

[0021] In a second aspect of an embodiment of the present application, an energy storage system is provided, comprising the above-mentioned cabinet-type device, and at least one battery pack arranged in the cabinet-type device. The liquid cooling module is used to dissipate heat from the battery pack. The above-mentioned energy storage system has the same technical effect as the cabinet-type device provided in any of the above-mentioned embodiments, and will not be described in detail here.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0032] In the following, the terms "first", "second", "third", "fourth", etc. are used only for convenience of description and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", "third", "fourth", etc. may explicitly or implicitly include one or more of the feature. In the description of this application, unless otherwise specified, "plurality" means two or more.

Any embodiment or design described as "exemplarily" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" and "for example" is intended to present related concepts in a specific way.

[0035] In the drawings of the embodiments of the present application, components are represented by guide lines with arrows; parts are represented by guide lines only; hollow structures such as cavities and openings are represented by curved guide lines.

[0036] The present application embodiment provides an energy storage system 100. Figure 1 As shown, the energy storage system 100 may include a cabinet device 01 and at least one battery pack 02 disposed in the cabinet device 01 , and the cabinet device 01 is used to accommodate and protect the battery pack 02 .

[0037] Continue as Figure 1 As shown, the energy storage system 100 may further include a power converter 03 electrically connected to the battery pack 02. The power converter 03 may also be disposed in the cabinet device 01. The power converter 03 is used to convert the voltage output by the battery pack 02 into power and output it to the power grid 04 or the load 05, or to convert the voltage output by the external power supply into power and output it to the battery pack 02.

[0038] For example, the energy storage system 100 may be a photovoltaic system, a wind power generation system, a hydropower generation system, a geothermal power generation system, etc.

[0039] The following description will be made by taking the above energy storage system 100 as a photovoltaic system as an example. Figure 1 As shown, the photovoltaic system may further include a photovoltaic module 06. The photovoltaic module 06 converts solar energy into electrical energy and sends it to the battery pack 02 for storage. In addition, the battery pack 02 converts the voltage into power through the power converter 03 and directly transmits it to the load 05, or transmits it to the load 05 through the power grid 04, to provide electrical energy for the operation of the load 05.

[0040] The above embodiment Figure 1 As shown, the energy storage system 100 includes one cabinet device 01, one battery pack 02 and one power converter 03. In other embodiments of the present application, the number of cabinet devices 01, battery packs 02 and power converters 03 may also be other numbers.

[0041] The present application embodiment also provides a communication system 200. Figure 2 As shown, the communication system 200 may include a cabinet device 01 and a communication device 07 disposed in the cabinet device 01 . The cabinet device 01 is used to accommodate and protect the communication device 07 .

[0042] For example, the communication system 200 may be a server, a computer system, a communication room, a data exchange center, a network control room, etc.

[0043] The structure of the above cabinet device 01 is further illustrated below. Figure 3 As shown, the cabinet device 01 may include a cabinet body 11 and a cabinet door 12. The cabinet body 11 has a receiving slot 111, and the cabinet door 12 is arranged at the slot position of the receiving slot 111. The cabinet door 12 is arranged at the slot position of the receiving slot 111 of the cabinet device 01, and can thus cover the slot to protect the components (such as Figure 1 The battery pack 02 shown or Figure 2 The communication device 07) shown is protected.

[0044] Continue as Figure 3 As shown, the cabinet device 01 may further include a liquid cooling module 13. The liquid cooling module 13 is disposed in the receiving tank 111, and the liquid cooling module 13 may be connected to the battery pack 02 (such as Figure 1 as shown) or communication device 07 (as shown Figure 2 The liquid cooling module 13 is used to dissipate heat for the battery pack 02 or the communication device 07.

[0045] On this basis, the cabinet equipment 01 may also include a liquid cooling unit 14 and a pipe structure 15. The pipe structure 15 is connected to the cabinet door 12. Exemplarily, the pipe structure 15 may be directly connected to the cabinet door 12. Alternatively, the pipe structure 15 and the cabinet door 12 may be respectively connected to the liquid cooling unit 14, and the pipe structure 15 is connected to the cabinet door 12 through the liquid cooling unit 14. In addition, the liquid cooling unit 14 is connected to the liquid cooling module 13 through the pipe structure 15. Through the pipe structure 15, the coolant can flow between the liquid cooling unit 14 and the liquid cooling module 13 to ensure that the coolant can flow to the liquid cooling module 13, so as to complete the heat dissipation of the cabinet body 11 by the liquid cooling module 13.

[0046] When the cabinet door 12 is closed, the distance between the liquid cooling unit 14 and the side wall of the cabinet body 11 is reduced, and a part of the pipe structure 15 is compressed, making the pipe structure 15 prone to being flattened or bent, thereby hindering the flow of the coolant in the pipe structure 15 and reducing the heat dissipation effect of the liquid cooling module 13. The pipe structure 15 may even be damaged when it is flattened or bent multiple times, reducing the service life of the pipe structure 15.

[0047] To solve the above problem, continue as Figure 3 As shown, for the sake of convenience, the depth direction of the cabinet is taken as the X direction, the width direction of the cabinet is taken as the Y direction, and the height direction of the cabinet is taken as the Z direction. Figure 3 The pipeline structure 15 is slidably connected to the cabinet body 11 (in the direction of the arrow in the figure, i.e., the X-axis direction). When the cabinet door 12 is opened, the cabinet door 12 drives the pipeline structure 15 connected to the cabinet door 12 to slide in a direction away from the bottom 1111 of the receiving groove 111. When the cabinet door 12 is closed, the cabinet door 12 drives the pipeline structure 15 connected to the cabinet door 12 to slide in a direction toward the bottom 1111 of the receiving groove 111. In this way, when the cabinet door 12 is closed, the distance between the end of the pipeline structure 15 away from the cabinet door 12 and the cabinet door 12 is increased, so as to avoid the pipeline structure 15 being severely squeezed and deformed due to too small a distance, and thus being flattened or bent, thereby ensuring the circulation of the coolant in the pipeline structure 15. At the same time, the occurrence of damage to the pipeline structure 15 when it is flattened or bent multiple times is reduced; the occurrence of scratches between the pipeline structure 15 and the cabinet 11 after bending is also reduced, preventing the pipeline structure 15 or the cabinet 11 from being worn due to multiple scratches, thereby increasing the service life of the pipeline structure 15 and the cabinet 11. In summary, the cabinet equipment 01 provided in the present application can improve the circulation of the coolant in the pipeline structure 15. At the same time, the service life of the pipeline structure 15 is increased. In addition, after the pipeline structure 15 slides in the direction toward the bottom 1111 of the receiving groove 111, the resistance to the closing of the cabinet door 12 caused by the deformation and bending of the pipeline structure 15 is reduced, which facilitates the closing of the cabinet door 12.

[0048] Further, continue as Figure 3 As shown, the cabinet device 01 may include at least one sliding mechanism 16, and the sliding mechanism 16 may include a first sliding member 161 and a second sliding member 162. The first sliding member 161 is arranged on the side wall of the receiving groove 111. The side wall is an inner wall intersecting with the bottom 1111 of the receiving groove 111. The second sliding member 162 is arranged on the pipeline structure 15. In the direction toward or away from the bottom 1111 of the receiving groove 111 (along Figure 3 In the direction of the arrow in the receiving groove 111, i.e., the X-axis direction), the first sliding member 161 and the second sliding member 162 are slidably connected. At this time, when the cabinet door 12 is closed, the pipeline structure 15 is subjected to a force in the direction toward the bottom 1111 of the receiving groove 111, thereby driving the second sliding member 162 arranged on the pipeline structure 15 to slide relative to the first sliding member 161 in the direction toward the bottom 1111 of the receiving groove 111. The first sliding member 161 is arranged on the side wall of the receiving groove 111, i.e., the pipeline structure 15 and the second sliding member 162 can slide relative to the side wall of the receiving groove 111 in the direction toward the bottom 1111 of the receiving groove 111, thereby realizing a sliding connection between the pipeline structure 15 and the side wall of the receiving groove 111, i.e., a sliding connection between the pipeline structure 15 and the cabinet body 11. In addition, after the pipeline structure 15 is filled with coolant, the weight of the pipeline structure 15 and the coolant inside is relatively large. Under the action of gravity, the connection between the pipeline structure 15 and the liquid cooling unit 14 may be pulled, causing the connection to be deformed or even disconnected. In the embodiment of the present application, in a direction parallel to the bottom 1111 of the receiving tank, the second sliding member 162 can limit the pipeline structure 15, so that the pipeline structure 15 slides along the second sliding member 162 on the first sliding member 161 arranged on the side wall of the receiving tank 111, that is, moves in a direction toward or away from the bottom 1111 of the receiving tank, thereby preventing the pipeline structure 15 from moving in other directions, preventing the pipeline structure 15 from pulling the connection between the pipeline structure 15 and the liquid cooling unit 14 due to gravity and other effects, and preventing the pipeline structure 15 and the liquid cooling unit 14 from loosening or even detaching at the connection due to pulling.

[0049] Exemplarily, the first sliding member 161 may be a groove formed on the side wall of the receiving groove 111, the extension direction of the groove is toward or away from the bottom 1111 of the receiving groove 111, and the second sliding member 162 may be a protrusion slidably disposed in the groove, and the protrusion is connected to the pipeline structure 15. After the groove is formed on the side wall of the cabinet 11 to form a slide rail as the first sliding member 161 and the protrusion is disposed in the groove, the distance between the pipeline structure 15 and the side wall can be reduced, thereby facilitating the arrangement of other devices on the side of the pipeline structure 15 away from the side wall, so as to improve the space utilization rate in the cabinet 11.

[0050] Alternatively, and again illustratively, the first sliding member 161 may be a convex strip fixedly disposed on the side wall of the accommodating groove 111 (not shown in the figure), and the second sliding member 162 may be a convex block having a groove or a through hole, wherein the groove or the through hole is used to accommodate the convex strip so that the convex block slides along the convex strip.

[0051] In some embodiments of the present application, Figure 4 As shown, the receiving tank 111 has a first side wall 1112, and the first side wall 1112 intersects with the bottom 1111 of the receiving tank 111. The cabinet door 12 is hinged to the first side wall 1112 of the receiving tank 111, the liquid cooling unit 14 is arranged on the side of the cabinet door 12 facing the receiving tank 111, and the first sliding member 161 is arranged on the first side wall 1112. At this time, after the cabinet door 12 is hinged to the first side wall 1112 of the receiving tank 111, when the cabinet door 12 rotates relative to the first side wall 1112, the first sliding member 161 is arranged on the first side wall 1112, and the hinge position of the first sliding member 161, the cabinet door 12 and the first side wall 1112 are closer than the other side walls arranged on the receiving tank 111. In the process of closing or opening the cabinet door 12, the required distance to drive the pipeline structure 15 to move is smaller, that is, the required bending degree of the pipeline structure 15 is smaller, which is convenient for the circulation of the cooling liquid in the pipeline structure 15.

[0052] Further, continue as Figure 4 As shown, the pipeline structure 15 is connected to the side of the liquid cooling unit 14 facing the first side wall 1112. After the cabinet door 12 is hinged to the first side wall 1112 of the receiving groove 111, when the cabinet door 12 rotates relative to the first side wall 1112, the closer the position of the liquid cooling unit 14 disposed on the cabinet door 12 is to the hinge between the cabinet door 12 and the first side wall 1112, the smaller the displacement distance, that is, the displacement distance of the liquid cooling unit 14 toward the side of the first side wall 1112 is the smallest. After the pipeline structure 15 is connected to the side of the liquid cooling unit 14 facing the first side wall 1112, during the process of opening or closing the cabinet door 12, the displacement distance of the end of the pipeline structure 15 toward the liquid cooling unit 14 is smaller. Furthermore, the distance between the side of the liquid cooling unit 14 facing the first side wall 1112 and the first sliding member 161 disposed on the first side wall 1112 is small, so that after the pipeline structure 15 is slidably connected to the first sliding member 161 through the second sliding member 162, the length of the pipeline structure 15 is short. This makes the total length of the pipeline structure 15 short, and the pipeline structure 15 is not easy to bend when the cabinet door 12 is closed.

[0053] Further, continue as Figure 4As shown, the cabinet equipment 01 may include N liquid cooling modules 13 and N sliding mechanisms 16. The vertical projection of a first sliding member 161 on the first side wall 1112 is located within the vertical projection of a liquid cooling module on the first side wall 1112. Alternatively, along the stacking direction of the liquid cooling module 13, the vertical projection of the first sliding member 161 on the first side wall 1112 and the vertical projection of the liquid cooling module 13 on the first side wall 1112 are distributed at intervals. Wherein, N≥1, N is an integer. Exemplarily, N is 1, 2, 3, 4, 5, 6, etc. At this time, the first sliding member 161 and the vertical projection of the liquid cooling module 13 on the first side wall 1112 correspond one-to-one, ensuring that the part of the pipeline structure 15 close to the liquid cooling module 13 can be slidably connected to the first side wall 1112 through the sliding mechanism 16, thereby improving the stability of the sliding connection between the pipeline structure 15 and the first side wall 1112.

[0054] The above embodiment Figure 4 As shown, a cabinet device 01 is taken as an example, which includes four liquid cooling modules 13 and four sliding mechanisms 16. In other embodiments of the present application, the number of liquid cooling modules 13 and sliding mechanisms 16 may also be other numbers.

[0055] Continue as Figure 4As shown, the pipeline structure 15 may include a first pipeline 151 and a second pipeline 152 which are connected and communicated in sequence. The first pipeline 151 is connected to the cabinet door 12, and one end of the first pipeline 151 away from the second pipeline 152 is communicated with the liquid cooling unit 14. One end of the second pipeline 152 away from the first pipeline 151 is communicated with the liquid cooling module 13. The second pipeline 152 is connected to the second sliding member 162. When the cabinet door 12 is opened, the cabinet door 12 drives the liquid cooling unit 14 and the first pipeline 151 connected to the liquid cooling unit 14 to move in a direction away from the bottom 1111 of the receiving tank 111, thereby driving the second pipeline 152 connected to the first pipeline 151 to move in a direction toward the cabinet door 12. At this time, the second sliding member 162 connected to the second pipeline 152 will slide on the first sliding member 161 in a direction toward the cabinet door 12. When the cabinet door 12 is closed, the cabinet door 12 drives the liquid cooling unit 14 and the first pipeline 151 connected to the liquid cooling unit 14 to move in the direction toward the bottom 1111 of the receiving tank 111, and then drives the second pipeline 152 connected to the first pipeline 151 to move in the direction away from the cabinet door 12. At this time, the second sliding member 162 connected to the second pipeline 152 will slide on the first sliding member 161 in the direction away from the cabinet door 12. In this way, when the cabinet door 12 is opened, the first pipeline 151 and the second pipeline 152 both move in the direction toward the cabinet door 12, that is, toward the liquid cooling unit 14, to ensure that the first pipeline 151 can be connected to the liquid cooling unit 14. When the cabinet door 12 is closed, the first pipeline 151 and the second pipeline 152 both move away from the cabinet door 12, that is, away from the liquid cooling unit 14, so that the distance between the end of the first pipeline 151 away from the liquid cooling unit 14 and the liquid cooling unit 14 increases, thereby preventing the first pipeline 151 from being severely squeezed and deformed due to too small a distance, and thus being flattened or bent, thereby ensuring the circulation of the coolant in the first pipeline 151. At the same time, the first pipeline 151 is prevented from being damaged due to multiple bends, thereby increasing the service life of the first pipeline 151.

[0056] In addition, if Figure 4As shown, the first pipeline 151 may include a first liquid inlet pipeline 151A and a first liquid return pipeline 151B both connected to the liquid cooling unit 14, and the second pipeline 152 may include a second liquid inlet pipeline 152A and a second liquid return pipeline 152B both connected to the liquid cooling module 13, and the second liquid inlet pipeline 152A and the second liquid return pipeline 152B are both connected to the second sliding member 162. The first liquid inlet pipeline 151A is connected to the second liquid inlet pipeline 152A, and the first liquid return pipeline 151B is connected to the second liquid return pipeline 152B. At this time, the liquid cooling unit 14 is connected to the first liquid inlet pipeline 151A, the first liquid inlet pipeline 151A is connected to the second liquid inlet pipeline 152A, the second liquid inlet pipeline 152A is connected to the liquid cooling module 13, the liquid cooling module 13 is connected to the second liquid return pipeline 152B, the second liquid return pipeline 152B is connected to the first liquid return pipeline 151B, and the first liquid return pipeline 151B is connected to the liquid cooling unit 14. The coolant can form a cold flow loop among the liquid cooling unit 14, the first liquid inlet pipeline 151A, the second liquid inlet pipeline 152A, the liquid cooling module 13, the second liquid return pipeline 152B, and the first liquid return pipeline 151B to complete the continuous heat dissipation in the cabinet 11.

[0057] Furthermore, if Figure 4 As shown, the pipeline structure 15 also includes a third pipeline 153. The third pipeline 153 includes a third liquid inlet pipeline 153A and a third liquid return pipeline 153B, both of which are connected to the liquid cooling module 13. The third liquid inlet pipeline 153A is connected to the second liquid inlet pipeline 152A. At this time, the third liquid inlet pipeline 153A is respectively connected to the second liquid inlet pipeline 152A and the liquid cooling module 13, ensuring that the coolant in the second liquid inlet pipeline 152A can enter the liquid cooling module 13. In addition, the third liquid return pipeline 153B is connected to the second liquid return pipeline 152B. At this time, the third liquid return pipeline 153B is respectively connected to the second liquid return pipeline 152B and the liquid cooling module 13, ensuring that the coolant in the liquid cooling module 13 can flow back to the second liquid return pipeline 152B.

[0058] On this basis, if Figure 5 As shown, the pipeline structure 15 may further include a fixing member 154, which is arranged along the circumference of the second pipeline 152 and connected to the second pipeline 152, and the side of the fixing member 154 away from the second pipeline 152 is connected to the second sliding member 162. The second pipeline 152 is connected to the second sliding member 162 through the fixing member 154, which ensures that the second pipeline 152 can slide on the side wall of the accommodating groove 111 with the second sliding member 162, while improving the connection stability between the second pipeline 152 and the second sliding member 162.

[0059] Exemplarily, the fixing member 154 may be a pipe clamp provided along the outer wall of the second pipe 152 .

[0060] After the first pipeline 151 and the second pipeline 152 are connected, when the cabinet door 12 is closed, the distance between the liquid cooling unit 14 and the side wall of the cabinet body 11 is reduced, and after the first pipeline 151 is squeezed and deformed, a large force is applied to the connection between the first pipeline 151 and the second pipeline 152. Under the action of external force, the seal of the connection between the first pipeline 151 and the second pipeline 152 may fail.

[0061] To solve the above problem, continue as Figure 5 As shown, the pipeline structure 15 may further include a first rotating joint 155. The first rotating joint 155 may include a first joint 1551 and a second joint 1552 that are connected to each other. The first joint 1551 is relative to the second joint 1552 along the axis of the second joint 1552 (eg, Figure 5 The first joint 1551 is coaxially arranged with the first pipeline 151, and the first joint 1551 is connected and communicated with the first pipeline 151, and the second joint 1552 is coaxially arranged with the second pipeline 152, and the second joint 1552 is connected and communicated with the second pipeline 152. The first joint 1551 and the second joint 1552 are rotatably connected along the axis of the second joint 1552, so that the first pipeline 151 connected to the first joint 1551 and the second pipeline 152 connected to the second joint 1552 can rotate relative to each other. When the cabinet door 12 is opened or closed, the first pipeline 151 is subjected to force, which drives the first joint 1551 to rotate relative to the second joint 1552 along the axis of the second joint 1552, so as to reduce the deformation degree of the end of the first pipeline 151 close to the second pipeline 152, thereby reducing the force at the connection between the first pipeline 151 and the second pipeline 152, preventing the sealing failure at the connection between the first pipeline 151 and the second pipeline 152 due to pulling by external force, and reducing the risk of sealing failure between the first pipeline 151 and the second pipeline 152.

[0062] It is understandable that a first rotary joint 155 is provided between the first liquid inlet pipeline 151A and the second liquid inlet pipeline 152A. A first rotary joint 155 is also provided between the first liquid return pipeline 151B and the second liquid return pipeline 152B.

[0063] Similarly, after the first pipeline 151 is connected to the liquid cooling unit 14, when the cabinet door 12 is closed, the distance between the liquid cooling unit 14 and the side wall of the cabinet body 11 is reduced, and after the first pipeline 151 is squeezed and deformed, a large force is applied to the connection between the first pipeline 151 and the liquid cooling unit 14. Under the action of external force, the seal of the connection between the first pipeline 151 and the liquid cooling unit 14 may fail.

[0064] To solve the above problem, continue as Figure 5As shown, the pipeline structure 15 may further include a second rotating joint 156, the second rotating joint 156 includes a third joint 1561 and a fourth joint 1562 that are connected to each other, the third joint 1561 is relative to the fourth joint 1562 along the axis of the fourth joint 1562 (as shown in FIG. Figure 5 The third joint 1561 is coaxially arranged with the first pipeline 151, and the third joint 1561 is connected and communicated with the first pipeline 151, and the fourth joint 1562 is connected and communicated with the liquid cooling unit 14. The third joint 1561 and the fourth joint 1562 are rotatably connected along the axis of the fourth joint 1562, so that the first pipeline 151 connected with the third joint 1561 and the liquid cooling unit 14 connected with the fourth joint 1562 can rotate relative to each other. When the cabinet door 12 is opened or closed, the first pipeline 151 is subjected to force, which drives the third joint 1561 to rotate relative to the fourth joint 1562 along the axis of the fourth joint 1562, so as to reduce the deformation degree of the end of the first pipeline 151 close to the liquid cooling unit 14, thereby reducing the force at the connection between the first pipeline 151 and the liquid cooling unit 14, preventing the sealing failure at the connection between the first pipeline 151 and the liquid cooling unit 14 due to pulling by external force, and reducing the risk of sealing failure between the first pipeline 151 and the liquid cooling unit 14.

[0065] It is understandable that a first rotary joint 155 is provided between the first liquid inlet pipeline 151A and the liquid cooling unit 14 . A first rotary joint 155 is also provided between the first liquid return pipeline 151B and the liquid cooling unit 14 .

[0066] The above embodiment Figure 5 As shown, the axis of the second joint 1552 is parallel to the Z-axis direction, and the axis of the fourth joint 1562 is also parallel to the Z-axis direction. In other embodiments of the present application, the axis of the second joint 1552 may intersect with the Z-axis direction, and the axis of the fourth joint 1562 may also intersect with the Z-axis direction. This application does not make specific limitations.

[0067] Or, in other embodiments of the present application, Figure 6 As shown, the receiving groove 111 may have a second side wall 1113, the cabinet door 12 may be hinged to the first side wall 1112 of the receiving groove 111, and the first sliding member 161 is arranged on the second side wall 1113. The second side wall 1113 intersects with the first side wall 1112. At this time, when the cabinet door 12 is opened or closed, the pipeline structure 15 and the second sliding member 162 are slidably connected relative to the first sliding member 161 arranged on the second side wall 1113, that is, the pipeline structure 15 and the second sliding member 162 can be moved in a direction toward the bottom 1111 of the receiving groove 111 (along the direction of the first sliding member 161). Figure 6The pipeline structure 15 slides relative to the side wall of the accommodating groove 111 in the direction of the arrow, i.e., the X-axis direction, thereby realizing a sliding connection between the pipeline structure 15 and the cabinet equipment 01.

[0068] Alternatively, in some further embodiments of the present application, Figure 7 As shown, along the direction toward or away from the bottom 1111 of the receiving groove 111 (along Figure 7 The cabinet door 12 can be slidably connected to the cabinet body 11 in the direction of the arrow in the drawing, i.e., the X-axis direction). The pipeline structure 15 is also slidably connected to the cabinet body 11. When the cabinet door 12 slides relative to the receiving groove 111, the cabinet door 12 is opened or closed. The cabinet door 12 and the pipeline structure 15 both slide relative to the cabinet body 11 in a direction toward or away from the bottom 1111 of the receiving groove 111, i.e., when the cabinet door 12 is closed, when the cabinet door 12 slides toward the bottom 1111 of the receiving groove 111, the pipeline structure 15 also slides toward the bottom 1111 of the receiving groove 111, thereby reducing the degree of extrusion and deformation of the pipeline structure 15 caused by the closing of the cabinet door 12, and preventing the pipeline structure 15 from being flattened or bent and affecting the circulation of the coolant.

[0069] The above embodiment Figure 3 , Figure 4 , Figure 6 or Figure 7 As shown, the liquid cooling unit 14 is set on the side of the cabinet door 12 facing the cabinet body 11. In other embodiments of the present application, in order to facilitate maintenance of the liquid cooling unit 14, the liquid cooling unit 14 can also be set on the side of the cabinet door 12 away from the cabinet body 11.

[0070] In addition, the above embodiments Figure 3 , Figure 4 , Figure 6 or Figure 7 As shown in the figure, the relative sliding direction of the pipeline structure 15 and the cabinet 11 is perpendicular to the bottom 1111 of the receiving groove 111 (along the Figure 7 In other embodiments of the present application, the sliding direction of the pipeline structure 15 and the cabinet 11 may also be any direction intersecting with the bottom 1111 of the receiving groove 111. This application does not make specific limitations.

[0071] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
