[0033] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0034] like Figures 1 to 4 As shown, this embodiment provides a ring network box 100 with heat dissipation adjustment function, including a base 10, multiple cabinets 20, a cooling component 40, a spacing adjustment component 50, and a drive component 60.

[0035] For ease of reading, this application introduces a first direction X, a second direction Y, and a third direction Z to describe the embodiments of this application. The first direction X, the second direction Y, and the third direction Z can be three non-parallel straight lines in space; further, the first direction X, the second direction Y, and the third direction Z can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction X is described as the X-axis direction of the three-dimensional coordinate system, the second direction Y is the Y-axis direction of the three-dimensional coordinate system, and the third direction Z is the Z-axis direction of the three-dimensional coordinate system.

[0036] Multiple cabinets 20 are arranged sequentially at intervals along a first direction X. Each cabinet 20 is slidably connected to a base 10, and a movable cavity 21 is provided between any two adjacent cabinets 20. Each movable cavity 21 contains a cooling assembly 40 configured to dissipate heat from the two cabinets 20 forming the cavity. Each movable cavity 21 also contains a spacing adjustment assembly 50 configured to adjust the spacing between the two cabinets 20 forming the cavity. A drive assembly 60 is configured to selectively adjust the cooling efficiency of at least one cooling assembly 40 and to selectively provide a driving force to at least one spacing adjustment assembly 50, based on which the spacing adjustment assembly 50 adjusts the spacing between the two cabinets 20.

[0037] Therefore, the ring network box 100 with the heat dissipation adjustment function has the following advantages. The cabinet 20 is arranged in multiple, and the movable cavity 21 is formed between two adjacent cabinets 20, so that the heat accumulation caused by the close arrangement of the cabinets 20 can be avoided, and the working of the electrical equipment in the cabinet 20 is not affected. In addition, each cabinet 20 is connected to the base 10 in a sliding manner, and the distance between the two adjacent cabinets 20 can be adjusted by the driving assembly 60 and the distance adjustment assembly 50, so that the different installation spaces can be adapted. In addition, the cooling assembly 40 is arranged in the movable cavity 21, and the cooling assembly 40 can dissipate heat from the two cabinets 20, thereby further improving the heat dissipation efficiency of each cabinet 20. The cooling efficiency of the cooling assembly 40 and the distance adjustment assembly 50 are driven by the driving assembly 60, so that the cooling efficiency of the cooling assembly 40 and the distance adjustment assembly 50 can be adjusted, and the cost of the ring network box is reduced while the function diversity of the ring network box is improved.

[0038] Please combine Figures 1 to 4 In an embodiment, the cabinet 20 is generally square in structure, and a cavity is arranged in the cabinet 20 to install electrical equipment. When the electrical equipment works, heat is accumulated in the cabinet 20, which causes the temperature to rise, and the electrical equipment works in a high-temperature environment, which affects the normal work of the electrical equipment.

[0039] The base 10 is formed by splicing multiple segments, so that the length of the base 10 in the first direction X can be adjusted according to the total length of the multiple cabinets 20 after the distance adjustment, and then the multiple cabinets 20 after the adjustment operation can be adapted. The base 10 can be provided with a sliding rail to guide the cabinet 20 to slide along the first direction X.

[0040] The ring network box 100 with the heat dissipation adjustment function further comprises multiple folding plates 30. The folding plate 30 can be folded along the first direction X to adjust the length of the entire folding plate 30 in the first direction X. For example, the folding plate 30 can adopt a wave-shaped structure formed by connecting multiple plate members that can be relatively deflected from each other. The number of folding plates 30 is three times the number of movable cavities 21, and each movable cavity 21 corresponds to three folding plates 30. Along the second direction Y, one folding plate 30 is arranged at each end of the movable cavity 21, and along the third direction Z, one folding plate 30 is arranged at the end of the movable cavity 21 away from the ground. Along the first direction X, the two ends of the folding plate 30 are connected to the two adjacent cabinets 20, respectively, so that when the distance between the two adjacent cabinets 20 is adjusted, the folding plate 30 can be folded or stretched to adapt to different distances.

[0041] Therefore, the movable cavity 21 is closed on both sides in the second direction Y and at the end away from the base 10 by the three folding plates 30, which improves the appearance of the entire ring network box and avoids the problem of dust falling on the structure in the movable cavity 21.

[0042] Please combine Figures 1 to 4In an embodiment, the number of cooling assemblies 40 is the same as the number of active cavities 21, i.e. one cooling assembly 40 is arranged in each active cavity 21. The cooling assembly 40 comprises two cooling modules, which are arranged on the same side of the two cabinet bodies 20 respectively, so as to cool the two cabinet bodies 20 respectively by the two cooling modules. In addition, the two cooling modules are spaced apart along the first direction X. The cooling module comprises a cold plate 41 and a moving plate 42, which is slidably connected to the cold plate 41 along the first direction X, for adjusting the volume of the cold groove 411. The driving assembly 60 is configured to drive the moving plate 42 to move relative to the cold plate 41.

[0043] Along the first direction X, one side of the cold plate 41 is connected to the cabinet body 20, and the other side of the cold plate 41 is provided with a cold groove 411 for accommodating the cooling liquid. The cold plate 41 is detachably connected to the cabinet body 20, for example, by fasteners such as bolts, so as to facilitate replacement of different sizes of cabinet bodies 20, and the cold plate 41 can be detached for subsequent installation of the cabinet body 20. The cold plate 41 is made of a material with heat conduction capacity, such as metal, and the cabinet body 20 is also made of metal. When the cold plate 41 is connected to the cabinet body 20, the cold plate 41 is surface-bonded and thermally coupled to the cabinet body 20. When the cooling liquid flows in the cold groove 411, the cooling liquid exchanges heat with the cabinet body 20 through the cold plate 41, thereby removing heat from the cabinet body 20.

[0044] Along the first direction X, the cold groove 411 extends inward from the side of the cold plate 41 away from the cabinet body 20 to which it is connected. A plurality of cold grooves 411 are provided on the cold plate 41, which are sequentially and spaced apart along the second direction Y, and the cold groove 411 has a relatively large extension length along the third direction Z, so that the plurality of cold grooves 411 can cover more areas of the cabinet body 20, thereby improving the heat dissipation efficiency of the cabinet body 20.

[0045] Along the first direction X, the side of the moving plate 42 close to the cold plate 41 is provided with a plurality of moving protrusions 421, which are correspondingly arranged with the plurality of cold grooves 411. Along the first direction X, the moving protrusions 421 are partially and slidably arranged in the cold grooves 411, and a sliding sealing structure can be provided between the moving protrusions 421 and the cold grooves 411 to improve the sealing between the surface of the moving protrusions 421 and the groove wall of the cold grooves 411.

[0046] The ring network cabinet 100 with heat dissipation adjustment function also comprises a cooling liquid circulating device (not shown in the figure). The cooling liquid circulating device is used to transport cooling liquid to the cold groove 411 of each cold plate 41 by using equipment such as a circulating pump. After the cooling liquid completes heat exchange with the cabinet body 20, it flows back to the circulating pump, is cooled by a cooling device, and is then transported to the cold groove 411 by the circulating pump. Temperature detection elements, such as temperature sensors, can be arranged at each cabinet body 20 to detect the current temperature of each cabinet body 20.

[0047] Thus, when the temperature detection member detects that the temperature of the cabinet 20 where it is located is high, the driving assembly 60 can drive the corresponding moving plate 42 of the cabinet 20 to move towards the side of the corresponding cold plate 41, so as to reduce the width of the cold groove 411 in the first direction X by moving the protruding part 421 in the cold groove 411, thereby reducing the cross-sectional area of the cold groove 411, and under the condition that the flow of the cooling liquid delivered by the cooling liquid circulating device to each cold groove 411 remains unchanged, the flow rate of the cooling liquid in the cold groove 411 can be increased, thereby improving the cooling effect of the cooling module on the cabinet 20 where it is located.

[0048] In the embodiment, along the first direction X, the side of the moving plate 42 close to the cold plate 41 is provided with a plug-in part 422, and the side of the cold plate 41 close to the moving plate 42 is provided with a plug-in groove 412. The outer periphery of the plug-in part 422 is provided with a limiting protrusion 4220, and the number of limiting protrusions 4220 is one or more. When the number of limiting protrusions 4220 is more, along the first direction X, the plurality of limiting protrusions 4220 are sequentially and spaced apart. The groove wall of the plug-in groove 412 is provided with a plurality of limiting grooves 413, the limiting grooves 413 are communicated with the plug-in groove 412, and along the first direction X, the plurality of plug-in grooves 412 are sequentially and spaced apart. The limiting protrusion 4220 is of elastic material, so as to be elastically deformed, and the limiting groove 413 is used to accommodate the limiting protrusion 4220, so as to realize the relative fixation between the moving plate 42 and the cold plate 41 after the moving plate 42 moves a certain distance relative to the cold plate 41. Subsequently, the moving plate 42 can continue to move relative to the cold plate 41 by overcoming the resisting action of the groove wall of the limiting groove 413 on the limiting protrusion 4220 through the driving assembly 60, thereby realizing the step-by-step adjustment of the cooling efficiency.

[0049] Please combine Figures 2 to 5 In an embodiment, the number of distance adjustment assemblies 50 is the same as the number of movable cavities 21, that is, one distance adjustment assembly 50 is arranged in each movable cavity 21. The distance adjustment assembly 50 comprises two connecting plates 51, and the two connecting plates 51 are connected to the proximal sides of the two cabinets 20 respectively. The driving assembly 60 is configured to selectively drive connect the two connecting plates 51.

[0050] The connecting plate 51 is arranged along the first direction X, and the two connecting plates 51 in the same movable cavity 21 are spaced apart along the first direction X. One end of the connecting plate 51 is connected to the cabinet 20, and the connecting plate 51 can be detachably connected to the cabinet 20 through bolts or other fasteners, so as to be detached from the new cabinet 20 after the cabinet 20 is replaced.

[0051] In the embodiment, the driving assembly 60 comprises a connecting module 62, a selecting module 63, a distance adjusting module 64, and a first driving member 61. The number of the connecting module 62 is the same as that of the interval adjusting assembly 50, and the connecting module 62 comprises two connecting members 621 for connecting with the connecting plate 51 and / or the moving plate 42. The number of the selecting module 63 is the same as that of the connecting module 62, and the selecting module 63 is in transmission connection with the two connecting members 621 of the corresponding connecting module 62 for driving the two connecting members 621 to move along the second direction Y, and based on the movement of the connecting members 621 along the second direction Y, the connecting members 621 are selectively connected with at least one of the connecting plate 51 and the moving plate 42. The number of the distance adjusting module 64 is the same as that of the connecting module 62, and the distance adjusting module 64 is configured to adjust the interval of the two connecting members 621 of the corresponding connecting module 62 along the first direction X. The first driving member 61 is in transmission connection with the plurality of distance adjusting modules 64 for providing driving force to the plurality of distance adjusting modules 64.

[0052] The distance adjusting module 64 comprises a double-threaded screw rod 641 and two screw rod sliders 642. The first driving member 61 is in transmission connection with the double-threaded screw rod 641 for driving the double-threaded screw rod 641 to rotate. The double-threaded screw rod 641 is in transmission connection with the two screw rod sliders 642 for driving the two screw rod sliders 642 to move close to or far away from each other along the first direction X.

[0053] The double-threaded screw rod 641 is provided with two threads with opposite rotation directions. The two screw rod sliders 642 are respectively arranged in cooperation with the two threads, so as to drive the two screw rod sliders 642 to slide synchronously through the rotation of the double-threaded screw rod 641, and then drive the two connecting members 621 to move close to or far away from each other along the first direction X through the two screw rod sliders 642, so as to drive the two connecting plates 51 or the two moving plates 42 to move along the first direction X.

[0054] The driving assembly 60 further comprises a plurality of connecting shafts 65. The double-threaded screw rods 641 of any adjacent two distance adjusting modules 64 are in transmission connection through the connecting shafts 65. The first driving member 61 is in transmission connection with one double-threaded screw rod 641 or one connecting shaft 65. The plurality of connecting shafts 65 are coaxially arranged with the plurality of double-threaded screw rods 641, so as to form an integral shaft structure together with the plurality of double-threaded screw rods 641. The first driving member 61 is a motor, and is coaxially connected to one end of the shaft structure, so as to drive the plurality of double-threaded screw rods 641 to rotate synchronously through the first driving member 61, which can realize single motor driving a plurality of structures, thereby reducing the cost of the equipment.

[0055] It is worth noting that the shaft-like structure and the first driving member 61 can be installed in the base 10, and the shaft-like structure can be rotatably connected with the base 10, and the screw block 642 can extend into the movable cavity 21 through the base 10, so as to be installed with the connecting member 621 in the movable cavity 21.

[0056] In the embodiment, the screw block 642 is provided with a sliding groove 6421 extending along the second direction Y, and the sliding groove 6421 is located in the region of the screw block 642 extending into the movable cavity 21. Along the second direction Y, the screw block 642 is arranged at intervals on the side of the connecting plate 51 away from the moving plate 42, and the sliding groove 6421 is arranged on the side of the screw block 642 close to the connecting plate 51. One end of the connecting member 621 is slidably arranged in the sliding groove 6421, and the other end of the connecting member 621 is used to cooperate with the connecting plate 51 and the moving plate 42, and the end of the connecting member 621 in the sliding groove 6421 can be moved away from the sliding groove 6421, so as to release the connection relationship between the connecting member 621 and the screw block 642, so as to facilitate the movement of a single connecting plate 51 or moving plate 42.

[0057] It can be understood that in the present application, the connecting member 621 can also be moved along the second direction Y, so that the connecting member 621 can be connected with only one of the connecting plate 51 and the moving plate 42 at the same time, so as to realize the movement of a single connecting plate 51 or moving plate 42, and for part of the two adjacent cabinet bodies 20, only the movement of a single cabinet body 20 relative to the other cabinet body 20 is driven to adjust the distance between the two cabinet bodies 20, and the adjustment of the cooling efficiency of any one cabinet body 20 can also be realized by driving the movement of any one moving plate 42 between the two cabinet bodies 20.

[0058] In the embodiment, the selection module 63 includes two second driving members 631, and the two second driving members 631 are respectively drivingly connected with the two connecting members 621 of the same connecting module 62, and are used to drive the two connecting members 621 to slide along the second direction Y relative to the screw block 642.

[0059] The second driving member 631 can adopt an electromagnetic spring, and a driving end of the electromagnetic spring is connected to the connecting member 621 through a connecting rod 632. The electromagnetic spring can provide a driving force along the second direction Y to the connecting member 621 after being energized, thereby driving the connecting member 621 to slide back and forth along the second direction Y. The second driving member 631 can be installed in the base 10, and the connecting rod 632 is provided in a substantially "L" shape. A through groove 6422 is formed on one side of the second driving member 631 close to the connecting member 621, and the through groove 6422 extends along the second direction Y and communicates with the sliding groove 6421. Along the second direction Y, the through groove 6422 extends to the opening of the sliding groove 6421 away from one end of the double-threaded screw rod 641, and the connecting rod 632 is partially and slidably arranged in the through groove 6422, so that one end of the connecting rod 632 can extend into the sliding groove 6421 through the through groove 6422 to be connected to the connecting member 621, and the arrangement of the through groove 6422 also allows the part of the connecting rod 632 in the through groove 6422 to move away from the sliding groove 6421 together with the connecting member 621.

[0060] In this way, the two connecting members 621 are controlled by the two second driving members 631 respectively, so that the two connecting members 621 of the same connecting module 62 can selectively receive the driving force along the first direction X provided by the double-threaded screw rod 641 through the screw block 642.

[0061] Please refer to Figures 2 to 5 In an embodiment, along the second direction Y, the moving plate 42 is arranged in a spaced manner with the connecting plate 51, and the connecting plate 51 is located on one side of the moving plate 42 close to the double-threaded screw rod 641. The connecting member 621 includes a main body part 6210, a first connecting part 6211, and a second connecting part 6212, and the first connecting part 6211 and the second connecting part 6212 are protruded on the outer periphery of the main body part 6210.

[0062] The main body part 6210 is in a substantially cylindrical structure, and along the third direction Z, the heights of the first connecting part 6211 and the second connecting part 6212 are both greater than the outer diameter of the main body part 6210, and the upper and lower ends of the first connecting part 6211 and the second connecting part 6212 both exceed the main body part 6210.

[0063] The connecting plate 51 is provided with a first movable groove 52, and the connecting member 621 is at least partially and slidably arranged in the first movable groove 52, for sliding relative to the connecting plate 51 along the first direction X and the second direction Y.
