Description

Technical Field

[0001] This application relates to the technical field of mechanism design, and particularly relates to a chassis and a cabinet. Background Art

[0002] A cabinet is a special cabinet for artificial intelligence computing, which is usually configured with multiple high-performance central processing units or graphics processing units to support the development and training of large-scale deep learning models. In order to improve the computing power density, it is required that more nodes can be concentrated in the same cabinet to achieve efficient utilization of resources.

[0003] However, in the related art, the coolant between server nodes is connected, and the power supply of server nodes and the signal interconnection between server nodes both need to be connected by pipelines or cables, resulting in a large number of pipelines and cables that need to be connected between the cabinet and server nodes, which not only increases the workload and difficulty of cabinet installation, improves the complexity of cabinet operation and maintenance, but also prolongs the delivery time of the cabinet. Summary of the Invention

[0004] This application provides a chassis and a cabinet to at least solve the problems in the related art that there are a large number of pipelines and cables that need to be connected between the cabinet and server nodes, increasing the workload and difficulty of cabinet installation, improving the complexity of cabinet operation and maintenance, and prolonging the delivery time of the cabinet.

[0005] This application provides a chassis, including a box body, a liquid cooling blind plug connector, a power supply blind plug connector, and a signal blind plug connector.

[0006] Among them, the box body has a rear window. The power supply blind plug connector is arranged in the middle of the rear window of the box body. The signal blind plug connector includes two groups of signal connectors, and the two groups of signal connectors are respectively arranged on both sides of the power supply blind plug connector. The liquid cooling blind plug connector includes a liquid inlet connector and a liquid outlet connector, and the liquid inlet connector and the liquid outlet connector are respectively arranged on both sides of the signal blind plug connector.

[0007] This application also provides a cabinet, including:

[0008] A cabinet body, in which a liquid supply and return manifold, a cable tray, and a power supply bus assembly are provided;

[0009] The chassis as provided in the first aspect of the present invention, the liquid cooling blind plug connector of the chassis can be plugged into the fluid connector of the liquid supply and return manifold, the power supply blind plug connector of the chassis can be plugged into the power supply connector of the power supply bus assembly, and the signal blind plug connector of the chassis can be plugged into the signal connector of the cable tray.

[0010] Through the present application, since the rear window of the chassis implemented by the present invention is provided with a liquid cooling blind plug connector, a power supply blind plug connector and a signal blind plug connector, the connections between the chassis and the cabinet of the embodiment of the present invention, namely, the three parts of liquid, electricity and signal, can all be connected by blind plug connections, thereby getting rid of the numerous pipes and cables between the traditional cabinets and chassis, so that the server nodes can be easily deployed inside the cabinet, and can solve the defects of the related technology that there are many pipes and cables between the chassis and cabinets, the high installation workload and difficulty of the equipment, and can achieve integrated delivery.

[0011] On this basis, the power supply blind plug connector is located in the middle of the rear window of the chassis, and the force generated during the plugging and unplugging process can be more evenly distributed on the structure of the chassis. This is because the middle of the chassis is relatively stable, and when subjected to force, it can better transfer the force to the entire chassis frame, avoiding local deformation or damage caused by uneven force. The signal connectors are symmetrically distributed on both sides of the chassis, which not only makes the force at the rear window of the chassis more uniform during the plugging process, reducing the risk of deformation of the rear window of the chassis, but also improves the smoothness of the signal routing in the signal connector mounting plate. The liquid inlet connector and the liquid outlet connector are respectively located at both ends of the rear window, which can not only ensure that the two ends of the chassis are subjected to uniform force during the blind plugging process, but also avoid the liquid cooling blind plug connector being concentrated on one side, resulting in the chassis being subjected to sideways force during the insertion of the cabinet, causing damage to the connector. It can also leave enough space for the bending and fixing structure of the cold pipe, allowing the diameter of the cold pipe to be set thicker to improve the liquid cooling effect.

[0012] Therefore, the chassis of the embodiment of the present invention can not only realize the blind plug connection of the three parts of liquid, electricity and signal between the chassis and the cabinet, reduce the installation workload and difficulty of the cabinet, and realize integrated delivery, but also avoid local deformation or damage of the chassis due to uneven force, and help to improve the smoothness of the signal routing in the mounting plate of the signal connector, and leave enough space for the bending and fixing structure of the cold pipe.

[0013] The cabinet of the second aspect of the present invention includes or uses the chassis of the first aspect of the present invention, and thus has its beneficial effects, namely, the connections between the chassis of the embodiment of the present invention and the cabinet, namely, the three parts of liquid, electricity and signal, can all be connected by blind plug connection, thereby getting rid of the numerous pipes and cables between the traditional cabinets and the chassis, so that the server nodes can be easily deployed inside the cabinet, and can solve the defects of the related technology that there are many pipes and cables between the chassis and the cabinet, the high installation workload and work difficulty of the equipment, and can achieve integrated delivery.

[0064] If the background art part does not describe the defects of the related technology in detail, the defects of the related technology will be analyzed in detail here to introduce this solution.

[0065] The following describes the embodiments of the present invention in combination with the attached Figures 1 to 21 drawings.

[0066] An embodiment of the present application provides a chassis 100, as Figure 1As shown, the chassis 100 of the embodiment of the present invention includes a chassis body 1, a liquid cooling blind-plug connector 2, a power supply blind-plug connector 3 and a signal blind-plug connector 104.

[0067] The box body 1 has a rear window 103. The power supply blind plug connector 3 is arranged in the middle of the rear window 103 of the box body 1. The signal blind plug connector 104 includes two groups of signal connectors 1042, and the two groups of signal connectors 1042 are respectively arranged on both sides of the power supply blind plug connector 3. The liquid cooling blind plug connector 2 includes a liquid inlet connector 2a and a liquid outlet connector 2b, and the liquid inlet connector 2a and the liquid outlet connector 2b are respectively arranged on both sides of the signal blind plug connector 104.

[0068] Through the present application, since the rear window 103 of the chassis 100 implemented by the present invention is provided with a liquid cooling blind plug connector 2, a power supply blind plug connector 3 and a signal blind plug connector 104, the connections of the three parts of liquid, electricity and signal between the chassis 100 of the embodiment of the present invention and the cabinet can all be connected by blind plug connection, thereby getting rid of the numerous pipes and cables between the traditional cabinet and the chassis 100, so that the server nodes can be easily deployed inside the cabinet, which can solve the defects of the related technology that there are many pipes and cables between the chassis 100 and the cabinet, the high installation workload and difficulty of the equipment, and can achieve integrated delivery.

[0069] On this basis, the power supply blind plug connector 3 is arranged in the middle of the rear window 103 of the box body 1, and the force generated during the plugging and unplugging process can be more evenly distributed on the structure of the chassis 100. This is because the middle part of the chassis 100 is relatively stable, and when subjected to force, it can better transfer the force to the entire chassis 100 frame, avoiding local deformation or damage caused by uneven force. The signal connector 1042 is symmetrically distributed on both sides of the chassis 100, which can not only make the force at the rear window 103 of the chassis 100 more uniform during the plugging process, reduce the risk of deformation of the rear window 103 of the chassis 100, but also improve the smoothness of the signal routing in the connector mounting plate 1041. The liquid inlet connector 2a and the liquid outlet connector 2b are respectively arranged at the two ends of the rear window 103, which can not only ensure that the two ends of the chassis 100 are subjected to uniform force during the blind plugging process, but also avoid the liquid cooling blind plug connector 2 being concentrated on one side, resulting in the chassis 100 being subjected to force sideways during the insertion of the cabinet, causing damage to the connector. It can also leave enough space for the bending and fixing structure of the cooling pipe, allowing the diameter of the cooling pipe to be set thicker to improve the liquid cooling effect.

[0070] Therefore, the chassis 100 of the embodiment of the present invention can not only realize the blind plug connection of the three parts of liquid, electricity and signal between the chassis 100 and the cabinet, reduce the installation workload and difficulty of the cabinet, and realize integrated delivery, but also avoid local deformation or damage of the chassis 100 due to uneven force, and help to improve the smoothness of the signal routing in the installation plate of the signal connector 1042, and leave enough space for the bending and fixing structure of the cold pipe.

[0071] In one embodiment, as Figure 20 shown, the minimum distance between the liquid inlet joint 2a and / or the liquid outlet joint 2b and the signal connector 1042 in the cabinet width direction is d1, and the dimension of the chassis 100 in the cabinet width direction is d2; 0.044 ≤ d1 / d2 ≤ 0.057.

[0072] In one embodiment, when the ratio of d1 / d2 is within the above range, it can be ensured that there is no need to set a large avoidance notch 10411 on the connector mounting plate 1041.

[0073] As Figure 21 shown, since the avoidance notch 10411 is provided at the position corresponding to the liquid inlet joint 2a and the liquid outlet joint 2b on the connector mounting plate 1041, the liquid inlet joint 2a and the liquid outlet joint 2b are arranged in the avoidance notch 10411. When the minimum distance between the liquid inlet joint 2a and / or the liquid outlet joint 2b and the signal connector 1042 in the cabinet width direction is less than the above range, it will cause a need to open a large avoidance notch on the connector mounting plate 1041, resulting in a reduction in the volume of the connector mounting plate 1041.

[0074] In a preferred embodiment, d1 = 27.4 mm, d2 = 536 mm, d1 / d2 ≈ 0.511.

[0075] The minimum distance between the signal connector 1042 and the power supply blind mating connector 3 in the cabinet width direction is d3, and the dimension of the chassis 100 in the cabinet width direction is d2; 0.038 ≤ d3 / d2 ≤ 0.051.

[0076] When the ratio of d3 / d2 is within the above range, it can be ensured that the signal connector 1042 and the power supply blind mating connector 3 will not collide during the floating process.

[0077] In a preferred embodiment, d3 = 24.35, d3 / d2 ≈ 0.045.

[0078] The distance between the liquid cooling blind mating connector 2 and one side wall of the chassis 100 in the cabinet width direction is d4, and the dimension of the chassis 100 in the cabinet width direction is d2; 0.017 ≤ d4 / d2 ≤ 0.029.

[0079] Since the power cord needs to pass through the gap between the supply and return liquid manifold 5 and the cabinet to connect the power supply module of the chassis 100, and the installation position of the supply and return liquid manifold 5 needs to correspond to the liquid inlet joint 2a and the liquid outlet joint 2b, when the minimum distance between the liquid inlet joint 2a and / or the liquid outlet joint 2b and the signal connector 1042 in the cabinet width direction exceeds the above range, it is easy to cause difficulties in connecting the power cord to the power supply module of the chassis 100.

[0080] On this basis, ventilation holes 106 can be provided on the rear window 103 between the signal connector 1042 and the power supply blind plug connector 3, and also on the rear window 103 between the signal connector 1042 and the liquid cooling blind plug connector 2. When the gaps between the liquid inlet joint 2a and the signal connector 1042, between the signal connector 1042 and the power supply blind plug connector 3, and between the signal connector 1042 and the liquid outlet joint 2b are within the above ranges, the vents can be evenly distributed on the rear window of the chassis, without increasing the wind resistance inside the chassis, which can help improve the air cooling effect of the chassis 100.

[0081] In a preferred embodiment, the sum of the dimensions of the liquid inlet joint 2a and the liquid outlet joint 2b in the width direction of the chassis 100, the sum of the dimensions of the two groups of signal connectors 1042 in the width direction of the chassis 100, and the dimension ratio of the power supply blind plug connector 3 in the width direction of the chassis 100 are: 22~28:54~63:12~18.

[0082] This ratio can reasonably allocate the internal space of the chassis 100, ensure that the layout of each component in the width direction of the chassis 100 is compact and orderly, avoid space waste or congestion, and improve the space utilization rate of the chassis 100.

[0083] In an embodiment, the signal connector 1042 is a high-density connector, with a dimension of 130.25 mm in the width direction of the chassis 100. The sum of the dimensions of the liquid inlet joint 2a and the liquid outlet joint 2b in the width direction of the chassis 100 is 112 mm, and the dimension of the power supply blind plug connector 3 in the width direction of the chassis 100 is 35 mm. This ratio can reasonably allocate the internal space of the chassis 100 on the basis of the large size occupied by the high-density connector, ensure that the layout of each component in the width direction of the chassis 100 is compact and orderly, avoid space waste or congestion, and improve the space utilization rate of the chassis 100.

[0084] In an embodiment, as Figure 12 shown, the signal blind plug connector 104 includes a connector mounting plate 1041 and a signal connector 1042.

[0085] Among them, the connector mounting plate 1041 is connected to the rear window 103. The signal connector 1042 is arranged on the connector mounting plate 1041, and the signal connector 1042 is a high-density connector.

[0086] In an embodiment, the signal blind plug connector 104 further includes a guide block 1043. The guide block 1043 is arranged on the connector mounting plate 1041, and a guide hole 1044 is formed in the guide block 1043. Along the insertion direction of the signal blind plug connector 104, the guide hole 1044 is set with an enlarged diameter.

[0087] During the plugging process, the guiding block 1043 can cooperate with the second guiding pin 1017 on the cabinet, so that the signal blind plug connector 104 can be accurately plugged into the cabinet signal connector 6034, and damage to the signal blind plug connector 104 or the cabinet signal connector 6034 caused by misplugging can be avoided.

[0088] In one embodiment, an air cooling mechanism is further provided in the chassis 100. A plurality of ventilation holes 106 are provided on the rear window 103 of the box body 1. With such an arrangement, the chassis 100 of the embodiment of the present invention can dissipate heat from the electronic devices in the chassis 100 through the air cooling mechanism and the liquid cooling device at the same time. The air cooling mechanism can drive the airflow to carry the heat on the electronic devices out through the ventilation holes 106, so as to ensure sufficient heat dissipation even when the density of the electronic devices in the chassis 100 is relatively high.

[0089] In one embodiment, the guiding blocks 1043 are arranged in pairs, and at least one guiding block 1043 is provided at each end of each group of signal connectors 1042.

[0090] With such an arrangement, the guiding blocks 1043 can limit the signal connectors 1042 from both sides of the signal connectors 1042, thereby preventing the chassis 100 of the server from tilting during the plugging process.

[0091] In one embodiment, an avoidance groove 1033 is formed at the rear window 103. The liquid cooling blind plug connector 2 is connected to the bottom wall and / or side wall of the box body 1 and passes through the avoidance groove 1033.

[0092] With such an arrangement, it is also possible to avoid deformation of the rear window 103 of the chassis 100 caused by the impact force during the plugging process due to the connection of the liquid cooling blind plug connector 2 to the rear window 103 of the chassis 100, which helps to strengthen the rigidity of the rear window 103 of the chassis 100.

[0093] As a transformable implementation manner, in an embodiment not shown in one of the drawings, the liquid cooling blind plug connector 2 is connected to the rear window 103 of the chassis 100.

[0094] In one embodiment, as Figure 6 and Figure 7 shown, the liquid cooling blind plug connector 2 includes a floating module and a quick-connect joint 204.

[0095] Among them, the floating module is connected to the bottom wall and / or side wall of the box body 1. The quick-connect joint 204 is arranged on the floating module and can float relative to the floating module in the radial and / or axial directions of the quick-connect joint 204.

[0096] By such arrangement, during the process of the chassis 100 being plugged into the cabinet, the liquid-cooled blind-plug connector 2 can float along the axial or radial direction of the liquid-cooled blind-plug connector 2 relative to the floating module, thereby absorbing the manufacturing tolerance of the cabinet end, so that the liquid-cooled blind-plug connector 2 can be accurately docked with the fluid connector 504 on the cabinet, and ensure that the connection between the liquid-cooled blind-plug connector 2 and the fluid connector 504 on the cabinet is reliable and leak-free.

[0097] In one embodiment, Figure 7 As shown, the floating module includes a base 201, an adapter joint 202 and a floating adjustment structure 203. The base 201 is connected to the box body 1, and a joint through hole 2012 and an adjustment hole 2013 are formed on the base 201. The adapter joint 202 includes a connecting portion 2021 and a connecting portion 2022, the connecting portion 2021 passes through the adjustment hole 2013, and the connecting portion 2022 is arranged on the outer periphery of the connecting portion 2021. The floating adjustment structure 203 passes through the adjustment hole 2013 and the connecting portion 2022, and the floating adjustment structure 203 can float relative to the radial direction of the adjustment hole 2013, and the adapter joint 202 can float relative to the box body 1 along the axial direction of the adapter joint 202.

[0098] In one embodiment, Figures 2 to 5 As shown, a cover plate 101 is provided on one side of the box body 1, and the cover plate 101 includes a cover plate body 1011 and a sub-cover body 1013. A notch 1012 is formed on one side of the cover plate body 1011 close to the rear window 103 of the box body 1. The sub-cover body 1013 is detachably arranged at the notch 1012, and the distance between the sub-cover body 1013 and the first wall 102 of the box body 1 is greater than the distance between the cover plate body 1011 and the first wall 102. The first wall 102 is arranged opposite to the cover plate 101. The liquid-cooled blind plug connector 2 is arranged at the rear window 103 of the box body 1, and is located between the sub-cover body 1013 and the first wall 102, and can float along the radial direction and / or axial direction of the liquid-cooled blind plug connector 2.

[0099] Since the distance between the sub-cover body 1013 and the first wall 102 of the box body 1 is greater than the distance between the cover body main body 10131 and the first wall 102, during the floating process of the liquid-cooled blind plug connector 2, the sub-cover body 1013 can reduce the risk of the liquid-cooled blind plug connector 2 colliding with the cover plate 101 of the box body 1, increase the floating range of the liquid-cooled blind plug connector 2, and help ensure that the connection between the liquid-cooled blind plug connector 2 and the fluid connector 504 on the cabinet is more reliable.

[0100] On this basis, since the area of the sub-cover 1013 itself is relatively small, when using the same material and material thickness, the structural strength of the sub-cover 1013 itself can be greater than that of the cover body 1011. The sub-cover 1013 is connected to the box body 1 and the cover body 1011, which helps to increase the structural strength of the rear window 103 of the box body 1 and the cover body 1011.

[0101] Moreover, since the adapter joint 202 itself includes a connecting pipe portion 2021 and a connecting portion 2022, the volume of the adapter joint 202 itself is relatively large. On this basis, the floating adjustment structure 203 is connected to the connecting portion 2022 on the outer periphery of the connecting pipe portion 2021, so that the entire adapter joint 202 floats along the radial direction and / or the axial direction of the connecting joint, which makes the space required for the adapter joint 202 during the floating process relatively large, and it is necessary to reserve space in the box body 1 for the adapter joint 202 to float. The box body 1 of the server in the embodiment of the present invention can reserve more space in the box body 1 through the sub-cover body 1013, increase the floating range of the liquid-cooled blind plug joint 2, and prevent the liquid-cooled blind plug joint 2 from colliding with the box body 1 during the floating process.

[0102] In one embodiment, as Figure 2 shown, the avoidance groove 1033 is provided with an upper opening, and the sub-cover body 1013 includes a cover body main body 10131, a first connecting edge 10132, and a second connecting edge 10134. Among them, the first connecting edge 10132 and the second connecting edge 10134 are connected to the cover body main body 10131. The first connecting edge 10132 is used to abut against the rear window 103 of the box body 1 and is provided with a first connecting portion 10133 capable of connecting to the rear window 103. The second connecting edge 10134 is used to abut against the side wall of the box body 1 and is provided with a second connecting portion 10135 capable of connecting to the side wall of the box body 1.

[0103] In order to ensure good structural strength at the rear window 103 of the box body 1 and prevent the box body 1 from deforming when subjected to external forces, such as improper operations during handling, collision, or installation, which may affect the overall structural integrity of the box body 1. In the related art, the opening for the liquid-cooled blind plug joint 2 to extend out at the rear window 103 of the box body 1 is generally formed in the middle of the rear window 103 and is not connected to the upper end, otherwise there is a risk of affecting the structural strength of the rear window 103 of the box body 1 and causing the rear window 103 to deform easily.

[0104] This makes it such that in the related art, the installation of the liquid-cooled blind plug joint 2 generally involves obliquely inserting the liquid-cooled blind plug joint 2 into the box body 1 from the end of the box body 1. During this process, the liquid-cooled blind plug joint 2 is prone to interfere with the main board at the bottom of the box body 1. Therefore, it is necessary to open a relatively large cut groove on the main board to prevent the liquid-cooled blind plug joint 2 from damaging the main board, which reduces the area of the main board and affects the function expansion of the server.

[0105] The chassis 100 of the server in the embodiment of the present application is provided with an avoidance groove 1033 with an upper opening at the rear window 103, which enables the liquid-cooled blind plug joint 2 to be installed into the box body 1 from top to bottom, avoiding damage to the main board of the server caused by oblique insertion installation, so that it is not necessary to set a relatively large cut groove on the main board, which helps to increase the area of the main board.

[0106] Based on this, in the embodiments of the present application, as Figure 4 and Figure 5 shown, the cover plate main body 1011 is arranged to include a first connecting edge 10132 and a second connecting edge 10134, and the first connecting edge 10132 and the second connecting edge 10134 can be respectively connected to the rear window 103 of the box body 1 and the side wall of the box body 1. After the sub-cover body 1013 is connected to the box body 1, the first connecting edge 10132 can jointly form a closed through hole with the avoidance groove 1033 with an upper opening, and the second connecting edge 10134 can be connected to the side wall of the box body 1, so that the impact received at the rear window 103 can be transmitted to the side wall of the box body 1, thereby enhancing the structural strength at the rear window 103.

[0107] Therefore, the box body 1 of the server in this embodiment can allow the liquid cooling blind plug connector 2 to be installed into the box body 1 from top to bottom, so as to avoid damage to the main board of the server caused by oblique plug installation, so that there is no need to set a large cut groove on the main board, which helps to increase the area of the main board and does not affect the structural strength at the rear window 103 of the box body 1.

[0108] In one embodiment, the sub-cover body 1013 is provided with one of a guiding convex portion 10136 and a base guiding hole 20111, and a third connecting hole 10137.

[0109] The liquid cooling blind plug connector 2 is provided with the other of the guiding convex portion 10136 and the base guiding hole 20111, and a fourth connecting hole 20112; the guiding convex portion 10136 can be limited in the base guiding hole 20111 and align the third connecting hole 10137 with the fourth connecting hole 20112.

[0110] By setting like this, when installing the chassis 100 of the server of the present application, the operator can first install the liquid cooling blind plug connector 2 on the box body 1, and then align the guiding convex portion 10136 on the sub-cover body 1013 with the base guiding hole 20111 on the liquid cooling blind plug connector 2, so that the third connecting hole 10137 and the fourth connecting hole 20112 are aligned, thereby connecting the sub-cover body 1013 to the fluid connector 504, and connecting the first connecting edge 10132 and the second connecting edge 10134 of the sub-cover body 1013 to the rear window 103 and the side wall of the box body 1 respectively, so as to simply and quickly fix the sub-cover body 1013 at the rear window 103 of the box body 1.

[0111] In one embodiment, as Figure 4 and Figure 5As shown, the sub-cover body 1013 is further provided with a fifth connection hole 10138. The fifth connection hole 10138 includes a first hole segment 101381 and a second hole segment 101382 which are connected in sequence, the size of the first hole segment 101381 is larger than the size of the second hole segment 101382, and the I-shaped nail 10111 on the cover body 1011 can pass through the first hole segment 101381 and be limited in the second hole segment 101382.

[0112] With such an arrangement, after the operator has installed the sub-cover body 1013, he can place the cover body 1011 on the open box body 1, then pass the I-shaped nail 10111 on the cover body 1011 through the first hole section 101381, and then move the cover body 1011 so that the I-shaped nail 10111 is limited in the second hole section 101382, and finally connect the cover body 1011 to the box body 1, thereby completing the assembly of the cover 101.

[0113] With such a configuration, since the sub-cover body 1013 itself has a smaller area, when using the same material and material thickness, the structural strength of the sub-cover body 1013 itself can be greater than that of the cover plate main body 1011. The sub-cover body 1013 is connected to the cover plate main body 1011, which helps to increase the structural strength of the cover plate main body 1011 and reduce the risk of deformation of the thin sheet-like cover plate main body 1011 without increasing the material thickness of the cover plate 101.

[0114] On this basis, since the cover body 1011 is connected to the sub-cover body 1013 through the cooperation between the fifth connecting hole 10138 and the I-shaped nail 10111, when the devices in the box body 1 need to be maintained, the operator only needs to release the connection between the cover body 1011 and the box body 1, and then move the cover body 1011 so that the I-shaped nail 10111 slides from the first hole section 101381 of the fifth connecting hole 10138 into the second hole section 101382, and the cover body 1011 can be removed, eliminating the step of releasing the connection between the liquid-cooled blind plug connector 2 and the cover body 1011, simplifying the step of disassembling the cover body 1011, and facilitating the maintenance of the devices in the box body 1.

[0115] In one embodiment, Figure 8 As shown, the liquid-cooled blind plug connector 2 further includes a guide sleeve 2025. The guide sleeve 2025 is arranged on the floating module, and the inner circumference of the guide sleeve 2025 has a guide section, and the guide section is arranged with an expanded diameter along the plugging direction of the liquid-cooled blind plug connector 2.

[0116] like Figure 15 and Figure 16As shown, during the process of the chassis 100 being plugged into the cabinet, the guide pins on the cabinet can first come into contact with the guide sleeve 2025, so that the liquid cooling blind plug connector 2 on the chassis 100 can accurately dock with the fluid connector 504 on the cabinet, avoiding damage to the liquid cooling blind plug connector 2. And the guide sleeve 2025 is provided on the adapter joint 202, without occupying the area of the motherboard of the server.

[0117] In one embodiment, as Figure 7 shown, the floating adjustment structure 203 includes a support rod 20311, a floating bolt 2032, a fixing bolt 2033, and a spring 2034. Among them, the support rod 20311 is provided at one side of the base 201. The floating bolt 2032 can pass through the adjustment hole 2013 and connect to the support rod 20311. An adjustment boss 20321 is formed at the root of the screw rod of the floating bolt 2032, and the outer diameter of the adjustment boss 20321 is smaller than the inner diameter of the adjustment hole 2013. An installation hole 2024 is formed on the connection part 2022, and the fixing bolt 2033 passes through the installation hole 2024 and connects to the support rod 20311. The spring 2034 is arranged around the support rod 20311 and is supported between the support rod 20311 and the connection part 2022.

[0118] By setting it in this way, during the process of the chassis 100 of the server being plugged into the cabinet, the fluid connector 504 on the cabinet can act on the adapter joint 202, and make the adapter joint 202 compress the spring 2034, thereby absorbing the manufacturing error of the mechanism end in the axial direction of the adapter joint 202. The adjustment boss 20321 can move in the installation hole 2024, so that the adapter joint 202 floats along its own radial direction, thereby absorbing the manufacturing error of the cabinet end in the radial direction of the adapter joint 202.

[0119] In one embodiment, as Figure 18 shown, the power supply blind plug connector 3 further includes a third floating base 1031 and a power supply plug 1032.

[0120] Among them, the third floating base 1031 is provided at the rear window 103 of the chassis 100. The power supply plug 1032 is provided on the floating base 201 and can float relative to the third floating base 1031 in the vertical or horizontal direction.

[0121] By setting it in this way, during the process of the chassis 100 being plugged into the cabinet, the power supply plug 1032 can float in the vertical or horizontal direction, thereby absorbing the manufacturing tolerance of the cabinet end, so that the power supply blind plug head can accurately dock with the power supply plug 1032 of the cabinet, and the connection is stable and reliable.

[0122] In one embodiment, the third floating base 1031 includes a base body disposed outside the chassis 100. An installation groove is formed on the side facing the chassis 100, and an installation through-hole is formed at the bottom of the installation groove. The power supply plug 1032 is disposed in the installation groove and passes through the installation through-hole. A floating gap 10315 is formed between the power supply plug 1032 and the installation through-hole in the horizontal and vertical directions.

[0123] In one embodiment, the rear window 103 includes a vertical plate and a top plate connected to the vertical plate. The third floating base 1031 further includes a first connecting plate 10311, a first fastening member, a second connecting plate 10313, and a second fastening member.

[0124] Among them, the first connecting plates 10311 are arranged in pairs and are respectively disposed on both sides of the base body in the horizontal direction. First connecting holes 10312 are formed on the first connecting plates 10311. The first fastening member can pass through the first connecting holes 10312 and connect to the vertical plate. The second connecting plate 10313 is connected to the top of the base body, and second connecting holes 10314 are formed on the second connecting plate 10313. The second fastening member can pass through the second connecting holes 10314 and connect to the top plate.

[0125] By setting it in this way, the third floating module can be connected to both the vertical plate and the top plate of the rear window 103 of the chassis 100, which helps to strengthen the structural strength of the rear window 103 of the chassis 100.

[0126] As an alternative embodiment, in an embodiment not shown in one of the drawings, the third floating modules can also be optionally connected to each other by means such as snap connection, bonding, or welding.

[0127] In one embodiment, the power supply plug 1032 has a pair of insertion pieces 10321, and a guiding notch 10322 is formed between the pair of insertion pieces 10321. Along the insertion direction of the insertion pieces 10321, the width of the guiding notch 10322 gradually increases.

[0128] By setting it in this way, during the process of inserting the chassis 100 into the cabinet, the guiding notch 10322 can cooperate with the power supply connector of the chassis 100, thereby guiding the insertion pieces 10321 of the power supply plug 1032 to be accurately inserted into the power supply connector of the chassis 100.

[0129] Among them, the chassis 100 is preferably but not limited to a server chassis and a switch chassis.

[0130] According to an embodiment of the present invention, on the other hand, a cabinet is further provided, which includes a cabinet body and the chassis 100 of a server.

[0131] Inside the cabinet, there are cabinet fluid connectors 504, liquid supply and return manifolds 5, cable trays 603 and power supply bus assemblies 602. The chassis 100 is the chassis 100 provided by the first aspect of the present invention. The liquid cooling blind plug connector 2 of the chassis 100 can be plugged into the fluid connector 504 of the liquid supply and return manifold 5. The power supply blind plug connector 3 of the chassis 100 can be plugged into the power supply connector of the power supply bus assembly 602. The signal blind plug connector 104 of the chassis 100 can be plugged into the signal connector 6034 of the cable tray 603.

[0132] The cabinet of the second aspect of the present invention includes or uses the chassis 100 of the first aspect of the present invention, and thus has its beneficial effects, that is, the connections of the three parts of liquid, electricity and signal between the chassis 100 of the embodiment of the present invention and the cabinet can all adopt blind plug connections. Thus, the numerous pipelines and cables between the traditional cabinet and the chassis 100 are eliminated, enabling the server nodes to be easily deployed inside the cabinet, and being able to solve the defects in the related art that there are numerous pipelines and cables between the chassis 100 and the cabinet, and the installation workload and difficulty of the equipment are high, and being able to achieve one-piece delivery.

[0133] In one embodiment, the liquid supply and return manifold 5 includes a liquid inlet water distributor 501 and a liquid outlet water distributor 502. The liquid inlet water distributor 501 can be plugged into the liquid inlet connector 2a, and the liquid outlet water distributor 502 can be plugged into the liquid outlet connector 2b; the minimum distance between the liquid inlet water distributor 501 and / or the liquid outlet water distributor 502 and the cabinet is d5, and 29 mm ≤ d5 ≤ 49 mm.

[0134] By setting like this, while ensuring the compact internal structure of the cabinet and minimizing the waste of space as much as possible, it can ensure that the gap between the liquid inlet water distributor 501 and the liquid outlet water distributor 502 and the cabinet can allow the power cord to pass through, which is convenient for wiring inside the cabinet.

[0135] In one embodiment, the minimum distance between the liquid inlet water distributor 501 and / or the liquid outlet water distributor 502 and the cabinet is 39.25 mm.

[0136] In one embodiment, the sum of the lengths of the liquid cooling blind plug connector 2 and the cabinet fluid connector 504 in the plugging direction is L1, the sum of the lengths of the signal blind plug connector 104 and the cabinet signal connector 6034 in the plugging direction is L2, and the sum of the lengths of the power supply blind plug connector 3 and the cabinet power supply connector in the plugging direction is L3;

[0137] L1 > L2 > L3.

[0138] With such an arrangement, during the process of plugging the chassis 100 into the cabinet according to the embodiments of the present invention, the liquid cooling blind plug connector 2 can first be plugged into the cabinet fluid connector 504, then the signal blind plug connector 104 is plugged into the cabinet signal connector 6034, and finally, the power supply blind plug connector 3 can be plugged into the cabinet power supply connector.

[0139] The liquid cooling blind plug connector 2 with the highest self - matching accuracy can complete the plugging first, improve the docking accuracy between the chassis 100 and the cabinet, and reduce the error that the liquid cooling blind plug connector 2 needs to absorb.

[0140] In one embodiment, the cabinet signal connector 6034 is a floating connector, which can deflect or float radially along the floating connector when being plugged into the signal blind plug connector 104.

[0141] With such an arrangement, during the process of plugging the chassis 100 into the mechanism, the floating connector can deflect or float radially along the floating connector, so as to absorb the system error.

[0142] On this basis, there are usually dense electrical connectors arranged in the chassis 100 with limited space. Designing the floating structure at the cabinet end can make better use of the space, make the installation and layout of the connectors more flexible, facilitate operation and maintenance in a narrow space, and can reduce signal transmission interference to ensure the accuracy of signal transmission.

[0143] In one embodiment, the chassis 100 further includes a liquid outlet and a fluid collection tank 105.

[0144] Among them, the liquid outlet is arranged at the rear window 103 of the chassis 100. The fluid collection tank 105 is connected to the bottom wall of the chassis 100 and extends outside the rear window 103. A fluid discharge hole 1051 is formed at the bottom of the fluid collection tank 105.

[0145] With such an arrangement, the coolant at the chassis 100 can be discharged into the water receiving tray at the bottom of the cabinet through the fluid collection tank 105 and the fluid discharge hole 1051, thereby preventing the coolant from coming into contact with the electronic devices inside the chassis 100.

[0146] In one embodiment, a liquid leakage detection module is provided in the water receiving tray.

[0147] The liquid leakage detection module can give an alarm when liquid leakage is detected in the water receiving tray. Once the coolant leaks, it may cause a short circuit or damage to the server device. By giving an alarm in time, the operation and maintenance personnel can quickly take measures, such as cutting off the power supply, replacing damaged components, etc., thus avoiding further damage to the device. In key application scenarios such as data centers, the stable operation of the server is crucial. The liquid leakage alarm enables the operation and maintenance personnel to handle the situation before the coolant leakage causes the server to crash, thereby reducing the time and impact of business interruption. Secondly, the coolant leakage may cause an electrical short circuit, which may lead to safety accidents such as fires. The liquid leakage alarm system can detect the leakage in time and notify the relevant personnel, thus taking measures to prevent the occurrence of accidents.

[0148] Among them, the liquid leakage detection module is preferably but not limited to a liquid leakage detection line.

[0149] In one embodiment, a guiding slide rail is provided on the side plate of the cabinet body, and the chassis 100 can be slidably connected to the guiding slide rail, so that the signal blind plug connector 4, the liquid cooling blind plug connector 2 and the power supply blind plug connector 3 can be respectively plugged into the cable tray 603, the liquid supply and return manifold 5 and the power supply bus assembly 602.

[0150] During the assembly process of the chassis 100, the chassis 100 can be placed on the guiding slide rail and slide along the guiding slide rail towards the inside of the cabinet, thereby limiting the movement track of the chassis 100, so that when the chassis 100 moves in place, the signal blind plug connector 4, the liquid cooling blind plug connector 2 and the power supply blind plug connector 3 can be respectively plugged into the cable tray 603, the liquid supply and return manifold 5 and the power supply bus assembly 602.

[0151] In one embodiment, the guiding slide rail includes a connecting edge and a supporting edge.

[0152] Among them, the connecting edge is connected to the side plate. The supporting edge is connected to the bottom of the connecting edge and extends towards the internal space of the cabinet, and can carry the chassis 100.

[0153] The connecting edge and the supporting edge can form a guiding slide rail with an L-shaped cross section. The L-shaped guiding slide rail has a low cost and can facilitate the chassis 100 to be placed on the guiding slide rail from above.

[0154] In one embodiment, the cabinet also includes a first guiding pin 1016 and a second guiding pin 1017.

[0155] Among them, the first guiding pin 1016 is arranged at one side position of the cabinet fluid joint 504 and can be plugged into the guiding sleeve 2025 of the liquid cooling blind plug connector 2. The second guiding pin 1017 is arranged at one side position of the cabinet signal joint 6034 and can be plugged into the guiding block 1043 of the signal blind plug connector 104.

[0156] The above has introduced in detail a chassis 100, a server, and a cabinet provided by the present application. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope required by the present invention.
