Description

Technical Field

[0001] The present application relates to the technical field of mechanism design, and in particular to a chassis and a cabinet. Background Art

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

[0003] However, in the related art, the cooling liquid connection between server nodes, the power supply of server nodes and the signal interconnection between server nodes all need to be connected using pipes or cables, resulting in a large number of pipes and cables that need to be connected between the cabinet and the server nodes. This not only increases the workload and difficulty of cabinet installation, increases the complexity of cabinet operation and maintenance, but also extends the delivery time of the cabinet. Summary of the invention

[0004] The present application provides a chassis and a cabinet to at least solve the problem in the related art that there are many pipes and cables that need to be connected between the cabinet and the server nodes, which increases the workload and difficulty of cabinet installation, increases the complexity of cabinet operation and maintenance, and prolongs the delivery time of the cabinet.

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

[0006] The box has a rear window. The power supply blind plug connector is arranged in the middle of the rear window of the box. The signal blind plug connector includes two groups of signal connectors, which 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, which are respectively arranged on both sides of the signal blind plug connector.

[0007] The present application also provides a cabinet, comprising: The cabinet body is equipped with a supply and return liquid manifold, a cable tray and a power supply busbar assembly; For a chassis such as that provided by 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.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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.

[0016] If the defects of the related technology are not described in detail in the background technology section, the defects of the related technology are analyzed in detail here to introduce this solution.

[0017] The following is combined with Figures 1 to 21 , describing an embodiment of the present invention.

[0018] The embodiment of the present application provides a chassis 100, such as Figure 1 As 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] In one embodiment, Fig. 20As shown, the minimum distance between the liquid inlet connector 2a and / or the liquid outlet connector 2b and the signal connector 1042 along the width direction of the cabinet is d1, and the dimension of the chassis 100 along the width direction of the cabinet is d2; 0.044≤d1 / d2≤0.057.

[0024] 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 larger avoidance gap 10411 on the connector mounting plate 1041 .

[0025] like Fig.21 As shown, since the positions of the connector mounting plate 1041 corresponding to the liquid inlet connector 2a and the liquid outlet connector 2b are provided with an avoidance notch 10411, the liquid inlet connector 2a and the liquid outlet connector 2b are arranged in the avoidance notch 10411. When the minimum distance between the liquid inlet connector 2a and / or the liquid outlet connector 2b and the signal connector 1042 along the cabinet width direction is less than the above range, it will be necessary to open a larger avoidance notch on the connector mounting plate 1041, resulting in a reduction in the volume of the connector mounting plate 1041.

[0026] In a preferred embodiment, d1=27.4 mm, d2=536 mm, and d1 / d2≈0.511.

[0027] The minimum distance between the signal connector 1042 and the power supply blind plug connector 3 along the width direction of the cabinet is d3, and the dimension of the chassis 100 along the width direction of the cabinet is d2; 0.038≤d3 / d2≤0.051.

[0028] 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 plug connector 3 will not collide during the floating process.

[0029] In a preferred embodiment, d3=24.35, d3 / d2≈0.045.

[0030] The distance between the liquid-cooled blind plug connector 2 and one side wall of the chassis 100 along the width direction of the cabinet is d4, and the dimension of the chassis 100 along the width direction of the cabinet is d2; 0.017≤d4 / d2≤0.029.

[0031] Since the power cord needs to pass through the gap between the liquid supply and return manifold 5 and the cabinet to connect to the power supply module of the chassis 100, and the setting position of the liquid supply and return manifold 5 needs to correspond to the liquid inlet connector 2a and the liquid outlet connector 2b, when the minimum distance between the liquid inlet connector 2a and / or the liquid outlet connector 2b and the signal connector 1042 along the width direction of the cabinet exceeds the above range, it is easy to cause difficulty in connecting the power cord to the power supply module of the chassis 100.

[0032] On this basis, the rear window 103 between the signal connector 1042 and the power supply blind plug connector 3, and the rear window 103 between the signal connector 1042 and the liquid cooling blind plug connector 2 can be used to set ventilation holes 106. When the gap between the liquid inlet connector 2a and the signal connector 1042, the gap between the signal connector 1042 and the power supply blind plug connector 3, and the gap between the signal connector 1042 and the liquid outlet connector 2b are within the above range, the ventilation holes can be distributed more evenly on the rear window of the chassis, which will not increase the wind resistance in the chassis, and can help improve the air-cooling and heat dissipation effect of the chassis 100.

[0033] In a preferred embodiment, the sum of the dimensions of the liquid inlet connector 2a and the liquid outlet connector 2b along the width direction of the chassis 100, the sum of the dimensions of the two sets of signal connectors 1042 along the width direction of the chassis 100, and the dimension ratio of the power supply blind plug connector 3 along the width direction of the chassis 100 are: 22~28:54~63:12~18.

[0034] This ratio can reasonably allocate the internal space of the chassis 100 , ensure that the layout of various components in the width direction of the chassis 100 is compact and orderly, avoid space waste or congestion, and improve the space utilization of the chassis 100 .

[0035] In one embodiment, the signal connector 1042 is a high-density connector, and its size along the width direction of the chassis 100 is 130.25 mm, the sum of the sizes of the liquid inlet connector 2a and the liquid outlet connector 2b along the width direction of the chassis 100 is 112 mm, and the size of the power supply blind plug connector 3 along 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 various components in the width direction of the chassis 100 is compact and orderly, avoid space waste or crowding, and improve the space utilization of the chassis 100.

[0036] In one embodiment, Fig.12 As shown, the signal blind-mate connector 104 includes a connector mounting plate 1041 and a signal connector 1042 .

[0037] The connector mounting plate 1041 is connected to the rear window 103. The signal connector 1042 is disposed on the connector mounting plate 1041, and the signal connector 1042 is a high-density connector.

[0038] In one embodiment, the signal blind mate connector 104 further includes a guide block 1043. The guide block 1043 is disposed on the connector mounting plate 1041, and a guide hole 1044 is formed in the guide block 1043. The guide hole 1044 is arranged to expand in diameter along the plugging direction of the signal blind mate connector 104.

[0039] During the plugging process, the guide block 1043 can cooperate with the second guide pin 1017 on the cabinet, so that the signal blind plug connector 104 can be accurately plugged with the cabinet signal connector 6034, and avoid damage to the signal blind plug connector 104 or the cabinet signal connector 6034 caused by misalignment.

[0040] In one embodiment, an air cooling mechanism is further provided in the chassis 100, and a plurality of ventilation holes 106 are provided on the rear window 103 of the chassis 1. Through such a configuration, the chassis 100 of the embodiment of the present invention can simultaneously dissipate heat from the electronic components in the chassis 100 through the air cooling mechanism and the liquid cooling device. The air cooling mechanism can drive the airflow to carry the heat on the electronic components and output it through the ventilation holes 106, thereby ensuring sufficient heat dissipation even when the density of the electronic components in the chassis 100 is high.

[0041] In one embodiment, the guide blocks 1043 are arranged in pairs, and at least one guide block 1043 is respectively disposed at both ends of each group of signal connectors 1042 .

[0042] By such arrangement, the guide block 1043 can limit the signal connector 1042 from both sides of the signal connector 1042, thereby preventing the chassis 100 of the server from tilting during the plug-in process.

[0043] In one embodiment, an avoidance groove 1033 is formed at the rear window 103 , and the liquid-cooling blind plug connector 2 is connected to the bottom wall and / or the side wall of the box body 1 and passes through the avoidance groove 1033 .

[0044] By such a configuration, it is also possible to avoid deformation of the rear window 103 of the chassis 100 due to impact force during the plugging process caused by the liquid-cooled blind plug connector 2 being connected to the rear window 103 of the chassis 100, which helps to strengthen the rigidity of the rear window 103 of the chassis 100.

[0045] As a convertible implementation, in an embodiment not shown in the drawings, the liquid-cooling blind-plug connector 2 is connected to the rear window 103 of the chassis 100 .

[0046] In one embodiment, Figure 6 and Figure 7 As shown, the liquid-cooled blind-plug connector 2 includes a floating module and a quick-connect connector 204 .

[0047] The floating module is connected to the bottom wall and / or side wall of the box body 1. The quick connector 204 is arranged on the floating module and can float along the radial direction and / or axial direction of the quick connector 204 relative to the floating module.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] Furthermore, since the adapter joint 202 itself includes a connecting 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 at the periphery of the connecting portion 2021, so that the adapter joint 202 as a whole floats along the radial and / or axial direction of the connecting joint. This requires a relatively large space to be occupied by the adapter joint 202 during the floating process, and space needs to be reserved in the case 1 for the adapter joint 202 to float. The case 1 of the server of the embodiment of the present invention can reserve more space in the case 1 through the sub-cover body 1013, thereby increasing the floating range of the liquid-cooled blind plug joint 2 and avoiding the collision of the liquid-cooled blind plug joint 2 with the case 1 during the floating process.

[0054] In one embodiment, Figure 2 As shown, the upper side of the avoidance groove 1033 is opened, and the sub-cover 1013 includes a cover body 10131, a first connecting edge 10132 and a second connecting edge 10134. The first connecting edge 10132 and the second connecting edge 10134 are connected to the cover body 10131, and 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 that can be connected 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 that can be connected to the side wall of the box body 1.

[0055] In order to ensure that the rear window 103 of the box body 1 has good structural strength, the box body 1 is prevented from being deformed when subjected to external forces, such as during transportation, collision or improper operation during installation, thereby affecting the overall structural integrity of the box body 1. In the related art, the opening at the rear window 103 of the box body 1 for the liquid-cooled blind plug connector 2 to extend out 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 be easily deformed.

[0056] As a result, in the related art, the installation of the liquid-cooled blind-plug connector 2 is generally performed by obliquely inserting the liquid-cooled blind-plug connector 2 into the box body 1 from the end of the box body 1. During this process, the liquid-cooled blind-plug connector 2 is likely to interfere with the motherboard at the bottom of the box body 1. Therefore, a larger groove needs to be opened on the motherboard to prevent the liquid-cooled blind-plug connector 2 from damaging the motherboard, thereby reducing the area of ​​the motherboard and affecting the functional expansion of the server.

[0057] 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 connector 2 to be installed into the case 1 from top to bottom, avoiding damage to the server's mainboard caused by oblique installation, so that there is no need to set a large groove on the mainboard, which helps to increase the area of ​​the mainboard.

[0058] On this basis, in the embodiments of the present application, Figure 4 and Figure 5 As shown, the cover body 1011 is configured 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 connected to the rear window 103 of the box body 1 and the side wall of the box body 1 respectively. After the sub-cover body 1013 is connected to the box body 1, the first connecting edge 10132 can form a closed through hole together with the avoidance groove 1033 opened on the upper side, and the second connecting edge 10134 can be connected to the side wall of the box body 1, and 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 of the rear window 103.

[0059] Therefore, the case 1 of the server of this embodiment can allow the liquid-cooled blind plug connector 2 to be installed into the case 1 from top to bottom, so as to avoid damage to the server's mainboard due to oblique installation, so that there is no need to set a large groove on the mainboard, which helps to increase the area of ​​the mainboard and will not affect the structural strength of the rear window 103 of the case 1.

[0060] In one embodiment, the sub-cover body 1013 is provided with one of the guide protrusion 10136 and the base guide hole 20111 , and a third connecting hole 10137 .

[0061] The liquid-cooled blind plug connector 2 is provided with the other of the guide protrusion 10136 and the base guide hole 20111, and the fourth connection hole 20112; the guide protrusion 10136 can be limited in the base guide hole 20111, and the third connection hole 10137 is aligned with the fourth connection hole 20112.

[0062] Through such an arrangement, when installing the chassis 100 of the server of the present application, the operator can first install the liquid-cooled blind plug connector 2 on the chassis 1, and then align the guide protrusion 10136 on the sub-cover 1013 with the base guide hole 20111 on the liquid-cooled blind plug connector 2, so that the third connecting hole 10137 and the fourth connecting hole 20112 are aligned, thereby connecting the sub-cover 1013 to the fluid connector 504, and connecting the first connecting edge 10132 and the second connecting edge 10134 of the sub-cover 1013 to the rear window 103 and the side wall of the chassis 1, respectively, thereby simply and quickly fixing the sub-cover 1013 to the rear window 103 of the chassis 1.

[0063] In one embodiment, 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] like Fig.15 and Fig.16As shown, during the plugging process of the chassis 100 and the cabinet, the guide pin on the cabinet can first contact the guide sleeve 2025, so that the liquid-cooled blind plug connector 2 on the chassis 100 can accurately connect with the fluid connector 504 on the cabinet, thereby preventing the liquid-cooled blind plug connector 2 from being damaged. The guide sleeve 2025 is provided on the adapter connector 202, and does not occupy the area of ​​the server motherboard.

[0069] In one embodiment, Figure 7 As shown, the floating adjustment structure 203 includes a support rod 20311, a floating bolt 2032, a fixing bolt 2033 and a spring 2034. The support rod 20311 is arranged at one side of the base 201. The floating bolt 2032 can pass through the adjustment hole 2013 and connect the support rod 20311. The root of the screw of the floating bolt 2032 is formed with an adjustment boss 20321, and the outer diameter of the adjustment boss 20321 is smaller than the inner diameter of the adjustment hole 2013. The connecting part 2022 is formed with a mounting hole 2024, and the fixing bolt 2033 passes through the mounting hole 2024 and connects the support rod 20311. The spring 2034 is arranged around the outside of the support rod 20311 and supported between the support rod 20311 and the connecting part 2022.

[0070] By such arrangement, when the chassis 100 of the server is plugged into the cabinet, the fluid connector 504 on the cabinet can act on the adapter connector 202, and make the adapter connector 202 compress the spring 2034, thereby absorbing the manufacturing error of the mechanism end along the axial direction of the adapter connector 202. The adjustment boss 20321 can move in the mounting hole 2024, so that the adapter connector 202 floats along its own radial direction, thereby absorbing the manufacturing error of the cabinet end along the radial direction of the adapter connector 202.

[0071] In one embodiment, Fig.18 As shown, the power supply blind-plug connector 3 further includes a third floating base 1031 and a power supply plug 1032 .

[0072] The third floating base 1031 is disposed at the rear window 103 of the chassis 100 . The power plug 1032 is disposed on the floating base 201 and can float vertically or horizontally relative to the third floating base 1031 .

[0073] Through such a configuration, during the process of plugging the chassis 100 into the cabinet, the power plug 1032 can float in the vertical or horizontal direction, thereby absorbing the manufacturing tolerance of the cabinet end, so that the power blind plug head can be accurately docked with the cabinet power plug 1032, and the connection is stable and reliable.

[0074] In one embodiment, the third floating base 1031 includes a base body, which is arranged outside the chassis 100 and has a mounting groove formed on the side facing the chassis 100, a mounting through hole is formed at the bottom of the mounting groove, and the power plug 1032 is arranged in the mounting groove and passes through the mounting through hole, and a floating gap 10315 is formed between the power plug 1032 and the mounting through hole in the horizontal and vertical directions.

[0075] In one embodiment, the rear window 103 includes a vertical plate and a top plate connected to the vertical plate, and the third floating base 1031 further includes a first connecting plate 10311 , a first fastener, a second connecting plate 10313 and a second fastener.

[0076] The first connecting plates 10311 are arranged in pairs and are respectively arranged on both sides of the base body in the horizontal direction. The first connecting plates 10311 are formed with first connecting holes 10312. The first fastener 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. The second connecting plate 10313 is formed with second connecting holes 10314. The second fastener can pass through the second connecting holes 10314 and connect to the top plate.

[0077] By such arrangement, the third floating module can be connected to the vertical plate and the top plate of the rear window 103 of the chassis 100 at the same time, which helps to enhance the structural strength of the rear window 103 of the chassis 100 .

[0078] As a convertible implementation, in an embodiment not shown in the drawings, the third floating modules may also be connected to each other by means of clamping, bonding or welding.

[0079] In one embodiment, the power plug 1032 has a pair of plugs 10321 , and a guide notch 10322 is formed between the pair of plugs 10321 . Along the plugging direction of the plugs 10321 , the width of the guide notch 10322 gradually increases.

[0080] By such arrangement, when the chassis 100 is plugged into the cabinet, the guide notch 10322 can cooperate with the power connector of the chassis 100 , thereby guiding the insert 10321 of the power plug 1032 to be accurately plugged into the power connector of the chassis 100 .

[0081] The chassis 100 is preferably, but not limited to, a server chassis and a switch chassis.

[0082] According to an embodiment of the present invention, on the other hand, a cabinet is provided, including a cabinet body and a chassis 100 of a server.

[0083] The cabinet is provided with a cabinet fluid connector 504, a liquid supply and return manifold 5, a cable tray 603 and a power supply bus assembly 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 with 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 with the power supply connector of the power supply bus assembly 602, and the signal blind plug connector 104 of the chassis 100 can be plugged with the signal connector 6034 of the cable tray 603.

[0084] 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, namely, the connections between the chassis 100 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 cabinet and the chassis 100, so that the server nodes can be easily deployed inside the cabinet, and can solve the defects in the related technology that there are many pipes and cables between the chassis 100 and the cabinet, the high installation workload and work difficulty of the equipment, and can achieve integrated delivery.

[0085] In one embodiment, the liquid supply and return manifold 5 includes a liquid inlet water divider 501 and a liquid outlet water divider 502, the liquid inlet water divider 501 can be plugged into the liquid inlet connector 2a, and the liquid outlet water divider 502 can be plugged into the liquid outlet connector 2b; the minimum distance between the liquid inlet water divider 501 and / or the liquid outlet water divider 502 and the cabinet is d5, 29mm≤d5≤49mm.

[0086] By such an arrangement, the internal structure of the cabinet can be kept compact, space waste can be minimized, and at the same time, the gap between the liquid inlet water divider 501 and the liquid outlet water divider 502 and the cabinet can be provided for the power cord to pass through, which can facilitate wiring inside the cabinet.

[0087] In one embodiment, the minimum distance between the liquid inlet water separator 501 and / or the liquid outlet water separator 502 and the cabinet is 39.25 mm.

[0088] In one embodiment, the sum of the lengths of the liquid cooling blind plug connector 2 and the cabinet fluid connector 504 along the plugging direction is L1, the sum of the lengths of the signal blind plug connector 104 and the cabinet signal connector 6034 along 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 along the plugging direction is L3; L1>L2>L3.

[0089] Through such an arrangement, when the chassis 100 of the cabinet of the embodiment of the present invention is plugged into the cabinet, the liquid cooling blind plug connector 2 can be plugged into the cabinet fluid connector 504 first, then the signal blind plug connector 104 can be 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.

[0090] The liquid-cooled blind-plug connector 2 with the highest matching accuracy can complete the plug-in first, improve the docking accuracy between the chassis 100 and the cabinet, and reduce the error that the liquid-cooled blind-plug connector 2 needs to absorb.

[0091] In one embodiment, the cabinet signal connector 6034 is a floating connector, which can be deflected or floated along the radial direction of the floating connector when plugged with the signal blind plug connector 104 .

[0092] By such arrangement, during the process of the chassis 100 being inserted into the mechanism, the floating joint can be deflected or float along the radial direction of the floating joint, thereby absorbing the system error.

[0093] On this basis, the chassis 100 is usually filled with densely packed electrical connectors and the space is limited. Designing the floating structure at the cabinet end can make better use of the space, make the installation and layout of the connector more flexible, facilitate operation and maintenance in a small space, and reduce signal transmission interference to ensure the accuracy of signal transmission.

[0094] In one embodiment, the chassis 100 further includes a liquid outlet and a fluid collection tank 105 .

[0095] The liquid outlet is disposed at the rear window 103 of the chassis 100 . The fluid collecting tank 105 is connected to the bottom wall of the chassis 100 and extends out of the rear window 103 . A fluid discharge hole 1051 is formed at the bottom of the fluid collecting tank 105 . By such arrangement, the cooling liquid in the chassis 100 can be discharged into the water receiving tray at the bottom of the cabinet through the fluid collecting groove 105 and the fluid discharge hole 1051 , thereby preventing the cooling liquid from contacting the electronic components inside the chassis 100 .

[0096] In one embodiment, a liquid leakage detection module is provided in the water receiving tray.

[0097] The leakage detection module can alarm when it detects leakage in the water tray. Once the coolant leaks, it may cause a short circuit or damage to the server equipment. Through timely alarm, operation and maintenance personnel can quickly take measures, such as cutting off the power supply, replacing damaged parts, etc., to avoid further damage to the equipment. In critical application scenarios such as data centers, the stable operation of servers is crucial. The leakage alarm allows operation and maintenance personnel to deal with the coolant leakage before it causes the server to shut down, thereby reducing the time and impact of business interruptions. Secondly, coolant leakage may cause electrical short circuits, leading to safety accidents such as fire. The leakage alarm system can detect leaks in time and notify relevant personnel, so that measures can be taken to prevent accidents.

[0098] The liquid leakage detection module is preferably but not limited to a liquid leakage detection line.

[0099] In one embodiment, a guide rail is provided on the side panel of the cabinet, and the chassis 100 can be slidably connected to the guide 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 with the cable tray 603, the supply and return liquid manifold 5 and the power supply bus assembly 602.

[0100] During the assembly process of the chassis 100, the chassis 100 can be placed on the guide rail and slide along the guide rail toward the inside of the cabinet, thereby limiting the movement trajectory of the chassis 100, so that when the chassis 100 moves into 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 connected to the cable tray 603, the supply and return liquid manifold 5 and the power supply bus assembly 602.

[0101] In one embodiment, the guide rail includes a connecting edge and a supporting edge.

[0102] The connecting edge is connected to the side plate, and the supporting edge is connected to the bottom of the connecting edge and extends toward the inner space of the cabinet, so as to support the chassis 100 .

[0103] The connecting edge and the supporting edge can form a guide rail with an L-shaped cross-section. The L-shaped guide rail has a low cost and can facilitate the chassis 100 to be placed on the guide rail from above.

[0104] In one embodiment, the cabinet further includes a first guide pin 1016 and a second guide pin 1017 .

[0105] The first guide pin 1016 is disposed on one side of the cabinet fluid connector 504 and can be plugged with the guide sleeve 2025 of the liquid cooling blind plug connector 2. The second guide pin 1017 is disposed on one side of the cabinet signal connector 6034 and can be plugged with the guide block 1043 of the signal blind plug connector 104.

[0106] The above is a detailed introduction to a chassis 100, a server and a cabinet provided by the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection required by the present invention.
