Description

Technical Field

[0001] The present invention relates to the technical field of mechanism design, and in particular to a chassis, a liquid cooling system and a cabinet of a server. Background Art

[0002] A server cabinet is an installation box that is used to combine installation panels, plug-ins, plug-in boxes, electronic components, devices and mechanical parts and components to form an integral whole.

[0003] In the related art, the server node is connected to the fluid joint on the artificial intelligence cabinet through a liquid-cooled blind-plug joint. The liquid-cooled blind-plug joint can float radially or axially along the fluid joint relative to the chassis of the server node to compensate for errors during the installation process. However, the liquid-cooled blind-plug joint is prone to collide with the cover of the chassis during the floating process, affecting the floating range of the liquid-cooled blind-plug joint. Summary of the invention

[0004] The present application provides a server chassis, a liquid cooling system and a cabinet to at least solve the problem in the related art that the liquid cooling blind plug connector of the server is prone to collide with the cover of the chassis during the floating process, thereby affecting the floating range of the liquid cooling blind plug connector.

[0005] The present application provides a server chassis, including: A box body, a cover plate is provided on one side of the box body, the cover plate includes a cover plate body and a sub-cover body, a notch is formed on one side of the cover plate body close to the rear window of the box body, the sub-cover body is detachably arranged at the notch, the distance between the sub-cover body and the first wall of the box body is greater than the distance between the cover plate body and the first wall, and the first wall and the cover plate are arranged opposite to each other; The liquid-cooled blind plug connector is disposed at the rear window of the box body and is located between the sub-cover body and the first wall, and can float along the radial direction and / or axial direction of the liquid-cooled blind plug connector.

[0006] The present application also provides a liquid cooling system, comprising: A liquid supply and return manifold, wherein the liquid supply and return manifold has a plurality of branch pipes, and each branch pipe is provided with a fluid connector; The first aspect of the present invention provides a server chassis, wherein the liquid cooling blind plug connector of the chassis is used to be plugged with a fluid connector.

[0007] The present application also provides a cabinet, comprising: The cabinet body is provided with a liquid supply and return manifold, the liquid supply and return manifold has a plurality of branch pipes, and the branch pipes are connected with fluid joints; The server chassis provided in the first aspect of the present invention is arranged in a cabinet, and the liquid cooling blind plug connector of the chassis is plugged into the fluid connector.

[0008] Through the present application, since the chassis of the server of the embodiment of the present invention is in use and during the plugging process, the liquid-cooled blind plug connector can allow the plug-in component to float radially and / or axially of the liquid-cooled blind plug connector, thereby absorbing the manufacturing tolerance of the cabinet end, so that the liquid-cooled blind plug connector can be accurately docked with the fluid connector on the cabinet, and ensure that the connection between the liquid-cooled blind plug connector and the fluid connector on the cabinet is reliable and leak-free.

[0009] Furthermore, because the distance between the sub-cover body and the first wall of the box body is greater than the distance between the cover body main body and the first wall, during the floating process of the liquid-cooled blind plug connector, the sub-cover body can reduce the risk of the liquid-cooled blind plug connector colliding with the cover plate of the box body, thereby increasing the floating range of the liquid-cooled blind plug connector and helping to ensure that the connection between the liquid-cooled blind plug connector and the fluid connector on the cabinet is more reliable.

[0010] On this basis, since the area of ​​the sub-cover itself is smaller, when using the same material and material thickness, the structural strength of the sub-cover itself can be greater than the cover body. The sub-cover is connected to the box body and the cover body, which helps to increase the structural strength of the box rear window and the cover body.

[0011] Therefore, the chassis of the embodiment of the present invention can reduce the risk of the liquid-cooled blind-plug connector colliding with the cover of the chassis during the floating process, increase the floating range of the liquid-cooled blind-plug connector, help ensure that the connection between the liquid-cooled blind-plug connector and the fluid connector on the cabinet is more reliable, and help increase the structural strength of the chassis rear window and the cover body.

[0012] The liquid cooling system of the second aspect of the present invention includes or uses the chassis of the server of the first aspect of the present invention, and thus has its beneficial effects, namely: it can reduce the risk of the liquid-cooled blind plug connector colliding with the cover of the chassis during the floating process, increase the floating range of the liquid-cooled blind plug connector, help ensure that the connection between the liquid-cooled blind plug connector and the fluid connector on the cabinet is more reliable, and help increase the structural strength of the chassis rear window and the cover body.

[0013] The cabinet of the third 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: it can reduce the risk of the liquid-cooled blind plug connector colliding with the cover plate of the chassis during the floating process, increase the floating range of the liquid-cooled blind plug connector, help ensure that the connection between the liquid-cooled blind plug connector and the fluid connector on the cabinet is more reliable, and help increase the structural strength of the rear window of the chassis and the cover plate body.

[0019] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Combine the following Figures 1 to 28 , describing an embodiment of the present invention.

[0021] According to an embodiment of the present invention, on the one hand, a chassis of a server is provided, such as Figures 1 to 4 As shown, it includes a box body 1 and a liquid-cooled blind plug connector 2.

[0022] A cover plate 101 is provided on one side of the box body 1. 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. 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.

[0023] During use of the chassis of the server of the embodiment of the present invention, during the plugging process, the liquid-cooled blind plug connector 2 can allow the plug-in component to float along the radial and / or axial direction of the liquid-cooled blind plug connector 2, 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.

[0024] Furthermore, because 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, thereby increasing the floating range of the liquid-cooled blind plug connector 2 and helping to ensure that the connection between the liquid-cooled blind plug connector 2 and the fluid connector 504 on the cabinet is more reliable.

[0025] 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.

[0026] Therefore, the chassis of the embodiment of the present invention can reduce the risk of the liquid-cooled blind plug connector 2 colliding with the cover plate 101 of the chassis 1 during the floating process, increase the floating range of the liquid-cooled blind plug connector 2, help ensure that the connection between the liquid-cooled blind plug connector 2 and the fluid connector 504 on the cabinet is more reliable, and help increase the structural strength of the rear window 103 of the chassis 1 and the cover plate main body 1011.

[0027] In one embodiment, the first wall 102 can be selected as the bottom wall of the box body 1, the cover body is the upper cover of the box body 1, and the sub-cover body 1013 can be used to increase the floating range of the liquid-cooled blind plug connector 2 in the vertical direction.

[0028] As a convertible embodiment, in an embodiment not shown in the accompanying drawings, the first wall 102 is the top wall of the box body 1, the cover body is the lower cover of the box body 1, and the sub-cover body 1013 can be used to increase the floating range of the liquid-cooled blind plug connector 2 in the vertical direction.

[0029] As another convertible embodiment, in another embodiment not shown in the accompanying drawings, the first wall 102 is a side wall of the box body 1, and the cover body is detachably covered on the side opposite to the box body 1 and the first wall 102, and the sub-cover body 1013 can be used to increase the floating range of the liquid-cooled blind plug connector 2 in the horizontal direction.

[0030] In one embodiment, Figure 7 and Figure 8 As shown, the liquid-cooled blind plug connector 2 includes a base 201, an adapter connector 202, and a floating adjustment structure 203. The base 201 is connected to the housing 1, and a connector through hole 2012 and an adjustment hole 2013 are formed on the base 201. The adapter connector 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 connector 202 can float relative to the housing 1 along the axial direction of the adapter connector 202.

[0031] like Fig. 9 and Fig.10 As shown, 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 joint is connected to the connecting portion 2022 at the outer 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 larger 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 in 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.

[0032] In one embodiment, Fig.10 As shown, a water-cooling pipe mounting pagoda head is formed on the connecting pipe portion 2021, which can be used to connect the water-cooling pipe.

[0033] As an alternative implementation, in an embodiment not shown in the drawings, the quick-connect connector 204 directly passes through the adapter connector 202 .

[0034] In one embodiment, Figure 2 As described, a avoidance groove 1031 with an upper opening is formed on the rear window 103 of the box body 1, the liquid-cooling blind plug connector 2 is arranged in the box body 1 and passes through the avoidance groove 1031, 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 that can be connected to the rear window 103, and 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.

[0035] In order to ensure that the rear window 103 of the box body 1 has good structural strength and prevent the box body 1 from being deformed when subjected to external forces, such as due to improper operation during transportation, collision or 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.

[0036] 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.

[0037] The chassis of the server in the embodiment of the present application is provided with an avoidance groove 1031 with an upper opening at the rear window 103, which enables the liquid-cooled blind plug connector 2 to be installed into the box body 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.

[0038] On this basis, in the embodiments of the present application, Figure 5 and Figure 6As 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 1031 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 on 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.

[0039] 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 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.

[0040] In one embodiment, the first connection portion 10133 is a first connection hole, and the box body 1 further includes a first fastener, which can pass through the first connection hole and connect to the rear window 103 of the box body 1; and / or, The second connection portion 10135 is a second connection hole. The box body 1 further includes a second fastener, which can pass through the second connection hole and connect to the side wall of the box body 1.

[0041] The first fastener and the second fastener preferably include, but are not limited to, bolts or rivets.

[0042] In one embodiment, a positioning pin is provided on the second connecting edge 10134 of the sub-cover body 1013, and a positioning notch 1012 is provided on the side wall of the box body 1. When the sub-cover body 1013 is covered on the liquid-cooled blind plug connector 2, the positioning pin can be limited in the positioning notch 1012, and the first connecting hole is aligned with the hole position on the box body 1, so that the sub-cover body 1013 is guided and limited by the positioning pin, and it is convenient for the operator to use fasteners to connect the second connecting edge 10134 to the side wall of the box body 1.

[0043] The fastener is preferably, but not limited to, a bolt or a rivet, etc. The positioning pin is preferably, but not limited to, an I-shaped nail 10111.

[0044] As a convertible implementation, in an embodiment not shown in the accompanying drawings, the connection between the first connecting portion 10133 and the rear window 103 of the box body 1, and the connection between the second connecting portion 10135 and the side wall of the box body 1 can also be optionally snapped or bonded.

[0045] In one embodiment, Figure 5 , Figure 6 , Fig.13 and Fig.14 As shown, the sub-cover body 1013 is provided with one of the guide protrusion 10136 and the guide hole 20111 , and a third connecting hole 10137 .

[0046] The liquid-cooled blind plug connector 2 is provided with the other of the guide protrusion 10136 and the guide hole 20111, and a fourth connecting hole 20112; the guide protrusion 10136 can be limited in the guide hole 20111, and the third connecting hole 10137 is aligned with the fourth connecting hole 20112.

[0047] Through such an arrangement, when installing the chassis 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 body 1013 with the 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 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 chassis 1, respectively, thereby simply and quickly fixing the sub-cover body 1013 at the rear window 103 of the chassis 1.

[0048] In one embodiment, an upper connecting plate 2011 is formed on the liquid-cooled blind plug connector 2, a guide hole 20111 and a fourth connecting hole 20112 are formed on the upper connecting plate 2011, and a guide protrusion 10136 and a third connecting hole 10137 are formed on the sub-cover body 1013.

[0051] In one embodiment, Figure 5 and Figure 6 As 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.

[0052] 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.

[0053] 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.

[0054] 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 electronic components 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 components in the box body 1.

[0055] In one embodiment, Fig.11 and Fig.12 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.

[0056] By such arrangement, when the chassis 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.

[0057] The difference between the inner diameter of the adjustment hole 2013 and the outer diameter of the adjustment boss 20321 can be set according to the cumulative manufacturing tolerance of the cabinet to ensure that the floating range of the liquid-cooled blind plug connector 2 is sufficient to absorb the cumulative manufacturing tolerance of the cabinet.

[0058] For example, in an optional embodiment, the difference between the inner diameter of the adjustment hole 2013 and the outer diameter of the adjustment boss 20321 can be selected to be 2 to 6 times the cumulative manufacturing tolerance of the cabinet.

[0059] The cumulative tolerance of cabinet manufacturing refers to the deviation between the overall size and performance of the cabinet and the design requirements due to the accumulation of manufacturing errors and assembly errors of various components during the cabinet manufacturing process, which is well known to those skilled in the art.

[0060] Exemplarily, in an optional embodiment, the cumulative tolerance for cabinet manufacturing may be selected to be 2 mm.

[0061] In one embodiment, Fig.10 As shown, the dimension of the adjusting boss 20321 along the axial direction of the adapter joint 202 is greater than the thickness of the supporting plate 2014 of the base 201, which can prevent the supporting rod 20311 from being locked on the supporting plate 2014 when the floating bolt 2032 is connected to the supporting rod 20311, thereby preventing the liquid-cooled blind plug joint 2 from floating along the radial direction of the adapter joint 202.

[0062] In one embodiment, an anti-collision boss 2023 is formed on one side of the adapter joint 202 facing the fluid joint 504 of the cabinet, the connecting pipe portion 2021 is arranged at a corresponding position of the anti-collision boss 2023 , and the mounting hole 2024 is spaced apart from the anti-collision boss 2023 .

[0063] In one embodiment, the inner circumference of the adapter joint 202 is formed with an internal thread, which can be used to connect the quick connector 204. The provision of the anti-collision boss 2023 can not only be used to increase the axial dimension of the internal thread to make the connection between the quick connector and the adapter joint 202 more stable, but also ensure that when the adapter joint 202 compresses the spring 2034 and the support rod 20311 protrudes from the surface of the adapter joint 202, the support rod 20311 is still farther away from the cabinet than the anti-collision boss 2023, thereby avoiding collision between the support rod 20311 and the cabinet.

[0064] As an alternative implementation, in an embodiment not shown in the drawings, the quick-connect fitting 204 is interference-fitted inside the adapter fitting 202 .

[0065] As a convertible implementation, in an embodiment not shown in the drawings, an anti-collision groove is formed on the side of the adapter joint 202 facing the fluid joint 504 of the cabinet, and the mounting hole 2024 is provided at the bottom of the anti-collision groove.

[0066] By such arrangement, when the adapter joint 202 compresses the spring 2034, the support rod 20311 can still be located in the anti-collision groove, thereby preventing the support rod 20311 from protruding from the surface of the adapter joint 202 and colliding with the cabinet.

[0067] In one embodiment, the liquid-cooled blind plug connector 2 includes two support rod groups 2031 , which are respectively arranged on both sides of the connecting pipe portion 2021 , and each support rod group 2031 includes at least two support rods 20311 .

[0068] As a convertible implementation, in an embodiment not shown in the drawings, the number of support rods 20311 can also be selected to be an odd number, such as three or five, and are arranged at intervals along the circumference of the adapter joint 202.

[0069] In one embodiment, the support rod set 2031 further includes a connecting rod 20312. The connecting rod 20312 is connected between the two support rods 20311, and a side of the connecting rod 20312 facing the connecting pipe portion 2021 is formed with an avoidance groove 20313.

[0070] The setting of the avoidance groove 20313 can allow the size of the connecting pipe portion 2021 to be set larger without increasing the size of the base 201 and the adapter 202, which helps to increase the flow rate of the coolant and improve the heat dissipation efficiency.

[0071] In one embodiment, a friction reducing layer is formed between the connecting rod 20312 and the connecting portion 2022 .

[0072] The friction-reducing layer can reduce the friction resistance between the connecting rod 20312 and the connecting portion 2022, so that the floating of the adapter joint 202 is smoother.

[0073] In one embodiment, the friction reducing layer is a Mylar sheet attached to a side of the connecting rod 20312 close to the connecting portion 2022 . As a convertible embodiment, the friction-reducing layer may also be a lubricating oil layer formed between the connecting rod 20312 and the connecting portion 2022 .

[0074] In one embodiment, Fig.13 and Fig.14 As shown, the base 201 includes a supporting upright plate 2014 and a connecting bottom plate 2015. The connecting bottom plate 2015 is connected to the bottom of the supporting upright plate 2014 and is used to connect to the bottom wall of the box body 1.

[0075] The connecting base plate 2015 is connected to the bottom wall of the box 1, which can prevent the liquid cooling blind plug connector 2 from being set at the rear window 103 of the box 1, resulting in deformation or damage of the rear window 103 of the box 1 during the plugging process of the box 1 and the fluid connector 504 of the cabinet.

[0076] In one embodiment, the connecting bottom plate 2015 and the supporting vertical plate 2014 can form an L-shaped base 201, and the connecting bottom plate 2015 is connected to the side of the supporting vertical plate 2014 away from the adapter joint 202, which can avoid interference between the adapter joint 202 and the connecting bottom plate 2015 during the floating process.

[0077] In one embodiment, a avoiding groove 20151 is formed on the connecting bottom plate 2015 at a position corresponding to the floating bolt 2032 .

[0078] The avoidance groove 20151 can provide more floating space for the lower part of the floating bolt 2032 below the floating bolt 2032, thereby preventing the floating bolt 2032 from interfering with the connecting base plate 2015 when floating downward, and can expand the floating range of the liquid-cooled blind plug joint 2 in the vertical direction without increasing the size of the liquid-cooled blind plug joint 2 in the vertical direction, and can reduce the weight of the base 201 and help reduce the material required for the base 201.

[0079] The avoidance groove 20151 is preferably but not limited to being formed by removing part of the material on the connecting base plate 2015 .

[0080] In one embodiment, arc chamfers are formed at the edges of the supporting vertical plate 2014 and the connecting bottom plate 2015 to prevent the floating blind plug connector from scratching the electronic devices inside the box 1 during the assembly process.

[0081] In one embodiment, the base 201 further includes a reinforcing rib 2016. The reinforcing rib 2016 is connected between the supporting upright plate 2014 and the connecting bottom plate 2015.

[0082] By such arrangement, the reinforcing ribs 2016 can enhance the connection strength between the connecting bottom plate 2015 and the connecting side plate 2017 , thereby increasing the floating range of the liquid-cooled blind plug connector 2 without affecting the rigidity of the base 201 itself.

[0083] Preferably, the reinforcing rib 2016 is arranged along the vertical direction and is located between two adjacent joint through holes 2012. By such an arrangement, interference between the floating bolt 2032 and the reinforcing rib 2016 can be avoided.

[0084] In one embodiment, the base 201 includes a connecting side plate 2017. The connecting side plate 2017 is connected to one side of the supporting vertical plate 2014, and is used to be connected to the side wall of the box body 1.

[0085] The connecting side plate 2017 can connect the liquid-cooled blind plug connector 2 to the side wall of the box body 1, so that the liquid-cooled blind plug connector 2 can be connected to the bottom wall and the side wall of the box body 1 at the same time, further strengthening the structural strength of the rear window 103 of the box body 1.

[0086] The connection between the connecting side plate 2017 and the supporting vertical plate 2014 is preferably, but not limited to, a snap connection, a riveted connection or a bolt connection.

[0087] In one embodiment, a concave abutment groove 104 is formed on the side wall of the box body 1, and the abutment groove 104 is used to abut against the cover plate 101 of the box body 1. A guide slope 20171 is formed on the upper part of the connecting side plate 2017, and from bottom to top, the guide slope 20171 is inclined toward the middle position of the box body 1.

[0088] The design of the abutment groove 104 can increase the connection area between the side wall of the box body 1 and the cover plate 101, making the combination of the two tighter and more stable, improving the overall structural strength of the box body 1, and reducing deformation or damage caused by external forces. On this basis, since the abutment groove 104 is concave, the gap between the liquid-cooled blind plug connector 2 and the floating module is narrow, and the guide slope 20171 can facilitate the liquid-cooled blind plug connector 2 to be slightly tilted when it is placed in the box body 1 to avoid the abutment groove 104, and will not cause it to get stuck.

[0089] In one embodiment, the liquid-cooled blind plug connector 2 further comprises a guide sleeve 2025. The guide sleeve 2025 is disposed on the adapter connector 202, and a guide section is formed on the inner periphery of the guide sleeve 2025. Along the plugging direction of the liquid-cooled blind plug connector 2, the inner diameter of the guide sleeve 2025 gradually decreases.

[0090] During the plugging process between the box body 1 and the cabinet, the guide pin on the cabinet can first contact the guide sleeve 2025, so that the liquid cooling blind plug connector 2 on the box body 1 can accurately connect with the fluid connector 504 on the cabinet, thereby preventing the liquid cooling blind plug connector 2 from being damaged. The guide sleeve 2025 is arranged on the adapter connector 202, and does not occupy the area of ​​the server motherboard.

[0091] As a convertible implementation, in an embodiment not shown in the accompanying drawings, the guide structure between the liquid-cooled blind plug connector 2 and the cabinet can also be selected as the cooperation of the guide pin and the guide hole 20111, etc.

[0092] In one embodiment, Figure 3 Hehe Figure 4 As shown, the box body 1 further includes a liquid outlet 1032 and a fluid collecting groove 105. The liquid outlet 1032 is provided at the rear window 103 of the box body 1. The fluid collecting groove 105 is connected to the bottom wall of the box body 1 and extends outside the rear window 103. A fluid discharge hole 1051 is formed at the bottom of the fluid collecting groove 105.

[0093] By such arrangement, when there is leakage between the liquid-cooled blind plug connector 2 and the fluid connector 504 , the leaked coolant can be discharged in sequence through the liquid outlet 1032 , the fluid collecting groove 105 and the fluid discharge hole 1051 , thereby preventing the coolant from contacting the electronic components inside the housing 1 .

[0094] In a preferred embodiment, the fluid discharge hole 1051 is connected to a water tray, which is used to discharge the coolant. A leakage detection line is provided in the water tray, which can alarm when a leak is detected 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 key application scenarios such as data centers, the stable operation of the server 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 fires. The leakage alarm system can detect leaks in time and notify relevant personnel, so that measures can be taken to prevent accidents.

[0095] In one embodiment, the liquid-cooled 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 disposed at two ends of the rear window 103 of the housing 1 .

[0096] By such a configuration, it is possible to ensure that both ends of the box body 1 are evenly stressed during blind insertion, thereby preventing the liquid cooling blind plug connector 2 from being concentrated on one side, causing the box body 1 to be stressed sideways during insertion into the cabinet, thereby damaging the liquid cooling blind plug connector 2 and the fluid connector 504. 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 to be thicker, thereby improving the liquid cooling effect.

[0097] In one embodiment, Fig.21 As shown, the chassis of the server further includes a power supply blind plug connector 3 and a signal blind plug connector 4. The power supply blind plug connector 3 is disposed at the rear window 103 of the box body 1 and is located in the middle of the rear window 103. The signal blind plug connector 4 is disposed at the rear window 103 of the box body 1, and the signal blind plug connector 4 is divided into two groups and is disposed at two sides of the power supply blind plug connector 3 respectively.

[0098] With the rapid development of artificial intelligence technology, the scale and power density of data centers continue to rise. Liquid cooling has gradually replaced air cooling with its advantages such as low noise and low energy consumption, and is increasingly widely used in cabinet products, especially high-density artificial intelligence server cabinet products.

[0099] In the related art, the liquid cooling blind plug connector 2 of the server cabinet is installed by the operation and maintenance personnel directly connecting the liquid cooling pipe at the cabinet rear window 103. On the one hand, the liquid cooling pipe occupies a large space, resulting in the need to reserve operating space for the operation and maintenance personnel at the cabinet rear window 103, which easily affects the density of the server, and the cables that need to be installed are complicated, resulting in low installation and maintenance efficiency.

[0100] However, the server liquid cooling blind plug technology faces the challenges of tolerance and guidance problems in the actual use process. The connection between the server chassis and the cabinet, including liquid, electricity and signal, can all be blind plugged, 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.

[0101] On this basis, the power supply blind-plug connector 3 is arranged in the middle of the box body 1, which can help the installation force of the server box body 1, and the signal blind-plug connectors are arranged on both sides of the power supply blind-plug connector 3, which can not only make the force of the box body 1 more uniform during the blind plugging process, but also improve the smoothness of the signal routing in the signal connector mounting plate 401. In one embodiment, Fig.24 and Fig.25 As shown, the signal blind-mate connector 4 includes a connector mounting plate 401 and a signal connector 402 .

[0102] The connector mounting plate 401 is connected to the rear window 103 . The signal connector 402 is disposed on the connector mounting plate 401 .

[0103] In one embodiment, the signal blind mate connector 4 further includes a guide block 403. The guide block 403 is disposed on the connector mounting plate 401, and a guide through hole 404 is formed in the guide block 403. The guide through hole 404 is expanded in diameter along the plugging direction of the signal blind mate connector 4.

[0104] During the plugging process, the guide block 403 can cooperate with the wire pin on the cabinet, so that the signal blind plug connector 4 can be accurately plugged with the cabinet signal connector 603, and avoid damage to the signal blind plug connector 4 or the cabinet signal connector 603 caused by misalignment.

[0105] In one embodiment, the guide blocks 403 are arranged in pairs, and at least one guide block 403 is respectively arranged at both ends of each group of signal connectors 402 .

[0106] By such arrangement, the guide block 403 can limit the signal connector 402 from both sides of the signal connector 402, thereby preventing the chassis of the server from tilting during the plug-in process.

[0107] 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 box body 1 .

[0108] In one embodiment, Fig.26 and Fig. 27 As shown, the power supply blind-plug connector 3 further includes a third floating base 301 and a power supply plug 302 .

[0109] The third floating base 301 is disposed at the rear window 103 of the box body 1. The power plug 302 is disposed on the floating base 201 and can float vertically or horizontally relative to the third floating base 301.

[0110] Through such an arrangement, during the process of plugging the box body 1 into the cabinet, the power plug 302 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 302, and the connection is stable and reliable.

[0111] In one embodiment, the third floating base 301 includes a base body, which is arranged outside the box body 1 and has a mounting groove formed on one side facing the box body 1, a mounting through hole is formed at the bottom of the mounting groove, and the power plug 302 is arranged in the mounting groove and passes through the mounting through hole, and a floating gap 3015 is formed between the power plug 302 and the mounting through hole in the horizontal and vertical directions.

[0112] 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 301 further includes a first connecting plate 3011 , a first fastener, a second connecting plate 3013 and a second fastener.

[0113] The first connecting plates 3011 are arranged in pairs and are respectively arranged on both sides of the base body in the horizontal direction, and the first connecting plates 3011 are formed with a sixth connecting hole 3012. The first fastener can pass through the sixth connecting hole 3012 and connect to the vertical plate. The second connecting plate 3013 is connected to the top of the base body, and the second connecting plate 3013 is formed with a seventh connecting hole 3014. The second fastener can pass through the seventh connecting hole 3014 and connect to the top plate.

[0114] 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 box body 1 at the same time, which helps to enhance the structural strength of the rear window 103 of the box body 1 .

[0115] 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.

[0116] In one embodiment, Fig.26 As shown, the power plug 302 has a pair of inserting blades 3021 , and a guide notch 3022 is formed between the pair of inserting blades 3021 . Along the plugging direction of the inserting blades 3021 , the width of the guide notch 3022 gradually increases.

[0117] By such arrangement, when the box 1 is plugged into the cabinet, the guide notch 3022 can cooperate with the power connector of the box 1, thereby guiding the insert piece 3021 of the power plug 302 to be accurately plugged into the power connector of the box 1.

[0118] According to an embodiment of the present invention, on the other hand, a liquid cooling system is provided, comprising a liquid supply and return manifold 5 and a chassis. A fluid connector 504 is connected to the branch pipe 503 of the liquid supply and return manifold 5. The chassis is a chassis of the server provided in the first aspect of the present invention, and the liquid cooling blind plug connector 2 of the chassis is used to be plugged with the fluid connector 504.

[0119] The liquid cooling system transports the cooled coolant to the supply and return liquid manifold 5 through the cooling capacity distribution module, and the manifold distributes the coolant to the cold plates of various liquid cooling devices (such as servers, switches, etc.). After the coolant absorbs the heat generated by the equipment in the cold plate, it flows back to the supply and return liquid manifold 5 through the liquid cooling blind plug connector 2, and finally returns to the cooling capacity distribution module for re-cooling and circulation. Liquid cooling systems are widely used in data centers, server rooms and other places that require efficient heat dissipation. With the development of cloud computing, big data, artificial intelligence and other technologies, the power density of data centers continues to rise, and traditional air cooling technology is difficult to meet the heat dissipation needs of high-power components. Liquid cooling technology, with its efficient heat dissipation capabilities, has become an effective means to reduce the energy efficiency of data centers. As one of the core components of the liquid cooling system, the liquid cooling system is crucial to ensure the normal operation and heat dissipation effect of the liquid cooling system.

[0120] The liquid cooling system of the second aspect of the present invention includes or uses the chassis of the server of the first aspect of the present invention, and thus has its beneficial effects, namely: it can reduce the risk of the liquid-cooled blind plug connector 2 colliding with the cover plate 101 of the box body 1 during the floating process, increase the floating range of the liquid-cooled blind plug connector 2, help ensure that the connection between the liquid-cooled blind plug connector 2 and the fluid connector 504 on the cabinet is more reliable, and help increase the structural strength of the rear window 103 of the box body 1 and the cover plate main body 1011.

[0121] According to an embodiment of the present invention, on the other hand, a cabinet is provided, including a cabinet body and a chassis. A liquid supply and return manifold 5 and a fluid connector 504 are provided in the cabinet body, and the fluid connector 504 is connected to a branch pipe 503 of the liquid supply and return manifold 5. The chassis is a chassis of a server provided in the first aspect of the present invention, which is provided in the cabinet body, and a liquid cooling blind plug connector 2 of a server node is plugged into the fluid connector 504.

[0122] The cabinet of the third 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: it can reduce the risk of the liquid-cooled blind plug connector 2 colliding with the cover plate 101 of the chassis during the floating process, increase the floating range of the liquid-cooled blind plug connector 2, help ensure that the connection between the liquid-cooled blind plug connector 2 and the fluid connector 504 on the cabinet is more reliable, and help increase the structural strength of the rear window 103 of the cabinet 1 and the cover plate main body 1011.

[0123] In one embodiment, Fig.28 As shown, the liquid supply and return manifold 5 includes a liquid outlet water divider 501 and a liquid inlet water divider 502. The liquid outlet water divider 501 and the liquid inlet water divider 502 respectively include a plurality of branch pipes 503 spaced apart in the vertical direction. There are a plurality of server nodes, which are spaced apart in the vertical direction. The liquid inlet end of the server node can be connected to the branch pipe 503 of the liquid inlet water divider 502, and the liquid outlet end of the server node can be connected to the branch pipe 503 of the liquid outlet water divider 501.

[0124] In one embodiment, a guide rail extending along the plugging direction of the server node and the supply and return liquid manifold 5 is also provided on the side wall of the cabinet. The server node can be inserted into the cabinet along the guide rail and plugged with the supply and return liquid manifold 5 on the cabinet.

[0125] 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 4 and the cabinet signal connector 603 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 602 along the plugging direction is L3; L1>L2>L3.

[0126] Through such an arrangement, when the cabinet of the embodiment of the present invention is connected to the cabinet, the liquid cooling blind plug connector 2 can be first connected with the cabinet fluid connector 504, and then the signal blind plug connector 4 can be connected with the cabinet signal connector 603, and finally, the power supply blind plug connector 3 can be connected with the cabinet power supply connector 602.

[0127] The liquid-cooled blind-plug connector 2 with the highest matching accuracy can complete the connection first, improve the docking accuracy between the chassis and the cabinet, and reduce the error that the liquid-cooled blind-plug connector 2 needs to absorb. Reasonable accuracy level matching requirements can make the three-blind plug structure better adapt to the accuracy requirements of the server node rear window 103 and the cabinet during the installation process, reduce structural deformation, stress concentration and other problems caused by improper installation, and improve the stability and reliability of the system.

[0128] In one embodiment, the cabinet signal connector 603 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 4.

[0129] By such arrangement, during the process of the box body 1 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.

[0130] On this basis, the box body 1 is usually filled with dense electrical connectors and the space is limited. Designing the floating structure at the cabinet end can better utilize 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.

[0131] In one embodiment, the cabinet further includes a first guide pin 604 and a second guide pin 605 .

[0132] The first guide pin 604 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.
