Description

Technical Field

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

[0002] A server cabinet is an installation box for combining and installing panels, plug-ins, chassis, electronic components, devices and mechanical parts and components to form an integral whole.

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

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

[0005] The present application provides a chassis of a server, including:

[0006] A box body, one side of the box body is provided with a cover plate, the cover plate includes a cover plate main body and a sub-cover body. A notch is formed on the side of the cover plate main body close to the rear window of the box body. The sub-cover body is detachably arranged at the notch, and the distance between the sub-cover body and the first wall of the box body is greater than the distance between the cover plate main body and the first wall. The first wall is arranged opposite to the cover plate;

[0007] A liquid cooling blind plug connector, arranged at the rear window of the box body and located between the sub-cover body and the first wall, and capable of floating radially and / or axially along the liquid cooling blind plug connector.

[0008] The present application also provides a liquid cooling system, including:

[0009] A supply and return liquid manifold, the supply and return liquid manifold has a plurality of branch pipes, and fluid connectors are arranged on the branch pipes;

[0010] The liquid cooling blind plug connector of the chassis of the server provided in the first aspect of the present invention is used to be plugged into the fluid connector.

[0011] The present application also provides a cabinet, including:

[0012] A cabinet body, a supply and return liquid manifold is arranged in the cabinet body, the supply and return liquid manifold has a plurality of branch pipes, and fluid connectors are connected to the branch pipes;

[0013] The chassis of the server provided in the first aspect of the present invention is disposed within a cabinet, and the liquid cooling blind plug connector of the chassis is plugged into a fluid connector.

[0014] Through this application, during the plugging process of the chassis of the server in the embodiment of the present invention, the liquid cooling blind plug connector can allow the plug-in member to float along the radial and / or axial directions of the liquid cooling blind plug connector, thereby absorbing the manufacturing tolerances at the cabinet end, enabling the liquid cooling blind plug connector to accurately dock with the fluid connector on the cabinet, and ensuring a reliable connection without liquid leakage between the liquid cooling blind plug connector and the fluid connector on the cabinet.

[0015] Also, since 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 cooling blind plug connector, the sub-cover body can reduce the risk of the liquid cooling blind plug connector colliding with the cover plate of the box body during the floating process, increase the floating range of the liquid cooling blind plug connector, and contribute to ensuring a more reliable connection between the liquid cooling blind plug connector and the fluid connector on the cabinet.

[0016] On this basis, since the area of the sub-cover body itself is small, with the same material and material thickness, the structural strength of the sub-cover body itself can be greater than that of the cover plate main body. The sub-cover body is connected to the box body and the cover plate main body, which helps to increase the structural strength at the rear window of the box body and the cover plate main body.

[0017] Therefore, the chassis of the embodiment of the present invention can reduce the risk of the liquid cooling blind plug connector colliding with the cover plate of the chassis during the floating process, increase the floating range of the liquid cooling blind plug connector, contribute to ensuring a more reliable connection between the liquid cooling blind plug connector and the fluid connector on the cabinet, and help to increase the structural strength at the rear window of the chassis and the cover plate main body.

[0018] 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, that is: it can reduce the risk of the liquid cooling blind plug connector colliding with the cover plate of the chassis during the floating process, increase the floating range of the liquid cooling blind plug connector, contribute to ensuring a more reliable connection between the liquid cooling blind plug connector and the fluid connector on the cabinet, and help to increase the structural strength at the rear window of the chassis and the cover plate main body.

[0019] 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, that is: it can reduce the risk of the liquid cooling blind plug connector colliding with the cover plate of the box body during the floating process, increase the floating range of the liquid cooling blind plug connector, contribute to ensuring a more reliable connection between the liquid cooling blind plug connector and the fluid connector on the cabinet, and help to increase the structural strength at the rear window of the box body and the cover plate main body.

[0077] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0078] The following combines Figures 1 to 28 , to describe the embodiments of the present invention.

[0079] According to an embodiment of the present invention, on the one hand, a chassis of a server is provided, as Figures 1 to 4 shown, including a box body 1 and a liquid cooling blind plug connector 2.

[0080] One side of the box body 1 is provided with a cover plate 101. The cover plate 101 includes a cover plate main body 1011 and a sub-cover body 1013. A notch 1012 is formed on the side of the cover plate main 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 main 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 the axial direction of the liquid-cooled blind plug connector 2.

[0081] During the use of the chassis of the server according to the embodiment of the present invention, during the plugging process, the liquid-cooled blind plug connector 2 can allow the plugging member to float along the radial direction and / or the axial direction of the liquid-cooled blind plug connector 2, so as to absorb the manufacturing tolerance at 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 the reliable connection between the liquid-cooled blind plug connector 2 and the fluid connector 504 on the cabinet without leakage.

[0082] Also, 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, therefore, 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 during the floating process, increase the floating range of the liquid-cooled blind plug connector 2, and help to ensure the more reliable connection between the liquid-cooled blind plug connector 2 and the fluid connector 504 on the cabinet.

[0083] On this basis, since the area of the sub-cover body 1013 itself is small, with 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 box body 1 and the cover plate main body 1011, which helps to increase the structural strength at the rear window 103 of the box body 1 and the cover plate main body 1011.

[0084] Therefore, the chassis according to 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 box body 1 during the floating process, increase the floating range of the liquid-cooled blind plug connector 2, help to ensure the more reliable connection between the liquid-cooled blind plug connector 2 and the fluid connector 504 on the cabinet, and help to increase the structural strength at the rear window 103 of the box body 1 and the cover plate main body 1011.

[0085] 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.

[0086] As a transformable embodiment, in an embodiment not shown in one of the 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.

[0087] As another transformable embodiment, in an embodiment not shown in another drawing, the first wall 102 is a side wall of the box body 1, 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.

[0088] In one embodiment, as Figure 7 and Figure 8 shown, the liquid-cooled blind plug connector 2 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 pipe connection part 2021 and a connection part 2022. The pipe connection part 2021 passes through the adjustment hole 2013, and the connection part 2022 is arranged on the outer periphery of the pipe connection part 2021. The floating adjustment structure 203 passes through the adjustment hole 2013 and the connection part 2022. 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.

[0089] As Figure 9 and Figure 10 shown, since the adapter joint 202 itself includes a pipe connection part 2021 and a connection part 2022, the volume of the adapter joint 202 itself is relatively large. On this basis, the floating adjustment joint is connected to the connection part 2022 on the outer periphery of the pipe connection part 2021, so that the whole adapter joint 202 floats along the radial and / or axial direction of the connection joint, which makes the space required for the adapter joint 202 during the floating process relatively large, and it is necessary to reserve space in the box body 1 for the adapter joint 202 to float. The box body 1 of the server in the embodiment of the present invention can reserve more space in the box body 1 through the sub-cover body 1013, increase the floating range of the liquid-cooled blind plug connector 2, and prevent the liquid-cooled blind plug connector 2 from colliding with the box body 1 during the floating process.

[0090] In one embodiment, as Figure 10 shown, a water-cooled pipe installation bellows is formed on the pipe connection part 2021, which can be used to connect the water-cooled pipe.

[0091] As a transformable embodiment, in an embodiment not shown in one of the drawings, the quick-connect joint 204 directly passes through the adapter joint 202.

[0092] In one embodiment, as Figure 2As described above, an avoidance groove 1031 with an upper opening is formed on the rear window 103 of the box body 1. The liquid-cooled blind plug connector 2 is arranged inside the box body 1 and passes through the avoidance groove 1031. The sub-cover body 1013 includes a cover body main body 10131, a first connecting edge 10132, and a second connecting edge 10134. Among them, the first connecting edge 10132 and the second connecting edge 10134 are connected to the cover body main body 10131. The first connecting edge 10132 is used to abut against the rear window 103 of the box body 1 and is provided with a first connecting portion 10133 capable of connecting with the rear window 103. The second connecting edge 10134 is used to abut against the side wall of the box body 1 and is provided with a second connecting portion 10135 capable of connecting with the side wall of the box body 1.

[0093] In order to ensure good structural strength at the rear window 103 of the box body 1 and avoid deformation of the box body 1 when subjected to external forces, such as improper operations during handling, collision, or installation, which may affect the overall structural integrity of the box body 1. In the related art, the opening for the liquid-cooled blind plug connector 2 to extend out at the rear window 103 of the box body 1 is generally formed in the middle of the rear window 103 and is not connected to the upper end. Otherwise, there is a risk of affecting the structural strength of the rear window 103 of the box body 1 and causing the rear window 103 to be easily deformed.

[0094] This makes it that in the related art, the installation of the liquid-cooled blind plug connector 2 is generally to obliquely insert 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 main board at the bottom of the box body 1. Therefore, a relatively large cut groove needs to be opened on the main board to avoid damage to the main board by the liquid-cooled blind plug connector 2, resulting in a reduction in the area of the main board and affecting the function expansion of the server.

[0095] In the server chassis according to the embodiment of the present application, an avoidance groove 1031 with an upper opening is provided 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 main board of the server caused by oblique insertion installation, so that a relatively large cut groove does not need to be provided on the main board, which helps to increase the area of the main board.

[0096] On this basis, in the embodiment of the present application, as Figure 5 and Figure 6 shown, the cover plate main 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 respectively connected to the rear window 103 of the box body 1 and the side wall of the box body 1. After the sub-cover body 1013 is connected to the box body 1, the first connecting edge 10132 can jointly enclose a closed through hole with the avoidance groove 1031 with an upper opening, and the second connecting edge 10134 can be connected to the side wall of the box body 1, so that the impact received at the rear window 103 can be transmitted to the side wall of the box body 1, thereby enhancing the structural strength at the rear window 103.

[0097] 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.

[0098] 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,

[0099] 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.

[0100] The first fastener and the second fastener preferably include, but are not limited to, bolts or rivets.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] In one embodiment, Figure 5 , Figure 6 , Figure 13 and Figure 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 .

[0105] 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.

[0106] 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.

[0107] 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.

[0108] As a convertible embodiment, in an embodiment not shown in the drawings, the guide protrusion 10136 and the fourth connecting hole 20112 are formed on the upper connecting plate 2011, and the guide hole 20111 and the third connecting hole 10137 are formed on the sub-cover body 1013.

[0109] As a convertible implementation, in another embodiment not shown in the accompanying drawings, the upper connecting plate 2011 is not provided on the liquid-cooled blind plug connector 2, and the guide hole 20111 and the fourth connecting hole 20112 are directly formed on the supporting plate 2014 of the base 201.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] In one embodiment, Figure 11 and Figure 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] Exemplarily, in an optional embodiment, the cumulative tolerance for cabinet manufacturing may be selected to be 2 mm.

[0120] In one embodiment, Figure 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.

[0121] 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 .

[0122] 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.

[0123] 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 .

[0124] 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.

[0125] 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.

[0126] 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 .

[0127] 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.

[0128] 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.

[0129] 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.

[0130] In one embodiment, a friction reducing layer is formed between the connecting rod 20312 and the connecting portion 2022 .

[0131] 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.

[0132] 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 .

[0133] As a variable embodiment, the friction-reducing layer may also be a lubricating oil layer formed between the connecting rod 20312 and the connecting portion 2022 .

[0134] In one embodiment, Figure 13 and Figure 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.

[0135] The connecting base plate 2015 is connected to the bottom wall of the box body 1, which can prevent the liquid-cooled blind plug connector 2 from being arranged at the rear window 103 of the box body 1, so as to avoid deformation or damage of the rear window 103 of the box body 1 during the plugging process of the fluid connector 504 between the box body 1 and the cabinet.

[0136] In one embodiment, the connecting base plate 2015 and the supporting vertical plate 2014 can form an L-shaped base 201, and the connecting base plate 2015 is connected to the side of the supporting vertical plate 2014 away from the adapter joint 202, which can prevent the adapter joint 202 from interfering with the connecting base plate 2015 during the floating process.

[0137] In one embodiment, an avoidance groove 20151 is formed at a position on the connecting base plate 2015 corresponding to the floating bolt 2032.

[0138] The avoidance groove 20151 can provide more floating space for the lower part of the floating bolt 2032 below the floating bolt 2032, prevent the floating bolt 2032 from interfering with the connecting base plate 2015 when the floating bolt 2032 floats downward, can expand the floating range of the liquid-cooled blind plug connector 2 in the vertical direction without increasing the size of the liquid-cooled blind plug connector 2 in the vertical direction, can reduce the weight of the base 201, and helps to reduce the materials required for the base 201.

[0139] The avoidance groove 20151 is preferably but not limited to being formed by removing part of the material on the connecting base plate 2015.

[0140] In one embodiment, arc chamfers are formed at the edges of the supporting vertical plate 2014 and the connecting base plate 2015, which can prevent the floating blind plug connector from scratching the internal electronic devices of the box body 1 during the assembly process.

[0141] In one embodiment, the base 201 further includes a reinforcing rib 2016. The reinforcing rib 2016 is connected between the supporting vertical plate 2014 and the connecting base plate 2015.

[0142] By setting like this, the reinforcing rib 2016 can enhance the connection strength between the connecting base plate 2015 and the connecting side plate 2017, so as not to affect the stiffness of the base 201 itself while increasing the floating range of the liquid-cooled blind plug connector 2.

[0143] Preferably, the reinforcing rib 2016 is arranged in the vertical direction and is located between two adjacent joint through holes 2012. By setting like this, it can prevent the floating bolt 2032 from interfering with the reinforcing rib 2016.

[0144] 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.

[0145] 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 both the bottom wall and the side wall of the box body 1 at the same time, further strengthening the structural strength at the rear window 103 of the box body 1.

[0146] Among them, the connection between the connecting side plate 2017 and the supporting vertical plate 2014 is preferably but not limited to snap connection, riveting or bolt connection.

[0147] In one embodiment, a butt joint groove 104 is formed in the side wall of the box body 1 in a concave shape. The butt joint groove 104 is used to abut against the cover plate 101 of the box body 1. A guiding slope surface 20171 is formed on the upper part of the connecting side plate 2017. From bottom to top, the guiding slope surface 20171 inclines towards the middle position of the box body 1.

[0148] The design of the butt joint groove 104 can increase the connection area between the side wall of the box body 1 and the cover plate 101, make the combination of the two more tight and stable, improve the overall structural strength of the box body 1, and reduce deformation or damage caused by external forces. On this basis, since the butt joint groove 104 is arranged in a concave shape, the gap between the liquid-cooled blind plug connector 2 and the floating module is relatively narrow. The guiding slope surface 20171 can facilitate the liquid-cooled blind plug connector 2 to be slightly inclined when placed into the box body 1 to avoid the butt joint groove 104 and will not cause jamming.

[0149] In one embodiment, the liquid-cooled blind plug connector 2 further includes a guiding sleeve 2025. The guiding sleeve 2025 is arranged on the adapter joint 202. A guiding section is formed on the inner circumference of the guiding sleeve 2025. Along the insertion direction of the liquid-cooled blind plug connector 2, the inner diameter of the guiding sleeve 2025 gradually decreases.

[0150] During the process of the box body 1 being plugged into the cabinet, the guide pin on the cabinet can first contact the guiding sleeve 2025, so that the liquid-cooled blind plug connector 2 on the box body 1 can be accurately docked with the fluid connector 504 on the cabinet, avoiding damage to the liquid-cooled blind plug connector 2. And the guiding sleeve 2025 is arranged on the adapter joint 202 and does not occupy the area of the main board of the server.

[0151] As an alternative implementation manner, in an embodiment not shown in one drawing, the guiding structure between the liquid-cooled blind plug connector 2 and the cabinet can also be selected as the cooperation of a guiding pin and a guiding hole 20111, etc.

[0152] In one embodiment, as Figure 3 and and Figure 4 shown, the box body 1 further includes a liquid outlet 1032 and a fluid collection tank 105. The liquid outlet 1032 is arranged at the rear window 103 of the box body 1. The fluid collection tank 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 collection tank 105.

[0153] With such an arrangement, when there is liquid leakage between the liquid-cooled blind plug connector 2 and the fluid connector 504, the leaked coolant can be discharged through the liquid outlet 1032, the fluid collection tank 105, and the fluid discharge hole 1051 in sequence, preventing the coolant from coming into contact with the electronic devices inside the cabinet 1.

[0154] In a preferred embodiment, the fluid discharge hole 1051 is connected to a water receiving tray for discharging the coolant. A liquid leakage detection line is provided in the water receiving tray, which can give an alarm when detecting liquid leakage in the water receiving tray. Once the coolant leaks, it may cause a short circuit or damage to the server device. By giving an alarm in time, the operation and maintenance personnel can quickly take measures, such as cutting off the power supply, replacing damaged components, etc., thus avoiding further damage to the device. In critical application scenarios such as data centers, the stable operation of the server is crucial. The liquid leakage alarm enables the operation and maintenance personnel to handle the situation before the coolant leakage causes the server to crash, thereby reducing the time and impact of business interruption. Secondly, the coolant leakage may cause an electrical short circuit, which may further lead to safety accidents such as fires. The liquid leakage alarm system can detect the leakage in time and notify the relevant personnel, so as to take measures to prevent the occurrence of accidents.

[0155] In one embodiment, the liquid-cooled blind plug connector 2 includes an inlet connector 2a and an outlet connector 2b, and the inlet connector 2a and the outlet connector 2b are respectively arranged at both ends of the rear window 103 of the cabinet 1.

[0156] With such an arrangement, not only can the forces on both ends of the cabinet 1 be evenly distributed during the blind plugging process, preventing the liquid-cooled blind plug connector 2 from concentrating on one side and causing the force on the side during the insertion of the cabinet 1 into the cabinet, resulting in damage to the liquid-cooled blind plug connector 2 and the fluid connector 504. 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.

[0157] In one embodiment, as Figure 21 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 arranged at the rear window 103 of the cabinet 1 and is located in the middle of the rear window 103. The signal blind plug connector 4 is arranged at the rear window 103 of the cabinet 1. There are two groups of signal blind plug connectors 4, which are respectively arranged on both sides of the power supply blind plug connector 3.

[0158] With the rapid development of artificial intelligence technology, the scale and power density of data centers have been continuously climbing. Liquid-cooled heat dissipation gradually replaces air-cooled heat dissipation due to its advantages such as low noise and low energy consumption, and is more and more widely applied to cabinet products, especially high-density artificial intelligence server cabinet products.

[0159] In the related art, the liquid-cooling blind plug connector 2 of the server cabinet is installed by an operation and maintenance personnel directly connecting the liquid-cooling pipe at the rear window 103 of the cabinet. On the one hand, the liquid-cooling pipeline occupies a large space, resulting in the need to leave an operation space for the operation and maintenance personnel at the rear window 103 of the cabinet, which is likely to affect the density of the server, and the cables to be installed are complicated, resulting in low installation and maintenance efficiency.

[0160] However, the server liquid-cooling blind plug technology faces challenges in the tolerance and guiding problems during the blind plugging process in the actual use. For the liquid, electricity, signal and other three parts of the connection between the server chassis and the cabinet in the embodiments of the present invention, blind plug connection can be adopted, thus getting rid of the numerous pipelines and cables between the traditional cabinet and the chassis, and enabling the server nodes to be easily deployed inside the cabinet.

[0161] On this basis, the power supply blind plug connector 3 is arranged in the middle of the box body 1, which can contribute to the installation force of the server box body 1. The signal blind plug connectors are respectively 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 wiring in the signal connector mounting plate 401.

[0162] In one embodiment, as Figure 24 and Figure 25 shown, the signal blind plug connector 4 includes a connector mounting plate 401 and a signal connector 402.

[0163] Among them, the connector mounting plate 401 is connected to the rear window 103. The signal connector 402 is arranged on the connector mounting plate 401.

[0164] In one embodiment, the signal blind plug connector 4 further includes a guiding block 403. The guiding block 403 is arranged on the connector mounting plate 401, and a guiding through hole 404 is formed in the guiding block 403. Along the plugging direction of the signal blind plug connector 4, the guiding through hole 404 is arranged with an enlarged diameter.

[0165] During the plugging process, the guiding block 403 can cooperate with the wire plug pin on the cabinet, so that the signal blind plug connector 4 can be accurately plugged into the cabinet signal connector 603, and avoid damage to the signal blind plug connector 4 or the cabinet signal connector 603 caused by plugging misalignment.

[0166] In one embodiment, the guiding blocks 403 are arranged in pairs, and at least one guiding block 403 is respectively arranged at both ends of each group of signal connectors 402.

[0167] By setting like this, the guiding blocks 403 can limit the signal connector 402 from both sides of the signal connector 402, thus avoiding the inclination of the server chassis during the plugging process.

[0168] As a transformable embodiment, in an embodiment not shown in one of the drawings, the liquid-cooled blind plug connector 2 is connected to the rear window 103 of the box body 1.

[0169] In one embodiment, as Figure 26 and Figure 27 shown, the power supply blind plug connector 3 further includes a third floating base 301 and a power supply plug 302.

[0170] Among them, the third floating base 301 is provided at the rear window 103 of the box body 1. The power supply plug 302 is provided on the floating base 201 and can float relative to the third floating base 301 in the vertical or horizontal direction.

[0171] By setting it like this, during the process of plugging the box body 1 into the cabinet, the power supply plug 302 can float in the vertical or horizontal direction, so as to absorb the manufacturing tolerances at the cabinet end, so that the power supply blind plug head can be accurately docked with the cabinet power supply plug 302, and the connection is stable and reliable.

[0172] In one embodiment, the third floating base 301 includes a base body. The base body is provided outside the box body 1, and an installation groove is formed on the side facing the box body 1. An installation through hole is formed at the bottom of the installation groove. The power supply plug 302 is provided in the installation groove and passes through the installation through hole. A floating gap 3015 is formed between the power supply plug 302 and the installation through hole in the horizontal and vertical directions.

[0173] In one embodiment, the rear window 103 includes a vertical plate and a top plate connected to the vertical plate. The third floating base 301 further includes a first connecting plate 3011, a first fastener, a second connecting plate 3013 and a second fastener.

[0174] Among them, the first connecting plates 3011 are arranged in pairs and are respectively provided on both sides of the base body in the horizontal direction. Sixth connection holes 3012 are formed on the first connecting plates 3011. The first fastener can pass through the sixth connection holes 3012 and be connected to the vertical plate. The second connecting plate 3013 is connected to the top of the base body. Seventh connection holes 3014 are formed on the second connecting plate 3013. The second fastener can pass through the seventh connection holes 3014 and be connected to the top plate.

[0175] By setting it like this, the third floating module can be connected to both the vertical plate and the top plate of the rear window 103 of the box body 1 at the same time, which helps to strengthen the structural strength of the rear window 103 of the box body 1.

[0176] As a transformable embodiment, in an embodiment not shown in one of the drawings, the third floating module can also be optionally connected to each other by means of clamping, bonding or welding.

[0177] In one embodiment, as Figure 26As shown, the power supply plug 302 has a pair of blades 3021, and a guiding notch 3022 is formed between the pair of blades 3021. Along the insertion direction of the blades 3021, the width of the guiding notch 3022 gradually increases.

[0178] By such an arrangement, during the process of the cabinet 1 being inserted into the cabinet, the guiding notch 3022 can cooperate with the power supply connector of the cabinet 1, thereby guiding the blades 3021 of the power supply plug 302 to be accurately inserted into the power supply connector of the cabinet 1.

[0179] According to an embodiment of the present invention, on the other hand, a liquid cooling system is further provided, which includes a supply and return liquid manifold 5 and a chassis. A fluid connector 504 is connected to a branch pipe 503 of the supply and return liquid manifold 5. The chassis is the 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 inserted into the fluid connector 504.

[0180] The liquid cooling system transports the cooled coolant to the supply and return liquid manifold 5 through a cold quantity distribution module, and then 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 device 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 cold quantity distribution module for re-cooling and circulation.

[0181] The liquid cooling system is widely used in places that require efficient heat dissipation such as data centers and server rooms. With the development of technologies such as cloud computing, big data, and artificial intelligence, the power density of data centers has been continuously climbing, and traditional air cooling technologies are difficult to meet the heat dissipation requirements of high-power components. The liquid cooling technology, with its efficient heat dissipation ability, has become an effective means to reduce the energy utilization efficiency of data centers. As one of the core components of the liquid cooling system, the liquid cooling system is crucial for ensuring the normal operation and heat dissipation effect of the liquid cooling system.

[0182] 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, that is: it can reduce the risk of the liquid cooling blind plug connector 2 colliding with the cover plate 101 of the cabinet 1 during the floating process, increase the floating range of the liquid cooling blind plug connector 2, contribute to ensuring a more reliable connection between the liquid cooling blind plug connector 2 and the fluid connector 504 on the cabinet, and contribute to increasing the structural strength at the rear window 103 of the cabinet 1 and the cover plate main body 1011.

[0183] According to an embodiment of the present invention, on the other hand, a cabinet is further provided, which includes a cabinet body and a chassis. Among them, a supply and return liquid 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 supply and return liquid manifold 5. The chassis is the chassis of the server provided in the first aspect of the present invention, and is arranged in the cabinet body, and the liquid cooling blind plug connector 2 of the server node is inserted into the fluid connector 504.

[0184] The cabinet according to the third aspect of the present invention includes or uses the chassis according to the first aspect of the present invention, and thus has its beneficial effects, that is: it can reduce the risk of collision between the liquid-cooled blind plug connector 2 and 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 a more reliable connection between the liquid-cooled blind plug connector 2 and the fluid connector 504 on the cabinet, and help increase the structural strength at the rear window 103 of the box body 1 and the cover plate main body 1011.

[0185] In one embodiment, as Figure 28 shown, the supply and return liquid manifold 5 includes a liquid outlet distributor 501 and a liquid inlet distributor 502. The liquid outlet distributor 501 and the liquid inlet distributor 502 respectively include a plurality of branch pipes 503 arranged at intervals in the vertical direction. There are a plurality of server nodes, which are arranged at intervals in the vertical direction. The liquid inlet end of the server node can communicate with the branch pipe 503 of the liquid inlet distributor 502, and the liquid outlet end of the server node can communicate with the branch pipe 503 of the liquid outlet distributor 501.
