[0053] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0054] Reference below Figures 1-9 A server chassis 100 according to an embodiment of the present application is described.

[0055] like Figures 1-9 As shown, the server chassis 100 according to an embodiment of the present application includes: a chassis 10, a switching module 20, a CPU module 30, a GPU module 40, a bridge module 60 and a liquid cooling pipe module 80.

[0056] Specifically, the box body 10 is arranged in the front-to-back direction (eg Figure 1 The front and rear directions shown in the figure) extend, the box 10 has a cavity; the exchange module 20 is plate-shaped and arranged horizontally, the number of exchange modules 20 is multiple, and the multiple exchange modules 20 are arranged in the up and down directions (such as Figure 1 The CPU module 30 is a plate-shaped member and is arranged horizontally. There are multiple CPU modules 30, and multiple CPU modules 30 are stacked in the vertical direction. The GPU module 40 is a plate-shaped member and is arranged vertically. There are multiple GPU modules 40, and multiple GPU modules 40 are stacked in the left and right direction (as shown). Figure 1The bridging module 60 is provided in the cavity and divides the cavity into a front cavity 101 and a rear cavity 102 arranged in the front-to-back direction. The switching module 20, the CPU module 30 and the GPU module 40 are all provided in the front cavity 101 and arranged in sequence from top to bottom. The bridging module 60 is configured for communication connection between the switching module 20, the CPU module 30 and the GPU module 40. The liquid cooling pipe module 80 is provided in the rear cavity 102, wherein, in the front-to-back direction, the rear ends of the switching module 20 and the CPU module 30 are provided with a first liquid cooling joint, and the rear end of the GPU module 40 is provided with a second liquid cooling joint 46. The liquid cooling pipe module 80 is connected to multiple first liquid cooling joints and multiple second liquid cooling joints 46.

[0057] In this embodiment, the server chassis 100 is provided with a switching module 20, a CPU module 30 and a GPU module 40. The switching module 20 can be used to interact with external devices or other server chassis 100 for network data. The CPU module 30 can be used for data calculation and processing and controlling the operation of the server. The GPU module 40 can be used to accelerate large-scale parallel computing such as scientific computing and deep learning to meet the operational needs of the server chassis 100.

[0058] In this embodiment, multiple switching modules 20, CPU modules 30 and GPU modules 40 are provided to meet the operation and use requirements of the server. For example, when the server chassis 100 in this embodiment is a 12U server chassis 100, the total height of the multiple switching modules 20, CPU modules 30 and GPU modules 40 in this embodiment can be 12U. During the actual use of the server chassis 100, the number of switching modules 20, CPU modules 30 and GPU modules 40 actually arranged in the server chassis 100 can also be reduced as needed to meet different operation and use requirements, reduce operating costs to a certain extent, and make the operation of the server chassis 100 more economical.

[0059] It is understandable that when the server chassis 100 uses liquid cooling to dissipate heat for the switch module 20, the CPU module 30, and the GPU module 40, pipes for transporting coolant need to be arranged. In the related art, the pipes for transporting coolant are arranged in the upper and lower directions with multiple switch modules 20, multiple CPU modules 30, and multiple GPU modules 40, so that the CPU module 30, the GPU module 40, and the switch module 20 are arranged relatively loosely and a certain gap needs to be left between the pipes, so that the overall structure occupies a larger space in the upper and lower directions, and the overall height of the server chassis 100 is higher. In addition, water and electricity are not well separated, which makes it easy for the server chassis 100 to short-circuit or even damage the hardware due to pipe leakage during operation, resulting in poor operational stability and reliability of the server chassis 100.

[0060] In this embodiment, the server chassis 100 is provided with a box body 10, the box body 10 has a cavity, the bridge module 60 is arranged in the cavity and divides the cavity into a front cavity 101 and a rear cavity 102, wherein the front cavity 101 is arranged with a switch module 20, a CPU module 30 and a GPU module 40, and the rear cavity 102 is arranged with a liquid cooling pipe module 80. The arrangement is reasonable, so that the liquid cooling pipe module 80 for cooling liquid delivery can be arranged in a front-to-back separation with the switch module 20, the CPU module 30 and the GPU module 40, thereby well avoiding the liquid cooling pipe module 80 from crossing. The switch module 20, GPU module 40 and CPU module 30 interfere with each other when they are arranged and assembled in the box 10, so that the switch module 20, GPU module 40 and CPU module 30 can be arranged more compactly. The liquid cooling pipe module 80 does not occupy the total height of the server chassis 100, so that the switch module 20, GPU module 40 and CPU module 30 are arranged more compactly in the up and down directions, thereby making the overall height of the server chassis 100 lower and the server chassis 100 occupying less space, which can effectively alleviate the space pressure of the computer room.

[0061] In this embodiment, the switching module 20 is configured to be plate-shaped and arranged horizontally, and multiple switching modules 20 are stacked in the vertical direction. The CPU module 30 is configured to be plate-shaped and arranged horizontally, and multiple CPU modules 30 are stacked in the vertical direction. The GPU module 40 is configured to be plate-shaped and arranged vertically, and multiple GPU modules 40 are stacked in the left and right direction. The reasonable layout facilitates the interaction between the server chassis 100 and external devices and the operation of operation and maintenance personnel, and can fully utilize the layout space of the front cavity 101, so that multiple switching modules 20, multiple CPU modules 30 and multiple GPU modules 40 can be compactly arranged in the front cavity 101.

[0062] In this embodiment, the bridge module 60 divides the cavity into a front cavity 101 and a rear cavity 102 arranged front and back. The switch module 20, the CPU module 30, and the GPU module 40 are all arranged in the front cavity 101, which can facilitate later maintenance and meet the interaction needs of the server chassis 100 and external devices. The bridge module 60 is used to connect the switch module 20, the CPU module 30, and the GPU module 40 to achieve communication connection, which can well reduce the layout of cables, making the assembly of the server chassis 100 more convenient and making the space occupied by cables less. Since the switch module 20, the CPU module 30, and the GPU module 40 are stacked and arranged up and down, the server chassis 100 can be connected to the bridge module 60. , making the wiring in the bridge module 60 more convenient and the cable length shorter, so that the overall structure of the bridge module 60 can be arranged more compactly in the cavity and occupy less space, thereby making the overall structure of the server chassis 100 more compact and the overall space occupied smaller. At the same time, the switching module 20, the CPU module 30 and the GPU module 40 are communicated and connected in the front and back directions through the bridge module 60, which can well avoid the space occupied by the cable connection arrangement in the up and down directions, thereby making the switching module 20, the CPU module 30 and the GPU module 40 more compact when arranged in the up and down directions, so that the overall height of the server chassis 100 can be lower.

[0063] In this embodiment, the switching module 20, the CPU module 30 and the GPU module 40 are arranged in the front cavity 101, and the bridge module 60 is arranged on the rear side of the switching module 20, the CPU module 30 and the GPU module 40 and is used to uniformly communicate and connect the switching module 20, the CPU module 30 and the GPU module 40. The liquid cooling pipe module 80 is arranged in the rear cavity 102, so that a good area separation can be formed in the server chassis 100, so that the server chassis 100 can be modularly assembled during assembly, which is more convenient to assemble and maintain, and can be more orderly when making electrical connections and arranging liquid cooling pipes. The liquid cooling pipe module 80 is arranged in the rear cavity 102, which can effectively avoid the switching module 20, the CPU module 30 and the GPU module 40 from short-circuiting or even hardware damage due to liquid leakage during assembly with the CPU module 30, the switching module 20 and the GPU module 40, thereby improving the operation stability and reliability of the server chassis 100.

[0064] In this embodiment, the rear ends of the switching module 20 and the CPU module 30 are each provided with a first liquid cooling joint, and the rear end of the GPU module 40 is provided with a second liquid cooling joint 46. The reasonable arrangement allows the liquid cooling pipe module 80 to conveniently transport cooling liquid to each switching module 20, CPU module 30, and GPU module 40 through the first liquid cooling joint and the second liquid cooling joint 46 for heat dissipation.

[0065] According to the server chassis 100 of the embodiment of the present application, a bridge module 60 is provided, the bridge module 60 is provided in the cavity of the case 10 and divides the cavity into a front cavity 101 and a rear cavity 102 arranged front and back, a plurality of switch modules 20, a plurality of CPU modules 30 and a plurality of GPU modules 40 are stacked and arranged in the front cavity 101 in the up and down directions, the switch module 20, the CPU module 30 and the GPU module 40 are communicatively connected through the bridge module 60 on the rear side, the liquid cooling pipe module 80 is provided in the rear cavity 102 and transports the cooling liquid through the first liquid cooling joint at the rear end of the switch module 20 and the CPU module 30 and the second liquid cooling joint 46 at the rear end of the GPU module 40 for liquid cooling operation, and the arrangement is compact, so that the switch module 20, the CPU module 30 and the GPU module 40 can be modularly assembled, and the assembly Maintenance is more convenient. The liquid cooling pipe module 80 and the bridge module 60 are arranged in front and behind the switching module 20, the CPU module 30 and the GPU module 40, which can effectively avoid the space occupied by the cables in the liquid cooling pipe module 80 and the bridge module 60 in the height direction of the box 10, so that the switching module 20, the CPU module 30 and the GPU module 40 are arranged more compactly in the up and down directions, so that the height of the box 10 can be reduced, thereby making the overall height of the server chassis 100 lower, and effectively alleviating the space pressure of the computer room when the server chassis 100 is arranged in the computer room, and can make the liquid cooling pipe module 80 and the switching module 20, the CPU module 30 and the GPU module 40 be well separated, thereby reducing the probability of short circuit or hardware failure due to pipeline leakage, so that the server chassis 100 can operate more stably and reliably.

[0066] In a possible implementation of this application, reference Figure 1 、 Figure 3 、 Figure 4 and Figure 7 As shown, the switching module 20 and the CPU module 30 can be provided with a first electrical connector at the rear end in the front-to-back direction. The server chassis 100 can also include a power connection module 70, which is arranged in the rear cavity 102. The power connection module 70 includes an adapter 73, and the adapter 73 is provided with a first connection part. The first connection part extends in the up-down direction, and multiple first electrical connectors are plugged and connected to the first connection part in the front-to-back direction, wherein the first electrical connector is provided on one side of the switching module 20 and the CPU module 30 in the left-to-right direction, and the first liquid cooling joint is provided on the other side of the switching module 20 and the CPU module 30 in the left-to-right direction.

[0067] In this embodiment, the rear ends of the switching modules 20 and the CPU modules 30 are each provided with a first electrical connector, which is connected to the adapter 73 of the power connection module 70. The structure is simple, and the power connection module 70 can supply power to each switching module 20 and the CPU module 30 via an external power supply, thereby meeting the operating requirements of the switching modules 20 and the CPU modules 30.

[0068] The first electrical connector and the first connection portion of the adapter 73 are plug-in connected in the front-to-back direction, which facilitates the power connection of the switching module 20 and the CPU module 30 in the case 10. For example, when the switching module 20 is put into the case, the assembler can load the switching module 20 from the front end of the case 10 into the front cavity 101 and move it backward. The first electrical connector can form a plug-in connection with the first connection portion of the adapter 73 as the switching module 20 moves. After the switching module 20 is moved into place, the switching module 20 is connected to the adapter 73. When the switching module 20 needs to be taken out for maintenance, the switching module 20 can be moved forward in the front-to-back direction to separate the first electrical connector from the first connection portion. As a result, the switching module 20 and the CPU module 30 can be easily taken in and out during assembly and maintenance, thereby making the server chassis 100 more convenient to assemble and maintain.

[0069] Specifically, a support plate for supporting each switching module 20 and CPU module 30 can be provided in the front cavity 101 to meet the installation and layout requirements of the switching module 20 and the CPU module 30 in the front cavity 101. The switching module 20 and the CPU module 30 can be conveniently loaded into or removed from the front cavity 101 along the support plate. The specific structure and layout of the support plate can be reasonably set as needed and are not specifically limited here.

[0070] In this embodiment, the power connection module 70 is provided with an adapter 73 that is plugged into and connected to the multiple first electrical connectors. This not only allows the switch module 20 and the CPU module 30 to be conveniently connected to the power connection module 70, but also reduces the number of cables used, thereby greatly reducing the difficulty and complexity of wiring in the rear cavity 102, making the power connection module 70 occupy less space, and thus making the overall structural layout in the box body 10 more compact, which can, to a certain extent, make the server chassis 100 occupy even less space.

[0071] In this embodiment, the power connection module 70 is provided with an adapter 73 connected to multiple first electrical connectors, which can make the arrangement of the adapter 73 and the liquid cooling tube module 80 in the rear cavity 102 more convenient, so that the liquid cooling tube module 80 and the adapter 73 can form a larger interval when arranged, avoiding the staggered arrangement of cables and pipes, so that the pipe arrangement and wiring in the rear cavity 102 can be more orderly, and the cables and pipes can be well spatially separated, thereby reducing the probability of liquid leaking from the pipe and falling on the cable, and further reducing the probability of short circuit or hardware failure due to leakage during the operation of the server chassis 100, so that the server chassis 100 can operate more stably and reliably.

[0072] In this embodiment, the first electrical connector is provided on one side of the switch module 20 and the CPU module 30 in the left-right direction, and the first wild wolf connector is provided on the other side of the switch module 20 and the CPU module 30 in the left-right direction. That is to say, the rear end of the switch module 20 is provided with a first electrical connector and a first liquid-cooling connector on both sides of the left-right direction, and the rear end of the CPU module 30 is provided with a first electrical connector and a first liquid-cooling connector on both sides of the left-right direction. The first electrical connectors on multiple switch modules 20 and the first electrical connectors on multiple CPU modules 30 are located on the same side, and the first liquid-cooling connectors on multiple switch modules 20 and the first liquid-cooling connectors on multiple CPU modules 30 are located on the same side. In this way, multiple first electrical connectors and multiple first liquid-cooling connectors can be evenly connected. Arranged together, the first adapter portion of the adapter 73 only needs to be arranged on one side of the switching module 20 in the left-right direction to achieve plug-in connection with multiple first electrical connectors on the switching module 20 and the CPU module 30, and the liquid cooling tube module 80 only needs to arrange the pipe joint structure on the other side of the switching module 20 in the left-right direction to achieve pipeline connection with multiple first liquid cooling joints on the switching module 20 and the CPU module 30, so that multiple switching modules 20 and multiple CPU modules 30 can be conveniently connected to the power connection module 70 and the liquid cooling tube module 80, which greatly reduces the layout length of the adapter 73 and the layout length of the pipeline in the liquid cooling tube module 80, so that the overall structure of the power connection module 70 and the liquid cooling tube module 80 can be more compact and occupy less space.

[0073] In this embodiment, the multiple first electrical connectors and the multiple first liquid cooling joints are spaced far apart in the left and right directions, so that the first connection portion of the adapter 73 and the pipeline structure in the liquid cooling tube module 80 can be effectively separated in the left and right directions, thereby achieving a good effect of separating water and electricity, thereby effectively reducing the probability of circuit breakage and hardware failure caused by leakage of the liquid cooling tube module 80 or leakage at the first liquid cooling joint, thereby improving the stability and reliability of the server chassis 100 during operation.

[0074] In a possible implementation of this application, reference Figure 3 、 Figure 4 and Figure 8 As shown, the GPU module 40 can be provided with a second electrical connector 47 at the rear end in the front-to-back direction, and the adapter 73 can also be provided with a second connecting portion, which is horizontally arranged and extends in the left-right direction. Multiple second electrical connectors 47 are plug-connected with the second connecting portion in the front-to-back direction, wherein the second electrical connector 47 is provided on the upper side of the second liquid cooling joint 46.

[0075] In this embodiment, a second electrical connector 47 is provided at the rear end of the GPU module 40, and the second electrical connector 47 is plug-connected to the second connection portion of the adapter 73 in a front-to-back manner. Since multiple GPU modules 40 are stacked and arranged in the left-right direction, multiple second electrical connectors 47 are arranged in the left-to-right direction. The second connection portion is arranged horizontally and extends in the left-to-right direction, which can meet the plug-in connection needs with multiple second electrical connectors 47, and has a smaller size in the up and down direction, which is convenient for arrangement. For example, the second connection portion can be arranged at the bottom of the bridge module 60 to facilitate connection with the second electrical connector 47.

[0076] The second electrical connector 47 is plugged into the second connection portion of the adapter 73 in the front-to-back direction, which facilitates the power connection of the GPU module 40 in the case 10. For example, when the GPU module 40 is put into the case, the assembler can load the switching module 20 from the front end of the case 10 into the front cavity 101 and move it backward. The second electrical connector 47 can form a plug-in connection with the second connection portion of the adapter 73 as the GPU module 40 moves. After the GPU module 40 moves into place, the GPU module 40 is connected to the adapter 73. When the GPU module 40 needs to be taken out for maintenance, the switching module 20 can move forward in the front-to-back direction to separate the second electrical connector 47 from the second connection portion. As a result, the GPU module 40 can be easily taken in and out during assembly and maintenance, making the server case 100 more convenient to assemble and maintain.

[0077] Specifically, a partition plate for separating multiple GPU modules 40 can be provided in the front cavity 101 to meet the installation and layout requirements of the GPU module 40 in the front cavity 101. The switching module 20 and the CPU module 30 can be conveniently loaded into or removed from the front cavity 101 in the front-to-back direction under the support and guidance of the partition plate. The specific structure and layout of the partition plate can be reasonably set as needed and are not specifically limited here.

[0078] In this embodiment, the second electrical connector 47 is arranged on the upper side of the second liquid-cooling joint 46, so that after the GPU module 40 is assembled with the power connection module 70 and the liquid-cooling pipe module 80, the second connection portion of the adapter 73 can be located above the multiple second liquid-cooling joints 46, thereby effectively preventing leakage of the second liquid-cooling joints 46 from falling onto the adapter 73, thereby further reducing the probability of short circuit or hardware failure, and allowing the server chassis 100 to operate more stably and reliably.

[0079] The multiple first liquid-cooling joints in this embodiment are arranged in the up-down direction and are located on the same side of the exchange module 20 and the CPU module 30 in the left-right direction, so that the first liquid-cooling joint and the pipe and pipe joint structure connecting the first liquid-cooling joint in the liquid-cooling tube module 80 only need to be arranged on one side of the rear cavity 102 in the left-right direction, thereby greatly reducing the leakage range in the rear cavity 102 when the first liquid-cooling joint or the pipe in the liquid-cooling tube module 80 leaks, and greatly reducing the probability of the leaked liquid falling onto the adapter 73 below. For example, the adapter 73 can be staggered with the first liquid-cooling joint and the liquid-cooling tube module 80 in the up-down direction, or the adapter 73 can be separated from the first liquid-cooling joint and the pipe joint structure of the liquid-cooling tube module 80 in the up-down direction by the bridging module 60 to play a shielding role.

[0080] In a possible implementation of this application, reference Figure 4 and Figure 5 As shown, the adapter 73 may include: a mainboard segment 731 and a support plate segment 733. The mainboard segment 731 is arranged horizontally and is provided between the bridge module 60 and the bottom wall of the cavity. The mainboard segment 731 forms a second connection portion. In the front-to-back direction, the edge portion of the side of the mainboard segment 731 that faces away from the GPU module 40 is folded upward to form a first folded edge 732. The power connection module 70 also includes a power board 71 and a power supply unit 72. The power board 71 is connected to the power supply unit 72, and the first folded edge 732 is plugged into the power board 71. The support plate segment 733 extends in the up-down direction and is connected to the mainboard segment 731. The support plate segment 733 forms a first connection portion.

[0081] In this embodiment, the adapter 73 includes a mainboard segment 731, which is arranged horizontally and disposed between the bridging module 60 and the bottom wall of the cavity. The mainboard segment 731 forms a second connecting portion, has a simple structure, and a reasonable arrangement. The bridging module 60 can provide a certain shielding effect for the mainboard segment 731, preventing liquid leakage at the first liquid cooling joint from falling onto the mainboard segment 731.

[0082] In this embodiment, the edge portion of the mainboard section 731 facing away from the GPU module 40 is folded upward to form a first folded edge 732. Specifically, the first folded edge 732 can be spaced apart from the first liquid cooling connector in the left-right direction. The first folded edge 732 is connected to the power board 71 of the power connection module 70. For example, the first folded edge 732 can be provided with multiple electrical connection posts, and the power board 71 has a socket. The first fold is electrically connected to the power board 71 by plugging the electrical connection posts into the socket. The power board 71 can extend in the left-right direction to match the first folded edge 732. The power board 71 is connected to the power supply unit 72, so that the server chassis 100 can receive external power through the power supply unit 72 and, after conversion, supply power to the switch module 20, the CPU module 30, and the GPU module 40 through the power board 71 and the adapter 73 to meet the operating needs of the server chassis 100.

[0083] The adapter 73 includes a support plate section 733 that extends vertically and connects to the main plate section 731. This section forms the first connection portion, offering a simple structure that effectively connects multiple first electrical connectors. Alternatively, the adapter 73 may be a copper busbar, and the first and second electrical connectors 47 may be power clamps for connecting the busbars. A reinforcement structure may be provided at the junction of the support plate section 733 and the main plate section 731 to enhance the stability and reliability of the connection between the two.

[0084] In a possible implementation of this application, reference Figure 3 、 Figure 4 and Figure 7 As shown, the bridge module 60 may include: a first connector 63 and a second connector 64, the switching module 20 and the CPU module 30 are both provided with a first connection terminal at the rear end in the front-to-back direction, a plurality of first connection terminals are plug-connected to the first connector 63, and the first connection terminals and the first liquid cooling joint are arranged at intervals in the left-to-right direction; the second connector 64 is connected to the first connector 63 through a cable, and the GPU module 40 is provided with a second connection terminal 48 at the rear end in the front-to-back direction, the second connection terminal 48 is plug-connected to the second connector 64, and the second connection terminal 48 is located on the upper side of the second liquid cooling joint 46.

[0085] In this embodiment, the bridge module 60 is provided with a first connector 63 and a second connector 64. The first connector 63 is plugged into the first connection terminal at the rear end of the switching module 20 and the CPU module 30, and the second connector 64 is plugged into the second connection terminal 48 at the rear end of the GPU module 40. The first connector 63 and the second connector 64 are connected by a cable, so that the switching module 20, the CPU module 30 and the GPU module 40 can complete the communication connection during the process of being assembled into the front cavity 101 along the front-to-back direction and moved into place. Any one of the switching module 20, the CPU module 30 and the GPU module 40 can be disconnected by moving away from the bridge module 60 along the front-to-back direction for separate replacement or maintenance, so that the server chassis 100 can be modularly assembled and maintained during the assembly and subsequent maintenance process, making the operation and maintenance of the server chassis 100 more convenient.

[0086] For example, when one of the switch modules 20 is removed for maintenance, the switch module 20 moves forward, separating the first connection terminal of the switch module 20 from the first connector 63, the first electrical connector from the adapter 73, and the first liquid-cooling joint from the liquid-cooling tube module 80, thereby allowing the switch module 20 to be removed smoothly. When the switch module 20 is assembled into the chassis 10, the switch module 20 moves backward, driving the first connection terminal to be inserted into the first connector 63, the first electrical connector to be plugged into the adapter 73, and the first liquid-cooling joint to be plugged into the pipe joint of the liquid-cooling tube module 80, thereby completing the installation. Specifically, the piping structure in the switch module 20, the CPU module 30, and the GPU module 40, as well as the pipe joint structure of the liquid-cooling tube module 80, can be provided with a closing device, so that the piping can be automatically closed when the first liquid-cooling joint or the second liquid-cooling joint 46 is separated from the liquid-cooling tube module 80, and the piping can be automatically opened when the first liquid-cooling joint or the second liquid-cooling joint is connected to the liquid-cooling tube module 80.

[0087] In this embodiment, the first connection terminals and the first liquid-cooling connector are spaced apart in the left-right direction, and the second connection terminals are located above the second liquid-cooling connector 46. This rational arrangement effectively separates water and electricity, ensuring more stable and reliable server operation. Optionally, the first connector 63 and the second connector 64 can both be high-density male connectors, and the first connection terminals and the second connection terminals 48 can be high-density female connectors. The cable connecting the first connector 63 and the second connector 64 is arranged on the side of the bridge module 60 facing the rear cavity 102, that is, arranged within the rear cavity 102. This rational arrangement effectively meets the layout requirements of the bridge module 60, the switch module 20, etc.

[0088] In a possible implementation of this application, reference Figure 3 and Figure 4 As shown, the bridging module 60 may further include: a main frame 61 and a partition 62, the main frame 61 being connected to the inner wall of the cavity, the first connector 63 and the second connector 64 being both provided on the main frame 61; the partition 62 being provided at the lower end of the main frame 61 and being connected to the main frame 61, the partition 62 extending along the front-to-back direction and being located on the side of the main frame 61 facing the rear cavity 102, a plurality of partitions 62 being arranged at intervals along the left-to-right direction, and in the left-to-right direction, connecting grooves are formed between the partitions 62 and the side walls of adjacent cavities or between adjacent partitions 62, and the connecting grooves and the second connector 64 are arranged relative to each other in the front-to-back direction.

[0089] In this embodiment, the bridge module 60 includes a main frame 61, which is connected to the inner wall of the cavity. For example, the main frame 61 and the inner wall of the cavity can be connected by a snap connection, a fastening connection, or a position-limiting fit, etc., so as to meet the installation and fixation requirements of the main frame 61. The first connector 63 and the second connector 64 are both disposed on the main frame 61, which has a simple structure. The main frame 61 can provide a mounting location for the first connector 63 and the second connector 64, making the arrangement of the first connector 63 and the second connector 64 more convenient.

[0090] In this embodiment, a plurality of partitions 62 are provided at the lower end of the main frame 61. The partitions 62 are arranged at intervals along the left and right directions and cooperate with the side walls of the cavity to define a plurality of connection grooves. The connection grooves and the second connector 64 are arranged relative to each other in the front-to-back direction. For example, the plurality of connection grooves and the plurality of second connectors 64 can be arranged in a one-to-one correspondence, so that when the first connector 63 and the second connector 64 are connected by cables, the partitions 62 can guide, position and separate the cable connections, so that the cables can be quickly connected, thereby making the assembly of the server chassis 100 more convenient and efficient, and greatly improving the overall structural strength of the main frame 61 and the plurality of partitions 62, so that the main frame 61 and the partitions 62 can cooperate to more stably support the first connector 63, the second connector 64 and the cables, thereby making the connection and assembly of the switch module 20, the CPU module 30, the GPU module 40 with the bridge module 60, the liquid cooling pipe module 80 and the power connection module 70 more stable and reliable.

[0091] In a possible implementation of this application, reference Figure 3 and Figure 4 As shown, the partition 62 can be provided with an air-cooling channel 621, which passes through the partition 62 and the main frame 61 in the front-to-back direction. There are multiple air-cooling channels 621, and the multiple air-cooling channels 621 are arranged at intervals in the up-down direction.

[0092] In this embodiment, the partition 62 is provided with an air-cooling channel 621, and the air-cooling channel 621 passes through the partition 62 and the main frame 61 in the front-to-back direction. For example, the partition 62 and the main frame 61 can be an integral part, and multiple air-cooling channels 621 are arranged at intervals in the up-down direction. The structure is simple, so that when the server chassis 100 is subjected to air cooling and heat dissipation, the front air intake flows through the switching module 20, the CPU module 30 and the various electrical components in the GPU module 40 for air cooling and heat dissipation, and the air flow then flows from the front cavity 101 through the bridge module 60 into the rear cavity 102. When the air flow flows through the bridge module 60, the air flow can pass through the air-cooling channel 621 through the bridge module 60 and from the front cavity 101 flows smoothly into the rear cavity 102, avoiding the obstruction of air flow by the large number of cables at the bridge module 60, thereby making the air flow poor. Therefore, when the server chassis 100 is running, the electrical components that are not liquid-cooled in the switch module 20, CPU module 30 and GPU module 40 in the front cavity 101 can all obtain effective air-cooling and heat dissipation, so that the cables, power board 71 and other structures in the rear cavity 102 can obtain effective air-cooling and heat dissipation, thereby making the heat dissipation performance of the server chassis 100 better, and making the server chassis 100 obtain better heat dissipation effect through the combination of liquid cooling and air cooling during operation, thereby making the heat dissipation performance of the server chassis 100 better.

[0093] In a possible implementation of this application, reference Figure 1 As shown, the server chassis 100 can also include a rear plug-in box module 90 and a fan. The rear plug-in box module 90 is arranged in the rear cavity 102 and is located at the rear end of the box body 10. The rear plug-in box module 90 is provided with a plurality of mounting slots. The mounting slots pass through the rear plug-in box module 90 along the front-to-back direction and are connected to the rear cavity 102. The fan is arranged in the mounting slot, and the plurality of fans are arranged in a one-to-one correspondence with the plurality of mounting slots.

[0094] In this embodiment, a rear plug-in box module 90 and a fan are provided, and multiple fans are installed in the installation slots. The rear plug-in box module 90 cooperates with the fan to close the rear end of the box body 10, so that components such as the power board 71 in the rear cavity 102 can be in a more stable operating environment, and the rear plug-in box module 90 can provide a good installation and layout position for components such as the liquid cooling pipe module 80, the power board 71 and the fan. For example, the external pipe joint structure of the liquid cooling pipe module 80 can be fixed on the rear plug-in box module 90 to be connected to the external liquid cooling equipment.

[0095] In this embodiment, multiple fans are arranged on the rear plug-in box module 90. When the multiple fans are in operation, they can drive the airflow to flow more stably from the front cavity 101 to the rear cavity 102 and out of the box body 10, so that the air cooling and heat dissipation effect of each component in the rear cavity 102 is better improved.

The multiple mounting holes 611 are arranged one-to-one correspondingly to the multiple first liquid-cooling joints. The liquid-cooling tube module 80 includes a first current collecting part 81, and the first current collecting part 81 is provided with multiple pipe joints.

The liquid inlet pipe is connected to the first joint, and the liquid return pipe is connected to the second joint to meet the transportation needs of the cooling liquid.

[0098] In this embodiment, a mounting hole 611 is provided on the main frame 61, which can facilitate the pipe joint to pass through the bridge module 60 and be connected to the first liquid cooling joint. The mounting hole 611 can play a certain fixing role on the pipe joint, so that the first collecting member 81 can be stably fixed on the main frame 61, thereby enabling the liquid cooling pipe module 80 to be stably connected to the exchange module 20 and the CPU module 30.

[0099] In a possible implementation of this application, reference Figure 3 and Figure 4 As shown, the liquid-cooling tube module 80 may further include a second current collecting member 82, which may be disposed below the main frame 61 and the adapter 73. The second current collecting member 82 is provided with a plurality of pipe joints that are plugged into and connected to the plurality of second liquid-cooling joints 46. The arrangement of the second current collecting member 82 below the adapter 73 can well match the arrangement of the second liquid-cooling joints 46, so that the liquid-cooling tube module 80 can be conveniently connected to the plurality of second liquid-cooling joints 46 through the second current collecting member 82. For example, the second liquid-cooling joints 46 may include a liquid inlet joint and a liquid outlet joint, and the pipe joints of the second current collecting member 82 may include a first joint and a second joint, wherein the liquid inlet pipe is connected to the first joint, and the liquid return pipe is connected to the second joint, so as to meet the needs of conveying the cooling liquid.

[0100] In a possible implementation of this application, reference Figure 1 and Figure 3 As shown, the bridging module 60 may further include a handheld frame 65, which is connected to the main frame 61 and is located on the side of the main frame 61 facing the rear cavity 102 in the front-to-back direction. The box body 10 may include: a main box body 11 and an inspection panel 12, the main box body 11 forms a cavity, and the upper end of the main box body 11 is provided with an inspection port connected to the cavity, and the inspection port faces the bridging module 60 and the rear cavity 102; the inspection panel 12 covers the inspection port.

[0101] In this embodiment, the bridge module 60 is provided with a handheld frame 65, which is connected to the main frame 61 and is located on the side of the main frame 61 facing the rear cavity 102 in the front-to-back direction, that is, the handheld frame 65 is arranged in the rear cavity 102, and the box body 10 includes a main box body 11 and an inspection panel 12. The upper end of the main box body 11 is provided with an inspection port connected to the cavity, and the inspection port faces the bridge module 60 and the rear cavity 102. The inspection port cover is provided with an inspection panel 12. When the server chassis 100 needs to inspect and maintain the bridge module 60, after the inspection panel 12 is opened, the bridge module 60 connected After the first liquid-cooling connector, the first connecting terminal, the first electrical connector, the second liquid-cooling connector 46, the second connecting terminal 48, the second electrical connector 47, the adapter 73, and the first current collecting member 81 and the second current collecting member 82 of the liquid-cooling tube are removed from the main frame 61, the main frame 61 is detached from the side wall of the cavity. The operation and maintenance personnel can hold the handheld frame 65 to remove the bridge module 60 as a whole from the inspection port for separate maintenance operations, thereby avoiding the need to remove all the switching modules 20, the CPU module 30, and the GPU module 40 from the front cavity 101, making the maintenance of the bridge module 60 more convenient.

[0102] In this embodiment, an inspection port is provided on the box body 10 and a handheld rack 65 is provided on the main frame body 61, which can facilitate operation and maintenance personnel to take and place the bridge module 60, thereby making it easier to maintain the server chassis 100 during long-term operation.

[0104] In this embodiment, the box body 10 is also provided with a support frame 13, which is arranged at the bottom of the main box body 11 and connected to the main box body 11. The support frame 13 can provide stable support for the main box body 11 and the various module modules in the cavity, so that the overall structure of the server chassis 100 is more stable when it is arranged during transportation.

[0105] The support frame 13 is provided with an air duct 133 and forms an air inlet 1301 at the front end, and an air outlet 1302 connected to the rear cavity 102 at the rear end. When the server chassis 100 is running, the fan on the rear plug-in box module 90 runs to draw air from the front cavity 101 and the rear cavity 102, so that the external air can pass through the interior of each module along the front cavity 101 and then flow to the rear cavity 102 through the air-cooling flow channel 621 in the bridge module 60 and be discharged from the fan. The external air can also flow from the air inlet 1301 to the air outlet 1302 along the air duct 133 and enter the rear cavity 102, thereby cooling and dissipating the power board 71, cables, power supply unit 72 and other components in the rear cavity 102, so that the rear cavity 102 can have a better cooling and heat dissipation effect, and the overall heat dissipation performance of the server chassis 100 is further improved.

The liquid collecting trough 131 is in communication with the rear chamber 102 and can collect leaked liquid in the rear chamber 102. The collected liquid is then discharged along the flow guide tube 132.

The flow guide tube 132 is arranged in the air duct 133 for convenient arrangement.
