[0024] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0025] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc. may refer to different or the same objects.

[0026] As mentioned above, in some conventional high-speed serial computer expansion bus standard (PCIe) expansion boxes, the expansion card is usually set at the back of the chassis. When connecting to a server with front-outlet cables, the cable needs to pass through the entire chassis and then connect to the server at the front of the chassis, which makes cable deployment difficult. In addition, when configuring a network card, it is also necessary to place the network card at the back. The rear-placed network card and network optical module will affect the stability of the system due to poor heat dissipation.

[0027] Embodiments of the present disclosure provide a server expansion box and a server device. The server expansion box includes a chassis body, a carrier board, a plurality of expansion cards, and a plurality of data interfaces. The chassis body includes a accommodating cavity and a first opening. The first opening is disposed on the front side of the chassis body and is connected to the accommodating cavity. The carrier board is disposed in the accommodating cavity adjacent to the first opening. A plurality of expansion cards are detachably coupled to the carrier board. A plurality of data interfaces are disposed at the first opening and are electrically connected to the carrier board. With this arrangement, the carrier board and a plurality of expansion cards are disposed adjacent to the front side of the chassis, and the data interface is directly disposed at the first opening. When connected to a server host with front-outlet wiring, the data interface of the server host and the server expansion box is connected via a cable on the outside of the chassis body. The cable does not need to be disposed inside the chassis, and deployment is more convenient and direct. In addition, a plurality of data interfaces are disposed on the front side of the chassis, avoiding the high-temperature heat source on the rear side of the chassis. The heat dissipation performance of the data interface is good, which can improve the stability of the system. The following will be combined with Figures 1 to 9 To describe the principles of the present disclosure in detail.

[0028] like Figure 1 and Figure 2As shown, the server expansion box can provide more resource expansion capabilities for the computer system, such as multiple input / output options, storage space or network connection capabilities. The server expansion box includes a chassis body 10, a carrier board 20, multiple expansion cards 40 and multiple data interfaces 21.

[0029] like Figure 2 As shown, the chassis body 10 includes a receiving cavity 100 and a first opening 11. The receiving cavity 100 is used to install various hardware. The first opening 11 is arranged at the front side of the chassis body 10 and communicates with the receiving cavity 100.

[0030] The carrier board 20 is disposed inside the chassis body 10 and near the first opening 11. The carrier board 20 may be provided with various types of slots, and expansion cards 40 of different specifications and uses may be inserted into the slots. Here, since the carrier board 20 is adjacent to the first opening 11, the expansion card 40 mounted on the carrier board 20 is also located at a position of the chassis body 10 adjacent to the first opening 11, thereby shortening the signal transmission path from the expansion card 40 to the external data interface. In this way, it is helpful to reduce signal attenuation, improve data transmission speed, and reduce the complexity of cable layout.

[0031] like Figure 2 and Figure 3 As shown, multiple expansion cards 40 are detachably coupled to the carrier board 20. For example, the expansion card 40 is coupled to the carrier board 20 through a specific interface, so that a plug-and-play function can be realized. In addition, the user can freely select and configure the type and quantity of the required expansion card 40 according to actual needs, which can improve the application range of the server expansion box.

[0032] As an example, the expansion card 40 can be a network adapter. In this way, multiple expansion cards 40 can improve network performance.

[0033] As another example, the expansion card 40 may be a graphics processing unit. In this way, multiple expansion cards 40 may accelerate image rendering tasks.

[0034] It should be understood that in other embodiments, the expansion card 40 may also be a solid state drive or a processing unit, and the user may select the number and type of expansion cards 40 as needed, and the present disclosure is not intended to be limiting in this regard.

[0035] like Figure 1 and Figure 2As shown, a plurality of data interfaces 21 are provided at the first opening 11 and are electrically connected to the carrier board 20. In some embodiments, the data interface 21 may be a coherent direct-connect optical fiber interface. In this way, the data interface 21 can perform high-speed data transmission between the server host and the server expansion box, and has high bandwidth, strong anti-interference capability and good spectrum efficiency, which can simplify the network architecture.

[0036] In this way, the server host with front-side outlets can be connected to the server expansion box using external cables, without the need to place the cables inside the chassis body 10. Arranging cables on the front side of the chassis body 10 can also avoid the confusion of wire harnesses caused by too many cables inside the chassis body 10. In addition, placing the data interface 21 on the front side of the chassis body 10 can avoid high-temperature areas of the chassis body 10. For example, avoid the power module 53 and the fan module located at the rear of the chassis body 10. Therefore, the data interface 21 has better heat dissipation performance and can improve the stability of the system.

[0037] In some embodiments, Figure 4 As shown, the server expansion box further includes a tray assembly 30. The tray assembly 30 is disposed in the accommodating cavity 100 and coupled to the bottom of the carrier plate 20. The tray assembly 30 can provide a mounting platform for the carrier plate 20, and can enhance the mechanical strength of the carrier plate 20, so that it can bear the weight of multiple expansion cards 40 and other components mounted thereon, and reduce potential failures caused by vibration or external impact.

[0038] In some embodiments, Figure 3 and Figure 5 As shown, a stopper 41 is provided at one end of each expansion card 40 near the first opening 11. The stopper 41 is coupled to the tray assembly 30 to limit the position of the expansion card 40 and prevent it from being moved or loosened unnecessarily during operation. With this arrangement, the stopper 41 can ensure good contact between the expansion card 40 and the carrier board 20, reducing poor circuit contact caused by loose expansion card 40.

[0039] In some embodiments, Figure 5 As shown, a support frame 74 can be provided in the accommodating cavity 100. The support frame 74 is installed inside the chassis body 10 and can abut against a plurality of expansion cards 40. In this way, the support frame 74 can provide an additional support position for the expansion card 40, thereby preventing the expansion card 40 from being subjected to excessive pressure and causing deformation or damage. In addition, the support frame 74 can maintain the parallel arrangement of the plurality of expansion cards 40 and increase the stability of the expansion card 40. When a new expansion card 40 needs to be added, the technician only needs to insert the expansion card 40 into the card slot on the carrier plate 20 until the stopper 41 contacts the tray assembly 30 and / or the support frame 74.

[0040] In some embodiments, Figure 3 , Figure 5 as well as Figure 6 As shown, the carrier plate 20 is provided with a plurality of through holes 22 spaced apart from each other, and the plurality of through holes 22 correspond one by one to the stopper 41 on the expansion card 40. Here, the stopper 41 may be, for example, a blocking piece, which may penetrate the corresponding through hole 22 on the carrier plate 20 and contact the tray assembly 30 located below. In this way, the stopper 41 may be tightly connected to the tray assembly 30, and the expansion card 40 may be prevented from being displaced or loosened during operation, thereby improving the stability and efficiency of data transmission.

[0041] It should be understood that the carrier board 20 may arrange circuits in the area outside the plurality of through holes 22 , so as to achieve data transmission with the plurality of data interfaces 21 .

[0042] In some embodiments, Figures 4 to 7 As shown, the tray assembly 30 includes a tray panel 31 and a support member 32. The tray panel 31 can provide a mounting plane for the carrier plate 20. A plurality of limiting portions 310 can be provided on the tray panel 31, and the plurality of limiting portions 310 can be connected to the stopper portions 41 of the plurality of expansion cards 40 in a one-to-one correspondence. In this way, the tray panel 31 can fix the positions of the plurality of expansion cards 40 to prevent them from being moved or loosened unnecessarily in the chassis.

[0043] As an example, the limiting portion 310 may be a limiting groove, and the end of the stopping portion 41 may be inserted into the limiting groove, thereby limiting the position of the stopping portion 41 .

[0044] As another example, the limiting portion 310 may be a limiting step, and the end of the stopping portion 41 may abut against the limiting step, thereby limiting the position of the stopping portion 41 .

[0045] It should be understood that in other embodiments, a plurality of structures cooperating with the stop portion 41 may be formed on the tray panel 31 through a stamping and bending process, and then the stop portion 41 and the limiting portion 310 may be connected together through pins or screws. The present disclosure does not intend to limit the specific structural form of the limiting portion.

[0046] like Figure 4 and Figure 7As shown, the support member 32 is disposed on a side of the tray panel 31 away from the carrier plate 20 and coupled to the tray panel 31. The number of the support members 32 can be multiple, and the multiple support members 32 can fix the tray panel 31 in the chassis body 10 and keep a certain distance between the tray panel 31 and the bottom surface of the chassis body 10. In this way, an area for arranging cables or ventilation can be formed on the side of the tray panel 31 away from the carrier plate 20, thereby rationally utilizing the space inside the chassis body 10.

[0047] In some embodiments, Figure 8 As shown, the chassis body 10 further includes a second opening 12. The second opening 12 is disposed at the rear side of the chassis body 10 and communicates with the accommodating chamber 100. On this basis, the server expansion box further includes a first fan module 51 and a power module 53. The first fan module 51 and the power module 53 are disposed at the second opening 12, and the first fan module 51 is located at the top, while the power module 53 is disposed below the first fan module 51.

[0048] In this way, the first fan module 51 and the power module 53 are separated from the expansion cards 40 and the carrier board 20 as high heat generating units, so that the problem of excessive heat concentration can be avoided. By placing the first fan module 51 and the power module 53 at the second opening 12 on the rear side of the chassis and separating them from the expansion cards 40 and the carrier board 20, the heat distribution between the components can be made more uniform, reducing the risk of local overheating, thereby improving the stability of the system during operation.

[0049] In addition, the height of the first fan module 51 corresponds to the plurality of expansion cards 40 and the carrier board 20. When the first fan module 51 is in operation, the airflow can be directly directed to the surfaces of the plurality of expansion cards 40 and the carrier board 20, thereby promoting rapid heat dissipation. When in operation, the first fan module 51 draws air from the first opening 11, and after the air passes through the surfaces of the expansion cards 40 and the carrier board 20, it is discharged from the chassis body 10 along the second opening 12, thereby discharging heat from the chassis body 10.

[0050] like Figure 8 As shown, the power module 53 is arranged below the first fan module 51, which can not only fully utilize the limited space resources at the second opening 12, but also enable the power module 53 to be well cooled to prevent the heat generated by it from adversely affecting the expansion card 40 and the carrier board 20 above.

[0051] In some embodiments, Figure 7As shown, the server expansion box further includes a partition 54. The partition 54 is disposed above the power module 53 and corresponds to the tray panel 31. The partition 54 and the tray panel 31 divide the accommodating chamber 100 into an upper chamber 101 and a lower chamber 102. In this way, the partition 54 and the tray panel 31 can form two independent air flow channels between the upper chamber 101 and the lower chamber 102.

[0052] like Figure 7 As shown, the carrier board 20 and the plurality of expansion cards 40 are arranged in the upper chamber 101, and the heat dissipated by the carrier board 20 and the plurality of expansion cards 40 during operation can be discharged through the air flowing in the upper chamber 101. The first fan module 51 is installed at the rear side of the chassis body 10 and corresponds to the upper chamber 101. The first fan module 51 can promote air to flow into the interior of the chassis body 10 from the first opening 11, and the air passes through the surfaces of various components in the upper chamber 101 and is then discharged along the second opening 12.

[0053] The power module 53 is installed in the lower chamber 102. Since the power module 53 is the main heat source, separating it from the upper chamber 101 can prevent the heat generated by it from adversely affecting other sensitive electronic components. In addition, the heat emitted by the power module 53 can be discharged with the air flowing in the lower chamber 102.

[0054] In some embodiments, Figure 4 and Figure 7 As shown, the server expansion box also includes a second fan module 52. The second fan module 52 is disposed in the lower chamber 102 and is coupled to the chassis body 10. The second fan module 52 is specifically responsible for the air circulation of the lower chamber 102, and can discharge the heat generated when the power module 53 is working. When the second fan module 52 is running, air can be sucked in from the first opening 11 on the front side of the chassis body 10, and the air passes through the surface of the power module 53 and then discharged through the second opening 12 on the rear side of the chassis body 10. In this way, the temperature in the lower chamber 102 can be reduced, and the working efficiency and life of the power module 53 can be improved.

[0055] In some embodiments, Figure 4 As shown, the server expansion box also includes an air guide 55. The air guide 55 surrounds at least a portion of the power module 53, and includes an air inlet 551 and an air outlet that are relatively arranged. The air inlet 551 corresponds to the first opening 11, and the air outlet corresponds to the second opening 12. The air in the lower chamber 102 can enter the air guide 55 through the air inlet 551, and then flow to the second opening 12 through the air outlet, which can form an efficient airflow path, so that the surface of the power module 53 can be fully cooled, greatly improving its heat dissipation effect.

[0056] When the second fan module 52 is working, the second fan module 52 will inhale cold air from the first opening 11, and the cold air will enter the lower chamber 102. Due to the existence of the air guide 55, the cold air flows to the surface of the power module 53. The hot air after heat exchange can be discharged along the air outlet of the air guide 55 and discharged from the chassis body 10 through the second opening 12. In this way, heat accumulation in the lower chamber 102 can be avoided, and the power module 53 can be kept at a lower operating temperature, thereby improving the efficiency and life of the power module 53.

[0057] In some embodiments, Figure 5 As shown, the server expansion box also includes a mounting bracket 73. The mounting bracket 73 is arranged at the second opening 12, and includes a plurality of mounting areas 730 for fixing the first fan module 51 and the power module 53. In this way, the mounting bracket 73 can firmly fix the first fan module 51 and the power module 53 to prevent them from being displaced or loosened due to vibration or external force, thereby ensuring reliability and safety in long-term operation. In addition, the mounting bracket 73 can make the installation and removal process of the first fan module 51 and the power module 53 simpler and faster. The technician can add or remove components and perform necessary upgrades or maintenance work without destroying the overall structure of the chassis body 10.

[0058] In some embodiments, the mounting bracket 73 can also provide greater flexibility for technicians, and the number of first fan modules 51 and power modules 53 can be adjusted according to actual needs. For example, when the power of multiple expansion cards 40 and carrier boards 20 is high, the number of first fan modules 51 and power modules 53 can be increased to meet higher heat dissipation and power supply requirements. More first fan modules 51 can provide stronger airflow, so that the expansion cards 40 and carrier boards 20 maintain a suitable operating temperature under high load. The additional power modules 53 can provide more sufficient power support to avoid performance bottlenecks or system instability caused by insufficient power.

[0059] In the case where the power of the multiple expansion cards 40 and the carrier board 20 is low, the technician may choose to reduce the number of the first fan modules 51 and the power supply modules 53 to reduce unnecessary energy consumption and lower operating costs.

[0060] By flexibly adjusting the number of the first fan modules 51 and the power supply modules 53, the server expansion box can achieve the best balance between performance and energy efficiency in different application scenarios, ensuring that the system is always in an efficient and stable operating state.

[0061] In some embodiments, Figure 1 and Figure 2As shown, the server expansion box also includes an input / output module 71 (I / O module). The input / output module 71 is disposed at the first opening 11 and is electrically connected to the carrier board 20. The input / output module 71 performs functions such as data transmission, signal exchange, and power management. By arranging it at the first opening 11, it is convenient to access and manage cables.

[0062] In some embodiments, Figure 1 and Figure 2 As shown, the server expansion box also includes a filter 72. The filter 72 is disposed at the first opening 11 and coupled to the chassis body 10. In this way, the filter 72 can prevent debris carried by air flow from entering the interior of the chassis body 10 through the first opening 11, thereby protecting the working environment of the internal electronic components. In addition, the filter 72 can also improve electrical safety and prevent technicians from accidentally touching internal sensitive components during operation or maintenance.

[0063] When the server expansion box is running, the filter 72 can intercept dust, fibers and other tiny particles to prevent them from entering the chassis with the airflow and attaching to the expansion card 40, the carrier board 20 or other components. If these debris accumulate for a long time, it may cause a decrease in heat dissipation efficiency, increase the risk of overheating, and even cause serious faults such as short circuits. By installing the filter 72, the air entering the chassis body 10 can be relatively clean, maintaining the stability and cleanliness of the internal environment, thereby extending the service life of electronic components and the reliability of the system.

[0064] In addition, during routine maintenance or adjustment, technicians need to connect or disconnect cables at the first opening 11. The filter 72 can provide a physical barrier to prevent technicians from accidentally touching the charged electronic components inside, thereby avoiding electric shock hazards or damaging sensitive circuits.

[0065] In some embodiments, Figure 2 , Figure 3 and Fig. 9 As shown, the server expansion box also includes a liquid cooling system 60. The liquid cooling system 60 is disposed in the accommodating cavity 100 and is coupled to the plurality of expansion cards 40. The liquid cooling system 60 can remove the heat generated by the electronic components inside the chassis through the circulation of the coolant, so that the plurality of expansion cards 40 can maintain a suitable operating temperature under high-performance working conditions. The liquid cooling system 60 has a higher cooling efficiency and can meet the heat dissipation requirements of high-performance servers.

[0066] In some embodiments, Fig. 9As shown, the liquid cooling system 60 includes a liquid inlet pipe 61, a liquid return pipe 62, and a liquid cooling adapter 63. The liquid cooling adapter 63 is connected to the liquid inlet pipe 61 and the liquid return pipe 62, and the liquid cooling adapter 63 includes a plurality of liquid inlets 631 and a plurality of liquid outlets 632, and the plurality of liquid inlets 631 and the plurality of liquid outlets 632 are coupled to the plurality of expansion cards 40 in a one-to-one correspondence.

[0067] When the liquid cooling system 60 is running, the coolant is pumped into the liquid cooling adapter 63 by an external cooling device (such as a chiller) through the liquid inlet pipe 61. The liquid cooling adapter 63 is provided with a flow channel inside, which can distribute the coolant to multiple liquid outlets 632, and each liquid outlet 632 is connected to a cold plate built into the expansion card 40. When the coolant flows through the cold plate, it can absorb and take away the heat generated by the expansion card 40. In this process, the coolant gradually heats up from a low temperature and carries away a large amount of heat energy.

[0068] Subsequently, the coolant that has absorbed the heat flows into the corresponding liquid inlet 631 of the liquid cooling adapter 63, and then enters the liquid return pipe 62. The liquid return pipe 62 guides the heated coolant back to the external cooling device, where the heat is dissipated to the environment through a radiator or other cooling means, so that the coolant is cooled again. After the cooling treatment, the coolant is pumped back to the liquid inlet pipe 61 again to start a new round of circulation. During the whole process, the coolant is always in a closed loop to avoid direct contact with electrical components, while ensuring efficient heat transfer.

[0069] In some embodiments, Figure 2 , Figure 3 and Fig. 9 As shown, the liquid cooling adapter is arranged on the side of the multiple expansion cards 40 away from the first opening 11, and the multiple liquid inlets 631 and the multiple liquid outlets 632 are arranged on the side of the liquid cooling adapter 63 facing the multiple expansion cards 40. In this way, the multiple liquid inlets 631 and the multiple liquid outlets 632 can directly face the expansion cards 40, and the liquid inlets 631 and the liquid outlets 632 can be connected to the expansion cards 40 through the liquid guide tube 64. Here, the liquid guide tube 64 can be arranged in a nearly straight line, and does not need to be arranged in a zigzag manner inside the chassis body 10, which can not only save space inside the chassis body 10, but also improve the flow efficiency of the coolant.

[0070] In a second aspect of the present disclosure, a server device is provided, which includes a server host and any one of the above-mentioned server expansion boxes, wherein a plurality of data interfaces 21 of the server expansion box are coupled to the server host.

[0071] In the server expansion box of the server device, the chassis body 10 includes a accommodating cavity 100 and a first opening 11. The first opening 11 is arranged on the front side of the chassis body 10 and is connected to the accommodating cavity 100. The carrier plate 20 is arranged in the accommodating cavity 100 adjacent to the first opening 11. A plurality of expansion cards 40 are detachably coupled to the carrier plate 20. A plurality of data interfaces 21 are arranged at the first opening 11 and are electrically connected to the carrier plate 20. With this arrangement, the carrier plate 20 and the plurality of expansion cards 40 are arranged adjacent to the front side of the chassis, and the data interface 21 is directly arranged at the first opening 11. When connected to a server host with a front outlet, the server host is connected to the data interface 21 through a cable on the outside of the chassis, and the cable does not need to be arranged inside the chassis, and the deployment is more convenient and direct. In addition, the plurality of data interfaces 21 are arranged on the front side of the chassis body 10, avoiding the high-temperature heat source on the rear side of the chassis, and the heat dissipation performance of the data interface 21 is good, which can improve the stability of the system.

[0072] Embodiments of the present disclosure are also embodied in the following examples.
