Description

Technical Field

[0001] The utility model relates to the technical field of servers, and particularly relates to a support component and a server. Background Art

[0002] A cold plate GPU is a GPU heat dissipation solution based on liquid cooling technology. Compared with the traditional air cooling solution, the cold plate GPU has higher heat dissipation efficiency and lower noise level. With the continuous improvement of GPU performance, the heat generated by the GPU during high-load operation is also increasing. Therefore, GPU cold plates are more and more widely used in GPU heat dissipation to ensure better heat dissipation effect.

[0003] In order to support the weight of the cold plate GPU, a bracket structure is usually designed at the tail end of the GPU board to ensure its stability and safety. However, there are still some potential risks in the current tail-end bracket structure. For example, the strength of the bracket structure is insufficient to bear the weight of the cold plate GPU, and the tail-end bracket affects the plugging and unplugging of the pipelines of the cold plate GPU, etc., thus affecting the stability and maintenance convenience of the server. Summary of the Utility Model

Detailed implementation manners

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0054] With the continuous development of fields such as data centers and artificial intelligence, the demand for high-performance computing is also increasing. Among them, as an important computing accelerator, the performance and power consumption of GPUs have attracted much attention. Based on this, cold plate GPUs, as an efficient heat dissipation solution, are increasingly applied to the heat dissipation systems of servers.

[0055] The weight of a cold plate GPU has a certain impact on its performance. An overly heavy cold plate GPU may increase the overall load of the server and reduce the stability and performance of the server. Therefore, when designing a cold plate GPU, its weight problem needs to be considered and corresponding measures should be taken to solve it.

[0056] At present, in order to support the weight of the cold plate GPU, it is necessary to design a tail-end bracket structure to ensure the stability and safety of the cold plate GPU. For the cold plate GPU, since a liquid cooling method is adopted, it is necessary to set up a joint structure to connect the pipeline, and the pipeline is connected to an external cold source to ensure the normal heat dissipation. However, the strength of the traditional bracket structure can no longer bear the weight of the cold plate GPU, which in turn affects the stability of the server. Moreover, the bracket structure also affects the plugging and unplugging of the pipeline, resulting in a significant reduction in the convenience of later maintenance.

[0057] Based on this, the present utility model provides a support component and a server. The support component is arranged in the chassis of the server and is used to support the GPU board to improve the stability of the server and the convenience of maintenance. The above support component and server will be described in detail below with reference to specific embodiments.

[0058] Refer to Figure 1 , the server in the embodiment of the present utility model may include a chassis 100, a board tray module 200, a GPU board 300, and a support component 400. Among them, the board tray module 200, the GPU board 300, and the support component 400 are all arranged in the chassis 100.

[0059] Refer to together Figure 1 and Figure 2 , the chassis 100 may include a bottom plate 110 and two oppositely arranged side plates 120. The two side plates 120 are respectively connected to the bottom plate 110 to enclose an accommodation space for accommodating the above board tray module 200, GPU board 300, and support component 400. The board tray module 200 is arranged on the bottom plate 110, and the GPU board 300 and the support component 400 are both arranged on the side of the tray board 210 away from the bottom plate 110. Specifically, there may be multiple GPU boards 300, for example. The board tray module 200 includes a tray board 210, and the tray board 210 is provided with connection ends 211 corresponding to the multiple GPU boards 300 one by one. Each GPU board 300 is respectively inserted into the connection end 211 to realize the connection with the tray board 210.

[0060] In some embodiments, continue to refer to Figure 1, the support component 400 includes a bracket 410 and a crossbeam module 420. The bracket 410 is fixedly installed at the tail end of the GPU board 300. At this time, the bracket 410 and the GPU are arranged in the first direction. The crossbeam module 420 is located on the side of the bracket 410 facing the tray board 210. The crossbeam module 420 is fixedly connected to the bracket 410 and the tray board 210 respectively. At this time, the bracket 410 and the crossbeam module 420 are arranged in the second direction, and the second direction can also be regarded as the height direction of the GPU board 300. In addition, the crossbeam module 420 extends in the third direction, and both ends of the crossbeam module 420 are fixedly connected to the two side plates 120 respectively. It should be noted that the first direction is perpendicular to the second direction, and the third direction is perpendicular to the first direction and perpendicular to the second direction.

[0061] Reference Figure 3 , the bracket 410 may include a first connection portion 411, a second connection portion 412 and a third connection portion 413. The first connection portion 411 and the second connection portion 412 are arranged at intervals in the second direction. The third connection portion 413 is connected between the first connection portion 411 and the second connection portion 412, and the third connection portion 413 is located on the side of the first connection portion 411 away from the GPU board 300, so that the bracket 410 is generally in a U-shaped structure as a whole.

[0062] The first connection portion 411 is fixedly connected to the tail end of the GPU board 300. Exemplarily, a first mounting plate 4111 is provided at one end of the first connection portion 411 close to the GPU board 300, and the first mounting plate 4111 is parallel to the tail end side plate 120 of the GPU board 300. The first mounting plate 4111 is provided with a first mounting hole 4112, and the GPU board 300 is correspondingly provided with a first threaded hole 310. When fixing the first connection portion 411 to the GPU board 300, the first mounting plate 4111 can be attached to the GPU board 300, and then the screw is passed through the first mounting hole 4112 and fixed in the first threaded hole 310, so as to realize the fixation of the first connection portion 411 to the GPU board 300.

[0063] Similarly, the second connection portion 412 is fixedly connected to the tail end of the GPU board 300. A second mounting plate 4121 is provided at one end of the second connection portion 412 close to the GPU board 300, and the second mounting plate 4121 is parallel to the tail end side plate 120 of the GPU board 300. The second mounting plate 4121 is provided with a second mounting hole 4122, and the GPU board 300 is correspondingly provided with a second threaded hole 320. When fixing the second connection portion 412 to the GPU board 300, the second mounting plate 4121 can be attached to the GPU board 300, and then the screw is passed through the second mounting hole 4122 and fixed in the second threaded hole 320, so as to realize the fixation of the second connection portion 412 to the GPU board 300.

[0064] Further, with reference to Figure 3 and Figure 4 , a joint structure 330 for connecting the pipeline 500 is also provided at the tail end of the GPU board 300. The joint structure 330 may include, for example, a first joint structure for connecting the liquid inlet pipeline and a second joint structure for connecting the liquid outlet pipeline. The liquid inlet pipeline, the liquid outlet pipeline, and the GPU board 300 form a closed-loop path for the coolant to flow, so as to take out the heat of the GPU board 300 through the circulating liquid outside the GPU board 300, and then output it to the cooling system outside the chassis 100.

[0065] The first connecting portion 411 and the second connecting portion 412 are located on both sides of the two joint structures 330. That is, along the second direction, the two joint structures 330 are located between the first connecting portion 411 and the second connecting portion 412. Since the first connecting portion 411 and the second connecting portion are spaced apart, an avoidance space 414 for avoiding the pipeline 500 is formed between the first connecting portion 411 and the second connecting portion 412. One end of the pipeline 500 is connected to the cold source, and the other end can be connected to the joint structure 330 after passing through the avoidance space 414.

[0066] It can be understood that in the server of this embodiment, by providing the avoidance space 414 in the bracket 410, it is convenient for the pipeline 500 to pass through the avoidance space 414 and then be inserted and unplugged with the joint structure 330, improving the convenience of insertion and unplugging. In addition, setting the crossbeam module 420 at the bottom of the bracket 410 will not interfere with the insertion and unplugging of the pipeline 500, further improving the convenience of maintenance. In addition, by using the combination of the fixed connection between the bracket 410 and the crossbeam module 420, the overall strength of the support assembly 400 is improved, ensuring the stability of the GPU board 300 in the chassis and improving the stability of the server.

[0067] In addition, with reference to Figure 3 and Figure 5 , a plug-in portion 340 for connecting the power cable 600 is also provided at the tail end of the GPU board 300. The power cable 600 can be connected to the GPU board 300 through the plug-in portion 340, so as to supply power to the GPU board 300. Based on this, the third connecting portion 413 is provided with a clamping module 415. When the power cable 600 passes through the third connecting portion 413, the clamping module 415 can fix the power cable 600, so as to ensure that the power cable 600 can be stably connected to the GPU board 300 and avoid loosening or breaking during use.

[0068] Specifically, as Figure 5As shown, the clamping module 415 may include, for example, two elastic clips 4151, each of which is an L-shaped structure, one end of the elastic clip 4151 is fixed to the third connection portion 413, and the other end is kept at a certain distance from the third connection portion 413, so as to reserve space for fixing the power cable 600. The two elastic clips 4151 are arranged opposite to each other, and when the power cable 600 is connected to the plug-in portion 340 against the third connection portion 413, the two elastic clips 4151 can be attached to the side of the power cable 600 away from the third connection portion 413, so as to cooperate with the third connection portion 413 to fix the power cable 600. When the power cable 600 needs to be removed, the elastic clip 4151 only needs to be manually opened to both sides to remove the clamping force acting on the power cable 600, and the power cable 600 can be removed.

[0069] Continue to refer Figure 3 and Figure 4 , the third connection part 413 is also provided with a buffer module 416. As mentioned above, the pipeline 500 can pass through the avoidance space 414 between the first connection part 411 and the second connection part 412 to connect with the joint structure 330. At this time, the pipeline 500 can be in contact with the third connection part 413, and the third connection part 413 can also play a role in limiting the position of the pipeline 500. In order to ensure the strength of the bracket 410, the bracket 410 is generally made of a material with a higher hardness. When the pipeline 500 is in contact with the third connection part 413, the buffer module 416 is located between the third connection part 413 and the pipeline 500 to protect the pipeline 500.

[0070] As an optional implementation, the buffer module 416 is made of foam, which can cover the third connection portion 413 along the second direction. Since the surface of the third connection portion 413 is covered with soft material, the impact of vibration and friction on the pipeline 500 can be effectively buffered.

[0071] Continue to refer Figure 3 A third mounting plate 4131 is also provided on one side of the third connecting portion 413 close to the beam module 420 . The third mounting plate 4131 is parallel to the bottom plate 110 . The third mounting plate 4131 can be fixedly connected to the beam module 420 , thereby fixing the bracket 410 and the beam module 420 .

[0072] refer to Figure 6The cross beam module 420 includes a first connecting member 421 and a second connecting member 422, which are stacked along the second direction and fixedly connected to each other. Exemplarily, the first connecting member 421 is provided with a plurality of first rivet holes 424 arranged along the third direction, and the second connecting member 422 is provided with fixing holes 425 corresponding to the plurality of first rivet holes 424. At this time, the first connecting member 421 and the second connecting member 422 can be fixed by riveting through a rivet 423 that passes through the fixing holes 425 and is fixed to the first rivet holes 424, so as to enhance the fixing effect between the two.

[0073] The first connecting member 421 and the second connecting member 422 can both be sheet metal parts. It can be understood that by providing a double-layer connecting member, the overall strength of the beam module 420 is improved. When the GPU board 300 is supported by the bracket 410 and the beam module 420, the stability of the GPU board 300 in the chassis 100 can be better guaranteed.

[0074] Continue to refer Figure 6 The first connecting member 421 may specifically include a first transverse plate 4211, a longitudinal plate 4212, and a second transverse plate 4213, wherein the first transverse plate 4211 and the second transverse plate 4213 are arranged in parallel. Along the first direction, the second transverse plate 4213 is located at a side of the first transverse plate 4211 away from the GPU board 300, and along the second direction, the first transverse plate 4211 and the second transverse plate 4213 are arranged at intervals, and the second transverse plate 4213 is located between the first transverse plate 4211 and the tray board 210. Both sides of the longitudinal plate 4212 are respectively vertically connected to the first transverse plate 4211 and the second transverse plate 4213, so that the first connecting member 421 has a stepped structure.

[0075] The second connecting member 422 may specifically include a connecting plate 4221 and a plurality of connecting ear plates 4222, wherein the plurality of connecting ear plates 4222 are arranged along the third direction, and each connecting ear plate 4222 is fixedly connected to the connecting plate 4221. The connecting plate 4221 is parallel to the longitudinal plate 4212, and the connecting ear plates 4222 are parallel to the first transverse plate 4211. In addition, the first transverse plate 4211 and the longitudinal plate 4212 are both provided with a plurality of first rivet holes 424, each connecting ear plate 4222 is provided with a fixing hole position 425, and the connecting plate 4221 is also provided with a plurality of fixing hole positions 425. When the first connecting member 421 is fixedly connected to the second connecting member 422, the first transverse plate 4211 and the connecting ear plates 4222 are fixed by riveting with the rivets 423, and the longitudinal plate 4212 and the connecting plate 4221 are fixed by riveting with the rivets 423.

[0076] The connecting plate 4221 and the connecting ear plate 4222 can be of an integral structure, and the first transverse plate 4211, the longitudinal plate 4212, and the second transverse plate 4213 can also be of an integral structure to improve the strength of the structural member. In this way, by carrying out blind riveting fixation on the first connecting member 421 and the second connecting member 422 in different directions, the fixation effect between the first connecting member 421 and the second connecting member 422 can be further improved, thereby achieving the effect of improving the strength of the crossbeam module 420.

[0077] Reference Figure 7 and Figure 8 , the crossbeam module 420 is provided with multiple groups of positioning modules 426, and the multiple groups of positioning modules 426 are arranged at intervals along the third direction. When Figure 3 the third mounting plate 4131 in is connected to the crossbeam module 420, positioning and fixation can be carried out between one or more groups of positioning modules 426 and the crossbeam module 420. Taking the bracket 410 connected to the crossbeam module 420 through one group of positioning modules 426 as an example, as an optional implementation scheme, reference Figures 7 to 10 , each group of positioning modules 426 can include a positioning hole 4261 and a third threaded hole 4262 provided on the first transverse plate 4211. Correspondingly, the third mounting plate 4131 is provided with a positioning post 417 and a third mounting hole position 418. Among them, the positioning post 417 is directly opposite to the positioning hole 4261, and the third mounting hole position 418 is directly opposite to the third threaded hole 4262. When installing the third mounting plate 4131 and the crossbeam module 420, the third mounting plate 4131 can be attached to the first transverse plate 4211, the positioning post 417 is snapped into the positioning hole 4261, and then the screw passing through the third mounting hole position 418 is fixed in the third threaded hole 4262, thereby fixing the third mounting plate 4131 and the crossbeam module 420.

[0078] The third threaded hole 4262 can be, for example, a self-tapping hole, and the third mounting plate 4131 and the crossbeam module 420 can be fixed by a press riveting screw.

[0079] Alternatively, the positioning module can include a positioning post (not shown in the figure) provided on the first transverse plate 4211. Correspondingly, the third mounting plate 4131 is provided with a positioning hole (not shown in the figure), and precise positioning between the first transverse plate 4211 and the third mounting plate 4131 is achieved through the positioning post and the positioning hole.

[0080] Furthermore, when multiple groups of positioning modules 426 are arranged at intervals, the spacing between two adjacent groups of positioning modules 426 can be 20.32 mm. Since multiple GPU boards 300 are placed in the chassis 100, the multiple GPU boards 300 are arranged along the third direction, and the rear end of each GPU board 300 is fixedly connected with a bracket 410. In other words, in the chassis 100, there are multiple brackets 410, and the multiple brackets 410 are respectively fixedly connected to the crossbeam module 420, so as to support each GPU board 300. When the spacing between adjacent positioning modules is designed to be 20.32 mm, it can meet the installation of GPU boards 300 of different widths, thereby improving the applicability of the support assembly 400 in this embodiment.

[0081] In addition, an indicator arrow 4214 is provided on the side of the first transverse plate 4211 facing away from the bottom plate 110. The indicator joint 4214 points in the direction from the first transverse plate 4211 to the second transverse plate 4213, thereby indicating the installation direction between the first connecting member 421 and the second connecting member 422, thereby preventing the second connecting member 422 from being installed in the wrong direction and affecting the overall strength of the beam module 420.

[0082] Continue to refer Figure 7 and Figure 8 , the first cross plate 4211 is connected to the fourth mounting plate 427 on both sides along the third direction, and the second cross plate 4213 is connected to the fifth mounting plate 428 on both sides along the third direction, wherein the fourth mounting plate 427 and the fifth mounting plate 428 are respectively provided with a fourth threaded hole 4271 and a fifth threaded hole 4281. In addition, a plurality of rivet screws 429 are riveted on the second cross plate 4213, and the rivet screws 429 protrude from the surface of the second cross plate 4213 toward the tray board 210. The cross beam module 420 is fixed to the side plate 120 through the fourth mounting plate 427 and the fifth mounting plate 428, and is fixed to the tray board 210 through a plurality of rivet screws 429.

[0083] Specifically, refer to Figure 11 The tray board 210 is provided with a first transfer hole, and a first rivet stud 213 is fixed in the first transfer hole. The rivet screw 429 is fixed in the first rivet stud 213, so as to achieve the fixation between the beam module 420 and the tray board 210. The side wall of the chassis 100 is provided with two fixing screws 121 penetrating the side wall, one of which is fixed in the fourth threaded hole 4271, and the other is fixed in the fifth threaded hole 4281.

[0084] It can be understood that the press rivet screw 429 fixes the crossbeam module 420 and the tray board 210 in the second direction, and the fixing screw 121 fixes the crossbeam module 420 and the chassis 100 in the third direction. By fastening the crossbeam module 420 from different directions, the stability of the crossbeam module 420 in the chassis 100 can be further improved.

[0085] In some embodiments, referring also to Figures 12 to 14 , the server in this embodiment further includes a liquid collecting tray 700 and a liquid detection cable 800. The liquid collecting tray 700 is fixed to the side of the tray board 210 facing away from the bottom plate 110. Along the first direction, the liquid collecting tray 700 is located between the GPU board 300 and the crossbeam module 420, and the liquid collecting tray 700 is directly opposite to the part where the joint structure 330 on the GPU board 300 is connected to the pipeline 500. The liquid detection cable 800 is disposed in the liquid collecting tray 700 and is used to detect whether there is liquid in the liquid collecting tray 700. When the server is running normally, if the part where the joint structure 330 is connected to the pipeline 500 leaks liquid, the exposed liquid will fall into the liquid collecting tray 700 and will not directly fall onto the tray board 210 to cause a short circuit. At the same time, when the liquid detection cable 800 comes into contact with the liquid, an alarm can be triggered to remind the operator to cut off the cold plate liquid of the chassis 100 in time and maintain the chassis 100.

[0086] Referring to Figure 15 , the liquid collecting tray 700 may include a plurality of liquid collecting grooves 710. The plurality of liquid collecting grooves 710 are arranged in the third direction, and the plurality of liquid collecting grooves 710 can be correspondingly arranged one by one with the plurality of GPU boards 300 placed in the chassis 100. That is, each liquid collecting groove 710 is directly opposite to the joint structure 330 of one GPU board 300, and a liquid detection cable 800 is disposed in each liquid collecting groove 710 to facilitate accurate collection of the leaked liquid.

[0087] As an optional implementation, the shape of the liquid collecting groove 710 can be a funnel shape. At this time, the opening area of the liquid collecting groove 710 is larger than its bottom area, so that when the liquid falls into the liquid collecting groove 710, it can slowly flow along the side wall of the liquid collecting groove 710 into the bottom of the liquid collecting groove 710. Since the widths of different GPU boards 300 are different, it may cause the joint structure 330 on the GPU board 300 not to be directly opposite to the center of the liquid collecting groove 710. When the joint structure 330 is offset relative to the center of the liquid collecting groove 710, the liquid leaked from the joint structure 330 can also gradually flow along the inner wall of the liquid collecting groove 710 to the bottom of the liquid collecting groove 710. At this time, the liquid detection cable 800 is disposed at the bottom of the liquid collecting groove 710. Even if the amount of liquid falling into the liquid collecting groove 710 is very small, the liquid detection cable 800 can also accurately detect whether there is liquid in the liquid collecting groove 710, so as to accurately and effectively maintain the chassis 100.

[0088] refer to Figure 16 and Figure 17 When the effusion tray 700 is assembled with the tray board 210, the captive screws 720 can be used to fix the effusion tray 700 with the tray board 210. Specifically, the tray board 210 is provided with a second transfer hole, in which a second pressure rivet stud 212 is fixed, and the captive screws 720 are fixed in the second pressure rivet stud 212. It can be understood that when the effusion tray 700 needs to be taken out of the chassis 100 for maintenance, the captive screws 720 are removed from the second pressure rivet stud 212. At this time, the captive screws 720 cannot fall off the effusion tray 700. After the maintenance of the effusion tray 700 is completed, the captive screws 720 can be used to fix the effusion tray 700 with the tray board 210 again, thereby avoiding the situation where the effusion tray 700 is poorly fixed due to the use of wrong screws, and effectively shortening the maintenance time.

[0089] To prevent the liquid leaking from the joint structure 330 from leaking from the captive screw 720, Figure 16 As shown, a sealing rubber ring 730 is further provided between the captive screw 720 and the tray plate 210, and the sealing rubber ring 730 is located on the side of the tray plate 210 facing the liquid collection tray 700. When the captive screw 720 is fixed to the second pressure riveting stud 212, the sealing rubber ring 730 is squeezed by the tightening force of the screw, so that a good sealing effect can be achieved.

[0090] Or, refer to Figure 17 The liquid collection tray 700 is also provided with a retaining structure 740 surrounding the captive screw 720. The retaining structure 740 protrudes from the surface of the captive screw 720 on one side away from the tray board 210, so as to reduce the situation where liquid leaks into the tray board 210 and causes a short circuit.

[0091] In actual application, either the enclosure structure 740 or the sealing rubber ring 730 can be provided, or both can be provided, which is not limited in this embodiment.

[0092] In addition, the material of the liquid collection tray 700 can also be plastic. As a good insulating material, plastic can avoid contact with liquid and reaction, which affects the accuracy of the detection result of the liquid detection cable 800.

[0093] When assembling the server in the embodiment of the present utility model, for example, the board tray module 200 can be first installed in the chassis 100, then the crossbeam module 420 and the bracket 410 are installed in the chassis 100, then the liquid accumulation tray 700 is installed in the chassis 100, and finally the GPU board 300 is installed in the chassis 100. Or, for example, the crossbeam module 420, the bracket 410, and the liquid accumulation tray 700 can be first installed on the board tray module 200, then the board tray module 200 is installed in the chassis 100, and finally the GPU board 300 is installed in the chassis 100.

[0094] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
