Description

[0002] With the continuous iteration and upgrading of server products, better heat dissipation performance is needed to meet the continuous increase in CPU power and energy consumption.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to solve the problem in the prior art that when the liquid cooling pipelines of the liquid cooling server are plugged into the cabinet, the redundant liquid cooling pipelines need to be bundled and fixed by cable ties, resulting in cumbersome and complicated maintenance of the liquid cooling pipelines, the present invention provides a liquid cooling server.

[0034] like Figures 1 to 7 As shown, the liquid-cooling server includes a chassis, a mainboard 10, a liquid-cooling radiator 20 and a pipeline limiting assembly, wherein the chassis has a accommodating cavity; the mainboard 10 is arranged in the accommodating cavity; the liquid-cooling radiator 20 is arranged on the mainboard 10; in the direction from the front window to the rear window of the chassis, the pipeline limiting assembly sequentially includes a first limiting bracket 30, a second limiting bracket 40 and a third limiting bracket 50, wherein the first limiting bracket 30 is connected to the liquid-cooling radiator 20, and the first limiting bracket 30 has a limiting groove 321 for supporting the liquid cooling pipeline; the second limiting bracket 40 is arranged on the mainboard 10, and the second limiting bracket 40 has at least one guide limiting structure, which is used to constrain the liquid cooling pipeline to extend along a preset path; a part of the third limiting bracket 50 is connected to the mainboard 10, and another part of the third limiting bracket 50 is connected to the chassis, and the third limiting bracket 50 has two guide limiting holes 51 on the side away from the front window, and the two guide limiting holes 51 are respectively used to pass through the input pipe section and the output pipe section of the liquid cooling pipeline.

[0035] By configuring the pipeline limiting assembly to include a first limiting bracket 30, a second limiting bracket 40 and a third limiting bracket 50, it is ensured that the limiting groove 321 of the first limiting bracket 30 provides support and limiting reliability for the liquid cooling pipeline, and that the guiding limiting structure of the second limiting bracket 40 can layout the liquid cooling pipeline according to a preset path and reasonably utilize the space in the accommodating cavity, and that the two guiding limiting holes 51 of the third limiting bracket 50 can be used to pass through the input pipe section and the output pipe section of the liquid cooling pipeline respectively, thereby preventing the liquid cooling pipeline from shaking when the coolant is input and output, thereby ensuring the regularity and reliability of the layout of the liquid cooling pipeline.

[0036] It should be noted that the present application is mainly aimed at the situation where the server liquid cooling pipeline is plugged into the cabinet. The present application can adjust the length of the liquid cooling pipeline to adapt to different types of cabinets, and fix the liquid cooling radiator 20 and the liquid cooling pipeline in the accommodating cavity of the chassis. At the same time, it is also necessary to retain the floating amount of the liquid cooling pipeline adapted to different cabinets.

[0037] It should be noted that in the present application, there are at least two liquid cooling radiators 20, and at least two liquid cooling radiators 20 are arranged at intervals along the preset direction of the mainboard 10, and the two ends of the first limit bracket 30 are respectively movably connected to the two adjacent liquid cooling radiators 20, so that the distance between the two liquid cooling radiators 20 can be adjusted; wherein the preset direction is perpendicular to the direction from the front window to the rear window. In this way, it is conducive to fully utilizing the limited space on the mainboard 10.

[0038] like Figures 1 to 3 As shown, the first limiting bracket 30 includes a first bracket section 31, a support transition section 32 and a second bracket section 33, wherein the first end of the first bracket section 31 is movably connected to the first liquid-cooled radiator 20, and the second end of the first bracket section 31 is gradually raised in a direction away from the first liquid-cooled radiator 20; the first end of the support transition section 32 is smoothly connected to the second end of the first bracket section 31, and the second end of the support transition section 32 extends along a preset direction; the first end of the second bracket section 33 is movably connected to the second liquid-cooled radiator 20, and the second end of the second bracket section 33 is gradually raised in a direction away from the second liquid-cooled radiator 20, and is smoothly connected to the second end of the support transition section 32; wherein, in the extension direction from the first end of the support transition section 32 to its second end, part of the support transition section 32 extends toward one side of the mainboard 10 to form a limiting groove 321. In this way, by setting the first limiting bracket 30 to a structural form including a first bracket section 31, a support transition section 32 and a second bracket section 33, it is ensured that the raised support transition section 32 can avoid the components on the motherboard 10 and the remaining components in the accommodating cavity of the chassis. The setting of the limiting groove 321 plays an effective limiting and supporting role for the liquid cooling pipeline.

[0039] It should be noted that, in the present application, the height at which the second end of the first bracket segment 31 is raised is consistent with the height at which the second end of the second bracket segment 33 is raised. In this way, it is ensured that the bottom surface of the limiting groove 321 can be in a horizontal plane as much as possible, which is conducive to increasing the contact area between the groove wall surface and the bottom surface of the limiting groove 321 and the liquid cooling pipeline, thereby ensuring the reliability of the limiting support for the liquid cooling pipeline.

[0040] It should be noted that in the present application, the relative distance between the two liquid-cooling radiators 20 will be limited after the first limiting bracket 30 is added. The design can ensure that the distance between the two liquid-cooling radiators 20 is completely consistent with the distance between the CPUs. However, there are tolerances in actual processing, which makes it difficult to meet the requirements. Therefore, it is necessary to ensure that the installation distance between the CPUs can still be fine-tuned after the first limiting bracket 30 is installed. Therefore, the first sliding guide hole 311 and the first sliding guide nail 21 of the first limiting bracket 30 are optimized and designed. The first sliding guide hole 311 is set to a long waist-shaped hole to ensure the left and right movement of the liquid-cooling radiator 20. The size of the waist-shaped hole can be adjusted according to different processing capabilities, such as Figure 2 and Figure 3 As shown, a first sliding guide hole 311 is formed at the first end of the first bracket segment 31, and the first sliding guide hole 311 extends along a preset direction. A first sliding guide nail 21 is provided on the first liquid-cooling radiator 20, and the first sliding guide nail 21 is penetrated at the first sliding guide hole 311. At least before the first liquid-cooling radiator 20 is fixedly connected to the motherboard 10, the first sliding guide nail 21 is slidably matched with the first sliding guide hole 311. A second sliding guide hole 331 is formed at the first end of the second bracket segment 33, and the second sliding guide hole 331 extends along a preset direction. The second liquid-cooled radiator 20 has a second sliding guide pin 22, which is inserted into the second sliding guide hole 331. At least before the second liquid-cooled radiator 20 is fixedly connected to the motherboard 10, the second sliding guide pin 22 is slidably matched with the second sliding guide hole 331; the distance between the two liquid-cooled radiators 20 can be adjusted by slidingly matching the first sliding guide pin 21 with the first sliding guide hole 311, and by slidingly matching the second sliding guide pin 22 with the second sliding guide hole 331, so as to adapt to modules to be cooled with different spacing distances.

[0041] like Figures 1 to 3As shown, in this embodiment, two liquid-cooled radiators 20 are used as an example for explanation, there are two first sliding guide holes 311, the two first sliding guide holes 311 are arranged at intervals along a preset direction, there are two first sliding guide nails 21, the two first sliding guide nails 21 correspond one-to-one to the two first sliding guide holes 311; and / or, there are two second sliding guide holes 331, the two second sliding guide holes 331 are arranged at intervals along a preset direction, there are two second sliding guide nails 22, the two second sliding guide nails 22 correspond one-to-one to the two second sliding guide holes 331.

[0042] like Figure 4 As shown, the first sliding guide pin 21 has a first step structure, and the first step height of the first step structure is greater than the first bracket thickness of the first end of the first bracket segment 31, so that a first gap is set between the step surface of the first step structure and the surface of the first end of the first bracket segment 31, so that after the first liquid-cooling radiator 20 is fixedly connected to the motherboard 10, the first sliding guide pin 21 and the first sliding guide hole 311 can be fine-tuned; and / or, the second sliding guide pin 22 has a second step structure, and the second step height of the second step structure is greater than the second bracket thickness of the first end of the second bracket segment 33, so that a second gap is set between the step surface of the second step structure and the surface of the first end of the second bracket segment 33, so that after the second liquid-cooling radiator 20 is fixedly connected to the motherboard 10, the second sliding guide pin 22 and the second sliding guide hole 331 can be fine-tuned. In this way, Figure 4 The letter A in denoted the first gap, so that the first sliding guide pin 21 and the first sliding guide hole 311 can be fine-tuned. Of course, in the embodiment not shown in the figure, similarly, the second sliding guide pin 22 and the second sliding guide hole 331 can be fine-tuned.

[0043] Optionally, the first gap is 0.2 mm.

[0044] Optionally, the second gap is 0.2 mm.

[0045] like Figure 1 and Figure 5As shown, the second limiting bracket 40 includes a first support plate 41, which is detachably connected to the mainboard 10; the guiding limiting structure is a first wire buckle structure 42 arranged on the first support plate 41, and the setting position of the first wire buckle structure 42 is adjusted according to the extension direction of the liquid cooling pipeline; and / or, the guiding limiting structure is at least a guiding groove structure 43 formed on the first support plate 41. In this way, there can be multiple first wire buckle structures 42, and at least two of the multiple first wire buckle structures 42 have different directions, so as to ensure that the direction of the liquid cooling pipeline in different directions is controlled, which is more flexible and can flexibly adjust the position of each first wire buckle structure 42 according to the actual internal layout of the server; in addition, the guiding groove structure 43 can actually be a guiding groove structure 43 formed by the structural parts inside the server itself, or a guiding groove structure 43 protruding from the first support plate 41, which has the advantage of directly using the guiding groove structure 43 formed by the components inside the server, without adding new components to realize the constraint of the liquid cooling pipeline.

[0046] like Figure 6 and Figure 7 As shown, the third limiting bracket 50 includes a second support plate 52, a second wire buckle structure 53, a limiting boss 54 and a pressure plate structure 55, wherein the first end of the second support plate 52 is connected to the mainboard 10, and the second end of the second support plate 52 is connected to the chassis; the second wire buckle structure 53 is arranged at the first end of the second support plate 52; the limiting boss 54 is arranged at the second end of the second support plate 52, and the limiting boss 54 has two first arc-shaped grooves 541; the pressure plate structure 55 is covered on the limiting boss 54, and the pressure plate structure 55 has two second arc-shaped grooves 551, and the two second arc-shaped grooves 551 correspond to the two first arc-shaped grooves 541 one by one to respectively enclose two guide limiting holes 51, and the two guide limiting holes 51 are arranged at intervals along a preset direction. In this way, the setting of the second wire buckle structure 53 can ensure that the liquid cooling pipeline is routed along a preset direction and optimize the aesthetics of the liquid cooling pipeline. The setting of the pressure plate structure 55 ensures the reliability of the fixation of the liquid cooling pipeline and prevents the occurrence of messy liquid cooling pipelines or poor maintenance of the liquid cooling pipelines.

[0047] like Figure 6 and Figure 7As shown, the pressing plate structure 55 has a buckle 552, and the second support plate 52 has a limiting slot 521 at a position opposite to the buckle 552, and the buckle 552 is inserted into the limiting slot 521 to limit the pressing plate structure 55 on the second support plate 52; and / or, the pressing plate structure 55 has an assembly lug 553, the assembly lug 553 extends along the extension direction of the second support plate 52, and an assembly hole is provided on the assembly lug 553, and the third limiting bracket 50 also includes a hand screw 56, which passes through the assembly hole and is connected to the second support plate 52. In this way, it is ensured that the pressing plate structure 55 and the second support plate 52 can be detachably connected, and the disassembly and assembly between the two can be convenient.

[0048] It should be noted that in the present application, the first arc-shaped groove 541 and the second arc-shaped groove 551 are both rubber tube grooves, which use the elasticity of the rubber itself to fix the liquid cooling pipeline, and due to the existence of elasticity, the tube length can also be extended or shortened in real time.

[0049] The technical solution of the present invention is applied to provide a liquid cooling server, including a chassis, a mainboard 10, a liquid cooling radiator 20 and a pipeline limiting assembly, wherein the chassis has a receiving cavity; the mainboard 10 is arranged in the receiving cavity; the liquid cooling radiator 20 is arranged on the mainboard 10; in the direction from the front window to the rear window of the chassis, the pipeline limiting assembly sequentially includes a first limiting bracket 30, a second limiting bracket 40 and a third limiting bracket 50, wherein the first limiting bracket 30 is connected to the liquid cooling radiator 20, and the first limiting bracket 30 has a liquid limiting bracket 50. A limiting groove 321 is provided for supporting the liquid cooling pipeline; a second limiting bracket 40 is arranged on the mainboard 10, and the second limiting bracket 40 has at least one guide limiting structure, and the guide limiting structure is used to constrain the liquid cooling pipeline to extend along a preset path; a part of the third limiting bracket 50 is connected to the mainboard 10, and another part of the third limiting bracket 50 is connected to the chassis, and the third limiting bracket 50 has two guide limiting holes 51 on the side away from the front window, and the two guide limiting holes 51 are respectively used to pass the input pipe section and the output pipe section of the liquid cooling pipeline.

[0050] By configuring the pipeline limiting assembly to include a first limiting bracket 30, a second limiting bracket 40 and a third limiting bracket 50, it is ensured that the limiting groove 321 of the first limiting bracket 30 provides support and limiting reliability for the liquid cooling pipeline, and that the guiding limiting structure of the second limiting bracket 40 can layout the liquid cooling pipeline according to a preset path and reasonably utilize the space in the accommodating cavity, and that the two guiding limiting holes 51 of the third limiting bracket 50 can be used to pass through the input pipe section and the output pipe section of the liquid cooling pipeline respectively, thereby preventing the liquid cooling pipeline from shaking when the coolant is input and output, thereby ensuring the regularity and reliability of the layout of the liquid cooling pipeline.
