Description

Technical Field

[0001] The utility model belongs to the technical field of blind plug connectors, in particular to an asynchronous floating mechanism of a double-tube blind plug connector and a cabinet type liquid cooling server. Background Art

[0002] With the explosive growth of data volume, a large amount of computing power needs to be supported by servers. This background has further promoted the increase in the power consumption of the server as a whole, and the heat generation has further increased, making it increasingly difficult for conventional air cooling to meet the heat dissipation needs of the entire machine. In this context, liquid-cooled servers came into being. Liquid-cooled servers are a heat dissipation technology that uses liquid cooling to reduce the temperature of the server. The liquid medium can directly or indirectly contact the heat dissipation components to effectively absorb and remove the generated heat.

[0003] Common liquid-cooled servers mainly use cold plate liquid cooling to dissipate heat. The cold plate contacts the CPU and other heat-generating parts, and the water inlet and outlet joints are designed on the rear window of the chassis to connect to the water supply system on the rear side of the cabinet. Common joints are quick-connect joints and blind-connect joints. Quick-connect joints have a locking structure and flexible layout, but they need to be manually installed and unlocked at the rear of the cabinet during maintenance, which is cumbersome to operate. Blind-connect joints have the characteristics of being directly plugged in and having no locking structure. The blind-connect joints can be disassembled and assembled by designing fixed structures on the front window of the chassis and the front side of the cabinet, which is easy to maintain. However, since the blind-connect joints at the chassis and cabinet ends are fixed in position, the two joints (male and female) cannot be aligned or the stroke is insufficient due to processing tolerances, resulting in ineffective conduction, which poses a risk of leakage. Ensuring effective conduction of blind-connect joints within the tolerance range is a pain point in the application of blind-connect joints. Utility Model Content

[0004] In order to solve the problem that the traditional blind plug connector cannot be effectively connected and thus there is a risk of leakage, the utility model provides an asynchronous floating mechanism of a double-tube blind plug connector and a cabinet-type liquid cooling server.

[0005] On the one hand, the utility model is realized by the following technical solutions:

[0006] An asynchronous floating mechanism of a double-tube blind plug joint comprises two fixed pipelines, two corresponding floating pipelines, two support seats capable of positioning and installing the two floating pipelines, a guide block and a mounting frame capable of fixed installation; the two support seats are respectively installed in cooperation with the left and right sides of the guide blocks for front and rear sliding; a guide hole is provided on the side of the guide block close to the fixed pipeline, and a guide pin capable of positioning and inserting with the guide hole is positioned and installed on the fixed pipeline; a mounting seat is radially floatingly installed on the mounting frame, and a support column capable of sliding through the support seat is connected to the mounting seat, and a spring capable of elastically supporting the support seat toward one side of the fixed pipeline is mounted on the support column; the corresponding floating pipeline is connected to the fixed pipeline through a blind plug joint.

[0007] A further improvement of the utility model is that guide grooves are provided on both sides of the guide block, and guide rails capable of sliding and guiding with the guide grooves are provided on the support seat.

[0008] A further improvement of the utility model is that the mounting seat abuts against the surface of the mounting frame, and a radial adjustment hole is opened on the mounting frame. A fixing bolt that can pass through the radial adjustment hole and be screwed and installed with the mounting seat is provided on the side of the mounting frame away from the mounting seat, and the fixing bolt can be radially adjusted in the radial adjustment hole.

[0009] A further improvement of the utility model is that a boss is provided at the root of the screw rod of the fixing bolt, and the diameter of the boss is smaller than the diameter of the radial adjustment hole.

[0010] A further improvement of the utility model is that a washer is provided on a side of the fixing bolt and the mounting bracket away from the mounting seat.

[0011] A further improvement of the utility model is that a locking screw capable of being screwed and limited with the end of the support column is provided on one side of the support seat away from the mounting seat.

[0012] A further improvement of the utility model is that a positioning sleeve is sleeved on the floating pipeline; and a positioning sleeve installation hole for positioning and installing the positioning sleeve is opened on the support seat.

[0013] A further improvement of the utility model is that a plug post is provided on one side of the guide block close to the mounting frame, and a plug post limiting hole is provided on the mounting frame; the plug post can move radially in the plug post limiting hole.

[0014] A further improvement of the utility model is that one end of the guide hole close to the guide pin is chamfered.

[0015] Another aspect of the utility model is achieved through the following technical solutions:

[0016] A cabinet-type liquid cooling server comprises the asynchronous floating mechanism of the double-tube blind plug connector; the fixed pipeline is a cabinet-side pipeline fixed on the cabinet, and the floating pipeline is a server liquid cooling inlet and outlet pipeline; the mounting frame is fixedly mounted on the server chassis.

[0017] It can be seen from the above technical solutions that the beneficial effects of the utility model are:

[0018] When the floating pipeline and the fixed pipeline are plugged together through the blind plug joint, the guide hole on the guide block guides the guide pin, so that the mounting seat (together with the support column, guide block, and support seat) can be radially floated and adjusted on the mounting frame, thereby realizing radial alignment of the floating pipeline and the fixed pipeline, and ensuring the accuracy of the blind plug joint plugging; continue to push the floating pipeline backward, and the spring on the support column elastically supports the support seat (floating pipeline), which can ensure that the blind plug joint plugs fully and thoroughly, and avoid the situation of mis-plugging; and the two support seats are respectively installed with the two sides of the guide block for sliding forward and backward, which can realize the axial asynchronous floating adjustment of the two floating pipelines, and avoid the situation of mis-plugging the blind plug joint on one side. The overall structure is simple, easy to use, and practical, and can realize the radial floating adjustment and axial floating adjustment of the blind plug joint, which can effectively solve the mismatch problem caused by processing tolerance and assembly factors during the plug-in process of the blind plug joint.

DETAILED DESCRIPTION

[0026] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0027] like Figure 1-5 As shown, the utility model discloses an asynchronous floating mechanism of a double-tube blind plug joint, comprising two fixed pipelines arranged at the rear, two corresponding floating pipelines, two support seats 7 capable of positioning and installing the two floating pipelines, a guide block 8 and a mounting frame 9 capable of fixed installation; the mounting frame 9 is arranged on the side (front) of the support seat 7 away from the fixed pipeline, and the two support seats 7 are respectively slidably installed with the left and right sides of the guide block 8 forward and backward; two guide holes 81 are provided on the side of the guide block 8 close to the fixed pipeline, a mounting plate is connected and installed between the two fixed pipelines, and two guide pins 5 capable of positioning and inserting with the guide holes 81 are positioned and installed on the mounting plate; a mounting seat 10 is radially and floatingly installed on the mounting frame 9, and a support column 11 capable of sliding backward and penetrating the support seat 7 is connected to the mounting seat 10, a support column positioning hole 72 capable of slidingly guiding the support column 11 is provided on the support seat 7, and a spring 12 capable of elastically supporting the support seat 7 toward one side of the fixed pipeline (backward) is sleeved on the support column 11; the corresponding floating pipeline is connected to the fixed pipeline through the blind plug joint 3.

[0028] When the floating pipeline and the fixed pipeline are plugged in through the blind plug connector 3, the guide hole 81 on the guide block 8 guides the guide pin 5, so that the mounting seat 10 (together with the support column 11, the guide block 8, and the support seat 7) can be radially floated and adjusted on the mounting frame 9, so that the floating pipeline and the fixed pipeline can be radially aligned, and the accuracy of the plugging of the blind plug connector 3 can be ensured; the floating pipeline is pushed backward, and the spring 12 on the support column 11 elastically supports the support seat 7 (floating pipeline), which can ensure that the plugging of the blind plug connector 3 is sufficient and thorough, and the plugging is not in place; and the two support seats 7 are respectively installed with the two sides of the guide block 8 to slide forward and backward, so that the axial asynchronous floating adjustment of the two floating pipelines can be realized, and the blind plug connector 3 on one side can be not plugged in. The overall structure is simple, easy to use, and practical. It can realize 360-degree radial floating adjustment and axial floating adjustment of the blind plug connector 3, and can effectively solve the mismatching problem caused by processing tolerance and assembly factors during the plugging process of the blind plug connector 3.

[0029] Among them, Figure 2 , 5As shown, guide grooves 82 are provided on both sides of the guide block 8, and guide rails 71 capable of sliding and guiding with the guide grooves 82 are provided on the support seat 7. Asynchronous and precise guiding of both sides of the guide block 8 and the two support seats 7 can be achieved, ensuring the reliability of axial adjustment;

[0030] Furthermore, the guide groove 82 is connected to the side (front side) of the mounting frame 9, but not to the side (rear side) of the fixed pipeline. The side (rear side) of the support seat 7 away from the mounting seat 10 is provided with a locking screw 13 that can be screwed and limited with the end of the support column 11. The support seat 7 can be effectively limited in the forward direction, and the guide rail 71 and the guide groove 82 can be effectively prevented from falling out, ensuring the convenience and reliability of use.

[0031] The front side of the mounting seat 10 abuts against the rear surface of the mounting frame 9, and a radial adjustment hole 91 is provided on the mounting frame 9. A fixing bolt 14 that can pass through the radial adjustment hole 91 and be screwed and installed with the mounting seat 10 is provided on the side (front side) of the mounting frame 9 away from the mounting seat 10, and the fixing bolt 14 can be radially adjusted in the radial adjustment hole 91. The mounting seat 10 is connected and installed by the fixing bolt 14, and the fixing bolt 14 moves radially in the radial adjustment hole 91, so that the floating pipeline can be flexibly adjusted radially, and the radial adjustment range of the fixing bolt 14 can be limited by the radial adjustment hole 91.

[0032] Further, such as Figure 2 As shown, a boss 16 is provided at the root of the screw of the fixing bolt 14, and the diameter of the boss 16 is smaller than the diameter of the radial adjustment hole 91. The diameter of the boss 16 is larger than the diameter of the screw of the fixing bolt 14, and the boss 16 is radially adjusted and limited by the radial adjustment hole 91 to avoid wear on the thread of the screw.

[0033] Further, such as Figure 2 As shown, a washer 15 is provided on the side (rear side) of the fixing bolt 14 and the mounting frame 9 away from the mounting seat 10. The washer 15 is a rubber ring or a friction plate, and the washer 15 is pressed between the fixing bolt 14 and the mounting frame 9, which can effectively realize the suspension of the fixing bolt 14 (floating pipeline) at any position, reducing the lateral pulling on the floating pipeline.

[0034] Among them, Figure 2-3 As shown, a positioning sleeve 6 is mounted on the floating pipeline, and a positioning sleeve mounting hole 73 is provided on the support seat 7 to position and install the positioning sleeve 6. The floating pipeline is positioned and installed through the positioning sleeve 6 and the positioning sleeve mounting hole 73 on the support seat 7, ensuring the reliability and convenience of the positioning and installation of the floating pipeline and the support seat 7.

[0035] like Figure 2-5As shown, two plug posts 83 are provided on one side (front side) of the guide block 8 close to the mounting frame 9, and a plug post limiting hole 92 is opened on the mounting frame 9; the plug post 83 can move radially in the plug post limiting hole 92, and the plug post limiting hole 92 can limit the radial movement range of the plug post 83.

[0036] Furthermore, the mounting frame 9 is provided with a pipeline limiting hole 93 for the floating pipeline to pass through, and the pipeline limiting hole 93 can be freely adjusted and moved radially within the pipeline limiting hole 93 .

[0037] Among them, one end of the guide hole 81 close to the guide pin 5 is chamfered, which plays a guiding role and realizes the accurate alignment of the floating pipeline and the fixed pipeline.

[0038] like Figure 1 As shown, the utility model also discloses a cabinet-type liquid-cooled server, including the asynchronous floating mechanism of the double-tube blind plug connector; the fixed pipeline is a cabinet-side pipeline 2 fixed on the cabinet, and the floating pipeline is a server liquid cooling inlet and outlet pipeline 4; the mounting frame 9 is an L-shaped bending structure and is fixedly installed on the server chassis 1.

[0039] When the server chassis 1 is pushed into the cabinet for installation, the guide hole 81 on the guide block 8 guides the guide pin 5, so that the mounting seat 10 (together with the support column 11, the guide block 8, and the support seat 7) is radially floated and adjusted on the mounting frame 9, so that the radial alignment of the server liquid cooling inlet and outlet pipeline 4 and the cabinet side pipeline 2 can be achieved, and the accuracy of the blind plug connector 3 can be ensured; the server chassis 1 is pushed backward, and the spring 12 on the support column 11 elastically supports the support seat 7 (server liquid cooling inlet and outlet pipeline 4), which can ensure that the blind plug connector 3 is fully and thoroughly plugged in, and avoid the situation of incomplete plugging; and the two support seats 7 are respectively installed with the two sides of the guide block 8 forward and backward sliding, which can achieve axial asynchronous floating adjustment of the server liquid cooling inlet and outlet pipeline 4, and avoid the situation of incomplete plugging of the blind plug connector 3 on one side. Finally, the front window of the server chassis 1 is locked with the cabinet. The overall structure is simple, easy to use, and practical. It can realize 360-degree radial floating adjustment and axial floating adjustment of the blind plug connector 3, and can effectively solve the mismatch problem caused by processing tolerance and assembly factors during the plug-in process of the blind plug connector 3.

[0040] In the asynchronous floating mechanism of the double-tube blind plug connector and the cabinet-type liquid cooling server, when the floating pipeline and the fixed pipeline are plugged in through the blind plug connector 3, the guide hole 81 on the guide block 8 acts on the guide pin 5, so that the mounting seat 10 (together with the support column 11, the guide block 8, and the support seat 7) is radially floated and adjusted on the mounting frame 9, thereby realizing radial alignment of the floating pipeline and the fixed pipeline, and ensuring the accuracy of the plugging of the blind plug connector 3; the floating pipeline is continuously pushed backward, and the spring 12 on the support column 11 elastically supports the support seat 7 (floating pipeline), so that the blind plug connector 3 can be fully and thoroughly plugged in, and the situation of mis-plugging can be avoided; and the two support seats 7 are respectively installed on both sides of the guide block 8 for forward and backward sliding, so that the axial asynchronous floating adjustment of the two floating pipelines can be realized, and the situation of mis-plugging of the blind plug connector 3 on one side can be avoided. The overall structure is simple, easy to use, and practical. It can realize 360-degree radial floating adjustment and axial floating adjustment of the blind plug connector 3, and can effectively solve the mismatch problem caused by processing tolerance and assembly factors during the plug-in process of the blind plug connector 3.
