Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling equipment, in particular to an offset self-centering plug for a liquid cooling equipment. Background Art

[0002] With the accelerating advancement of global digital transformation, computer computing power has been integrated into various scenarios in production and life. Whether it is the research and development of high-end technology projects or the operation of daily shopping software, powerful computing power support is required. As the physical carrier of computing power, the data center provides support and guarantee for data transmission, information exchange, data processing and analysis, etc. by centrally storing, processing and managing data, and is a key information infrastructure related to the development of industrial digitization and intelligence.

[0003] Due to running day and night, large data centers store and transfer a huge amount of data. Thus, the most intuitive problem is the serious physical heat generation problem. Components such as motherboards, control centers, and hard disks generate a large amount of heat during high-speed operation. After mutual superposition, the temperature of the entire data center continues to rise, and efficient cooling and control are urgently needed. Compared with traditional air cooling, the specific heat capacity of liquid is thousands of times higher, and the heat dissipation efficiency is greatly improved. With its outstanding advantages of energy conservation and carbon reduction in refrigeration and heat dissipation, liquid cooling technology has gradually become the mainstream solution for data center cooling.

[0004] Relative to air cooling which only requires pushing without storage, liquid cooling technology needs to establish liquid cooling circulation equipment and conveying pipelines to transport the coolant to the heat-generating components, and also needs to circulate the heated coolant back for cooling and then put it into a new round of use. Therefore, data centers need to be equipped with liquid cooling conveying equipment, and the components used in the processes of storage, pumping, cooling, and circulation of liquid cooling equipment need to be connected through pipelines and connectors provided on the pipelines to form a complete liquid cooling equipment system.

[0005] During the connection process of the liquid cooling cabinet application device, the coolant of each chassis unit needs to be transported through a water collector. Appropriate specifications of plug connectors and matching socket connectors will be selected in the connection process of the chassis unit. The plug connector is directly inserted into the socket connector to achieve the connection and conduction of the liquid cooling equipment pipeline.

[0006] In order to assemble and plug in under pressure, existing plug connectors often require the connector to be accurately inserted into the socket. There are also plugging devices that have proposed a design for blind plugging and automatic guiding and sliding. For example, in a blind plug connector and a liquid cooling device in Patent CN202222067941.X, a floating bracket is provided inside the plug connector. The floating bracket is installed on the fixed plate through a floating component. The floating component includes a protrusion and a floating hole. The diameter of the floating hole is larger than that of the protrusion. The protrusion is assembled in the floating hole and can move circumferentially in the floating hole. In this solution, the floating bracket can float circumferentially relative to the fixed plate, that is, the floating bracket can float relative to the fixed plate in a plane perpendicular to the insertion direction to absorb the tolerances of the device to be cooled in the plane perpendicular to the insertion direction and the tolerances between the blind plug connector and the device to be cooled. However, this adjustment of the insertion angle is only limited to floating in the plane of the insertion direction and can only absorb the tolerances of the device to be cooled in the plane perpendicular to the insertion direction. It cannot overcome the problem of the angular deviation of the plug in the insertion direction. Therefore, when the plug is inserted, a large impact force will be applied to the axial direction of the plug. Moreover, if it is an integrated socket strip, it will cause great resistance to the insertion process, increase the insertion difficulty, and is not convenient to use. Summary of the Invention

[0008] An angle-offset self-centering plug for a liquid cooling device according to the utility model includes a plug cup body, a cup body end cover, a docking movable tube, a sliding top core and a plug connector.

[0024] Please refer to the attached Figure 1 ~attached Figure 3 : As shown therein, a liquid-cooling device offset self-centering plug is provided, including a plug cup body 10, a cup body end cover 20, a docking movable tube 30, a sliding top core 40 and a plug connector 50. It is characterized in that the docking movable tube includes a front tube 31 and a rear seat 32. The docking movable tube 30 has its rear seat 32 disposed in the plug cup body 10, and the front tube 31 extends outside the plug cup body 10 and faces the socket to be connected; the plug connector 50 is connected to the rear seat 32 of the docking movable tube 30 by a thread and conducts the internal sealed liquid flow path. A spring seat 21 is sleeved on the plug connector 50 and is locked in the plug cup body 10 by the cup body end cover 20. A section of compression spring is disposed between the end face of the rear seat 32 and the inside of the spring seat 21, and this section of compression spring is the first compression spring 322; a concentric guiding conical surface 35 is provided between the inner wall of the plug cup body 10 and the mutually fitting surface of the rear seat 32 of the docking movable tube 30 disposed therein.

[0025] Please refer to the attached Figure 4 , which is the attached Figure 2The partial enlarged view at A mainly shows the concentric guiding conical surface 35 between the inner wall of the plug cup body 10 and the mating surface of the built-in rear seat 32. The outer surface of the rear seat actually includes two sections of connected outer surfaces. One section for mating with the plug cup body 10 is the guiding conical surface 35, which is a partial conical surface coaxial with the inner wall. And the part connecting the guiding conical surface 35 to the front tube 31 is the arc surface 36.

[0026] The plug involved in the present utility model, in terms of its main structure, is divided into two ends, namely the docking movable tube 30 and the plug joint 50. After the two sections are docked, it substantially connects the coolant circulation pipeline. The plug cup body and the cup body end cover part are the outer shell frame parts, providing a support for the docking movable tube and a seat part for accommodating its offset and deflection.

[0027] The first compression spring 322 is stuck in the rear seat of the plug cup body 10 against the docking movable tube, actually providing buffering for the received force and elastic force for resetting.

[0028] The cup body end cover 20 is screwed and assembled on the plug cup body 10 through threads.

[0029] A sliding rubber pad 60 is provided between the spring seat 21 and the cup body end cover 20. On the one hand, the sliding rubber pad is circumferentially limited by the spring seat 21 by the clamping post, and on the other hand, it is pressed to directly contact the cup body end cover 20, constructing a sliding fit between rubber and metal. The cup body end cover 20 is connected to the plug cup body 10 through threads, restricting the docking movable tube 30 and the spring seat 21 inside the plug cup body 10.

[0030] The compression spring at the end face of the rear seat and inside the spring seat 21 is the first compression spring 322. A sliding jack core 40 is movably clamped inside the front tube 31 and abuts against the inner wall of the front tube 31. The sliding jack core 40 is outwardly clamped at the opening end of the front tube 31 and inwardly clamped inside the second compression spring 34 and the front tube 31. A first sealing ring 41 is provided between the sliding jack core 40 and the inner wall of the front tube of the docking movable tube 30.

[0031] A first sealing ring 41 is provided between the sliding jack core 40 and the inner wall of the front tube 31. A sealing groove 42 is provided on the outer periphery of the sliding jack core 40, and the first sealing ring 41 is clamped in the sealing groove 42 and abuts against the inner wall of the front tube 21. The first sealing ring is mainly used to seal the sliding jack core 40 and the front tube 31. When the plug is withdrawn from the assembled socket, the sliding jack core 40 retracts and seals to prevent liquid leakage.

[0032] Inside the front tube 31, there is a spring sleeve 311 and a circlip 312. The spring sleeve 311 and the circlip 312 limit the second compression spring 34 inside the front tube 31 of the docking movable tube 30. The spring sleeve 311 is sleeved on the end of the second compression spring 34 and is pressed tightly by the circlip 312 inside the front tube 31 from the opening to the middle section.

[0033] On the end face of the rear seat 32 of the docking movable tube 30, there is a card slot 321. One end of the first compression spring 322 is clamped into the card slot 321 and the other end is clamped in the spring seat 21.

[0034] At the connection part between the plug connector 50 and the rear seat 32 of the docking movable tube 30, there is a second sealing ring 51. The second sealing ring 51 is pressed tightly by the end face of the plug connector 50 and abuts against the inner wall of the rear seat 32 of the docking movable tube 30.

[0035] When the plug is in a free state, the first compression spring 322 is compressed, and its elastic force will push the docking movable tube 30 in the direction of a greater distance, thereby driving the guiding conical surface 35 of the docking movable tube 30 to be flush with the conical surface of the plug cup 10, making the docking movable tube 30 concentric with the plug cup 10 and the axis of the docking movable tube perpendicular to the end face of the plug cup. When the front tube of the docking movable tube 30 is radially stressed, the docking movable tube 30 can enter a deflection angle state. When the front tube of the docking movable tube 30 is axially stressed, the docking movable tube can enter a floating state. When the middle part of the docking movable tube is stressed, the docking movable tube can enter a translation state with the axis parallel and offset. During the process of the docking movable tube being radially / axially stressed, the first compression spring 322 and the sliding rubber pad 60 will play a buffering role. When the stress state is released, driven by the elastic force of the first compression spring 322, the plug returns to the free state, and the docking movable tube 30 resets to a position where it is concentric with the plug cup and the axis of the docking movable tube is perpendicular to the end face of the plug cup.

[0036] During use: It is used in cooperation with a socket. The joint socket and the plug are respectively installed on the water collector and the chassis. When the plug is inserted into the socket, it can be buffered by force and automatically reset when pulled out of the socket.

[0037] An angle-offset self-centering plug applicable to liquid cooling equipment enables the plug to offset the angle by itself for avoidance during docking insertion, buffer the impact during insertion, and use the elastic force buffering structure for centering and automatic reset of angle offset, so that the angle and position can be adaptively adjusted again during the next insertion.

[0038] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model is disclosed as above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art, without departing from the scope of the technical solution of the present utility model, when making some changes or modifications using the above-disclosed technical content to equivalent embodiments of equivalent changes, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the present utility model shall fall within the scope of the technical solution of the present utility model.
