For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0030] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0031] An embodiment of the present application provides a liquid-cooled plug, and the liquid-cooled plug includes a first plugging mechanism 2 and a splash-proof mechanism 4. Among them, the first plugging mechanism 2 is used for plugging and mating with a second plugging mechanism 1; the splash-proof mechanism 4 is disposed on the first plugging mechanism 2, and the splash-proof mechanism 4 is provided with a receiving cavity 411 for temporarily storing splashing liquid; when the first plugging mechanism 2 and the second plugging mechanism 1 are in a plugged state, the receiving cavity 411 sleeves the plugged connection between the second plugging mechanism 1 and the first plugging mechanism 2, and one axial end of the receiving cavity 411 is hermetically connected to the outer side wall of the second plugging mechanism 1, and the other end is hermetically connected to the outer side wall of the first plugging mechanism 2.

[0032] The anti-splash mechanism 4 in this application can be set as a soft material part. During the assembly process, the soft material anti-splash mechanism 4 can better fit with the outer side walls of the second plugging mechanism 1 and the first plugging mechanism 2, facilitating the sealing between the anti-splash mechanism 4 and the outer side walls of the second plugging mechanism 1 and the first plugging mechanism 2. Additionally, the accommodation cavity 411 of the anti-splash mechanism 4 in this specific embodiment needs to be sleeved on the plugging connection between the second plugging mechanism 1 and the first plugging mechanism 2. By setting the anti-splash mechanism 4 as a soft material part, during the actual assembly process, the anti-splash mechanism 4 can be deformed to a certain extent according to actual needs, facilitating the assembly.

[0033] Of course, the anti-splash mechanism 4 in this application can also be set as a plastic material or a hard material part, which is specifically determined according to the actual situation and will not be elaborated here.

[0034] During the actual use process, one end of the first plugging mechanism 2 can be connected to the pipeline to be connected first, and the anti-splash mechanism 4 can be installed on the first plugging mechanism 2. During the plugging process, the other end of the first plugging mechanism 2 is plugged with the other end of the second plugging mechanism 1. After the plugging fit, one end of the anti-splash mechanism 4 is hermetically connected to the outer side wall of the second plugging mechanism 1, and the other end is hermetically connected to the outer side wall of the first plugging mechanism 2.

[0035] In this specific embodiment, the accommodation cavity 411 of the anti-splash mechanism 4 is sleeved on the plugging connection between the second plugging mechanism 1 and the first plugging mechanism 2. This sleeved setting method facilitates setting the anti-splash mechanism 4 as an integral structure. During the assembly process, there are no gaps in the circumferential direction of the accommodation cavity 411, which can effectively prevent the splashing liquid from leaking through the circumferential gaps of the accommodation cavity 411. Additionally, in this specific embodiment, one axial end of the accommodation cavity 411 is hermetically connected to the outer side wall of the second plugging mechanism 1, and the other end is hermetically connected to the outer side wall of the first plugging mechanism 2, which can effectively prevent the splashing liquid from leaking from both axial ends of the accommodation cavity 411. Therefore, the accommodation cavity 411 completely seals the plugging connection between the second plugging mechanism 1 and the first plugging mechanism 2 inside, effectively preventing the splashing liquid from leaking into the external environment.

[0036] In this specific embodiment, due to the provision of the anti-spill mechanism 4, and the anti-spill mechanism 4 is provided with a receiving cavity 411 for accommodating the spilled liquid, the receiving cavity 411 is sleeved on the insertion connection of the second insertion mechanism 1 and the first insertion mechanism 2, and one axial end of the receiving cavity 411 is hermetically connected to the outer side wall of the second insertion mechanism 1, and the other end is hermetically connected to the outer side wall of the first insertion mechanism 2; the receiving cavity 411 of the anti-spill mechanism 4 completely covers the insertion connection of the second insertion mechanism 1 and the first insertion mechanism 2, and the receiving cavity 411 is hermetically connected to the insertion connection of the second insertion mechanism 1 and the first insertion mechanism 2, which can effectively collect the spilled liquid and prevent the spilled liquid from leaking. Therefore, the technical problem of the coolant directly splashing into the external environment can be solved, and the technical effect of improving the safety of the liquid cooling system can be achieved.

[0037] In another specific embodiment, the anti-spill mechanism 4 includes an elastic cover body 41, a first sealing connection part 42, and a second sealing connection part 43; the elastic cover body 41 is a cylindrical structure, and a receiving cavity 411 and a liquid accumulation cavity 412 for communicating with the receiving cavity 411 are provided inside the elastic cover body 41; when the second insertion mechanism 1 and the first insertion mechanism 2 are in the inserted state, the liquid accumulation cavity 412 is located at the lower side of the receiving cavity 411; the spilled liquid flows into the liquid accumulation cavity 412 through the receiving cavity 411 under the action of gravity, and the liquid accumulation cavity 412 is provided with a diversion pipe 413 for discharging the liquid; the first sealing connection part 42 is provided at one axial end of the elastic cover body 41, and the first sealing connection part 42 is used for hermetically connecting with the second insertion mechanism 1; the second sealing connection part 43 is provided at the other axial end of the elastic cover body 41, and the second sealing connection part 43 is used for hermetically connecting with the first insertion mechanism 2.

[0038] During the actual use process, if liquid splashes during the insertion of the second insertion mechanism 1 and the first insertion mechanism 2, the spilled liquid is first collected in the sealing cavity, and the spilled liquid in the sealing cavity flows into the liquid accumulation cavity 412 under the action of gravity and is temporarily stored in the liquid accumulation cavity 412. When the spilled liquid in the liquid accumulation cavity 412 reaches a certain amount, the diversion pipe 413 can be controlled to open to discharge the spilled liquid in the liquid accumulation cavity 412. Of course, the diversion pipe 413 can also be connected to an external liquid collection box, and the spilled liquid in the liquid accumulation cavity 412 will flow out to the liquid collection box through the diversion pipe 413 in real time.

[0039] Such as Figure 8As shown, the radial dimensions of the first sealing connection portion 42 and the second sealing connection portion 43 are both smaller than the radial dimension of the sealing cavity. This setting method enables a certain gap between the insertion connection portion of the second insertion mechanism 1 and the first insertion mechanism 2 and the inner side wall of the sealing cavity, so that the space for collecting splashed liquid in the accommodation cavity 411 meets the requirements. In addition, the gap between the first sealing connection portion 42 and the outer side wall of the second insertion mechanism 1 can be minimized as much as possible, and the gap between the second sealing connection portion 43 and the outer side wall of the first insertion mechanism 2 can be minimized as much as possible to facilitate the realization of a sealed connection.

[0040] In this specific embodiment, the first sealing connection portion 42 and the outer side wall of the second insertion mechanism 1 can be sealed by means of insertion connection or by providing a sealing ring, etc.; the second sealing connection portion 43 and the outer side wall of the first insertion mechanism 2 can be sealed by means of insertion connection or by providing a sealing ring, etc., which is specifically determined according to the actual situation and will not be elaborated here.

[0041] In this specific embodiment, the partition structure of the accommodation cavity 411 and the liquid accumulation cavity 412, in cooperation with the action of gravity, enables the splashed liquid to flow quickly and directionally to the liquid accumulation cavity 412, avoiding the retention of liquid in the critical connection area. The active drainage design of the diversion pipe 413 further reduces the risk of liquid residue and reduces corrosion or cross-contamination; the first sealing connection portion 42 and the second sealing connection portion 43 form a double barrier to block the liquid overflow path from the source, which is especially suitable for high-pressure or high-flow scenarios and significantly improves the environmental cleanliness. In addition, the cylindrical elastic material not only provides deformation buffering to adapt to different-sized insertion components (tolerance compatibility), but also maintains structural stability during mechanical vibration or plugging and unplugging operations, reducing wear caused by rigid friction. The cylindrical structure forms a 360° protective barrier, which, in cooperation with the diversion system, instantaneously transfers dangerous liquids (such as corrosive media and high-temperature fluids) and reduces the risk of operator contact.

[0042] In a specific embodiment, the accommodation cavity 411 and the liquid accumulation cavity 412 are arranged in a stepped manner, and the liquid accumulation cavity 412 protrudes from the outer surface of the accommodation cavity 411.

[0043] During the use of the liquid-cooled plug provided in this specific embodiment, the liquid splashed during the mating process of the second insertion mechanism 1 and the first insertion mechanism 2 will first be received in the accommodation cavity 411. Since the liquid accumulation cavity 412 is located below the accommodation cavity 411, under the action of gravity, the splashed liquid in the accommodation cavity 411 will flow to the liquid accumulation cavity 412; and the liquid accumulation cavity 412 protrudes from the outer surface of the accommodation cavity 411, which is convenient for collecting the splashed liquid and avoiding the long-term retention of the splashed liquid in the accommodation cavity 411.

[0044] In this specific embodiment, the stepped drop forms a liquid level potential energy difference, enabling the splashed liquid droplets to quickly slide along the inclined plane after colliding with the inner wall of the elastic cover, facilitating the collection of the splashed liquid. Additionally, when the second plugging mechanism 1 is in a plugged state with the first plugging mechanism 2, the liquid accumulation cavity 412 is located below the accommodation cavity 411, facilitating the splashed liquid to flow into the liquid accumulation cavity 412 by gravity without the need for external force, which can effectively simplify the structure of the liquid cooling plug and reduce costs.

[0045] In a specific embodiment, the second sealing connection portion 43 includes a tightening strap 432. The second sealing connection portion 43 is an elastic structure, and a plurality of threading holes 431 are provided along the circumferential direction of the second sealing connection portion 43. The tightening strap 432 is threaded through the threading holes 431 to tighten the second sealing connection portion 43.

[0046] During actual use, as Figure 9 shown, the tightening strap 432 is in a strip shape. During the threading process, the tightening strap 432 crosses through the threading holes 431 of the second sealing connection portion 43 to control the tightening of the second sealing connection portion 43 and ensure the sealing performance of the device.

[0047] In this specific embodiment, the second sealing connection portion 43 is tightened by the tightening strap 432 to be in sealing fit with the outer wall of the first plugging mechanism 2. Since the second sealing connection portion 43 has a certain elasticity, it can be applicable to the first plugging mechanism 2 with different radial dimensions. Additionally, both ends of the elastic cover body 41 are hermetically connected to the second plugging mechanism 1 and the first plugging mechanism 2 through the first sealing connection portion 42 and the second sealing connection portion 43 respectively, forming a protective barrier at the plugging connection of the anti-splash mechanism 4 with the second plugging mechanism 1 and the first plugging mechanism 2 to prevent the splashed liquid from leaking into the external environment.

[0048] During actual use, since the plugging connection between the second plugging mechanism 1 and the first plugging mechanism 2 is prone to liquid leakage during long-term use, in order to avoid the impact of liquid leakage on the normal operation of the device and avoid liquid waste, a liquid leakage alarm can be further included. A liquid leakage detection component is arranged inside the elastic cover body 41, and the liquid leakage detection component is connected to the liquid leakage alarm. When the liquid leakage information detected by the liquid leakage detection component is greater than a preset liquid leakage value, the liquid leakage alarm emits a warning message.

[0049] It should be noted that the liquid leakage detection component in this specific embodiment can be set as a liquid leakage detection patch, or can be set as a liquid level detection structure, or can be set as other liquid leakage detection structures that meet the requirements, which is specifically determined according to the actual situation and will not be elaborated here.

[0050] During actual use, when the liquid leakage detection component is a liquid leakage detection patch, the liquid leakage detection patch can be attached to the inner side wall of the elastic cover body 41. In the initial stage of the insertion fit between the second insertion mechanism 1 and the first insertion mechanism 2, there may be splashing liquid. At this time, the liquid leakage information detected by the liquid leakage detection component is the splashing information of the splashing liquid. After the insertion fit between the second insertion mechanism 1 and the first insertion mechanism 2 is completed, the liquid leakage detection component will detect the liquid leakage information in the elastic cover body 41 in real time. Specifically, the liquid leakage information can be the liquid level information of the leaked liquid in the liquid accumulation cavity 412. When it is found that the liquid level information in the liquid accumulation cavity 412 has increased, it indicates that there is a liquid leakage phenomenon at the insertion connection of the second insertion mechanism 1 and the first insertion mechanism 2. At this time, the liquid leakage alarm can be controlled to send out a warning message to notify the staff of the liquid leakage information in a timely manner. Or, if the slight liquid leakage does not affect the normal operation of the device, the liquid leakage amount at the insertion connection of the second insertion mechanism 1 and the first insertion mechanism 2 can be monitored through the liquid leakage information. When the liquid leakage information shows that the liquid leakage amount at the insertion connection of the second insertion mechanism 1 and the first insertion mechanism 2 is greater than the preset liquid leakage value per unit time, the liquid leakage alarm is controlled to send out a warning message to notify the staff of the liquid leakage information in a timely manner. When the liquid leakage information shows that the liquid leakage amount at the insertion connection of the second insertion mechanism 1 and the first insertion mechanism 2 is less than the preset liquid leakage value per unit time, the relevant situation is continuously observed and no warning message is sent for the time being.

[0051] Of course, the liquid leakage detection component in this specific embodiment can also be arranged at the insertion connection of the second insertion mechanism 1 and the first insertion mechanism 2, which is specifically determined according to the actual situation and will not be elaborated here.

[0052] The liquid leakage alarm in this specific embodiment can be set as a buzzer or a warning light. The liquid leakage alarm can be installed on the outer wall of the liquid cooling plug, or the liquid leakage alarm can be connected to an external control device so that the staff can obtain the liquid leakage information in a timely manner during remote control.

[0053] In this specific embodiment, by setting the liquid leakage detection component and the liquid leakage alarm, during actual use, when there is a liquid leakage phenomenon at the insertion connection of the second insertion mechanism 1 and the first insertion mechanism 2, the liquid leakage information at the insertion connection of the second insertion mechanism 1 and the first insertion mechanism 2 can be obtained in a timely manner, which is convenient for the staff to make timely responses and avoid increasing costs or affecting the normal operation of the device due to liquid leakage.

[0054] In a specific embodiment, the liquid cooling plug further includes a pressure balancing mechanism 5 disposed in the first plugging mechanism 2. The pressure balancing mechanism 5 is provided with a pressure balancing chamber 5212 for communicating with the liquid flow channel in the first plugging mechanism 2. When the pressure in the liquid flow channel is greater than a preset pressure value, the pressure balancing chamber 5212 is in an open state to release the pressure; when the pressure in the liquid flow channel is less than the preset pressure value, the pressure balancing chamber 5212 is in a closed state.

[0055] During actual use, when the pressure in the liquid flow channel is greater than the preset pressure value, the pressure balancing chamber 5212 is in an open state to release the pressure, and the excess pressure is released through a bypass or a pressure relief port to prevent damage to the pipeline or the seal; when the pressure in the liquid flow channel is less than the preset pressure value, the pressure balancing chamber 5212 is in a closed state, and the fluid flows along the designed flow channel without affecting the normal operation of the system.

[0056] The pressure balancing mechanism 5 in this specific embodiment significantly improves the safety, reliability and economy of the liquid cooling plug through the two-way adjustment of automatic pressure relief and low-pressure protection, and is particularly suitable for industrial systems with frequent pressure fluctuations or strict requirements for seal integrity. Its adaptive mechanism and modular design make it a key safety component in complex fluid control scenarios; in addition, the design of the pressure balancing mechanism 5 is simple and effective, solving the problems of coolant splashing, leakage and even pipeline explosion caused by excessive internal pressure in the liquid cooling pipeline, increasing the operating stability of the liquid cooling system, and thus improving the working performance of the server.

[0057] On the basis of the above embodiment, the pressure balancing mechanism 5 can include a connection body 51 and a pressure control component 52. Among them, the connection body 51 is disposed in the second plugging mechanism 1 or the first plugging mechanism 2; the connection body 51 is provided with a first ventilation hole 511 for communicating with the liquid flow channels in the second plugging mechanism 1 and the first plugging mechanism 2; the pressure control component 52 is disposed on the connection body 51. The pressure control component 52 includes a pressure control body 521, a pressure valve 522, an elastic member 523 and a limiting structure 5211 disposed on the pressure control body 521. The pressure control body 521 is provided with a pressure balancing chamber 5212, and the pressure balancing chamber 5212 communicates with the first ventilation hole 511. The pressure valve 522 is located in the pressure balancing chamber 5212. One end of the elastic member 523 abuts against the pressure valve 522, and the other end abuts against the limiting structure 5211.

[0058] When the pressure in the liquid flow channel is greater than the preset pressure value, the pressure valve 522 moves away from the first ventilation hole 511 under the action of the pressure, overcoming the elastic force of the elastic member 523, so as to open the first ventilation hole 511; when the pressure in the liquid flow channel is less than the preset pressure value, the pressure valve 522 blocks the first ventilation hole 511 under the elastic force of the elastic member 523.

[0059] In this specific embodiment, the connection body 51 is mainly used to install and fix the pressure control component 52. Meanwhile, a second ventilation hole 215 is provided to connect the pressure balance cavity 5212 with the liquid flow channels in the second plugging mechanism 1 and the first plugging mechanism 2.

[0060] To prevent the liquid in the liquid flow channels from spraying out to the external environment through the pressure balance cavity 5212, a cover body for collecting the splashing liquid can be arranged outside the pressure control component 52, and a diversion structure is arranged on the cover body to guide and collect the splashing liquid in the cover body.

[0061] In this specific embodiment, by replacing different elastic members 523, the preset pressure value can be adjusted. Specifically, the elastic member 523 can be set as a spring.

[0062] The connection body 51 in this specific embodiment can be set as a Figure 12 ring-shaped structure as shown. As Figure 10 shown, the pressure control component 52 is arranged on the outer side wall of the connection body 51. As Figure 12 shown. An internal thread 512 is arranged on the inner side wall of the connection body 51, and the internal thread 512 is in fit connection with the second external thread 2121 of the pipe communication part 212 in the first plugging mechanism 2; the first ventilation hole 511 is arranged on the connection body 51 and penetrates through the thickness direction of the connection body 51.

[0063] As Figure 12 、 14 shown, the pressure control component 52 includes a pressure control main body 521 and a base 524. The pressure control main body 521 is provided with a pressure balance cavity 5212, a limiting structure 5211 and a positioning hole 5213. The base 524 is located at the top of the pressure control main body 521, and the base 524 includes a positioning convex part 5241, a spring limiting part 5242, an installation convex part 5243 and a base main body 5244; during the actual assembly process, the pressure valve 522 is located in the pressure balance cavity 5212. One end of the elastic member 523 abuts against the pressure valve 522, and the other end abuts against the base main body 5244. Moreover, the other end of the elastic member 523 is sleeved on the outer periphery of the installation convex part 5243 to realize the positioning of the elastic member 523. The limiting structures 5211 are arranged in a circumferential array, which can effectively prevent the elastic member 523 from being distorted and displaced after being pressed; the spring limiting parts 5242 are arranged in a circumferential array, and their functions are similar to those of the limiting structures 5211, which can also effectively prevent the elastic member 523 from being distorted and displaced after being pressed. The positioning hole 5213 in the pressure control main body 521 cooperates with the positioning convex part 5241 in the base 524, which can guide the installation of the base 524 and prevent installation errors. In addition, the top of the positioning convex part 5241 is chamfered, which is convenient for the alignment installation of the base 524 and the connection body 51 and ensures the coaxiality of the first ventilation hole 511.

[0064] In this specific embodiment, the pressure balance mechanism 5 significantly improves the pressure stability, operation safety, and maintenance convenience of the pipeline system through a modular structure, a dynamic pressure response mechanism, and a multiple safety guarantee design. The elastic member 523 sets the pressure threshold through a pre-tightening force, and the pressure valve 522 is in dynamic balance with the elastic force under the action of the fluid pressure. When the flow channel pressure exceeds the preset value, the pressure valve 522 compresses the elastic member 523 to open and release the pressure; when the pressure decreases, the elastic member 523 pushes the pressure valve 522 back to close, realizing adaptive pressure regulation. The limit structure 5211 limits the maximum displacement of the pressure valve 522 to prevent excessive pressure relief or structural damage caused by over-opening; when the elastic member 523 rebounds, the limit structure 5211 guides the pressure valve 522 to accurately reset, avoiding the leakage risk caused by the offset of the sealing surface. Through the core mechanism of elastic drive-limiting control, combined with compact integration, material adaptation, and modular maintenance design, the pressure balance mechanism 5 realizes precise pressure management, rapid and safe response, and long-term stable operation, becoming an indispensable pressure protection unit in complex fluid systems. Its technical advantages are particularly prominent under extreme working conditions such as high pressure, high frequency, and corrosion, significantly reducing the system failure rate and improving the comprehensive economic benefits.

[0065] On the basis of the above embodiment, the pressure valve 522 can include an end structure 5222 arranged in a stepped shape and a rod-shaped structure 5221 connected to the end structure 5222. One end of the rod-shaped structure 5221 far from the end structure 5222 is a hemispherical structure 5224, and the hemispherical structure 5224 is used to cooperate with the first vent hole 511 to block the first vent hole 511; an installation groove 5223 is arranged on the side of the end structure 5222 facing away from the rod-shaped structure 5221, and one end of the elastic member 523 is located in the installation groove 5223.

[0066] The top of the valve core is a hemispherical structure 5224, and the hemispherical structure 5224 cooperates with the first vent hole 511 of the connection body 51 and its radial dimension is larger than that of the first vent hole 511, ensuring that the pressure valve 522 is completely attached to the connection body 51 in the pressurized state to form an air pressure isolation effect. The rod-shaped structure 5221 is inserted into the connection body 51 to play a connecting role. The arrangement of the installation groove 5223 facilitates the installation of the elastic member 523.

[0067] Specifically, the elastic member 523 can be set as a spring.

[0068] In this specific embodiment, the pressure valve 522 significantly improves the sealing reliability, motion stability, and maintenance convenience through the collaborative design of the stepped end structure 5222, hemispherical sealing surface, and mounting groove 5223. The stepped design disperses the fluid pressure through different diameter levels, avoiding stress concentration and reducing the risk of deformation of the end structure 5222. The hemispherical structure 5224 forms a line contact or surface contact with the first vent hole 511 when closed. Even if there are minor alignment deviations or wear, the sealing integrity can still be maintained through the self - adaptability of the spherical surface. The mounting groove 5223 fixes the end of the elastic member 523, ensuring that the compression force is evenly transmitted along the valve stem axis and avoiding eccentric wear of the sealing surface caused by lateral component forces. The elastic member 523 and the pressure valve 522 are integrated into the pressure control main body 521. When damaged, they can be replaced as a whole without disassembling the flow channel or plug - in mechanism, reducing the downtime. The design of the pressure valve 522 in this specific embodiment realizes the comprehensive improvement of sealing performance, dynamic response, and durability through geometric optimization and material innovation, becoming an efficient and reliable pressure management unit in complex fluid systems. Its adaptive sealing mechanism and modular architecture are particularly suitable for industrial fields with strict requirements for safety, maintenance efficiency, and multi - working - condition compatibility.

[0069] In a specific embodiment, the liquid - cooled plug further includes a pressure alarm. The pressure control assembly 52 further includes a pressure sensor disposed in the pressure balance cavity 5212. The pressure sensor is connected to the pressure alarm and is used to detect the pressure information in the pressure balance cavity 5212. When the pressure information detected by the pressure sensor is greater than a preset warning pressure value, the pressure alarm emits a warning message.

[0070] During actual use, when the pressure in the pressure balance cavity 5212 is too high, there are certain safety hazards. Therefore, a pressure sensor is provided. When the pressure information detected by the pressure sensor is greater than the preset warning pressure value, the pressure alarm emits a warning message, enabling the staff to timely obtain the information that the pressure in the pressure balance cavity 5212 is too high and make emergency operations in a timely manner.

[0071] In this specific embodiment, by deeply coupling the pressure sensor, pressure alarm, and pressure balance mechanism 5, this design realizes the upgrade from passive pressure relief to active warning, significantly improving the safety, intelligent level, and operation and maintenance efficiency of the liquid - cooled plug. The pressure sensor is directly embedded in the pressure balance cavity 5212 to collect the intracavity pressure data in real - time, eliminating the monitoring delay caused by pipeline damping of traditional external sensors and responding to pressure fluctuations in milliseconds. Through the trinity coordination of sensing - alarm - pressure relief, the pressure management is upgraded from "passive response" to "active defense + intelligent decision - making", greatly reducing the probability of safety accidents and operation and maintenance costs, and at the same time providing a data foundation for process flow optimization.

[0072] Based on the above embodiments, the number of the pressure control components 52 can be set to be multiple, and the multiple pressure control components 52 are respectively arranged at different positions in the circumferential direction of the connection main body 51, and the preset pressure values of the pressure valves 522 in different pressure control components 52 are different.

[0073] During the actual use process, if only one pressure control component 52 is set, when the pressure in the pressure balance cavity 5212 is relatively large, the pressure relief efficiency of a single pressure control component 52 is relatively low, and it is easy to occur that the pressure in the pressure balance cavity 5212 is not relieved to meet the requirements for a long time; therefore, in this specific embodiment, multiple pressure balance cavities 5212 are provided, and the preset pressure values in the multiple pressure balance cavities 5212 are different. During the actual use process, when the pressure in the pressure balance cavity 5212 reaches the lowest preset pressure value among them, the pressure balance cavity 5212 of the corresponding pressure control component 52 is opened for pressure relief. When the pressure relief efficiency of a single pressure control component 52 does not meet the requirements and the pressure in the pressure balance cavity 5212 continues to increase, the next pressure control component 52 will be further opened, and the pressure balance cavity 5212 of the corresponding pressure control component 52 is opened, and the two pressure control components 52 perform pressure relief simultaneously; thus, when the pressure in the pressure balance cavity 5212 further increases, the pressure balance cavities 5212 of more pressure control components 52 will be in an open state to meet the pressure relief efficiency requirements.

[0074] In this specific embodiment, by distributing multiple pressure control components 52 along the circumferential direction of the connection main body 51 and setting different preset pressure values, this design realizes hierarchical pressure management, redundant safety protection and dynamic load balancing, and significantly improves the reliability, adaptability and maintenance efficiency of the system; the pressure valves 522 with different preset pressure values are triggered in sequence from low to high according to the threshold values. The low-pressure valve 522 preferentially releases slight overpressure, and the high-pressure valve 522 deals with extreme working conditions, avoiding the wear caused by the frequent opening and closing of a single valve body. When a certain pressure valve 522 is stuck or leaks, the remaining components can still respond normally, ensuring the continuous and safe operation of the system under partial faults. Through the multi-dimensional coordination of spatial distribution and pressure thresholds, the traditional passive pressure relief is upgraded to intelligent hierarchical pressure management. On the premise of ensuring system safety, the process continuity is maintained to the greatest extent, and the service life of key components is significantly extended.

[0075] The present application also provides a liquid-cooled plug-in device, including a second plugging mechanism, a sealing mechanism and the liquid-cooled plug as described in any one of the above; the first plugging mechanism 2 of the liquid-cooled plug is in plugging fit with the second plugging mechanism 1; the sealing mechanism 3 is sleeved on the outer side wall of the second plugging mechanism 1, and when the second plugging mechanism 1 and the first plugging mechanism 2 are in a plugged state, the inner ring of the sealing mechanism 3 is in sealing fit with the outer side wall of the second plugging mechanism 1, and the outer ring of the sealing mechanism 3 is in sealing fit with the inner side wall of the first plugging mechanism 2.

[0076] The sealing mechanism 3 in the present application may include multiple sealing mechanisms 3. During actual use, by arranging different sealing structures at different axial positions of the insertion connection between the second insertion mechanism 1 and the first insertion mechanism 2, multiple seals at the insertion connection between the second insertion mechanism 1 and the first insertion mechanism 2 can be achieved, improving the sealing effect.

[0077] During actual use, the sealing mechanism 3 can be first sleeved on the second insertion mechanism 1, and one end of the second insertion mechanism 1 is connected to the pipeline to be connected. When the second insertion mechanism 1 and the first insertion mechanism 2 are in an insertion fit state, the inner ring of the sealing mechanism 3 is in sealing fit with the outer side wall of the second insertion mechanism 1, and the outer ring of the sealing mechanism 3 is in sealing fit with the inner side wall of the first insertion mechanism 2.

[0078] Through this specific embodiment, since the inner ring of the sealing mechanism 3 is in sealing fit with the outer side wall of the second insertion mechanism 1, and the outer ring of the sealing mechanism 3 is in sealing fit with the inner side wall of the first insertion mechanism 2, effective sealing between the second insertion mechanism 1 and the first insertion mechanism 2 can be achieved. Therefore, the technical problem of imperfect sealing between the second insertion mechanism 1 and the first insertion mechanism 2 can be solved, and the technical effect of improving the sealing effect between the second insertion mechanism 1 and the first insertion mechanism 2 can be achieved.

[0079] On the basis of the above embodiments, in a specific embodiment, one of the anti-splash mechanism 4 and the second insertion mechanism 1 is provided with a sealing protrusion 421. The number of the sealing protrusions 421 is multiple, and the multiple sealing protrusions 421 are evenly distributed along the circumferential direction of the anti-splash mechanism 4; the other of the anti-splash mechanism 4 and the second insertion mechanism 1 is provided with a sealing groove 1121 that cooperates with the sealing protrusion 421.

[0080] Specifically, as Figure 8 shown, the sealing protrusion 421 can be arranged on the first sealing connection part 42.

[0081] As Figure 3 shown, a plurality of sealing grooves 1121 are arranged along the circumferential direction in the first plug body 11. As Figure 8 shown, a plurality of sealing protrusions 421 are arranged along the circumferential direction on the first sealing connection part 42. During actual use, through the mating snap connection between the sealing groove 1121 and the sealing protrusion 421, the sealing connection between the first plug body 11 and the first sealing connection part 42 is realized.

[0082] The sealing protrusion 421 in this specific embodiment can be set as a wedge-shaped block. During the process of the sealing groove 1121 and the sealing protrusion 421 being in snap fit, the inclined surface of the wedge-shaped block can play a certain guiding role, facilitating the sealing protrusion 421 to enter the sealing groove 1121.

[0083] The sealing protrusion 421 can be set as an elastic structure. During the process of the snap-fit between the sealing groove 1121 and the sealing protrusion 421, the sealing protrusion 421 undergoes a certain deformation, enabling the sealing groove 1121 and the sealing protrusion 421 to be tightly fitted, which is beneficial to improving the sealing effect between the second plugging mechanism 1 and the first sealing connection part 42.

[0084] In this specific embodiment, through the snap-fit between the sealing groove 1121 and the sealing protrusion 421, a sealed connection is achieved between the second plugging mechanism 1 and the first sealing connection part 42 of the anti-splash mechanism 4. Since in this specific embodiment, the sealing groove 1121 and the sealing protrusion 421 are axially relatively close to achieve the snap-fit, during the process of the plugging fit between the second plugging mechanism 1 and the first plugging mechanism 2, the snap-fit between the sealing groove 1121 and the sealing protrusion 421 can be synchronously achieved, and the operation process is convenient. In addition, a plurality of sealing protrusions 421 are arranged circumferentially. During actual use, the plurality of protrusions form a series sealing ring, which can effectively improve the sealing effect.

[0085] On the basis of the above embodiment, in order to facilitate the alignment of the sealing groove 1121 and the sealing protrusion 421 in the circumferential direction during the plugging fit between the second plugging mechanism 1 and the first plugging mechanism 2, one of the anti-splash mechanism 4 and the second plugging mechanism 1 can be provided with a guiding protrusion extending axially, and the other of the anti-splash mechanism 4 and the second plugging mechanism 1 can be provided with a guiding groove for cooperating with the guiding protrusion; when the guiding protrusion and the guiding groove are in a cooperating state, the sealing protrusion 421 and the sealing groove 1121 are disposed opposite to each other, and the liquid accumulation cavity 412 is located at the lower side of the accommodating cavity 411.

[0086] Specifically, during the process of the plugging fit between the second plugging mechanism 1 and the first plugging mechanism 2, the guiding protrusion is located in the guiding groove, and the guiding protrusion moves axially along the guiding groove. At this time, the sealing protrusion 421 and the sealing groove 1121 are disposed opposite to each other. When the second plugging mechanism 1 and the first plugging mechanism 2 move axially relative to each other to a preset position, the sealing protrusion 421 is just clamped in the sealing groove 1121, and when the second plugging mechanism 1 and the first plugging mechanism 2 are in a plugging fit state, the liquid accumulation cavity 412 is located at the lower side of the accommodating cavity 411, so that the splashing liquid in the accommodating cavity 411 can smoothly flow into the liquid accumulation cavity 412 under the action of gravity.

[0087] In this specific embodiment, by providing the guiding convex part and the guiding groove, the circumferential positioning of the second plugging mechanism 1 and the first plugging mechanism 2 during the plugging fit process can be realized, which is convenient for the circumferential alignment and cooperation of the sealing groove 1121 and the sealing protrusion 421, and is also convenient for restricting the circumferential position of the liquid accumulation cavity 412, so that the splashing liquid in the accommodating cavity 411 can smoothly flow into the liquid accumulation cavity 412 under the action of gravity.

[0088] In a specific embodiment, to avoid the situation where the second plugging mechanism 1 and the first plugging mechanism 2 are not plugged in place or the second plugging mechanism 1 and the first plugging mechanism 2 are over-plugged, a clamping convex part can be arranged on one of the second plugging mechanism 1 and the first plugging mechanism 2, and an elastic resetting part is arranged at the bottom of the clamping convex part; a clamping concave part for cooperating with the clamping convex part is arranged on the other. Specifically, the clamping convex part can be arranged on the outer side wall of the second plugging mechanism 1, and the clamping concave part can be arranged on the inner side wall of the first plugging mechanism 2. The first plugging mechanism 2 is sleeved outside the second plugging mechanism 1. The clamping convex part can be radially moved to a position flush with the outer side wall of the second plugging mechanism 1. When there is no external force, the clamping convex part extends to a position protruding from the outer side wall of the second plugging mechanism 1 under the elastic force of the elastic resetting part, so as to realize the clamping cooperation with the clamping concave part. In the actual use process, when the second plugging mechanism 1 and the first plugging mechanism 2 are plugged and matched, in the initial stage, the clamping convex part extends to a position protruding from the outer side wall of the second plugging mechanism 1 under the elastic force of the elastic resetting part. When the first plugging mechanism 2 moves to a position covering the clamping convex part, under the extrusion of the inner side wall of the first plugging mechanism 2, the clamping convex part is located at a position flush with the outer side wall of the second plugging mechanism 1. When the first plugging mechanism 2 and the second plugging mechanism 1 move to a position where the clamping concave part and the clamping convex part are matched during the plugging process, the clamping convex part extends to a position protruding from the outer side wall of the second plugging mechanism 1 under the elastic force of the elastic resetting part, so as to realize the clamping cooperation with the clamping concave part. During the process of the clamping convex part and the clamping concave part achieving the clamping cooperation, a prompting sound of the collision between the clamping convex part and the clamping concave part will be emitted, and the operator can timely obtain the information that the second plugging mechanism 1 and the first plugging mechanism 2 are plugged in place.

[0089] Alternatively, a in-place detection part can be arranged on one of the second plugging mechanism 1 and the first plugging mechanism 2, and an in-place convex part for cooperating with the in-place detection part is arranged on the other. When the second plugging mechanism 1 and the first plugging mechanism 2 are plugged in place, the in-place convex part contacts the in-place detection part, and the in-place detection part detects the in-place information. At this time, the in-place detection part emits an in-place signal. Specifically, it can be a sound warning signal or the flashing information of an in-place indicator light, which is specifically determined according to the actual situation. When the operator observes the in-place signal, the plugging operation of the second plugging mechanism 1 and the first plugging mechanism 2 can be stopped.

[0090] In this specific embodiment, by arranging the clamping convex part and the clamping concave part, the information that the second plugging mechanism 1 and the first plugging mechanism 2 are plugged in place can be obtained in time, and the situation where the second plugging mechanism 1 and the first plugging mechanism 2 are not plugged in place or over-plugged can be avoided. The in-place detection part and the in-place convex part can also be arranged. When the second plugging mechanism 1 and the first plugging mechanism 2 are plugged in place, the in-place information is emitted in time, making the plugging cooperation between the second plugging mechanism 1 and the first plugging mechanism 2 more convenient.

[0091] In a specific embodiment, the second plug-in mechanism 1 includes a first plug body 11, and the sealing mechanism 3 includes a first sealing ring 31 and a second sealing ring 32. An end of the first plug body 11 inserted into the first plug-in mechanism 2 is provided with a sealing groove 1111 for accommodating the first sealing ring 31, and the first sealing ring 31 is a stepped sealing ring; the second sealing ring 32 is sleeved on an end of the first plug body 11 facing away from the first plug-in mechanism 2.

[0092] like Figure 4 As shown, the first sealing ring 31 can be set as a stepped sealing ring, such as Figure 3 As shown, the first plug body 11 is provided with a sealing groove 1111 , and the first sealing ring 31 is clamped in the sealing groove 1111 .

[0093] The stepped seal ring has a stepped cross section, which can deform adaptively under pressure, fit tightly to the sealing surface, and form a multiple sealing barrier. This structure not only increases the contact area, but also evenly distributes the pressure and reduces local stress.

[0094] The second sealing ring 32 is sleeved on an end of the first plug body 11 away from the first plug mechanism 2. During actual use, the end of the first plug body 11 where the second sealing ring 32 is provided needs to be connected to the pipe. The second sealing ring 32 is provided at the connection between the pipe and the first plug body 11 to achieve sealing between the pipe and the first plug body 11.

[0095] In this specific embodiment, the number of first sealing rings 31 can be set to multiple, and multiple first sealing rings 31 are arranged at axial intervals on the first plug body 11. When the first plug-in mechanism 2 is sleeved on the first plug body 11, multiple first sealing rings 31 can achieve multiple sealing between the second plug-in mechanism 1 and the first plug-in mechanism 2, effectively improving the sealing effect.

[0096] By setting the first sealing ring 31, the sealing of the plug connection between the second plug-in mechanism 1 and the first plug-in mechanism 2 can be achieved, and setting the first sealing ring 31 as a stepped sealing ring can effectively improve the sealing effect; in addition, the setting of the second sealing ring 32 can achieve the sealing between the second plug-in mechanism 1 and the pipeline connected to it, and setting the second sealing ring 32 as an annular sealing ring can effectively prevent the liquid in the pipeline from splashing due to pressure fluctuations.

[0097] like Figure 3As shown, the first plug body 11 includes a first insertion portion 111, a first operation portion 112, and a first connection portion 113 arranged in sequence; the first insertion portion 111 is used for plugging and mating with the first plugging mechanism 2; the radial dimension of the first operation portion 112 is larger than that of the first insertion portion 111, and one side of the first operation portion 112 facing the first insertion portion 111 is hermetically connected to the splash-proof mechanism 4; the first connection portion 113 is provided with a first external thread 1131, and the second sealing ring 32 is sleeved on the first connection portion 113 and contacts the first operation portion 112.

[0098] During the actual setting process, a hexagonal wall surface can be provided on the outer circle of the first operation portion 112 to facilitate the operation of tools such as wrenches for screwing the first plug assembly; alternatively, a sealing groove 1121 can be provided on one side of the first operation portion 112 facing the first insertion portion 111. The sealing groove 1121 is used to cooperate with the sealing protrusion 421 in the splash-proof mechanism 4. When the second plugging mechanism 1 and the first plugging mechanism 2 are in a plugged and mated state, the sealing groove 1121 and the sealing protrusion 421 are snap-fitted. During the snap-fitting process of the sealing groove 1121 and the sealing protrusion 421, the relative movement direction is along the axial direction of the second plugging mechanism 1, which is consistent with the plugging direction of the second plugging mechanism 1 and the first plugging mechanism 2. During the plugging and mating process of the second plugging mechanism 1 and the first plugging mechanism 2, the snap-fitting of the sealing groove 1121 and the sealing protrusion 421 can be achieved. Specifically, the sealing groove 1121 can be set as a square opening with a certain depth, and the opening has a certain depth to facilitate the insertion and fixation of the sealing protrusion 421 in the splash-proof mechanism 4.

[0099] As Figure 3 shown, a guiding conical surface 1112 is provided at the connection between the first insertion portion 111 and the first operation portion 112. The guiding conical surface 1112 guides the splash-proof mechanism 4 so that the splash-proof mechanism 4 moves along the guiding conical surface 1112 to a position where the sealing groove 1121 and the sealing protrusion 421 are aligned.

[0100] Inside the first plug body 11 is a first liquid flow channel 114. The inner wall of the first liquid flow channel 114 is specially treated to have a smooth surface, so as to reduce the resistance when the coolant flows.

[0101] The first connection portion 113 is provided with a first external thread 1131. The first external thread 1131 is connected to the pipeline connected by the second plugging mechanism 1, or the first external thread 1131 is connected to the fixing mechanism 6 connected by the second plugging mechanism 1, which is specifically determined according to the actual situation.

[0102] The first plug body 11 in this specific embodiment can be made of a high-strength and corrosion-resistant metal material, such as stainless steel. Of course, it can also be set to other materials that meet the requirements, which is specifically determined according to the actual situation.

[0103] In this specific embodiment, through functional partitioning, double sealing, and human-machine interaction optimization, the plugging device achieves high reliability, ease of use, and safety, and is particularly suitable for industrial scenarios with strict requirements for sealing performance and operation efficiency. The radial dimension of the first operating part 112 is greater than that of the first plugging part 111, forming a physical limit to prevent over-insertion or deviation during plugging, ensuring accurate alignment during plugging; after the first plugging part 111 is engaged with the first plugging mechanism 2, the dimensional difference of the operating part can inhibit the axial movement of the plug under vibration or external force, improving the connection stability. After the dimension of the operating part is enlarged, a larger grasping area is provided, facilitating manual force application, especially suitable for narrow spaces or scenarios where gloves are worn for operation; the second sealing ring 32 is sleeved on the first connecting part 113 and is in close contact with the operating part, forming an axial compression seal to prevent the leakage of the medium along the thread gap. In addition, rapid connection with external devices is achieved through standardized threads, with strong adaptability.

[0104] In a specific embodiment, the first plugging mechanism 2 includes a second plug body 21, and the second plug body 21 includes a second plugging part 211, a pipeline connecting part 212, and a second connecting part 213 arranged in sequence; the second plugging part 211 is used for plugging and mating with the first plugging part 111, and an operation section 2111 with a hexagonal cross-section is arranged on the outer side wall of the second plugging part 211; the pipeline connecting part 212 is provided with a second external thread 2121 for connecting to an external device; the second connecting part 213 is provided with a tapered joint, and the cross-sectional dimension of the tapered joint gradually decreases from the end close to the pipeline connecting part 212 to the end far from the pipeline connecting part 212.

[0105] As Figure 7 shown, an operation section 2111 with a hexagonal cross-section is arranged on the outer side wall of the second plugging part 211 of the second plug body 21, and the operation section 2111 facilitates the operation of wrench tools; during the actual plugging and mating process, Figure 7 the second plugging part 211 of the second plug body 21 in Figure 3 is sleeved on the outer periphery of the first plugging part 111 of the first plug body 11 in

[0106] A second liquid flow channel 216 is formed inside the second plug body 21. The inner wall of the second liquid flow channel 216 is specially treated to have a smooth surface, so as to reduce the resistance during the flow of the coolant. When the first plug body 11 and the second plug body 21 are in a plugged and mated state, the first liquid flow channel 114 is communicated with the second liquid flow channel 216.

[0107] As Figure 7 shown, the second connecting part 213 is provided with a tapered joint, and the setting of the tapered joint facilitates the insertion of the second plugging part 211 into the interface of the liquid-cooled cabinet.

[0108] The radial dimension of the pipeline connection part 212 is larger than that of the second connection part 213. When the second connection part 213 is inserted into the interface of the liquid cooling cabinet, the step between the pipeline connection part 212 and the second connection part 213 can limit the position of the liquid cooling cabinet; in addition, as Figure 7 shown, the pipeline connection part 212 is provided with an external thread, and a pressure balance mechanism 5 can be connected to the external thread. Therefore, a second ventilation hole 215 is provided, and the second ventilation hole 215 communicates with the second liquid flow channel 216 in the second plug body 21 and the pressure balance cavity 5212 in the pressure balance mechanism 5; the pipeline connection part 212 is provided with a ring-shaped limiting protrusion with a relatively large radial dimension, and a gasket 214 is arranged on one side of the ring-shaped limiting protrusion facing the second connection part 213. One side of the gasket 214 in the circumferential direction is in contact with the ring-shaped limiting protrusion, and the other side is in contact with the pressure balance mechanism 5, so as to realize the tightening and positioning of the pressure balance mechanism 5.

[0109] In order to ensure that the second ventilation hole 215 and the pressure balance cavity 5212 can be just communicated after the pressure balance mechanism 5 is installed on the second plug body 21, the second external thread 2121 of the pipeline connection part 212 can be precisely designed, or positioning marks can be respectively set on the pressure balance mechanism 5 and the second plug body 21. When the two positioning marks coincide in the circumferential position, the communication between the second ventilation hole 215 and the pressure balance cavity 5212 can be realized.

[0110] In this specific embodiment, through the human-computer interaction optimization of the hexagonal operation section 2111, the adaptive sealing of the tapered joint and the flexible adaptation of the modular interface, high reliability, easy maintainability and wide scene applicability are achieved, especially suitable for industrial connection scenarios with strict requirements for sealing grade, operation efficiency and environmental adaptability. Among them, the angular structure of the hexagonal operation section 2111 can be adapted to standard wrench tools, providing uniform stress points to avoid slipping, especially suitable for high-torque operations in high-pressure scenarios; the hexagonal cross-section has direction recognition, and the angle can be quickly aligned during insertion to prevent misinsertion. The progressive contact surface of the tapered joint automatically corrects the coaxiality during tightening, forming uniform radial pressure and improving the sealing reliability; the tapered joint can be compatible with pipes of different materials and adapt to the pipe diameter tolerance by adjusting the taper.

[0111] The present application also provides a liquid cooling system, which includes a liquid cooling cabinet, a server chassis and the liquid cooling plug-in device according to any one of the above. The first plug-in mechanism 2 of the liquid cooling plug-in device is connected to the liquid cooling cabinet, and the second plug-in mechanism 1 of the liquid cooling plug-in device is connected to the server chassis.

[0112] During actual use, by inserting and mating the second plug-in mechanism 1 with the first plug-in mechanism 2, the liquid cooling pipelines of the liquid cooling cabinet and the server chassis can be connected to dissipate heat from the server chassis.

[0113] As the "heart" of the coolant circulation, the liquid-cooled cabinet is responsible for the pressurization, temperature regulation, filtration, and flow distribution of the coolant, including a pump unit, a heat exchanger, a liquid storage tank, and a control module. The pump unit provides the circulating power; the heat exchanger cools the returned warm coolant through external cold water or cold air; the liquid storage tank balances the system pressure fluctuations and stores standby coolant; the control module integrates temperature, pressure, and flow sensors to monitor and adjust the operating parameters in real time.

[0114] The server chassis includes cold plate type and immersion type. During the actual assembly process, the first plugging mechanism 2 can be first connected to the liquid-cooled pipeline in the liquid-cooled cabinet, and the anti-splash mechanism 4 can be installed on the first plugging mechanism 2. The second plugging mechanism 1 is connected to the cooling structure in the server chassis, and then the second plugging mechanism 1 is plugged and matched with the first plugging mechanism 2 to realize the connection between the cooling structure in the server chassis and the liquid-cooled pipeline in the liquid-cooled cabinet; during the plugging and matching process of the second plugging mechanism 1 and the first plugging mechanism 2, the anti-splash mechanism 4 is hermetically connected to the outer side wall of the second plugging mechanism 1.

[0115] When the liquid-cooled system in this specific embodiment connects the liquid-cooled pipeline in the liquid-cooled cabinet and the cooling structure in the server chassis, it is connected through the above-mentioned liquid-cooled plugging device. Since the liquid-cooled plugging device is provided with an anti-splash mechanism 4, and the anti-splash mechanism 4 is provided with a receiving cavity 411 that can accommodate the splashing liquid. The receiving cavity 411 is sleeved on the plugging connection between the second plugging mechanism 1 and the first plugging mechanism 2, and one end of the axial direction of the receiving cavity 411 is hermetically connected to the outer side wall of the second plugging mechanism 1, and the other end is hermetically connected to the outer side wall of the first plugging mechanism 2; the receiving cavity 411 of the anti-splash mechanism 4 completely covers the plugging connection between the second plugging mechanism 1 and the first plugging mechanism 2, and the receiving cavity 411 is hermetically connected to the plugging connection between the second plugging mechanism 1 and the first plugging mechanism 2, which can effectively collect the splashing liquid and prevent the splashing liquid from leaking. Therefore, the technical problem of the coolant directly splashing into the external environment can be solved, and the technical effect of improving the safety of the liquid-cooled system can be achieved. It can effectively prevent the coolant in the connection pipeline between the liquid-cooled pipeline in the liquid-cooled cabinet and the cooling structure in the server chassis from leaking to the external environment.

[0116] On the basis of the above embodiment, the liquid-cooled plugging device further includes a fixing mechanism 6. The fixing mechanism 6 is fixed on the server chassis. The fixing mechanism 6 is provided with a pipeline connection structure 62. One end of the pipeline connection structure 62 is connected to the liquid-cooled pipeline of the server chassis, and the other end of the pipeline connection structure 62 is threadedly connected to the second plugging mechanism 1.

[0117] Such as Figure 15As shown in the figure, the fixing mechanism 6 includes an installation main body 61 and a pipeline connection structure 62. Among them, the installation main body 61 is die-cast, ensuring its own strength and the fixing strength of the liquid cooling plug on it; the pipeline connection structure 62 can adopt a threaded connection method and is equipped with a locking nut. By tightening the locking nut, the second plugging mechanism 1 is firmly connected to the coolant pipeline; the installation main body 61 is provided with screw through holes 64, and the screw through holes 64 serve as bottom holes for locking the floating mechanism 7 and the fixing mechanism 6 together. Of course, in the case of no floating mechanism 7, the fixing mechanism 6 can also be fixedly connected to the server chassis through the screw through holes 64.

[0118] During the actual assembly process, in order to enable the server chassis to achieve positioning installation when connected to the liquid cooling cabinet, a guiding pin can be set on one of the liquid cooling cabinet and the fixing mechanism 6, and a guiding pin hole 63 for cooperating with the guiding pin can be set on the other of the liquid cooling cabinet and the fixing mechanism 6. Both the guiding pin and the guiding pin hole 63 are arranged along the axial direction of the second plugging mechanism 1.

[0119] In this specific embodiment, by setting the guiding pin and the guiding pin hole 63, it can guide during the installation process of the server chassis. At the same time, the cooperation between the guiding pin hole 63 and the guiding pin can limit the installation of the fixing mechanism 6 to improve the installation accuracy of the fixing mechanism 6.

[0120] The fixing mechanism 6 in this specific embodiment plays a role in connecting the cooling pipeline in the server chassis and the second plugging mechanism 1. During the assembly process, the fixing mechanism 6 can be installed on the server chassis in advance, and then the second plugging mechanism 1 can be installed on the fixing mechanism 6, which is convenient for installing the second plugging mechanism 1 and simplifies the installation process. In addition, the setting of the fixing mechanism 6 can effectively ensure that the liquid cooling plug-in device always maintains a firm connection during the operation of the server. The guiding pin hole 63 of the fixing mechanism 6 and the floating mechanism 7 solve the problems of structural damage and channel leakage caused by inaccurate blind plugging of the liquid cooling head, ensuring the normal circulation of the coolant and improving the stability of the liquid cooling system.

[0121] In a specific embodiment, the liquid cooling system further includes a floating mechanism 7. The floating mechanism 7 includes a mounting seat 71 fixedly arranged on the liquid cooling cabinet and a floating connecting piece 72 connected to the fixing mechanism 6. The mounting seat 71 is provided with a floating hole, and the floating connecting piece 72 passes through the floating hole and is connected to the fixing mechanism 6. The radial dimension of the floating hole is larger than the radial dimension of the floating connecting piece 72, so that the fixing mechanism 6 can move radially relative to the floating mechanism 7; a floating spring 73 is sleeved on the outer periphery of the floating connecting piece 72. One end of the floating spring 73 abuts against the mounting seat 71, and the other end abuts against the fixing mechanism 6, so that the fixing mechanism 6 can move axially relative to the floating mechanism 7.

[0122] As Figure 16As shown in the figure, the mounting base 71 of the floating mechanism 7 can be fixedly arranged on the server chassis. The mounting base 71 is provided with a floating hole, and the aperture of the floating hole is larger than the radial dimension of the floating connecting piece 72. The floating connecting piece 72 can move along any radial direction in the floating hole, and the other end of the floating connecting piece 72 is fixedly arranged on the fixing mechanism 6, and the fixing mechanism 6 is connected to the second plugging mechanism 1. In addition, the outer periphery of the floating connecting piece 72 is sleeved with a floating spring 73. One end of the floating spring 73 abuts against the mounting base 71, and the other end abuts against the fixing mechanism 6, so that the fixing mechanism 6 can move axially relative to the floating mechanism 7.

[0123] During the process of the second plugging mechanism 1 being plugged into the first plugging mechanism 2, since the second plugging mechanism 1 is connected to the fixing mechanism 6 and the fixing mechanism 6 can move both radially and axially relative to the mounting base 71, the second plugging mechanism 1 can move both radially and axially relative to the mounting base 71. When there is a positional deviation between the second plugging mechanism 1 and the first plugging mechanism 2, the alignment between the second plugging mechanism 1 and the first plugging mechanism 2 can be achieved by adjusting the radial position of the second plugging mechanism 1 relative to the mounting base 71, which is beneficial to improving the success rate of the plugging cooperation during the blind plugging process. In addition, since the second plugging mechanism 1 can move axially relative to the mounting base 71, during the plugging cooperation between the second plugging mechanism 1 and the first plugging mechanism 2, the collision between the second plugging mechanism 1 and the first plugging mechanism 2 can be avoided, and the plugging force can be effectively buffered, improving the plugging effect.
