Description

Technical Field

[0001] This invention belongs to the field of conductive connection technology, specifically a liquid-electric integrated conductive connection device. Background Technology

[0002] With the rapid development of cloud computing, artificial intelligence, and 5G technologies, data centers are facing increasingly higher demands for computing power density and energy efficiency. Modern data centers generally adopt high-density rack deployments (with single rack power densities reaching 20kW-50kW), achieving efficient use of space and energy through centralized and modular design. However, high-density racks currently deployed for industrial gateways and peripheral computing nodes (such as server chassis) face the following core challenges.

[0003] Power transmission is one of the core functions of a server, and its efficiency and stability directly affect the overall performance of a data center. Currently, the power transmission process faces the following prominent problems:

[0004] Current industrial gateway cabinets primarily use traditional spring-pin or sheet-terminal contact connectors for power transmission. These connectors have limited contact area, resulting in high contact resistance, making them prone to overheating under high current loads and exhibiting poor conductivity. More importantly, industrial environments often experience continuous vibration, and traditional snap-fit ​​or threaded fasteners are prone to loosening under prolonged vibration, leading to connection interruptions or a sudden increase in contact resistance. This can not only cause restarts and data packet loss in industrial gateways and their subordinate nodes within the data center, but also easily trigger electric arcs or fires, posing a serious threat to production safety. As the central nervous system, a momentary interruption of power to the industrial gateway can cause the data link of the entire local production network to collapse, resulting in significant losses.

[0005] Data center servers may be deployed in vibrating environments. Traditional clip or threaded fastening methods are prone to loosening under long-term vibration, leading to connection interruption or instantaneous increase in contact resistance, which can easily cause electric arcs or fires.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. This invention significantly increases the contact area between the plug and the conductive socket by uniformly distributing conductive protrusions on the inner wall of the conductive socket, effectively reducing contact resistance and improving conductivity. Simultaneously, the insulating layer inside the cable connector uses a highly insulating material to completely encapsulate the battery cell, eliminating the risk of short circuits caused by contact between the battery cell and the external environment, thus ensuring the stability and safety of power transmission.

[0026] 2. This invention achieves rapid and precise connection and mechanical fixation of male and female cable connectors through a beveled snap-fit ​​design of the snap-fit ​​block and guide groove, combined with an axial positioning structure of the guide rod and guide hole. The triangular bevel at the front end of the snap-fit ​​block automatically corrects the angle and generates pre-tightening force during insertion, while the narrow end of the guide rod automatically guides the connection, ensuring stability even under long-term vibration. This completely solves the problems of easy loosening and instantaneous increase in contact resistance leading to arcing or fire associated with traditional snap-fit ​​or threaded fixing methods, significantly improving the reliability and safety of data center cabinets.

[0027] 3. By placing the cable inside the liquid cooling pipe, the present invention can, on the one hand, dissipate heat from the cable itself with the help of the liquid cooling pipe, thereby improving the heat dissipation efficiency of the cable and ensuring its stable performance; on the other hand, the integrated design of the cable and the liquid cooling pipe reduces the phenomenon of cable messiness, making the cables in the cabinet easier to organize and manage, which is conducive to the heat dissipation of the entire cabinet and solves the problems of poor heat dissipation of cables and messiness affecting the overall heat dissipation in the cabinet.

[0028] 4. By setting up a sealing component, when the second connector and the first connector are connected, the first sealing component and the second sealing component open to allow liquid flow; when the connector is separated, the sealing component automatically closes, effectively preventing the coolant in the liquid cooling pipe and liquid cooling device from flowing out, thus avoiding resource waste and safety hazards.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] like Figures 1 to 4 As shown, the present invention provides a liquid-electric integrated conductive connection device, including a host cabinet 1 and multiple server chassis disposed in the host cabinet 1, wherein the host cabinet 1 is provided with a plurality of connecting main cables 2;

[0049] The main connecting cable 2 is provided with cables 7 for power transmission to each server chassis, and both ends of the cables 7 extend outside the main connecting cable 2; the cables 7 and the server chassis are respectively connected to the male cable connector 701 and the female cable connector 702;

[0050] The outer end of the male cable connector 701 forms a plug 703 that is electrically connected to the cable 7; the outer end of the female cable connector 702 has a mating cavity 704, and the mating cavity 704 has a conductive plug 705 that is adapted to the plug 703. The female cable connector 702 has a battery cell 706 for conducting the conductive plug 705 and the power supply terminal of the server chassis; the inner wall of the conductive plug 705 has uniformly distributed conductive protrusions 707.

[0051] The main unit cabinet 1 contains several main cables 2. The cables 7 in the main cables 2 are used to connect various server chassis to achieve power transmission. The two ends of the cable 7 are connected to a male cable connector 701 and a female cable connector 702, respectively. The male cable connector 701 has a plug 703 at its outer end that is electrically connected to the cable 7. The female cable connector 702 has a mating cavity 704 at its outer end. The mating cavity 704 contains a conductive plug 705 that is compatible with the plug 703. The female cable connector 702 contains a battery 706 for conducting electricity between the conductive plug 705 and the power supply terminal of the server chassis. The conductive protrusions 707 are evenly distributed on the inner wall of the conductive plug 705. Power transmission is achieved by inserting the plug 703 into the conductive plug 705. The conductive protrusions 707 increase the contact area and ensure conductivity.

[0052] It should be added that the conductive protrusion is made of silver-based rare earth composite material (such as Ag-CeO2) through powder metallurgy process, which has low contact resistance, high oxidation resistance and long life, and meets the application requirements of new electrical contact precious metal materials.

[0053] In one embodiment, the female cable connector 702 has an insulating layer 708 that covers the battery core 706; the outer end of the male cable connector 701 is also provided with a locking block 709 located adjacent to the plug 703 on one side; the outer end of the female cable connector 702 has a fixing part 7010 facing the locking block 709; the fixing part 7010 is provided with a guide groove 7011 that matches the locking block 709;

[0054] When the locking block 709 completely penetrates the guide groove 7011, it engages with the inner edge of the guide groove 7011.

[0055] The female cable connector 702 is provided with an insulating layer 708 covering the battery cell 706 to protect the battery cell 706; the male cable connector 701 has a locking block 709 on the outer end adjacent to the plug 703, and the female cable connector 702 has a corresponding fixing part 7010 on the outer end. The fixing part 7010 has a guide groove 7011 that matches the locking block 709. When the male cable connector 701 and the female cable connector 702 are connected, the locking block 709 is inserted along the guide groove 7011, and after being fully inserted, it is engaged with the inner edge of the guide groove 7011, thereby fixing the connection between the male cable connector 701 and the female cable connector 702.

[0056] The core function of the insulating layer 708 encasing the battery cell 706 is to prevent short circuits caused by direct contact between the battery cell and the external environment, while ensuring the stability and safety of power transmission. The insulating layer 708 can be made of materials such as polyimide (PI), polyethylene terephthalate (PET), or polytetrafluoroethylene (PTFE). Completely encasing the battery cell 706 eliminates the risk of short circuits caused by contact between the battery cell and the external environment, ensuring the stability and safety of power transmission, making it particularly suitable for high-power power transmission scenarios in high-density cabinets.

[0057] In one embodiment, the front end of the card block 709 forms a triangular fixing part with an inclined surface close to the guide groove 7011; the inner surface of the docking cavity 704 and the outer surface of the plug 703 are both formed with matching guide planes 9;

[0058] The docking cavity 704 is also provided with a guide rod 7012 along the axial direction, and the plug 703 is provided with a guide hole 7013 adapted to the guide rod 7012 along the axial direction; the outer end of the guide rod 7012 narrows inward.

[0059] Through the inclined engagement of the locking block 709 and the guide groove 7011, the anti-deflection design of the guide plane 9, and the axial positioning of the guide rod 7012 and the guide hole 7013, this structure achieves rapid and accurate docking, mechanical fixing, and vibration resistance of the male cable head 701 and the female cable head 702, ensuring the stability and reliability of power transmission.

[0060] In addition, server racks in data centers generate a large amount of heat during operation, and heat dissipation efficiency directly affects equipment performance and lifespan. Traditional heat dissipation methods often use air cooling, but its heat dissipation capacity is limited and its energy consumption is high. Currently, some sites use more efficient liquid cooling, which achieves efficient heat dissipation by circulating liquid cooling between the server and the liquid cooling device. However, during maintenance and disassembly of the liquid cooling pipes, coolant can easily leak out from the liquid cooling pipes and the liquid outlets on the server, which not only wastes coolant but may also cause safety hazards such as short circuits. To address this, the present invention has made the following improvements:

[0061] As one implementation method, such as Figures 5-17 As shown, the main connecting cable 2 is also equipped with a liquid-cooled inner tube 3 arranged adjacent to the cable 7; both ends of the liquid-cooled inner tube 3 are provided with connecting mechanisms. The liquid-cooled inner tube 3 is used to connect the liquid cooling device and the server chassis so that the server chassis and the liquid cooling device can cooperate to dissipate heat; the liquid-cooled inner tube 3 is connected to the liquid cooling system pipeline of the server chassis and the external liquid cooling device (such as a water chiller). After absorbing heat, it flows through the external cold source to cool down, forming an efficient heat dissipation cycle, which will not be described in detail here.

[0062] Cable 7 is located inside the main cable 2. The liquid-cooled inner tube 3 can also be used to dissipate heat from cable 7. It is known that the main cabinet for data centers is existing technology. Therefore, the connection method of the liquid-cooled inner tube 3 and the arrangement of each structure will not be described in detail later.

[0063] The connecting mechanism includes a second connector 11 and a first connector 30. A first sealing component and a second sealing component are respectively provided in the second connector 11 and the first connector 30. When the second connector 11 and the first connector 30 are connected, the first sealing component and the second sealing component are opened; when the second connector 11 and the first connector 30 are separated, the first sealing component and the second sealing component are closed to prevent the coolant in the liquid cooling inner tube 3 and the liquid cooling device from flowing out.

[0064] The first connector 30 includes a first tube 31, on which a conical ring 33 and a limiting ring 32 are fixedly connected. A hollow frame 34 is fixedly connected inside the first tube 31, and the outer wall of the conical ring 33 has multiple insertion holes 38. The shape of the conical ring 33 facilitates the smooth insertion of the first tube 31 into the second connector 11, and the multiple insertion holes 38 on its outer wall provide insertion positions for the locking post 28.

[0065] The second connector 11 includes a second tube body 20. An annular groove 22 is formed on the outer peripheral side wall of the second tube body 20. A sliding ring 24 is slidably connected in the annular groove 22. A sliding sleeve 12 is fixedly connected to the outer end of the sliding ring 24. The sliding sleeve 12 is located on the outer periphery of the second tube body 20, and a second spring 23 is installed in the annular groove 22. A plurality of through holes 27 are formed on the second tube body 20. A locking post 28 is elastically installed in the plurality of through holes 27. The inner end of the locking post 28 is inserted into the insertion hole 38. When the first tube body 31 is inserted into the second tube body 20 and fixed, the outer end of the locking post 28 abuts against the sliding ring 24. When the sliding sleeve 12 slides to one end, the locking post 28 gradually gets out of the constraint, so that the locking post 28 gets out of the insertion hole 38.

[0066] By setting the sliding sleeve 12, the constraint state of the locking post 28 can be controlled, realizing the quick connection and separation of the connector. When the sliding sleeve 12 slides to one end, the constraint of the sliding ring 24 on the outer end of the locking post 28 gradually decreases until it no longer constrains the outer end of the locking post 28. Under the reset action of the third spring 29, the locking post 28 moves outward, thereby disengaging from the insertion hole 38, and thus the two connectors can be separated.

[0067] During installation, the first tube 31 is inserted into the second tube 20, and the conical ring 33 on the first tube 31 is inserted into the conical groove 18. During this process, the locking post 28 is squeezed by the first tube 31, which compresses the third spring 29. Then, the insertion continues, and the locking post 28 slides on the first tube 31 and the conical ring 33, and finally enters the insertion hole 38 on the conical ring 33. At this time, under the elastic reset action of the third spring 29, the locking post 28 is inserted into the insertion hole 38 and fixed, thereby fixing the two connectors.

[0068] The inner wall of the sliding ring 24 is a slope structure 26, and a retaining ring 25 is fixedly connected at the lowest point of the slope structure 26. The retaining ring 25 and the second spring 23 are in contact.

[0069] The locking post 28 is limited to slide within the through hole 27, and a third spring 29 is sleeved on the through hole 27. The third spring 29 keeps the locking post 28 in an inwardly pressed state.

[0070] Hollow frame 34 and fixed ring 13 are fixedly connected in both the first and second sealing components. A movable cavity 42 is formed between the hollow frame 34 and the fixed ring 13. A tapered groove 18 is provided at the outer end of the fixed ring 13, and a through hole is provided between the inner end of the tapered groove 18 and the movable cavity 42.

[0071] A first T-shaped block 14 is slidably connected in the through hole of the second tube 20. A first push rod 15 is fixedly connected to one end of the first T-shaped block 14. A first T-shaped groove 17 is opened in the first push rod 15. A top tube 16 is fixedly connected to the other end of the first T-shaped block 14. A first spring 19 is sleeved on the top tube 16 and abuts against the hollow frame 34. When the fixing ring 13 abuts against the protrusion 39 on the first T-shaped block 14, the channel in the second tube 20 is closed. A second T-shaped block 35 is slidably connected in the through hole of the first tube 31. A fourth spring 36 is installed at one end of the second T-shaped block 35 and abuts against the hollow frame 34. A second T-shaped groove 37 is opened at the other end of the second T-shaped block 35. When the fixing ring 13 abuts against the protrusion 39 on the second T-shaped block 35, the channel in the first tube 31 is closed.

[0072] By setting the first sealing component and the second sealing component, in the uninserted state, the second T-shaped block 35 in the first sealing component is pressed by the fourth spring 36, so that the protrusion 39 on it is pressed against the side wall of the fixing ring 13; the first T-shaped block 14 in the second sealing component is pressed by the first spring 19, so that the protrusion 39 on it is pressed against the side wall of the fixing ring 13. Therefore, in the uninserted state, the first sealing component and the second sealing component are in a closed state.

[0073] During insertion, the first tube 31 is inserted into the second tube 20, and the two tubes are fixed by the cooperation of the locking post 28 and the insertion hole 38. During the process of the first tube 31 in the first sealing assembly, the second T-shaped block 35 in the first tube 31 presses the first push rod 15 on the first T-shaped block 14. First, the second T-shaped block 35 moves inward, and the protrusion 39 on the second T-shaped block 35 disengages from and contacts the fixing ring 13 in the first tube 31, and the fourth spring 36 is in a compressed state. Immediately afterwards, the first T-shaped block 14 moves inward, and the protrusion 39 on it disengages from and contacts the fixing ring 13 in the second tube 20, and the first spring 19 is in a compressed state. Since the two T-shaped blocks disengage from the two fixing rings 13 respectively, the two T-shaped blocks are connected through the first T-shaped groove 17 and the second T-shaped groove 37, so that the first assembly and the second assembly are in an open state, and the coolant can flow and circulate smoothly.

[0074] When pulled out, the fourth spring 36 in the first sealing assembly resets, causing the second T-block 35 to reset, and the first spring 19 in the second sealing assembly resets the first T-block 14, thereby completing the sealing.

[0075] One end of the fixing ring 13 has an annular groove, and a washer 40 is fixedly connected to the end of the protrusion 39 near the fixing ring 13. The size of the washer 40 matches that of the annular groove.

[0076] The inner wall of the fixing ring 13 inside the second tube 20 is provided with an installation groove, and a sealing ring 21 is fixedly connected in the installation groove. When the first tube 31 is inserted into the second tube 20, the sealing ring 21 and the first tube 31 come into contact. A detachable connecting head 10 is installed on both the first connector 30 and the second connector 11. The connecting head 10 is prior art. One end is connected to the connector, and the other end is connected to the liquid cooling inner tube 3. The structure of this connecting head 10 is prior art and will not be described in detail later.

[0077] The sealing ring 21 is made of tin-based electronic packaging material, which has excellent sealing performance and corrosion resistance. It is suitable for high-frequency insertion and removal scenarios and ensures long-term sealing reliability of the liquid cooling circuit.

[0078] An outer tube 4 surrounds the liquid-cooled inner tube 3. The liquid-cooled inner tube 3 includes an embedding groove 6, and the middle part of the cable 7 is installed in the embedding groove 6. A hollow cavity 5 is formed between the liquid-cooled inner tube 3 and the outer tube 4. Multiple heat sinks 8 are fixedly connected to the outer wall of the liquid-cooled inner tube 3. The multiple heat sinks 8 pass through the outer tube 4 and extend outward. An overflow pipe 41 connected to the hollow cavity 5 is fixedly connected to the outer tube 4. During long-term operation, if there is a large temperature difference between the liquid-cooled inner tube 3 and the outside environment, water vapor in the air may condense on the outer wall of the cable. By setting up the hollow cavity 5 formed by the liquid-cooled inner tube 3 and the outer tube 4, the condensate can gradually flow into the hollow cavity 5. On the one hand, the condensate can be collected to prevent the condensate from flowing into the server rack and causing short circuits or other safety hazards. On the other hand, the condensate is wrapped around the liquid-cooled inner tube by the outer tube 4. The surface of the inner liquid-cooled tube 3 increases the equivalent heat dissipation area, which can assist the coolant in the inner liquid-cooled tube 3 in heat dissipation and further improve the heat dissipation effect. The multiple heat sinks 8 fixedly connected to the outer wall of the inner liquid-cooled tube 3 are made of aluminum alloy or pure copper. The heat sinks 8 penetrate the outer tube 4 and extend outward to increase the heat dissipation area. When the coolant circulates in the inner liquid-cooled tube 3, it absorbs the heat generated by the cable 7 and transfers it to the outer wall of the inner liquid-cooled tube 3. Then, the heat is dissipated to the surrounding environment through the heat sinks 8. The design of the heat sinks 8 increases the heat dissipation area and improves the heat dissipation efficiency. The overflow pipe 41 on the outer tube 4 is connected to the hollow cavity 5 and can be connected to the external collection box. When the condensate in the hollow cavity 5 accumulates to a certain amount, the excess coolant or condensate will flow into the external collection box through the overflow pipe 41, which is conducive to subsequent drainage and maintenance.

[0079] The working principle of this invention is as follows: In use, the first tube 31 of the first connector 30 is inserted into the second tube 20 of the second connector 11. During the insertion process, the conical ring 33 on the first tube 31 guides it to be inserted smoothly. At the same time, the locking post 28 is squeezed and moves outward under the action of the third spring 29. When the insertion hole 38 on the conical ring 33 is aligned with the locking post 28, the locking post 28 is inserted into the insertion hole 38 under the reset action of the third spring 29, thus fixing the two connectors. At this time, the first sealing component and the second sealing component are opened, and the coolant in the liquid cooling inner tube 3 and the liquid cooling device begins to circulate. When the first tube 31 is inserted to the bottom, if the locking post 28 is not inserted into the insertion hole 38 smoothly, the first tube 31 can be rotated to insert the locking post 28 into the insertion hole 38.

[0080] The coolant in the liquid cooling device circulates between the server chassis and the main unit cabinet 1 through the liquid cooling inner pipe 3 to dissipate heat from the server chassis. At the same time, the cable 7 is located inside the connecting main cable 2. While the connecting main cable 2 is dissipating heat from the server, it also dissipates heat from the cable 7, thus improving the performance stability of the cable 7.

[0081] If condensation occurs on the outer wall of cable 7 due to water vapor in the air upon cooling during prolonged operation, the condensate can gradually flow into the hollow cavity 5 formed between the inner liquid cooling tube 3 and the outer tube 4. This prevents condensate from flowing into the server rack 1 and causing safety hazards such as short circuits. On the other hand, the condensate wraps around the surface of the inner liquid cooling tube 3 through the outer tube 4, increasing the effective heat dissipation area of ​​the inner liquid cooling tube 3 and assisting the coolant in the inner liquid cooling tube 3 in heat dissipation, further improving the heat dissipation effect. At the same time, the multiple heat sinks 8 fixedly connected to the outer wall of the inner liquid cooling tube 3 can increase the heat dissipation area. When the coolant circulates in the inner liquid cooling tube 3, it absorbs the heat generated by cable 7 and transfers it to the outer wall of the inner liquid cooling tube 3, and then dissipates the heat to the surrounding environment through the heat sinks 8.

[0082] It should be noted that the heat sink 8 is made of porous copper-zinc composite material, and an open pore structure is formed by powder metallurgy, which significantly increases the heat dissipation area and improves the heat dissipation efficiency of the liquid cooling system.

[0083] When maintenance or repair of the main cable 2 or server chassis is required, the sliding sleeve 12 is slid to one end, and the constraint of the sliding ring 24 on the outer end of the locking post 28 is gradually reduced. The locking post 28 moves outward under the reset action of the third spring 29 and disengages from the socket 38. At this time, the first connector 30 and the second connector 11 can be separated. During the separation process, the first sealing component and the second sealing component are closed to prevent the coolant in the liquid cooling inner tube 3 and the liquid cooling device from flowing out.
