[0031] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them.

[0033] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] The embodiments of the present application provide an intelligent bridging device and an intelligent bridging method. The device is described in detail in combination with the structure and working principle of the intelligent bridging device (the technical terms involved must be explained).

[0035] like Figures 1 to 6As shown, the intelligent bridging device includes a box 10, a confluence component 20 and a plurality of liquid cooling units, wherein the box 10 has a receiving cavity; the confluence component 20 is arranged in the receiving cavity, and the confluence component 20 has a first confluence port 21, a second confluence port 22, a third confluence port 23, and a cabinet interface 24. The first confluence port 21, the second confluence port 22, and the third confluence port 23 are selectively connected to the cabinet interface 24 through an electric ball valve 25. The cabinet interface 24 is used to connect with the inlet of the liquid cooling cabinet; the plurality of liquid cooling units are all arranged in the receiving cavity, and the plurality of liquid cooling units include at least a gas path analysis Pressure maintaining module 30, flow pressure monitoring module 40, secondary evaporation filtration module 50; wherein, the inlet of the gas path analysis and pressure maintaining module 30 is used to connect with the outlet of the cold plate inflation and leak detection system, and the outlet of the gas path analysis and pressure maintaining module 30 is connected with the first confluence 21; the inlet of the flow pressure monitoring module 40 is used to connect with the outlet of the constant pressure liquid injection system, and the outlet of the flow pressure monitoring module 40 is connected with the second confluence 22; the inlet of the secondary evaporation filtration module 50 is used to connect with the outlet of the drying and nitrogen injection system, and the outlet of the secondary evaporation filtration module 50 is connected with the third confluence 23.

[0036] The intelligent bridging device provided in the present application can realize intelligent bridging and dynamic maintenance between multiple liquid cooling units and liquid cooling cabinets. By setting multiple liquid cooling units into a structural form including a gas path analysis and pressure maintenance module 30, a flow pressure monitoring module 40, and a secondary evaporation and filtration module 50, matching tests of helium detection and pressure maintenance, constant pressure liquid injection, and drying and nitrogen injection of the liquid cooling cabinet are realized, ensuring the diversity and accuracy of the test, and solving the problem that the existing technology cannot provide an effective solution for intelligent bridging and dynamic maintenance between multiple liquid cooling units and liquid cooling cabinets.

[0037] like Figure 1 and Figure 2As shown, the box body 10 is composed of a profile frame 11, side sealing panels 12, a main power switch 13, a front door panel 14, and a rear door panel 15. One side of the front door panel is the docking side for multiple liquid cooling units, and the liquid cooling unit docking connectors are arranged separately. A touch screen 16 is designed in the middle position of one side of the front door panel. After scanning the code of the liquid cooling cabinet, the configuration to be tested can be directly imported into the algorithm software for decomposition and reconstruction, and the test program is generated in sequence. The intermediate PLC component controls the whole machine test. At the same time, the touch screen 16 provides a convenient human-computer interaction interface, which is convenient for manual intervention, debugging and troubleshooting in emergency situations. A system status indicator light 17 is set on the upper part of one side of the front door panel to monitor the status of the equipment control system, gas path analysis and pressure maintenance module 30, flow pressure monitoring module 40 and secondary evaporation and filtration module 50, respectively, so that personnel can control the test information in real time. A three-color light 18 is equipped on the top to display the normal / abnormal working status of the whole machine. One side of the rear door panel 15 is the docking side of the liquid cooling cabinet, where the docking joint of the liquid cooling cabinet, namely the cabinet interface 24, is arranged. The rear door on one side of the rear door panel 15 is a semi-enclosed structure. After half of the door is opened, internal abnormalities can be viewed and detected. The built-in water collection tray can avoid the impact of abnormal situations such as pipe leakage on the on-site environment. A manually opened and closed observation window 110 is provided on the side half-enclosed door for viewing the working status of the temperature and humidity transmitter. A system status indicator light group 111 is also provided on the upper part of one side of the rear door panel 15, which respectively monitors the status of the equipment control system, the gas path analysis and pressure maintaining module 30, the flow pressure monitoring module 40 and the secondary evaporation and filtration module 50 system, making it convenient for personnel to control the test information in real time from the other side.

[0038] like Figure 3 As shown, the air path analysis pressure maintaining module 30 includes a first ventilation pipe 31, and the two ends of the first ventilation pipe 31 respectively form the inlet and outlet of the air path analysis pressure maintaining module 30. In the direction from the inlet to the outlet of the air path analysis pressure maintaining module 30, the first ventilation pipe 31 is sequentially provided with a first manual ball valve 32, a first electric ball valve 33, a first filter 34, a circulation pump 35, a concentration component analyzer 36, a pressure gauge 37, a second electric ball valve 38, and a second manual ball valve 39.

[0039] Specifically, the gas path analysis and pressure maintaining module 30 is connected to the cold plate inflation leak detection system. Before the cabinet is supplied with water, the liquid cooling channel in the node / cabinet needs to be tested for air tightness. The conventional inflation leak detection system is a helium detection system, which uses a helium mass spectrometry leak detection method to detect leaks in the pipeline. This method is sensitive to detecting small leaks, but has high requirements on the environment and generally adds a nitrogen circuit to detect large leaks. In this way, there is a mixed detection of nitrogen and helium, which may affect the overall result abnormally. The gas path analysis and pressure maintaining module 30 can effectively solve such problems. Gas enters the gas circuit from the inlet through the first manual ball valve 32, passes through the first electric ball valve 33, and reaches the first filter 34. Here, the first filter 34 uses a three-element separation and collection module to separate and process the gas. The treated gas flow has a reduced pressure due to component separation, which may be insufficient. After being pressurized and circulated by the circulation pump 35, it is input into the concentration component analyzer 36 to analyze whether the required gas concentration value meets the requirements. If it is abnormal, an alarm is issued. If it is normal, the pressure is stored and maintained in the analyzer. When the pressure gauge 37 indicates that the pressure reaches the required pressure, the second electric ball valve 38 will open, and the gas will flow out through the second manual ball valve 39 to the confluence component 20 and then into the liquid cooling cabinet through the docking interface (i.e., cabinet interface 24) of the liquid cooling cabinet. At the same time, supercritical CO2 and ultrasonically vibrated nitrogen are alternately introduced, combined with ultrapure water. This alternating gas-liquid two-phase impact can effectively remove impurities in the pipeline and the inner wall of the cabinet, achieving a cleanliness level of up to NAS 1638 Class 4.

[0040] like Figure 4 As shown, the flow and pressure monitoring module 40 includes a liquid pipeline 41, and the two ends of the liquid pipeline 41 respectively form the inlet and outlet of the flow and pressure monitoring module 40. In the direction from the inlet to the outlet of the flow and pressure monitoring module 40, the liquid pipeline 41 is sequentially provided with a third manual ball valve 42, a third electric ball valve 43, a second filter 44, a booster pump 45, a flow pressure gauge 46, a relief valve 47, a temperature transmitter 48, a fourth electric ball valve 49, and a fourth manual ball valve 410.

[0041] Furthermore, in an embodiment not shown in the figures of the present application, the intelligent bridging device also includes a control module, which is connected to the temperature transmitter 48 by signal, so that the control module automatically adjusts the flow rate and pressure of the coolant according to the temperature information of the coolant monitored in real time by the temperature transmitter 48.

[0042] Specifically, the flow pressure monitoring module 40 is connected to the constant pressure liquid injection system. Before the water supply management and whole machine testing of the liquid cooling cabinet are carried out, the liquid cooling channel in the liquid cooling cabinet needs to be injected and the internal liquid cooling circuit needs to be flushed. The purified cleaning liquid flows out from the constant pressure liquid injection equipment, passes through the third manual ball valve 42 and the third electric ball valve 43, and flows into the second filter 44. The filter element of the second filter 44 is replaced with a multi-mesh mesh structure of ultra-fiber composite material, which can finely filter the purified cleaning liquid and isolate and filter the bacterial flora to ensure that the cleaning liquid flowing through will not cause pollution to the interior of the cabinet. The booster pump 45 then pressurizes the pipeline fluid and flows into the temperature transmitter 48. The flow pressure is set in the middle pipeline. The force gauge 46 is used to monitor the pressure and flow of the pipeline fluid in real time. A spring-energy storage quick-break relief valve 47 is set to avoid irreversible effects on the pipeline due to excessive internal pressure. The temperature transmitter 48 can measure the temperature of the fluid in the pipeline in real time and feed the data back to the control module to achieve temperature closed-loop regulation. At the same time, the integrated pressure mutation recognition algorithm can intelligently identify the internal pressure mutation amount and achieve double emergency safety interlock with the relief valve 47, thereby realizing the overall flow control of the liquid cooling system. After passing through the temperature transmitter 48, the fluid flows out to the confluence component 20 through the fourth electric ball valve 49 and the fourth manual ball valve 410 and flows into the liquid cooling cabinet through the docking interface of the liquid cooling cabinet (i.e., the cabinet interface 24).

[0043] like Figure 5 As shown, the secondary evaporation and filtration module 50 includes a second ventilation pipe 51, and the two ends of the second ventilation pipe 51 respectively form the inlet and outlet of the secondary evaporation and filtration module 50. In the direction from the inlet to the outlet of the secondary evaporation and filtration module 50, the second ventilation pipe 51 is sequentially provided with a fifth manual ball valve 52, a fifth electric ball valve 53, a third filter 54, a filter evaporator 55, a humidity transmitter 56, a sixth electric ball valve 57, and a sixth manual ball valve 58.

[0044] Furthermore, in an embodiment not shown in the figure of the present application, the intelligent bridging device also includes a control module, which is connected to the humidity transmitter 56 by signal, so that the control module automatically adjusts the flow and pressure of the drying gas according to the ambient humidity information monitored in real time by the humidity transmitter 56.

[0045] Specifically, the secondary evaporation and filtration module 50 interfaces with the drying and nitrogen injection equipment, ensuring overall drying and nitrogen injection pressure maintenance after the liquid-cooled cabinet completes a series of operations, including constant-pressure liquid injection. The gas stream passes through a fifth manual ball valve 52 and a fifth electric ball valve 53 before entering a third filter 54. The ternary separation and collection module within this third filter 54 separates and processes the gas. However, the gas may have substandard humidity at this point, as the drying and nitrogen injection equipment requires a completely dry gas environment. Therefore, a filter-evaporator 55 is provided to perform secondary filtration and evaporation on the gas stream. This is monitored via a humidity transmitter 56, which measures the humidity in the enclosed duct space in real time and feeds it back to the control module for closed-loop humidity regulation. The gas stream ultimately passes through a sixth electric ball valve 57 and a sixth manual ball valve 58, exits the flow confluence assembly 20, and flows into the liquid-cooled cabinet through its docking port (i.e., cabinet port 24).

[0046] like Figure 1 and Figure 2 As shown, the inlet of the gas path analysis and pressure maintaining module 30, the inlet of the flow pressure monitoring module 40, and the inlet of the secondary evaporation and filtration module 50 are located on the first surface of the box 10; the cabinet interface 24 is located on the second surface of the box 10, and the first surface and the second surface are arranged opposite to each other.

[0047] It should be noted that, in the present application, the first surface is the front door panel 14 side of the box body 10 , and the second surface is the rear door panel 15 side of the box body 10 .

[0048] like Figure 1 and Figure 2 As shown, a plurality of status indicator lights 17 are provided on at least one surface of the box body 10, at least one of the plurality of status indicator lights 17 monitors the status of the control module of the intelligent bridging device, and the remaining status indicator lights 17 monitor the status of at least the gas path analysis and pressure maintaining module 30, the flow pressure monitoring module 40, and the secondary evaporation and filtration module 50 respectively.

[0049] Furthermore, the intelligent bridging device also includes a water receiving tray, which is arranged in the accommodating cavity and located below the multiple liquid cooling units to at least receive liquid leakage caused by abnormalities in the liquid pipe 41 of the flow pressure monitoring module 40.

[0050] According to another aspect of the present application, an intelligent bridging method is also provided, including docking the entrance of the liquid-cooled cabinet with the cabinet interface 24 of the intelligent bridging device; starting the intelligent bridging device, and obtaining at least the equipment model and rated pressure of the liquid-cooled cabinet to identify the test configuration of the liquid-cooled cabinet for generating an automatic test program; starting the secondary evaporation and filtration module 50 of the intelligent bridging device, and introducing ultra-dry nitrogen into the secondary evaporation and filtration module 50 through the drying and nitrogen injection system; performing sealing verification through the gas path analysis and pressure maintaining module 30 of the intelligent bridging device, and starting the automatic test program after verification that there is no abnormality; according to the automatic test program, the liquid-cooled cabinet is switched and connected with the gas path analysis and pressure maintaining module 30, the flow and pressure monitoring module 40 of the intelligent bridging device, and the secondary evaporation and filtration module 50 in turn to perform matching tests of helium detection and pressure maintaining, constant pressure liquid injection, and drying nitrogen injection in turn; after completing the matching tests of helium detection and pressure maintaining, constant pressure liquid injection, and drying nitrogen injection in turn, the connection between the liquid cooling cabinet and the cabinet interface 24 is manually released.

[0051] Specifically, refer to Figure 8 As shown:

[0052] 1. Manually push the liquid cooling cabinet into place and connect the liquid cooling cabinet to the intelligent bridge device;

[0053] 2. Start the intelligent bridge device and scan the RFID tag of the liquid cooling cabinet to obtain parameters such as the equipment model and rated pressure (compatible with ISO / IEC 15963 standards) to identify its test configuration. The device then retrieves the historical test database in the cloud, compares it with the seal life prediction model, and dynamically generates customized test thresholds. Finally, after integration through internal programs, an automatic test program is generated on the intelligent device.

[0054] 3. Multimodal pre-treatment self-test. Start the secondary evaporation and filtration module 50 and introduce ultra-dry nitrogen (dew point ≤ -70°C) to purge the pipeline for 30 seconds to remove residual liquid and particulate matter. Baseline calibration: The flow and pressure sensor monitoring module performs zero point calibration and establishes a pressure-flow baseline curve through its own sensor array (range 0-2MPa, accuracy ±0.1%FS).

[0055] 4. Multi-stage sealing verification. The system is dynamically pressurized, and the gas path analysis and pressure maintenance module 30 adopts a segmented pressure increase strategy (0→0.5MPa→1.2MPa, gradient interval 60 seconds), and a mass spectrometer is used to detect the helium leakage rate (sensitivity 10 9 Pa·m³ / s), combined with the digital twin model to compare the theoretical pressure decay curve, triggering a level 3 alarm when the measured value deviates by >5%. After verification that there is no abnormality, the normal test procedure is initiated;

[0056] 5. The test is automatically performed according to the automatic test program. The equipment automatically switches the connection between the liquid cooling cabinet and each liquid cooling unit node in turn, and performs matching tests such as helium detection and pressure maintenance, constant pressure liquid injection, drying and nitrogen injection;

[0057] 6. After the test is completed, manually disconnect the cabinet.

[0058] like Figure 7 As shown in the figure, the principle schematic diagram of the intelligent bridging device of the liquid cooling cabinet and multiple liquid cooling units is shown.
