Description

Technical Field

[0001] This application relates to the field of mechanical component testing technology, and in particular to a test device for the insertion and removal sealing performance of a liquid-cooled quick connector. Background Technology

[0002] As a key component in liquid cooling systems, the reliability, sealing performance, and service life of liquid-cooled quick-connect couplings directly affect the stable operation of the entire system. Current technologies for testing the insertion and removal sealing performance of liquid-cooled quick-connect couplings typically only achieve static sealing performance testing. These methods mainly involve filling the coupling with gas or liquid at a certain pressure in the mated state, and judging its static sealing effect by observing the pressure drop or directly measuring the leakage through precision instruments. However, such methods can only simulate the steady-state conditions after the coupling is connected and cannot evaluate its dynamic sealing performance during insertion and removal.

[0003] In practical applications, the dynamic insertion and removal process of liquid-cooled quick connectors is a high-risk factor for airtightness failure. Although there is a demand in the industry for individual testing of air ingress during insertion and removal, current testing methods are fragmented and usually require offline testing with separate dedicated equipment. This testing method not only leads to cumbersome procedures and low testing efficiency, but more importantly, due to the fragmented nature of the testing, it is difficult to collect and establish the correlation data between "insertion and removal times" and "air ingress" in real time and synchronously while the insertion and removal actions are taking place. Therefore, it is impossible to accurately assess the dynamic sealing performance degradation trend of the connector throughout its entire lifespan. Summary of the Invention

These mechanisms work collaboratively under the unified control of the main electrical control box, effectively solving the problems of cumbersome traditional testing processes and reliance on multiple devices, thus significantly improving testing efficiency. In particular, this insertion and removal sealing performance testing equipment can not only simulate driving the liquid-cooled quick-connect fitting through conventional insertion and removal operations to test its static sealing performance, but also deliver liquid to the liquid-cooled quick-connect fitting in real time during dynamic insertion and removal.

Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In the description of this application, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0022] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Please see Figure 1 and Figure 2As shown, in one embodiment, this application provides a test device 1 for the insertion and removal sealing performance of a liquid-cooled quick connector. The liquid-cooled quick connector includes a male quick connector 2 and a female quick connector 3. The test device 1 includes a frame 10, a main control box 20, a first insertion and removal test mechanism 30, and a second insertion and removal test mechanism 40. The main control box 20 is installed in the frame 10 and is electrically connected to both the first insertion and removal test mechanism 30 and the second insertion and removal test mechanism 40. The first insertion and removal test mechanism 30 is installed in the frame 10 and is configured to, under the control of the main control box 20, simulate the insertion and removal operation of the corresponding male quick connector 2 and female quick connector 3, and deliver a first liquid with a preset pressure value to the male quick connector 2 and female quick connector 3 in the inserted state. By measuring the amount of liquid leakage of the corresponding liquid-cooled quick connector in the inserted state, the static sealing performance of the corresponding liquid-cooled quick connector is tested. The second insertion and removal test mechanism 40 is installed in the equipment frame 10. The second insertion and removal test mechanism 40 is configured to simulate the insertion and removal operation of the corresponding quick connector male head 2 and quick connector female head 3 under the control of the main electrical control box 20, and to deliver a second liquid to the quick connector male head 2 and quick connector female head 3 during the insertion and removal process. Then, by measuring the air content mixed in the second liquid during the insertion and removal process, the dynamic sealing performance of the corresponding liquid-cooled quick connector is tested.

[0024] It should be noted that the liquid-cooled quick-connect fitting insertion and removal sealing performance testing equipment 1 of this application embodiment is mainly applied to the research and development verification, factory quality inspection, or life testing scenarios of liquid-cooled quick-connect fitting products in the fields of liquid-cooled servers, energy storage equipment, and new energy vehicles. The first insertion and removal testing mechanism 30 mentioned above is specifically used to simulate the connection state of the liquid-cooled quick-connect fitting during long-term use. By injecting pressurized liquid into the fitting after insertion and removal and monitoring the leakage, its static sealing performance is evaluated. The second insertion and removal testing mechanism 40 mentioned above is specifically used to simulate the repeated insertion and removal process of the liquid-cooled quick-connect fitting in actual operation. By measuring the amount of air introduced by each insertion and removal action online, its dynamic sealing performance and service life are evaluated. The main electrical control box 20 mentioned above can be a programmable logic controller (PLC) or an industrial computer. Its internal preset or editable test control program is used to accurately coordinate and control the action sequence and operating parameters of each functional component in each insertion and removal testing mechanism (i.e., the first insertion and removal testing mechanism 30 and the second insertion and removal testing mechanism 40) in real time, so as to realize the automated testing process of each insertion and removal testing mechanism.

[0025] In this way, the liquid-cooled quick connector insertion and removal sealing performance testing equipment 1 of this application embodiment, through integrated structural design, integrates the first insertion and removal testing mechanism 30 and the second insertion and removal testing mechanism 40 on the same equipment frame 10, and they work together under the unified control of the main electrical control box 20. This effectively solves the problem of cumbersome traditional testing processes and reliance on multiple devices, significantly improving testing efficiency. In particular, this insertion and removal sealing performance testing equipment 1 can not only simulate driving the liquid-cooled quick connector to perform conventional insertion and removal operations to test its static sealing performance, but also deliver liquid to the liquid-cooled quick connector in real time during dynamic insertion and removal. By accurately measuring the air content mixed into the liquid during insertion and removal, it simultaneously collects and establishes the correlation data between "insertion and removal times" and "air mixing amount". This innovative design fills the gap in the existing technology, which can only evaluate the static sealing effect and cannot capture the sealing performance decay during dynamic insertion and removal. It provides key data support for comprehensively evaluating the dynamic sealing reliability of the liquid-cooled quick connector throughout its entire life cycle, thereby ensuring the overall operational stability of the liquid cooling heat dissipation system.

[0026] In some examples, such as Figure 1 and Figure 2 As shown, both the first insertion / removal test mechanism 30 and the second insertion / removal test mechanism 40 include a fixed mold assembly (i.e., the first fixed mold assembly 31 or the second fixed mold assembly 41) and an insertion / removal drive assembly (i.e., the first insertion / removal drive assembly 32 or the second insertion / removal drive assembly 42). The fixed mold assembly is configured to clamp and fix the corresponding quick-connect female head 3. The insertion / removal drive assembly is positioned opposite to the corresponding fixed mold assembly and is configured to clamp and fix the corresponding quick-connect male head 2, and drive the corresponding quick-connect male head 2 to move along the X-axis direction, so that the corresponding quick-connect male head 2 and the corresponding quick-connect female head 3 can perform corresponding insertion / removal actions. The X-axis direction is the axial direction of the quick-connect male head 2 (i.e., the axial direction of the quick-connect male head 2). Figure 2 (In the direction indicated by the middle arrow X). Thus, the first insertion / removal test mechanism 30 and the second insertion / removal test mechanism 40 respectively fix the quick-connect male head 2 and the quick-connect female head 3 to the corresponding components, and the insertion / removal drive component precisely drives the quick-connect male head 2 to move axially. This can accurately simulate the insertion / removal process of the corresponding liquid-cooled quick-connect in actual use, ensuring the stability and repeatability of the insertion / removal action, and providing a reliable basis for subsequent insertion / removal force measurement and life test.

[0027] It should be noted that the relative positions of the fixed mold component and the plug-in drive component in this example can be adjusted according to testing requirements to accommodate liquid-cooled quick connectors of different specifications and sizes, thereby improving the versatility and adaptability of the equipment.

[0028] In some examples, such as Figure 1 and Figure 2As shown, the insertion and removal sealing performance testing equipment 1 also includes a liquid replenishment tank 50, and the first insertion and removal testing mechanism 30 also includes a first testing component 33. The first testing component 33 includes a first delivery pipeline 331, a pressure reducing valve 332, a pressure sensor 333, and a first flow calibration column 334. The first delivery pipeline 331 connects the liquid replenishment tank 50 to the corresponding liquid-cooled quick connector. The first delivery pipeline 331 is configured to deliver a first liquid with a preset pressure value to the male and female quick connectors 2 and 3 in the inserted state. The pressure reducing valve 332 is installed in the first delivery pipeline 331 and is configured to adjust and stabilize the liquid pressure in the corresponding first delivery pipeline 331 to the preset pressure value. The pressure sensor 333 is installed in the first delivery pipeline 331 and is configured to monitor the liquid pressure in the corresponding first delivery pipeline 331 in real time. The first flow calibration column 334 is installed in the first delivery pipeline 331 and is configured to record changes in the liquid flow rate in the first delivery pipeline 331. The main control box 20 is also electrically connected to the pressure reducing valve 332, the pressure sensor 333, and the first flow calibration column 334. Furthermore, the main control box 20 is configured to combine the data from the pressure sensor 333 and the first flow calibration column 334 to comprehensively determine the liquid leakage of the corresponding liquid-cooled quick-connect fitting in the mated state, thereby testing the static sealing performance of the corresponding liquid-cooled quick-connect fitting. Thus, the pressure closed-loop control system formed by the pressure reducing valve 332 and the pressure sensor 333 ensures the accuracy and stability of the test pressure. By analyzing the flow changes recorded by the first flow calibration column 334 and combining this with a stable pressure environment, the main control box 20 can accurately determine whether leakage exists and the magnitude of the leakage, achieving precise quantitative testing of static sealing performance.

[0029] It should be noted that, to achieve the electrical connection between the first flow calibration column 334 and the main electrical control box 20 in this example, a flow sensor can be integrated internally or externally connected to the first flow calibration column 334. This flow sensor converts the corresponding flow signal into an electrical signal, which is then transmitted to the main electrical control box 20. Based on the received electrical signal and a preset algorithm or calibration curve, the main electrical control box 20 can calculate the specific liquid leakage amount. Furthermore, the first flow calibration column 334 itself can also be a graduated transparent glass tube with an internal float, facilitating visual observation and manual recording by the operator.

[0030] In some examples, such as Figure 1 and Figure 2As shown, the second insertion / removal test mechanism 40 also includes a second test component 43, which includes a second delivery pipeline 431, a second flow calibration column 432, and a third flow calibration column 433. The second delivery pipeline 431 connects the liquid replenishment tank 50 to the corresponding liquid-cooled quick connector, and is configured to deliver a second liquid to the male and female quick connectors 2 and 3 during the insertion / removal process. The second flow calibration column 432 is located at the beginning of the second delivery pipeline 431 and is configured to record the flow rate of liquid flowing from the second delivery pipeline 431 into the corresponding liquid-cooled quick connector. The third flow calibration column 433 is located at the end of the second delivery pipeline 431 and is configured to record the flow rate of liquid flowing back from the corresponding liquid-cooled quick connector into the second delivery pipeline 431. The main control box 20 is also electrically connected to the second flow calibration column 432 and the third flow calibration column 433, respectively. The main control box 20 is also configured to combine the data from the second and third flow calibration columns 432 and 433 to measure the air content mixed into the second liquid during insertion and removal, thereby testing the dynamic sealing performance of the corresponding liquid-cooled quick-connect fitting. Thus, by setting the second and third flow calibration columns 432 and 433 to accurately measure the liquid flow rate into and out of the liquid-cooled quick-connect fitting, the main control box 20 can compare the difference between the two values ​​in real time. When air is mixed into the quick-connect fitting during insertion and removal due to valve core movement or seal failure, the liquid in the pipeline will be replaced by air, making the liquid volume at the outflow end smaller than that at the inflow end. Based on this volume difference, the air content introduced in each insertion and removal action can be quantitatively calculated. The smaller this air content value, the better the sealing performance of the liquid-cooled quick-connect fitting during dynamic insertion and removal. Compared to traditional testing methods, this online measurement method eliminates the need for additional airtightness testing equipment. It allows for the simultaneous acquisition of dynamic sealing performance data during mechanical insertion and removal life testing, significantly simplifying the testing process and improving efficiency. Furthermore, by correlating the number of insertions and removals with the amount of air mixed in, it provides accurate data support for analyzing the sealing performance degradation patterns of liquid-cooled quick connectors and assessing their true service life.

[0031] It should be noted that, in order to achieve the electrical connection between the second flow calibration column 432 and the third flow calibration column 433 in this example and the main electrical control box 20, flow sensors can be integrated internally or externally connected to the second flow calibration column 432 and the third flow calibration column 433. These flow sensors convert the corresponding flow signals into electrical signals and transmit them to the main electrical control box 20. Furthermore, the second flow calibration column 432 and the third flow calibration column 433 themselves can also be transparent glass tubes with graduations and internal floats, facilitating visual observation and manual recording by operators.

[0032] In some examples, such as Figure 1 and Figure 2As shown, the fixed mold assembly (i.e., the first fixed mold assembly 31 or the second fixed mold assembly 41) includes a fixed positioning seat (i.e., the first fixed positioning seat 311 or the second fixed positioning seat 411). A first positioning groove is provided at the end of the fixed positioning seat facing the plug-in drive assembly. The first positioning groove is configured to clamp and fix the quick-connect female head 3. The plug-in drive assembly (i.e., the first plug-in drive assembly 32 or the second plug-in drive assembly 42) includes a movable positioning seat (i.e., the first movable positioning seat 121 or the second movable positioning seat 421) and a plug-in drive structure (i.e., the first plug-in drive structure 122 or the second plug-in drive structure 422) that drives the movable positioning seat to move along the X-axis. A second positioning groove is provided at the end of the movable positioning seat facing the fixed mold assembly. The second positioning groove is configured to clamp and fix the quick-connect male head 2. Thus, by setting a dedicated positioning groove (i.e., the first positioning groove or the second positioning groove) to clamp and fix the corresponding quick-connect female head 3 or quick-connect male head 2, the positional stability and repeatability of the liquid-cooled quick-connect during testing can be ensured, avoiding test errors caused by improper clamping. Furthermore, the shape of the positioning groove (i.e., the first positioning groove or the second positioning groove) can be customized according to the shape of the corresponding quick connector female head 3 or quick connector male head 2 to meet the insertion and removal test requirements of liquid-cooled quick connectors of different types and specifications.

[0033] It should be noted that, in this example, the first and second positioning slots may be further equipped with elastic clamping mechanisms or quick clamps to facilitate the quick assembly and disassembly of the corresponding quick connector female head 3 or quick connector male head 2, thereby further improving the efficiency of the corresponding insertion and removal tests.

[0034] In some examples, such as Figure 1 and Figure 2 As shown, the insertion / removal drive structure includes a thrust sensor, a ball screw, an insertion / removal moving seat that engages with the ball screw's rolling helix, and a servo motor that drives the ball screw to rotate, causing the insertion / removal moving seat to move back and forth relative to the ball screw. A movable positioning seat is fixed on the insertion / removal moving seat. The servo motor and the thrust sensor are electrically connected to the main control box 20. The main control box 20 is configured to collect the axial force value generated by the insertion / removal action through the thrust sensor. When the axial force value is less than or equal to a preset force threshold, the axial force value is obtained as the insertion / removal force parameter for a corresponding set of liquid-cooled quick connectors. When the axial force value is greater than the preset force threshold, the corresponding servo motor is controlled to stop the corresponding insertion / removal action. Thus, by using a servo motor to drive the ball screw, high-precision and high-stability linear motion can be achieved, ensuring the smoothness of the insertion / removal action and the accuracy of position control. The thrust sensor can monitor the axial force generated during the insertion / removal process in real time, providing accurate data for obtaining the insertion / removal force parameters. Meanwhile, when abnormally high insertion and extraction force is detected, the main electrical control box 20 can promptly control the servo motor to stop operating, effectively protecting the quick connector and test equipment from damage.

[0035] It should be noted that the insertion / removal drive structure in this example can also adopt other forms such as linear motors, cylinders with guide rails, etc., but the combination of servo motors and ball screws has advantages in terms of precision and controllability. The preset force threshold in this example can be set according to the specifications and testing requirements of the liquid-cooled quick connector to adapt to the testing needs of different products. The axial force data collected by the thrust sensor in this example can be recorded and stored in real time for subsequent insertion / removal force analysis and life assessment. In addition, the thrust sensor in this example can preferably be installed in the second positioning slot in actual layout to more directly sense the axial load transmitted to the male quick connector 2 during the insertion / removal process.

[0036] In some examples, such as Figure 1 and Figure 2 As shown, the first insertion / removal test mechanism 30 and / or the second insertion / removal test mechanism 40 also include an offset simulation component (not shown). The offset simulation component is driven to at least one of the fixed positioning seat and the movable positioning seat. The offset simulation component is configured to drive at least one of the fixed positioning seat and the movable positioning seat to perform offset movement in at least one direction to simulate the relative position offset between the quick-connect male connector 2 and the quick-connect female connector 3 in a non-aligned state. In this way, by setting the offset simulation component, it is possible to simulate non-ideal alignment states such as axial offset and angular deviation that may occur during the actual installation and use of the liquid-cooled quick-connect, making the test conditions closer to the actual working conditions, thereby more comprehensively evaluating the insertion / removal sealing performance and adaptability of the liquid-cooled quick-connect under complex conditions.

[0037] It should be noted that the offset simulation component can be set with multiple degrees of freedom for offset motion, including linear offset and angular offset, to simulate various possible misalignment situations. The offset amount can be set according to the actual application scenario to test the insertion and extraction performance of the liquid-cooled quick connector under different offset levels.

[0038] In some examples, such as Figure 1 and Figure 2 As shown, the offset simulation component includes a Y-axis offset structure and a Y-axis offset sensor. The Y-axis offset structure is driven by a fixed positioning seat or a movable positioning seat to drive the fixed positioning seat or the movable positioning seat to move in the Y-axis direction (i.e., Figure 2The offset movement (in the direction indicated by the arrow Y) causes a first preset positional offset between the male quick-connect connector 2 and the female quick-connect connector 3 in the Y-axis direction, which is perpendicular to the X-axis direction. The Y-axis offset structure and the Y-axis offset sensor are electrically connected to the main control box 20. The Y-axis offset sensor is configured to provide real-time feedback of the first actual value of the positional offset between the male quick-connect connector 2 and the female quick-connect connector 3 in the Y-axis direction. The main control box 20 is configured to perform closed-loop control of the Y-axis offset structure based on the first actual value and the first preset value to ensure that the Y-axis offset error is within the first preset accuracy range. Thus, by setting the Y-axis offset structure and the Y-axis offset sensor, and employing closed-loop control, the offset in the Y-axis direction can be precisely controlled, ensuring the accuracy and repeatability of the offset. This accurately simulates the misalignment of the liquid-cooled quick-connect connector in the Y-axis direction, providing reliable offset conditions for insertion and removal performance testing.

[0039] It should be noted that the first preset accuracy range in this example can be set according to the test requirements, and is usually controlled within ±0.01mm to ensure the accuracy of offset control. Furthermore, the Y-axis offset structure in this example can be a conventional precision linear module or a piezoelectric ceramic actuator.

[0040] In some examples, such as Figure 1 and Figure 2 As shown, the offset simulation component includes a Z-axis offset structure and a Z-axis offset sensor. The Z-axis offset structure is driven by a fixed or movable positioning seat to drive the fixed or movable positioning seat to move in the Z-axis direction (i.e., Figure 2 The offset movement (in the direction indicated by the arrow Z) causes a second preset positional offset between the male quick-connect connector 2 and the female quick-connect connector 3 in the Z-axis direction, which is perpendicular to the plane containing both the X and Y axes. The Z-axis offset structure and the Z-axis offset sensor are electrically connected to the main control box 20. The Z-axis offset sensor is configured to provide real-time feedback of the second actual value of the positional offset between the male quick-connect connector 2 and the female quick-connect connector 3 in the Z-axis direction. The main control box 20 is configured to perform closed-loop control of the Z-axis offset structure based on the second actual value and the second preset value to ensure that the Z-axis offset error is within the second preset accuracy range. Thus, by setting up the Z-axis offset structure and the Z-axis offset sensor, and employing closed-loop control, the offset in the Z-axis direction can be precisely controlled, ensuring the accuracy and repeatability of the offset. This accurately simulates the misalignment of the liquid-cooled quick-connect connector in the Z-axis direction, providing more comprehensive offset conditions for insertion and removal performance testing.

[0041] It should be noted that the second preset accuracy range in this example can also be set according to test requirements, and is usually controlled within ±0.01mm to maintain high precision in offset control. Furthermore, the Z-axis offset structure in this example can be a conventional precision linear module or a piezoelectric ceramic actuator.

[0042] In some examples, such as Figure 1 and Figure 2 As shown, the offset simulation component includes a rotational offset structure and an angle offset sensor. The rotational offset structure is driven by a fixed or movable positioning seat to rotate and offset, thereby creating a third preset angle offset between the male quick-connect connector 2 and the female quick-connect connector 3. The rotational offset structure and the angle offset sensor are electrically connected to the main control box 20. The angle offset sensor is configured to provide real-time feedback of the third actual value of the angle offset between the male quick-connect connector 2 and the female quick-connect connector 3. The main control box 20 is configured to perform closed-loop control of the rotational offset structure based on the third actual value and the third preset value to ensure that the angle offset error is within the third preset accuracy range. Thus, by setting up the rotational offset structure and the angle offset sensor, and adopting a closed-loop control method, the angle offset can be precisely controlled, simulating the angle misalignment that may occur in liquid-cooled quick-connect connectors under installation deviations or vibration environments. This allows for a more comprehensive evaluation of the insertion and removal performance and sealing reliability of liquid-cooled quick-connect connectors under complex working conditions.

[0043] It should be noted that the third preset accuracy range in this example can be set according to the test requirements, and is usually controlled within ±0.1° to ensure the accuracy of angular offset control. Furthermore, the rotational offset structure in this example can specifically be a conventional precision rotary table or a worm gear mechanism.

[0044] In some examples, such as Figure 1 and Figure 2As shown, the first insertion / removal test mechanism 30 and / or the second insertion / removal test mechanism 40 further include a latch unlocking mechanism (i.e., the first latch unlocking mechanism 34 or the second latch unlocking mechanism 44). The latch unlocking mechanism includes two latch clamping blocks (i.e., the first latch clamping block 341 or the second latch clamping block 441), a clamping drive cylinder (i.e., the first clamping drive cylinder 342 or the second latch clamping drive cylinder) for driving the two latch clamping blocks to close or open, and an unlocking drive cylinder (i.e., the first unlocking drive cylinder 343 or the second unlocking drive cylinder 443) for driving the two latch clamping blocks to move along the X-axis. The two latch clamping blocks are arranged opposite to each other on both sides of the latch of the quick connector female head 3 fixed to the corresponding fixed mold assembly. In this way, by setting the latch unlocking mechanism, automated insertion / removal testing of liquid-cooled quick connectors with self-locking latches can be achieved. During the insertion and removal process, when it is necessary to separate the male quick-connect connector 2 and the female quick-connect connector 3, the clamping drive cylinder drives the two latching blocks to close, clamping the latches on the female quick-connect connector 3. Then, the unlocking drive cylinder drives the two latching blocks to move along the X-axis (i.e., away from the male quick-connect connector 2), thereby simulating the action of manually pressing or pulling the latches and achieving automatic unlocking. This realizes fully automatic testing of liquid-cooled quick-connect connectors with locking mechanisms, eliminating the need for manual intervention and improving testing efficiency and automation level.

[0045] It should be noted that the shape of the clip-holding block in this example can be customized according to the specific structure of the quick-connect female head 3 clip to ensure reliable clamping and prevent damage to the clip. The timing of the clamping drive cylinder and the unlocking drive cylinder is precisely controlled by the main electrical control box 20 to simulate the real unlocking process.
