[0028] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] As Figure 1 shown, an integrated test platform for a self-sealing quick connector of a liquid cooling system of the present invention includes a gas pressure module 1, a liquid circulation pressure module 2, and a test motion tooling module 3. The self-sealing quick connector 35 includes an upper half connector 37 and a lower half connector 36. The gas pressure module 1 includes a gas supply and pressure regulating assembly and an airtightness detection assembly. The liquid circulation pressure module 2 includes a liquid storage tank 18 and a flow-through test assembly. The test motion tooling module 3 includes a test chamber 29 and a servo up-and-down insertion actuator 30. The servo up-and-down insertion actuator 30 is connected to the test chamber 29. The lower half connector 36 is fixed inside the test chamber 29. The upper half connector 37 is connected to the servo up-and-down insertion actuator 30 and aligned with the lower half connector 36. The lower half connector 36 is provided with a liquid inlet 38, and the upper half connector 37 is provided with a liquid return port 39. The liquid inlet paths of the flow-through test assembly are respectively connected to the liquid storage tank 18 and the liquid inlet 38 of the lower half connector 36, and the liquid return paths of the flow-through test assembly are respectively connected to the liquid return port 39 of the upper half connector 37 and the liquid storage tank 18. The air inlet end of the gas supply and pressure regulating assembly is connected to a gas source 4, and the air outlet end of the gas supply and pressure regulating assembly is respectively butted against the upper part of the liquid level of the liquid storage tank 18 and the air inlet end of the airtightness detection assembly. The air outlet end of the airtightness detection assembly is respectively butted against the liquid inlet 38 of the lower half connector 36 and the liquid return port 39 of the upper half connector 37.

[0030] The gas pressure module 1 provides a stable driving gas for the system valve action and provides pressure output for the pressure resistance, overall airtightness, and split airtightness. The liquid circulation pressure module 2 provides a liquid circulation with adjustable flow rate for the system. The test motion tooling module 3 is mainly used for the up-and-down insertion of the lower half connector 36 and the upper half connector 37.

[0031] The liquid storage tank 18 is used to provide a circulating liquid source when performing flow rate and pressure resistance tests on the liquid circulation pressure module 2. A liquid level gauge 19 is provided on the liquid storage tank 18 for real-time monitoring of the liquid level height inside the liquid storage tank 18. The servo up-and-down insertion actuator 30 adopts a servo up-and-down insertion actuator 30, which can control the forward or reverse rotation of the servo up-and-down insertion actuator 30 through an electric servo, thereby controlling the rise or fall of the upper half connector 37 relative to the lower half connector 36, and further completing the operation of pulling off or inserting the self-sealing quick connector 35. During the entire test process, the self-sealing quick connector 35 is all completed inside the test chamber 29. When flow rate and pressure resistance tests need to be performed, the self-sealing quick connector 35 is connected to the liquid circulation pressure module 2. When airtightness tests need to be performed, the self-sealing quick connector 35 is connected to the gas pressure module 1.

[0032] As Figure 2As shown in the figure, the test motion tooling module 3 further includes a displacement sensor 31, a force sensor 32, a fixed seat 33, a planar slide 34, a servo horizontal pressing actuator 40, and a servo horizontal rotating actuator 41. The fixed seat 33 is installed at the bottom of the test chamber 29. The planar slide 34 is connected to the fixed seat 33. The lower half joint 36 is fixed to the planar slide 34. The displacement sensor 31 and the force sensor 32 are connected to the servo up and down insertion actuator 30. The servo horizontal pressing actuator 40 and the servo horizontal rotating actuator 41 are installed on the planar slide 34. By adjusting the forward and reverse rotation of the servo up and down insertion actuator 30, the insertion or separation of the lower half joint 36 and the upper half joint 37 is controlled. The insertion force test is carried out through the force sensor 32, and the displacement of the upper half joint 37 being pressed and separated is monitored through the displacement sensor 31. The planar slide 34 realizes the vertical alignment of the upper half joint 37 and the lower half joint 36. The planar slide is internally provided with a rolling bearing 42 and a locking mechanism 43. Before installing the sample, the upper and lower parts can be aligned and locked to prevent the eccentric connection of the upper half joint 37 and the lower half joint 36, resulting in a large deviation between the test result and the design. For the pressing and rotation life test of the lower half joint 36 with a pressing buckle and a rotating buckle in the mating part, the servo horizontal pressing actuator 40 and the servo horizontal rotating actuator 41 for the pressing life test can be installed on the planar slide 34.

[0033] The flow test assembly includes a liquid storage stop valve 20, a variable frequency pump 21, a flow meter 22, a liquid pressure gauge 23, an inlet liquid stop valve 25, a return liquid stop valve 26, a second differential pressure gauge 27, and a bypass valve 28. The liquid outlet of the liquid storage tank 18, the liquid storage stop valve 20, the variable frequency pump 21, the flow meter 22, the liquid pressure gauge 23, the inlet liquid stop valve 25, and the liquid inlet 38 of the lower half joint 36 are sequentially connected through a joint pipeline to form an outlet liquid channel. The liquid return port 39 of the upper half joint 37, the return liquid stop valve 26, and the liquid return port 39 of the liquid storage tank 18 are sequentially connected through a joint pipeline to form a return liquid channel. The two ends of the second differential pressure gauge 27 are respectively connected to the joint pipeline at the liquid inlet 38 of the lower half joint 36 and the joint pipeline at the liquid return port 39 of the upper half joint 37. The two ends of the bypass valve 28 are respectively communicated with the joint pipelines of the outlet liquid channel and the return liquid channel.

[0034] The liquid storage stop valve 20 is used to control the opening and closing of the liquid storage tank 18. By adjusting the operating speed of the variable-frequency pump 21, the flow rate of the sample flowing through the self-sealing quick connector 35 can be adjusted to conduct a flow capacity test. The flowmeter 22 can measure the flow rate value passing through the self-sealing quick connector 35; the second differential pressure gauge 27 is used to measure the flow resistance of the liquid after flowing through the sample self-sealing quick connector 35; the liquid pressure gauge 23 can measure different water pressure values when flowing through the self-sealing quick connector 35; when the lower half joint 36 and the upper half joint 37 of the self-sealing quick connector 35 are inserted, the loop is connected, and the liquid forms a circulation path with the liquid storage tank 18 after passing through the self-sealing quick connector 35. When the lower half joint 36 and the upper half joint 37 of the self-sealing quick connector 35 are pulled off, the self-sealing quick connector 35 is disconnected. At this time, the inlet stop valve 25 and the return stop valve 26 are closed, and the liquid forms a circulation path with the liquid storage tank 18 through the bypass valve 28.

[0035] The flow test assembly further includes a purge valve 24. The purge valve 24 is connected to the joint pipeline of the liquid outlet channel, and the purge valve 24 is externally connected to the air source 4. After the flow test is completed or when it is necessary to drain and dry the liquid in the joint pipeline, air can be blown into the liquid circulation pressure module 2 through the purge valve 24 to drain the liquid in the pipe through the air flow.

[0036] The air supply pressure regulating assembly includes a ball valve 5, a gas filter 6, a pressure regulating valve 7, and a second gas circuit stop valve 8. The air source 4, the ball valve 5, the gas filter 6, the pressure regulating valve 7, the second gas circuit stop valve 8, and the liquid storage tank 18 are sequentially connected through joint pipelines.

[0037] Through the gas pressure module 1, the electric pressure regulating valve 7 and the gas circuit stop valve act on the liquid level of the liquid storage tank 18 in the liquid circulation pressure module 2. By adjusting the gas pressure output of the electric pressure regulating valve 7, the pressure of the internal circulating liquid in the liquid circulation pressure module 2 can be indirectly controlled, and the pressure resistance test of the sample self-sealing quick connector 35 can be carried out.

[0038] The airtight detection component includes a first air path cut-off valve 9, a gas pressure gauge 10, a first leak detection valve 11, a second leak detection valve 12, a first differential pressure gauge 17, a first gas cut-off valve 15, a second gas cut-off valve 16, and a standard container 13. The intake end of the first air path cut-off valve 9 is connected to the output end of the pressure regulating valve 7 through a connecting pipe. The outlet end of the first air path cut-off valve 9 is connected to one ends of the first leak detection valve 11 and the second leak detection valve 12 respectively through a connecting pipe. The other end of the first leak detection valve 11 is connected to the standard container 13 through a connecting pipe. The other end of the second leak detection valve 12 is connected to one ends of the first gas cut-off valve 15 and the second gas cut-off valve 16 respectively through a connecting pipe. The other end of the first gas cut-off valve 15 is connected to the liquid inlet 38 of the lower half joint 36. The other end of the second gas cut-off valve 16 is connected to the liquid return port 39 of the upper half joint 37. The gas pressure gauge 10 is connected to the connecting pipe at the outlet end of the first air path cut-off valve 9. One end of the first differential pressure gauge 17 is connected to the standard container 13, and the other end of the first differential pressure gauge 17 is connected to the first gas cut-off valve 15 and the second gas cut-off valve 16 respectively.

[0039] The first air path cut-off valve 9 is used to control the connection or disconnection between the entire airtight detection component and the gas source 4. The first leak detection valve 11 and the second leak detection valve 12 are used to pressurize the standard container 13 and the self-sealing quick connector 35 respectively. The first gas cut-off valve 15 and the second gas cut-off valve 16 are used to control the gas connection or disconnection of the lower half joint 36 and the upper half joint 37 respectively. The first differential pressure gauge 17 is used to measure the relative pressure difference between the standard container 13 and the self-sealing quick connector 35 after pressurization. The gas pressure gauge 10 is used to detect the gas pressure value during pressurization.

[0040] The test process of the self-sealing quick connector comprehensive test platform of this liquid cooling system includes the following methods:

[0041] The process of the test motion tooling module 3 performing the insertion force test and the insertion, pressing, and rotation life test on the self-sealing quick connector 35 includes:

[0042] Insertion force test process:

[0043] a1. Adjust the forward rotation of the servo up and down insertion actuator 30. The servo up and down insertion actuator 30 drives the upper half joint 37 to move downward until it is inserted into the lower half joint 36 and pressed tightly. The displacement sensor 31 monitors the insertion distance between the upper half joint 37 and the lower half joint 36, and the force sensor 32 detects the force applied when the self-sealing quick connector 35 is pressed tightly. Before the test, the displacement sensor 31 will perform separate zero calibration and distance measurement of the pressing according to the installation sample of the self-sealing quick connector to determine the reference point for judgment.

[0044] a2. Adjust the servo up-and-down insertion actuator 30 to reverse, and the servo up-and-down insertion actuator 30 drives the upper half joint 37 to separate from the lower half joint 36 and move upward. The displacement sensor 31 monitors the separation distance between the upper half joint 37 and the lower half joint 36.

[0045] Process of the insertion, pressing, and rotation life test:

[0046] a3. The servo horizontal pressing actuator 40 presses the lower half joint 36, the servo up-and-down insertion actuator 30 presses down the upper half joint 37 to insert with the lower half joint 36, the servo horizontal pressing actuator 40 releases, and the servo horizontal rotation actuator 41 rotates and locks, which is counted as one time. The number of times of completing the above actions when the self-sealing quick connector test piece fails is recorded as the insertion, pressing, and rotation life.

[0047] The process of the liquid circulation pressure module 2 performing the flow capacity and flow resistance tests includes:

[0048] b1. When the servo up-and-down insertion actuator 30 drives the upper half joint 37 to insert with the lower half joint 36, the liquid storage tank 18, the lower half joint 36, and the upper half joint 37 form a liquid circulation loop. Adjust the operating speed of the variable-frequency pump 21 to adjust the flow rate through the self-sealing quick connector 35. Measure the flow capacity of the self-sealing quick connector 35 through the flow meter 22, and measure the flow resistance of the liquid flowing through the self-sealing quick connector 35 through the second differential pressure gauge 27. By measuring the pressure loss of the liquid flowing through the inlet and outlet of the self-sealing quick connector 35, the magnitude of the flow resistance can be judged. When the liquid circulation loop is opened, the liquid storage stop valve 20, the inlet stop valve 25, and the return stop valve 26 are opened, and the bypass valve 28 and the purge valve 24 are closed. The liquid flows out from the liquid storage tank 18 and then passes through the liquid storage stop valve 20, the variable-frequency pump 21, the flow meter 22, the liquid pressure gauge 23, the inlet stop valve 25, the lower half joint 36, the upper half joint 37, the return stop valve 26, and the liquid storage tank 18 to form a circulation loop.

[0049] b2. When the servo up-and-down insertion actuator 30 drives the upper half joint 37 to separate from the lower half joint 36, the liquid storage tank 18 forms a circulation path through the bypass valve 28. When this circulation path is opened, the liquid storage stop valve 20 and the bypass valve 28 are in the open state, and the inlet stop valve 25, the return stop valve 26, and the purge valve 24 are in the closed state. The liquid flows out from the liquid storage tank 18 and then passes through the liquid storage stop valve 20, the variable-frequency pump 21, the flow meter 22, the bypass valve 28, and the liquid storage tank 18 to form a circulation path. Both the upper half joint 37 and the lower half joint 36 are equipped with sealing sheets, and they are automatically cut off and sealed when they are separated, and they are conducted when they are inserted. After the self-sealing quick connector is separated, a circulation path is formed through the bypass valve to maintain the flow stability of the circulation system, so as to avoid violent fluctuations in the flow rate caused by the frequent insertion and separation of the self-sealing quick connector.

[0050] The process of conducting a pressure resistance test on the gas supply and pressure regulating component in combination with the liquid circulation pressure module 2 includes:

[0051] When the servo up-and-down insertion actuator 30 drives the upper half joint 37 to be inserted into the lower half joint 36, a liquid circulation loop is formed among the liquid storage tank 18, the lower half joint 36, and the upper half joint 37. The output air pressure of the pressure regulating valve 7 is adjusted to regulate the pressure applied to the liquid level in the liquid storage tank 18, thereby regulating the water pressure flowing through the self-sealing quick connector 35, and the pressure resistance value of the self-sealing quick connector 35 is measured by the liquid pressure gauge 23. When the gas supply and pressure regulating component operates, the ball valve 5 and the second gas circuit cut-off valve 8 are in the open state. Under the operation of the electric pressure regulating valve 7, the gas source 4 acts on the liquid level in the liquid storage tank 18 after passing through the ball valve 5, the gas filter 6, the electric pressure regulating valve 7, and the second gas circuit cut-off valve 8 in sequence.

[0052] The process of conducting the split and overall sealing tests on the self-sealing quick connector 35 by the gas pressure module 1 includes:

[0053] c1. Split sealing test of the lower half joint 36: The servo up-and-down insertion actuator 30 drives the upper half joint 37 to be pulled off from the lower half joint 36. The first leak detection valve 11, the second leak detection valve 12, and the first gas cut-off valve 15 are opened, and the second gas cut-off valve 16 is closed. The gas is pressurized into the standard container 13 through the first leak detection valve 11, and at the same time, the gas is pressurized into the lower half joint 36 through the second leak detection valve 12 and the first gas cut-off valve 15. When the first differential pressure gauge 17 detects that the standard container 13 and the lower half joint 36 reach pressure balance, the first leak detection valve 11 and the second leak detection valve 12 are closed, and the differential pressure between the standard container 13 and the lower half joint 36 is compared through the first differential pressure gauge 17. The user can set the differential pressure threshold for judging air leakage according to requirements. If the differential pressure after the test exceeds the threshold, it is air leakage, otherwise it is not.

[0054] c2. Split sealing test of the upper half joint 37: The servo up-and-down insertion actuator 30 drives the upper half joint 37 to be pulled off from the lower half joint 36. The first leak detection valve 11, the second leak detection valve 12, and the second gas cut-off valve 16 are opened, and the first gas cut-off valve 15 is closed. The gas is pressurized into the standard container 13 through the first leak detection valve 11, and at the same time, the gas is pressurized into the upper half joint 37 through the second leak detection valve 12 and the second gas cut-off valve 16.
