[0033] The present invention discloses a testing device for a server, which is used to solve the technical problem of low utilization rate of testing equipment in the processes of leak detection, gas protection, etc. of a cold plate type liquid cooling server in the prior art.

[0034] Figure 1 The structure of a testing device for a server according to an embodiment of the present disclosure is schematically shown.

[0035] like Figure 1 As shown, the test device includes a controller 19 and a pipeline 22.

[0036] The pipeline 22 is provided with a switching valve 3 , a pressure sensor 15 and a detection unit. The switching valve 3 is provided at a first end of the pipeline 22 so that the server 21 is connected to a plurality of gas sources through the pipeline 22 .

[0037] The controller 19 is used to receive a first operation instruction indicating a first functional test and a second operation instruction for a second functional test, wherein the first operation instruction is used to instruct the switching valve 3 to switch the test gas in the pipeline 22 to the first gas and close the detection unit, and control the use of the pressure sensor 15 to perform a first functional test on the server 21; the second operation instruction is used to instruct the switching valve 3 to switch the test gas in the pipeline 22 to the second gas, and control the use of the pressure sensor 15 and the detection unit to perform a second functional test on the server 21.

[0038] According to an embodiment of the present disclosure, the gas source may be an air source or an inert gas source. For example, the air source may be a compressed air source, which may be used to check for leaks in the joints, pipelines, cold plates, etc. of the server. The inert gas source may be a nitrogen source, which may be used to provide gas protection for the server to prevent the components in the server from being corroded, causing problems such as short circuits.

[0039] For example, the first functional test may be a test related to an air gas source, and the second functional test may be a test related to an inert gas source.

[0040] Figure 2 A schematic diagram of a cold plate liquid cooling radiator according to an embodiment of the present disclosure is schematically shown.

[0041] like Figure 2 As shown, the server 21 has a cold plate type liquid cooling radiator. The cold plate type liquid cooling radiator includes a cold plate cavity 211. The cold plate cavity 211 can be cooled by deionized water, formula liquid and other cooling substances, and the cooling substances can reach the heat-generating device accessories through the pipeline in the server. The heat of the device 213 can be transferred to the cold plate cavity 211 by using thermal conductive silicone grease 212 to achieve the effect of heat dissipation.

[0042] Before filling the cold plate liquid cooling radiator, it is necessary to conduct air tightness test on the joints, pipes, cold plate, etc. After the test is completed, inert gas needs to be filled into the server to reduce pipe corrosion, reduce bacterial growth, and extend the service life of the cold plate and the entire pipe.

[0043] According to an embodiment of the present disclosure, the switching valve 3 may be an electric three-way valve. The electric three-way valve realizes online free switching without the need for gas source disconnection operation, and the airtight pressure maintenance can use not only air but also inert gas directly.

[0044] According to an embodiment of the present disclosure, a testing device for a server includes a controller and a pipeline. A switching valve, a pressure sensor and a detection unit are provided on the pipeline, and the switching valve can connect the server to multiple gas sources through the pipeline. When the controller receives a first operation instruction indicating a first functional test, the switching valve can be controlled to switch the test gas in the pipeline to the first gas and close the detection unit, and control the pressure sensor to perform a first functional test on the server. When the controller receives a first operation instruction indicating a second functional test, the switching valve can be controlled to switch the test gas in the pipeline to the second gas, and control the pressure sensor and the detection unit to perform a second functional test on the server. The testing device can switch and connect multiple gas sources to perform multiple functional tests on the server using the same pipeline, realizing multi-purpose integration, simplifying the testing process, and improving equipment utilization.

[0045] According to an embodiment of the present disclosure, the detection unit can be used to measure the concentration of the first gas or the second gas in the pipeline 22. For example, the detection unit can be set at any position in the pipeline 22. The detection unit is set close to the gas source and can detect the purity of the inert gas source to ensure that the device 213 in the server 21 is not corroded.

[0046] According to an embodiment of the present disclosure, there may be multiple pressure sensors 15, which are respectively arranged at different positions of the pipeline 22. For example, according to the change of the pressure value sensed by the sensor 15, it is determined whether the joints, pipelines, and cold plates of the server have leaks.

[0047] According to an embodiment of the present disclosure, the detection unit includes a first detection subunit and a second detection subunit. The first end of the switching valve 3 is respectively connected to multiple gas sources. The first detection unit is arranged near the second end of the switching valve 3 to detect the gas concentration at the first end of the pipeline 22. The second detection unit is arranged at the second end of the pipeline 22 to detect the gas concentration at the second end.

[0048] According to an embodiment of the present disclosure, the first gas source interface 1 can be used to connect to an air source, and the second gas source interface 2 can be used to connect to an inert gas source.

[0049] For example, the first end of the switching valve 3 is switched to be connected to the first air source interface 1 to deliver the air source to the pipeline 22 .

[0050] For example, the first end of the switching valve 3 is switched to be connected to the second gas source interface 2 to deliver the inert gas source to the pipeline 22 .

[0051] The first gas source interface 1 and the second gas source interface 2 may both be C-type self-locking joints.

[0052] According to an embodiment of the present disclosure, the pipeline 22 is further provided with an air inlet 13 and an air outlet 14 , a first end of the air inlet 13 is connected to an air input port of the server 21 , and a first end of the air outlet 14 is connected to an air output port of the server 21 .

[0053] According to an embodiment of the present disclosure, a pressure stabilizing tank 10 and an electrical proportional valve 11 are provided on the pipeline 22 between the first detection subunit and the pressure sensor 15 . The pressure stabilizing tank 10 is used to adjust the gas flow in the pipeline 22 , and the electrical proportional valve 11 is used to adjust the gas pressure in the pipeline 22 .

[0054] According to an embodiment of the present disclosure, a manual sliding valve 4 is further provided on the pipeline 22 , and the second end of the switching valve 3 is connected to the manual sliding valve 4 , and the manual sliding valve 4 is used to reduce the air pressure in the pipeline 22 .

[0055] According to the embodiment of the present disclosure, the manual sliding valve 4 can realize the on-off and pressure relief functions of the source, so as to facilitate component replacement and maintenance.

[0056] According to an embodiment of the present disclosure, a filter assembly 5 and a gas management unit 6 are provided on the pipeline 22 between the switching valve 3 and the first detection subunit, the filter assembly 5 is used to filter debris in the pipeline 22, and the gas management unit 6 is used to monitor the gas in the pipeline.

[0057] The filter assembly 5 can achieve 1 micron coarse filtration and 0.1 micron fine filtration, and the impurities filtered include dust, water and oil mist. This ensures that the gas entering the server pipeline and cold plate is clean and free of impurities, avoiding pollution to the connected liquid cooling system. At the same time, the pressure regulating valve of the filter assembly 5 can also be used to adjust the pressure of the main pipeline to prevent excessive pressure from damaging some components.

[0058] The gas management unit 6 is used to monitor the gas pressure and flow to avoid bad test results caused by insufficient gas source.

[0059] During the first function test and the second function test, the filter assembly 5, the gas management unit 6, the electrical proportional valve 11, the muffler 12, the pressure sensor, and the data acquisition board 20 are all in the open state.

[0060] The data acquisition board 20 is used to store the data collected by various sensors and transmit the data collected by each sensor to the controller 19 .

[0061] According to an embodiment of the present disclosure, the first functional test includes an airtightness test, the second end of the exhaust port 14 is connected to the electric ball valve 16, and the device further includes a solenoid valve 7, which is electrically connected to the first detection subunit.

[0062] The controller 19 is further configured to: in response to receiving a first operation instruction indicating an airtightness test, control the switching valve 3 to switch the test gas in the pipeline 22 to the first gas, control the solenoid valve 7 to close the first detection subunit, and control the electric ball valve 16, the air inlet 13, and the exhaust port 14 to open, so as to deliver the first gas to the server 21. When the first pressure value sensed by the pressure sensor 15 meets the airtight pressure condition, the electric ball valve 16 is closed to perform an airtightness test on the server 21.

[0063] Before injecting liquid into the server, perform an air tightness test, complete the gas injection at the specified pressure, and after maintaining the pressure for a period of time, repeat the pressure changes in the internal pipelines of the cold plate liquid cooling server to identify the leakage point.

[0064] For example, after the electric ball valve 16, the air inlet 13 and the air outlet 14 are opened, the gas management unit 6 can be used to monitor the pressure of the input gas source. When the gas source pressure value sensed by the gas management unit 6 meets the gas source airtight condition, the electric ball valve 16 is closed. The gas source airtight condition can be conditions such as gas source pressure and gas flow.

[0065] Control the electrical proportional valve 11 to adjust the air pressure in the pipeline 22 to a preset pressure. Continue to input the first gas into the server 21 until the first pressure value sensed by the pressure sensor 15 meets the second airtight pressure condition. The second airtight pressure condition can be that the first pressure value is greater than or equal to the airtight pressure value. Then close the gas source inlet to see if the pressure value changes within the preset airtight time. If it decreases, the airtightness test fails. If it does not change, the airtightness test passes.

[0066] According to an embodiment of the present disclosure, the pressure sensor 15 is connected to the second end of the air inlet 13 , and the first detection subunit includes a first pressure reducing valve 8 and a first gas concentration sensor 9 .

[0067] A pressure stabilizing tank 10 is provided in the pipeline 22 to eliminate interference caused by air flow fluctuations. In addition, in order to achieve precise control of the input pressure, a closed-loop control is formed through a pressure sensor 15 and an electric proportional valve 11.

[0068] According to an embodiment of the present disclosure, the second functional test also includes a nitrogen filling test, and the other end of the electric ball valve 16 is connected to the second detection subunit.

[0069] For example, the second detection subunit includes a second pressure reducing valve 17 and a second gas concentration sensor 18 .

[0070] According to an embodiment of the present disclosure, the controller is also used for: in response to receiving a second operation instruction indicating a nitrogen filling test, controlling the switching valve 3 to switch the test gas in the pipeline 22 to a second gas, and respectively opening the solenoid valve 7, the electric ball valve 16, the air inlet 13 and the exhaust port 14 to respectively open the first detection subunit and the second detection subunit; when the gas concentration at the first end of the pipeline 22 detected by the first gas concentration sensor 9 meets the starting gas concentration condition, closing the solenoid valve 7; when the gas concentration at the second end of the pipeline 22 detected by the second detection subunit meets the end gas concentration condition, closing the electric ball valve 16 to deliver the second gas to the server 21 until the second pressure value sensed by the pressure sensor 15 meets the nitrogen filling pressure condition.

[0071] After the air tightness test of the server is completed, inert nitrogen gas at a specified pressure is injected into the pipeline.

[0072] According to an embodiment of the present disclosure, the starting-end gas concentration condition may be that the gas concentration at the first end of the pipeline is greater than or equal to a starting-end gas concentration threshold.

[0073] According to an embodiment of the present disclosure, the terminal gas concentration condition may be that the gas concentration at the second end of the pipe segment is greater than or equal to a terminal gas concentration threshold.

[0074] For example, during the nitrogen filling test, the control switching valve 3 is switched to the second gas source interface to deliver nitrogen to the pipeline 22. In order to ensure the purity of the nitrogen source, the first gas concentration sensor 9 is used for measurement. After nitrogen is introduced into the server pipeline and the cold plate for a period of time, the second gas concentration sensor 18 measures the nitrogen concentration at the output port of the server 21 to ensure that the air in the internal pipeline of the server 21 has been completely replaced by nitrogen, thereby ensuring that the internal pipeline and cold plate of the server 21 are almost anaerobic, inhibiting the growth of aerobic bacteria, and preventing bacteria from contaminating the connected liquid cooling system. Then, nitrogen under nitrogen filling pressure conditions is input into the pipeline 22.

[0075] According to an embodiment of the present disclosure, the device further includes a solenoid valve 7, which is electrically connected to the first detection subunit, and the second functional test includes a gas quality inspection test.

[0076] The controller is also used for: in response to receiving a second operation instruction indicating a gas quality inspection test, controlling the exhaust port 14 to close, controlling the solenoid valve 7 to open the first detection subunit, and using the first detection subunit to detect the gas concentration at the first end of the pipeline 22 to obtain a first detection result; when the first detection result indicates that the gas concentration at the first end of the pipeline 22 meets a preset gas concentration condition, closing the first detection subunit; when the pressure value sensed by the pressure sensor 15 meets the quality inspection pressure condition, opening the air inlet 13 to connect the pipeline 22 to the server 21; determining the test result of the gas quality inspection test according to the pressure change value sensed by the pressure sensor 15, the pressure change value indicating the concentration change of the second gas in the server.

[0077] According to an embodiment of the present disclosure, the gas quality inspection test is used to randomly check whether the server 21 reaches a specified pressure during the air tightness and nitrogen filling process.

[0078] According to an embodiment of the present disclosure, the preset gas concentration condition may be greater than or equal to a concentration threshold.

[0079] According to an embodiment of the present disclosure, the quality inspection pressure condition may be greater than or equal to a quality inspection pressure threshold.

[0080] According to an embodiment of the present disclosure, during the gas quality inspection test, the second gas is first input into the pipeline 22 until the gas concentration at the first end of the pipeline 22 meets the preset gas concentration condition; when the pressure value sensed by the pressure sensor 15 meets the quality inspection pressure condition, the air inlet 13 is opened to determine that the gas pressure and gas concentration in the pipeline are consistent with the nitrogen filling standard of the server. Then the server 21 is connected to the pipeline 22. It should be noted that the server 21 may have been tested for nitrogen filling, that is, there is a certain amount of nitrogen in the server 21. In order to verify whether the nitrogen filling amount in the nitrogen filling test is qualified, a gas quality inspection test is performed. When the pressure value sensed by the pressure sensor 15 remains unchanged, the test result of the gas quality inspection test is determined to be qualified. When the pressure value sensed by the pressure sensor 15 changes, the test result of the gas quality inspection test is determined to be qualified.

[0081] According to an embodiment of the present disclosure, for the same type of test, a batch test server can be performed, and multiple test branches can be set in the pipeline 22. For example, the pipeline 22 includes a first test branch 101 and a second test branch 102, and the first test branch 101 and the second test branch have the same sensor settings.

[0082] According to an embodiment of the present disclosure, a testing method for a server is applied to a testing device for a server, the method comprising: in response to receiving a first operating instruction indicating a first functional test, controlling a switching valve to switch the test gas in a pipeline to a first gas and closing a detection unit so as to perform a first functional test on the server using a pressure sensor; in response to receiving a second operating instruction indicating a second functional test, controlling the switching valve to switch the test gas in the pipeline to a second gas, and performing a second functional test on the server using both the pressure sensor and the detection unit.

[0087] In operation S303, it is determined whether the gas source pressure value sensed by the gas management unit meets the gas source airtight condition. If yes, operation S305 is performed; if not, operation S304 is performed.

[0088] In operation S304, the test is suspended until the gas source pressure in the pipeline meets the gas source airtight condition.

[0089] In operation S305, the electric ball valve is closed.

[0090] In operation S306 , the electric proportional valve is controlled to adjust the gas pressure in the pipeline to a preset pressure.

[0091] In operation S307, it is determined whether the first pressure value sensed by the pressure sensor satisfies the second airtight pressure condition. If so, operation S308 is performed, and if not, operation S306 is performed.

[0092] In operation S308, the gas source inlet is closed.

[0093] In operation S309, it is determined whether the pressure drop within the preset airtight time is within a preset range. If so, operation S310 is performed; if not, operation S311 is performed.

[0112] like Figure 5 As shown, the nitrogen filling test of this embodiment includes operations S501-S510.

[0113] In operation S501 , in response to receiving a second operation instruction instructing a nitrogen filling test, the switching valve is controlled to switch the test gas in the pipeline to a second gas.

[0114] In operation S502, the solenoid valve, the electric ball valve, the air inlet, and the air outlet are opened respectively to start the first detection subunit and the second detection subunit respectively.

[0115] In operation S503, it is determined whether the gas source pressure value sensed by the gas management unit meets the gas source nitrogen filling condition. If yes, operation S505 is executed; if not, operation S504 is executed.

[0116] In operation S504, the test is suspended until the gas source pressure in the pipeline meets the gas source nitrogen filling condition.

[0122] In operation S510, the switching valve is controlled to be opened to continue injecting the second gas.

[0123] For the three tests of air tightness pressure maintenance, constant pressure nitrogen filling and gas quality inspection test (pressure readback) of the server, the test device used for the server performs leak detection on the cold plate liquid cooling server before the liquid filling test to prevent damage to electronic components caused by leakage. After the test is completed, constant pressure liquid filling is performed to maintain an oxygen-free environment inside, inhibit the growth of aerobic bacteria, and prevent bacteria from contaminating the connected liquid cooling system. In addition, it can also be used in the quality inspection process to detect whether the nitrogen filling pressure meets the requirements. It realizes multiple uses of one machine and reduces equipment costs and usage space.

[0124] Effective control measures such as gas source purification, gas source parameter monitoring, and gas source pressure stabilization are implemented to avoid contamination of the pipelines and cold plates of the cold plate liquid cooling server and instability of pressure control. In addition, nitrogen concentration is tested to ensure that the nitrogen concentration meets the requirements.
