Description

Technical Field

[0001] This application relates to the field of liquid cooling technology, and for example to a testing device for liquid cooling equipment. Background Technology

[0002] In modern data centers, with the continuous increase in computing density, traditional air cooling methods are no longer sufficient to meet the demand for efficient heat dissipation. Liquid cooling technology has gradually become the mainstream solution. Liquid cooling equipment can achieve efficient heat transfer and heat dissipation, significantly improving the working stability and energy efficiency of electronic devices (such as servers, computing boards, etc.).

[0003] Currently, liquid cooling equipment requires a series of testing steps during factory testing and operation and maintenance.

[0031] This application provides a testing device for liquid cooling equipment (hereinafter referred to as the testing device), such as Figures 1 to 3 As shown, the testing device includes a gas supply assembly 100, a liquid supply assembly 700, a liquid collection tank 800, a first valve group 200, a second valve group 500, a first pipeline 300, and a second pipeline 600. The gas outlet of the gas supply assembly 100 and the liquid outlet of the liquid supply assembly 700 are respectively connected to multiple inlet ends of the first valve group 200. The two ends of the first pipeline 300 are respectively connected to the outlet end of the first valve group 200 and the inlet end of the liquid cooling device 400. The gas return end of the gas supply assembly 100, the liquid inlet end of the liquid supply assembly 700, and the liquid inlet end of the liquid collection tank 800 are respectively connected to multiple outlet ends of the second valve group 500. The two ends of the second pipeline 600 are respectively connected to the outlet end of the liquid cooling device 400 and the inlet end of the second valve group 500.

[0032] In this configuration, one of the multiple inlet ends of the first valve group 200 can be selectively connected to the outlet end of the first valve group 200. One of the multiple outlet ends of the second valve group 500 can be selectively connected to the inlet end of the second valve group 500, or all of the multiple outlet ends of the second valve group 500 can be disconnected from the inlet end of the second valve group 500.

[0033] In this embodiment, the first valve group 200 has multiple inlet ends. The outlet end of the gas supply component 100 can be connected to one inlet end of the first valve group 200 (hereinafter referred to as the gas supply inlet end), and the outlet end of the liquid supply component 700 can be connected to another inlet end of the first valve group 200 (hereinafter referred to as the liquid supply inlet end). The two ends of the first pipeline 300 are respectively connected to the outlet end of the first valve group 200 and the inlet end of the liquid cooling device 400. The multiple inlet ends of the first valve group 200 can be selectively connected to the outlet end of the first valve group 200. In one case, the gas supply inlet end is connected to the outlet end of the first valve group 200, and the outlet end of the gas supply component 100 can be connected to the liquid cooling device 400 through both the first valve group 200 and the first pipeline 300 to supply gas to the liquid cooling device 400. In another scenario, the liquid supply inlet is connected to the outlet of the first valve group 200, and the liquid supply component 700 can be connected to the liquid cooling equipment 400 through both the first valve group 200 and the first pipeline 300 to supply liquid to the liquid cooling equipment 400.

[0034] The second valve group 500 has multiple outlets. The return gas end of the gas supply component 100 can be connected to the outlet end of one second valve group 500 (hereinafter referred to as the return gas outlet end). The liquid inlet end of the liquid supply component 700 can be connected to the outlet end of another second valve group 500 (hereinafter referred to as the liquid return outlet end). The liquid inlet end of the liquid collection tank 800 can be connected to the outlet end of yet another second valve group 500 (hereinafter referred to as the liquid collection outlet end). The two ends of the second pipeline 600 are respectively connected to the outlet end of the liquid cooling equipment 400 and the inlet end of the second valve group 500.

[0035] In one scenario, the inlet of the second valve assembly 500 is connected to the return gas outlet, allowing the liquid cooling device 400 to connect to the return gas outlet of the gas supply assembly 100 via both the second pipe 600 and the second valve assembly 500, thus enabling the gas inside the liquid cooling device 400 to be discharged. In another scenario, the inlet of the second valve assembly 500 is connected to the return liquid outlet, allowing the liquid cooling device 400 to connect to the liquid inlet of the liquid supply assembly 700 via both the second pipe 600 and the second valve assembly 500, thus enabling the liquid inside the liquid cooling device 400 to flow into the liquid supply assembly 700. In yet another scenario, the inlet of the second valve assembly 500 is connected to the collection outlet, allowing the liquid cooling device 400 to connect to the liquid inlet of the collection tank 800 via both the second pipe 600 and the second valve assembly 500, thus enabling the liquid inside the liquid cooling device 400 to be discharged into the collection tank 800. In another scenario, multiple outlets of the second valve group 500 are disconnected from the inlet of the second valve group 500. That is, the return gas end of the gas supply component 100, the liquid inlet end of the liquid supply component 700, and the liquid inlet end of the liquid collection tank 800 are not connected to the outlet end of the liquid cooling device 400. The outlet end of the liquid cooling device 400 can be blocked so that liquid or gas can remain inside the liquid cooling device 400.

[0036] By setting up the first valve group 200, gas or liquid can be supplied to the liquid cooling equipment 400, increasing the variety of fluid media that can be added to the liquid cooling equipment 400. By setting up the second valve group 500, the media discharged from the liquid equipment (such as gaseous or liquid media) can have multiple different flow paths, enabling different test operations on the liquid cooling equipment 400 and increasing the test procedures that the testing device can perform. In this way, the testing device can perform a variety of tests on the liquid cooling equipment 400, reducing the number of testing tools used and the switching steps between different testing tools, improving testing efficiency and reducing testing costs.

[0037] For example, when the outlet end of the gas supply assembly 100 is connected to the outlet end of the first valve group 200, the return end of the gas supply assembly 100 is connected to the inlet end of the second valve group 500, or the inlet end of the liquid collection tank 800 is connected to the inlet end of the second valve group 500, or the outlet end of the second valve group 500 is blocked.

[0038] When the outlet of the gas supply assembly 100 is connected to the outlet of the first valve group 200 (i.e., the gas supply inlet is connected to the outlet of the first valve group 200), the gas supply assembly 100 can supply gas to the liquid cooling device 400 through the first valve group 200 and the first pipeline 300. When the inlet of the liquid collection tank 800 (equivalent to the liquid collection outlet) is connected to the inlet of the second valve group 500, the gas supply assembly 100 can supply pressurized gas to the liquid cooling device 400, discharging the liquid in the liquid cooling device 400 into the liquid collection tank 800, thus realizing the liquid drainage operation of the liquid cooling device 400.

[0039] Alternatively, when the return gas end (equivalent to the return gas outlet end) of the gas supply assembly 100 is connected to the inlet end of the second valve group 500, gas can be supplied to the liquid cooling equipment 400 through the gas supply assembly 100, and the gas can flow back into the gas supply assembly 100 through the second pipeline 600 and the second valve group 500, so as to perform a blowing cleaning operation inside the liquid cooling equipment 400.

[0040] Alternatively, the outlet end of the second valve group 500 can be blocked, that is, multiple outlet ends of the second valve group 500 are disconnected from the inlet end of the second valve group 500, and the fluid medium cannot flow out of the second valve group 500. In this way, when the gas supply component 100 supplies gas to the liquid cooling equipment 400, the gas can be retained in the liquid cooling equipment 400 to perform pressure holding tests on the liquid cooling equipment 400.

[0041] In this application, by switching the components connected to the liquid cooling equipment 400 through the second valve group 500, or by blocking the outlet end of the second valve group 500, different operations such as air supply, liquid discharge, air exhaust, and pressure holding can be performed on the liquid cooling equipment 400, reducing the use of testing tools, lowering testing costs, and improving testing efficiency.

[0042] Furthermore, when the liquid supply component 700 is connected to the outlet end of the first valve group 200, the liquid supply component 700 is connected to the inlet end of the second valve group 500, or the liquid collection tank 800 is connected to the inlet end of the second valve group 500.

[0043] When the outlet end of the liquid supply assembly 700 is connected to the outlet end of the first valve group 200 (i.e., the inlet end of the liquid supply assembly is connected to the outlet end of the first valve group 200), the liquid in the liquid supply assembly 700 can flow into the liquid cooling device 400. When the inlet end of the liquid supply assembly 700 (equivalent to the return outlet end) is connected to the inlet end of the second valve group 500, the liquid in the liquid cooling device 400 can flow back into the liquid supply assembly 700 through both the second pipeline 600 and the second valve group 500. The liquid can circulate within the liquid supply assembly 700, the first valve group 200, the first pipeline 300, the liquid cooling device 400, the second pipeline 600, and the second valve group 500. For example, the liquid cooling device 400 can be filled or tested for thermal resistance and flow resistance.

[0044] Alternatively, the inlet end of the liquid collection tank 800 (equivalent to the liquid collection outlet end) is connected to the inlet end of the second valve group 500. In this way, the liquid flowing into the liquid cooling device 400 from the liquid supply component 700 can flow out of the liquid cooling device 400 and flow into the liquid collection tank 800. For example, the liquid in the liquid supply component 700 can be used to perform a draining and flushing operation inside the liquid cooling device 400.

[0045] In this application, the second valve group 500 switches the components connected to the liquid cooling equipment 400, enabling different operations such as filling, draining and testing of the liquid cooling equipment 400, reducing the use of testing tools, lowering testing costs and improving testing efficiency.

[0046] The outlet end of the first pipeline 300 may be provided with a first quick connector, and the first pipeline 300 can be connected to the inlet end of the liquid cooling equipment 400 through the first quick connector to improve the connection efficiency between the first pipeline 300 and the liquid cooling equipment 400.

[0047] The inlet end of the second pipeline 600 may be provided with a second quick connector, and the second pipeline 600 can be connected to the outlet end of the liquid cooling equipment 400 through the second quick connector to improve the connection efficiency between the second pipeline 600 and the liquid cooling equipment 400.

[0048] For example, such as Figure 1 and Figure 2 As shown, the first valve group 200 may include, for example, a first multi-way valve 210. The first multi-way valve 210 is provided with a first outlet end and a plurality of first inlet ends, and the plurality of first inlet ends can be selectively connected to the first outlet end.

[0049] The first multi-way valve 210 is provided with multiple first inlet ends, and the gas outlet end of the gas supply component 100 and the liquid outlet end of the liquid supply component 700 can be connected to the corresponding first inlet ends respectively. In this way, by controlling the first inlet end connected to the first outlet end, the gas supply component 100 can be connected to the liquid cooling device 400, or the liquid supply component 700 can be connected to the liquid cooling device 400, so as to supply gas or liquid to the liquid cooling device 400.

[0050] Or, such as Figure 3 As shown, the first valve group 200 includes, for example, a first outlet pipe 220, a plurality of first inlet pipes 230 and a plurality of first two-way valves 240. The plurality of first inlet pipes 230 are all connected to the first outlet pipe 220, and the number of first two-way valves 240 is the same as the number of first inlet pipes 230 and corresponds one-to-one.

[0051] The first valve assembly 200 includes multiple first liquid inlet pipes 230. The gas outlet of the gas supply assembly 100 and the liquid outlet of the liquid supply assembly 700 can be connected to the corresponding first liquid inlet pipes 230, respectively. The number of first two-way valves 240 is the same as the number of first liquid inlet pipes 230, and the multiple first two-way valves 240 are respectively located on the corresponding first liquid inlet pipes 230. In this way, by controlling the opening and closing of the multiple first two-way valves 240, the first liquid inlet pipes 230 connected to the first liquid outlet pipe 220 can be controlled, thereby controlling the connection between the gas supply assembly 100 and the liquid cooling equipment 400, or the connection between the liquid supply assembly 700 and the liquid cooling equipment 400, to supply gas or liquid to the liquid cooling equipment 400.

[0052] It should be noted that the specific implementation of the first valve group 200 described above is merely exemplary. As long as the communication function of the first valve group 200 can be achieved, the specific implementation of the first valve group 200 can be set according to the specific specifications of the testing device or the specific testing requirements of the testing device. For example, the first valve group 200 can also be a combination of a multi-way valve and a two-way valve, or a combination of two multi-way valves; no specific limitation is made here. The term "first multi-way valve 210" refers to a valve with three or more valve ports.

[0053] For example, such as Figure 1 and Figure 2 As shown, the second valve group 500 may include, for example, a second multi-way valve 510. The second multi-way valve 510 is provided with a second inlet end and multiple second outlet ends. The multiple second outlet ends can be selectively connected to the second inlet end, or all of the multiple second outlet ends can be disconnected from the second inlet end.

[0054] The second multi-way valve 510 has multiple second outlets. The return gas end of the gas supply component 100, the liquid inlet end of the liquid supply component 700, and the liquid inlet end of the liquid collection tank 800 are respectively connected to the corresponding second outlet. Each of the multiple second outlets can be selectively connected to the second inlet end, or all of them can be disconnected from the second inlet end. This allows control of the second outlets connected to the second inlet end to control the gas supply component 100, the liquid supply component 700, or the liquid collection tank 800 connected to the liquid cooling equipment 400, thereby changing the flow path of the fluid medium; or it can control the second inlet end to disconnect from the second outlet end, allowing the fluid medium to be stored within the liquid cooling equipment 400.

[0055] For example, the first multi-way valve 210 or the second multi-way valve 510 can be a single-position multi-way valve, which is a valve that has multiple inlets and a common outlet (or vice versa), and changes the direction of fluid flow or distributes fluid to different outlets by rotating or sliding the valve core.

[0056] For example, such as Figure 3 As shown, the second valve group 500 may include, for example, a second inlet pipe 520, a plurality of second outlet pipes 530 and a plurality of second two-way valves 540. The plurality of second outlet pipes 530 are all connected to the second inlet pipe 520, and the number of second two-way valves 540 is the same as the number of second outlet pipes 530 and corresponds one-to-one.

[0057] The second valve assembly 500 includes multiple second outlet pipes 530. The return gas end of the gas supply assembly 100, the inlet end of the liquid supply assembly 700, and the inlet end of the liquid collection tank 800 are respectively connected to the corresponding second outlet pipes. The number of second two-way valves 540 is the same as the number of second outlet pipes 530, and multiple second two-way valves 540 are respectively located on the corresponding second outlet pipes 530. In this way, by controlling the opening and closing of multiple second two-way valves 540, the second outlet pipes 530 connected to the second inlet pipe 520 can be controlled, thereby controlling the connection between the liquid cooling device 400 and the gas supply assembly 100, or the liquid cooling device 400 and the liquid supply assembly 700, or the liquid cooling device 400 and the liquid collection tank 800, changing the flow path of the fluid medium flowing out of the liquid cooling device 400, or controlling multiple second outlet pipes 530 to not be connected to the second inlet pipe 520, thereby sealing the outlet end of the liquid cooling device 400.

[0058] It should be noted that the specific implementation of the second valve group 500 described above is merely exemplary. As long as the connection function of the second valve group 500 can be achieved, the specific implementation of the second valve group 500 can be set according to the specific specifications of the testing device or the specific testing requirements of the testing device. For example, the second valve group 500 can also be a combination of a multi-way valve and a two-way valve, or a combination of two multi-way valves; no specific limitation is made here. The term "second multi-way valve 510" refers to a valve with three or more valve ports.

[0059] For example, such as Figure 2 and Figure 3 As shown, the air supply assembly 100 includes an air tank 110 and an air compressor 120. The inlet end of the air tank 110 is connected to the outlet end of a second valve group 500. The outlet end of the air compressor 120 is connected to the inlet end of a first valve group 200, and the inlet end of the air compressor 120 is connected to the outside and / or the air tank 110.

[0060] The air compressor 120 is connected to the air supply inlet, which can supply air to the liquid cooling equipment 400 and increase the air pressure inside the liquid cooling equipment 400. This enables the liquid cooling equipment 400 to be drained, blown, or pressure-held for pressure testing, thus improving the operational versatility of the testing device.

[0061] The inlet of the gas storage tank 110 is connected to the return gas outlet, allowing gas flowing out of the liquid cooling equipment 400 to flow into the gas storage tank 110 for gas recovery, reducing gas leakage and improving the operational stability and safety of the testing device. For example, during the operation and maintenance of the liquid cooling equipment 400, when it is purged with air, the gas contains liquid media. If this gas is discharged to the outside, it will increase air humidity, and the liquid media may even volatilize toxic gases, causing harm to electronic equipment and operators.

[0062] When the air inlet of the air compressor 120 is connected to the outside, the air compressor 120 can drive outside air into the liquid cooling device 400 to supply air to the liquid cooling device 400.

[0063] The gas storage tank 110 can store gaseous medium. When the air compressor 120 is connected to the gas storage tank 110, the air compressor 120 can drive the gas in the gas storage tank 110 to the liquid cooling device 400. At the inlet and outlet of the gas storage tank 110, the gas can circulate within the gas storage tank 110, the air compressor 120, the first valve group 200, the first pipeline 300, the liquid cooling device 400, the second pipeline 600, and the second valve group 500, thereby improving the gas utilization rate.

[0064] For example, such as Figure 2 and Figure 3 As shown, the testing device may also include a first pressure sensor 910, which is located in the first connecting pipeline between the air outlet of the air compressor 120 and the first valve group 200, or in the first pipeline 300, or in the second pipeline 600.

[0065] For example, during a pressure holding test on the liquid cooling device 400, air is supplied to the liquid cooling device 400 via an air compressor 120, and the second valve assembly 500 is sealed, allowing the gas to be stored within the liquid cooling device 400. Once the gas pressure within the liquid cooling device 400 meets the set pressure and stabilizes, the air compressor 120 can be shut off to seal the gas within the first connecting pipe, the first pipe 300, the liquid cooling device 400, and the second pipe 600. At this time, the pressure within the first connecting pipe, the first pipe 300, the second pipe 600, and the liquid cooling device 400 is the same. A first pressure sensor 910 is installed in the first connecting pipe, the first pipe 300, or the second pipe 600 to detect the pressure within these pipes, indirectly detecting the pressure within the liquid cooling device 400 and improving the testing effectiveness of the testing device.

[0066] Furthermore, multiple pressure values ​​within the liquid cooling device 400 can be continuously or at set intervals using the first pressure sensor 910, so as to determine the pressure holding effect of the liquid cooling device 400 based on the multiple pressure values. It is understood that the above description of the pressure holding test is merely illustrative and intended only to facilitate understanding of this solution by those skilled in the art, and does not constitute the scope of protection of this application.

[0067] The testing device may also include a second pressure sensor 920, which is located in the second connecting pipe between the inlet end of the gas storage tank 110 and the second valve group 500. When gas flows through the second valve group 500 into the gas storage tank 110, the second pressure sensor 920 can detect the pressure in the second connecting pipe. By acquiring the gas pressure at different locations within the testing device, multi-location monitoring of the testing device can be performed, improving the testing effect.

[0068] For example, such as Figure 2 and Figure 3 As shown, the liquid supply assembly 700 may include a liquid supply pipe 710 and a drive pump 720. The outlet end of the liquid supply pipe 710 is connected to the inlet end of another first valve group 200, and the inlet end of the liquid supply pipe 710 is connected to the outlet end of another second valve group. The drive pump 720 is located in the liquid supply pipe 710.

[0069] The outlet end of the liquid supply pipe 710 is connected to the liquid supply inlet end, and the inlet pipe of the liquid supply pipe 710 is connected to the return outlet end. The drive pump 720 is installed in the liquid supply pipe 710. When the liquid supply inlet end is connected to the outlet end of the first valve group 200, and the inlet end of the second valve group 500 is connected to the return outlet end, the liquid medium can circulate within the liquid supply pipe 710, the first valve group 200, the first pipeline 300, the liquid cooling equipment 400, the second pipeline 600, and the second valve group 500 under the drive of the pump 720.

[0070] The liquid supply pipe 710 may be equipped with a liquid supply port that can be connected to an external liquid supply tank. Thus, when the testing device begins supplying liquid to the liquid cooling equipment 400, the liquid supply port can be connected to the external liquid supply tank to increase the liquid inflow into the testing device and the liquid cooling equipment 400. Once the liquid volume in the testing device and the liquid cooling equipment 400 reaches a set volume and the liquid can flow stably within them, the liquid supply port can be disconnected from the external liquid supply tank, and the pump 720 can be driven to circulate the liquid within the testing device and the liquid cooling equipment 400. This reduces the amount of liquid used in the testing device and lowers testing costs.

[0071] Alternatively, the liquid supply assembly 700 may also include a liquid storage tank, with the liquid supply pipe 710 connected to the liquid storage tank. A drive pump 720 is located in the liquid supply pipe 710, and the drive pump 720 can drive the liquid in the liquid storage tank to the liquid cooling device 400, and drive the liquid to circulate within the testing device and the liquid cooling device 400. By providing a liquid storage tank, the total amount of liquid in the testing device and the liquid cooling device 400 can be greater than or equal to the total amount of liquid required for the test, thereby reducing the occurrence of unstable or insufficient liquid volume and improving the operational stability and reliability of the testing device.

[0072] like Figure 2 As shown, the testing device may also include a one-way valve 930, which is located in the liquid supply pipe 710. The one-way valve 930 allows the liquid to flow unidirectionally between the inlet and outlet ends of the liquid supply pipe 710, reducing the occurrence of liquid flowing from the outlet end to the inlet end of the liquid supply pipe 710 due to unstable liquid flow or turbulence, thereby improving the operational stability and reliability of the testing device.

[0073] For example, such as Figure 2 and Figure 3 As shown, the testing device may also include a temperature sensor 940, which is located in the liquid supply pipe 710 or the second pipe 600 to detect the temperature of the liquid discharged from the liquid cooling device 400.

[0074] For example, the testing apparatus may also include a flow sensor 950, and the flow sensor 950 may be provided at the outlet end and / or the inlet end of the supply pipe 710.

[0075] The liquid supply pipe 710 may be equipped with a flow sensor 950 at its outlet end to detect the flow rate of the liquid supplied to the liquid cooling device 400. The liquid supply pipe 710 may be equipped with a flow sensor 950 at its inlet end to detect the flow rate of the liquid flowing out of the liquid cooling device 400.

[0076] For example, such as Figures 1 to 3As shown, there can be one or more liquid supply components 700. When there are multiple liquid supply components 700, at least two of them contain different types of liquid media. By setting up multiple liquid supply components 700, different types of liquid media can be supplied to the liquid cooling device 400 for different tests. This reduces the number of testing tools used and the steps required to switch liquid media, improving testing efficiency and reducing testing costs.

[0077] For example, the multiple liquid supply components 700 include a first liquid supply component and a second liquid supply component. The first liquid supply component is used to supply coolant (e.g., fluorinated liquid) to the liquid cooling device 400 so that thermal resistance and flow resistance tests can be performed on the liquid cooling device 400. The second liquid supply component is used to supply deionized water to the liquid cooling device 400 so that the interior of the liquid cooling device 400 can be cleaned.

[0078] It is understood that the above description of the liquid medium in the multiple liquid supply components 700 is merely exemplary. The number of liquid supply components 700 and the types of liquid medium that can flow through the multiple liquid supply components 700 can be set according to the testing requirements of the liquid cooling equipment 400 or according to the specifications of the testing equipment. No specific limitation is made here.

[0079] For example, the testing device can perform single-item tests, single-medium multi-item combined tests, or multi-medium multi-item combined tests on the liquid cooling equipment 400. The testing device also includes a controller, and the first valve group 200, the second valve group 500, the gas supply component 100, and the liquid supply component 700 are electrically connected to the controller. The controller can control the operation of the first valve group 200, the second valve group 500, the gas supply component 100, and the liquid supply component 700.

[0080] The following explanation uses the pressure holding test as an example of a single test.

[0081] First, the testing device is connected to the liquid cooling equipment 400 via the first and second quick connectors. After connection, the controller connects the air supply inlet to the outlet of the first valve group 200 and the inlet of the second valve group 500 to the liquid collection outlet. The controller controls the air supply assembly 100 to supply air to the liquid cooling equipment 400 (e.g., by controlling an air compressor), causing the liquid medium in the liquid cooling equipment 400 to be discharged and flow into the liquid collection tank 800, thus emptying the liquid in the liquid cooling equipment 400. After the liquid in the liquid cooling equipment 400 flows into the liquid collection tank 800, the controller switches the connection between the inlet of the second valve group 500 and the return air outlet, allowing gas to circulate within the testing device and the liquid cooling equipment 400, purging the liquid in the liquid cooling equipment 400 and further emptying the liquid in the liquid cooling equipment 400.

[0082] After the liquid in the liquid cooling device 400 is emptied, the controller disconnects the inlet of the second valve group 500 from the outlets of all other second valve groups 500, effectively sealing the second valve groups 500. Simultaneously, the controller controls the air supply assembly 100 to continue supplying air to the liquid cooling device 400, increasing the air pressure within the liquid cooling device 400 to a set pressure. Once the air pressure in the liquid cooling device 400 reaches the set pressure and stabilizes, the air supply assembly 100 is shut off. Multiple pressure values ​​within the liquid cooling device 400 can be periodically or continuously monitored by the first pressure sensor to determine the pressure-holding effect of the liquid cooling device 400 based on changes in these pressure values, thus achieving a pressure-holding test of the liquid cooling device 400.

[0083] After the pressure holding test is completed, if it is necessary to fill the liquid cooling equipment 400, first connect the inlet end of the second valve group 500 to the return gas outlet end, so that the gas in the liquid cooling equipment 400 flows back to the gas supply assembly 100, thereby reducing the gas pressure in the liquid cooling equipment 400. Then connect the liquid supply inlet end to the outlet end of the first valve group 200, and connect the inlet end of the second valve group 500 to the return liquid outlet end, or connect the inlet end of the second valve group 500 to the liquid collection outlet end, so that liquid is filled into the liquid cooling equipment 400 through the liquid supply assembly 700. After filling is completed, the test device and the liquid cooling equipment 400 can be separated through the first quick connector and the second quick connector, ending the test operation on the liquid cooling equipment 400.

[0084] The following explanation uses the combined test of a single working fluid and multiple components, specifically the pressure holding and thermal resistance tests, as examples.

[0085] The test procedure for this pressure holding test is the same as that shown in the previous single test, and will not be repeated here. After the pressure holding test is completed, the controller connects the inlet end of the second valve group 500 to the return gas outlet end, so that the gas in the liquid cooling equipment 400 can flow back to the gas supply component 100 through the second pipeline and the second valve group 500 to reduce the gas pressure in the liquid cooling equipment 400.

[0086] The controller connects the liquid supply inlet to the outlet of the first valve group 200 and the inlet of the second valve group 500 to the return outlet. It also controls the liquid supply assembly 700 to supply liquid to the liquid cooling device 400 (e.g., controls the drive pump to work), so that the liquid supply assembly 700, the first valve group 200, the first pipeline, the liquid cooling device 400, the second pipeline, and the second valve group 500 can form a sealed liquid circuit, in which the liquid can circulate.

[0087] At this time, the power consumption of the electronic device can be controlled to the set power consumption. The temperature of the liquid in the circuit is detected by the temperature sensor 940, and the flow rate of the liquid in the circuit is detected by the flow sensor 950. The temperature inside the electronic device can be directly obtained by the software or sensor inside the electronic device. The thermal resistance test effect can be obtained based on the liquid temperature, the liquid flow rate and the temperature inside the electronic device.

[0088] If liquid is required to be stored in the liquid cooling device 400, after the thermal resistance test is completed, the test device and the liquid cooling device 400 can be directly separated through the first quick connector and the second quick connector to end the test operation on the liquid cooling device 400.

[0089] The following explanation uses the combined testing of multiple working fluids and multiple parameters, specifically thermal resistance and pH value testing, as examples.

[0090] When performing multi-propellant, multi-item combined tests, this can be achieved using multiple liquid supply components 700 of the liquid cooling device 400. For example, the multiple liquid supply components 700 include a first liquid supply component and a second liquid supply component. Thermal resistance testing of the liquid cooling device 400 can be performed using the first liquid supply component. The test procedure for this thermal resistance test is the same as that shown in the aforementioned single-propellant, multi-item combined test, and will not be repeated here.

[0091] After the thermal resistance test is completed, the controller can control the air supply component 100 to supply air to the liquid cooling device 400 to drain the liquid in the liquid cooling device 400. The steps for draining the liquid in the liquid cooling device 400 can be the same as the steps for draining the liquid in the liquid cooling device 400 in the pressure holding test described above, and will not be repeated here.

[0092] The liquid medium in the second liquid supply assembly can be deionized water. After the liquid in the liquid cooling device 400 is drained, the controller connects the inlet end of the first valve group 200 (which is connected to the outlet end of the second liquid supply assembly) to the outlet end of the first valve group 200, and the inlet end of the second valve group 500 to the outlet end of the second valve group 500 (which is connected to the inlet end of the second liquid supply assembly), or the inlet end of the second valve group 500 to the liquid collection outlet end. In this way, the second liquid supply assembly can supply deionized water to the liquid cooling device 400 to flush the inside of the liquid cooling device 400 and reduce the residue of the coolant medium. The flushed deionized water returns to the second liquid supply assembly or is collected in the liquid collection tank 800. After flushing the liquid cooling device 400 through the second liquid supply assembly, the liquid in the liquid cooling device 400 can be drained again through the liquid draining step, which will not be described in detail here.

[0093] After the liquid in the liquid cooling device 400 is emptied, the controller can connect the outlet of the first liquid supply component to the first valve group 200, and the second valve group 500 to the inlet of the first liquid supply component, so as to provide clean liquid medium to the liquid cooling device 400 through the first liquid supply component. Alternatively, the multiple liquid supply components may include a third liquid supply component. The controller can connect the outlet of the third liquid supply component to the first valve group 200, and the second valve group 500 to the inlet of the third liquid supply component, so as to control the third liquid supply component to provide clean liquid medium to the liquid cooling device. After adding clean liquid medium to the liquid cooling device 400, the clean liquid medium can be allowed to stand in the liquid cooling device 400 for a set time. After the set time of standing, the liquid medium after standing is collected for pH value detection to complete the test. After the test is completed, the test device and the liquid cooling device 400 can be directly separated through the first quick connector and the second quick connector to end the test operation on the liquid cooling device 400.

[0094] It is understood that the above-described operations and tests that the testing device can perform are merely exemplary. The specific operations and tests that the testing device can perform can be set according to the experience of those skilled in the art, or according to the operation and testing requirements of the liquid cooling equipment 400, and are not specifically limited here.

[0095] For example, such as Figure 2 As shown, the outlet end of the first valve group 200 can also be connected to the inlet end of the liquid collection tank 800.

[0096] The outlet end of the first valve group 200 can be connected to one end of the first pipeline 300, and the outlet end of the first valve group 200 can also be connected to the inlet end of the liquid collection tank 800. For example, the first valve group 200 has two outlet ends. In one case, the outlet end of the gas supply component 100 can be connected to the first pipeline 300 through the first valve group 200, and in another case, the outlet end of the gas supply component 100 can be directly connected to the inlet end of the liquid collection tank 800 through the first valve group 200. In this way, when the gas mixed with liquid returns to the gas storage tank 110, the first valve group 200 can connect the gas storage tank 110 and the liquid collection tank 800 to discharge the liquid in the gas storage tank 110, reduce the occurrence of liquid when supplying gas to the liquid cooling equipment 400, and improve the stability and reliability of the testing device.

[0097] Alternatively, the outlet of the liquid supply assembly 700 can be connected to the first pipeline 300 via the first valve group 200 in one scenario, and directly connected to the inlet of the collection tank 800 via the first valve group 200 in another scenario. This allows the liquid in the liquid supply assembly 700 to be directly discharged via the first valve group 200 when not connected to the liquid cooling equipment 400, facilitating maintenance and cleaning of the testing device and improving operational convenience.

[0098] When the first valve group 200 includes a first multi-way valve 210, the first multi-way valve 210 may also have a third outlet end, which is connected to the inlet end of the liquid collection tank 800. Multiple first inlet ends can also be selectively connected to the third outlet end. It is understood that the above-described connection method between the outlet end of the first valve group 200 and the inlet end of the liquid collection tank 800 is merely exemplary. The specific connection method can be set based on the experience of those skilled in the art, or based on the specific component structure of the testing device, as long as the fluid medium flowing through the first valve group 200 can flow into the liquid collection tank 800. The specific connection method is not specifically limited here.
