Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a data center testing device, testing method, and data center testing system. Background Technology

[0002] With the rapid development of data centers, high energy consumption has become an issue that cannot be ignored in the development of the data center industry. From the perspective of the entire data center industry, liquid cooling technology is currently the most feasible solution to effectively reduce data center energy consumption.

[0003] Liquid cooling technology uses liquid cooling to dissipate heat from heat-generating components such as servers and processors. However, there are some bottlenecks in testing technology when promoting and applying liquid cooling technology. For example, in the process of testing and verifying liquid cooling technology, traditional testing equipment relies on air cooling, which cannot meet the requirements of liquid cooling testing. Therefore, there is an urgent need for new testing equipment that can simulate the actual heat generation and power consumption of real servers in order to test the data center under test. In addition, since the special refrigerants used in liquid cooling technology are often special liquids such as highly volatile and expensive fluorinated liquids, how to recycle and reuse these special liquids to avoid waste or pollution is also a requirement that the new testing equipment should meet.

[0029] Before introducing the technical solutions provided in the various embodiments of this application, some specialized terms involved in the embodiments of this application will be introduced and explained.

[0030] A data center, also known as an Internet Data Center (IDC), is a globally collaborative network of specific devices used to transmit, accelerate, display, compute, and store data information on the Internet infrastructure. Simply put, a data center is a place that hosts various types of data online.

[0031] Testing equipment refers to simulation devices (or simulated servers, simulated loads) designed to test the performance of a system (such as a data center system). These devices can achieve the same electrical power as in a real-world scenario and can be used to test supporting infrastructure systems such as electrical systems and HVAC systems. For example, in a data center system testing scenario, testing equipment simulates the actual heat generation and power consumption of the data center device under test, such as a real server, to detect the effectiveness of liquid cooling and the electrical safety of data center wiring, providing a data foundation and testing methods for assessing the availability of the data center system.

[0032] Liquid cooling technology utilizes a liquid medium to exchange heat with heat-generating devices through direct or indirect contact, and then the heat is transferred away by the cooling liquid. Specifically, liquid cooling technology is divided into two types: direct cooling and indirect cooling. Direct cooling includes methods such as jet impact, spray cooling, and immersion cooling, while indirect cooling mainly refers to macroscopic circulating water cooling and cold plate liquid cooling. Immersion liquid cooling, among the aforementioned direct cooling methods, has become the mainstream trend in the development of heat dissipation technology for data center servers. Therefore, the test equipment provided in the embodiments of this application adopts the immersion liquid cooling method. Immersion liquid cooling refers to using a liquid such as fluorinated liquid or ethylene glycol (the liquid in this embodiment is not limited) as the heat transfer medium, directly immersing the heat-generating device in the coolant, relying on the liquid flow to circulate and remove the heat generated by the device's operation. It should be noted that the aforementioned heat-generating device can be a specific device, such as, but not limited to, a server or switch; it can also be a specific component, such as, but not limited to, a chip (such as a CPU, GPU, ASIC, etc.), memory, or network card. For information on other types of liquid cooling technologies besides immersion liquid cooling, please refer to existing related materials.

[0033] Figure 1a , Figure 1b and Figure 2 This application shows a schematic diagram of the structure of a data center testing device according to an embodiment of the present application. Specifically, Figure 1a The diagram shows the front structure of the test equipment in the data center. Figure 1b What is shown is with Figure 1a A side view diagram of the corresponding data center test equipment; Figure 2 Schematic diagrams 100 and 200 respectively show the... Figure 1a , Figure 1b A schematic diagram of the floor plan of the corresponding data center testing equipment. (See attached diagram.) Figure 1a , Figure 1b and Figure 2 As shown, an embodiment of the data center testing equipment provided in this application includes: a liquid cooling box 1, a simulation device 2, and a control device 3. Wherein,

[0034] The liquid-cooled tank 1 has a liquid circulation device 11 for connecting to the liquid cooling system of the data center under test (not shown in the figure). The liquid cooling system of the data center can be, but is not limited to, a CDU (chill water distribution unit), a device that enables smaller, more efficient, and more precise liquid cooling within a data center. Furthermore, the data center may also have a liquid storage system (not shown in the figure). When the data center test is initiated, the liquid cooling system operates, and the liquid in the storage system (not shown in the figure) flows into the liquid cooling system. After being cooled and converted into a colder liquid by the liquid cooling system, it can be injected into the liquid-cooled tank 1 through the liquid circulation device 11 to supply liquid to the liquid-cooled tank 1. Additionally, the liquid circulation device 11 can also promote liquid circulation within the liquid-cooled tank. The specific implementation of the liquid circulation device 11 and the liquid supply from the liquid cooling system to the liquid-cooled tank 1 will be described in detail below. The liquid stored in the liquid storage system of the aforementioned data center can be a non-conductive liquid with good heat exchange performance and that needs to be recycled. For example, the liquid can be a fluorinated liquid used in engineering, ethylene glycol, or a widely used synthetic oil or mineral oil. As a preferred example, this example preferably selects a fluorinated liquid.

[0035] Simulation device 2, installed inside liquid-cooled tank 1, is used to simulate the data center device under test immersed in liquid. In the above, the data center device under test can refer to electronic devices such as servers and switches, or electronic components such as processors and memory; this is not limited here. A server is a type of computer that runs faster and has higher power than a regular computer. Servers provide computing or application services to other clients on a network, possessing high-speed computing power, long-term reliable operation, powerful I / O (input / output) external data throughput capabilities, and better scalability. See [link to specific achievable technical solution] for details. Figure 1bAs shown, the simulation device 2, used to simulate the equipment of a data center under test immersed in liquid, can be modularly composed of multiple heating resistors 21. In layman's terms, the simulation device in this embodiment can also be called a simulated load or a test dummy load. The heating resistors 21 can be of constant resistance or constant power. Using this simulation device 2, various power requirements for testing the data center under test can be simulated, such as 12KW, 6KW, 2KW, 1KW, 180KW, etc. Currently, the simulation device can support a maximum power of 360KW, which ensures full-load testing of the liquid cooling system of the data center. Furthermore, the modular simulated load can be flexibly replaced and disassembled, making it easily applicable to various types of liquid cooling systems. When liquid is injected into the liquid cooling tank 1, the simulation device 2 can be fully or partially immersed in the liquid. For example, the liquid cooling tank 1 has multiple electrical connection sockets, and the user can insert heating resistors 21 into at least some of these sockets according to actual needs. If the size of the data center under test is reduced, some heating resistors 21 can be removed.

[0036] Control device 3 is used to electrically connect to the electrical control system of the data center under test (not shown in the figure), send test commands to the electrical control system of the data center under test, so that the liquid cooling system of the data center under test can work to supply liquid to the liquid cooling tank 1 through the liquid circulation device 11 and promote the circulation of liquid in the liquid cooling tank 1, control the simulation device 2 to work to simulate test scenarios of various power devices, and monitor the test data generated during the test.

[0037] In practice, the aforementioned control device 3 is a control device installed within the testing equipment, for example, a device with an interactive interface. Figure 1a or Figure 2 The control panel 31, shown is an interactive interface. The control device 3 can send test commands to the electrical control system of the data center under test based on a user-triggered test start command. For example, see... Figure 1aAs shown, the user can trigger a test start command through the interactive interface 31 of the control device 3, thereby causing the control device 3 to send test commands to the electrical control system of the data center under test and control the operation of the liquid cooling system of the data center under test. Furthermore, during the triggering of the test start command, the user can also input the target power through interactive methods such as voice, keyboard, and touch provided by the interactive interface. Correspondingly, when responding to the user-triggered test start command, the control device 3 can acquire the target power and control the simulation device 2 to simulate the test scenario of the target power. The target power can be 12KW, 6KW, 180KW, etc. Further, after controlling the simulation device 2 to simulate the corresponding target power test scenario, the control device 3 can monitor the test data generated during the test through sensors (such as temperature sensors and voltage sensors) installed in the test device. The test data may include, but is not limited to, the power supply parameters (such as voltage and current) of the electrical control system of the data center under test, and the cooling parameters (such as the liquid temperature flowing into the liquid cooling tank 1 and the liquid temperature returning to the liquid cooling system) of the data center under test. For details on the specific implementation of monitoring and testing data generated during the testing process, please refer to the relevant content below.

[0038] When the liquid cooling system of the data center under test is working, the liquid cooling tank 1 is connected to the liquid cooling system of the data center under test, and the liquid circulates within the liquid cooling tank and the liquid cooling system. The specific circulation process is as follows: When the liquid cooling system is working, the cooler liquid in the liquid cooling system flows into the liquid cooling tank 1 through the liquid circulation device 11 to supply liquid to the liquid cooling tank 1, thus immersing it in the simulation device 2; further, when the test begins, the test control simulation device 2 is activated, and the simulation device 2 will generate heat, causing its internal temperature to rise. At this time, the cooler liquid can carry away the heat from the simulation device 2 and become a warmer liquid. The warmer liquid flows to the liquid cooling system, is cooled by the liquid cooling system (such as the evaporator in the liquid cooling system), and then enters the liquid cooling tank, thus completing the cycle.

[0039] Considering that simulation device 2 only generates heat when undertaking testing tasks, and therefore needs to be immersed in liquid for heat exchange, the liquid cooling tank 1 can be empty at the end of the simulation device 2's testing task. If the liquid in the liquid cooling tank 1 is then directly recycled to the data center's liquid cooling system, and subsequently, if simulation device 2 needs to be switched to the next power test point within a relatively short period, liquid must be supplied to the liquid cooling tank 1 again through the data center's liquid cooling system. This would undoubtedly increase the liquid supply time and make it inconvenient to process the liquid in the liquid cooling tank 1 during testing to ensure the liquid level meets testing requirements. Therefore, if... Figure 2 As shown in the diagram, the data center testing equipment provided in this embodiment also includes a liquid storage tank 4 and a liquid storage control device 5; wherein,

[0040] The liquid storage tank 4 is connected to the liquid cooling tank 1; the liquid storage tank can be used to temporarily store liquid.

[0041] Liquid storage control device 5 is electrically connected to the control device 3. When the control device 3 issues a recycling command, it operates in recycling mode to recycle the liquid in the liquid cooling tank to the liquid storage tank 4. It is also used to operate in control mode when the control device 3 issues a liquid control command during the test to control the amount of liquid cooling in the liquid cooling tank 1 to meet the test requirements.

[0042] The liquid storage tank can be integrated with the liquid cooling tank and installed within a single test equipment housing. Alternatively, the liquid storage tank can be detachably installed within the test equipment housing.

[0043] In practical implementation, the aforementioned liquid storage tank 4 can be connected via, for example... Figure 1b or Figure 2 The return liquid line 51 and supply liquid line 54 shown are connected to the liquid cooling tank 1. When it is determined that the simulation device 2 does not need to undertake the test task (e.g., the test is over), the liquid in the liquid cooling tank 1 can be temporarily stored (or recovered) to the storage tank 4 through the return liquid line 51; when the simulation device 2 undertakes the test task (e.g., the test is started) and detects that the liquid volume in the liquid cooling tank 1 does not meet the test requirements, the liquid in the storage tank 4 can be directly supplied to the liquid cooling tank 1 through the supply liquid line 54 to replenish the liquid in the liquid cooling tank 1. The above-described recovery of the liquid in the liquid cooling tank 1 to the storage tank 4 and supply of the liquid in the storage tank 4 to the liquid cooling tank 1 can be achieved by, for example Figure 2 The liquid storage control module 50 shown in the diagram controls the process. The aforementioned return liquid line 51, supply liquid line 54, and liquid storage control module 50 can be included within the liquid storage control device 5; that is, the liquid storage control device 5 includes the liquid storage control module 50, the return liquid line 51, and the supply liquid line 54.

[0044] The liquid storage control module 50 is electrically connected to the control device 3. When the control device 3 issues a recycling command, it operates in recycling mode to recycle the liquid in the liquid cooling tank to the liquid storage tank 4. It is also used to operate in regulation mode when the control device 3 issues a liquid regulation command during the test to regulate the amount of liquid cooling in the liquid cooling tank 1 to meet the test requirements.

[0045] One end of the aforementioned return liquid pipeline 51 is connected to the liquid cooling tank 1, and the other end is connected to the liquid storage tank 4. For example, see... Figure 1b or Figure 2As shown in the structure, one end of the return liquid pipeline 51 can be connected to the liquid cooling tank 1 through the liquid circulation device 11. Specifically, it can be connected to the liquid cooling tank 1 through the outlet pipe 112 included in the liquid circulation device 11, while the other end can be connected to the storage tank 4 through the connection port (not shown in the figure) opened on the top of the storage tank 4. Furthermore, in order to ensure that the liquid in the liquid cooling tank 1 can be smoothly recovered to the storage tank 4 through the return liquid pipeline 51, and at the same time ensure that the liquid in the storage tank 4 does not flow back to the liquid cooling tank 1 during the recovery of the liquid in the liquid cooling tank 1, the above-mentioned storage control device 5 also includes a return liquid pump 52 and a first electric valve 53 (see Figure 3 and Figure 1b A return pump 52, installed on the return pipeline 51 and electrically connected to the control device 3, is activated when the control device 3 issues a recovery command to recover the liquid in the liquid cooling tank 1 to the storage tank 4. A first electric valve 53, installed on the return pipeline 51 and electrically connected to the control device 3, is opened when the control device 1 issues a recovery command, allowing the liquid in the liquid cooling tank 1 to be recovered to the storage tank 4 and preventing the liquid in the storage tank 4 from flowing back to the liquid cooling tank 1. In one specific embodiment, the control device 3 can issue a recovery command when it detects that the test meets preset conditions, causing the storage control module 50 to operate in recovery mode, thereby controlling the return pump 52 and the first electric valve 53 installed on the return pipeline 52 to start working. The test meeting preset conditions may include, but are not limited to, at least one of the following: the test duration reaches a preset duration, the test requirements meet preset requirements, the liquid volume in the liquid cooling tank exceeds a threshold, or a user triggers a return operation.

[0046] The same return liquid line 51, one end of the aforementioned supply liquid line 54 is connected to the liquid cooling tank 1, and the other end is connected to the storage tank 4. For example, see... Figure 1b or Figure 2As shown in the structure, one end of the liquid supply pipe 54 can be connected to the liquid cooling tank 1 through the liquid circulation device 11 installed inside the liquid cooling tank 1. Specifically, it can be connected to the liquid cooling tank 1 through the water inlet pipe 111 included in the liquid circulation device 11, while the other end can be connected to the storage tank 4 through the connection port (not shown in the figure) opened at the bottom of the storage tank 4. Furthermore, in order to detect the liquid volume in the liquid cooling tank during the test, and to ensure that the liquid in the storage tank 2 can be smoothly supplied to the storage tank 1 through the liquid supply pipe 54 when the liquid volume in the liquid cooling tank 1 does not meet the test requirements, while simultaneously ensuring that the liquid in the liquid cooling tank 1 does not flow back into the storage tank 4 during the liquid supply process, the aforementioned liquid control device 5 also includes a liquid level detection device (not shown in the figure), a liquid supply pump 55, and a second electric valve 56. The liquid level detection device, electrically connected to the control device 3, can be used to detect the liquid volume in the liquid cooling tank. In one specific embodiment, the liquid level detection device can be, but is not limited to, a liquid level sensor. The liquid level sensor can be installed in at least one of the liquid cooling tank 1 and the liquid storage tank 4. As a preferred example, liquid level sensors can be installed in both the liquid cooling tank 1 and the liquid storage tank 4 to detect changes in the liquid volume in the liquid cooling tank 1 and the liquid storage tank 4. Specifically, the types of liquid level sensors mentioned above can be, but are not limited to: motor-type liquid level control sensors, UQK / GSK type liquid level control sensors, photoelectric liquid level control sensors, and pressure type liquid level control sensors. The principles of liquid level detection by the above-described types of liquid level sensors can be found in existing materials and will not be elaborated here. A liquid supply pump 55 is installed on the liquid supply pipeline 54 and electrically connected to the control device 3. It is used to start working when the control device 3 issues a liquid regulation command based on the liquid level detection device detecting that the liquid volume does not meet the test requirements, so as to supply liquid from the storage tank 4 to the liquid cooling tank 1. For example, after the current test power is completed, since the liquid originally injected into the liquid cooling tank 1 has been recovered into the storage tank 4, if the simulation device 2 is detected to switch to the next power for testing, the liquid level sensor installed in the liquid cooling tank 1 will detect that the current liquid level in the liquid cooling tank 1 is less than a set threshold. The amount of liquid in the liquid cooling tank 1 is insufficient to submerge the simulation device 2, thus failing to meet the test requirements. Therefore, the storage tank 4 needs to supply liquid to the liquid cooling tank 1. At this time, the control device 3 can issue a liquid regulation command, causing the storage control module 50 to operate in regulation mode, controlling the liquid supply pump 55 to start working, and simultaneously controlling the second electric valve 56 to start working. The second electric valve 56 is installed on the liquid supply pipeline 54 and electrically connected to the control device 3. It is used to open when the control device 3 issues a liquid regulation command, allowing the liquid in the storage tank 4 to be supplied to the liquid cooling tank 1 and preventing the liquid in the liquid cooling tank 1 from flowing into the storage tank 4.

[0047] It should be noted that the aforementioned return pump 52 and supply pump 55 can be, but are not limited to, peristaltic pumps and hydraulic pumps. Electric valves (such as the first electric valve 53 and the second electric valve 56) are devices that use electric actuators to control the valve, thereby realizing the opening and closing of the valve. They can be divided into upper and lower parts: the upper part is the electric actuator, and the lower part is the valve. The types of electric valves can be, but are not limited to, rotary electric valves and linear electric valves. For a detailed description of the electric valve types shown above, please refer to the existing content. The aforementioned first electric valve 53 and second electric valve 54 are both one-way valves to ensure the unidirectional flow of liquid circulation during the test. For example, see... Figure 1b or Figure 2 As shown, the first electric valve 53 and the second electric valve 54 ensure that the liquid circulates between the liquid cooling tank 1 and the storage tank 4 in a single direction: "liquid cooling tank 1 -> return pipe 51 -> storage tank 4 -> supply pipe 54 -> liquid cooling tank 1". The specific positions of the return pump 52 and the first electric valve 53 on the return pipe 51, and the specific positions of the supply pump 55 and the second electric valve 56 on the supply pipe 54, can be flexibly set according to actual conditions, and this embodiment does not impose specific limitations on them. In addition, the liquid circulation device 11 of the liquid cooling tank 1 described above may include other components such as sensors and shock absorbers, in addition to the inlet and outlet pipes. For a description of the specific components and their functions included in the liquid circulation device 11, please refer to the relevant content below. Furthermore, it should be added that during operation, the principle of "opening the valve first and then starting the pump" and "closing the pump first and then closing the valve" should be followed. For example, after receiving a recovery command from the control device, the liquid storage control device first opens the first electric valve and then starts the return pump; after recovery is complete, the return pump is shut off first and then the first electric valve is closed. Similarly, after receiving a liquid regulation command from the control device, the liquid storage control device first opens the second electric valve and then starts the supply pump; after supplying liquid is complete, the supply pump is shut off first and then the second electric valve is closed. This is done to prevent the pump from stalling.

[0048] Furthermore, the liquid storage tank 4 can also have a refrigeration mechanism (not shown in the figure). This way, at the end of the test, after the hotter liquid in the liquid-cooled tank 1 is recovered to the liquid storage tank 4, the refrigeration mechanism can cool the hot liquid for use in the next test. In addition, the refrigeration mechanism can also reduce liquid evaporation. The operation of the above-mentioned refrigeration mechanism can be controlled by the liquid storage control module 50.

[0049] Figure 3 A schematic diagram showing the connection sequence between the components of the liquid storage control device 5 is shown.

[0050] Furthermore, to avoid obstacles encountered during the process of recovering liquid from the liquid cooling tank 1 to the storage tank 4 or supplying liquid from the storage tank 4 to the liquid cooling tank 1, the data center testing equipment provided in this embodiment, such as... Figure 1b As shown in the diagram, the liquid storage tank 4 is also equipped with an exhaust device 41. The exhaust device 41 is electrically connected to the control device 3 and is activated when the control device 3 issues a return liquid command or a liquid regulation command, allowing the liquid storage tank 4 to communicate with the outside atmosphere. This ensures that the pressure inside the liquid storage tank 4 is balanced with the outside atmospheric pressure, facilitating smooth liquid recovery or supply. Furthermore, to prevent liquid evaporation after the test, the exhaust device 41 is also activated to close when the control device 3 issues a test completion command, thus sealing the liquid storage tank 4. For example, the control device 3 can issue a test completion command when it detects that a user has triggered a test end operation, or when it detects that the test duration has reached a set duration, or when it determines that the liquid in the liquid cooling tank has been recovered into the storage tank. This causes the exhaust device 41 to close based on the test completion command, sealing the storage tank 4 and preventing liquid evaporation.

[0051] Furthermore, to achieve liquid recycling, the data center testing equipment provided in this embodiment also includes a discharge pipeline (not shown in the figure) and a drain valve 6. The discharge pipeline is located at the bottom of the liquid cooling tank 1 and the liquid storage tank 4. Specifically, the discharge pipeline can be flexibly located at any position at the bottom of the liquid cooling tank 1 and the liquid storage tank 4, depending on the actual situation; no limitation is made here. One end of the discharge pipeline can be connected to the liquid cooling tank 1 and the liquid storage tank 4, and the other end can be connected to the data center's liquid storage system. The drain valve 6 is located on the discharge pipeline and is used to open at the end of the measurement to recover the liquid in the liquid cooling tank 1 and the liquid storage tank 4 into the liquid storage system of the data center under test, ensuring the recycling and reuse of the liquid.

[0052] The aforementioned drain valve 6 is a specialized valve for venting at high points and draining at low points in a pipeline. Venting at high points prevents non-condensable gases from creating air resistance in the pipeline, while draining at low points prevents liquid accumulation from creating resistance to gas flow and also prevents the liquid in the pipeline from freezing at low points. Based on the above, in this embodiment, the drain valve 6 can also be used to recover the liquid accumulated at the lower levels of the liquid cooling tank 1 and the storage tank 4 to the liquid storage system of the data center under test, thereby cleaning the pipeline and ensuring that the liquid is completely recovered without any residual liquid.

[0053] The technical solution provided in this embodiment includes a data center testing device comprising a liquid-cooled tank with a liquid circulation device. This liquid circulation device can be connected to the liquid cooling system of the data center under test, enabling the liquid cooling system to supply liquid to the liquid-cooled tank via the liquid circulation device. Furthermore, a simulation device is also installed inside the liquid-cooled tank to simulate the equipment of the data center under test immersed in liquid. This simulation device can simulate various operating scenarios, meeting the needs of diverse power testing scenarios. In addition, the testing device includes a control device electrically connected to the electrical control system of the data center under test. This control device sends test commands to the electrical control system of the data center under test, causing the liquid cooling system of the data center under test to operate, supplying liquid to the liquid-cooled tank via the liquid circulation device and promoting liquid circulation within the tank. Furthermore, it can control the simulation device to simulate various operating conditions corresponding to test scenarios and monitor the test data generated during the test. Automatic monitoring of test data makes testing simpler, more intelligent, and easier to maintain. Overall, the testing device provided in this embodiment has a high degree of intelligence and can meet the needs of various testing scenarios. Therefore, when using the testing equipment provided in this application embodiment to test the data center, the testing process can be simplified, and various working condition scenarios can be tested on the data center, which improves the accuracy of the test.

[0054] The liquid circulation device 11 of the liquid-cooled box 1 described above will be explained in detail below.

[0055] Figure 4 A schematic diagram showing the connection sequence of the components of the liquid circulation device 11 in the liquid cooling tank 1 is shown. (See also...) Figure 1a , Figure 1b , Figure 2 as well as Figure 4 The structure shown, in the data center testing equipment provided in this embodiment, includes a liquid circulation device 11 that may include: an inlet pipe 111, an outlet pipe 112, and a sensor 113.

[0056] The aforementioned water inlet pipe 111 has an inlet 111a at one end and is connected to the liquid cooling tank 1 at the other end. The inlet 111a is used to connect to the liquid cooling system supply terminal of the data center under test (not shown in the figure). In a specific implementation, a connection port (not shown in the figure) can be opened at the bottom of the liquid cooling tank 1, through which the other end of the water inlet pipe 111 can be connected to the liquid cooling tank 1. In addition, a first valve (not shown in the figure) can be provided at the inlet 111a of the water inlet pipe 11 to control the opening or closing of the inlet 111a.

[0057] The aforementioned water outlet pipe 112 has an outlet 112b at one end and is connected to the liquid cooling tank 1 at the other end. The outlet 112b is used to connect to the return end of the liquid cooling system of the data center under test (not shown in the figure). In a specific implementation, a connection port (not shown in the figure) can be opened on the top of the liquid cooling tank 1, and the other end of the water outlet pipe 112 can be connected to the liquid cooling tank 1 through this connection port. In addition, a second valve (not shown in the figure) can be installed at the outlet 112b of the water outlet pipe 12 to control the opening or closing of the outlet 112b.

[0058] The aforementioned sensor 113, see [link / reference] Figure 1b and Figure 4 As shown, the device may include at least one of the following: a pressure sensor 1131, a flow sensor 1132, and a temperature sensor 1133. The number of each of the pressure sensor 131, flow sensor 132, and temperature sensor 133 is at least one. Specifically, at least one pressure sensor 1131 is electrically connected to the control device 3 and is used to measure the pipeline pressure of at least one of the inlet pipeline 111 and the outlet pipeline 112. In practical applications, the inlet pipeline 111 and the outlet pipeline 112 provided in this embodiment can normally withstand a pipeline pressure of 8 Bar, and the ultimate test pressure is 1.5 times the normally withstandable pipeline pressure. At least one flow sensor 1132 is electrically connected to the control device 3 and is used to measure the liquid flow rate in at least one of the inlet pipeline 111 and the outlet pipeline 112. During the process of the liquid system supplying liquid to the liquid cooling tank 1, the amount of liquid injected into the liquid cooling tank 1 can be detected by at least one of the flow sensor and the liquid level sensor installed in the liquid cooling tank 1 to determine whether the required amount has been reached. In the solution provided in this embodiment, the pipe diameters of the aforementioned inlet pipe 111 and outlet pipe 112 can be set to, but are not limited to, 80mm, 70mm, etc. When the pipe diameter is set to 80mm (i.e., DN80), the liquid flow rate in the pipe is between 1 and 60m³. 3 The flow rate is recommended to be maintained at around 3 m / s between [a certain value] / h. At least one temperature sensor 1133, electrically connected to the control device 3, is used to measure the liquid temperature inside the liquid cooling tank 1. In specific implementation, the liquid temperature inside the liquid cooling tank 1 is related to the test scenario. For example, when the test scenario temperature is between 30°C and 38°C, the inlet liquid temperature from the liquid cooling system of the data center entering the liquid cooling tank 1 is 5°C to 50°C, and the temperature difference between the inlet and outlet liquids inside the liquid cooling tank is about 10°C.

[0059] Further, see Figure 4As shown, to prevent damage to the inlet pipe 111 and outlet pipe 112 when the test equipment encounters vibration, the liquid circulation device 11 further includes a first shock absorber 114a and a second shock absorber 114b. Specifically, the first shock absorber 114a is provided at the inlet 111 to connect to the liquid supply end of the liquid cooling system; the second shock absorber 114b is provided at the outlet 112b to connect to the liquid return end of the liquid cooling system. The type of the shock absorbers (such as the first shock absorber 114a and the second shock absorber 114b) can be, but is not limited to, hydraulic shock absorbers, pneumatic shock absorbers, and variable damping shock absorbers.

[0060] Further, see also Figure 4 As shown, to alleviate the pressure at the inlet 111a of the inlet pipe 111 and prevent pressure loss in the testing equipment, the liquid circulation device 11 further includes a pressure reducing valve 115. This pressure reducing valve 115 is installed on the inlet pipe 111 and located downstream of the first shock absorber 114a at the inlet. Specifically, the pressure reducing valve 115 is a valve that reduces the inlet pressure to a desired outlet pressure through adjustment, and automatically maintains a stable outlet pressure by relying on the energy of the medium itself. Specifically, from a fluid mechanics perspective, the pressure reducing valve is a throttling element with variable local resistance; that is, by changing the throttling area, the flow velocity and kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of pressure reduction. On the section of the inlet pipe 111 between the first shock absorber 114a and the pressure reducing valve 115, a first pressure sensor 1131a, a first flow sensor 1132a, and a first temperature sensor 1133a may be provided to measure the pipe pressure of the inlet pipe 111, the liquid flow rate in the inlet pipe 111, and the temperature of the liquid flowing from the liquid cooling system of the data center into the liquid cooling tank 1 through the inlet pipe 111.

[0061] Further, see also Figure 4 The aforementioned liquid circulation device 11 may further include an outlet electric valve 116. This outlet electric valve 116 is installed on the outlet pipe 112. On the section of the outlet pipe 112 between the outlet electric valve 116 and the second shock absorber 114b, a second pressure sensor 1131b, a second flow sensor 1132b, and a second temperature sensor 1133b may be installed to measure the pipe pressure of the outlet pipe 112, the liquid flow rate within the outlet pipe 112, and the outlet liquid temperature of the liquid cooling tank 1 and / or the storage tank 4 when the liquid is recycled to the liquid cooling system of the data center through the outlet pipe 112.

[0062] Furthermore, such as Figure 1bAs shown, at least one air vent valve 117 may also be installed on the water outlet pipe 112.

[0063] It should be noted that, in some embodiments, the temperature sensors installed on the inlet pipe 111 and outlet pipe 112 can be used to monitor the cooling parameters of the liquid cooling system of the data center during the test. These cooling parameters can be parameters that characterize the cooling effect of the liquid cooling system. For example, during the test, the temperature of the liquid flowing into the liquid cooling system can be detected by the second temperature sensor 1133b installed on the outlet pipe 112; simultaneously, the temperature of the liquid flowing into the liquid cooling tank (i.e., the temperature of the liquid flowing out of the liquid cooling system) can be monitored by the first temperature sensor 1133a installed on the inlet pipe 111. Furthermore, the cooling parameters of the liquid cooling system of the data center under test can be measured based on the difference between the liquid temperature of the outlet pipe 112 and the liquid temperature of the inlet pipe 111.

[0064] Based on the above, Table 1 below shows some technical parameters of the data center testing equipment provided in this embodiment:

[0065] Table 1 Technical parameters of the testing equipment

[0066]

[0067]

[0068] It should be noted that the data center testing equipment provided in this embodiment, in addition to the various components described above such as the liquid cooling box, simulation device, control device, liquid storage tank, liquid storage control device, and sensors, may also include other components, such as... Figure 1b As shown, the data center testing equipment may also include indicator lights 7, air switches 8, wheels 9, power interfaces 10, etc. The air switch 8 (also known as an air circuit breaker) is an automatic circuit breaker with automatic sectionalizing function and arc extinguishing in air. It can automatically disconnect when the current or voltage in the circuit of the testing equipment exceeds the rated current or rated voltage, thus protecting the testing equipment from short circuits, severe overloads, and undervoltage. Indicator lights 7 serve a warning function, such as indicating the current testing status (e.g., test completed, test started) and whether the testing equipment is overloaded. Furthermore, the testing equipment may also include sensors for detecting the voltage and current of the simulation device 2, so as to indirectly monitor the power supply parameters of the electrical control system of the data center under test when the simulation device is operating at full power.

[0069] During the testing process using the data center testing equipment provided in this embodiment, please refer to... Figure 1b , Figure 3and Figure 4 As shown, the testing using the data center testing equipment provided in this embodiment can be achieved through the following steps:

[0070] 1) Turn on the simulation device 2 to simulate the maximum power switch corresponding to the data center equipment under test, and set the power limit value on the interactive interface provided by the control device 3.

[0071] 2) Connect the test equipment to the liquid cooling system of the data center (not shown in the figure). Specifically, connect the inlet 111a of the test equipment's inlet pipe 111 to the liquid supply end of the data center's liquid cooling system, and connect the outlet 112b of the test equipment's outlet pipe 112 to the liquid return end of the data center's liquid cooling system; and check to ensure that the connections between the inlet 111a of the inlet pipe 111 and the liquid supply end of the liquid cooling system, and the connections between the outlet 112b of the outlet pipe 112 and the liquid return end of the liquid cooling system are tight and leak-free. Vibration dampers are installed at both the inlet 111a and the outlet 112b.

[0072] 3) Check whether the settings for the test equipment startup conditions and alarm thresholds are correct.

[0073] 4) Check if the liquid storage tank 4 is full. If it is, drain the liquid to ensure it can hold the liquid in the liquid cooling tank 1. Specifically, when draining the liquid from the tank 4, the liquid can be returned to the data center's liquid cooling system via the outlet pipe 112. Furthermore, ensure the exhaust device 41 on the tank 4 is functioning properly, allowing the tank 4 to communicate with the outside atmosphere.

[0074] 5) Start the test. During the start-up test, the components of the test equipment involve the following action scenarios:

[0075] 5.1) Upon initial test startup, the simulation device 2 inside the liquid cooling tank is activated to simulate the test scenario corresponding to the target power set by the user. Simultaneously, the exhaust device 41 on the liquid storage tank 4 opens, connecting the liquid storage tank 4 to the outside atmosphere. The data center's liquid cooling system begins operation, and liquid from the data center's storage system flows into the liquid cooling system. After being converted into a cooler liquid, this cooler liquid is injected into the liquid cooling tank 1 through the inlet pipe 111 to supply liquid to the liquid cooling tank 1. During the liquid injection process into the liquid cooling tank 1, the liquid level in the liquid cooling tank 1 continuously rises to submerge the simulation device 2. The pressure, flow rate, and temperature of the liquid entering the inlet pipe 111 are measured by the first pressure sensor 1131a, the first flow sensor 1132a, and the first temperature sensor 1133a installed on the inlet pipe 111, and displayed normally by the corresponding pressure gauge, liquid cooling flow meter, and temperature gauge. The pressure gauge, flow meter, and temperature gauge are not shown in the figure. Additionally, the amount of liquid injected into the liquid cooling tank 1 can be detected by at least one of the liquid level sensor and the first flow sensor 1132a installed inside the liquid cooling tank 1, to determine whether the liquid injection into the liquid cooling tank 1 is complete. It should be noted that during the liquid cooling system's supply of liquid to the liquid cooling tank 1 in the data center, to prevent excessively high gas pressure inside the liquid cooling tank 1 from hindering the liquid injection, the first electric valve 53 installed on the return pipe 51 can be opened to connect the liquid cooling tank 1 with the storage tank 4. Simultaneously, the exhaust device 41 installed on the storage tank 4 can be opened to connect the storage tank 4 with the outside atmosphere, thereby maintaining a balance between the gas inside the storage tank 4 and the liquid cooling tank 1 and the external gas pressure, ensuring unobstructed liquid supply. Table 2 below shows the corresponding status of some valves, pumps, and other components on the test equipment during the first start-up test.

[0076] Table 2 First Startup Test

[0077] part Component corresponding status The first valve at inlet 111a Open The second valve at outlet 112b Open First electric valve 53 Open Second electric valve 56 Close / Open Liquid supply pump 55 closure Return pump 52 closure Drain valve 6 closure

[0078] Furthermore, by detecting the amount of liquid injected into the liquid cooling tank 1 using at least one of the liquid level sensor and the first flow sensor 1132a installed in the liquid cooling tank 1, it is determined that after the liquid injection into the liquid cooling tank 1 is completed, the corresponding states of some valves, pumps, and other components on the test equipment shown in Table 2 above change to the states shown in Table 3:

[0079] Table 3. Liquid cooling system completes liquid filling of the liquid cooling tank.

[0080] part Component corresponding status The first valve at inlet 111a Open The second valve at outlet 112b Open First electric valve 53 closure Second electric valve 56 Close / Open Liquid supply pump 55 closure Return pump 52 closure Drain valve 6 closure

[0081] The aforementioned closure of the first electric valve 53 prevents the liquid from evaporating and flowing into the storage tank 4 during the subsequent normal testing process. It should be noted that after the liquid cooling tank 1 is filled with liquid, normal testing of the data center will begin. During normal testing, the real-time power, voltage, and current of the simulation device can be monitored to monitor the power supply parameters of the electrical control system of the data center under test at the target power level of the simulation device 2. The power supply will be automatically cut off when an abnormality is detected.

[0082] 5.2) Under normal testing conditions, after the data center test is completed at the target power level using the simulation device, the first electric valve 53 and the return pump 52, as shown in Table 3 above, are opened to recover the liquid in the liquid cooling tank 1 to the storage tank 4. Specifically, during the process of recovering the liquid in the liquid cooling tank 1 to the storage tank 4, the states of some valves, pumps, and other components on the test equipment shown in Table 3 above change to the states shown in Table 4 below:

[0083] Table 4.1 Test End

[0084] part Component corresponding status The first valve at inlet 111a closure The second valve at outlet 112b closure First electric valve 53 Open Second electric valve 56 closure Liquid supply pump 55 closure Return pump 52 Open Drain valve 6 closure

[0085] It should be noted that at the end of the test, the exhaust device 41 located on top of the liquid storage tank 4 will be closed to prevent liquid evaporation; and the aforementioned second electric valve is to prevent the liquid in the liquid storage tank 4 from flowing back to the liquid cooling tank 1.

[0086] Furthermore, after the liquid level sensors installed in the liquid cooling tank 1 and the storage tank 4 determine that all the liquid in the liquid cooling tank 1 has been recovered into the storage tank 4, the liquid recovery is complete. Correspondingly, the states of the valves and pumps shown in Table 4.1 above change to the states shown in Table 4.2 below:

[0087] Table 4.2 Liquid recovery completed in liquid cooling tank 1

[0088] part Component corresponding status The first valve at inlet 111a closure The second valve at outlet 112b closure First electric valve 53 closure Second electric valve 56 closure Liquid supply pump 55 closure Return pump 52 closure Drain valve 6 closure

[0089] 5.3) After completing one test through steps 5.1) and 5.2) above, switch the simulation device to the next target power test point. Since there is no liquid in the liquid cooling tank 1 at this time, the second electric valve 56 and the liquid supply pump 55 installed on the liquid supply pipeline 54 need to be opened to supply the liquid in the storage tank 4 to the liquid cooling tank 1 to replenish the liquid in the liquid cooling tank 1. Specifically, during the process of supplying the liquid in the storage tank 4 to the liquid cooling tank, the states of some valves, pumps, and other components on the test equipment shown in Table 4 above change to the states shown in Table 5 below:

[0090] Table 5. Initiating a new test for the next target power.

[0091] part Component corresponding status The first valve at inlet 111a closure The second valve at outlet 112b closure First electric valve 53 Open Second electric valve 56 Open Liquid supply pump 55 Open Return pump 52 closure Drain valve 6 closure

[0092] The reason for opening the first electric valve 53 can be found in the relevant content described in 5.1).

[0093] Furthermore, assuming this new test is the last target power test, after determining that the liquid cooling tank 1 has been replenished by detecting the amount of liquid added to the liquid cooling tank 1 by the liquid level sensor installed in the liquid cooling tank 1, the states of some valves, pumps, and other components on the test equipment shown in Table 5 above can be changed to the states shown in Table 6 below:

[0094] Table 6 shows the completion of liquid replenishment in liquid cooler 1 for initiating a new test.

[0095]

[0096]

[0097] It should be noted that the reason for opening the valves at the inlet 111a and outlet 112b in Table 6 above is that, considering that a small portion of the liquid may evaporate during the test, this may result in the liquid volume in the liquid cooling tank 1 not meeting the current test requirements even if all the liquid in the storage tank 1 is supplied to the liquid cooling tank 1. Therefore, the liquid cooling system of the data center can be controlled to continue supplying liquid to the liquid cooling tank 1 until the liquid volume in the liquid cooling tank 1 meets the current test requirements.

[0098] 5.4) Under normal testing conditions, after the new test is fully completed, the drain valve 6 on the discharge pipeline can be opened to recover the liquid in the liquid cooling tank 1 and the very small amount of residual liquid in the storage tank 1 to the data center's liquid storage system. Specifically, during the process of recovering the liquid to the storage system, the states of the various valves and pumps shown in Table 6 above can be changed to the states shown in Table 7 below:

[0099] Table 7 shows the completion of the entire test, with the liquid being recovered to the storage system.

[0100] part Component corresponding status The first valve at inlet 111a closure The second valve at outlet 112b closure First electric valve 53 closure Second electric valve 56 Close / Open Liquid supply pump 55 closure Return pump 52 closure Drain valve 6 Open

[0101] Besides the descriptions in 5.1) to 5.4) above, which pertain to the operational states of various valves and pumps on the test equipment under normal testing scenarios, the liquid cooling tank 1 may also experience pressure loss or overpressure during actual testing. To address this issue, the liquid storage tank 4 in the test equipment provided in this embodiment also functions as a pressure regulating device to resolve pressure loss or overpressure problems in the liquid cooling tank 1 during testing. Specifically,

[0102] 5.5) When the liquid cooler 1 is depressurized and the storage tank 4 pressurizes the liquid cooler 1, the corresponding operating states of various valves and pumps on the test equipment are shown in Table 8.1 below:

[0103] Table 8.1 Pressurization of Liquid Storage Tank 4 to Liquid Cooling Box 1

[0104]

[0105]

[0106] 5.6) When the liquid storage tank 4 depressurizes the liquid cooling tank 1 under overpressure conditions, the corresponding operating states of various valves and pumps on the test equipment are shown in Table 8.2 below:

[0107] Table 8.1 Pressure relief of liquid storage tank 4 and liquid cooling tank 1

[0108] part Component corresponding status The first valve at inlet 111a Open (Close in case of severe overpressure) The second valve at outlet 112b Open (Close in case of severe overpressure) First electric valve 53 Open Liquid supply pump 55 closure Return pump 52 Open Drain valve 6 closure

[0109] It should be noted that during the test process described in 5) above, the control device 3 can monitor the test status in real time and take corresponding actions according to the set time and other requirements. For example, if an abnormality occurs (such as excessively high liquid temperature), an alarm will be triggered and the power supply will be cut off. In other cases, if the heating resistors of the simulation device 2 experience derating, power compensation will be automatically performed according to the set power parameters, stopping once the specified power is replenished. Furthermore, the liquid storage tank 4 can also be used to stabilize the pressure balance of the data center's liquid storage system during the test, preventing pressure loss or overpressure. For details on the specific implementation of stabilizing the pressure balance of the liquid storage system, please refer to the descriptions in 5.5) to 5.6) above regarding the actions of the controlled valves and / or pumps in the event of pressure loss or overpressure in the liquid cooling tank 1.

[0110] Furthermore, such as Figure 5a As shown, the data center testing equipment provided in this application embodiment may further include a filtration device 20. The filtration device 20 may be installed at the inlet pipe 111 and / or the outlet pipe 112, and is used to start working to filter the circulating liquid when the testing equipment is not performing a testing task.

[0111] See Figure 5a In the example shown, a bypass pipe is provided on the outlet pipe 112, and the filter device 20 is installed on the bypass pipe. The outlet pipe and the bypass pipe are connected. The outlet pipe 112 has two connecting ends, which are respectively connected to the two connecting ends of the bypass pipe. A switch valve 203 can be installed between the two connecting ends of the outlet pipe 112; a bypass valve 201 is provided on the bypass pipe. The filter device 20 includes: the bypass valve 201 and the filter 202.

[0112] In actual operation, there are two modes:

[0113] (1) Test mode: In this mode, the bypass valve 201 on the bypass pipeline is closed, and the switch valve on the outlet pipeline 112 is open. The filter 202 is not activated, the heating resistor in the liquid cooling box is working, and the system performs the test.

[0114] (2) Filtration mode: At this time, the bypass valve 201 on the bypass pipeline is open, the switch valve on the outlet pipeline 112 is closed, the filter 202 is activated, the heating resistor in the liquid cooling box is not working, and the system only performs liquid circulation and filtration.

[0115] In practice, the filtering mode is usually performed first, such as a preset duration (e.g., 10-50 minutes, or 30 minutes), before switching to the test mode for testing.

[0116] After the test, the system switches back to filtration mode for a preset duration, then the liquid is returned to the storage tank, ending the test. The circulating liquid may be contaminated, such as by impurities from equipment within the liquid cooling tank. Adding a filtration device can filter the circulating liquid in the liquid cooling tank to remove impurities, thus improving the testing accuracy of the equipment.

[0117] like Figure 5a The example shown is more Figure 1b The number of water outlets and inlets has increased, but the water outlet and inlet pipes remain unchanged. For example... Figure 5b Another implementation of the test equipment of this application is shown, namely, multiple return lines 51 can be set, such as the two shown in the figure, to improve the return efficiency. Of course, multiple supply lines can also be set to increase the supply efficiency.

[0118] In summary, the data center testing equipment provided in this embodiment has the following beneficial effects:

[0119] 1. By utilizing the liquid storage tank and intelligent control system (such as control device and liquid storage control device), the liquid in the testing device is recycled and reused, avoiding problems such as liquid waste and environmental pollution.

[0120] 2. The operating power of the simulation device within the testing equipment is adjustable, currently supporting a maximum power adjustment of 360KW. This enables full-load testing of data center liquid cooling systems. Furthermore, the modular simulation device allows for flexible replacement and disassembly, making it easily adaptable to various types of liquid cooling systems. Additionally, during testing, when the simulation device's power fluctuates or decreases, automatic power compensation can be achieved to match the testing requirements.

[0121] 3. Automatic monitoring of test data (liquid temperature, liquid flow rate, etc.). Utilizing various intelligent sensors integrated into the testing equipment, key parameters such as the inlet and outlet water temperature and flow rate of the data center's liquid cooling system can be automatically detected during the testing process. The actual cooling capacity can then be calculated, making it simpler and more intelligent compared to traditional offline data recording and calculation. Furthermore, through automatic monitoring of liquid temperature and flow rate, various functions such as real-time data display, dynamic alarms, and threshold protection are also implemented. Because existing testing equipment lacks various alarm functions, it is often prone to accidents such as fires. However, the technical solution provided in this embodiment, through threshold settings and upper limit reminders, ensures safe use. Moreover, in actual testing, if a problem occurs, the power can be cut off and an alarm can be issued at any time, effectively protecting personal safety.

[0122] 4. Automatic pressure stabilization and liquid level control. While realizing the recycling of liquid, the liquid storage tank can automatically adjust the overpressure and underpressure of the liquid storage system in the liquid cooling box and data center to ensure the stability of the system, and also realize the control functions of high and low liquid levels.

[0123] Figure 6 A flowchart illustrating a data center testing method according to an embodiment of this application is shown. The execution entity of this method is as follows: Figure 1b The test equipment shown includes a control device 3. In addition, the test equipment may also include a liquid cooling tank 1, a simulation device 2 located within the liquid cooling tank 1, and a liquid storage tank 4. For a detailed description of the test equipment, its specific components, and the functions of each component, please refer to the relevant content in the embodiments above. As shown in Figure 5, the method includes the following steps:

[0124] 101. In response to the user-triggered test start command, obtain the target power;

[0125] 102. Send a test command to the electrical control system of the data center under test to make the liquid cooling system of the data center under test work to supply liquid to the liquid cooling tank of the test equipment and promote the circulation of liquid in the liquid cooling tank;

[0126] 103. Control the simulation device inside the liquid cooling box to simulate the target power;

[0127] 104. Monitor the power supply parameters of the electrical control system of the data center under test at the target power, as well as the cooling parameters of the liquid cooling system during operation.

[0128] For a detailed description of 101 to 103 above, please refer to the relevant content of the above embodiments.

[0129] In the above 104, the power supply parameters can be determined by monitoring the voltage, current, etc., generated by the simulation device operating at the target power. The refrigeration parameters during the operation of the liquid cooling system are parameters that can standardize the refrigeration effect of the liquid cooling system. In some embodiments, the refrigeration parameters can be determined by monitoring the temperature of the liquid flowing from the liquid cooling system into the liquid cooling tank and the temperature of the liquid recovered from the liquid cooling tank into the liquid cooling system. The temperatures of the liquid flowing into the liquid cooling tank and the liquid recovered into the liquid cooling system can be detected by temperature sensors installed in the testing equipment. For details on the specific location of the temperature sensors, please refer to the relevant content above. Specifically, but not limited to, the difference between the temperature of the liquid recovered from the liquid cooling tank into the liquid cooling system and the temperature of the liquid flowing from the liquid cooling system into the liquid cooling tank can be directly used as the refrigeration parameters of the liquid cooling system.

[0130] Furthermore, the method provided in this embodiment also includes:

[0131] 105. In response to a user-triggered test end command, control the liquid storage control device to operate, so as to recover the liquid in the liquid cooling tank into the liquid storage tank;

[0132] 106. In response to a user-triggered command to restart the test, control the liquid storage control device to operate, so as to supply the liquid in the liquid storage tank to the liquid cooling tank, so that the liquid volume in the liquid cooling tank meets the test requirements.
