Figure 2 This is a flowchart of a test method for a liquid cooling system according to Embodiment 1 of the present invention, as shown below. Figure 2 As shown, the method includes the following steps:

[0035] Step S202: If it is determined that the liquid cooling system meets the start-up conditions, start the test equipment according to the predetermined power. The test equipment is used to monitor the heat dissipation effect of the liquid cooling system in the computer room and the power safety of the circuit, and obtain the operating parameter values.

[0036] Step S204: Obtain the operating parameter values ​​monitored by the aforementioned test equipment;

[0037] Step S206: Determine whether the above operating parameter values ​​have reached the corresponding alarm threshold;

[0038] Step S208: If the above operating parameter values ​​reach the above alarm threshold, then output alarm indication information.

[0039] Optionally, the above-mentioned testing equipment is a liquid-cooled testing equipment, that is, a testing equipment that uses immersion cooling for heat dissipation; the above-mentioned operating parameter values ​​include at least one of the following: cooling water temperature, cooling water flow rate, pipeline pressure, load voltage, and load current.

[0040] Optionally, the above-mentioned start-up conditions may include, but are not limited to, the following: the above-mentioned cooling water inlet pipe and the above-mentioned cooling water outlet pipe are connected normally; the inlet valve, outlet valve and vent valve in the above-mentioned test equipment are all in the closed state; all the wiring in the above-mentioned liquid cooling system is correctly connected, etc.

[0041] Optionally, the predetermined power can be the maximum power of the test equipment. Before starting the test equipment, turn on the air switch corresponding to the maximum test equipment under the full load condition of the system required for the test, obtain the resistance value of the test equipment under the full load condition of the system required for the test, and set the predetermined test power through the human-machine interface.

[0042] In this embodiment of the invention, by starting the test equipment at a predetermined power when the liquid cooling system meets the start-up conditions, the test equipment is used to monitor the heat dissipation effect of the liquid cooling system in the computer room and the electrical safety of the circuit, and to obtain operating parameter values; to obtain the operating parameter values ​​monitored by the test equipment; to determine whether the operating parameter values ​​have reached the corresponding alarm threshold; and if the operating parameters have reached the alarm threshold, to output alarm indication information. This achieves the purpose of using liquid cooling to test the system, obtain and monitor the system operating parameters, thereby improving the heat dissipation efficiency of the test equipment, ensuring the stability of the system test, and improving the electrical safety of the equipment. This solves the technical problems of low heat dissipation efficiency and poor test stability in the existing liquid cooling system test methods.

[0043] In one optional embodiment, after determining that the liquid cooling system meets the start-up conditions, the test equipment is started at a predetermined power. The test equipment is slowly heated up, and the cooling water begins to dissipate heat from the test equipment. During the system test, the test equipment automatically acquires the operating parameter values ​​(such as cooling water temperature, cooling water flow rate, pipeline pressure, load voltage, and load current) according to the preset test time and test requirements (such as power factor, current value, etc.), and performs real-time detection on the operating parameter values. When the detected operating parameters reach the alarm threshold, an alarm indication message is issued.

[0044] Optionally, before starting the above-mentioned testing equipment, the alarm threshold corresponding to each operating parameter can be set through the human-machine interface, such as the range of cooling water temperature, the range of cooling water flow, the range of pipeline pressure, the range of load voltage, and the range of load current, etc.

[0045] Optionally, after obtaining the above operating parameters, the current value and changes of each operating parameter can be displayed in real time on the human-machine interface using performance curves.

[0046] Optionally, the testing equipment is connected to the liquid cooling system via a water pipeline, wherein the water pipeline includes at least one cooling water inlet pipeline and at least one cooling water outlet pipeline, and the number of cooling water inlet pipelines and cooling water outlet pipelines is the same. For example, Figure 3This is a schematic diagram of the internal structure of an optional testing device according to an embodiment of the present invention. Figure 3 The test equipment shown has a cooling water inlet pipe and a cooling water outlet pipe. Low-temperature cooling water flows into the test equipment from the cooling water inlet pipe. After flowing through each thermal resistor, the cooling water temperature rises, and high-temperature cooling water flows out of the test equipment from the cooling water inlet pipe.

[0047] In an optional embodiment, before starting the test equipment at a predetermined power, the method further includes:

[0048] The cooling water inlet pipe and the cooling water outlet pipe are connected by flexible connections and vibration damping interfaces.

[0049] After confirming that the cooling water inlet pipe and the cooling water outlet pipe are connected normally, liquid is injected into the test equipment through the cooling water inlet pipe until the test equipment is full of liquid.

[0050] Optionally, the aforementioned flexible connection is a pipe fitting made of flexible material, used to compensate for disturbances caused by vibrations from the aforementioned testing equipment.

[0051] Optionally, the cooling water inlet pipe and the cooling water outlet pipe are connected using flexible connections and shock-absorbing interfaces. After confirming that the cooling water inlet pipe and the cooling water outlet pipe are properly connected, that is, ensuring that the cooling water inlet pipe and the cooling water outlet pipe are tightly connected and leak-free, the vent valve is opened to release the air, and liquid is injected into the test equipment through the cooling water inlet pipe until the test equipment is full of liquid.

[0052] Optionally, the liquid mentioned above may be, but is not limited to, pure water, softened water, etc. When a small amount of the liquid is observed to be discharged, it means that the test equipment has been vented and the interior is filled with the liquid.

[0053] In one optional embodiment, during the process of injecting liquid into the test equipment through the cooling water inlet pipe, the internal pressure value of the test equipment is adjusted in real time by a static pressure regulating valve until the test equipment is filled with the liquid.

[0054] It should be noted that during the process of injecting cooling water into the above-mentioned testing equipment, an imbalance in the internal pressure of the testing equipment may occur. By setting the above-mentioned static pressure regulating valve, the internal pressure value of the testing equipment can be adjusted in real time to ensure the internal pressure balance of the testing equipment.

[0055] In an optional embodiment, after starting the test equipment at a predetermined power, the method further includes:

[0056] Check whether the resistance temperature detectors in the above-mentioned testing equipment have undergone derating.

[0057] If the aforementioned thermal resistor exhibits the aforementioned derating, then the power compensation of the aforementioned test equipment shall be performed according to the aforementioned predetermined power until the aforementioned test equipment reaches the target load power.

[0058] Optionally, the derating condition described above is used to indicate that the current resistance value of the aforementioned thermal resistor is less than the target resistance value.

[0059] Optionally, if the thermal resistor experiences a derating during the testing of the liquid cooling system, i.e., the current resistance value of the thermal resistor is less than the target resistance value, then the power compensation of the tested thermal resistor is automatically performed according to the predetermined power until the thermal resistor reaches the target load power.

[0060] As an optional embodiment, Figure 4 This is a flowchart of an optional test method for a liquid cooling system according to an embodiment of the present invention, such as... Figure 4 As shown, the above method also includes:

[0061] Step S402: After the test of the above liquid cooling system is completed, the test equipment is turned off.

[0062] Step S404: Control the opening of the exhaust valve and drain valve in the above-mentioned test equipment to discharge the liquid in the above-mentioned test equipment;

[0063] Step S406: Disconnect the water pipe connecting the test equipment and the liquid cooling system.

[0064] Optionally, after testing the liquid cooling system, shut down the test equipment. First, open the vent valve in the test equipment to vent air, then open the drain valve to drain the cooling water from the test equipment to a floor drain in the room or outside, until the liquid in the test equipment is completely drained. After the liquid in the test equipment is drained, disconnect all electrical cables connected to the test equipment, and disconnect the water pipe flexible connections and other interfaces. The test is then complete.

[0065] As an optional embodiment, Figure 5 This is a schematic diagram of an optional test method for a liquid cooling system according to an embodiment of the present invention, as shown below. Figure 5As shown, the shock absorber includes an inlet shock absorber and an outlet shock absorber, which are connected to the inlet and outlet water pipes respectively, for connecting external flexible connections and protecting the test equipment. After the cooling water enters the test equipment through the inlet shock absorber, the temperature, flow rate, and pipe pressure of the cooling water in the test equipment are measured by the T sensor (temperature sensor), F sensor (flow sensor), and P sensor (pressure sensor), respectively. The pressure reducing valve is used to buffer the inlet pressure according to the pipe pressure value to avoid pressure imbalance inside the test equipment. The low-temperature cooling water is evenly distributed to 1-N RTD modules through the water distributor. The cooling water passing through the RTD modules begins to heat up. The high-temperature cooling water obtained after flowing through each RTD module is collected by the water collector. During this process, the internal pressure value of the test equipment is adjusted in real time by the static pressure regulating valve until the test equipment is full of cooling water. After the test, the vent valve and drain valve are opened to discharge the liquid in the test equipment.

[0066] It should be noted that the testing equipment in this embodiment of the invention adopts an immersion cooling method, which can be directly connected to a liquid cooling system, making it convenient and reliable to use. It also employs a modular RTD design; when a single module RTD experiences high temperature or malfunction, it will automatically switch to a new load and issue an alarm in a timely manner, facilitating fault repair and load replacement. If a resistance value decreases, the system will automatically monitor and replenish it, ensuring test accuracy and stability. Multiple threshold protections are set for the testing equipment, including pressure protection, water temperature protection, resistance temperature protection, flow protection, liquid level protection, and leakage protection, effectively protecting the equipment and the safety of users. It can achieve intelligent monitoring of temperature, pressure, and flow, dynamically replenishing, adjusting, and protecting the operating testing equipment, effectively ensuring test stability.

[0067] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, because according to the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.

[0068] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a computer-readable storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods described in the various embodiments of the present invention.

[0077] Optionally, after obtaining the above operating parameters, the current value and changes of each operating parameter can be displayed in real time on the human-machine interface using performance curves.

[0078] In this embodiment of the invention, the test device 602 is connected to the liquid cooling system 600. When the liquid cooling system meets the startup conditions, the device starts the system at a predetermined power and detects the operating parameter values. The main control device 604 is connected to the test device 602 and determines whether the operating parameter values ​​reach the corresponding alarm threshold. When the operating parameter values ​​reach the alarm threshold, an alarm indication is output. This achieves the purpose of using liquid cooling for system testing, obtaining and monitoring system operating parameters, thereby improving the heat dissipation efficiency of the test device, ensuring system testing stability, and enhancing the electrical safety of the equipment. This solves the technical problems of low heat dissipation efficiency and poor testing stability in existing liquid cooling system testing methods.
