Thus, the user can voluntarily choose whether to provide the personal information to the software or hardware such as the electronic device, the application program, the server or the storage medium, etc. performing the operation of the technical solutions of the present disclosure according to the prompt information.

[0019] It can be understood that the above notification and obtaining of the authorization of the user are only illustrative, and do not limit the implementation manners of the present disclosure, and other manners meeting the relevant laws and regulations can also be applied to the implementation manners of the present disclosure.

[0020] At the same time, it can be understood that the data (including but not limited to the data itself, the acquisition or use of the data) involved in the present technical solution should comply with the requirements of the corresponding laws and regulations and relevant provisions.

[0021] With the rapid development of cloud computing and other technologies, the computing power demand corresponding thereto is continuously improved, so that the power density of the data center is higher and higher, resulting in that the heat production of the cabinet is larger and larger, and a single air cooling heat dissipation technology is difficult to meet the heat dissipation demand of high-density heat load. The cold plate liquid cooling heat dissipation technology and application are becoming mature and are applied on a large scale.

[0022] The cold plate liquid cooling heat dissipation technology is a wind-liquid mixed heat dissipation technology. For example, the rated power consumption of the entire cabinet is 20 kilowatts, of which 30% or 50% of the heat load is responsible for heat dissipation by the air cooling equipment in the machine room, and the remaining load is taken away by the cooling liquid flowing in the cold plate arranged under the server mainboard in the cabinet. At the same time, due to the diversity of business demand and the compatibility demand of the machine room, there are usually both liquid cooling and air cooling heat dissipation systems in the machine room of the data center.

[0023] In the related art, the air-cooled part is usually tested by an air-cooled dummy load first, and then the liquid-cooled part is tested by a liquid-cooled dummy load. The test efficiency is low and the power consumption is high in the process, which is easy to cause resource waste. More importantly, in the actual operation process of the data center, the air-cooled system and the liquid-cooled system work together and influence each other, and the single test is easy to deviate. In addition, the air-cooled dummy load does not have the air volume adjustment function, and cannot effectively verify whether there is a local hot spot or air flow organization abnormality in the computer room. In addition, the server dummy load in the related art is not applicable to the application scene of the data center including multiple cabinets.

[0024] Therefore, the present disclosure provides a heat dissipation test method and system for a server cabinet to solve the above technical problems.

[0025] The embodiments of the present disclosure are further explained and described below with reference to the accompanying drawings.

[0026] Figure 1 is a flow chart of a heat dissipation test method for a server cabinet according to an exemplary embodiment of the present disclosure, referring to Figure 1 The heat dissipation test method comprises the following steps: S101: In response to the control operation of the dummy load module of the heat dissipation test system, the dummy load module is controlled to operate according to the control instruction corresponding to the control operation.

[0027] The dummy load module is integrated in the frame of the heat dissipation test system by a detachable connection mode, the dummy load module includes a plurality of liquid-cooled dummy loads and a plurality of air-cooled dummy loads, and the heat dissipation test system is used to simulate the heat dissipation working condition of the server cabinet to perform heat dissipation test.

[0028] In the embodiments of the present disclosure, the heat dissipation test system can be understood as a modularized air-liquid system compatible test simulation device, that is, the air-cooled dummy load and the liquid-cooled dummy load are separately detachable modularized devices, and then integrated in the frame by a detachable connection mode to form a simulation device in the form of a whole cabinet. The detachable connection mode can mean that the dummy load module is integrated in the frame through a pluggable interface, etc., which is not limited in the present disclosure.

[0029] In this way, the modules of the heat dissipation test system and the frame can be disassembled and transported to a designated location, and then a test environment can be quickly built up by module assembly. Specifically, the test environment can be built according to the actual computer room, so as to simulate the actual operation and heating of the server cabinet in the actual use scene. Not only can it be configured on demand, but also it is flexible to disassemble and assemble, and convenient to transport.

[0030] S102: Obtain the running data of the dummy load module, and the running data is used to determine the test result of the heat dissipation test system.

[0031] By using the above method, the heat dissipation test system can simulate the heat dissipation working condition of the server cabinet for heat dissipation test, is suitable for the application scene of the data center including multiple cabinets, and the dummy load module includes multiple liquid cooling dummy loads and multiple air cooling dummy loads, supports simultaneous heat dissipation test of the air cooling system and the liquid cooling system, improves the test efficiency, and reduces resource waste. In addition, the dummy load module is integrated in the machine frame of the heat dissipation test system through a detachable connection mode, which not only can be configured as needed, but also is flexible to disassemble and assemble, and is convenient for transportation.

[0032] In the embodiments of the present disclosure, the heat dissipation test system can include a liquid cooling dummy load module, an air cooling dummy load module, a dummy load connecting piece, a machine frame, a data acquisition module and a data transmission module, and can also include an operation processing module for local control and / or a remote terminal for remote control. The operation processing module for local control can be controlled by buttons, switches and other physical controls, or can be controlled by interface operation on the display screen based on the corresponding application program. Remote control mainly relies on the installation of the corresponding application program on the remote terminal, and the user can perform remote control by interface operation on the display screen of the remote terminal. The specific settings can be made according to the requirements, and the present disclosure does not limit this.

[0033] In the embodiments of the present disclosure, the air cooling dummy load can include a fan, an air resistance regulator, a heat load submodule, a control submodule, and air speed, temperature, pressure, power and other acquisition devices. The specific settings can be made according to the requirements, and the present disclosure does not limit this. The fan generates air flow by rotating and discharges hot air. The heat load submodule can act according to the instructions of the control submodule, for example, the control submodule can increase or decrease the load according to the set instructions, or can accept instructions from other control ends. The specific settings can be made according to the requirements, and the present disclosure does not limit this. The heat source of the heat load submodule is composed of an electric heating wire that can withstand high temperature for a long time. The actual required load size of the heat load submodule with a calibrated capacity is determined by the length of the total resistance wire connected in the load loop. The length of the connected resistance wire is controlled and adjusted by the control submodule.

[0034] In addition, the air resistance regulator is used to adjust the effective cross-sectional area of the air inlet of the air cooling dummy load, to simulate the difference in air inlet size under different working conditions and different server loads. The air speed sensor arranged at the air inlet is used to collect the air speed of the air inlet. The temperature sensor arranged at the air inlet is used to collect the air temperature of the air inlet. The temperature sensor arranged at the air outlet of the air cooling dummy load is used to collect the air temperature of the air outlet. The power sensor is used to collect the heat power of the heat load submodule. The pressure sensor arranged at the air inlet is used to collect the air pressure of the air inlet. The pressure sensor arranged at the air outlet is used to collect the air pressure of the air outlet.

[0035] In the embodiments of the present disclosure, the liquid cooling dummy load can include a flow resistance regulator, a thermal load submodule, a control submodule, and a flow rate, temperature, pressure, power, and the like acquisition device, which can be set according to requirements, and the present disclosure does not limit this. The thermal load submodule of the liquid cooling dummy load is similar to the thermal load submodule of the air cooling dummy load, and the present disclosure does not repeat it. The flow resistance regulator is used to adjust the effective cross-sectional area of the liquid inlet of the liquid cooling dummy load, to simulate the flow rate difference of the cooling liquid under different working conditions and different server loads. The flow rate sensor arranged at the liquid inlet is used to acquire the flow rate of the liquid inlet, the temperature sensor arranged at the liquid inlet is used to acquire the water temperature of the liquid inlet, the temperature sensor arranged at the liquid outlet of the liquid cooling dummy load is used to acquire the water temperature of the liquid outlet, the power sensor is used to acquire the heat power of the thermal load submodule, the pressure sensor arranged at the liquid inlet is used to acquire the water pressure of the liquid inlet, and the pressure sensor arranged at the liquid outlet is used to acquire the water pressure of the liquid outlet.

[0036] The above-mentioned air cooling dummy load and liquid cooling dummy load can be configured according to actual scenes and requirements, for example, some sensors can be added or reduced according to test requirements, and the like, and the present disclosure does not limit this.

[0037] Before the test, the air cooling dummy load and the liquid cooling dummy load can be deployed in the machine frame according to the proportion of the air cooling and liquid cooling load of the cold plate liquid cooling system as needed, to form a mixed dummy load meeting the test requirements. The liquid cooling dummy load is connected to the cooling structure of the liquid cooling system through a connecting piece. During the test execution, the load of each dummy load module, the acquired information, and the like can be transmitted to the above-mentioned operation processing module or remote terminal through the data transmission module, for data recording and analysis, and the present disclosure does not limit this.

[0038] In a possible manner, the control instruction includes a first instruction for the thermal load submodule of the dummy load module and a second instruction for the adjustment submodule of the dummy load module, and the adjustment submodule includes the flow resistance regulator of the liquid cooling dummy load and the air resistance regulator of the air cooling dummy load. According to the control operation corresponding to the control instruction, the dummy load module is controlled to run, including: adjusting the length of the resistance wire in the thermal load submodule according to the set load change amount corresponding to the first instruction, until the difference between the actual load change amount corresponding to the power of the thermal load submodule and the set load change amount is less than or equal to a fourth preset difference; controlling the valve opening degree of the flow resistance regulator according to the first setting parameter for the flow resistance regulator in the second instruction, so that the actual working condition of the liquid cooling dummy load reaches the preset working condition corresponding to the first setting parameter, and controlling the valve opening degree of the air resistance regulator according to the second setting parameter for the air resistance regulator in the second instruction, so that the actual working condition of the air cooling dummy load reaches the preset working condition corresponding to the second setting parameter.

[0039] For example, as shown in FIG. 6, the control instruction includes a first instruction for the thermal load submodule of the dummy load module and a second instruction for the adjustment submodule of the dummy load module, and the adjustment submodule includes the flow resistance regulator of the liquid cooling dummy load and the air resistance regulator of the air cooling dummy load. Figure 2As shown, taking the setting of the air-cooled dummy load as an example, the data transmission module can receive the control instruction and forward the control instruction to the control submodule, and the control submodule can adjust the length of the resistance wire in the thermal load submodule according to the set load change amount carried in the control instruction. The actual load change amount of the thermal load submodule can be determined according to the power collected by the power sensor, and the set load change amount can be an increase in load or a decrease in load, which is not limited in the present disclosure. Further, it is judged whether the deviation between the actual load change amount and the set load change amount meets the preset deviation, that is, the difference between the two is less than or equal to the fourth preset difference, so that it can be determined that the load loading is completed. The fourth preset difference can be set according to requirements, which is not limited in the present disclosure.

[0040] The load setting of the liquid-cooled dummy load can refer to the above process, which is not limited in the present disclosure.

[0041] For example, continuing to refer to Figure 2 Taking the setting of the air-cooled dummy load as an example, according to the second setting parameter for the air resistance regulator in the second instruction, for example, it can be an air resistance parameter, a wind speed parameter, etc., and the valve opening degree of the air resistance regulator is controlled according to the second setting parameter, so that the actual air resistance of the air resistance regulator reaches the air resistance configured by the air resistance parameter, or the actual wind speed of the air inlet reaches the wind speed configured by the wind speed parameter, etc. The specific configuration can be configured according to requirements, which is not limited in the present disclosure.

[0042] Correspondingly, for the liquid-cooled dummy load, according to the first setting parameter for the flow resistance regulator in the second instruction, for example, it can be a flow resistance parameter, a flow speed parameter, etc., and the valve opening degree of the flow resistance regulator is controlled according to the first setting parameter, so that the actual flow resistance of the flow resistance regulator reaches the flow resistance configured by the flow resistance parameter, or the actual flow speed of the liquid inlet reaches the flow speed configured by the flow speed parameter, etc. The specific configuration can be configured according to requirements, which is not limited in the present disclosure.

[0043] It should be noted that the adjustment of the thermal load submodule and the adjustment of the air resistance regulator can be synchronous or asynchronous. The control submodule of the liquid-cooled dummy load is responsible for processing the control instruction related to the liquid-cooled dummy load, and the control submodule of the air-cooled dummy load is responsible for processing the control instruction related to the air-cooled dummy load. That is, the control instruction corresponding to the first setting parameter and the control instruction corresponding to the second setting parameter can be different control instructions, or when the user performs a control operation, a control instruction for a certain dummy load module is generated after the configuration of the dummy load module is completed, etc. The present disclosure is not limited in this regard.

[0044] By configuring different liquid-cooled dummy loads and air-cooled dummy loads on demand to form a mixed dummy load that meets the test requirements, different working conditions of the server cabinet can be simulated according to the configuration, different test requirements can be met, and the test flexibility is improved.

[0045] In a possible manner, in response to the control operation on the dummy load module of the heat dissipation test system, the dummy load module is controlled to run according to the control instruction corresponding to the control operation. The heat dissipation test method further includes: sending the running data to the remote terminal, so that the remote terminal determines the test result of the heat dissipation test system according to the running data.

[0046] For example, the remote terminal can be a terminal device such as a computer, a mobile phone, a tablet, etc. An application program for controlling the heat dissipation test system can be run on the remote terminal. On the operation page of the application program, a user can perform a control operation according to a requirement, for example, the parameter configuration of the heat load submodule and the adjustment submodule described above, etc. The specific configuration can be set according to a requirement, and the present disclosure does not limit this.

[0047] Further, the remote terminal generates a corresponding control instruction according to a user operation and sends the control instruction to the data transmission module of the heat dissipation test system, which is forwarded to the corresponding dummy load module by the data transmission module. Of course, the adjustment can also be performed at any time during the test. Thus, the online control of the heat dissipation test system can be realized, and the test flexibility and efficiency are improved.

[0048] For example, during the test execution, the running data, for example, the power, the wind speed, etc., collected by each dummy load module can be transmitted to the remote terminal through the data transmission module. The remote terminal records and analyzes the running data to obtain the final test result, and can also generate a corresponding test report, etc. The specific configuration can be set according to a requirement, and the present disclosure does not limit this. Thus, the online control, online analysis and online summary of the heat dissipation test system can be realized, and the test efficiency is improved.

[0049] In a possible manner, the running data of the dummy load module is obtained, including: for each air-cooled dummy load in the plurality of air-cooled dummy loads, obtaining the first wind speed and the first temperature corresponding to the air inlet of the air-cooled dummy load, the second temperature corresponding to the air outlet of the air-cooled dummy load, and the first effective cross-sectional area of the air inlet fed back by the air resistance regulator of the air-cooled dummy load. The heat dissipation test method further includes: for each air-cooled dummy load in the plurality of air-cooled dummy loads, obtaining the first air inlet amount according to the product of the first wind speed and the first effective cross-sectional area, and obtaining the heat load corresponding to the air-cooled dummy load according to the product of the temperature difference between the first temperature and the second temperature and the first air inlet amount; and determining the test result representing whether there is a local hot spot in the heat dissipation test system according to the heat loads corresponding to the plurality of air-cooled dummy loads.

[0050] For example, the heat dissipation test system further comprises a data acquisition module. For each air-cooled dummy load, the data acquisition module is used to acquire the first effective cross-sectional area of the air inlet fed back by the air resistance regulator, the first air speed corresponding to the air inlet acquired by the air speed sensor arranged at the air inlet, the first temperature of the air inlet acquired by the temperature sensor arranged at the air inlet, and the second temperature of the air outlet acquired by the temperature sensor arranged at the air outlet. Then, the data acquired by the data acquisition module is transmitted to the local operation processing module or the remote terminal through the data transmission module for data analysis and processing.

[0051] Further, the operation processing module or the remote terminal can perform data analysis and processing on the received data, for example, to perform simulation analysis on the local hot spots of the cabinet server. For each air-cooled dummy load, the first air inlet amount of the air inlet can be obtained according to the product of the first effective cross-sectional area and the first air speed, and then the thermal load corresponding to the air-cooled dummy load can be obtained according to the product of the temperature difference between the first temperature and the second temperature and the first air inlet amount, so as to subsequently judge whether there is a local hot spot in the heat dissipation test system. Through automatic data acquisition and automatic analysis and processing, the simulation analysis on the local hot spots of the cabinet server is completed, and the test efficiency is improved.

[0052] In a possible manner, the test result representing whether there is a local hot spot in the heat dissipation test system is determined according to the thermal loads corresponding to the plurality of air-cooled dummy loads, including: determining an average thermal load according to the thermal loads corresponding to the plurality of air-cooled dummy loads; in the case that there is a first air-cooled dummy load in the plurality of air-cooled dummy loads, the difference between the thermal load corresponding to the first air-cooled dummy load and the average thermal load is greater than a first preset difference value, determining the test result representing that there is a local hot spot in the region corresponding to the first air-cooled dummy load in the heat dissipation test system; or in the case that there is a second air-cooled dummy load in the plurality of air-cooled dummy loads, the ratio between the thermal load corresponding to the second air-cooled dummy load and the average thermal load is greater than a preset ratio, determining the test result representing that there is a local hot spot in the region corresponding to the second air-cooled dummy load in the heat dissipation test system.

[0053] For example, in the process of judging whether there is a local hot spot in the heat dissipation test system, the average thermal load of the plurality of thermal loads corresponding to the plurality of air-cooled dummy loads can be calculated, and then the difference between the thermal load corresponding to each air-cooled dummy load and the average thermal load is compared. If there is a first air-cooled dummy load with a difference greater than a first preset difference value, it means that the thermal load of the region corresponding to the first air-cooled dummy load is higher than that of other regions, and then it can be determined that there is a local hot spot in the region corresponding to the first air-cooled dummy load. Alternatively, the ratio between the thermal load corresponding to each air-cooled dummy load and the average thermal load can also be calculated. If there is a second air-cooled dummy load with a ratio greater than a preset ratio, it means that the thermal load of the region corresponding to the second air-cooled dummy load is higher than that of other regions, and then it can be determined that there is a local hot spot in the region corresponding to the second air-cooled dummy load.

[0054] For example, if it is determined that there is a local hot spot in the machine room, the heat dissipation of the machine room can be checked. For example, if the local hot spot is caused by uneven heat dissipation in this area of the machine room, the heat dissipation strategy of this area can be adjusted according to the test results. The specific adjustment can be set according to the requirements, and the present disclosure does not limit the adjustment. The first preset difference and the preset ratio can be set according to the requirements, and the present disclosure does not limit the adjustment. Through automatic collection and automatic analysis of data, simulation analysis of local hot spots of the cabinet server is completed, and the test efficiency is improved.

[0055] In a possible manner, the operation data of the dummy load module is obtained, including: for each air-cooled dummy load in the plurality of air-cooled dummy loads, obtaining a second air speed corresponding to an air inlet of the air-cooled dummy load and a third temperature, and a second effective cross-sectional area of the air inlet fed back by the air resistance adjustment machine. The heat dissipation test method further includes: for each air-cooled dummy load in the plurality of air-cooled dummy loads, obtaining a second air inlet amount according to the product of the second air speed and the second effective cross-sectional area; and determining a test result representing whether the air flow organization of the heat dissipation test system is abnormal according to the respective second air inlet amounts and the respective third temperatures of the plurality of air-cooled dummy loads.

[0056] For example, as shown in Figure 3 For each air-cooled dummy load in the plurality of air-cooled dummy loads, the second air speed collected by the wind speed sensor arranged at the air inlet and the third temperature collected by the temperature sensor arranged at the air inlet are obtained by the data acquisition module, and the second effective cross-sectional area of the air inlet fed back by the air resistance adjustment machine is obtained. The data collected by the data acquisition module is sent to the local operation processing module or the remote terminal for data analysis and processing by the data transmission module.

[0057] Further, the operation processing module or the remote terminal can perform data analysis and processing on the received data, for example, simulation analysis of whether the air flow organization of the cabinet server is reasonable. For each air-cooled dummy load, the second air inlet amount of the air inlet can be obtained according to the product of the second effective cross-sectional area and the second air speed, and then whether the air flow organization of the heat dissipation test system is abnormal can be determined according to the respective second air inlet amounts and the respective third temperatures of the plurality of air-cooled dummy loads. Through automatic collection and automatic analysis of data, simulation analysis of whether the air flow organization of the cabinet server is reasonable is completed, and the test efficiency is improved.

[0058] In a possible implementation, the test result characterizing whether the airflow organization of the heat dissipation test system is abnormal is determined according to the second air inlet amount and the third temperature corresponding to each of the plurality of air-cooled dummy loads, including: determining an average air inlet amount according to the second air inlet amount corresponding to each of the plurality of air-cooled dummy loads, and determining an average temperature according to the third temperature corresponding to each of the plurality of air-cooled dummy loads; and in a case where there is a third air-cooled dummy load in the plurality of air-cooled dummy loads, a difference between the second air inlet amount corresponding to the third air-cooled dummy load and the average air inlet amount is greater than a second preset difference value and / or a difference between the third temperature corresponding to the third air-cooled dummy load and the average temperature is greater than a third preset difference value, the test result characterizing that the region corresponding to the third air-cooled dummy load in the heat dissipation test system has airflow organization abnormality is determined.

[0059] For example, continuing to refer to Figure 3 The consistency of the temperature and the air inlet amount of the air inlet of each air-cooled dummy load can be judged to determine whether the region corresponding to each air-cooled dummy load has airflow organization abnormality. For example, the average air inlet amount of the air inlets of the plurality of air-cooled dummy loads can be calculated first, and then the difference between the air inlet amount of the air inlet of each air-cooled dummy load and the average air inlet amount is compared. If there is an air-cooled dummy load with a difference greater than a second preset difference value, it can be determined that the region where the air-cooled dummy load is located has airflow organization abnormality, the region where the air-cooled dummy load is located can be checked and repaired, and the corresponding heat dissipation strategy can be adjusted, and the like, which are not limited in the present disclosure.
