Description
Technical Field
The invention relates to the field of liquid cooling data center verification test tools, in particular to liquid cooling data center test equipment and a liquid cooling data center test system.
Background
With the development of technologies such as internet, cloud computing, artificial intelligence and the like, the construction scale of a data center is larger and larger, the Power consumption is more and more, the Power consumption accounts for 1% to 3% of the total annual Power consumption in the whole country, the Power consumption of the data center is increased by 20% after the data center is brought into high-energy consumption industry by the country, the Power Usage Efficiency (PUE) of the data center is newly built and built in succession by the country and various parts, the low PUE indicates that the energy consumption of the data center is low, otherwise, the energy consumption is high), the original data center adopting an air cooling server is difficult to realize the requirement of low PUE, and therefore more and more data centers adopt the form of a liquid cooling server.
After the data center is built, verification tests are usually needed, the verification tests are a deep check on the design and the construction of systems such as heating ventilation and power supply of the data center, various faults and problems of the systems in the design and construction process are found through various tests of the systems, and loss caused by system faults after the data center is put into operation is avoided. If verification tests are not carried out, unpredictable risks are brought to the operation of the data center in the later period.
In the related art, the data center adopting the air cooling server adopts the dummy load to test each function of each system during testing, the dummy load converts electric energy into heat energy during the testing process and releases the heat energy into a machine room environment, and the heat dissipated into the environment is finally dissipated outdoors by the machine room air conditioning system. The liquid-cooled data center is a data center that cools IT devices such as servers and the like by using cooling liquid, specifically, the servers of the liquid-cooled data center are "soaked" in a cabinet filled with cooling liquid, and are cooled by the cooling liquid supplied by a cooling liquid supply system, that is, a cooling liquid Distribution unit (CDU), and the heat absorbed by the cooling liquid cannot be dissipated through the environment of a machine room, so that dummy loads need to be soaked in the cooling liquid when the liquid-cooled data center is tested. If the method is adopted for testing, the cooling liquid is polluted, the later use is influenced, and the server is damaged in severe cases. Therefore, most of the currently-built liquid-cooling data centers do not test or utilize the formally-used liquid-cooling servers to test the CDU cooling and formally-used liquid-cooling servers, the test mode often does not meet the use requirements, and the servers are easily damaged in the test process.
Therefore, the data center adopting the liquid cooling server does not have suitable testing equipment at present, and the technical problem that the liquid cooling data center is inconvenient to test in the prior art is caused. In view of the above problems, no effective solution has been proposed.
The above information disclosed in the background section is only for enhancement of understanding of the background of the technology described herein. The background art may therefore contain certain information that does not form the known prior art to those skilled in the art.

Because the heating source 2 and the liquid cooling heat exchanger 3 are arranged in the closed installation cavity 100, heat emitted by the heating source 2 can be fully absorbed by cooling liquid in the heat exchanger 3, and the heated cooling liquid flows back to a cooling liquid supply system for cooling, so that heat balance in the installation cavity 100 is realized, and the heat is not diffused to a machine room environment to cause environmental heating to influence a test result. The cooling capacity of the cooling liquid supply system can be obtained by combining the heating power of the heating source 2, and whether the design of the cooling liquid supply system meets the cooling requirement is further checked. Moreover, when the test is carried out, the liquid cooling data center test equipment can simulate the liquid cooling cabinet in operation, and various tests can be conveniently carried out on the liquid cooling data center, so that various faults or defects existing in the design and construction process of the liquid cooling data center system can be found, the faults can be eliminated in time, and unnecessary loss caused by system faults after the liquid cooling data center is in delivery operation is avoided.

In actual implementation, the second direction may or may not coincide with the height direction. Specifically, the second direction is a direction perpendicular to the first direction, and therefore, there are innumerable choices for the second direction, such as a direction perpendicular to the paper surface, a direction coinciding with the height direction, and the like, but the height direction is unique, and is perpendicular not only to the first direction but also to the direction perpendicular to the paper surface.
