Spray Evaporative Cooling Supercomputer
Immersion Self-Circulating Evaporative Cooling Server
On January 13, a spray-type evaporative cooling supercomputer (QSC-1) developed by the Institute of Electrical Engineering of the Chinese Academy of Sciences for the Computer Network Information Center of the Chinese Academy of Sciences passed the Linpack test for 72 hours. This indicates that the spray evaporative cooling thermal management technology has been successfully and successfully demonstrated. It has transformed scientific research achievements into mature industrial application products and created a precedent for the application of highly efficient phase change cooling technology in the field of supercomputers.
As the first heterogeneous cluster system in China with actual performance exceeding one trillionths of a second, Shenteng 7000 is the main computing resource of the supercomputing environment of the Chinese Academy of Sciences and the main node of the North China Grid. The cooling capability of high-performance computing nodes has become one of the key issues for whether the ShenTeng 7000 can guarantee the safety and maintain the computing capability in the coming years. To meet the needs of future scientific computing and development of super cloud computing applications, the urgent need for deep The 7000 system cooling system is upgraded.
Under the key support of the Chinese Academy of Sciences, the Evaporative Cooling Research Team of the Institute of Electrical Engineering used the methods of canceling all fans to install the spray evaporation cooling system in each cabinet for the distribution and structural characteristics of the heat source of the supercomputer, and completed the implementation of the product. Two cabinet-type spray evaporative cooling supercomputers successfully passed the Linpack (HPL) test of the entire system for more than 72 hours. The actual measured value of PUE is 1.29, which is 40% lower than the best PUE value of the global supercomputer center. System power consumption.
The success of this project has fundamentally solved the noise pollution caused by air-cooled high-speed fans. Compared with traditional air-cooled and water-cooled technologies, the project has the advantages of high cooling efficiency, uniform temperature distribution, low noise, low power consumption, and high reliability. Provides a leading-edge green thermal management solution for supercomputer cooling and cooling needs.
In addition to its use in supercomputing devices, the evaporative cooling research team of the Electrician has developed a soaking self-circulating evaporative cooling system for high-end server applications, and developed an adherent self-circulating evaporative cooling system for applications in PCs and high-end graphics cards. The system further reduces cooling energy consumption. The thermal management technology centered on evaporative cooling technology has been realized in special motors, turbine generators, transformers, rectifier systems, frequency converters due to its significant cooling performance, balanced temperature control, high reliability, and energy saving and environmental protection. The long-term successful application in China has now become a brand new means to replace traditional cooling solutions in the industrial sector.
