en.Wedoany.com Reported - The "Lingsheng" fully domestically produced supercomputer deployed by China's National Supercomputing Center Shenzhen Phase II achieves a sustained computing performance of over 2E Flops, reaching world-leading levels and marking a landmark achievement in full-stack independent control of China's high-end computing sector. China IPPR, under the China National Machinery Industry Corporation (Sinomach), undertook the overall engineering design contracting for the project and built the world's largest centralized liquid cooling system, successfully solving the technical challenge of high energy consumption in exascale supercomputing.
This liquid cooling system adopts a centralized cooling distribution unit (CDU) architecture, enabling centralized management of the entire system's cooling. The secondary side pipeline has a total length of 3,214.7 meters, with a system net weight of 243.9 tons, ensuring precise and controllable hydraulic balance. The project employs a high-temperature liquid cooling solution, featuring a main ring pipe with a cross-section of 1,200 millimeters, matched with a circulating water pump with an electrical power of up to 315 kilowatts, accurately delivering a total cooling capacity of 57,900 kilowatts. A single plate heat exchanger achieves a heat exchange capacity of up to 8,700 kilowatts. Traditional air-cooled data centers typically have a power usage effectiveness (PUE) between 1.3 and 1.5, while this system, with its precisely designed liquid cooling circulation architecture, reduces the PUE value to below 1.2.
Meanwhile, the project introduces a 14-circuit 20kV high-voltage DC power distribution system with a full-link redundancy architecture, ensuring stable output of 2E-level computing power. This power system is deeply coupled with the liquid cooling system, together forming the "blood circulation" and "neural center" of the supercomputing center. The National Supercomputing Center Shenzhen Phase II project is a major scientific facility where China IPPR continues to provide services after completing the design of Phase I.
China IPPR stated that it will continue to leverage scientific research innovation to drive technological advancement, improve energy conversion efficiency, support the deployment of large-scale domestically produced supercomputing and intelligent computing systems, deeply participate in the "East Data West Computing" initiative, and contribute to building the nation's digital infrastructure.
