【央视新闻】我国制冷技术新突破 有望推动算力基础设施低碳运行

Group 1 - The core achievement is the discovery of the "dissolution pressure card effect," which offers a low-carbon and efficient cooling solution for high-energy data centers and computing infrastructure [1][3] - The cooling systems in data centers consume nearly 40% of the total electricity, and traditional compression refrigeration methods face efficiency bottlenecks in high-power heat dissipation [1][2] - The new effect allows for a significant temperature drop of nearly 30°C within 20 seconds at room temperature, surpassing the performance of known solid-state phase change materials [1][2] Group 2 - The "dissolution pressure card effect" is likened to a wet sponge that, when compressed, releases heat and absorbs heat rapidly when released, providing a more effective cooling mechanism [2] - A four-step cycle system has been designed based on this effect, achieving a theoretical efficiency of up to 77% and the ability to absorb 67 joules of heat per gram of solution in a single cycle [2] - This breakthrough presents an original method for next-generation data center cooling technology, potentially promoting low-carbon operations in computing infrastructure [3][4]
