我国制冷技术新突破

Core Viewpoint - The discovery of the "dissolution pressure card effect" by a research team at the Institute of Metal Research, Chinese Academy of Sciences, presents a new low-carbon and efficient cooling solution for high-energy-consuming data centers, potentially transforming cooling technologies in the digital economy era [1][5]. Group 1: Breakthrough in Cooling Technology - The "dissolution pressure card effect" allows for significant temperature drops, with the solution's temperature decreasing by nearly 30°C within 20 seconds under pressure changes, outperforming known solid-state phase change materials [1][2]. - This effect combines the refrigerant and heat transfer medium, utilizing the solution's flow for efficient heat transfer while providing substantial cooling through the dissolution and precipitation process, addressing the long-standing "low-carbon, high cooling capacity, high heat transfer" dilemma in refrigeration [1][2]. Group 2: Engineering Application Potential - The research team has designed a four-step cycle system based on the "dissolution pressure card 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, showcasing excellent engineering application potential [4].
