Recently, a research team from Xidian University has achieved a major breakthrough in chip thermal management, successfully solving a long-standing global challenge in the semiconductor industry. As chip performance continues to advance, power consumption and heat generation have surged, outpacing the capabilities of conventional cooling technologies. The Xidian team innovatively developed a highly efficient cooling solution that integrates micro-nano structures with phase-change materials. By constructing a three-dimensional microchannel network within the chip and combining it with high-thermal-conductivity phase-change materials, the team significantly enhanced heat conduction and dissipation. Experimental results show that this technology reduces hotspot temperatures by over 30%, while also extending device lifespan and improving system stability. This advancement provides critical support for high heat-flux applications such as high-performance computing, AI chips, and 5G communication devices, marking China’s entry into the global forefront of advanced thermal management technologies. The research has been published in top-tier international journals and secured multiple national invention patents, demonstrating strong potential for industrial application.
