The application of polymeric and composite materials in two-phase passive heat transfer devices is reviewed critically, with a focus on advantages and disadvantages of these materials in thermal management systems. Recent technology developments led to an increase of the power density in several applications including portable electronics, space and deployable systems, etc., which require high-performance and compact thermal management systems. In this context, passive two-phase systems are the most promising heat transfer devices to dissipate large heat fluxes without external power supply. Usually, heat transfer systems are built with metals due to their excellent thermal properties. However, there is an increasing interest in replacing metallic materials with polymers and composites that can offer cost-effectiveness, light weight and high mechanical flexibility. The present work reviews state-of the-art applications of polymers and composites in two-phase passive thermal management systems, with an analysis of their limitations and technical challenges.
本文对聚合物和复合材料在两相被动传热装置中的应用进行了批判性综述，重点关注这些材料在热管理系统中的优缺点。近期的技术发展使得包括便携式电子产品、太空和可展开系统等多种应用中的功率密度有所提高，这就需要高性能且紧凑的热管理系统。在这种背景下，被动两相系统是最有前景的传热装置，能够在无需外部电源的情况下消散大量热通量。通常，传热系统由于金属具有优异的热性能而采用金属构建。然而，人们越来越有兴趣用聚合物和复合材料替代金属材料，因为它们具有成本效益、重量轻和高机械柔韧性等优点。本工作综述了聚合物和复合材料在两相被动热管理系统中的最新应用，并分析了它们的局限性和技术挑战。
