Radiative thermal management technologies that utilize thermal radiation from nano/microstructure for cooling and heating have gained significant attention in sustainable energy research. Passive radiative cooling and solar heating operate continuously, which may lead to additional heating or cooling energy consumption due to undesired cooling or heating during cold nighttime/winters or hot daytime/summers. To overcome the limitation, recent studies have focused on developing radiative thermal management technologies that can toggle radiative cooling on and off or possess switchable dual cooling and heating modes to realize sustainable and efficient thermal management. This review will explore the fundamental concepts of radiative thermal management and its switching mechanisms, utilizing novel systems composed of various materials and nano/microstructures. Additionally, we will delve into the potential future research directions in radiative thermal management technologies.
利用纳米/微结构的热辐射进行冷却和加热的辐射热管理技术在可持续能源研究中受到了广泛关注。被动辐射冷却和太阳能加热持续运行，这可能会由于在寒冷的夜间/冬季或炎热的白天/夏季出现不期望的冷却或加热而导致额外的加热或冷却能源消耗。为了克服这一限制，最近的研究集中在开发能够开启和关闭辐射冷却或具有可切换的双冷却和加热模式以实现可持续和高效热管理的辐射热管理技术。本综述将探讨辐射热管理的基本概念及其切换机制，利用由各种材料和纳米/微结构组成的新型系统。此外，我们还将深入探讨辐射热管理技术未来潜在的研究方向。
