Abstract: With the increasingly serious energy problems and extreme climate in modern society, radiative cooling technology with zero-energy consumption has attracted much attention from the related scientific community. Since the first experimental demonstration of daytime radiative cooling in 2014, the technology has been widely studied from the perspectives of structural design, material selection, preparation process, integrated application, etc., resulting in the development of various types of devices including coatings, paintings, flexible films, fabrics, etc. New research is putting forward new requirements in terms of scene compatibility, environmental and climate adaptability. So the realization of new types of radiative cooling device that is compatible with multiple scenarios, adaptive to environmental changes, and has dynamic thermal control capabilities is of great significance to the practical application of radiative cooling technology in fields such as energy, medical, and industrial production. This paper focuses on the basic physical principles and photonics structure designs of radiative cooling technology, and summarizes the basic technology of radiative cooling devices and their progress in scene compatibility, temperature adaptive thermal regulation, etc. Firstly, the principle and basic design method of radiative cooling technology are expounded, then some typical radiative cooling structures and the main progress of realizing multi-scenario compatibility and adaptive dynamic regulation of radiative cooling devices are introduced, and at last, the development of radiative cooling devices is summarized and prospected.
