VO2 self-adaptive radiation cooling device based on F-P resonant cavity structure and preparation method of VO2 self-adaptive radiation cooling device

The invention discloses a vanadium dioxide self-adaptive radiation cooling device based on an F-P resonant cavity structure and a preparation method of the vanadium dioxide self-adaptive radiation cooling device, and belongs to the technical field of passive radiation cooling. The dynamic radiation cooler comprises a VO2 two-phase mixing layer, an infrared transparent spacing layer and a high infrared reflection layer which are sequentially arranged in an overlapped mode from top to bottom, and the VO2 two-phase mixing layer is arranged in the mode that when the VO2 two-phase mixing layer is in a metal state at the high temperature, radiation refrigeration of the dynamic radiation cooler is started, and radiation refrigeration of the dynamic radiation cooler is started. And when the VO2 two-phase mixing layer is in an insulation state at a low temperature, radiation refrigeration of the dynamic radiation cooler is inhibited. Compared with a traditional static radiation cooling device which has the characteris
