摘      要：This paper presents design and simulation of a switchable radiative cooler that exploits phase transition in vanadium di-oxide to turn on and off in response to *** cooler consists of an emitter and a solar reflector separated by a *** emitter and the reflector play a role of emitting energy in mid-infrared and blocking incoming solar energy in ultraviolet to near-infrared regime,*** of the phase transition of doped vanadium dioxide at room tem-perature,the emitter radiates its thermal energy only when the temperature is above the phase transition *** feasibility of cooling is simulated using real outdoor *** confirme that the switchable cooler can keep a desired temperature,despite change in environmental conditions.
