  • Radiative cooling device including paint coating layer composed of nano or micro particles
    Patent number: 11703290
    Abstract: The present invention relates to a technique of cooling a temperature on the surface or under a material by emitting heat under a radiative cooling device to the outside while minimizing the absorption of light in a solar spectrum by forming a paint coating layer with excellent radiative cooling performance on various surfaces. A radiative cooling device according to an embodiment of the present invention may include a paint coating layer formed by coating or dyeing on various surfaces a paint solution mixed with nano or microparticles of which a particle size and a composition are determined in consideration of infrared emissivity and reflectance to incident sunlight in a wavelength range corresponding to a sky window and a binder mechanically connecting the surfaces of the nano or microparticles in a solvent.
