Abstract
Devices and methods for concentrated radiative cooling using radiative cooling coatings in combination with mid-infrared reflectors. Concentrated radiative cooling (CRC) devices include an object to be cooled that is coated with a radiative cooling material and a mid-infrared (mid-IR) reflector configured to reflect thermal energy radiated from a surface of the object to deep space. The object may be nested in a mid-IR reflective trough such that substantially an entirety of the object's surface area contributes to radiative cooling. The radiative cooling material may be a coating such as a paint or film that is applied directly to the object's exterior surfaces to reduce thermal resistances. The radiative cooling coating is configured to lose thermal energy from the object by means of exhibiting high emissivity for wavelengths of 8 to 13 micrometers, and in some arrangements of 5 to 30 micrometers.
