Title: Passive-solar directional-radiating cooling system

Abstract

A new type of radiative cooling system is described. The radiator makes use of nonimaging optics and evacuated-tube technology to radiate significant amounts of heat to the 3 K environment of outer space. The nonimaging optics are used to direct the radiation overhead, through the most transparent part of the 8 to 13 micron atmospheric window. The required optical concentration is small, and relatively simple mirror geometries are possible. The evacuated-tube technology is used to attain storage temperatures at or below the freezing point, even when dewpoint temperatures are well above the freezing point. The radiator is passively coupled to an ice or ice/clathrate storage tank by a thermal diode. Storage duration may be either diurnal or seasonal.
