    • A method and radiative cooling device 10 for use in passively cooling spaces, applicable to any level of thermal radiation in vacuum and to high-intensity thermal radiation in non-vacuum environments. The device includes an enclosure 12 nested in a multiplicity of thin, low-emittance, highly-reflective shields 13 and 13' suspended in a casing 14 in mutual angular relation and having V-shaped spaces defined therebetween for redirecting, by reflection, toward the large openings of the V-shaped spaces, thermal radiation entering the sides of the shields, and emitted to the spaces, whereby successively reduced quantities of thermal radiation are reflected by the surfaces along substantially parallel paths extended through the V-shaped spaces to a common heat sink such as the cold thermal background of space.
    • 一种用于被动冷却空间的方法和辐射冷却装置10,可应用于真空中的任何水平的热辐射和非真空环境中的高强度热辐射。 该装置包括嵌套在以相互角度关系悬挂在壳体14中的多个薄的,低发射度的高反射屏蔽13和13'中的壳体12,并且具有限定在其间的V形空间,用于通过反射来重定向 V形空间的大开口,进入屏蔽侧面的热辐射,并且发射到空间,由此连续减少量的热辐射被基本平行的通过V形空间延伸的平行路径的表面反射到共同的 散热器如冷热背景的空间。
