    • A structure and method for changing or controlling the thermal emissivity of the surface of an object in situ, and thus, changing or controlling the radiative heat transfer between the object and its environment in situ, is disclosed. Changing or controlling the degree of blackbody behavior of the object is accomplished by changing or controlling certain physical characteristics of a cavity structure on the surface of the object. The cavity structure, defining a plurality of cavities, may be formed by selectively removing material(s) from the surface, selectively adding a material(s) to the surface, or adding an engineered article(s) to the surface to form a new radiative surface. The physical characteristics of the cavity structure that are changed or controlled include cavity area aspect ratio, cavity longitudinal axis orientation, and combinations thereof. Controlling the cavity area aspect ratio may be by controlling the size of the cavity surface area, the size of the cavity aperture area, or a combination thereof. The cavity structure may contain a gas, liquid, or solid that further enhances radiative heat transfer control and/or improves other properties of the object while in service.
    • 公开了一种用于改变或控制物体表面的热辐射率的原位结构和方法,从而改变或控制物体与其原位环境之间的辐射热传递。 通过改变或控制物体表面上的空腔结构的某些物理特性来改变或控制物体的黑体行为程度。 限定多个空腔的空腔结构可以通过从表面选择性地去除材料而形成,选择性地向表面添加材料,或者将工程制品添加到表面以形成新的 辐射表面。 改变或控制的空腔结构的物理特性包括空腔面积纵横比,腔纵轴取向及其组合。 控制空腔面积纵横比可以通过控制空腔表面积的大小,空腔开口面积的大小或其组合。 空腔结构可以包含气体,液体或固体,其在使用中进一步增强辐射热传递控制和/或改善对象的其它性质。
