All metalic thermal insulation assembly - has series of layers with profiled uniform thickness spaced corrugated sheets (SW 3.1.77)

摘要

The all-metallic thermal insulation assembly is constructed from a series of layers each having several spaced corrugated sheets. Each of the sheets is formed from material having the same thickness. The sheets are so profiled as to provide a very high moment of inertia per unit length and be free of deformation except from certain pressure ranges. A series of spaced planar sheets extend between the adjacent corrugated insulating device to thermally insulate the pressurized duct. This is effected along the remainder of the enclosure not insulated by corrugated insulation.
