THERMO-INSULATING STRUCTURE

Abstract

An invention relates to a field of mechanical structures intended to suppress free convection in rectangular cavities and, at the same time, to diminish infrared radiation through these mechanical structures. A thermo-insulating structural unit comprises following units: a rectangular frame constructed from two opposite transverse strips and two opposite longitudinal strips; the most part of each longitudinal strip is corrugated; a set of first parallel lines, which are joined with the vertices of the corrugations of the opposite longitudinal strips; a set of second parallel lines, which are joined with the valleys of the corrugations of the opposite longitudinal strips; a flexible film, which is situated between the first and second lines in such a manner that this flexible film walks around the second parallel lines on their underside and the first parallel linesfrom above.

In one embodiment the flexible film is transparent or translucent.
