| 摘要 |
The present invention is directed to thermal insulation elements each formed of a structural material with a highly emittant surface having a geometric shape of a repetitive three dimensional design which permits alternate stacking of one thermal insulation element alternately with another thermal insulation element and which locks movement of adjacent thermal insulation elements in at least one of the directions 90 DEG to the stacking direction; and more specifically, to a thermal insulation barrier having at least three alternately stacked thermal insulation elements, two of the thermal insulation elements having the same design, the alternate thermal insulation element having a complementary design, whereby when the thermal insulation elements are alternately stacked, any point of contact between thermal insulation elements is a contact between the alternate thermal insulation element and only one of the other thermal insulation elements. The present invention is also directed to a panel which has a rigid multi-layer thermal insulation barrier supporting an envelope of thin skin high gas barrier material which is evacuated.
