| 摘要 |
<p>The invention relates to a thermal insulation panel (1), comprising a gastight housing manufactured substantially from rectangular walls (2) and a filling arranged inside the housing and resistant to pressure forces, wherein the pressure is reduced in the interior of the housing to a level at which no heat transport of any significance takes place, wherein at least the walls of the housing which have a direction coinciding with the temperature gradient (3,4) comprise a wall part located at some distance from the ribs which is made thinner relative to the thickness of the wall adjacently of the ribs. It will be apparent that reducing the wall thickness will reduce the temperature conduction to a great extent. The reduction in the wall thickness (5,6) herein does not generally result in a reduction in the strength of the panel, or hardly so; this is in any case largely determined by the degree of compressibility of the filling. <IMAGE></p> |
