The panel comprises at least two layers of material (1) separated with a gap (2) and tightly closed at the panel's edges. The adjoining material layer (1) surfaces are covered with the coating (3) made of gastight material of a high reflectivity coefficient. The material layers (1) are fixed relative to each other by means of distancing units, each of which possesses a bearing element (4) and two complexes of mutually embedded shells (5, 6, 7, 8). The shells are suspended on the ends of the bearing element (4) and relative to each other by tension strings (9), each of which is wound around the end of the bearing element (4), the edge of the inner shell (5) and consecutively through the bottom of the smaller shell (6) and the edge of the larger shell (7) of the complex, while the ends are fixed to the outer shell (8). The panel is equipped with the gas evacuation pipe (10), tightly fastened to the coating (3), leading through the material layer (1) to the outside and ending with the cutting-off element (11). In the gap (2) between the material layers (1) a high vacuum is obtained. |
