<p>An insulation panel that is bendable, light in weight, thinner, more durable and a more effective insulator for use on space vehicles, low temperature cryogenic vessels and common household appliances. The ultra-thin compact vacuum insulation panel has two hard, but bendable metal wall sheets (12, 14) closely spaced apart from each other and welded around the edges to enclose a vacuum chamber (15). Glass or ceramic spacers (16) hold the wall sheets apart. The spacers can be discrete spherical beads (16) or monolithic sheets of glass (62) or ceramic webs with nodules (57) which form essentially "point" or "line" contacts with the metal sheets. In the case of monolithic spacers that form "line" contacts, two such spacers (74, 75) with the line contacts running perpendicular to each other form effectively "point" contacts at the intersections. Corrugations accommodate bending and expansion, tubular insulated pipes and conduits, and preferred applications are also included.</p> |
