An ultra-thin compact vacuum insulation panel is comprised of two hard, but bendable metal wall sheets closely spaced apart from each other and welded around the edges to enclose a vacuum chamber. Glass or ceramic spacers hold the wall sheets apart. The spacers can be discrete spherical beads or monolithic sheets of glass or ceramic webs with nodules protruding therefrom to form essentially “point”or “line”contacts with the metal wall sheets. In the case of monolithic spacers that form “line”contacts, two such spacers with the line contacts running perpe...
Thermal insulating apparatus, comprising: a plurality of thermal insulating panels, each of which has two closely spaced-apart metallic wall panels with spacers therebetween bridging the two wall panels, such spacers being shaped such that thermal conduction through the spacer sheets must be through near “point”contacts of solid materials, the edges of said wall panels being welded together to form a chamber therebetween, and said chamber being evacuated to a high-grade vacuum having a pressure at least as low as 10-5 Torr; a large, conventional-type ins...
