Abstract

All-metal heat insulation, including building blocks which can be joined together, the building blocks each including metallic foils being thermally movably supported and mutually spaced apart from each other forming insulating cells therebetween, spacer strips for maintaining the mutual spacing between the foils, and at least two housing plates at least partly surrounding the foils and spacer strips and being disposed at a given distance from each other, the spacer strips being adjacent to each other and being fastened to at least one of the housing plates, the spacer strips being mutually spaced apart from each other at a distance at least equal to the thickness of one foil forming receiving pockets for the foils at least at one of the plates, the foils being shorter than the given distance between the housing plates and being slideably fitted in the receiving pockets.

Claims

1. All-metal heat insulation, comprising building blocks which can be joined together, said building blocks each including metallic foils thermally movably supported and mutually spaced apart from each other forming insulating cells therebetween, said building blocks being substantially cube-shaped and said foils being substantially parallel to each other, spacer strips for maintaining said mutual spacing between said foils, and at least two housing plates at least partly surrounding said foils and spacer strips and being disposed at a given distance from each other, said spacer strips being adjacent to each other and being fastened to at least one of said housing plates, said spacer strips being mutually spaced apart from each other at a distance at least equal to the thickness of one foil forming receiving pockets for said foils at least at one of said plates, said foils being shorter than said given distance between said housing plates and being slideably fitted in said receiving pockets.

2. All-metal heat insulation, comprising building blocks which can be joined together, said building blocks each including metallic foils thermally movably supported and mutually spaced apart from each other forming insulating cells therebetween, spacer strips for maintaining said mutual spacing between said foils, and at least two housing plates at least partly surrounding said foils and spacer strips and being disposed at a given distance from each other, said spacer strips being adjacent to each other and being fastened to at least one of said housing plates, said spacer strips being mutually spaced apart from each other at a distance at least equal to the thickness of one foil forming receiving pockets for said foils at least at one of said plates, said foils being shorter than said given distance between said housing plates and being slideably fitted in said receiving pockets, said foils having four sides and said receiving pockets being disposed at each of said four sides for thermally movably retaining said foils thereat.

3. All-metal heat insulation, comprising building blocks which can be joined together, said building blocks each including metallic foils thermally movably supported and mutually spaced apart from each other forming insulating cells therebetween, spacer strips for maintaining said mutual spacing between said foils, and at least two housing plates at least partly surrounding said foils and spacer strips and being disposed at a given distance from each other, said spacer strips being adjacent to each other and being fastened to at least one of said housing plates, said spacer strips being mutually spaced apart from each other at a distance at least equal to the thickness of one foil forming receiving pockets for said foils at least at one of said plates, said foils being shorter than said given distance between said housing plates and being slideably fitted in said receiving pockets, said foils having one bent side welded to one of said housing plates and other sides thermally movably retained in said receiving pockets.
