Panels for industrial dryers and other heated enclosures having stainless steel end structural sheet elements

Claim 2

A structural heat-insulation panel for high temperature industrial dryers and such other heated enclosures comprising inner and outer opposed metallic sheets in generally parallel, spaced-apart planes, one of said sheets being exposed to higher temperature than the other sheet, said sheets defining a space therebetween; insulation means in said space; end structural sheet elements connecting said inner and outer sheets together and enclosing said space; said end sheet elements having sufficient strength to act as load bearing members between the inner and outer sheets; said end sheet elements being of low heat conductivity stainless steel.

Claim 3

The panel of claim 1 wherein said end structural elements are of 300-series stainless steel.

Claim 4

A structural heat-insulation panel for high temperature industrial dryers and such other heated enclosures comprising inner and outer opposed metallic sheets in generally parallel, spaced-apart planes, one of said sheets being exposed to higher temperature than the other sheet, said sheets defining a space therebetween; insulation means in said space; end structural sheet elements connecting said inner and outer sheets together along lines of connection and enclosing said space; said end sheet elements having sufficient strength to act as load bearing members between the inner and outer sheets and being of low heat conductivity stainless steel; said end sheet elements or panels or both being embossed along said lines of connection to reduce the heat flow between the inner and outer panels.

Claim 5

A structural heat-insulation panel for high temperature industrial dryers and such other heated enclosures comprising inner and outer opposed metallic sheets in generally parallel, spaced-apart planes, one of said sheets being exposed to higher temperature than the other sheet, said sheets defining a space therebetween; insulation means in said space; end structural sheet elements connecting said inner and outer sheets together along lines of connection and enclosing said space; said end sheet elements having sufficient strength to act as load bearing members between the inner and outer sheets and being of low heat conductivity stainless steel; said end sheet elements or panels or both being embossed along said lines of connection to reduce the heat flow between the inner and outer panels.

Claim 6

The panel of claim 3 wherein said end structural elements are of 300-series stainless steel.

Claim 7

A structural heat-insulation panel for high temperature industrial dryers and such other heated enclosures comprising inner and outer opposed metallic sheets in generally parallel, spaced-apart planes, one of said sheets being exposed to higher temperature than the other sheet, said sheets defining a space therebetween; insulation means in said space; end structural sheet elements connecting said inner and outer sheets together along lines of connection and enclosing said space; said end sheet elements having sufficient strength to act as load bearing members between the inner and outer sheets and being of low heat conductivity stainless steel; said outer sheet being painted on its outer surface with a heat emissive paint.

Claim 8

A structural heat-insulation panel for high temperature industrial dryers and such other heated enclosures comprising inner and outer opposed metallic sheets in generally parallel, spaced-apart planes, one of said sheets being exposed to higher temperature than the other sheet, said sheets defining a space therebetween; insulation means in said space; end structural sheet elements connecting said inner and outer sheets together along lines of connection and enclosing said space; said end sheet elements having sufficient strength to act as load bearing members between the inner and outer sheets and being of low heat conductivity stainless steel; said outer sheet being painted on its outer surface with a heat emissive paint.

Claim 9

The panel of claim 5 wherein said end structural elements are of 300-series stainless steel.

Claim 10

The panel of claim 6 wherein said lines of connection between the inner and outer sheets and end structural elements are noncontinuous to reduce thermal conductivity.

Claim 11

The panel of claim 7 wherein said end structural elements or inner and outer panels or both are embossed along said lines of connection to reduce the heat flow between the inner and outer panels.
