Abstract
A heat shield has a first layer, a second layer and a third layer. The first layer may have an outer surface and an inner surface. The second layer may have a first inner surface and a second inner surface. The third layer may have an inner surface and an outer surface, where the outer surface is defined by a plurality of dimples.
Claims19
A heat shield, comprising:
- a first layer having an outer surface and an inner surface opposite said outer surface, said inner and outer surfaces defining a constant thickness between them, wherein said inner and outer surfaces are entirely continuous and smooth;
- a second layer having a first inner surface and a second inner surface opposite said first inner surface, said first and second inner surfaces defining a constant thickness between them, wherein said first and second inner surfaces are entirely continuous and smooth, wherein said first layer inner surface is in complete, continuous and direct contact with said second layer second inner surface;
- and
- a third layer having an inner surface and an outer surface, wherein said outer surface is defined by a plurality of dimples, wherein troughs of the dimples are in direct contact with said first inner surface of said second layer, wherein air gaps separate said dimples from one another, wherein said inner and outer surfaces of said third layer define a constant thickness for said plurality of dimples and said third layer.

A heat shield, comprising:
- a first metallic layer having an outer surface and an inner surface opposite said outer surface, said inner and outer surfaces defining a constant thickness between them;
- a second nonmetallic layer having a first inner surface and a second inner surface opposite said first inner surface, said first and second inner surfaces defining a constant thickness between them;
- and
- a third metallic layer having an inner surface and an outer surface, wherein said outer surface is defined by a plurality of dimples having only troughs that extend toward said second layer, wherein said troughs of the dimples are in direct contact with said first inner surface of said second layer, wherein said inner and outer surfaces of said third metallic layer define a constant thickness for said plurality of dimples and said third metallic layer.
