Abstract
A method of making thermal shield (20) having a first plate (22) and a second plate (24) with an interior chamber (26) positioned in between. The method includes a seam (40) extending around the periphery of the thermal shield which prevents the ingress of fluid into the interior chamber. The seam is formed to include portions (60 and 72) that extend at least partially, and preferably completely, around the outer surface (56) of a shoulder (54) of the seam. The method may be used to form a seam (40) that is capable of sealing a pressure differential between the interior chamber and the regions surrounding the thermal shield of up to about 40 psi.
Claims15
A thermal shield, comprising:
- a. a first plate having a first peripheral region;
- b. a second plate having a second peripheral region;
- c. an interior chamber enclosed by said first plate and said second plate;
- and
- d. a seam made exclusively from said first peripheral region and said second peripheral region, wherein said seam seals said interior chamber such that fluids cannot travel between said interior chamber and the region surrounding the thermal shield unless there is a pressure differential between said interior chamber and the region of at least 10 psi.
A thermal shield, comprising:
- a. a first plate having a first peripheral region;
- b. a second plate having a second peripheral region;
- c. an interior chamber enclosed by said first plate and said second plate;
- and
- d. means for sealing the thermal shield at said first peripheral region and said second peripheral region such that a fluid cannot travel between said interior chamber and the region surrounding the thermal shield unless there is a pressure differential between said interior chamber and the region of at least 10 psi.
An automobile, comprising:
- a. a heat source;
- and
- b. a thermal shield proximate said heat source, said thermal shield including:
- i. a first plate having a first peripheral region;
- ii. a second plate having a second peripheral region;
- iii. an interior chamber enclosed by said first plate and said second plate;
- and
- iv. a seam made exclusively from said first peripheral region and said second peripheral region, wherein said seam seals said interior chamber such that fluids cannot travel between said interior chamber and the region surrounding the thermal shield unless there is a pressure differential between said interior chamber and the region of at least 10 psi.
