Multilayer metal foil pads or panels for heat or sound insulation or shielding comprising two or more corrugated metal foil or metal sheet layers wherein a flat metal foil or metal sheet layer is positioned between each pair of corrugated layers. The corrugated layers and/or the flat layers may be embossed, patterned or textured to enhance performance of the pad or panel. A preferred pad or panel comprises an embossed, patterned or textured flat exterior layer adapted for contacting the surface to be insulated or shielded to provide air space between the pad or panel and the surface and to separate the first corrugated layer from the surface. Methods are provided for making the pads and panels, which are useful in automotive applications, food cooking devices and other uses.

Corrugated multilayer metal foil insulation panels and methods of making

A forge/swage formed three dimensional multilayer metal foil shield having areas therein where the layers are in a spaced apart relationship, areas therein where the layers are tensioned or stretched, and areas therein where the layers are compressed and interlocked together by folding, rolling, wrinkling, curling, coiling, crimping and the like. The multilayer metal foil shield is formed by forge/swage shaping in an appropriate mold apparatus a preform of a stack of metal foil layers having gaps between the layers. The gaps are provided by embossments in the layers or by spacers between the layers. The forge formed multilayer metal foil shields have utility as heat shields and acoustic shields, particularly on vehicles. The forge formed multilayer metal foil shields are mounted on automobile underbody areas, such as the bottom of the floor pan of the passenger compartment, to provide heat and sound insulation. Other automotive uses include fire wall, exhaust tunnel, motor mount and exhaust down pipe. The three dimensional shields include multilayer metal sheet formed structures. Intermediate beaded or rolled edge multilayer metal preforms are made for transport to the final three dimensional stamping operation.

Shaped multilayer metal foil shield structures and method of making

A portable gas grill features a combination of quick heat up and quick cool down in a compact and truly portable self contained grill for camping, tailgating, and other activities. The gill includes a lower housing containing a multilayer metal foil insulation/reflector member, a grill surface, a radiant heating element, and a grill cover with a multilayer metal foil insulating/reflector member. The radiant heating element utilized in the gas grill includes a gas jet burner in combination with a heat radiating tube which contains the flame extending from the jet burner. The radiant heat generated by the radiant heating tube heats a grill surface of 170 square in. or greater to adequate grilling temperatures such as 700&deg; F. and higher.

A heated container for transport of prepared hot food has a combination of an electric heating element with an insulation layer comprising metal foil layers and fiber layers. The combination of metal foil layers, which spread the heat from the heating element, and the fiber insulation layers provides an efficient food transport container having sufficiently low power requirements to enable powering the heater element from an automotive 12 volt system while maintaining a food temperature inside the container at about 150&deg; F.

Food transport container with integral heater

The invention provides a grill configuration which enables a 2400 Watt or smaller electric heating element to provide cooking temperatures of at least 500.degree. F. when food is present on a grill area of at least 200 square inches. The electric grill includes an electric heating element and a multilayer metal sheet insert shaped to reflect radiation heat from the heating element to impinge on the food present on the grill surface. The multilayer metal sheet insert is preferably metal foil layers which provide maximum insulation and heat containment to increase the efficiency of the limited heat available from the electric heating element of the grill.

Electric barbecue grill

A multilayer metal sheet-polymer composite wherein the multilayer metal sheet side provides heat resistance and heat protection for the polymer side. The multilayer metal sheet component preferably comprises aluminum or stainless steel foils bonded to the polymeric component to form articles such as, conduits, panels, equipment housings and cooking devices.

Bonded metal-plastic composite structures

A forge/swage formed three dimensional multilayer metal foil shield having areas therein where the layers are in a spaced apart relationship, areas therein where the layers are tensioned or stretched, and areas therein where the layers are compressed and interlocked together by folding, rolling, wrinkling, curling, coiling, crimping and the like. The multilayer metal foil shield is formed by forge/swage shaping in an appropriate mold apparatus a preform of a stack of metal foil layers having gaps between the layers. The gaps are provided by embossments in the layers or may be provided by spacers between the layers. The forge formed multilayer metal foil shields have utility as heat shields and acoustic shields, particularly on vehicles. The forge formed multilayer metal foil shields are mounted on automobile underbody areas, such as the bottom of the floor pan of the passenger compartment, to provide heat and sound insulation. Automotive uses include fire wall, exhaust tunnel, motor mount and other heat and sound shielding locations.
