Embodiment Construction

[0040] figure 1 A cross-sectional view showing a heat shield plate of a first embodiment of the present invention. The heat shielding plate of this embodiment is used for shielding the heat component 1 that emits heat radiation. The heat shield comprises an inner sheet metal layer 3 with a through-hole 2 forming a perforation. The outer sheet metal layer 4 is bent around the perforated sheet metal layer 2 in such a way that a hollow space is formed therebetween. According to the invention, the hollow space is filled with a metallic hollow body 5 which, in the illustrated embodiment, has a shape comprising, for example, a spherical or elliptical shape.

[0041] Since the hollow bodies 5 themselves and the spaces between the hollow bodies 5 have a high percentage of gas or air, the hollow bodies 5 have low thermal conductivity or good insulation, while at the same time providing a thermal shield with a low overall weight plate. The thinnest possible wall thickness of the hollo...

Abstract

A shield is disclosed, comprising a perforated inner sheet-metal layer (3); an outer sheet-metal layer (4), wherein a cavity delimited by the perforated inner sheet-metal layer and the outer sheet-metal layer is defined; and a plurality of metallic hollow bodies (5) in the cavity, wherein the minimum diameter of the hollow bodies is larger than the perforation (2) of the inner sheet-metal layer.

Description

technical field [0001] The invention relates to a device for shielding temperature-sensitive components facing a heat source, such as the engine compartment of a motor vehicle, in particular as exhaust-carrying components exposed to considerable radiant heat. Additionally, the unit includes a sound deadening and soundproofing design. In particular, the invention relates to a device that is reusable without additional expenditure and can be used as an enclosure or as a partial shield. Background technique [0002] In the automotive industry, thermal shields are mainly used to perform the task of temperature shielding. This heat shield protects vehicle components from heat emanating from the engine, catalytic converter, muffler, exhaust train or other high temperature components. The protected components are mainly located in the engine compartment or in the subfloor. This includes, for example, plastic components, electronic components or fluid transfer ducts in the engine...
