Embodiment Construction

[0023] Figure 1 shows a perspective view of an insulating panel with a design suitable for use. The heat insulating board comprises a plate-shaped part 1 , also referred to simply as a “plate” below, on which slot-shaped holes 2 are distributed. The distribution of said slotted holes 2 lies within the range of normal industry practice; in particular, the free perforation area 3 may have fastening holes 4 for supporting fastening means. These free perforation areas 3 can also be used for inscriptions or for reliable production. It falls within the normal industry practice to also provide this type of plate 1 with a bead 5 to further enhance the mechanical stability of the plate 1 .

[0024] The thermal insulation panel preferably comprises a non-corrosive panel 1 made, in particular, of aluminum. Aluminum sheets with a thickness of 0.3 to 0.5 mm are preferably used. Of course, the plate may also comprise aluminum foil with a thickness of eg 0.1 to 0.3 mm or a thick aluminum ...

Abstract

The sound-absorbing insulation part is used everywhere where sound and / or heat sources have to be shielded, preferably in automotive engineering as a heat shield. This insulation part comprises at least one dimpled sheet-shaped element (1) which is provided with hardening embossings (8). These hardening embossings (8) have an embossing bottom (10) and embossing flanks (11). According to the invention, the sheet-shaped element (1) exhibits material compression, that is to say material hardening (13), in the region of the embossing flanks (11). Fissures (9) which have a bizarrely shaped contour can lie in the embossing bottoms (10). These fissures (9) are produced by stretching and tearing of the embossing bottom (10), that is to say they have a wavy and irregular contour (19).

Description

technical field [0001] The invention relates to a sound-absorbing partition according to the preamble of claim 1 . Background technique [0002] Isolators of the type described above are used where all sources of sound and / or heat must be isolated. These spacers are suitable for use within the structure of the car and are placed there, for example between a heated catalytic converter and the vehicle floor. [0003] Spacers of this type are known and described, for example, in applications WO 91 / 10560, WO 00 / 46493 or German application 10 2005 006 164 A1. [0004] WO 91 / 10560 describes a thermal insulation panel having a metal foil layer comprising a thermally conductive area, called a heat dissipation area, and a thermally insulating area. In particular, the individual foil layers of the metal foil layers have studs which separate the stacked metal foil layers from one another. The individual metal foil layers may be interconnected in a hermetically sealed manner, thereby...
