Definitions
- the invention relates to a method for producing isolated bodies and to the construction of bodies produced by this method.
- a special field of application of the invention is exhaust systems for motor vehicles, in particular the manifolds and pipes, and silencers of these exhaust systems.
- a further area of application of the invention is pipes, as are used, for example, in the food industry or the catering trade and in which temperature or sound insulation is to be implemented with high demands on the quality of the view.
- High-performance manifolds are made of stainless steel and optimized for gas flow. Their heat radiation represents a problem that has not yet been solved, since the optimized shape means that distances to other construction parts must be taken into account. The heat radiation can be reduced by isolating the elbow, but the external appearance of the stainless steel is lost due to the insulating material. However, this is often not accepted by the customer.
- FR 1 3471 65 A It is also known from FR 1 3471 65 A a method for producing insulated bodies, the bodies being provided with temperature and / or sound insulation, a layer of insulating material being applied to the surface of the body by winding and onto the surface of the wound Insulating material is applied a metal layer.
- the invention is therefore based on the object of providing a method and an insulated body with which good insulation against heat and sound is ensured with a high quality of appearance, a long service life is guaranteed and the manufacture can be carried out simply and inexpensively.
- a particular advantage of the invention is that the insulated bodies have a high quality of appearance and give the impression of a solid metal surface, which is achieved in that a layer of insulating material is applied to the surface of the body by winding and on the surface of the wound insulating material a metal layer is applied.
- the insulated body is simple and inexpensive to manufacture and consists only of a metal shell enclosing a cavity, an insulating layer wound on the metal shell and at least one metal layer covering the insulating layer.
- Insulating material for example a silicate or mineral wool in the form of a ribbon, wrapped around the stainless steel or structural steel pipes in such a way that a smooth surface is produced.
- This surface made of the insulating material is metallized by means of flame, electrical or plasma application spraying or by chemical deposition.
- a layer thickness in the range of 300 to 900 ⁇ m is sufficient to be heat-resistant, corrosion-resistant and of good visual appearance.
- Multi-layer technology makes it easy to achieve different colors or surfaces.
- the spraying can be done by hand or by spraying robots in a suction cabin. When using Spraying robots can be easily programmed using computer technology for a wide variety of implementations.
- Fig. 2 is a sectional view of a silencer part.
- a pipe part of a manifold of a sports exhaust system consists of a metal shell 2 enclosing a cavity 1, on which an insulating layer 3 of insulating material is wound.
- the insulating material is a silicate prepared in the form of a ribbon.
- a metal layer 4 is sprayed onto the wound insulating layer 3, which in the present exemplary embodiment has a thickness of 500 ⁇ m.
- the sprayed-on metal layer 4 gives the visual impression of a solid stainless steel tube.
- multi-layer technologies it is possible to realize 0 different colors of the metal layer. For example, it is possible to create blue tones.
- the surface roughness can be influenced in a targeted manner by selecting the powder granularity, that is to say the size of the powder particles. Analogous to spraying, chemical deposition of the metal layer 5 is also possible.
- FIG. 2 shows a part of a high-performance rear silencer which, in addition to its inner sound-reducing components, consists of a perforated stainless steel tube 2a which is wrapped with stainless steel wool 5.
- An insulating layer 3 made of insulating material is wound and fastened around the stainless steel wool 5.
- the surface of the insulating material is metallized analogously to the exemplary embodiment shown in FIG. 1 by metal spraying.
- Layer thickness of the metal layer 4 of approx. 500 ⁇ m a complete protective surface with very good optical effects.
- the production of the rear silencer is significantly simplified by this manufacturing method, and in addition the weight of the rear silencer is considerably reduced.
- the invention is not restricted to the exemplary embodiments shown here. Rather, it is possible to implement further design variations by combining and modifying the means and features mentioned without leaving the scope of the invention.
- the invention can therefore also be used wherever pipes are used, which heat and / or soundproofing is to be used.
