Abschirmelemente werden u. a. im Bereich der Auspuff anlage des Kraftfahrzeuges eingesetzt und können den Abgaskrümmer, welcher Hitze und Schallwellen abgibt, umkleiden. Herkömmliche Abschirmelemente sind zumeist aus ein- oder mehrlagigem Blech gefertigt. Auch Ab schirmelemente mit einer zwischen zwei Blechlagen angeordneten Zwischenschicht zur Verbesserung der Abschirmeigenschaften sind bekannt. Shielding elements are u. a. in the area of the exhaust plant of the motor vehicle used and can Exhaust manifold, which emits heat and sound waves, change clothes. Conventional shielding elements are mostly made from single or multi-layer sheet metal. Also from screen elements with one between two sheet layers arranged intermediate layer to improve the Shielding properties are known.
Nachteilig beim Stand der Technik ist die Tatsache, daß die von den Abschirmelementen aufgenommene Wärme ungerichtet an die Umgebung abgegeben wird, was den Wirkungsgrad des Motors begrenzt. Außerdem heizen sich die Abschirmelemente selbst teilweise beträcht lich auf, was ihrer Funktion als Hitzeschild abträg lich ist.A disadvantage of the prior art is the fact that the heat absorbed by the shielding elements is delivered to the environment in an undirected manner, causing the Motor efficiency limited. Also heat the shielding elements themselves sometimes considerable Lich on what detracts from their function as a heat shield is.
Ausgehend von diesen und weiteren Nachteilen des Standes der Technik liegt der Erfindung die Aufgabe zugrunde, eine Abschirmung zu schaffen, welche die aufgenommene Wärme nutzbar macht und zudem eine ver besserte Abschirm- und Geräuschdämpfungsfunktion auf weist.Based on these and other disadvantages of the State of the art, the object of the invention to create a shield that the heat is usable and also a ver improved shielding and noise reduction function points.

Ein derartiges Abschirmelement ge stattet aufgrund des mehrschaligen Aufbaus außerdem eine verbesserte Geräuschabschirmung. An at least two-shell shielding element, the zwi a first and an associated two the shell a flow path for the radiated Heat absorbing fluid medium such as gases or Has liquids, and at least an inlet and outlet for the fluid Medium possesses an improved warmth derivation and also allows the utilization of the absorbed heat at a be from the heat source distant place. Such a shielding element ge also equips due to the multi-layer structure an improved noise shield.
Zwischen erster und zweiter Schale können im Flußweg Rippen angeordnet sein, welche die Kontaktfläche zum fluiden Medium vergrößern, so daß ein effizienterer Wärmeübergang und damit eine verbesserte Wärmeab schirmfunktion gewährleistet sind. Die Rippen lassen sich auch zur Strömungssteuerung verwenden und können beispielsweise derart angeordnet sein, daß ein mäan derförmiger Mediumflußweg definiert wird. Auf diese Weise kann die Verweilzeit des fluiden Mediums im Abschirmelement verlängert und die Wärmeaufnahme ge steigert werden. Die Rippen weisen außerdem ge räuschdämmende Eigenschaften auf.Between the first and second shell in the river path Ribs are arranged, which the contact surface to enlarge fluid medium so that a more efficient Heat transfer and thus an improved heat abs screen function are guaranteed. Leave the ribs can also use and can control the flow For example, be arranged such that a meander deriform medium flow path is defined. To this The residence time of the fluid medium in the Shielding element extended and the heat absorption ge be increased. The ribs also have ge noise-reducing properties.
Alternativ oder zusätzlich zu den Rippen kann zwi schen erster Schale und zweiter Schale auch ein Röh rensystem zur Leitung des fluiden Mediums angeordnet sein, welches ebenfalls bevorzugt einen mäanderförmi gen Flußweg definiert.Alternatively or in addition to the ribs, between first shell and second shell also a tube arranged system for directing the fluid medium be, which also preferably a meandering defined river path.
Die ein- oder zur besseren Geräuschdämmung mehrlagig ausgestalteten Schalen können in einem der Wärmequel le zugewandten Bereich eine absorbierende und in ei nem dem fluiden Medium zugewandten Bereich eine re flektierende Oberfläche aufweisen. Die reflektieren den oder absorbierenden Eigenschaften lassen sich beispielsweise durch entsprechende Beschichtungen (mit Aluminium plattierte Bleche, Edelstähle, Bleche mit schwarzer Oberfläche) erzielen.The one or more layers for better noise insulation designed bowls can in one of the heat sources le facing area an absorbent and in egg nem a region facing the fluid medium have a reflective surface. They reflect the or absorbent properties for example by appropriate coatings (sheets clad with aluminum, stainless steels, sheets with black surface).
Bevorzugt sind Eintrittsöffnung und Austrittsöffnung des Abschirmelementes über einen Mediumkreislauf ver bunden, in dem eine Förderpumpe angeordnet sein kann. Durch einen Wärmetauscher im Mediumkreislauf läßt sich die im Abschirmelement vom Medium aufgenommene Wärme an einem anderen Ort, beispielsweise am Motor oder im Fahrgastinnenraum, wieder abgeben. Auf diese Weise läßt sich eine Heizung mit hervorragendem An sprechverhalten realisieren. Unter Umständen kann auf die herkömmlichen Heizsysteme sogar vollständig ver zichtet werden. Im Mediumkreislauf kann weiterhin ein Thermostatventil angeordnet sein, welches eine kon stante Mediumtemperatur gewährleistet.Entry opening and exit opening are preferred of the shielding element via a medium circuit bound in which a feed pump can be arranged. Through a heat exchanger in the medium circuit the medium absorbed in the shielding element Heat in another place, for example on the engine or in the passenger compartment. To this A heating system with excellent on can be wise Realize speaking behavior. Under certain circumstances the conventional heating systems even completely ver to be waived. In the medium circuit one can continue Thermostatic valve can be arranged, which a con constant medium temperature guaranteed.
Bei einem erfindungsgemäßen Verfahren zur Abschirmung von in Kraftfahrzeugen von zumindest bereichsweise von Abschirmelementen umgebenen Wärmequellen abgege bene Wärme wird durch das Abschirmelementinnere ein fluides Medium geführt, das mit einem der Wärmequelle zugewandten Bereich des Abschirmelementes in Kontakt gebracht und dadurch erwärmt wird.
