Abstract
Luftführungskanal (3), der aus einem Flachprofil, insbesondere einer Instrumententafelwand (5), und einem Hutprofil (6) zusammengesetzt ist, dadurch gekennzeichnet, dass zwischen beiden eine Zwischenwand (11) aus thermisch und/oder akustisch isolierendem Material angeordnet ist.Air duct (3), which is composed of a flat profile, in particular an instrument panel wall (5), and a hat profile (6), characterized in that between the two an intermediate wall (11) made of thermally and / or acoustically insulating material is arranged.
Description
Die Erfindung betrifft einen Luftführungskanal mit den Merkmalen des Oberbegriffs des Patentanspruchs 1. The invention relates to an air duct with the features of the preamble of
Luftführungskanäle, insbesondere für Instrumententafeln, werden üblicherweise als Modul mit angeschweißten Hutprofilen gefertigt. Das Modul, das dadurch erzeugt wird, dient auf der einen Seite als Luftführung von dem Klimagerät zu den Luftauslässen in der Instrumententafel und auf der anderen Seite ist es gleichzeitig eine Versteifung für den gesamten Instrumententafelkörper. Air ducts, especially for instrument panels, are usually manufactured as a module with welded hat profiles. The module that is generated thereby serves on the one hand as an air guide from the air conditioner to the air outlets in the instrument panel and on the other hand, it is also a stiffener for the entire instrument panel body.
Starke Sonneneinstrahlung im Sommer, die durch die Windschutzscheibe direkt auf die Instrumententafel und damit auf den oberen Teil des Luftführungskanals trifft, kann so die kalte Luft aus der Klimaanlage im Luftführungskanal erwärmen bevor sie die Ausströmer erreicht. Umgekehrt kühlt die kalte Luft aus der Klimaanlage die Oberfläche der Instrumententafel, wodurch es bei hohen Luftfeuchtigkeiten zur Kondensatbildung im Luftführungskanal und/oder auf der Instrumententafeloberseite kommen kann. Beide Effekte sind nicht erwünscht. Im Winter kühlt auf den ersten Kilometern die noch kalte Innenraumluft die Instrumententafel und somit die vom Klimagerät erwärmte Luft in dem darunter liegenden Luftführungskanal bevor sie die Ausströmer und damit die Insassen oder die Windschutzscheibe zur Entfeuchtung beziehungsweise Defrostung erreicht. Auch dieser Effekt ist unerwünscht. Strong sunlight in the summer, which hits through the windshield directly on the instrument panel and thus on the upper part of the air duct, can thus heat the cold air from the air conditioning in the air duct before it reaches the vents. Conversely, the cold air from the air conditioning system cools the surface of the instrument panel, which can lead to condensation in the air duct and / or on the dashboard top at high humidities. Both effects are not wanted. In winter, the still cold interior air cools the dashboard and thus the air heated by the air conditioner in the underlying air duct before it reaches the vents and thus the occupants or the windshield for dehumidification or defrosting on the first kilometer. Again, this effect is undesirable.
Oft sind die Oberflächen dieser Luftführungen sehr schallhart, bei ungünstiger Materialwahl werden die Strömungsgeräusche so über den Instrumententafelkörper noch verstärkt. Often, the surfaces of these air ducts are very reverberant, with unfavorable choice of material, the flow noise is so enhanced on the instrument panel body.
Stand der Technik im Automobilbau ist es, den Instrumententafelkörper und das Hutprofil über eine Reibschweißung miteinander zu verbinden. Durch diese durchgehende Verschweißung können leicht Fehler entstehen, die nicht entdeckt werden. Es entstehen somit unerwünschte Undichtigkeiten und wenn durch diese kleinen, feinen Leckstellen Luft aus dem Luftführungskanal austritt, zusätzliche störende Geräuschquellen. The state of the art in automotive engineering is to connect the instrument panel body and the hat profile with one another via friction welding. This continuous welding can easily cause errors that are not detected. This results in unwanted leaks and if through these small, fine leaks air exits the air duct, additional disturbing noise sources.
Aus der
Es ist daher Aufgabe der Erfindung, einen Luftführungskanal zu schaffen, bei dem die beschriebenen thermischen Nachteile und störende Strömungsgeräusche zumindest weitgehend vermieden werden. It is therefore an object of the invention to provide an air duct, in which the described thermal disadvantages and disturbing flow noise are at least largely avoided.
Insbesondere wenn man gemäß Anspruch 14 von dem hier sonst ursprünglichen Reibschweißen abgeht, werden dessen Nachteile (Undichtigkeiten, hohe Kosten) praktisch ohne zusätzlichen Aufwand und ohne in Kaufnahme anderer Nachteile vermieden. In particular, if you go according to
Die Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausführungen beschreiben die Unteransprüche. The object is achieved with the features of
In der Zeichnung sind der Stand der Technik und verschiedene, bevorzugte Ausführungsbeispiele der Erfindung dargestellt. Es zeigen: In the drawing, the prior art and various preferred embodiments of the invention are shown. Show it:
In
Im Sommer scheinen die Sonnenstrahlen
- 1. Durch die
Sonnenstrahlen 8 und die daraus resultierendewarme Instrumententafel 4 erwärmt sich die kalte (gekühlte) Luft, die aus dem Klimagerät durch denLuftführungskanal 3 geleitet wird, bevor sie durch die Ausströmer in den Instrumentenraum gelangt. Die mit viel Energieaufwand von der Klimaanlage gekühlte Luft kühlt so in erster Linie die in der Sonneliegende Instrumententafel 4 und erst in der zweiten Linie über die aus den Ausströmern austretende Luft die Insassen des Fahrzeugs. - 2. Ein weiterer Nachteil ist, dass solche Luftführungen oft schallhart ausgeführt sind, denn bei ungünstiger Materialwahl werden die Strömungsgeräusche über den Schalttafelkörper noch verstärkt.
- 3. Der dritte Nachteil ist, dass diese
Befestigungsmittel 7 zwischen derInstrumententafelwand 5 und demHutprofil 6 beim Stand der Technik in der Regel Verschweißungen sind, insbesondere Reibschweißungen, was zu den schon beschriebenen Nachteilen wie Undichtigkeit und damit zu zusätzlichen störenden Geräuschquellen führen kann.
- 1. Through the sun's rays
8th and the resultingwarm instrument panel 4 The cold (cooled) air coming out of the air conditioner through the air duct heats up3 is passed before it passes through the vent in the instrument room. The cooled air with much energy from the air conditioning cooled so primarily the lying in thesun instrument panel 4 and only in the second line on the exiting from the vents air the occupants of the vehicle. - 2. Another disadvantage is that such air ducts are often made hard-sounding, because in unfavorable choice of material, the flow noise on the panel body are still amplified.
- 3. The third disadvantage is that these
fasteners 7 between theinstrument panel wall 5 and thehat profile 6 In the prior art are usually welding, in particular friction welding, which can lead to the disadvantages already described as leaks and thus to additional disturbing noise sources.
Alle drei beschriebenen Nachteile können üblicherweise nachträglich durch zusätzliche Abdichtmaßnahmen unterbunden werden. Zum Beispiel kann eine solche Abdichtmaßnahme eine von außen auf das Hutprofil aufgebrachte Dämmung

Der erfindungsgemäße Luftführungskanal schafft also eine preiswerte, bedarfsgerechte thermische und/oder akustische Dämmung/Dämpfung ohne Einbußen an seinen Strömungseigenschaften zu haben. The air duct according to the invention thus provides an inexpensive, needs-based thermal and / or acoustic insulation / damping without sacrificing its flow properties.
