Abstract
Description
Die Erfindung betrifft einen Luftführungskanal mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention relates to an air duct with the features of the preamble of patent claim 1.
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, in particular for instrument panels, become common as a module with welded on Made hat profiles. The module created by this serves on the one hand as an air duct from the air conditioner to the air outlets in the instrument panel and on the other side it is simultaneous a stiffening 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.Strength Sunlight in summer, passing through the windshield directly on the instrument panel and thus on the upper part of the air duct so can the cold air from the air conditioning in the air duct heat before the vents reached. Conversely, cooling the cold air from the air conditioner the surface of the instrument panel, whereby it is at high humidities for condensation in the Air duct and / or on the dashboard top can come. Both effects are not wanted. Cool in winter on the first kilometers the still cold interior air the instrument panel and thus the air conditioner heated Air in the underlying air duct before the vents and So that the occupants or the windshield for dehumidification or Defrosting achieved. 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 are the surfaces these air ducts very reverberant, at unfavorable Material choice, the flow noise is so over the Instrument panel body even stronger.
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.was standing The technology in automotive engineering is the instrument panel body and the hat profile over one Friction welding to connect with each other. Through this continuous welding can be easy Errors arise that are not detected. It thus arises undesirable Leaks and if through these small, fine leaks Air from the air duct exit, additional disturbing noise sources.
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, at the described thermal disadvantages and disturbing flow noise at least be 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.Especially if one according to claim 14 from the otherwise original here friction welding its disadvantages (leaks, high costs) become practical without additional Expenditure and avoided without taking into account other disadvantages.
Die Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausführungen beschreiben die Unteransprüche.The Task is according to the invention with the features of claim 1. Advantageous versions describe the subclaims.
In der Zeichnung sind der Stand der Technik und verschiedene, bevorzugte Ausführungsbeispiele der Erfindung dargestellt. Es zeigen:In The drawings are the prior art and various, preferred Embodiments of the Invention shown. Show it:
In
Im
Sommer scheinen die Sonnenstrahlen
- 1. Durch die Sonnenstrahlen
8 und die daraus resultierende warme Instrumententafel4 erwärmt sich die kalte (gekühlte) Luft, die aus dem Klimagerät durch den Luftführungskanal3 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 Sonne liegende Instrumententafel4 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 der Instrumententafelwand5 und dem Hutprofil6 beim Stand der Technik in der Regel Verscheißungen 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 resulting warm instrument panel4 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 the sun instrument panel4 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 the instrument panel wall5 and the hat profile6 In the prior art are usually Verscheißungen, in particular friction welding, which can lead to the disadvantages already described as leaks and thus to additional disturbing noise sources.
