Offenbarung der ErfindungDisclosure of the invention
Aufgabe der Erfindung ist es, ein Filterelement zu schaffen, mit dem ein unsachgemäßer Einbau in einem Filtergehäuse ausgeschlossen ist. Diese Aufgabe wird durch ein Filterelement mit den Merkmalen des Anspruches 1 gelöst.task The invention is to provide a filter element, with a improper installation in a filter housing is excluded. This task is accomplished by a filter element the features of claim 1 solved.
Durch den symmetrischen Aufbau des zumindest dreischichtigen Filterlagenverbundes, welcher durch die beiden baugleichen Außenfilterlagen zwei voneinander unabhängige Anströmflächen bildet, ist eine Verbundgeometrie gegeben, die sich durch ihre zweifache Einbaulage auszeichnet. Folglich kann das mehrschichtige, sandwichartig aufgebaute Filterelement in einer ersten Einbaulage mit seiner ersten Filterschicht hin zum Anströmkanal oder in gleichwirkender Weise in einer zweiten Einbaulage mit seiner gegenüberliegenden Filterschicht hin zum Anströmkanal in einem Filtergehäuse untergebracht werden. Ein unsachgemäßes Einsetzen des Filterelementes in das Gehäuse kann vermieden werden, da das Filterelement zwangsläufig und unabhängig von seiner Lage im Filtergehäuse formgenau in seine bestimmungsgemäße Einbauposition gebracht wird. Da die Anströmrichtung des Filterelementes mit seinem symmetrischen Filtermedienaufbau und damit mit zwei gleichwirkenden Anströmflächen eine untergeordnete Rolle spielt, können in beiden Durchströmungsrichtungen die geforderten Leistungsdaten erfüllt werden. Auf beiden Anströmseiten liegt somit eine gleichgroße Partikelspeicherkapazität mit einem entsprechenden Anfangsabscheidegrad vor. Kostenintensive und technisch aufwendige Codiermaßnahmen, wie beispielsweise Schlüssel-Schloss-Systeme oder auch so genannte POKA-YOKE-Vorkehrungen, die einen unsachgemäßen Einbau des Filterelementes in dem Filtergehäuse verhindern sollen, sind infolgedessen entbehrlich.By the symmetrical structure of the at least three-layer filter layer composite, which two by the two identical outer filter layers independent Forms inflow surfaces, is given a composite geometry, characterized by its twofold Installation position distinguishes. Consequently, the multilayer can be sandwiched constructed filter element in a first installation position with its first Filter layer towards the inflow channel or in the same manner in a second installation position with his opposite Filter layer towards the inflow channel in a filter housing be housed. An improper insertion of the filter element in the case can be avoided, since the filter element inevitably and independently from its location in the filter housing accurately brought into its intended installation position becomes. As the direction of flow the filter element with its symmetrical filter media construction and thus with two equally acting flow surfaces a minor role plays, can in both directions of flow the required performance data are met. Located on both upstream sides thus an equal size particle storage with a corresponding initial separation efficiency. costly and technically complex coding measures, such as Key-lock systems or so-called POKA-YOKE arrangements, which are improper installation to prevent the filter element in the filter housing are as a result dispensable.
In einer vorteilhaften Ausführungsform ist an den unbedeckten Flächen der beiden äußeren Filterlagen jeweils eine weitere Lage, insbesondere eine Trägerlage oder auch Stützlage, flächig angeordnet, wodurch dem Medienverbund eine verbesserte Steifigkeit und dadurch eine erhöhte Standfestigkeit zukommen.In an advantageous embodiment is at the uncovered areas the two outer filter layers in each case a further layer, in particular a carrier layer or support layer, flat arranged, whereby the media composite improved rigidity and thereby an increased Stability come.
Mit Vorteil sind die beiden äußeren Filterlagen auch als Partikelvliese, insbesondere als Feinfaser-Spinn-Vliesstoffe, mit jeweils einer integrierten Träger- oder Stützlage je Vlies ausgeführt, so dass eine Vorabscheidung von groben Partikeln erfolgen kann.With Advantage are the two outer filter layers also as particle nonwovens, in particular as fine fiber spun nonwovens, each with an integrated carrier or support layer depending Fleece designed, so that a pre-separation of coarse particles can take place.
In einer weiteren Ausgestaltung der Erfindung sind die beiden äußeren Filterlagen jeweils mit ihrer zugehörigen Trägerlage, insbesondere mittels Ultraschallschweiß- oder Thermoschweißverfahren, verschweißt; hierdurch entsteht ein vorgefertigtes Halbzeug, welches als Verbundwerkstoff in den Fertigungsprozess eingebracht wird und somit eine Vereinfachung des gesamten Herstellungsprozesses bewirkt.In Another embodiment of the invention are the two outer filter layers each with their associated Support layer, in particular by means of ultrasonic welding or thermal welding, welded; hereby A prefabricated semi-finished product is produced, which is a composite material is introduced into the manufacturing process and thus a simplification the entire manufacturing process causes.
Eine Ausführungsform der Erfindung sieht vor, dass die mittlere Filterlage als Aktivkohlelage oder andere Adsorbentien (Zeolithe, Adsorberpolymere) ausgeführt ist, so dass neben der Vorabscheidung von Grobpartikeln, beispielsweise aus Luft, auch eine nachrangige Abscheidung von Feinpartikeln bzw. organischen Schadstoffen erfolgt.A embodiment the invention provides that the middle filter layer as activated carbon layer or other adsorbents (zeolites, adsorber polymers) are carried out, so that in addition to the pre-separation of coarse particles, for example from air, also a subordinate separation of fine particles or organic pollutants takes place.
Mit Vorteil sind die Partikel der Adsorbenslage mittels eines dreidimensionalen Klebstoffgeflechtes aus feinsten Klebstofffäden miteinander verklebt. Hierdurch kann einerseits durch das geringe Klebstoffvolumen ein möglichst kleiner Druckverlust zwischen der Rohseite und der Reinseite des Filterelementes gewährleistet werden. Andererseits ist eine ausreichend hohe Adhäsion zwischen dem Klebstoff und den Aktivkohlepartikeln gegeben, so dass eine stabile Schicht aus Aktivkohle entsteht, deren Partikel lagetreu gebunden sind.With Advantageous are the particles of the adsorbent layer by means of a three-dimensional Adhesive mesh made of the finest adhesive threads glued together. hereby On the one hand by the low adhesive volume as possible small pressure loss between the raw side and the clean side of the Ensures filter element become. On the other hand, a sufficiently high adhesion is between given the adhesive and the activated carbon particles, so that a stable Layer of activated carbon is formed, the particles of which are bound to the ground are.
In einer vorteilhaften Ausführungsform ist die mittlere Aktivkohlelage mit den beiden angrenzenden Filterlagen mittels Klebstoff verklebt, so dass auf einfache Weise und mit günstigen Mitteln eine dauerhafte und zuverlässige Verbindung geschaffen ist.In an advantageous embodiment is the middle activated carbon layer with the two adjacent filter layers glued by means of glue, so that in a simple way and with favorable Means a lasting and reliable connection created is.
Mit Vorteil weisen die Klebstofffäden einen Durchmesser von 10–150 µm auf, wodurch ein außerordentlich feines Klebstoffgeflecht erzielbar ist, welches eine hohe Bindungskraft zwischen den zu verbindenden Partikeln aufweist und lediglich einen kleinen Differenzdruck zwischen der Roh- und Reinseite des Filterelementes bedingt.With Advantage show the adhesive threads a diameter of 10-150 μm, which makes an extraordinary Fine adhesive mesh can be achieved, which has a high binding force between the particles to be joined and only a small Differential pressure between the raw and clean side of the filter element conditionally.
In einer weiteren Ausgestaltung dient en reaktives Klebstoffsystem, z. B. auf PU-Basis, mittels dem eine stabile Klebeverbindung in einem für den Automobilsektor relevanten Temperaturbereich von ca. –40°C bis ca. 100°C erreichbar ist.In a further embodiment, a reactive adhesive system, eg. B. based on PU, means which is a stable adhesive bond in a relevant for the automotive sector temperature range of about -40 ° C to about 100 ° C can be achieved.
Besonders vorteilhaft ist die Verwendung des Filterelementes als Luftfilter, insbesondere als Innenraumluftfilter, da durch den symmetrischen Filteraufbau eine gelegentlich vorkommende, unklare Einbausituation am Filtergehäuse im Fahrzeug unerheblich ist. Ein fehlerhafter Einsatz des Filterelementes in das Filtergehäuse, bei dem die Rohseite des Filterelementes der Reinseite des Filtergehäuses zugewandt ist und umgekehrt, kann somit ausgeschlossen werden.Especially advantageous is the use of the filter element as an air filter, in particular as cabin air filters, as by the symmetrical Filter construction an occasional, unclear installation situation on the filter housing is negligible in the vehicle. A faulty use of the filter element in the filter housing, in which the raw side of the filter element facing the clean side of the filter housing is and vice versa, can thus be excluded.
