Filter, insbesondere für eine Klimaanlage eines KraftfahrzeugesFilter, in particular for an air conditioning system of a motor vehicle
Die Erfindung betrifft ein Filter für die Adsorption von Geruchsund/pder Schadstoffen, insbesondere für eine Klimaanlage eines Kraftfahrzeuges, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a filter for the adsorption of odors and/or pollutants, in particular for an air conditioning system of a motor vehicle, according to the preamble of claim 1.
Aus der DE 38 39 352 ist ein Filter bekannt, wie es in heutigen KIimaanlagen
für Kraftfahrzeuge Verwendung findet. Dieses Filter weist mehrere Lagen eines offenporigen Polyurethanschaumes auf, dessen Poren
mit · einem Adsorptionsmittel, insbesondere Aktivkohle-Körnchen beladen sind. Die Lagen aus Polyurethanschaum sind in einem Rahmen
gehalten.
25DE 38 39 352 discloses a filter of the type used in modern air conditioning systems for motor vehicles. This filter has several layers of open-pored polyurethane foam, the pores of which are loaded with an adsorbent, in particular activated carbon granules. The layers of polyurethane foam are held in a frame.

Dieses Filter wird hergestellt, indem die einzelnen Lagen des Polyurethanschaums zunächst mit einem geeigneten Verfahren mit der Aktivkohle beladen werden, dann die Lagen auf die entsprechende Filtergröße geschnitten, zusammengelegt und in einem Rahmen eingebracht werden. Dieses Herstellungsverfahren mit seinen vielen Arbeitsschritten ist entsprechend kostenungünstig. Ein weiterer großer Nachteil ist, daß die Aktivkohle-Körnchen aus den Poren herausfallen können, da der Polyurethanschaum elastisch ist und die Porengröße sich bei mechanischer Belastung ändert. Damit dieThis filter is manufactured by first loading the individual layers of polyurethane foam with the activated carbon using a suitable process, then cutting the layers to the appropriate filter size, putting them together and placing them in a frame. This manufacturing process with its many work steps is therefore cost-effective. Another major disadvantage is that the activated carbon grains can fall out of the pores, as the polyurethane foam is elastic and the pore size changes under mechanical stress. In order for the

Aktivkohle dennoch nicht verloren geht, ist das aus mehreren Lagen Polyurethanschaum bestehende Filter in der Regel von einem strumpfartigen Material umgeben. Dann kann die Aktivkohle zwar nicht mehr aus dem Filter entweichen, sie ändert jedoch ihre Lage, so daß der Filter dann ungleichmäßig mit der Aktivkohle beladen ist. Dadurch ergibt sich eine schlechte und ungleichmäßige Beaufschlagung der Aktivkohle mit der zu reinigenden Luft.To ensure that the activated carbon is not lost, the filter, which consists of several layers of polyurethane foam, is usually surrounded by a stocking-like material. The activated carbon can then no longer escape from the filter, but it changes its position so that the filter is then unevenly loaded with the activated carbon. This results in poor and uneven exposure of the air to be cleaned to the activated carbon.
Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, ein verbessertes Filter bereitzustellen, das einfach herstellbar ist und bei dem eine gleichmäßige Beaufschlagung des Adsorptionsmittel mit der zu reinigenden Luft über die Lebensdauer des Filters gewährleistet ist.Based on this prior art, it is the object of the invention to provide an improved filter that is easy to manufacture and in which a uniform exposure of the adsorbent to the air to be cleaned is ensured over the service life of the filter.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein gattungsgemäßes Filter mit den kennzeichnenden Merkmalen des Anspruchs 1.This object is achieved according to the invention by a generic filter with the characterizing features of claim 1.
Wenn erfindungsgemäß der Träger für das Adsorptionsmittel aus einzelnen Wellrippen aus Metall, die in einem Rahmen gehalten sind, gebildet ist und das Adsorptionsmittel auf den Wellrippen haftend aufgebracht ist, kann dieses seine Lage nicht verändern. Das Adsorptionsmittel wird dann stets gleichmäßig mit der zu reinigenden Luft beaufschlagt, so daß an jeder Stelle des Filters über die Lebensdauer des Filters die Filterwirkung erhalten bleibt. Da die einzelnen auf den WeI!rippen haftenden Adsorptionsmittel-Körnchen besser und vollständiger von der Luft umströmt werden, als dies bei den bekannten aus Polyurethanschaum bestehenden Filtern möglich wäre, kann die Adsorptionswirkung des Adsorptionsmittels effektiver genutzt werden.If, according to the invention, the carrier for the adsorbent is made of individual corrugated metal fins held in a frame and the adsorbent is adhered to the corrugated fins, it cannot change its position. The adsorbent is then always evenly exposed to the air to be cleaned, so that the filter effect is maintained at every point on the filter over the life of the filter. Since the individual adsorbent grains adhering to the corrugated fins are better and more completely surrounded by air than would be possible with the known filters made of polyurethane foam, the adsorption effect of the adsorbent can be used more effectively.
Ein weiterer großer Vorteil des erfindungsgemäßen Filters ist, daß der Druckabfall durch den Filter erheblich geringer ist als bei den bekannten, aus Polyurethanschaum bestehenden Filtern.Another great advantage of the filter according to the invention is that the pressure drop through the filter is considerably lower than with the known filters made of polyurethane foam.

Damit möglichst viele Welirippen innerhalb des Rahmens Platz finden, sind benachbarte Wellrippen parallel verlaufend angeordnet. Bevorzugt sind die Wellrippen durch den Rahmen verspannt gehalten. Mit besonderem Vorteil kann dann das Adsorptionsmittel mit einem Klebemittel auf den Wellrippen festgeklebt sein, wobei mit dem Klebemittel vorteilhafterweise die Wellrippen untereinander und der Rahmen mit den Well rippen verbunden ist.To ensure that as many corrugated ribs as possible can fit within the frame, neighboring corrugated ribs are arranged in parallel. The corrugated ribs are preferably held in place by the frame. The adsorbent can then be particularly advantageously glued to the corrugated ribs using an adhesive, whereby the adhesive advantageously connects the corrugated ribs to one another and the frame to the corrugated ribs.
Besonders bevorzugte Abmessungen der Wellrippen sind Gegenstand des Anspruchs 6, wonach die Dicke einer Well rippe zwischen 0,05 und 0,1 mm beträgt und die Rippendichte des Filters < 70/dm ist. Dadurch ist gewährleistet, daß die durch das Filter hindurchströmende Luft einerseits optimal reinigbar ist und andererseits noch ausreichend offene Fläche vorhanden ist, daß der Druckabfall über das Filter in einem Luftkanal,, in dem der Filter angeordnet ist, klein bleibt.Particularly preferred dimensions of the corrugated fins are the subject of claim 6, according to which the thickness of a corrugated fin is between 0.05 and 0.1 mm and the fin density of the filter is < 70/dm. This ensures that the air flowing through the filter can be cleaned optimally on the one hand and that there is still sufficient open area on the other hand so that the pressure drop across the filter in an air duct in which the filter is arranged remains small.
Eine Korngröße des granulären Adsorptionsmaterials von etwa .0,6 mm ist vorteilhaft, denn dann sind die Zwischenräume innerhalb einer Well rippe optimal ausnutzbar.A grain size of the granular adsorption material of about .0.6 mm is advantageous because then the gaps within a corrugated fin can be optimally utilized.
Als Adsorptionssubstanz findet zweckmäßigerweise Aktivkohle Verwendung. Bei Aktivkohle handelt es sich um eine Adsorbersubstanz mit besonders großer innerer Oberfläche für die Adsorption von Geruchsstoffen. Activated carbon is used as an adsorption substance. Activated carbon is an adsorption substance with a particularly large internal surface for the adsorption of odorous substances.
Besonders bevorzugt bildet das Filter Teil einer Heizung, insbesondere einer PTC-Heizung, so daß durch Aufheizen des Filters und damit der Wellrippen, das Filter regenerierbar ist, da bei Erwärmung des Adsorptionsmittels, beispielsweise der Aktivkohle, die adsorbierten Stoffe wieder desorbierbar sind.Particularly preferably, the filter forms part of a heater, in particular a PTC heater, so that the filter can be regenerated by heating the filter and thus the corrugated fins, since when the adsorption agent, for example the activated carbon, is heated, the adsorbed substances can be desorbed again.
Im Folgenden wird die Erfindung anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung im einzelnen erläutert. In der

Ein in der Zeichnung dargestelltes Filter 10 weist einen Rahmen 12 und einen Träger 14 für ein Adsorptionsmittel 16 in granulärer Form, vorzugsweise Aktivkohle, auf. Der Träger 14 für das Adsorptionsmittel 16 ist gebildet aus einzelnen WeI!rippen 18, von denen in Fig. 1 drei andeutungsweise dargestellt und mit den Bezugszeichen .18, 18' und 18'' bezeichnet sind. Die Welirippen 18, 18', 18'' bestehen aus Metall und sind in dem Rahmen 12 verspannt gehalten. Dabei verlaufen benachbarte Wellrippen 18, 18', 18 " parallel zueinander.A filter 10 shown in the drawing has a frame 12 and a carrier 14 for an adsorbent 16 in granular form, preferably activated carbon. The carrier 14 for the adsorbent 16 is formed from individual corrugated ribs 18, three of which are shown in Fig. 1 and designated by the reference symbols 18, 18' and 18''. The corrugated ribs 18, 18', 18'' are made of metal and are held in place in the frame 12. Neighboring corrugated ribs 18, 18', 18" run parallel to one another.
Das in granulärer Form vorliegende Adsorptionsmittel ist haftend auf den Wellrippen aufgebracht, wie dies in Fig. 2 bereichsweise dargestellt ist. Bevorzugt besteht die Verbindung zwischen Adsorptionsmittel 16 und Wellrippen 18 aus einem Klebemittel, das zur Vereinfachung des Herstellungsverfahrens gleichzeitig dazu nutzbar ist, die Wellrippen untereinander und den Rahmen mit den Wellrippen miteinander zu verbinden, so daß ein stabiles Filter erhalten wird. Die Dicke der Wellrippen beträgt vorzugsweise zwischen 0,05 und 0,1 mm und die Rippendichte des Filters ist vorzugsweise < 70/dm. Die Korngröße des granulären Absorptionsmittels beträgt etwa 0,6 mm.The adsorbent in granular form is applied to the corrugated fins in an adhesive manner, as shown in some areas in Fig. 2. The connection between adsorbent 16 and corrugated fins 18 preferably consists of an adhesive which, in order to simplify the manufacturing process, can also be used to connect the corrugated fins to one another and the frame to the corrugated fins, so that a stable filter is obtained. The thickness of the corrugated fins is preferably between 0.05 and 0.1 mm and the fin density of the filter is preferably < 70/dm. The grain size of the granular absorbent is approximately 0.6 mm.
