Vorrichtung zur Abscheidung von Wasser aus der einer Brennkraftmaschine zuzuführenden Verbrennungsluft Device for separating water from the combustion air to be supplied to an internal combustion engine
Technisches Gebiet Technical area
Die Erfindung bezieht sich auf eine Vorrichtung zur Abscheidung von Wasser aus der einer Brennkraftmaschine zuzuführenden Verbrennungsluft nach dem Oberbegriff des Anspruches 1 . The invention relates to a device for separating water from the combustion air to be supplied to an internal combustion engine according to the preamble of claim 1.
Stand der Technik State of the art
In der DE 198 55 992 A1 wird ein Wasserabscheider beschrieben, der dazu dient, Wasser aus einem Luftstrom in einem Strömungskanal abzuscheiden, welcher einer Brennkraftmaschine zugeführt wird. Der Wasserabscheider weist in einem Gehäuse eine Mehrzahl parallel verlaufender Abscheidelamellen auf, zwischen denen Strömungskanäle gebildet sind. Zur Umlenkung des Luftstroms weisen die Abscheidelamellen einen parallel versetzten Abschnitt auf, so dass die heranströmende, mit Feuchtigkeit belade- ne Luft unter einem Winkel auf die Lamellenwand auftrifft und Wassertröpfchen sich an der Wand anlagern können. Das abgeschiedene Wasser wird über einen Sammelkanal im unteren Bereich des Wasserabscheiders ausgetragen. In DE 198 55 992 A1, a water separator is described, which serves to separate water from an air stream in a flow channel, which is supplied to an internal combustion engine. The water separator has in a housing a plurality of parallel Abscheidellamellen between which flow channels are formed. In order to redirect the air flow, the separator lamellae have a section offset in parallel, so that the inflowing, moisture-laden air impinges on the lamella wall at an angle and water droplets can accumulate on the wall. The separated water is discharged via a collecting channel in the lower part of the water separator.
Offenbarung der Erfindung Der Erfindung liegt die Aufgabe zugrunde, mit einfachen konstruktiven Maßnahmen eine Vorrichtung zur Abscheidung von Wasser aus der einer Brennkraftmaschine zuzuführenden Luft effizient auszuführen. DISCLOSURE OF THE INVENTION The object of the invention is to carry out, with simple design measures, a device for separating water from the air to be supplied to an internal combustion engine efficiently.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an. This object is achieved with the features of claim 1. The dependent claims indicate expedient developments.
Bei der erfindungsgemäßen Vorrichtung handelt es sich um eine Lufteintrittsvorrichtung, über die einer Brennkraftmaschine in einem Fahrzeug Verbrennungsluft zugeführt wird und die dazu ausgelegt ist, Wasser, welches in der heranströmenden Luft mitgeführt wird, abzuscheiden. Hierfür weist die Vorrichtung in einem Gehäuse eine Mehrzahl paralleler Abscheidelamellen auf, zwischen denen Strömungskanäle für die Luft gebildet sind. Des Weiteren ist vorgesehen, dass die Abscheidelamellen unter einem Anstell- bzw. Öffnungswinkel im Gehäuse gehalten sind. Der Anstell- bzw. Öffnungswinkel legt die Größe der Öffnung zwischen benachbarten Abscheidelamellen und damit den Querschnitt der zwischen benachbarten Abscheidelamellen verlaufenden Strömungskanäle fest. Aufgrund des Anstell- bzw. Öffnungswinkels ist die Lamellenoberfläche der heranströmenden Luft zugewandt, so dass die Abscheidung an den Lamellen verbessert ist. Der Anstell- bzw. Öffnungswinkel bezieht sich auf die Gehäuseebene, in der die Abscheidelamellen gelagert bzw. gehalten sind. Bei aufrechter Anordnung der Vorrichtung fällt die Gehäuseebene mit einer Vertikalebene zusammen, in der auch die vertikale bzw. Lotrechte liegt, gegenüber der die Abscheidelamellen unter dem Neigungswin- kel angeordnet sind. Die Abscheidelamellen sind unter einem Anstell- bzw. Öffnungswinkel gehalten und fallen an der Anströmseite nach außen ab, so dass heranströmende Luft zwischen benachbarten Abscheidelamellen unter dem Anstellbzw. Öffnungswinkel nach oben strömen muss. An den Lamellen abgeschiedene Wassertröpfchen fließen zum Teil unmittelbar über die Lamellenoberfläche ab, wodurch der Abscheidegrad verbessert ist. The device according to the invention is an air inlet device, via which combustion air is supplied to an internal combustion engine in a vehicle and which is designed to carry water, which is carried along in the approaching air is going to leave. For this purpose, the device has in a housing a plurality of parallel Abscheidelamellen, between which flow channels for the air are formed. Furthermore, it is provided that the Abscheidellamellen are held at a pitch or opening angle in the housing. The Anstell- or opening angle determines the size of the opening between adjacent Abscheidelamellen and thus the cross section of the running between adjacent Abscheidellamellen flow channels. Due to the Anstell- or opening angle, the fin surface of the inflowing air faces, so that the deposition is improved at the fins. The pitch or opening angle refers to the housing level in which the Abscheidellamellen are stored or held. When the device is arranged upright, the housing plane coincides with a vertical plane in which the vertical or perpendicular is located, with respect to which the separation lamellae are arranged below the angle of inclination. The Abscheidelamellen are kept at a pitch or opening angle and fall on the upstream side to the outside, so that inflowing air between adjacent Abscheidellamellen under the Anstellbzw. Opening angle must flow upwards. Water droplets deposited on the lamellae partly flow directly over the lamellar surface, which improves the separation efficiency.
Die Abscheidelamellen sind vorzugsweise schräg im Gehäuse angeordnet und schließen gegenüber der Lotrechten bzw. Vertikalen einen Neigungswinkel ein, so dass Wasser, welches an den Abscheidelamellen sich anlagert, durch die Schrägstellung abflie- ßen kann. The Abscheidelamellen are preferably arranged obliquely in the housing and include an angle of inclination relative to the vertical or vertical, so that water, which attaches to the Abscheidelamellen, can flow through the inclined position Shen.
Die Abscheidelamellen weisen somit eine doppelte Neigung bzw. Schrägstellung auf, und zwar zum einen die Schrägstellung mit dem Neigungswinkel gegenüber der Vertikalen und zum andern der Anstell- bzw. Öffnungswinkel gegenüber der Gehäuseebene. Beide Winkel unterstützen die Abscheidung, wobei der Anstell- bzw. Öffnungswinkel die Aufprallfläche für die herangeführte, mit Feuchtigkeit beladene Verbrennungsluft vergrößert und der Neigungswinkel die Ableitung des abgeschiedenen Wassers von den Abscheidelamellen unterstützt. Grundsätzlich möglich ist auch eine Ausführung mit senkrecht oder waagrecht stehenden Abscheidelamellen, also mit einem Neigungswinkel gleich 0° bzw. 90°. The Abscheidelamellen thus have a double inclination or inclination, on the one hand, the inclination with the inclination angle relative to the vertical and on the other hand, the pitch or opening angle relative to the housing level. Both angles support the deposition, wherein the Anstell- or opening angle increases the impact surface for zoom introduced, laden with moisture combustion air and the angle of inclination supports the discharge of the separated water from the Abscheidelamellen. In principle, a version with vertical or horizontal standing Abscheidellamellen, ie with an inclination angle equal to 0 ° or 90 °.
Die Abscheidelamellen sind zweckmäßigerweise als in sich ebene Platten ausgeführt. Derartige Abscheidelamellen lassen sich zum einen leicht herstellen und in das Gehäuse montieren, zum andern ist der Strömungswiderstand für die herangeführte Luft nicht durch Umlenkungen erhöht. The Abscheidellamellen are expediently designed as in itself flat plates. Such Abscheidellamellen can be easily manufactured and mounted in the housing, on the other hand, the flow resistance for the zoomed-in air is not increased by deflections.
Es kann gegebenenfalls zweckmäßig sein, die Anströmfläche der Abscheidelamellen gewölbt auszuführen, um das Abtropfen des abgeschiedenen Wassers zu verbessern. Grundsätzlich genügt aber auch eine ebene Anströmfläche. If appropriate, it may be expedient to make the inflow surface of the separation louvers curved in order to improve the dripping off of the separated water. In principle, however, a flat inflow area is sufficient.
Gemäß einer weiteren zweckmäßigen Ausführung ist vorgesehen, dass der Anstellbzw. Öffnungswinkel der Abscheidelamellen veränderlich einstellbar ist. Die Abscheidelamellen sind zu diesem Zweck schwenkbeweglich im Gehäuse gelagert, so dass der Anstell- bzw. Öffnungswinkel bei einer Betätigung um die Schwenkachse verändert wird. Die Einstellung des Anstell- bzw. Öffnungswinkels erfolgt zweckmäßigerweise mithilfe eines Aktuators, beispielsweise ein elektromagnetisches Stellglied, das die Abscheidelamellen um die Schwenkachse zum Erreichen des gewünschten Anstell- bzw. Öffnungswinkels verstellt. According to a further advantageous embodiment, it is provided that the Anstellbzw. Opening angle of Abscheidelamellen is variably adjustable. The Abscheidelamellen are pivotally mounted in the housing for this purpose, so that the pitch or opening angle is changed by an actuation about the pivot axis. The adjustment of the setting or opening angle is expediently carried out with the aid of an actuator, for example an electromagnetic actuator, which adjusts the separating lamellae about the pivot axis in order to achieve the desired setting or opening angle.
Zweckmäßigerweise sind sämtliche Abscheidelamellen im Gehäuse mit dem gleichen Neigungswinkel versehen, der bezogen auf die Vertikale insbesondere in einem Winkelbereich zwischen 30° und 60° liegt und vorzugsweise zumindest annähernd 45° be- trägt. Auch der Anstell- bzw. Öffnungswinkel kann in einem Winkelbereich zwischen 30° und 60° liegen. Die Abscheidelamellen können alle den gleichen Anstell- bzw. Öffnungswinkel aufweisen, wobei grundsätzlich auch Ausführungen in Betracht kommen, in denen zumindest ein Teil der Abscheidelamellen einen unterschiedlichen Anstellbzw. Öffnungswinkel aufweisen. Beispielsweise ist es möglich, dass sich der Anstell- bzw. Öffnungswinkel über die Höhe der Vorrichtung gesehen verändert, insbesondere in der Weise, dass der Anstell- bzw. Öffnungswinkel im oberen Bereich der Vorrichtung größer ist als im unteren Bereich. Dies kann zur Vergleichmäßigung der Strömungsgeschwindigkeit über dem Querschnitt führen. Gemäß einer weiteren zweckmäßigen Ausführung sind Wasserableitungsrinnen an den Abscheidelamellen vorgesehen, die sich parallel zur Längserstreckung der Abscheidelamellen erstrecken und dazu dienen, abgeschiedenes Wasser abzuleiten. Die Wasserableitungsrinnen sorgen für ein sicheres Abführen abgeschiedener Wassertröpfchen und verhindern, dass bereits abgeschiedene Wassertröpfchen wieder vom Luftstrom mitgerissen und in Richtung der Brennkraftmaschine geführt werden. Die Wasserableitungsrinnen liegen vorzugsweise benachbart zu dem in Strömungsrichtung der Luft hinteren Rand der Abscheidelamellen und sind beispielsweise als halboffene Rinnen ausgebildet, die sich über die Oberseite der Abscheidelamellen erheben. Die Oberseite der Abscheidelamellen bildet die Aufprallfläche, an der das Wasser abgeschieden wird. Durch den Luftstrom gelangt das abgeschiedene Wasser über die Oberseite der Lamellen zu den hinten liegenden Wasserableitungsrinnen und wird in diesen seitlich abgeleitet. Aufgrund der Schrägstellung der Abscheidelamellen im Gehäuse stehen auch die Wasserableitungsrinnen unter dem gleichen Neigungswinkel wie die Abscheidelamellen, was den Vorteil hat, dass das Wasser in den Rinnen durch seine Gewichtskraft abströmt. Appropriately, all Abscheidelamellen are provided in the housing with the same angle of inclination, which is relative to the vertical, in particular in an angular range between 30 ° and 60 °, and preferably at least approximately 45 °. The setting or opening angle can be in an angular range between 30 ° and 60 °. The Abscheidelamellen can all have the same Anstell- or opening angle, with in principle also come into consideration, in which at least a portion of the Abscheidellamellen a different Anstellbzw. Have opening angle. For example, it is possible for the setting or opening angle to change over the height of the device, in particular in such a way that the setting or opening angle in the upper region of the device is greater than in the lower region. This can lead to equalization of the flow velocity over the cross section. According to a further expedient embodiment, drainage channels are provided on the separation blades which extend parallel to the longitudinal extension of the separation blades and serve to drain off separated water. The water discharge channels ensure safe removal of separated water droplets and prevent entrained water droplets are again entrained by the air flow and guided in the direction of the internal combustion engine. The water drainage channels are preferably adjacent to the rear edge of the separation fins in the flow direction of the air and are formed, for example, as half-open channels which rise above the top of the separation fins. The top of the separator louvers forms the impact surface on which the water is separated. Through the air flow, the separated water passes over the top of the slats to the rear water discharge channels and is discharged laterally in these. Due to the inclination of the Abscheidellamellen in the housing and the drainage channels are at the same inclination angle as the Abscheidellamellen, which has the advantage that the water flows through the gutters by its weight.
Gemäß weiterer zweckmäßiger Ausführung ist am Gehäuse seitlich benachbart zu den Abscheidelamellen ein zumindest im Wesentlichen vertikal verlaufender Wasserablei- tungskanal angeordnet. Diesem Wasserableitungskanal wird das Wasser von den Wasserableitungsrinnen an den Abscheidelamellen zugeführt. Das stirnseitige Ende der Wasserableitungsrinnen mündet in den vertikalen Wasserableitungskanal bzw. liegt in unmittelbarer Nachbarschaft zum Wasserableitungskanal. Somit ergibt sich ein Strömungsweg der an der Oberfläche der Wasserabscheidelamellen abgeschiedenen Wassertröpfchen hin zu der Wasserableitungsrinne, entlang dieser zum Wasserableitungskanal und schließlich entlang des Wasserableitungskanals bis zum Verlassen des Gehäuses der Vorrichtung. According to a further expedient embodiment, an at least substantially vertically extending water discharge duct is arranged on the housing laterally adjacent to the separation louvers. This water discharge channel, the water is supplied from the water discharge channels to the Abscheidellamellen. The front end of the water discharge channels opens into the vertical water outlet channel or is in the immediate vicinity of the water discharge channel. Thus, there is a flow path of the water droplets deposited on the surface of the water separation fins toward the water drainage channel, along this to the water drainage channel, and finally along the water drainage channel until it leaves the housing of the device.
Da starker Fahrtwind das Wasser in der Wasserableitungsrinne gegebenenfalls nach oben treiben kann, ist es zweckmäßig, sowohl am unteren Ende als auch am oberen Ende der Wasserableitungsrinne jeweils einen zumindest im Wesentlichen vertikal verlaufenden Wasserableitungskanal vorzusehen. Kurze Beschreibung der Zeichnungen Since strong wind can possibly drive the water in the water discharge channel upwards, it is expedient to provide both at the lower end and at the upper end of the water discharge channel each having an at least substantially vertically extending water discharge channel.

In den Figuren ist eine Lufteintrittsvorrichtung 1 dargestellt, über die Umgebungsluft in einen Ansaugtrakt einer Brennkraftmaschine geführt wird. Die Lufteintrittsvorrichtung 1 befindet sich an einem Fahrzeug, beispielsweise im seitlichen Bereich eines Nutzfahrzeugs. Die Fahrtrichtung ist mit„F" gekennzeichnet. Die Lufteintrittsvorrichtung 1 weist in einem Gehäuse 2 eine Mehrzahl übereinander angeordneter Abscheidelamellen 3 auf, zwischen denen Strömungskanäle für das Heranführen der Verbrennungsluft gebildet sind. Teil des Gehäuses 2 ist ein rechteckiger Rahmen 4, in welchem die Abscheidelamellen 3 gelagert sind. Die Abscheidelamellen weisen, wie Fig. 2 zu entnehmen, gegenüber einer Vertikalen bzw. Lotrechten, die mit dem Gewichtskraftsvektor übereinstimmt, einen Neigungswinkel α auf, der in einem Winkelbereich zwischen 30° und 60° liegt und insbesondere zumindest annähernd 45° beträgt. Zweckmäßigerweise besitzen sämtliche Abscheidelamellen 3 innerhalb des Rahmens 4 des Gehäuses 2 den gleichen Neigungswinkel a. In the figures, an air inlet device 1 is shown, is passed through the ambient air in an intake tract of an internal combustion engine. The air inlet device 1 is located on a vehicle, for example in the lateral area of a commercial vehicle. The direction of travel is marked "F." The air inlet device 1 has a plurality of deposition louvers 3 arranged one above the other in a housing 2, between which flow channels for bringing the combustion air in. Part of the housing 2 is a rectangular frame 4, in which the separation louvers 3, the separation lamellae, as shown in FIG. 2, have an angle of inclination α, which lies in an angular range between 30 ° and 60 ° and, in particular, at least approximately 45 °, with respect to a vertical or perpendicular which coincides with the weight force vector Appropriately have all Abscheidelamellen 3 within the frame 4 of the housing 2, the same inclination angle a.
Wie Fig. 3 zu entnehmen, sind die Abscheidelamellen 3 zusätzlich unter einem Anstell- bzw. Öffnungswinkel ß im Rahmen 4 des Gehäuses 2 gehalten und fallen an der Anströmseite nach außen ab. Der Anstell- bzw. Öffnungswinkel ß bezieht sich auf die Ebene 6 des Rahmens 4 des Gehäuses 2, in welchem die Abscheidelamellen 3 aufgenommen sind. Bei aufrechter Anordnung der Lufteintrittsvorrichtung 1 , so wie dies in den Figuren dargestellt ist, liegt die Vertikale 5 in der Ebene 6 bzw. parallel zur Ebene 6. Der umlaufende Rahmen 4 weist Längsseiten auf, die zumindest annähernd parallel zur Vertikalen 5 liegen. Wie Fig. 2 zu entnehmen, kann der Rahmen 4 aber geringfügig gebogene Seiten besitzen Längsseiten besitzen und somit von der Vertikalen 5 abweichen. Der Neigungswinkel a, unter dem die Abscheidelamellen im Gehäuse gehalten sind, ist fest vorgegeben und kann nicht verändert werden. Der Anstell- bzw. Öffnungswinkel ß kann dagegen gegebenenfalls einstellbar ausgeführt sein, indem die Abscheidelamellen entlang einer Achse verschwenkbar sind, die parallel zur Lamellenlängsachse verläuft. Zum Einstellen des gewünschten Anstell- bzw. Öffnungswinkels ß können Aktuatoren vorgesehen sein, wobei gegebenenfalls ein gemeinsamer Aktuator für die gemeinsame Einstellung des Öffnungs- bzw. Anstellwinkels sämtlicher Abscheidelamellen ausreichend ist. As can be seen from FIG. 3, the separating lamellae 3 are additionally held at a setting or opening angle β in the frame 4 of the housing 2 and drop off on the inflow side to the outside. The setting or opening angle ß refers to the plane 6 of the frame 4 of the housing 2, in which the Abscheidelamellen 3 are added. In an upright arrangement of the air inlet device 1, as shown in the figures, the vertical 5 lies in the plane 6 or parallel to the plane 6. The peripheral frame 4 has longitudinal sides which are at least approximately parallel to the vertical 5. As can be seen from FIG. 2, however, the frame 4 may have slightly curved sides and may have longitudinal sides and thus deviate from the vertical 5. The inclination angle a, under which the Abscheidellamellen are held in the housing is fixed and can not be changed. The setting or opening angle ß, however, may optionally be made adjustable by the Abscheidelamellen are pivotable along an axis which is parallel to the lamella longitudinal axis. For setting the desired setting or opening angle ß actuators may be provided, wherein optionally a common actuator for the common adjustment of the opening or angle of attack of all Abscheidellamellen is sufficient.
Die Oberseite 8 (Fig. 3, 4) der Abscheidelamellen 3 bildet die Anströmfläche und ist dem herangeführten Luftstrom zugewandt. Die im Luftstrom enthaltenen Wasserpartikel werden an der Oberseite 8 der Abscheidelamellen abgeschieden. Für eine geordnete Strömungsführung ist an dem in Strömungsrichtung hinteren Rand der Abscheidelamellen jeweils eine Wasserableitungsrinne 7 angeordnet, die als halboffene und sich über die Oberseite der Abscheidelamellen erhebende Rinne ausgebildet ist. Die Wasser-ableitungsrinne 7 ist einteilig mit der jeweiligen Abscheidelamelle ausgeführt. The upper side 8 (FIGS. 3, 4) of the separation lamellae 3 forms the inflow surface and faces the supplied air flow. The water particles contained in the air stream are deposited on the upper side 8 of the Abscheidellamellen. For an orderly flow guidance, in each case a water discharge channel 7, which is designed as a half-open channel rising above the top of the separation slats, is arranged on the rear edge of the separation slats in the direction of flow. The water-discharge channel 7 is made in one piece with the respective Abscheidelamelle.
Der Wasserströmungsverlauf ist in Fig. 4 eingezeichnet. Zunächst trifft die herangeführte Luft mit den darin enthaltenen Wasserpartikeln auf die Oberseite 8 der Abscheidelamellen 3 auf und wird dort abgeschieden. Durch den Luftstrom wandern die Wasserpartikel, wie mit der Pfeilrichtung angegeben, zu der Wasserableitungsrinne 7 und können in dieser aufgrund der Schrägstellung der Abscheidelamellen seitlich bzw. schräg nach unten abströmen. In der zugewandten Längsseite des Rahmens 4 des Gehäuses 2 befindet sich ein Wasserableitungskanal 10, der vertikal verläuft und in den die Wasserableitungsrinnen 9 einmünden. Das in der Wasserableitungsrinne 7 entlangfließende Wasser gelangt somit in den vertikalen Ableitungskanal 10 und kann beispielsweise über eine Abströmöffnung 9 aus dem Gehäuse in die Umgebung abgeleitet werden. The water flow profile is shown in Fig. 4. First, the supplied air with the water particles contained therein on the top 8 of the Abscheidellamellen 3 and is deposited there. Due to the air flow, the water particles migrate, as indicated by the arrow direction, to the water discharge channel 7 and can flow off laterally or obliquely downwardly there due to the inclination of the separation slats. In the facing longitudinal side of the frame 4 of the housing 2 there is a water discharge channel 10 which extends vertically and into which the water discharge channels 9 open. The water flowing along in the water discharge channel 7 thus enters the vertical discharge channel 10 and can be discharged from the housing into the environment, for example via an outflow opening 9.
Um auch im Falle starken Fahrtwinds, der das Wasser in der Wasserableitungsrinne 7 gegen die Schrägstellung nach oben treiben kann, für einen Wasserablauf zu sorgen, ist es zweckmäßig, nicht nur am unteren Ende, sondern auch am oberen Ende der Wasserableitungsrinne 7 einen zumindest im Wesentlichen vertikal verlaufenden Was- serableitungskanal vorzusehen. In order to ensure a drainage even in the case of strong wind, which can drive the water in the water drainage channel 7 against the inclination, it is expedient not only at the lower end, but also at the upper end of the water drainage channel 7 at least substantially vertically extending water drainage channel.
