Description

Vorrichtung zum Filtrieren von Öl Device for filtering oil
Die Erfindung betrifft eine Vorrichtung zum Filtrieren von Öl nach dem Oberbegriff des Hauptanspruchs.The invention relates to a device for filtering oil according to the preamble of the main claim.
Eine derartige Vorrichtung ist z.B. aus der DE PS 533 732 bekannt, bei der ein Olfilter mit Kühler für Brennkraftmaschinen derart ausgestaltet ist, daß durch ein doppelwandiges Gehäuse mit einer inneren, beliebige Filtriereinrichtungen enthaltenden Kammer, gereinigtes Öl in die zur Kühlung dienende Außenkammer übertritt.Such a device is e.g. Known from DE PS 533 732, in which an oil filter with cooler for internal combustion engines is designed such that cleaned oil passes into the outer chamber serving for cooling through a double-walled housing with an inner chamber containing any filtering devices.
Weiterhin ist eine derartige Vorrichtung bekannt aus der DE PS 1 020 831 , bei der eine Vorrichtung zur Aufbereitung von Öl und Kühlflüssigkeiten bei Brennkraftmaschinen, insbesondere von Schmieröl und Kühlwasser, unter Verwendung eines Ölfilters und eines Kühlflüssigkeitsfilters dargestellt wird, wobei das Gehäuse des Ölfilters mit einem von der Kühlflüssigkeit durchströmten Mantel umgeben ist.Furthermore, such a device is known from DE PS 1 020 831, in which a device for treating oil and cooling liquids in internal combustion engines, in particular lubricating oil and cooling water, is shown using an oil filter and a cooling liquid filter, the housing of the oil filter having a is surrounded by the coolant flowing through the jacket.
Des weiteren ist aus dem deutschen Gebrauchsmuster 93 18 635 ein Plattenwärmetauscher, insbesondere ein Ölkühlmittelkühler bekannt. Dieser besteht aus mehreren aufeinandergestapelten wannenförmigen Wärmetauscherplatten sowie Zu- und Ablaufleitungen für ein erstes Fluid und Zu- und Abfuhrleitungen für ein zweites Fluid, wobei zwischen den einzelnen Platten jeweils abwechselnd das zu kühlende Medium und das Kühlmedium hindurchgeführt werden. Solche Plattenwärmetauscher finden insbesondere Anwendung bei dem Kühlen von Öl einer Verbrennungskraftmaschine. Das Kühlmittel ist zweckmäßigerweise das Kühlwasser des Kühlwasserkreislaufs der Maschine. Will man derartige Baugruppen nun in modernen Kraftfahrzeugen oder anderen mit Verbrennungskraftmaschinen betriebenen Apparaturen einsetzen, so ist daran nachteilig, daß die bekannten Baugruppen über große Außenabmessungen verfügen sowie über ein entsprechend hohes Eigengewicht oder, daß die Konstruktion so aufwendig ist, daß sie aus Kostengründen unrealisierbar bleibt.Furthermore, a plate heat exchanger, in particular an oil coolant cooler, is known from German utility model 93 18 635. This consists of several stacked trough-shaped heat exchanger plates as well as inlet and outlet lines for a first fluid and inlet and outlet lines for a second fluid, the medium to be cooled and the cooling medium being passed alternately between the individual plates. Such plate heat exchangers are used in particular for cooling oil in an internal combustion engine. The coolant is expediently the cooling water of the cooling water circuit of the machine. If you now want to use such assemblies in modern motor vehicles or other apparatus operated with internal combustion engines, it is disadvantageous that the known assemblies have large external dimensions and a correspondingly high dead weight or that the construction is so complex that it remains unrealizable for cost reasons .
Es ist somit Aufgabe der Erfindung, eine Vorrichtung der eingangs genannten Art dahingehend zu verbessern, daß eine Vorrichtung entsteht, die einfacher zu fertigen und zu montieren, kleiner in den Abmessungen, leichter und billiger ist, bei stets sicherem Betrieb.It is therefore an object of the invention to improve a device of the type mentioned in such a way that a device is created which is easier to manufacture and assemble, smaller in size, lighter and cheaper, with always safe operation.
Diese Aufgabe wird ausgehend von dem Oberbegriff des Hauptanspruchs durch dessen kennzeichnende Merkmaie gelöst. Von Vorteil ist hierbei, daß sowohl die Herstellungskosten der einzelnen Funktionseinheiten als auch die Kosten der Endmontage reduziert werdenThis problem is solved on the basis of the preamble of the main claim by its characteristic features. The advantage here is that both the manufacturing costs of the individual functional units and the costs of final assembly are reduced
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß das Ölkühlergehäuse als Trägerkörper des Ölfilters wirkt, mittels diesem die Vorrichtung mit der Verbrennungskraftmaschine verbindbar ist. Dieser Trägerkörper gibt der Vorrichtung eine Struktur, die einerseits die Verbindung der Vorrichtung mit der Verbrennungskraftmaschine definiert als auch die Anordnung der einzelnen Bauteile der Vorrichtung zueinander. Hierbei nimmt der Tragkörper sowohl den Filter als auch den Kühler auf, was zu Kosteneinsparungen bei den Werkzeugkosten führt. Teilen sich sowohl der Kühler als auch der Filter Gehäuseteile, so reduzieren sich die Abmessungen der Vorrichtung, was sie leichter, kleiner und billiger macht, da sie zu einer einzigen Funktionseinheit zusammengefaßt sind.An advantageous development of the invention provides that the oil cooler housing acts as a carrier body of the oil filter, by means of which the device can be connected to the internal combustion engine. This carrier body gives the device a structure that defines the connection of the device to the internal combustion engine and the arrangement of the individual components of the device. Here, the support body houses both the filter and the cooler, which leads to cost savings in tool costs. If both the cooler and the filter share housing parts, the dimensions of the device are reduced, which makes it lighter, smaller and cheaper, since they are combined into a single functional unit.
In einer anderen vorteilhaften Weiterbildung ist vorgesehen, daß das Ölkühlergehäuse und das Gehäuse des Ölfilters ineinander steckbar ausgeführt sind, was zu Erleichterungen bei der Montage führt. Weiter kann man erfindungsgemäß vorsehen, daß der Ölkühlereinsatz steckbar ausgeführt ist, was ihn in einem bestehenden Gehäuse einsetzbar macht und weitere Kosten reduzieren hilft, ebenfalls ergeben sich weitere Montagevereinfachungen.In another advantageous development, it is provided that the oil cooler housing and the housing of the oil filter are designed such that they can be plugged into one another, which simplifies assembly. Furthermore, it can be provided according to the invention that the oil cooler insert is designed to be pluggable, which makes it usable in an existing housing and helps to reduce further costs.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß wenigstens ein Bauteil des Moduls aus Kunststoff besteht. Selbst die komplette Ausführung der Vorrichtung und seiner Bauteile aus Kunststoff ist denkbar, wobei die Ausrüstung des Kunststoffs in der Weise erfolgt, daß er insbesondere im Bereich des Kühlers wärmeleitend ist. Die Ausführung der Vorrichtung in Kunststoff führt zwangsläufig zu Kosteneinsparungen und Gewichtsreduzierungen sowie in der Folge zu einem niedrigeren Kraftstoffverbrauch der Verbrennungskraftmaschine im Betrieb, da es von Vorteil ist,, ein Teil derart auszugestalten, daß es mehrere Funktionen übernimmt, um so die Anzahl der benötigten Teile in einem Fahrzeug zu reduzieren.An advantageous development of the invention provides that at least one component of the module consists of plastic. Even the complete design of the device and its components made of plastic is conceivable, the plastic being equipped in such a way that it is thermally conductive, particularly in the area of the cooler. The design of the device in plastic inevitably leads to cost savings and weight reductions and, as a result, to lower fuel consumption of the internal combustion engine in operation, since it is advantageous to design a part in such a way that it takes over several functions, and thus the number of parts required to reduce in a vehicle.
Weiter kann man erfindungsgemäß vorsehen, daß der Kunststoff wärmeleitfähig ausgerüstet ist, was zu einer Leistungssteigerung des Kühlers führt.Furthermore, it can be provided according to the invention that the plastic is thermally conductive, which leads to an increase in performance of the cooler.
In einer anderen vorteilhaften Weiterbildung ist vorgesehen, daß der Ölkühler ein Gegenstromkühler ist, was zu optimalen Kühlergebnissen führt.Another advantageous further development provides that the oil cooler is a counterflow cooler, which leads to optimal cooling results.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß ein Medium vorgesehen ist, das gleichzeitig Filtrierwirkung aufweist und Wärme leitet und/oder Turbulenz erzeugt.An advantageous development of the invention provides that a medium is provided which at the same time has a filtering effect and conducts heat and / or generates turbulence.
Von Vorteil ist daran, daß der Kühler eine zusätzliche Filterfunktion für das zu kühlende Medium übernimmt, was die Filterleistung erhöht oder die Bauhöhe, bzw. das Gewicht weiter reduziert, es werden Kosten und Bauraum gespart. Alternativ ist das Filtermittel ein Metallvlies, welches sowohl eine Filterwirkung als auch eine Turbulenzwirkung aufweist. Insbesondere die Turbulenzwirkung ist für eine optimale Wärmeübertragung an das Kühlmedium erforderlich. Die gute Wärmeleitfähigkeit des Metalls ergibt eine gute Wärmeübertragung und eine wirksame Filtrierung des zu kühlenden Mediums. Eine alternative Ausgestaltung sieht vor, Kühler und Filtermittel nebeneinander anzuordnen. Dies hat den Vorteil eines besonders einfachen Aufbaus, da in ein bestehendes Kühlerelement lediglich in oder neben dem Filtermittel angebracht werden muß. Das Filtermittel kann auch aus gesintertem Kunststoffgranulat gebildet werden. Solches Kunststoffgranulat ist bezüglich seiner Porosität auf die geforderte Filterwirkung einstellbar. Außerdem kann das Kunststoffgranulat mit metallischen Inhaltsstoffen versehen werden, so daß auch hier eine gute Wärmeleitfähigkeit erzielbar ist.The advantage of this is that the cooler takes on an additional filter function for the medium to be cooled, which increases the filter performance or further reduces the overall height or weight, and costs and space are saved. Alternatively, the filter medium is a metal fleece, which has both a filter effect and a turbulence effect. In particular the turbulence effect is required for optimal heat transfer to the cooling medium. The good thermal conductivity of the metal results in good heat transfer and effective filtration of the medium to be cooled. An alternative embodiment provides for the cooler and filter means to be arranged next to one another. This has the advantage of a particularly simple construction, since an existing cooler element only has to be attached in or next to the filter medium. The filter medium can also be formed from sintered plastic granules. The porosity of such plastic granulate can be adjusted to the required filter effect. In addition, the plastic granulate can be provided with metallic ingredients, so that good thermal conductivity can also be achieved here.
Weiterbildungsgemäß ist die Vorrichtung seriell aufgebaut. Zwischen Olkuhleroleinlaß und dem Ölfilterauslaß befindet sich der Ölkühlereinsatz und das Filtermittel sowie evtl. erforderliche Abstandshalter. Sowohl der Ölkühlereinsatz als auch das Filtermittel sind jeweils einzelne Elemente, die z. B. in eine beliebige Höhe aufeinander stapelbar sind, so daß sowohl die Kapazität des Filters als auch die Kapazität des Kühlers an die Erfordernisse der jeweiligen Verbrennungskraftmaschine angepaßt werden kann.According to a further development, the device is constructed in series. The oil cooler insert and the filter medium as well as any necessary spacers are located between the oil cooler inlet and the oil filter outlet. Both the oil cooler insert and the filter medium are individual elements that, for. B. can be stacked at any height, so that both the capacity of the filter and the capacity of the cooler can be adapted to the requirements of the respective internal combustion engine.
Weiter kann man erfindungsgemäß vorsehen, daß die Abdichtung des Ölkühlereinsatzes im Ölkühlergehäuse mittels einem oder mehreren O-Ringen erfolgt, was die Abdichtung einerseits einfach und billig macht, andererseits wird sie, insbesondere, da lediglich die Stutzen geringen Durchmessers betroffen sind, besonders sicher.Furthermore, according to the invention, it can be provided that the oil cooler insert in the oil cooler housing is sealed by means of one or more O-rings, which on the one hand makes the seal simple and inexpensive, and on the other hand it becomes particularly secure, in particular since only the small diameter sockets are affected.
Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei der Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können, für die hier Schutz beansprucht wird.These and further features of preferred developments of the invention are evident from the claims and also from the description and the drawings, the individual features being implemented individually or in groups in the form of subcombinations in the embodiment of the invention and in other fields, and beneficial as well as for Protectable versions can be represented, for which protection is claimed here.

Wie in der Figur 1a dargestellt, besteht die Vorrichtung zum Filtrieren von Öl aus einem Ölkühler 1. Dieser Ölkühler besteht aus einem Ölkühlergehäuse 2, welches wiederum einen Ölkühlereinsatz 3 beinhaltet. Auf der der nicht extra dargestellten Verbrennungskraftmaschine zugewendeten Seite befindet sich ein Olkuhleroleinlaß 4, der mit von der Verbrennungskraftmaschine zur Verfügung gestelltem Roh-Öl versorgt wird. Dieses Roh-Öl durchströmt den Ölkühlereinsatz, wobei es auf diesem Weg einen Teil seiner Wärmeenergie abgibt. Nachdem das Roh-Öl den Ölkühlereinsatz durchströmt hat, gelangt es durch den Ölkühlerölauslaß 5 in den Bereich des Ölfilters 8. Der Olfilter 8 umfaßt ein Gehäuse 9 sowie einen Olfiltereinlaß 10, einen Ölfilterauslaß 11 und ein Filtermittel 17. Im Bereich des Ölkühlerauslasses 5 existiert ein mit diesem kommunizierender Olfiltereinlaß 10, durch welchen das gekühlte Roh-Öl in das Olfilter 8 gelangt. Im Gehäuse 9 des Ölfilters 8 trennt das Filtermittel 17 die Roh- von der Rein-Ölseite dichtend ab. Nachdem das Öl das Filtermittel 17 passiert hat und alle abzuscheidenden Rückstände an diesem zurückgelassen hat, verlässt das gereinigte Öl die Vorrichtung zum Filtrieren 12 durch den Ölfilterauslaß 11 , welcher mit der Verbrennungskraftmaschine kommuniziert, insbesondere mit deren Ölversorgungsleitungen, die hier nicht extra dargestellt sind. Das Kühlmittel des Ölkühlers 1 ,das dem Kühlmittelkreislauf der Verbrennungskraftmaschine entnommen ist und das zum Abtransport der Wärmeenergie des Öls dient, tritt mittels des Ölkühlerkühlmitteleinlaß 6 in diesen, bzw. in dessen Ölkühlereinsatz 3 ein. Im Ölkühler, bzw. dem Ölkühlereinsatz 3 erfolgt der Wärmeübergang im Gegenstrom. Nachdem das Kühlmittel die Wärmeenergie des Öls augenommen hat, verläßt es den Ölkühler, bzw. dessen Ölkühlereinsatz 3 über den Olkuhlerkühlmittelauslaß 7 und gelangt von dort aus zum Kühler der nicht dargestellten Verbrennungskraftmaschine. Die Abdichtung der kurzen Stutzen des Ölkühlerein- bzw. -auslasses 4,5 innerhalb der Vorrichtung zum Filtrieren 12 erfolgt mittels O-Ringen 13, die ein- bzw. auslaßseitig angebracht sind und im Ölkühlergehäuse 2 das Öl- von der Kühlmittelseite trennen. Die Verbindung von Ölkühlergehäuse 2 und dem Gehäuse 9 des Ölfilters erfolgt mitteis eines Gewindes, die Abdichtung mittels eines O-Rings 13. Die Verbindung der Vorrichtung zum Filtrieren 12 mit der Verbrennungskraftmaschine, die nicht dargestellt ist, erfolgt mittels Adapter 14, welcher wiederum von Schrauben 15 unterstütz wird. Die Abdichtung zwischen Adapter 14 und der Vorrichtung zum Filtrieren erfolgt mittels einer dazwischen angebrachten Flachdichtung 16.As shown in FIG. 1a, the device for filtering oil consists of an oil cooler 1. This oil cooler consists of an oil cooler housing 2, which in turn contains an oil cooler insert 3. On the side facing the internal combustion engine (not shown separately) there is an oil cooler inlet 4 which is supplied with crude oil made available by the internal combustion engine. This crude oil flows through the oil cooler insert, releasing part of its thermal energy in this way. After the crude oil has flowed through the oil cooler insert, it passes through the oil cooler oil outlet 5 into the area of the oil filter 8. The oil filter 8 comprises a housing 9 and an oil filter inlet 10, an oil filter outlet 11 and a filter medium 17. In the area of the oil cooler outlet 5 there is a with this communicating oil filter inlet 10, through which the cooled crude oil enters the oil filter 8. In the housing 9 of the oil filter 8, the filter medium 17 seals off the raw from the pure oil side. After the oil has passed the filter medium 17 and left behind all the residues to be separated on it, the cleaned oil leaves the filtering device 12 through the oil filter outlet 11, which communicates with the internal combustion engine, in particular with its oil supply lines, which are not shown separately here. The coolant of the oil cooler 1, the coolant circuit Internal combustion engine is removed and is used to remove the thermal energy of the oil, enters the oil cooler inlet 6 in this, or in the oil cooler insert 3. The heat transfer takes place in countercurrent in the oil cooler or the oil cooler insert 3. After the coolant has absorbed the thermal energy of the oil, it leaves the oil cooler or its oil cooler insert 3 via the oil cooler outlet 7 and from there to the cooler of the internal combustion engine, not shown. The sealing of the short connecting piece of the oil cooler inlet or outlet 4.5 within the device for filtering 12 takes place by means of O-rings 13 which are attached on the inlet and outlet side and separate the oil side from the coolant side in the oil cooler housing 2. The connection of the oil cooler housing 2 and the housing 9 of the oil filter takes place by means of a thread, the sealing by means of an O-ring 13. The connection of the filtering device 12 to the internal combustion engine, which is not shown, takes place by means of an adapter 14, which in turn is made of screws 15 is supported. The seal between the adapter 14 and the device for filtering is carried out by means of a flat seal 16 attached between them.
Figur 1 b zeigt eine Vergrößerung des Details X aus Figur 1 a. Hierbei wird dargestellt, wie im Bereich des Ölkühlerölauslaß 5 zur sicheren Trennung des Kühlmittelbereiches vom Olkreislauf eine O-Ringdichtung 13 so auf dem kurzen Stutzen des Ölkühlereinsatzes angeordnet ist, daß die Dichtwirkung radial erfolgt.Figure 1 b shows an enlargement of the detail X from Figure 1 a. This shows how an O-ring seal 13 is arranged in the area of the oil cooler oil outlet 5 for the safe separation of the coolant area from the oil circuit so that the sealing effect is radial.
Figur 1 c zeigt ebenfalls eine Vergrößerung des Details X aus Figur 1 a. Auch hier wird dargestellt, wie im Bereich des Ölkühlerölauslaß 5 zur sicheren Trennung des Kühlmittelbereiches vom Olkreislauf O-Ringdichtungen 13 auf dem kurzen Stutzen des Ölkühlereinsatzes angeordnet sind, daß die Dichtwirkung radial erfolgt. Die Anordnung der einen oder der beiden O-Ring- Dichtungen 13 im Bereich des Ölkühlerauslaß 5 sind, obwohl nicht extra dargestellt, identisch auf den Stutzen des Olkuhleroleinlaß 4 anzuwenden. In Figur 2 a wird ein Schnitt durch einen, zwischen ein bestehendes Olfilter und eine Verbrennungskraftmaschine steckbaren Ölkühler 1 dargestellt. Der Ölkühler 1 besteht ebenfalls wie in Figur 1 a dargestellt aus einem Ölkühlergehäuse 2, in dem sich ein Ölkühlereinsatz 3 befindet. Der Ölkühlereinsatz weist einen Olkuhleroleinlaß 4 sowie einen Ölkühlerölauslaß 5 auf, über die das zu kühlende Öl Ein- bzw. Auslaß findet. Das Kühlmittel, das dem Kühlmittelkreislauf der Verbrennungskraftmaschine entnommen ist, gelangt mittels dem Ölkühlerkühlmitteleinlaß 6 in den Ölkühler, bzw. dessen Ölkühlereinsatz 3, in dem es im Gegenstrom die abzuführende Wärmeenergie des Roh-Öls im Gegenstrom aufnimmt und über den Olkuhlerkühlmittelauslaß 7 wieder in den Külkreislauf der Verbrennungskraftmaschine aus dem Ölkühlereinsatz 3 des Ölkühiersl austrägt. Das gekühlte Öl gelangt mittels Ölkühlerölauslaß 5 zum Olfiltereinlaß des nicht dargestellten, in Figur 1 a sichtbaren Olfilter, in dem es gefiltert den Weg zurück zur Verbrennungskraftmaschine, bzw. deren Schmierstellen über den Ölfilterauslaß 11 findet. Der Ölfilterauslaß 11 ist sowohl in dieser Darstellung als auch in FigurFigure 1 c also shows an enlargement of the detail X from Figure 1 a. Here too it is shown how in the area of the oil cooler oil outlet 5 for the safe separation of the coolant area from the oil circuit O-ring seals 13 are arranged on the short connecting piece of the oil cooler insert, that the sealing effect is radial. The arrangement of one or the two O-ring seals 13 in the area of the oil cooler outlet 5, although not shown separately, can be applied identically to the nozzle of the oil cooler inlet 4. FIG. 2 a shows a section through an oil cooler 1 that can be inserted between an existing oil filter and an internal combustion engine. The oil cooler 1 also consists, as shown in FIG. 1 a, of an oil cooler housing 2 in which an oil cooler insert 3 is located. The oil cooler insert has an oil cooler inlet 4 and an oil cooler oil outlet 5, via which the oil to be cooled finds inlet and outlet. The coolant, which is removed from the coolant circuit of the internal combustion engine, passes through the oil cooler coolant inlet 6 into the oil cooler or its oil cooler insert 3, in which it countercurrently absorbs the heat energy of the crude oil to be dissipated in counterflow and via the oil cooler outlet 7 back into the cooling circuit the internal combustion engine from the oil cooler insert 3 of the oil cooler. The cooled oil passes through the oil cooler oil outlet 5 to the oil filter inlet of the oil filter (not shown in FIG. 1 a), in which it is filtered and finds its way back to the internal combustion engine or its lubrication points via the oil filter outlet 11. The oil filter outlet 11 is in this illustration as well as in the figure
1 a zentral durch das Ölkühlergehäuse 2 hindurchgeführt. Die Abdichtung der kurzen Stutzen des Ölkühlerein- bzw. -auslasses 4,5 innerhalb der Vorrichtung zum Filtrieren 12 erfolgt mittels O-Ring 13, die ein- bzw. auslaßseitig angebracht sind und im Ölkühlergehäuse 2 das Öl- von der Kühlmittelseite trennen. Auch in diesem Ausführungsbeispiel sind die in den Figuren 1 b und 1 c dargestellten Dichtungs-Varianten einsetzbar.1 a centrally passed through the oil cooler housing 2. The sealing of the short connecting piece of the oil cooler inlet or outlet 4.5 within the device for filtering 12 takes place by means of O-rings 13 which are attached on the inlet and outlet sides and separate the oil side from the coolant side in the oil cooler housing 2. The sealing variants shown in FIGS. 1 b and 1 c can also be used in this exemplary embodiment.
In Figur 2 b wird eine Ansicht entlang der Linie A-A dargestellt. Zu sehen ist hier, die zentrale Durchleitung des Ölfilterauslaß 11 durch das ÖlkühlergehäuseA view along the line A-A is shown in FIG. 2b. Here you can see the central passage of the oil filter outlet 11 through the oil cooler housing
