Die Erfindung betrifft einen Kühler mit modular zusammensetzbaren Kühlerbauteilen, wie Kühlmittelrohre, zwischen den Kühlmittelrohren angeordnete Lamellen und die Kühlmittelrohre an ihren Enden miteinander verbindende Elemente.The invention relates to a cooler with modular assembled cooler components, such as coolant pipes, fins arranged between the coolant pipes and the Coolant pipes connecting at their ends Elements.

Kühler werden im allgemeinen zum Kühlen von Fluiden, z.B. Kühlwasser, Motoren- oder Getriebeölen, Luft, z.B. Ladeluft, Kältemitteln usw. und als stationäre oder mobile Einheiten verwendet. Derartige Kühler weisen in der Regel zwei einander gegenüberliegende Wasserkästen auf, in deren Rohrböden Öffnungen vorgesehen sind, in welche die Enden der Kühlmittelrohre eingeschoben sind. Zwischen den Kühlmittelrohren befinden sich die Kühllamellen, z.B. Wellrippen, über welche die Wärme an die durchtretende Luft abgegeben wird. Derartige Kühler bestehen in der Regel aus mehreren Materialien, z.B. Aluminium für die Kühlmittelrohre und die Lamellen und Kunststoff für die Wasserkästen. Unter Umständen weisen die Kühler noch Bundmetallanschlüsse oder andere Elemente auf. Auf jeden Fall besitzt ein derartiger Kühler einen vorgegebenen Aufbau, indem z.B. die Öffnungen im Rohrboden in der Regel regelmäßig und an vorgegebenen Positionen vorgesehen sind. Derartige Kühler sind für bestimmte Anwendungsfälle in ihrer Leistung optimiert bzw. auf bestimmte Einbauverhältnisse abgestimmt.Coolers are generally used to cool fluids, e.g. Cooling water, engine or gear oils, air, e.g. Charge air, Refrigerants etc. and as stationary or mobile units used. Such coolers usually have two each other opposite water boxes in their tube sheets Openings are provided in which the ends of the Coolant pipes are inserted. Between Coolant pipes are the cooling fins, e.g. Corrugated fins through which the heat to the air passing through is delivered. Such coolers usually consist of several materials, e.g. Aluminum for the coolant pipes and the fins and plastic for the water tanks. Under Under certain circumstances, the coolers still have flange metal connections or other elements. In any case has one Cooler a predetermined structure, e.g. the openings in the Pipe base usually regularly and at predetermined Positions are provided. Such coolers are for certain applications optimized in their performance or on certain installation conditions matched.

This means that the panes can be placed directly on the flat tubes be put on and no connecting means or Sealing elements between the washers and the flat tubes. A another possibility provides that the ends of the flat tubes in appropriate slots in the washers are inserted. The Flat tubes are then flowed axially.

Eine Ausführungsform sieht vor, dass die Flachrohre Turbulenzeinlagen aufweisen. Dabei sind die Flachrohre an ihrer Innen- und/oder Außenseite mit Lot platiert. Auf diese Weise können sowohl die Turbulenzeinlagen als auch die anliegenden Scheiben und Luftlamellen stoffschlüssig mit den Flachrohren verbunden werden.One embodiment provides that the flat tubes Have turbulence deposits. The flat tubes are on their inside and / or outside plated with solder. To this Both the turbulence inserts and the adjacent discs and air lamellas cohesively with the Flat tubes are connected.

Eine Weiterbildung sieht vor, dass die Flachrohre als Mehrkammerrohre oder als Sickenrohre ausgebildet sind. Auf diese Weise wird vermieden, dass sich die Flachrohre bei einem hohen Innendruck verformen.A further training provides that the flat tubes as Multi-chamber tubes or as corrugated tubes are formed. On in this way it is avoided that the flat tubes in one Deform high internal pressure.

Erfindungsgemäß entspricht die Länge der Flachrohre der Summe der Gesamtlänge zweier Scheiben und der dazwischen angeordneten Lamellen. Dabei stellen die Scheiben ein von einem Strangpressprofil abgetrenntes Teil dar. Die Herstellung eines Strangpressprofiles ist relativ einfach und preiswert. Die entsprechenden Scheiben werden von diesem Strangpressprofil in der gewünschten Dicke abgesägt, wobei die Dicke in der Regel der Höhe der Lamelle entspricht.According to the invention, the length of the flat tubes corresponds to the sum the total length of two discs and the one in between arranged slats. The discs adjust from an extruded part. The manufacture an extruded profile is relatively simple and inexpensive. The corresponding discs are from this Sawed extruded profile in the desired thickness, the Thickness usually corresponds to the height of the slat.

Eine spezielle Ausführungsform sieht vor, dass die Scheibe als Anschlussstück ausgebildet ist und einen zum Durchbruch orthogonalen Anschlusskanal aufweist. Über den Durchbruch werden die einzelnen Flachrohre mit dem zu kühlenden Medium versorgt, wobei das Medium über den Anschlusskanal in das Anschlussstück eingeleitet bzw. aus diesem ausgeleitet wird. Eine einfache Version sieht dagegen vor, dass die Einleitung bzw. Ausleitung des zu kühlenden Mediums direkt über den Durchbruch erfolgt. Der Kühler ist also auch hinsichtlich seiner Anschlüsse extrem variabel und kann seitlich und von oben bzw. unten angeströmt werden.A special embodiment provides that the disc as Connection piece is formed and a breakthrough has orthogonal connection channel. About the breakthrough the individual flat tubes with the medium to be cooled supplied, the medium via the connection channel in the Connection piece initiated or is derived from this. A simple version, however, provides that the introduction or discharge of the medium to be cooled directly via the Breakthrough. The cooler is also regarding Its connections are extremely variable and can be adjusted from the side and from flow to the top or bottom.

In bevorzugter Weise besitzt die Scheibe wenigstens die Höhe, die der Gesamthöhe zweier Lamellen mit einem dazwischen angeordneten Flachrohr oder Flachmaterial entspricht. Derartige Scheiben sind z.B. auch dann erforderlich, wenn der Anschlusskanal einen relativ großen Durchmesser aufweist und daher nicht in einer normalen Scheibe unterzubringen ist. Bei Scheiben mit größerer Höhe werden in der Regel zwei scheiben zusammengefasst, wobei das Flachrohr nicht an der Flachseite der Scheibe anliegt sondern in einen zum Durchbruch orthogonalen Schlitz eingeschoben ist. Das Flachrohr ist stirnseitig offen und der Schlitz ist mit dem Durchbruch verbunden. Das Flachrohr wird in diesem Schlitz fluiddicht eingelötet und dadurch an den Versorgungskanal angeschlossen.The disk preferably has at least the height, the total height of two slats with one in between arranged flat tube or flat material corresponds. Such discs are e.g. also required if the Connection channel has a relatively large diameter and therefore cannot be accommodated in a normal disc. At Disks with a greater height will usually have two disks summarized, the flat tube not on the flat side the disc rests but in a breakthrough orthogonal slot is inserted. The flat tube is open on the face and the slot is with the opening connected. The flat tube becomes fluid-tight in this slot soldered in and thus connected to the supply channel.

Bei einer anderen Variante ist vorgesehen, dass die Scheibe zwei oder mehrere, nebeneinander liegende Durchbrüche aufweist und zwei oder mehrere Flachrohre nebeneinander auf dieser Scheibe angeordnet sind. Hierdurch wird die Möglichkeit geschaffen, dass in einem einzigen Kühler mehrere Medien gleichzeitig gekühlt werden, wobei die Flachrohre lediglich über die Scheiben miteinander verbunden sind. Dadurch besteht die Möglichkeit, dass jedes Flachrohr eigene Lamellen aufweist oder dass die Flachrohre über eine gemeinsame Lamelle zusätzlich miteinander verbunden sind.Another variant provides that the disc has two or more breakthroughs lying side by side and two or more flat tubes next to each other on this Disc are arranged. This will give you the opportunity created that multiple media in a single cooler be cooled at the same time, the flat tubes only are connected to each other via the disks. As a result the possibility that each flat tube has its own fins or that the flat tubes have a common fin are also connected to each other.

Wie bereits erwähnt, können übereinander liegende Flachrohre mit unterschiedlich hohen Lamellen bzw. mit unterschiedlich dichten Lamellenpackungen miteinander verbunden sein. Auf diese Weise wird die Leistung des Kühlers an die Anforderungen angepasst. Außerdem kann der Kühler ein partiell sich änderndes Leistungsprofil aufweisen. Dabei sind den unterschiedlich hohen Lamellen unterschiedlich hohe Scheiben zugeordnet.As already mentioned, flat tubes lying one above the other can with different height slats or with different dense lamellar packs are connected. On this way the performance of the cooler will meet the requirements customized. In addition, the cooler can be a partial himself have a changing performance profile. Here are the slats of different heights slices of different heights assigned.

Kühler für zwei oder mehrere zu kühlende Medien können so ausgestaltet sein, dass Flüssigkeiten und/oder Gase gleichzeitig kühlbar sind.This allows coolers for two or more media to be cooled be designed that liquids and / or gases are coolable at the same time.

Ferner kann bei einem Ausführungsbeispiel vorgesehen sein, dass die Breite und/oder die Tiefe des Kühlers über dessen Höhe variieren. Die Form des Kühlers kann auf diese Weise optimal an die örtlichen Gegebenheiten angepasst werden.Furthermore, in one embodiment, that the width and / or depth of the cooler is above it Vary in height. The shape of the cooler can be done this way can be optimally adapted to the local conditions.

Die Erfindung betrifft auch ein Verfahren zur Herstellung eines Kühlers, wobei die Flachrohre, Scheiben, Lamellen und ggf. Anschlussstücke zuerst in einer Kassette kassettiert werden und anschließend in einem Lötofen die Bauteile miteinander zum fertigen Kühler miteinander verlötet werden. Nach dem Lötvorgang bedarf es keinerlei Nacharbeit am Kühler was zum einen den Vorteil hat, dass der Fertigungsaufwand auf ein Minimum reduziert ist, und dass eventuelle, bei einer Nacharbeit anfallende Verschmutzungen vermieden werden.The invention also relates to a method of manufacture a cooler, the flat tubes, discs, fins and If necessary, the connection pieces are first cased in a cassette and then the components in a soldering furnace are soldered together to form the finished cooler. After the soldering process, no rework on the cooler is required which on the one hand has the advantage that the manufacturing effort a minimum is reduced, and that eventual, at a Rework soiling can be avoided.

Die Figur 1 zeigt ein erstes Ausführungsbeispiel eines insgesamt mit 1 bezeichneten Kühlers für stationäre und mobile Anlagen. Dieser Kühler 1 wird in Richtung der Pfeile 2 von Luft durchströmt. Der Einfachheit halber sind lediglich im unteren und im oberen Bereich die Bauelemente des Kühlers 1 dargestellt, die sich jedoch über die gesamte Höhe des Kühlers 1 erstrecken. Den unteren und oberen Abschluss bilden ein Flachmaterial 3, an dem eine Lamelle 4, bzw. eine Wellrippe 5 sowie an den seitlichen Enden eine Scheibe 6 sowie ein Anschlussstück 7 anliegen. Es folgen ein Flachrohr 8 sowie eine weitere Wellrippe 5 mit Scheibe 6. Dieser Aufbau setzt sich nun fort bis zum anderen Flachmaterial 3. Am unteren Ende befindet sich ein weiteres Anschlussstück 9, bei dem ein Anschlusskanal 10' sichtbar ist. Figure 1 shows a first embodiment of a total designated 1 cooler for stationary and mobile Investments. This cooler 1 is in the direction of arrows 2 from Air flows through. For the sake of simplicity are only in the components of the cooler 1 shown, however, over the entire height of the cooler 1 extend. The bottom and top finishes form a Flat material 3 on which a lamella 4 or a corrugated fin 5 and at the lateral ends a disc 6 and a Fit connector 7. There follows a flat tube 8 as well another corrugated fin 5 with washer 6. This structure sets now continue to the other flat material 3. At the lower end there is another connector 9, in which a Connection channel 10 'is visible.

Die Figur 2 zeigt eine Scheibe 6, die ein Teil eines Strangpressprofils ist. Die Scheibe 6 wird in der gewünschten Dicke vom Strangpressprofil abgesägt. Zur Führung des zu kühlenden Mediums weist die Scheibe 6 einen zentralen Durchbruch 11 auf, der beim dargestellten Ausführungsbeispiel eine längliche Form besitzt. Es ist jedoch auch denkbar, dass anstelle eines einzigen Durchbruchs 11 die Scheibe 6 mit mehreren Durchbrüchen, die nebeneinander liegen, versehen ist.Figure 2 shows a disc 6, which is part of a Extruded profile is. The disc 6 is in the desired Sawed off the thickness of the extruded profile. To guide the cooling medium, the disc 6 has a central Breakthrough 11 on that in the illustrated embodiment has an elongated shape. However, it is also conceivable that instead of a single opening 11, the disc 6 with several breakthroughs that are next to each other is provided.

Die Figur 3 zeigt das Ende des Flachrohres 8, welches ebenfalls mit einem Durchbruch 12 versehen ist, der die Form des Durchbruchs 11 aufweist. In das Flachrohr 8 ist eine Turbulenzeinlage 13 eingeschoben, die teilweise sichtbar ist. Stirnseitig ist das Flachrohr 8 über einen Einsatz 14, der stirnseitig eingeschoben ist, verschlossen.Figure 3 shows the end of the flat tube 8, which is also provided with an opening 12, the shape of the breakthrough 11. In the flat tube 8 is one Turbulence insert 13 inserted, which is partially visible. The end face of the flat tube 8 is via an insert 14 which is inserted at the front, closed.

Die Figur 4 zeigt das Anschlussstück 7 bzw. 9, welches im Querschnitt der Scheibe 6 entspricht. Das Anschlussstück 7 bzw. 9 weist ebenfalls den Durchbruch 11 auf, besitzt jedoch eine größere Höhe. Die Höhe entspricht der Summe der Höhe zweier Wellrippen 5 und der Höhe eines Flachrohres 8, wie sich deutlich aus Figur 1 ergibt. Orthogonal zum Durchbruch 11 erstreckt sich der Anschlusskanal 10, der mit dem Durchbruch 11 fluidverbunden ist. Außerdem weist das Anschlussstück 7 bzw. 9 einen seitlichen Schlitz 15 auf, was in Figur 5 erkennbar ist. In diesen seitlichen Schlitz 15 ist ein Ende eines Flachrohres 8' eingeschoben. Dieses Ende des Flachrohres 8' besitzt eine zum Ausführungsbeispiel des Flachrohres 8 der Figur 3 alternative Ausbildung und ist stirnseitig offen. Dieses Flachrohr 8' wird also direkt stirnseitig angeströmt.Figure 4 shows the connector 7 or 9, which in Cross section of the disc 6 corresponds. The connector 7 or 9 also has the opening 11, but has a greater height. The height corresponds to the sum of the height two corrugated fins 5 and the height of a flat tube 8, as is clearly shown in Figure 1. Orthogonal to breakthrough 11 extends the connection channel 10, which with the breakthrough 11 is fluid-connected. In addition, the connector 7 or 9 a lateral slot 15, which in Figure 5 is recognizable. In this side slot 15 is one end a flat tube 8 'inserted. This end of the flat tube 8 'has an embodiment of the flat tube 8 of the Figure 3 alternative training and is open on the front. This flat tube 8 'is thus flowed directly to the front.

Die Figur 6 zeigt einen Querschnitt VI-VI durch das Flachrohr 8 in der Figur 3, wobei deutlich der Durchbruch 12, die Turbulenzeinlage 13 sowie der Einsatz 14 erkennbar sind. Sowohl der Einsatz 14 als auch die Turbulenzeinlage 13 werden durch eine Verlötung im Flachrohr 8 bzw. die Turbulenzeinlage 13 im Flachrohr 8' befestigt. Hierfür ist die Innenseite des Flachrohres 8 bzw. 8' mit Lot plattiert. Die Befestigung des Flachrohres 8' im Anschlussstück 7 bzw. 9 erfolgt ebenfalls durch eine Verlötung, wofür das Flachrohr 8' an seiner Außenseite mit Lot plattiert ist.Figure 6 shows a cross section VI-VI through the flat tube 8 in Figure 3, clearly showing the breakthrough 12, the Turbulence insert 13 and the insert 14 are recognizable. Both the insert 14 and the turbulence insert 13 are by soldering in the flat tube 8 or the turbulence insert 13 attached in the flat tube 8 '. For this, the inside of the Flat tube 8 or 8 'plated with solder. The attachment of the Flat tube 8 'in the connector 7 or 9 also takes place by soldering, for which the flat tube 8 'on his The outside is plated with solder.

Die Figur 7 zeigt den Schnitt VII-VII durch das Flachrohr 8 gemäß Figur 3 und es sind ebenfalls deutlich der Einsatz 14 und die Turbulenzeinlage 13 erkennbar. Über den Einsatz 14 wird die Turbulenzeinlage 13 im Flachrohr 8 zentriert und bis zur Verlötung festgehalten.FIG. 7 shows the section VII-VII through the flat tube 8 3 and the insert 14 is also clearly shown and the turbulence insert 13 can be seen. About the mission 14 the turbulence insert 13 is centered in the flat tube 8 and up held for soldering.

Die Figur 8 zeigt ein Ausführungsbeispiel einer Wellrippe 5, die eine trapezförmige Welle besitzt. Es ist jedoch auch denkbar, dass die Welle mit gerundeten Enden hergestellt wird. Die Höhe der Wellrippe 5 entspricht der Höhe der Scheibe 6. Die Befestigung der Wellrippe 5 und der Scheiben 6 bzw. Anschlussstücke 7 und 9 an den Flachrohren 8 erfolgt ebenfalls über eine Verlötung, wofür das Flachrohr 8 außenseitig mit Lot plattiert ist.FIG. 8 shows an embodiment of a corrugated fin 5, which has a trapezoidal wave. However, it is also conceivable that the shaft is made with rounded ends. The height of the corrugated fin 5 corresponds to the height of the disk 6. The fastening of the corrugated fin 5 and the washers 6 or Connections 7 and 9 on the flat tubes 8 also take place via soldering, for which purpose the flat tube 8 is soldered on the outside is plated.

Die Figur 9 zeigt ein zweites Ausführungsbeispiel des erfindungsgemäßen Kühlers 1, mit dem z.B. Kühlwasser und Getriebeöl gekühlt werden können. Zur Kühlung des Kühlwassers weist der Kühler 1 einen ersten Bereich 16 und zur Kühlung des Getriebeöls einen zweiten Bereich 17 auf. Das Kühlwasser tritt z.B. über einen Anschlussstutzen 18 in das Anschlussstück 7 und somit in den Kühler 1 ein. Dort wird das Kühlwasser über die Durchbrüche 11 in die einzelnen Flachrohre 8 verteilt. Das Kühlwasser durchströmt die Flachrohre und wird am anderen Ende über die einzelnen Scheiben 6 gesammelt und tritt am Anschlussstück 9, bzw. über einen weiteren Anschlussstutzen 19 wieder aus. Es sei noch angemerkt, dass zwischen den beiden Anschlussstücken 7 und 9 eine Wellrippe 5 angeordnet ist, die die Höhe der Anschlussstücke 7 und 9 aufweist. Es befindet sich also kein Flachrohr 8' zwischen diesen beiden Anschlussstücken 7 und 9.FIG. 9 shows a second embodiment of the cooler 1 according to the invention, with which e.g. Cooling water and Gear oil can be cooled. For cooling the cooling water the cooler 1 has a first region 16 and for cooling the Gear oil a second area 17. The cooling water occurs e.g. via a connecting piece 18 into the connector 7 and thus in the cooler 1. There the cooling water is over the openings 11 distributed in the individual flat tubes 8. The Cooling water flows through the flat tubes and is at the other end collected over the individual disks 6 and occurs on Connection piece 9, or via a further connection piece 19 out again. It should be noted that between the two Connections 7 and 9 a corrugated fin 5 is arranged, the has the height of the connectors 7 and 9. It is So there is no flat tube 8 'between these two Connectors 7 and 9.

Das zu kühlende Öl tritt über den Anschlusskanal 10 in das Anschlussstück 7 des zweiten Bereichs 17 ein und wird, wie das zu kühlende Wasser, über die Durchbrüche 11 in die einzelnen Flachrohre 8 des zweiten Bereichs 17 verteilt. Nach dem Durchströmen der Flachrohre 8 wird das gekühlte Öl gesammelt und tritt am Anschlusskanal 10 des Anschlussstücks 9 wieder aus. The oil to be cooled enters through the connection channel 10 Connector 7 of the second area 17 and is like that water to be cooled, through the openings 11 in the individual Flat tubes 8 of the second area 17 distributed. After this The cooled oil flows through the flat tubes 8 and occurs at the connection channel 10 of the connector 9 again out.

Es wird darauf hingewiesen, dass die Flachrohre 8 des zweiten Bereichs 17 mit Wellrippen 5' versehen sind, die sich nicht nur über die Flachrohre 8 des zweiten Bereichs sondern auch über die Flachrohre 8 des ersten Bereichs erstrecken und somit die nebeneinander liegenden Flachrohre 8 der beiden Bereiche 16 und 17 miteinander verbinden. Dies trifft auch für die Scheiben 6' zu. Diese Scheiben 6' sind mit jeweils zwei Durchbrüchen 11 versehen, wobei ein Durchbruch für die Flachrohre 8 des ersten Bereichs 16 und ein Durchbruch für die Flachrohre 8 des zweiten Bereichs 17 bestimmt sind.It should be noted that the flat tubes 8 of the second Area 17 are provided with corrugated ribs 5 ', which are not only over the flat tubes 8 of the second area but also Extend over the flat tubes 8 of the first area and thus the adjacent flat tubes 8 of the two areas Connect 16 and 17 together. This also applies to them Discs 6 'too. These discs 6 'are two each Breakthroughs 11 provided, a breakthrough for the Flat tubes 8 of the first area 16 and a breakthrough for the Flat tubes 8 of the second region 17 are determined.

Es sei noch angemerkt, dass es nicht unbedingt erforderlich ist, dass die Wellrippen 5' sich über die Flachrohre 8 beider Bereiche 16 und 17 erstrecken. Es können auch Wellrippen verwendet werden, die sich lediglich über die zugeordneten Flachrohre 8 erstrecken.It should be noted that it is not absolutely necessary is that the corrugated fins 5 'over the flat tubes 8 of both Areas 16 and 17 extend. Corrugated fins can also be used are used, which are only about the assigned Extend flat tubes 8.

Der obere und untere Abschluss des Kühlers 1 erfolgt über Flachmaterial 3, wobei das untere Flachmaterial 3 die Tiefe des gesamten Kühlers 1 besitzt.The upper and lower end of the cooler 1 takes place via Flat material 3, the lower flat material 3 the depth of the entire cooler 1.

Die Figur 10 zeigt ein weiteres Ausführungsbeispiel des erfindungsgemäßen Kühlers 1, bei dem ein erster, oberer Bereich 20 und ein zweiter, unterer Bereich 21 vorgesehen sind. Der erste, obere Bereich 20 dient zur Kühlung von Wasser und besitzt eine größere Breite als der untere, zweite Bereich 21. Die Versorgung des oberen Bereichs 20 erfolgt über ein Anschlussstück 7, welches zwei Anschlusskanäle 10 und 10' aufweist. Mit dem Anschlusskanal 10 sind die Durchbrüche 11 der Scheiben 6 des ersten Bereichs 20 verbunden, über welche das Wasser in die Flachrohre 8 verteilt wird. Das gekühlte Wasser wird dem Anschlussstück 9, insbesondere dessen Anschlusskanal 10 entnommen.FIG. 10 shows a further embodiment of the Radiator 1 according to the invention, in which a first, upper Area 20 and a second, lower area 21 are provided are. The first, upper area 20 serves to cool water and has a larger width than the lower, second area 21. The supply of the upper area 20 takes place via a Connector 7, which has two connecting channels 10 and 10 ' having. The openings 11 are provided with the connection channel 10 connected to the disks 6 of the first region 20, via which the water is distributed into the flat tubes 8. The chilled Water is the connector 9, especially its Connection channel 10 removed.

Das zu kühlende Öl tritt über den Anschlusskanal 10' in das Anschlussstück 7 ein. Orthogonal zum Anschlusskanal 10' weist das Anschlussstück 7 einen Durchbruch auf, der mit den Durchbrüchen der Scheiben 6 des zweiten Bereichs 21 fluchtet. Auf diese Weise wird das zu kühlende Öl in die Flachrohre 8 des zweiten Bereichs 21 verteilt. Das gekühlte Öl wird über den Anschlusskanal 10' dem Anschlussstück 9 wieder entnommen.The oil to be cooled enters through the connection channel 10 ' Connector 7 a. Points orthogonal to the connection channel 10 ' the connector 7 a breakthrough with the Breakthroughs of the panes 6 of the second region 21 are aligned. In this way, the oil to be cooled is fed into the flat tubes 8 of the second area 21 distributed. The chilled oil is over the connection channel 10 'removed from the connector 9 again.

Aus den Figuren 9 und 10 ist deutlich erkennbar, dass die Form des Kühlers 1 problemlos an vorgegebene Einbaumaße angepasst werden kann, indem längere oder kürzere Flachrohre 8 und Wellrippen 5 und evtl. modifizierte Anschlussstücke 7 verwendet werden.It can be clearly seen from FIGS. 9 and 10 that the shape of the cooler 1 easily adapted to the specified installation dimensions can be made by using longer or shorter flat tubes 8 and Corrugated fins 5 and possibly modified connecting pieces 7 be used.

Es sei noch darauf hingewiesen, dass anstelle des in der Figur 10 dargestellten Anschlussstücks 7 bzw. 9, welches mit zwei Anschlusskanälen 10 bzw. 10' und zwei Durchbrüchen 11 versehen ist, auch zwei herkömmliche Anschlussstücke 7 bzw. 9, die nebeneinander gesetzt werden, verwendet werden können. It should also be noted that instead of that in the figure 10 shown connector 7 and 9, which with two Connection channels 10 and 10 'and two openings 11 are provided is, also two conventional connectors 7 and 9, respectively placed side by side, can be used.

Die Figur 11 zeigt ein weiteres Ausführungsbeispiel des erfindungsgemäßen Kühlers, mit dem drei Medien, nämlich Wasser, Luft und Öl gekühlt werden können. Der Eintritt des Wassers erfolgt über einen Durchbruch 22 im oberen Flachmaterial 3, wobei dieser Durchbruch 22 mit dem Durchbruch 11 der darunterliegenden Scheiben 6 fluchtet. Auf diese Weise werden die im Bereich 23 sich befindenden Flachrohre 8 mit dem zu kühlenden Wasser versorgt. Die Entnahme des gekühlten Wassers erfolgt über einen Durchbruch 24, der ebenfalls im Flachmaterial 3 vorgesehen ist.FIG. 11 shows a further embodiment of the cooler according to the invention, with the three media, namely Water, air and oil can be cooled. The entry of the Water takes place through an opening 22 in the upper Flat material 3, this opening 22 with the opening 11 of the underlying discs 6 are aligned. In this way are located in the area 23 flat tubes 8 with the water to be cooled. The removal of the chilled Water takes place via an opening 24, which is also in the Flat material 3 is provided.

Das zweite Medium, nämlich Luft, tritt am Anschlusskanal 10 des Anschlussstücks 7 ein. Der Austritt der gekühlten Luft erfolgt über den Anschlusskanal 10' am Anschlussstück 9. Zwischen dem Anschlussstück 7 und dem Anschlussstück 9 befindet sich ein Trennelement, so dass die zu kühlende Luft nicht direkt über die einzelnen Durchbrüche 11 und 12 vom Anschlussstück 7 in das Anschlussstück 9 überströmen kann, sondern die jeweiligen Flachrohre 8 durchströmen muss. Dieses Trennelement kann in Form einer Scheibe 6', die im Bereich 25 keinen Durchbruch aufweist, oder in Form eines Flachmaterials, welches den Durchbruch einer Scheibe 6 verschließt, verwirklicht sein.The second medium, namely air, occurs at the connection duct 10 of the connector 7 a. The outlet of the cooled air takes place via the connection channel 10 'on the connector 9. Between the connector 7 and the connector 9 there is a separating element so that the air to be cooled not directly on the individual breakthroughs 11 and 12 from Can flow over connector 7 into connector 9, but must flow through the respective flat tubes 8. This The separating element can be in the form of a disk 6 'which is in the region 25 has no breakthrough, or in the form of a flat material, which closes the opening of a pane 6, be realized.

Das dritte Medium, wie z.B. zu kühlendes Öl, tritt über einen Anschlusskanal 10 in das Anschlussstück 7 im Bereich 26 ein und verlässt diesen Bereich 26 über den Anschlusskanal 10' des Anschlussstücks 9. Zwischen den beiden Anschlussstücken 7 und 9 befindet sich ein Flachmaterial.The third medium, e.g. Oil to be cooled passes over one Connection channel 10 in the connector 7 in the area 26 and leaves this area 26 via the connection channel 10 'of the Connector 9. Between the two connectors 7 and 9 is a flat material.

Die Figur 12 zeigt ein weiteres Ausführungsbeispiel des Kühlers 1 in Seitenansicht, wobei deutlich Befestigungsbohrungen 28 erkennbar sind, die in einigen Scheiben 6 vorgesehen sind.

Direkt unterhalb des Anschlussstücks 7 befindet sich eine Scheibe 6', welche keinen Durchbruch aufweist. Eine derartige Scheibe 6' befindet sich auch unterhalb des Anschlussstücks 9 und auf gleicher Ebene auf der gegenüberliegenden Seite des Kühlers 1. Auf diese Weise wird der Kühler 1 in einen oberen Bereich zur Kühlung von Wasser und in einen unteren Bereich zur Kühlung von Getriebeöl unterteilt. Das heiße Getriebeöl strömt über den Anschlusskanal 10 in das Anschlussstück 7 ein und über den Anschlusskanal 10' aus dem Anschlussstück 9 aus. Eine Trennung erfolgt hier ebenfalls über eine Scheibe 6' ohne Durchbruch.FIG. 12 shows a further embodiment of the Radiator 1 in side view, clearly Mounting holes 28 can be seen in some Disks 6 are provided.
