Die Erfindung betrifft einen Wärmetauscher mit zwischen Verteilern in Abständen zur Aufnahme von Blechrippen angeordneten Wärmetauscherrohren, deren Enden rechteckförmig, in Verteilerlängsrich tung erweitert ausgebildet und Seite an Seite in einem Schlitz der Verteiler eingesetzt sind. Ein Wärmetauscher dieser Gattung ist durch die schweizerische Patentschrift 351 622 bekannt.The invention relates to a heat exchanger with between distributors at intervals for receiving Sheet metal ribs arranged heat exchanger tubes, the ends of which are rectangular, in the longitudinal direction of the distributor device expanded and are used side by side in a slot in the manifold. A heat exchanger this genus is known from Swiss patent 351 622.

Bei dem bekannten Wärmetauscher bestehen die Verteiler aus rechteckigen Rahmen mit einem U-Profil, in die von der einen Seite her die erweitert ausgebildeten rechteckigen Enden der Wärmetauscherrohre eingesetzt sind, während der Rand der Haube zwischen die beiden Schenkel des U-Profils des Rahmens gelötet ist. Die Haube und der Rahmen müssen jeweils für eine bestimmte Länge des Wärmetauschers eigens paßgerecht hergestellt werden. Dadurch ist sowohl die Herstellung des Verteilers als auch der Zusammenbau mit den Wärmetauscherrohren verteuertIn the known heat exchanger, the distributors consist of rectangular frames with a U-profile, into the expanded rectangular ends of the heat exchanger tubes from one side are inserted, while the edge of the hood is soldered between the two legs of the U-profile of the frame is. The hood and the frame must each be specially designed for a specific length of the heat exchanger be manufactured to fit. This is both the manufacture of the manifold and the assembly made more expensive with the heat exchanger tubes

Ferner ist aus der deutschen Patentschrift 615 357 ein Kühler für Turbogeneratoren bekannt, bei dem die Kühlrohre in beidseitig angeordnete Rechtkantrohre eingewalzt sind. Bei der vorliegenden Erfindung wird jedoch das kostspielige Einwalzen der Rohre nicht in Betracht gezogen. Gleiches gilt auch für einen aus dem deutschen Gebrauchsmuster 1 684 436 bekannten Wärmetauscher, bei dem zwecks leichterer Montage und größerer Wechselbeanspruchbarkeit die Rohrenden in konische Kragen der Rohrböden gesteckt und angeschweißt sind, wobei die Kragen von der Verteilerkammer her gesehen nach innen umge bördelt sind. Bei der Erfindung soll jedoch die Vielzahl der Öffnungen zum Einsetzen der Wärme tauscherrohre vermieden werden.Furthermore, from German Patent 615 357 a cooler for turbo generators is known in which the cooling tubes are rolled into rectangular tubes arranged on both sides. In the present invention however, the costly rolling in of the tubes is not taken into account. The same also applies to a heat exchanger known from the German utility model 1 684 436, in which for the purpose of lighter For assembly and greater alternating load capacity, the pipe ends are inserted into the conical collars of the pipe sheets and are welded on, the collars being turned inwards when viewed from the distribution chamber are beaded. In the invention, however, the plurality of openings is intended for the application of heat exchanger tubes are avoided.

Die der Erfindung zugrunde liegende Aufgabe besteht deshalb darin, ausgehend von dem eingangs ge nannten Wärmetauscher die Verteiler so auszubilden, daß sowohl die Herstellungsweise der Verteiler selbst, als auch der Einbau der Rohre in der richtigen un verrückbaren Lage in die Verteiler erleichtert wird. Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Verteiler als annähernd rechteckförmiges stranggepreßtes Schlitzrohr ausgebildet sind und der Schlitz von den nach innen umgebogenen Längslappen einer Schlitzrohrseite gebildet ist.The object underlying the invention is therefore based on the ge initially called heat exchangers to design the distributors in such a way that both the manufacturing method of the distributors themselves, as well as the installation of the pipes in the correct immovable position in the manifold is made easier. According to the invention, this object is achieved in that the distributors are approximately rectangular extruded slotted tube are formed and the Slot is formed by the inwardly bent longitudinal tabs of a slotted tube side.

Der Vorteil liegt dabei darin, daß das den Verteiler bildende Schlitzrohr in einem einzigen Arbeitsgang als endloses Rohr gepreßt werden kann. Von diesem Schlitzrohr werden die benötigten Längen abgeschnit ten, worauf die Wärmetauscherrohre eingesetzt und verschweißt und alsdann die Endstücke auf die noch offenen Stirnseiten der Schlitzrohre aufgesetzt wer-Wärmetauscher mit Rohren, die in einen Schlitz der zugehörigen Verteiler eingesetzt sindThe advantage here is that the slotted tube forming the distributor can be done in a single operation can be pressed as an endless tube. The required lengths are cut from this slotted tube ten, whereupon the heat exchanger tubes are inserted and welded and then the end pieces on the still Open end faces of the slotted tubes were put on who-heat exchangers with tubes, which in a slot the associated distributors are used

den. Die nach innen umgebogenen Längslappen ermöglichen ein einfaches Einstecken der Wärmetauscherrohre sowie deren richtige Lage. Ferner wird durch das Schlitzrohr die Gefahr von Undichtheiten beträchtlich verringert.the. The inwardly bent longitudinal tabs allow the heat exchanger tubes to be easily inserted as well as their correct position. Furthermore, the slotted tube increases the risk of leaks considerably reduced.

In vorteilhafter Ausgestaltung der Erfindung sind an der den Schlitz aufweisenden Seite des Rohres nach außen vorstehende Sperrleisten zur Abweisung des Luftstroms von den nicht mit Blechrippen versehenen Lücken zwischen den Rohrenden angeformt. In an advantageous embodiment of the invention, on the side of the tube having the slot Outwardly protruding blocking strips to reject the air flow from the gaps between the pipe ends that are not provided with sheet metal ribs.

Diese Maßnahme trägt zu einem besseren Wärmetausch bei. This measure contributes to a better heat exchange.

Soll einer der Verteiler zusätzlich als Ölkühler ausgebildet werden, so weist nach einer weiteren Aus gestaltung wenigstens ein Verteiler einstückig eine innere Querwand zur Abteilung und Einlaß- und Auslaßstutzen in jeder der Abteilungen auf. Auch hierfür ist die Herstellungsweise einfach. Schließlich kann in vorteilhafter Weise wenigstens eine Seite der Querwand mit mehreren Rippen versehen sein, die einstückig mit dieser Querwand geformt sind.Should one of the distributors also be designed as an oil cooler be, so has according to a further embodiment at least one distributor in one piece inner bulkhead to the compartment and inlet and outlet ports in each of the compartments. Even the manufacturing method for this is simple. Finally, at least one side of the Transverse wall can be provided with a plurality of ribs which are molded in one piece with this transverse wall.

Der in F i g. 1 dargestellte Wärmetauscher besteht aus zwei in Längsrichtung parallel angeordneten Ver teilern 10, 11 und mehreren auf Abstand gehaltenen Rohren 12, die sich zwischen den Verteilern 10, 11 erstrecken. Zur Verbesserung des Wärmetauschers sind mehrere Blechrippen 13 in den Zwischenräumen zwischen den Rohren 12 vorgesehen.The in F i g. 1 shown heat exchanger consists of two parallel arranged in the longitudinal direction Ver dividers 10, 11 and a plurality of spaced apart pipes 12 extending between the manifolds 10, 11 extend. To improve the heat exchanger, several sheet metal ribs 13 are in the spaces provided between the tubes 12.

Die im Strangpreßverfahren hergestellten Verteiler 10 und 11 sind vorzugsweise aus Aluminium gefertigt. Die Verteiler sind als annähernd rechteckförmige Schlitzrohre ausgebildet. Der obere Verteiler 10 in Fig. 1 besteht aus einer oberen Wand 14, Seitenwänden 15 und 16 und einer unteren Wand 17. An der oberen Wand 14 ist ein durchgehender Flansch 18 angeformt, von dem jedoch ein Teil entfernt ist (wie aus Fig. 1 ersichtlich) und der Öffnungen 19 zur Befestigung des Wärmetauschers aufweist. Die untere Wand 17 des Verteilers 10 hat zwei sich nach unten erstreckende Sperrleisten20, 21 (s. Fig. 2). zwischen denen die Blechrippen zu liegen kommen und welche verhindern, daß der Luftstrom zwischen den nicht mit Blechrippen 13 versehenen Enden der Rohre hindurchgeleitet wird. Somit gelangt der Luftstrom zwecks Verbesserung des Wärmetausches in durch den mit Blechrippen versehenen Bereich der Rohre. Die untere Wand 17 hat zwei auf Abstand gehaltene, sich nach oben erstreckende Längslappen 17 a und 17 b, welche einen in Längsrichtung verlaufenden Schlitz 22 zur Aufnahme der Enden der Rohre 12 bilden. Eine Öffnung 23 in der oberen Wand 14 dient als Kühlmittelzufuhr; fernerhin sind dort ein Überlaufstutzen 24 und eine Öffnung 25 für einen Kühlmittel-Einlaßrohrstutzen 26 vorgesehen, Schließlich sind noch zwei Endstücke bildende Kappen 27, 28 an den Enden des Verteilers 10 angeschweißt oder anderweitig befestigt.The manifolds 10 and 11 produced by extrusion are preferably made of aluminum. The distributors are designed as approximately rectangular slotted tubes. The upper distributor 10 in FIG. 1 consists of an upper wall 14, side walls 15 and 16 and a lower wall 17. A continuous flange 18 is formed on the upper wall 14, but a part of which is removed (as in FIG. 1 can be seen) and has openings 19 for fastening the heat exchanger. The lower wall 17 of the manifold 10 has two downwardly extending locking strips 20, 21 (see Fig. 2). between which the sheet metal fins come to lie and which prevent the air flow from being passed between the ends of the tubes which are not provided with sheet metal fins 13. Thus, in order to improve the heat exchange, the air flow passes through the area of the tubes provided with sheet metal fins. The lower wall 17 has two upwardly extending longitudinal tabs 17 a and 17 b which are kept at a distance and which form a slot 22 running in the longitudinal direction for receiving the ends of the tubes 12. An opening 23 in the upper wall 14 serves as a coolant supply; Furthermore, an overflow connection 24 and an opening 25 for a coolant inlet pipe connection 26 are provided there. Finally, two end pieces forming caps 27, 28 are welded or otherwise fastened to the ends of the distributor 10.

Der untere Verteiler 11 weist im wesentlichen die gleiche Ausbildung wie der Verteiler 10 auf. Wie aus F i g. 3 ersichtlich, hat der Verteiler 11 eine untere Wand 30, Seitenwände 31 und 32 sowie eine obere Wand 33. An der unteren Wand 30 befindet sich ein vorstehender Flansch 34, von welchem, wie bei dem Flansch 18 des Verteilers 10, ein Teil entfernt ist und der Öffnungen 35 zum Befestigen aufweist. An der oberen Wand 33 befinden sich fernerhin zwei aufwärts gerichtete Sperrleisten 36, 37, zwischen denen die Blechrippen zu liegen kommen. Die obere Wand 33 hat ebenfalls zwei, sich nach unten erstreckende Längslappen 33 α und 33 b, die einen in der Längsrichtung verlaufenden Schlitz 38 für die Aufnahme des unteren Endes der Rohre 12 bilden. In der unteren Wand 30 des Verteilers 11 befinden sich öffnungen 40 für die Stutzen 42 und 43 eines Ölkühlers 44. Eine Öffnung 45 ist in der Wand 32 für die Aufnahme eines Kühlmittelauslaßstutzens 46 vorgesehen. Außerdem weist die Wand 32 einen Gewindestutzen 47 und ein Absperrorgan 48 auf. Zwei Kappen 50, 51 sind an die Enden des Verteilers 11 angeschweißt odei anderweitig befestigt.The lower distributor 11 has essentially the same design as the distributor 10. As shown in FIG. 3, the manifold 11 has a bottom wall 30, side walls 31 and 32 and an upper wall 33. On the bottom wall 30 there is a protruding flange 34 from which, as with the flange 18 of the manifold 10, a portion is removed and which has openings 35 for fastening. On the upper wall 33 there are also two upwardly directed locking strips 36, 37, between which the sheet metal ribs come to lie. The upper wall 33 also has two downwardly extending longitudinal tabs 33 a and 33 b, which form a slot 38 running in the longitudinal direction for receiving the lower end of the tubes 12. In the lower wall 30 of the distributor 11 there are openings 40 for the connections 42 and 43 of an oil cooler 44. An opening 45 is provided in the wall 32 for receiving a coolant outlet connection 46. In addition, the wall 32 has a threaded connector 47 and a shut-off element 48. Two caps 50, 51 are welded or otherwise attached to the ends of the manifold 11.

Der Ölkühler 44 ist durch eine stranggepreßte innere Querwand 52, die unteren Enden 31 α, 32 α der Seitenwände 31, 32 und durch die untere Wand 30 gebildet. Zum besseren Wärmetausch ist die Querwand 52 mit Rippen 53 versehen. Infolge der Abteilung durch die Querwand 52 werden sowohl die Kosten und Einbauschwierigkeiten eines getrennten Ölkühlers im unteren Verteiler als auch Undichtheiten sowie Verschmutzung des Kühlmittels und/ oder des Öls im wesentlichen vermieden.The oil cooler 44 is through an extruded inner transverse wall 52, the lower ends 31 α, 32 α of the side walls 31, 32 and formed by the lower wall 30. The bulkhead is for better heat exchange 52 provided with ribs 53. As a result of the division through the transverse wall 52, both the Costs and installation difficulties of a separate oil cooler in the lower distributor as well as leaks and contamination of the coolant and / or the oil is essentially avoided.

Die verhältnismäßig flachen Rohre 12 sind an ihren beiden Enden rechteckförmig erweitert und weisen die Öffnungen 54, 55 auf. Die öffnung 54 ist somit von den Seitenwänden 54 a, 54 b und Stirnwänden 54 c, 54 d gebildet. Beim Zusammenbau des Wärmetauschers sind die Stirnwände Seite an Seite gesetzt, und die Seitenwände 54 a, 54 b kommen in Anlage an die Längslappen 17 a und 17 b. Die Be rührungsflächen der Rohrenden miteinander und mit den Längslappen 17 a, 17 b sind verschweißt oder sonstwie miteinander verbunden. Die unteren Enden der Rohre 12 sind im Schlitz 38 in gleicher Weise aufgebaut.The relatively flat tubes 12 are widened in a rectangular manner at their two ends and have the openings 54, 55. The opening 54 is thus formed by the side walls 54 a, 54 b and end walls 54 c, 54 d . When assembling the heat exchanger, the end walls are placed side by side, and the side walls 54 a, 54 b come into contact with the longitudinal tabs 17 a and 17 b. Be the contact surfaces of the pipe ends with each other and with the longitudinal tabs 17 a, 17 b are welded or otherwise connected to each other. The lower ends of the tubes 12 are constructed in the same way in the slot 38.

Zwei Platten 56, 57 sind jeweils an die Sperrleisten 20, 21; 36, 37 angeschweißt, um die äußersten Blechrippen 13 des Wärmetauschers zu stützen.Two plates 56, 57 are each attached to the locking strips 20, 21; 36, 37 welded to the outermost sheet metal ribs 13 of the heat exchanger.
