Description

VERFAHREN ZUR HERSTELLUNG VON WÄRMETAUSCHERN, INSBESONDERE VON WÄRMETAUSCHERN PUR DIE FAHRZEUGINDUSTRIE, AUS ALUMINIUM- ODER LEGIERTEN ALUMINIUMPLATTEN METHOD FOR THE PRODUCTION OF HEAT EXCHANGERS, IN PARTICULAR HEAT EXCHANGERS FROM THE VEHICLE INDUSTRY, FROM ALUMINUM OR ALLOY ALUMINUM PLATES
Die Erfindung betrifft ein Verfahren zur Herstellung von Wärmetauschern aus Aluminium- oder legierten Aluminiumplatten, hauptsächlich zur Anwendung als Fahrzeugkühler.The invention relates to a method for producing heat exchangers from aluminum or alloy aluminum plates, mainly for use as a vehicle radiator.
Die Aufgabe der verschiedenen Kühlersysteme liegt darin, daß sie aus der Umgebung der Wärmeentwicklung (z.B. aus dem Brennraum von Motoren) die überflüssige Wärme entfernen, unter anderem deshalb, damit der Wärmezustand der Bestandteile und der Schmierstoffe des Motors auf einem konstanten Niveau bleibt, und dadurch eine Temperatur der der Wärmebβanspruchung ausgesetzten Bestandteile erzielt wird, die hinsichtlich der Wirtschaftlichkeit, Energetik und Verschleiß beständigkeit gleicherweise optimal ist.The task of the various radiator systems is that they remove the superfluous heat from the surroundings of heat development (e.g. from the combustion chamber of engines), among other things, so that the thermal state of the components and the lubricants of the engine remain at a constant level, and thereby a temperature of the components exposed to thermal stress is achieved, which is equally optimal in terms of economy, energy and wear resistance.
Der Grundstoff der Wärmetauscher, bzw. der Kühler der Fahrzeuge war lange Zeit das Kupfer. In der letzten Zeit begann eine Entwicklung mit zwei Richtungen: einerseits wird die Erhöhung der auf das Einheitsvolumen des Kühlers fallenden Wärmemenge, z.B. durch die Vergrößerung der Wärmetausohflächen, angestrebt, andererseits ist man zwecks der Energieersparung, bzw. des Umweltschutzes bestrebt das Gewicht der PKW-s durch die Anwendung von Aluminiumkühlern kleineren Gewichts zu vermindern. Das Aluminium ist nämlich leichter und billiger als das Kupfer, und gleichzeitig ist es leichter und von besserer Wärmeleitungefähigkeit als der Stahl. Die Anwendungsverbreitung von Aluminiuu begann bei den Wärmetauschern der Fahrzeugindustrie nur in den letzten Zeiten, obwohl bei den Luftfahrzeugen sohon nach dem II. Weltkrieg einige, die Anforderungen der Gewiohtverminderung befriedigende Konstruktionen aus Leichtmetall erschienen. Diese Kühlsysteme konnten sich aber bei den Straßenfahrzeugen gegenüber den aus Kupfer hergestellten Lösungen noch nicht durchsetzen, was hauptsächlich technologische Gründe hatte, z.B. die Tatsache, daß das Aluminium nicht gelötet werden konnte. Letzten Endes wurden die bei den Schienenfahrzeugen verwirklichten Aluminium-Kühlsysteme auch für die Straßenfahrseugen angewendet. Bei diesen mit den aus Kupfer hergestellten Kühlern analogen Lösungen sind der untere und der obere Wassersammler durch Verbindungsrohre, durch sogenannte Wasserrohre verbunden. Die Wassersammler können aus Aluminium oder Plasten hergestellt werden. Die die Wassersammler verbindenden Aluminium-Wasserrohre können nach dem Stand der Technik durch die folgenden Verfahren hergestellt werden:The base material of the heat exchangers and the radiator of the vehicles was copper for a long time. In recent times, development has started in two directions: on the one hand, the aim is to increase the amount of heat falling on the unit volume of the radiator, for example by increasing the heat exchange area, on the other hand, in order to save energy and protect the environment, s reduce by using aluminum coolers of smaller weight. This is because aluminum is lighter and cheaper than copper, and at the same time it is lighter and has better thermal conductivity than steel. The use of aluminum in the heat exchangers of the automotive industry has only begun in recent times, although in the aircraft after World War II some light metal structures satisfying the requirements for reducing the weight appeared. However, these cooling systems have not yet been able to assert themselves in road vehicles over solutions made from copper, which was mainly due to technological reasons, for example the fact that the aluminum could not be soldered. In the end, the aluminum cooling systems implemented in the rail vehicles were also used for road vehicles. In these solutions, which are analogous to those made of copper, the lower and the upper water collector are connected by connecting pipes, so-called water pipes. The water collectors can be made of aluminum or plastic. The aluminum water pipes connecting the water collectors can be produced according to the prior art by the following processes:
- durch Verwalzen von zwei Aluotiniumbändern, danach durch das Aufblasen der Wasserrohre durch Wasserdruck;- by rolling two aluminum strips, then by inflating the water pipes by water pressure;
- durch Pressen und durch nachfolgenden Zug aus einem Aluminiumrohr; - aus einem Band durch Verfalzung.- by pressing and by subsequent pull from an aluminum tube; - from a band by folding.
Von den genannten Lösungen hat das Aufbaasen der Wasserrohre durch Wasserdruck den Nachteil, daß danach aus den Wasserrohre das Wasser verdampft werden muss, und bei den Wasserrohren mit verschiedenen Querschnitten teure Hilfswerkzeuge angewendet werden müssen. Die Herstellung der aus einem Band durch Verfalzung gefertigten Wasserrohre ist sehr arbeitsaufwändig, und das als zweites genannte Verfahren ist auch nicht weniger kompliziert. Zu den so hergestellten Wasserrohren werden die Kühler-oberfläche erhöhende Lamellen mit mechanischer Verbindung oder durch Löten befestigt.Of the above-mentioned solutions, the building up of the water pipes by water pressure has the disadvantage that the water must then be evaporated from the water pipes, and expensive auxiliary tools must be used for the water pipes with different cross sections. The production of the water pipes made from a band by interlocking is very labor-intensive, and the second method mentioned is also no less complicated. The radiator surface-increasing fins are attached to the water pipes produced in this way with mechanical connection or by soldering.
Die Aufgabe der Erfindung ist die Ausarbeitung eines Verfahrens, das die Herstellung von Wärmetausohern aus Aluminium- oder legierten Aluminiumplatten wesent lieh vereinfacht und beschleunigt, und dadurch eine produktive und billige Massenproduktion ermöglicht.The object of the invention is to elaborate a method which substantially simplifies and accelerates the production of heat exchangers from aluminum or alloyed aluminum plates, and thereby enables productive and cheap mass production.
Der Erfindung liegt die Erkenntnis zugrunde, daß die einzelnen Glieder des Wärmetauschers auch aus zwei zusammenfallenden Teilen angefertigt werden können, falls die Verbindung der zwei Teile durch ein billi ges und schnelles Verfahren durchgeführt werden kann. Dieses letztere wird hauptsächlich durch die Erkenntnis der Möglichkeit der Aluainium-Lötung, sowie durch das Erscheinen von neuen Klebstoffen gewährt.The invention is based on the knowledge that the individual elements of the heat exchanger can also be made from two coincident parts if the connection of the two parts can be carried out by a cheap and fast method. The latter is mainly granted through the knowledge of the possibility of aluminum soldering, as well as through the appearance of new adhesives.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß in die als Grundstoff des Wärmetausohers dienende Aluminium- oder legierte Aluminiumplatte unteren und oberen Flüssigkeitssammler, sowie wenigstens ein diese verbindendes Verbindungsrohr bildender, zusammenhängender Hohlraum gepresst wird, zwei so ausgestalteten Pressstücke mit ihren hohlen Seiten einander gegenübergestellt mit einer unlösbaren Verbindung zu einem Wärmetausoherglied verbunden werden, und die einzelnen Wärmetausoherglieder längs der Seitenfläche ihrer Flüssigkeitssammler ebenfalls mit unlösbarer Verbindung miteinander befestigt werden.The object is achieved according to the invention in that the lower and upper liquid collector serving as the base material of the heat exchanger and the aluminum or alloy aluminum plate, as well as at least one connecting cavity forming this connecting tube, are pressed, two pressed pieces configured in this way with their hollow sides facing each other with an inseparable connection are connected to a heat exchanger member, and the individual heat exchanger members are also fastened to one another along the side surface of their liquid collector with an inseparable connection.
Die die einzelnen Wärmetausoherglieder bildenden Pressstücke werden erfindungsgemäß zweckmäßigerweise miteinander verlötet, aber die Verbindung der Pressstücke kann gegebenfalls auch durch Kleben durchgeführt werden. Nach einer zweckmäßigen Auβführungsweise der Erfindung werden die Oberflächen der Verbindungsrohre beim Pressen mit einer die Oberfläche vergrössernden Verrippung ausgebildet.According to the invention, the press pieces forming the individual heat exchanger members are expediently soldered to one another, but the connection of the press pieces can may also be carried out by gluing. According to an expedient embodiment of the invention, the surfaces of the connecting pipes during the pressing are formed with ribbing which increases the surface area.
Nach einer weiteren Auaführungsweise der Erfindung werden zwei gleichförmige Pressstücke mit ihren hohlen Seiten einander gegenübergestellt, doch in einer im Vergleich zueinander um 180° verdrehten Lage miteinander befestigt. Diese Lösung wird z.B. dann angewendet, wenn die Oberfläche der Rohrleitungen eine Wellenlinie beschreibt.According to a further embodiment of the invention, two uniform pressing pieces are juxtaposed with their hollow sides, but are fastened to one another in a position rotated by 180 ° relative to one another. This solution is e.g. used when the surface of the pipeline describes a wavy line.
Die oben beschriebenen Wärmetauscherglieder werden erfindungsgemäß miteinander verklebt. Es ist auch eine solche Lösung vorstellbar, daß die Verbindung der Wärmetauscherglieder unter Anwendung von einem Lot mit einem Schmelzpunkt abweichend vom zur Verbindung von Pressstücken benutzten Lot durchgeführt wird.The heat exchanger members described above are glued together according to the invention. Such a solution is also conceivable that the connection of the heat exchanger elements is carried out using a solder with a melting point different from the solder used for connecting press pieces.
Die Erfindung wird anhand der Zeichnung näher erläutert. Es zeigenThe invention is explained in more detail with reference to the drawing. Show it

Wie es aus der Fig. 1 ersichtlich ist, bilden bei dem erfindungsgemäß hergestellten Wärmetauscherglied die oberen und unteren Flüssigkeitssammler 1 und 2 mit dem diese Teile verbindenden Verbindungsrohr 3 einen zu sammenhängenden Hohlraum, der in einem Arbeitsvorgang in eine Aluminium- oder legierte Aluainiuoplatte oder in ein Aluminiumband gepresst wird. Aus den nicht ge pressten Kanten der Platte werden Lamellen 4 gebildet. Das so ausgestaltete Pressstück wird längs der Fläche der Lamellen 4 mit einem anderen Pressstück von ähnlicher Ausbildung zusammengelötet, und zwar zweckmäßiger weise so, daß die beiden Pressstücke mit ihren hohlen Seiten einander gegenübergestellt in einer im Vergleich zueinander um 180° verdrehten Lage verbunden werden. Auf diese Weise werden Wärmetausoherglieder 5 erhöhter Kühlfläche hergestellt, die wellenförmige Verbindungsrohre 3 sowie auf dem oberen und unteren Teil jeweils einen eigenen Flüssigkeitssammler aufweisen, wie es aus Fig. 2 ersichtlich ist. Die Verbindungsrohre 3 können auch gerade sein.Fig. 3 is a top view of the construction shown in Fig. 2. As can be seen from FIG. 1, in the heat exchanger element produced according to the invention, the upper and lower liquid collectors 1 and 2 form a coherent cavity with the connecting pipe 3 connecting these parts, which in one work process can be made into an aluminum or alloyed aluminum plate or into one Aluminum strip is pressed. Lamellae 4 are formed from the non-pressed edges of the plate. The press piece designed in this way is soldered along the surface of the fins 4 to another press piece of a similar design, and expediently so that the two press pieces are connected with their hollow sides opposite one another in a position rotated by 180 ° relative to one another. In this way, heat exchanger elements 5 with an increased cooling surface are produced, the corrugated connecting tubes 3 and on the upper and lower part each have their own liquid collector, as can be seen from FIG. 2. The connecting pipes 3 can also be straight.
Die an einander gereihten Wärmetauscherglieder 5 nach oben beschriebener Art ergeben den vollen Umfang des Wärmetauschers.The lined up heat exchanger elements 5 according to the type described above give the full scope of the heat exchanger.
Die einzelnen Wärmetausoherglieder 5 werden miteinander längs der Seitenfläche 6 der Flüssigkeitssammler 1, 2, zweckmäßigerweise durch Kleben, eventuell durch Löten verbunden. Die unteren und oberen Flüssigkeitssammlerräume der einzelnen Wärmetauscherglieder 5 sind auf ihren beiden Seitenflächen 6 mit Öffnungen versehen, wodurch die Kühlflüssigkeit 7 durch die Wärmetauscherglieder 5 strömen kann. In Fig. 3 ist die Strömungsrichtung der durch die Wärmetauscherglieder strömenden Luft mit der Bezugsnummer 8 bezeichnet.The individual heat exchanger elements 5 are connected to one another along the side surface 6 of the liquid collector 1, 2, expediently by gluing, possibly by soldering. The lower and upper liquid collector spaces of the individual heat exchanger elements 5 are provided with openings on their two side surfaces 6, as a result of which the cooling liquid 7 can flow through the heat exchanger elements 5. In Fig. 3, the direction of flow of the air flowing through the heat exchanger members is designated by the reference number 8.
Die anschließenden Aus- und Einlasa-, bzw. anderenThe subsequent exhaust and Einlasa-, or others
Stutzen können zweckmäßigerweise durch Kleben oder eventuell durch Löten zur Seitenfläche der Wärmetauscherelemente befestigt werden. Die so ausgestalteten Wärmetauscher können schon mit dem bekannten Rahmen zuaammengefaßt werden, damit sie als Kühler zu dem entsprechenden Teil eines PKW-s befestigt werden können.Sockets can expediently be attached to the side surface of the heat exchanger elements by gluing or possibly by soldering. The heat exchangers designed in this way can already be combined with the known frame so that they can be attached to the corresponding part of a car as a cooler.
Der größte Vorteil der Wärmetauscher von solcher Ausbildung liegt - im Gegensatz zu den bekannten Lösungen - im Ersparen von menschlicher Arbeitskraft und in der Automatisierbarkeit der Produktion. Auch ihr Wirkungsgrad ist besser, weil sich bei den Anschlußstellen der Lamellen und der Verbindungsrohre kein Verlust ergibt.The greatest advantage of heat exchangers of this type of training - in contrast to the known solutions - is the saving of human labor and the automation of the production. Their efficiency is also better because there is no loss in the connection points of the fins and the connecting pipes.
Die erfindungsgemäß hergestellten Wärmetauscher können außer der Fahrzeugindustrie (Kühlung von PKW-s, Lastwagen, Autobussen, Motorwagen, landwirtschaftliehen Fahrzeugen) noch für Ölkühler von elektrischen Transformatoren, Tiefkühler von Kühlschränken, Kalorifer usw. verwendet werden. In addition to the automotive industry (cooling of passenger cars, trucks, buses, motor vehicles, agricultural vehicles), the heat exchangers produced according to the invention can also be used for oil coolers for electrical transformers, freezers for refrigerators, calorifers, etc.
