Abstract
Die Erfindung betrifft einen Lamellenwärmeübertrager, umfassend ein ein Wärmeträgermedium führendes Rohrelement (1), das von einer Vielzahl in Rohrhauptachsrichtung hintereinander angeordneten Lamellenelementen (2) umschlossen ausgebildet ist. Nach der Erfindung ist vorgesehen, dass das Rohrelement (1) einstückig ausgebildet ist und in Rohrhauptachsrichtung mindestens eine von den Lamellenelementen (2) freigestellte Krümmung (3) aufweist.The invention relates to a laminated heat exchanger, comprising a heat transfer medium leading pipe element (1) which is formed by a plurality in Rohrhauptachsrichtung successively arranged fin elements (2) enclosed. According to the invention it is provided that the tubular element (1) is formed in one piece and in Rohrhauptachsrichtung at least one of the lamellar elements (2) exempted curvature (3).
Description
Die Erfindung betrifft einen Lamellenwärmeübertrager gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a laminated heat exchanger according to the preamble of
Ein Lamellenwärmeübertrager der eingangs genannten Art ist nach der
Der Erfindung liegt die Aufgabe zugrunde, einen Lamellenwärmeübertrager der eingangs genannten Art zu verbessern.The invention has the object to improve a laminated heat exchanger of the type mentioned.
Diese Aufgabe ist mit einem Lamellenwärmeübertrager der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst.This object is achieved with a laminated heat exchanger of the type mentioned by the features listed in the characterizing part of
Nach der Erfindung ist also vorgesehen, dass das Rohrelement einstückig ausgebildet ist und in Rohrhauptachsrichtung mindestens eine von den Lamellenelementen freigestellte Krümmung aufweist.According to the invention, it is thus provided that the tube element is formed in one piece and has at least one curvature exempted from the lamellar elements in the tube main axis direction.
Mit anderen Worten zeichnet sich die Erfindung gemäß einer ersten Alternative dadurch aus, dass zur Herstellung des Lamellenwärmeübertragers das durchgängige bzw. einstückige Rohrelement zunächst vollständig mit Lamellenelementen versehen wird und dass dann an den Stellen, an denen Krümmungen vorgesehen werden sollen, die Lamellenelement wieder entfernt werden.In other words, the invention is characterized according to a first alternative in that for the manufacture of the plate heat exchanger, the continuous or one-piece pipe element is initially completely provided with lamellar elements and that then at the points where curvatures are to be provided, the lamellar element are removed again ,
Besonders bevorzugt ist dabei vorgesehen, dass die Lamellenelemente wahlweise direkt aus dem Rohrelement oder aus einem das Rohrelement umschließenden Grundkörper herausgewalzt ausgebildet sind. Unter ”freistellen” im anspruchsgemäßen Sinne ist dabei zu verstehen, dass nach dem Walzen der Lamellenelemente ein Teil der Lamellenelemente zum Beispiel durch spanende Bearbeitung vom Rohrelement entfernt wird, so dass dieses in diesem Bereich nach außen ”freiliegt” und dementsprechend gut gebogen werden kann.Particularly preferably, it is provided that the lamellar elements are optionally rolled out directly from the tubular element or from a basic body enclosing the tubular element. The term "cut-off" in the sense of the claim is to be understood that after rolling the lamellar elements, a part of the lamellar elements is removed, for example, by machining from the pipe element, so that this "exposed" in this area to the outside and can be bent accordingly well.
Nach einer weiteren, ebenfalls vom Patentanspruch 1 umfassten Alternative ist das einstückige Rohrelement von vornherein nur an den Stellen mit zusätzlichem Werkstoff versehen, an denen später tatsächlich die Lamellenelemente ausgeformt werden. In diesem Fall entfällt die erwähnte spanende Bearbeitung gemäß der ersten Alternative, da im Bereich der freigestellten Krümmung mangels Werkstoff ohnehin keine Lamellenelemente vorhanden sind.According to another, also encompassed by
Bei der bevorzugten Lösung mit dem zusätzlichen Grundkörper besteht der Lamellenwärmeübertrager dabei aus einem ersten, inneren Rohrelement, über das ein zweites, äußeres Rohrelement geschoben ist. Dieses zweite, den Grundkörper bildende Rohrelement wird zur Erzeugung der Lamellenelemente einem Walzprozess unterworfen, so dass dann ein Lamellenwärmeübertrager vorliegt, bei dem die aus dem Grundkörper herausgewalzten Lamellenelemente das innere Rohrelement umschließend ausgebildet sind.In the preferred solution with the additional base body of the fin heat exchanger consists of a first, inner tube member, over which a second, outer tube member is pushed. This second, the main body forming tubular element is subjected to a rolling process to produce the lamellar elements, so that then there is a fin heat exchanger, in which the rolled out of the main body lamellar elements, the inner tube member are formed enclosing.
Die erfindungsgemäße Maßgabe lässt sich ferner besonders gut dadurch realisieren, dass das innere Rohrelement aus Stahl, vorzugsweise Edelstahl, gebildet ist, während das äußere, den Grundkörper bildende Rohrelement aus einem weicheren Material, wie zum Beispiel Aluminium, besteht. Beim Walzprozess kann dabei vorgesehen sein, im Inneren des ersten Rohrelements im Bereich der aktuellen, äußeren Walzstelle einen Dorn zur Wandunterstützung zu führen.The proviso according to the invention can also be realized particularly well in that the inner tubular element is made of steel, preferably stainless steel, while the outer tubular element forming the main body consists of a softer material, such as aluminum. In the rolling process can be provided to lead a mandrel for wall support in the interior of the first tubular element in the region of the current, outer rolling point.
Wie weiterhin ersichtlich, ist die erfindungsgemäße Maßgabe besonders gut bei einer Konstruktion aus zwei Rohrelementen bzw. einem Rohrelement und einem Grundkörper möglich, wobei sie darüber hinaus die Option schafft, einen Lamellenwärmeübertrager zu bilden, der aus einer Reihe von ”mäanderförmig” angeordneten Teilabschnitten gebildet ist. Dies wird weiter unten nochmals ausführlich erläutert.As can further be seen, the proviso according to the invention is particularly well-suited for a construction comprising two pipe elements or a pipe element and a base body, and moreover it creates the option of forming a lamella heat exchanger which is formed from a series of "meandering" arranged sections , This will be explained again in detail below.

Andere vorteilhafte Weiterbildungen des erfindungsgemäßen Lamellenwärmeübertragers ergeben sich aus den abhängigen Patentansprüchen.Other advantageous developments of the laminated heat exchanger according to the invention will become apparent from the dependent claims.
