Description

Die vorliegende Erfindung betrifft ein Verfahren zur Her­stellung eines Wärmetauschers, bei welchem mindestens zwei im Wärmeaustausch stehende Strömungsmittel in, zwischen den Windungen von spiralförmig ineinandergewickelten Bandmate­rialien gebildeten Strömungskanälen geführt werden, die sich in radialer Richtung des Gesamtkörpers jeweils abwechseln, wobei die Wärmeübertragung in radialer Richtung durch das Bandmaterial des spiralförmigen Körpers erfolgt.The present invention relates to a method for producing a heat exchanger, in which at least two fluids in heat exchange are guided in flow channels formed between the turns of spirally interwoven band materials, which alternate in the radial direction of the entire body, the heat transfer being carried out in the radial direction the band material of the spiral body is made.

Wärmetauscher in sogenannter Spiralbauart mit einer Strömung der strömungsfähigen Wärmeaustauschmittel in Umfangsrichtung sind zwar bekannt, konnten sich aber bisher nur wenig durch­setzen, da sich deren Herstellung als sehr kompliziert und somit teuer erwiesen hat.Heat exchangers in a so-called spiral type with a flow of the flowable heat exchange means in the circumferential direction are known, but have so far been largely unsuccessful, since their production has proven to be very complicated and therefore expensive.

Es ist daher Aufgabe der vorliegenden Erfindung, ein Ver­fahren zu schaffen, das eine vergleichsweise unkomplizierte und preisgünstige Herstellung von Wärmetauschern der ge­ nannten Art gestattet.It is therefore an object of the present invention to provide a method which enables a comparatively uncomplicated and inexpensive production of heat exchangers named type allowed.

Ein solches Verfahren zeichnet sich erfindungsgemäss da­durch aus, dass die Bandmaterialien an einem, axiale Kanal­anschlüsse aufweisenden Innenkörper abgestützt und dort, vor­zugsweise auf einer Bandwickelmaschine, zusammen mit rand­nahen bzw. stirnseitigen Distanz- und Seitenbegrenzungs­profilen aufgewickelt und randnahe miteinander gas- bzw. flüssigkeitsdicht verbunden werden.Such a method is characterized according to the invention in that the strip materials are supported on an inner body having axial channel connections and are wound up there, preferably on a strip winding machine, together with edge and end-side distance and side boundary profiles and connected gas-tight or liquid-tight to one another near the edge.

Durch diese Massnahmen ist es nunmehr möglich, Wärmetauscher der vorgenannten Art auf rationellste Weise herzustellen, wobei diese Massnahmen einen grossen Spielraum bezüglich Anzahl Strömungskanäle pro Windung, Durchtrittsquerschnitt der Kanäle, axialer Erstreckung und Anzahl Windungen u.a. ge­statten, was eine unmittelbare Anpassung solcherart herge­stellter Wärmetauscher an die unterschiedlichsten Betriebs­bedingungen ermöglicht.Through these measures, it is now possible to manufacture heat exchangers of the aforementioned type in the most rational manner, these measures providing a large scope in terms of the number of flow channels per turn, passage cross section of the channels, axial extension and number of turns, etc. allow, which enables a direct adaptation of heat exchangers manufactured in this way to a wide variety of operating conditions.

Ein nach dem erfindungsgemässen Verfahren hergestellter Wärmetauscher kann sowohl in Gleichstrom als auch in Gegen­strom betrieben werden.A heat exchanger produced by the method according to the invention can be operated both in cocurrent and in countercurrent.

Für einen optimalen Wärmeaustausch zwischen den Strömungs­mitteln ist ein allfälliger ungewollter Temperaturausgleich zu vermeiden, was dadurch erreicht wird, dass die gemeinsam in einer Windung in Wärmekommunikation liegenden Strömungs­kanalabschnitte von jeweils jenen der folgenden Windungen durch Wärmeisolation getrennt werden.An unwanted temperature compensation is necessary for an optimal heat exchange between the fluids to avoid what is achieved in that the flow channel sections lying together in one turn in thermal communication are separated from those of the following turns by thermal insulation.

Hierfür kann für die Wärmeisolation ein Band aus einem wärme­isolierenden Material mit eingewickelt oder als windungs­äusseres Bandmaterial ein Band aus einem wärmeisolierenden Material oder mit einer wärmeisolierenden Beschichtung ver­wendet werden.For this purpose, a tape made of a heat-insulating material can be wrapped for the thermal insulation or a tape made of a heat-insulating material or with a heat-insulating coating can be used as the outer winding material.

Eine rationelle Aufwicklung lässt sich dabei erreichen, wenn mindestens eines der Distanz- und Seitenbegrenzungs­profile vor dem Ineinanderwickeln mittels seitlichem Längs­schlitz auf die Aussenkante des zugeordneten Bandmaterials aufgesteckt wird.A rational winding can be achieved if at least one of the spacer and side delimitation profiles is slipped onto the outer edge of the assigned strip material by means of a lateral longitudinal slot before being wound into one another.

Um die Anordnung stirnseitig gas- bzw. flüssigkeitsdicht zu verschliessen, kann in Abhängigkeit der verwendeten Mate­rialien ein Kleben, Schweissen, Verschmelzen oder Löten infrage kommen. Die hierfür verwendeten Wärmeköpfe einer Schweissmaschine oder dgl. werden dann zweckmässig entlang einer den stirnseitigen Wickelkanten entsprechenden Pilot­linie geführt.In order to close the arrangement gas-tight or liquid-tight on the end face, depending on the materials used, gluing, welding, melting or soldering can be considered. The heat heads used for this purpose of a welding machine or the like are then expediently guided along a pilot line corresponding to the end winding edges.

Ferner betrifft die vorliegende Erfindung einen nach dem erfindungsgemässen Verfahren hergestellten Wärmetauscher. Dieser zeichnet sich dann zweckmässig aus durch mindestens zwei, von spiralförmig ineinandergewickelten Bandmaterialien sowie randnahen bzw. stirnseitigen, miteingewickelten und mit den Bandmaterialien gas- bzw. flüssigkeitsdicht ver­bundenen Distanz- und Seitenbegrenzungsprofilen begrenzte Strömungskanäle, welche an beiden Enden in Zuleitungsrohre vorzugsweise stirnseitig der Anordnung ausmünden, wobei die gemeinsam in einer Windung in Wärmekommunikation liegenden Strömungskanalabschnitte von jeweils jenen der folgenden Windungen durch eine Wärmeisolation getrennt sind und die ganze Anordnung von einer wärmeisolierenden Ummantelung um­geben ist.The present invention further relates to a heat exchanger produced by the method according to the invention. This is then expediently characterized by at least two flow channels which are spirally interwoven band materials and edge-side or end-side, co-wound and gas-tight and liquid-tightly connected distance and side limitation profiles which are connected at both ends in supply pipes, preferably on the front side of the arrangement, wherein the flow channel sections lying together in one turn in thermal communication are separated from those of the following turns by thermal insulation and the entire arrangement is surrounded by a heat-insulating jacket.

For example, embodiments of the subject matter of the invention are explained in more detail below with reference to the drawing. Show it:
  • 1 in a diagrammatic cross section, in partial completion, an inventive heat exchanger for explaining the inventive method for its production;
  • FIG. 2 shows a finished heat exchanger according to FIG. 1 in a diagram-like partial section;
  • 3 to 5
    in a sectional sectional view, different design variants of the arrangement of interconnected band materials and distance and side boundary profiles; and
  • Fig. 6 is a diagrammatic representation of an embodiment variant of the heat exchanger according to the invention.

Gemäss Fig. l umfasst der hier in einer Herstellungsphase gezeigte Wärmetauscher einen achsenparallel stufenförmig abgesetzten länglichen Innenkörper l von hier angenähert ovalem Querschnitt, auf dessen Stufe l' übereinander zwei flache, stirnseitig herausragende (Fig. 2) Zuleitungsrohre 2 und 2' aufgesetzt sind. In diese Zuleitungsrohre 2 und 2' münden spiralförmige Strömungskanäle l4 bzw. l4' ein, die in Umfangsrichtung durch zwei spiralförmig ineinanderge­wickelte Bandmaterialien 4 bzw. 4' und radial durch randnahe bzw. stirnseitige miteingewickelte Distanz- und Seitenbe­grenzungsprofile 6 begrenzt sind. Die Herstellung erfolgt dabei vorzugsweise auf einer, sonst für die Herstellung von elektrischen Spulen verwendeten Bandwickelmaschine, der die Bandmaterialien und die Distanz- und Seitenbegrenzungsprofile kontinuierlich über Umlenkrollen von Vorratsrollen zugeführt werden (nicht näher veranschaulicht, da bekannt).According to FIG. 1, the heat exchanger shown here in a manufacturing phase comprises an elongated inner body 1, which is stepped in parallel to the axis and has an approximately oval cross-section, on the step 1 'of which two flat, protruding (FIG. 2) supply pipes 2 and 2' are placed one above the other. In these supply pipes 2 and 2 'open spiral flow channels l4 and l4', which are delimited in the circumferential direction by two spirally wound strip materials 4 and 4 'and radially by edge and end side co-wound distance and side limitation profiles 6. The production is preferably carried out on a tape winding machine that is otherwise used for the production of electrical coils Strip materials and the distance and side limitation profiles are fed continuously via deflection rollers from supply rollers (not illustrated in detail since they are known).

Hierbei erfolgt das Aufwickeln der Bandmaterialien und der Distanz- und Seitenbegrenzungsprofile gleichzeitig. Zudem ist es vorteilhaft, wenn dann gleichzeitig auch eine gas- ­bzw. flüssigkeitsdichte Verbindung zwischen den Bandmateri­alien und den Randprofilen hergestellt wird. Hierfür können nicht näher gezeigte Wärmeköpfe einer Schweissmaschine oder dgl. entlang einer den stirnseitigen Wickelkanten entsprechen­de Pilotlinie geführt werden.The strip materials and the distance and side limitation profiles are wound up simultaneously. In addition, it is advantageous if a gas or liquid-tight connection between the strip materials and the edge profiles is established. For this purpose, heat heads (not shown in detail) of a welding machine or the like can be guided along a pilot line corresponding to the end winding edges.

Um einen unerwünschten Wärmeaustausch zwischen den Strömungs­kanalabschnitten unterschiedlicher Windungen zu verhindern, werden die Windungen durch eine Wärmeisolation getrennt, welche gemäss Fig. l in Form eines Isoliermaterialbandes 8 als windungsinnerstes Band mit eingewickelt wird. Damit kann ein Wärmeaustausch in allen Windungen nur zwischen den Strömungskanälen l4 und l4' der betreffenden Windung statt­finden.In order to prevent undesired heat exchange between the flow channel sections of different windings, the windings are separated by a heat insulation which, according to FIG. This means that heat can only be exchanged in all turns between the flow channels 14 and 14 'of the turn in question.

Die gleiche Wirkung wird erreicht, wenn das windungsäussere Bandmaterial 4 selbst aus einem wärmeisolierenden Material besteht oder mit einer wärmeisolierenden Beschichtung ver­ sehen ist.The same effect is achieved if the outer band material 4 itself consists of a heat-insulating material or with a heat-insulating coating see is.

Fig. 2 zeigt, dass der so gewickelte Wärmetauscher dann durch zwei weitere, abschliessende Zuleitungsrohre l2 und l2' er­gänzt und das Ganze noch mit einer wärmeisolierenden Ummante­lung 9 versehen wird.FIG. 2 shows that the heat exchanger wound in this way is then supplemented by two further, final supply pipes l2 and l2 'and the whole is still provided with a heat-insulating jacket 9.

Die hier kastenförmigen Zuleitungsrohre 2,2',l2 und l2' ragen achsenparallel an der gleichen Stirnseite heraus.The box-shaped supply pipes 2,2 ', l2 and l2' protrude parallel to the axis on the same end face.

Alternativ können die Zuleitungsrohre auch wechselseitig an­geordnet sein, wie das Fig. 6 zeigt. Hier sind zudem die Zuleitungsrohre 2,2' und l2,l2' von rundem Querschnitt. Zudem ist hier der Wärmetauscher in runder Form gewickelt.Alternatively, the feed pipes can also be arranged alternately, as shown in FIG. 6. In addition, the feed pipes 2, 2 'and l2, l2' have a round cross section. In addition, the heat exchanger is wrapped in a round shape.

Fig. 3 veranschaulicht, dass die Distanz- und Seitenbegren­zungsprofile 6 vor dem Ineinanderwickeln mittels seitlichem Längsschlitz 6' auf die Aussenkante des zugeordneten Band­materials 4 bzw. 4' aufgesteckt werden.FIG. 3 illustrates that the distance and side delimitation profiles 6 are plugged onto the outer edge of the assigned strip material 4 or 4 'by means of a longitudinal longitudinal slot 6' before being wound into one another.

Alternativ können aber auch die Bandmaterialien 4 bzw. 4' wechselweise in die Längsschlitze 6' der Profile 6 eingrei­fen bzw. zwischen sich radial folgende Profile 6 eingelegt (Fig. 4) oder, gemäss Fig. 5, das Ganze schichtförmig auf­gebaut sein.Alternatively, however, the strip materials 4 or 4 'can alternately engage in the longitudinal slots 6' of the profiles 6 or be inserted between the radially following profiles 6 (FIG. 4) or, according to FIG. 5, the whole may be constructed in layers.

Anstelle der dargestellten im Querschnitt rechteckförmigen Profile 6 können diese auch einen anderen geeigneten Quer­schnitt aufweisen.Instead of the profiles 6, which are rectangular in cross section, they can also have another suitable cross section.

Die Materialien des erfindungsgemässen Wärmetauschers können natürlich beliebig sein, soweit diese überhaupt geeignet sind.The materials of the heat exchanger according to the invention can, of course, be as long as they are suitable at all.

Ferner kann ein solches Wärmetauschen im Gleichstrom oder Gegenstrom mit den unterschiedlichsten Strömungsmitteln betrieben werden.Such a heat exchange can also be carried out in cocurrent or countercurrent with a wide variety of fluids.

Selbstverständlich beschränken sich das Verfahren und der nach dem Verfahren hergestellte Wärmetauscher nicht auf die vorbeschriebenen Ausführungsformen, sondern lassen im Rahmen der Erfindung weitere Modifikationen zu.Of course, the method and the heat exchanger produced by the method are not limited to the above-described embodiments, but allow further modifications within the scope of the invention.
