Description

Die vorliegende Erfindung bezieht sich auf einen Wärmetauscher für Flüssigkeiten gemäß dem Oberbegriff des Hauptanspruchs.The present invention relates to a heat exchanger for liquids according to the preamble of the main claim.

Solche Wärmetauscher werden recht vielfältig verwendet, beispielsweise in Umlaufwasserheizern zur Aufheizung von Gebrauchswasser im Durchlaufverfahren, bei Sonnenkollektoranlagen zum Aufheizen von Brauch- oder Speicherwasser durch das Fluid des Sonnenkollektors oder bei Wärmepumpen zum Beheizen des Umlaufwassers einer Heizungsanlage vom flüssigen Kältemittel.Such heat exchangers are used in a wide variety of ways, for example in circulating water heaters for heating process water in a continuous process, in solar collector systems for heating service water or storage water through the fluid of the solar collector or in heat pumps for heating the circulating water of a heating system from liquid refrigerant.

Ausgeführte Beispiele solcher Wärmetauscher bestehen häufig aus Kupfergehäusen, in deren Inneres eine Rohrschlange aus Kupfer eingebraucht ist, die das eine Fluid führt, während in dem Raum zwischen Kupfergehäuse und äußerem Mantel der Rohrschlange das zweite Fluid geführt ist. Kupfer als Material für das Gehäuse kommt aber für viele aggressive Medien nicht in Frage.Executed examples of such heat exchangers often consist of copper housings, in the interior of which a pipe coil made of copper is used, which carries the one fluid, while the second fluid is guided in the space between the copper housing and the outer jacket of the pipe coil. However, copper as a material for the housing is out of the question for many aggressive media.

Aus der US-PS 3 880 226 ist ein Wärmetauscher im Rahmen eines Wasserqualitäts-Untersuchungssystems für ein dampfbetriebenes Elektrizitätserzeugungskraftwerk bekanntgeworden, der den Merkmalen des Oberbegriffs des unabhängigen Anspruchs entspricht. Hierbei ist im Rahmen eines Gehäuses eine Vielzahl von Rohren vorgesehen, die unabhängig voneinander Wasser oder erhitztes Wasser auf unterschiedlichen Temperaturen führen, wobei diese Rohre jeweils umgeben sind von Wasser, das in einer Vielzahl von Kanälen geführt ist, die von der Innenseite des Gehäuses einerseits und von den das andere Fluid führenden Rohren andererseits gebildet sind. Bei diesem Stand der Technik ist es vorgesehen, den Durchsatz der in den einzelnen Rohren geführten Fluide so einzustellen, daß sie alle auf die gleiche Austrittstemperatur vom Wasser heruntergekühlt werden. Eine Angleichung der Querschnitte zur Erzielung gleicher Wärmeübergangsströme in den einzelnen Pfaden des Wärmetauschers ist somit nicht vorgesehen.From US Pat. No. 3,880,226, a heat exchanger has become known in the context of a water quality inspection system for a steam-operated power generation plant, which corresponds to the features of the preamble of the independent claim. Here, in the context of a housing, a plurality of tubes are provided which independently carry water or heated water at different temperatures, these tubes being surrounded in each case by water which is guided in a plurality of channels which, on the one hand, and from the inside of the housing on the other hand, from which pipes carrying the other fluid are formed. In this prior art, it is provided that the throughput of the fluids guided in the individual tubes is adjusted so that they are all cooled down to the same outlet temperature by the water. An alignment of the cross sections to achieve the same heat transfer currents in the individual paths of the heat exchanger is therefore not provided.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen in der Leistung variierbaren Wärmeaustauscher zwischen zwei Fluidmedien zu schaffen, der einfachen Aufbau und Montage aufweist und einen guten Wärmeübergang zwischen den Medien gewährleistet.The present invention has for its object to provide a variable heat exchanger between two fluid media, which has a simple structure and assembly and ensures good heat transfer between the media.

Die Lösung dieser Aufgabe gelingt mit den kennzeichnenden Merkmalen des Hauptanspruchs.This problem is solved with the characterizing features of the main claim.

Weitere Ausgestaltungen und besonders vorteilhafte Weiterbildungen der Erfindung sind aus den Unteransprüchen sowie der nachfolgenden Beschreibung ersichtlich, die ein Ausführungsbeispiel der Erfindung näher erläutert.Further refinements and particularly advantageous developments of the invention can be seen from the subclaims and the following description, which explains an exemplary embodiment of the invention in more detail.

Es zeigen

  • Figur eins eine Querschnittsdarstellung des Wärmetauschers entlang einer Schnittlinie 1-1, die in der Figur zwei angegeben ist,
  • Figur zwei eine Ansicht von oben auf den Deckel des Wärmetauschers von Figur eins und
  • Figur drei ein Detail der Rohrdichtung aus Figur eins und Figur vier einen Querschnitt durch die Ebene der Figur 1.
Show it
  • FIG. 1 shows a cross-sectional illustration of the heat exchanger along a section line 1-1, which is indicated in FIG. 2,
  • Figure two is a top view of the lid of the heat exchanger of figure one and
  • Figure 3 shows a detail of the pipe seal from Figure one and Figure four shows a cross section through the plane of Figure 1.

In allen vier Figuren bedeuten gleiche Bezugszeichen jeweils die gleichen Einzelheiten.In all four figures, the same reference numerals denote the same details.

Der Wärmetauscher gemäß Figur eines besteht im wesentlichen aus einem Kanalblock 1, der im wesentlichen Quaderform besitzt und aus Kunststoff in einem Teil gespritzt ist. Er weist in einer Ebene im Querschnitt ringförmige, gleich große Kanäle 2 auf. Die Kanäle 2 reichen von der einen Stirnseite 3 bis zur anderen Stirnseite 4. Der Kanalblock ist symmetrisch zu seinen Mittelachsen ausgebildet.The heat exchanger according to FIG. 1 essentially consists of a channel block 1, which has a substantially cuboid shape and is injection molded from plastic in one part. In one plane, it has annular channels 2 of equal size in cross section. The channels 2 extend from one end face 3 to the other end face 4. The channel block is formed symmetrically to its central axes.

Die Innenwand 5 jedes Kanals ist mit 3 Stegen 6 versehen, die um 120 Grad gegeneinander versetzt sind und sich von der einen Stirnseite bis zu anderen in der Längserstreckung des Kanalblocks ausrichten. Die Kanäle haben Kreisquerschnitt.The inner wall 5 of each channel is provided with 3 webs 6, which are offset from one another by 120 degrees and align from one end face to the other in the longitudinal extent of the channel block. The channels have a circular cross section.

Die auf beiden Stirnseite 3 und 4 des Kanalblocks 1 aufgesetzten Deckelteile 7 und 8 sind identisch ausgebildet und stellen Kunststoffspritzteile dar. Sie weisen zwei nebeneinanderliegende Ab- und Zulaufkanäle 9 und 10 auf, die mit Abstufungen 11 versehen sind. Diese Abstufungen sind so gestaltet, daß sich der Querschnitt des Kanals 10 nach jedem Abzweig zu einem der Kanäle 2 verkleinert. Der Einläß in den Kanal 10 ist durch einen Stutzen 12 gebildet, durch den das aufheizende Fluid einströmt. Der benachbarte Kanal 9 dient zur Abführung des aufgeheizten Fluids.The cover parts 7 and 8 placed on both end faces 3 and 4 of the channel block 1 are of identical design and represent injection-molded plastic parts. These gradations are designed so that the cross section of the channel 10 decreases after each branch to one of the channels 2. The inlet into the channel 10 is formed by a nozzle 12 through which the heating fluid flows. The adjacent channel 9 serves to discharge the heated fluid.

Aus der Schnittdarstellung des mittleren Kanals 2 in Figur eins ist zu ersehen, daß von dem Zulaufkanal 10 ein Stichkanal 13 abzweigt, der stromauf der folgenden Abstufung 11 liegt. In diesen Stichkanal ist, vergleiche vergrößerte Detaildarstellung gemäß Figur drei, ein Anschlußstutzen 14 eines zu einer Wendel aufgerollten Kupferrohres 15 eingeschoben. Das andere Ende des Wendelrohres trägt gleichermaßen einen Anschlußstutzen 14, der in einen entsprechenden Stichkanal 13 im anderen Deckel einmündet. Beide Deckel 7 und 8 sind identisch ausgebildet. Das Ende des Stichkanals 13 im Deckel 8, vergleiche Darstellung gemäß Figur drei, ist mit drei Stufen 16 bis 18 versehen, die sich im Durchmesser des zylindrischen Stichkanals 13 erweitern. Die Stufe 16 dient als Anschlag für den Stutzen 14. Zwischen den Stufen 17 und 18 sind 2 O-Ringe 19 unter Zwischenschaltung eines im Außendurchmesser kleineren und im Innendurchmesser größeren Distanzringes 20 eingeschoben. Somit herrscht Spiel am Außen- und Innendurchmesser des Distanzringes einerseits zur Innenwandung des Stichkanals 13 zwischen den Stufen 17 und 18 und andererseits an der Außenwandung des Anschlußstutzens 14. Die Kombination der drei Ringe 19 und 20 ist durch einen Sperring 21 gesichert, der an die Stufe 18 anschlägt. Der Sperring ist in seinem Innendurchmesser 22 konisch gehalten, damit der Stutzen 14 leicht eingeführt werden kann. Zwischen den Stufen 17 und 18 führt eine Bohrung 29 nach außen.From the sectional view of the middle channel 2 in FIG. 1 it can be seen that a branch channel 13 branches off from the inlet channel 10 and lies upstream of the following gradation 11. A connection piece 14 of a copper tube 15 rolled up into a coil is inserted into this branch channel, see enlarged detail representation according to FIG. Three. The other end of the helical tube likewise carries a connecting piece 14 which opens into a corresponding branch channel 13 in the other cover. Both covers 7 and 8 are identical. The end of the puncture channel 13 in the cover 8, see illustration according to FIG. Three, is provided with three steps 16 to 18, which expand in the diameter of the cylindrical puncture channel 13. The step 16 serves as a stop for the connecting piece 14. Between the steps 17 and 18, two O-rings 19 are inserted with the interposition of a spacer ring 20 which is smaller in outer diameter and larger in inner diameter. Thus there is play on the outer and inner diameter of the spacer ring on the one hand to the inner wall of the branch channel 13 between the steps 17 and 18 and on the other hand on the outer wall of the connecting piece 14. The combination of the three rings 19 and 20 is through secured a locking ring 21 which strikes the stage 18. The locking ring is tapered in its inner diameter 22 so that the connector 14 can be easily inserted. Between stages 17 and 18, a bore 29 leads to the outside.

Der Kanal 9 ist somit mit den drei in den Kanälen 2 angeordneten Rohren 15 verbunden, die Rohre sind hydraulisch parallel geschaltet. Der Kanal 10 ist über jeweils senkrecht verlaufende Abknickkanäle 23 mit den Innenräumen der Rohre 2 verbunden. Diese Innenräume, die praktisch begrenzt werden von der Innenwand der Kanäle 2 und den Außenmänteln der Rohre 15, liegen ebenfalls alle parallel. Der Kanal 9 mündet in einen Anschlußstutzen 24, an dem das aufgeheizte Fluid entnehmbar ist.The channel 9 is thus connected to the three tubes 15 arranged in the channels 2, the tubes being hydraulically connected in parallel. The channel 10 is connected to the interior spaces of the tubes 2 by way of vertically extending bend channels 23. These interiors, which are practically delimited by the inner wall of the channels 2 and the outer jackets of the tubes 15, are also all parallel. The channel 9 opens into a connecting piece 24, from which the heated fluid can be removed.

Durch die den Stirnseiten 3 und 4 des Kanalblocks zugewandten Seiten der Deckel ragen somit die drei Stichkanäle 13 sowie die drei Abknickkanäle 23, die jeweils zu den Zulaufkanälen 9 und 10 gehören. Weiterhin sind an diesen Seiten der Deckel ringförmige Zapfen 24 vorgesehen, die als Führungszapfen für Distanzrohre 25 dienen. Die Distanzrohre durchgreifen die Rohre 15, so daß für das eine Fluid nur ein Zwischenraum zwischen dem Außenmantel des Distanzrohres und dem Innenmantel des Kanals 2 übrigbleibt. Der Außenmantel 26 der Distanzrohre 25 ist, vergleiche Figur zwei, mit drei regelmäßig verteilten Stegerhebungen 27 versehen, die sich gegen die Innenwandung der Wendel des Rohres 15 anlehnt.The three branch channels 13 and the three bend channels 23, which each belong to the inlet channels 9 and 10, thus project through the sides of the cover facing the end faces 3 and 4 of the channel block. Furthermore, ring-shaped pins 24 are provided on these sides, which serve as guide pins for spacer tubes 25. The spacer tubes pass through the tubes 15, so that for the one fluid only one space remains between the outer jacket of the spacer tube and the inner jacket of the channel 2. The outer jacket 26 of the spacer tubes 25, see FIG. Two, is provided with three regularly distributed web elevations 27, which bears against the inner wall of the coil of the tube 15.

Die Montage des gesamten Wärmetauschers geschieht wie folgt : Der untere Deckel 8 wird in eine Montagevorrichtung eingespannt, so daß die dem Kanalblock 1 zugewandte Seite nach oben ragt. Anschließend werden drei Distanzrohre 25 auf die Führungszapfen 24 im Bereich dieser Seite des Deckels 8 aufgestellt. Sodann werden drei der aus Kupfer hergestellten Wendelrohre 15 genommen und in die Stichkanäle 13 eingesteckt, bis das Rohrende gegen die Stufe 16 anschlägt. Sodann wird der Kanalblock 1 aufgestellt, der gegebenenfalls auch über Führungsstücke oder Zapfen an der aufwärts gerichteten Fläche des Bodens abgeführt ist. Schließlich wird der obere Deckel 7 aufgesetzt. Anschließend werden beide Deckel mit dem Kanalblock 1 über Schrauben 28 verschraubt.The entire heat exchanger is assembled as follows: the lower cover 8 is clamped in an assembly device so that the side facing the duct block 1 projects upwards. Then three spacer tubes 25 are placed on the guide pins 24 in the area of this side of the cover 8. Then three of the helical tubes 15 made of copper are taken and inserted into the branch channels 13 until the tube end abuts the step 16. Then the channel block 1 is set up, which is possibly also removed via guide pieces or pins on the upward-facing surface of the floor. Finally, the upper cover 7 is put on. Then both covers are screwed to the channel block 1 using screws 28.
