Sämtliche Rohrbündel verlaufen zwischen zwei allen Rohrbündeln gemeinsamen Rohrböden, und die Kopfkammern über jedem der Rohrböden sind so in Teilkammern unterteilt, daß eine Eintrittsverteilerkammer für das Primärmedium zur Verteilung auf die Rohre des ersten Rohrbündels, sodann eine Reihe von über dem einen bzw. dem anderen Rohrboden angeordneten Verbindungskammern zur Verbindung der Auslaßenden jeweils eines Rohrbündels mit den Einlaßenden eines benachbarten Rohrbündels und schließlich eine Auslaßsammelkammer über den Auslaßenden des letzten Rohrbündels in der strömungstechnischen Reihenschaltung gebildet sind. Zwischen den einzelnen Rohrbündeln sind im Gehäuse Trennwände angeordnet, die jeweils nahe dem einen bzw. dem anderen Rohrboden Übertrittsöffnungen aufweisen, so daß das Sekundärmedium in eine Rohrbündelkammer eintritt und dann durch die Übertrittsöffnungen von Rohrbündelkammer zu Rohrbündelkammer und schließlich aus der letzten Rohrbündelkammer in einen Auslaß gelangt.Such multiple tube bundle heat exchangers are already known. For example, CH 586 882 describes a countercurrent tube bundle heat exchanger in the form of a series tube bundle heat exchanger, in which in a common Housing several tube bundles are arranged, the fluidic are connected in series and successively from Flow through the primary medium. All tube bundles run between two tube sheets common to all tube bundles, and the head chambers above each of the tube sheets are thus in partial chambers divided that an entry distribution chamber for the Primary medium for distribution to the tubes of the first tube bundle, then a series of one over the other Tube plate arranged connecting chambers for connecting the Outlet ends of a tube bundle with the inlet ends of an adjacent tube bundle and finally an outlet plenum over the outlet ends of the last tube bundle in the fluidic series connection are formed. Between The individual tube bundles are partitions in the housing arranged, each near the one or the other tube sheet Have transfer openings so that the secondary medium enters a tube bundle chamber and then through the Transfer openings from tube bundle chamber to tube bundle chamber and finally from the last tube bundle chamber into one Outlet.

    • Der in Fig. 1 dargestellte Wärmetauscher weist ein Gehäuse und eine Mehrzahl darin angeordneter Rohrbündel auf.The heat exchanger shown in Fig. 1 has a housing and a plurality of tube bundles arranged therein.

    Das Gehäuse besteht aus einem Mantel 1, an welchem ein Einlaßstutzen 11 und ein Auslaßstutzen 12 zur Einleitung bzw. Ausleitung eines Sekundärmediums in die bzw. aus den Mantelräumen angeordnet sind, und an dessen beiderseitigen axialen Enden Flansche 13 gebildet sind, weiter aus zwei Kopfstücken 2 und 3, die sich an die beiderseitigen Enden des Mantels 1 anschließend angeordnet sind und jeweils einen Einlaß- bzw. Auslaßstutzen 21 bzw. 31 für ein durch die Rohrbündel hindurchzuleitendes Primärmedium aufweisen, und denen jeweils eine Deckplatte 22 bzw. 32 zugeordnet ist, die über Schrauben bzw. Gewindestangen 23 bzw. 33 mit den Flanschen 13 des Mantels 1 zusammenspannbar sind.The housing consists of a jacket 1, on which an inlet connector 11 and an outlet nozzle 12 for introduction or Discharge of a secondary medium into or from the jacket spaces are arranged, and on its mutual axial Ends flanges 13 are formed, further from two head pieces 2 and 3, which are on the two ends of the jacket 1 are then arranged and each have an inlet or Outlet port 21 or 31 for a to be passed through the tube bundle Have primary medium, and each a cover plate 22 or 32 is assigned, which via screws or threaded rods 23 or 33 with the flanges 13 of the jacket 1 can be put together.

    In dem Gehäuse ist eine Mehrzahl von Rohrbündeln 5 eingebaut, und zwar beim dargestellten Ausführungsbeispiel drei Rohrbündel, die mit 5A, 5B und 5C bezeichnet sind. Jedes Rohrbündel besteht aus einer Anzahl paralleler und mit gegenseitigen Abständen angeordneter Wärmeaustauscherrohre 51 sowie jeweils einem damit verbundenen Rohrboden 52 an den beiden axialen Enden des Rohrbündels.A plurality of tube bundles 5 is installed in the housing, namely in the illustrated embodiment three tube bundles, designated 5A, 5B and 5C. Every tube bundle consists of a number of parallel and with mutual distances arranged heat exchanger tubes 51 and each an associated tube sheet 52 on the two axial Ends of the tube bundle.

    Jedes aus den Wärmeaustauscherrohren 51 und den beiden zugehörigen Rohrböden 52 bestehende Rohrbündel bildet eine Baugruppe in Form einer integralen Einheit und ist als solche in das Gehäuse eingebaut. Die zur Abdichtung zwischen dem Mantel 1, den Kopfstücken 2 und 3 und den Rohrböden 52 verwendeten Dichtungen sind in der Zeichnung schematisch dargestellt und leicht als stilisierte O-Ringdichtungen erkennbar, wobei selbstverständlich die konkrete Art der verwendeten Dichtungen nach Bedarf beliebig wählbar ist.Each of the heat exchanger tubes 51 and the two associated tube sheets 52 existing tube bundle forms a Assembly in the form of an integral unit and is as such built into the housing. The seal between the Sheath 1, the head pieces 2 and 3 and the tube sheets 52 used Seals are shown schematically in the drawing and easily recognizable as stylized O-ring seals, where of course the specific type of used Seals can be selected as required.

    Der Gehäuseraum innerhalb des Mantels 1 ist durch eingebaute Trennwände 14 in eine der Anzahl der Rohrbündel 5 entsprechende Anzahl von Mantelräumen 10A, 10B und 10C unterteilen. Diese Trennwände 14 sind oben und unten mit Durchtrittsöffnungen 15 versehen, über welche die einzelnen Mantelräume miteinander verbunden sind.The housing space inside the jacket 1 is built-in Partitions 14 in a number 5 corresponding to the tube bundle Divide the number of shell spaces 10A, 10B and 10C. These partitions 14 are at the top and bottom with through openings 15 provided, through which the individual jacket rooms are interconnected.

    Wie man sieht, sind die Kopfkammern, die in den Kopfstücken 2 und 3 gebildet sind, nicht unterteilt, sondern erstrecken sich über alle drei Rohrbündel, so daß eine parallele Durchströmung der drei Rohrbündel 5A, 5B und 5C stattfindet. Die drei Rohrbündel sind also strömungstechnisch parallel geschaltet.As you can see, the head chambers that are in the head pieces 2 and 3 are formed, not divided, but extend over all three tube bundles, so that a parallel flow of the three tube bundles 5A, 5B and 5C takes place. The three tube bundles are therefore connected in parallel in terms of flow.

    Fig. 2 zeigt eine Anordnung, die wiederum aus einem Gehäuse mit drei darin eingebauten Rohrbündeln 5A, 5B und 5C besteht. Der Aufbau des Gehäuses mit Mantel 1, Kopfstücken 2 und 3 sowie den Anschlußstutzen 11, 12, 21 und 31 für die am Wärmeaustausch beteiligten Medien, und die Unterteilung des Mantelinnenraums durch Trennwände 14 in drei Mantelräume 10A, 10B und 10C entspricht der Anordnung nach Fig. 1.Fig. 2 shows an arrangement, which in turn consists of a housing with three tube bundles 5A, 5B and 5C installed therein. The structure of the housing with jacket 1, head pieces 2 and 3 as well the connecting piece 11, 12, 21 and 31 for the heat exchange involved media, and the subdivision of the coat interior through partitions 14 in three jacket spaces 10A, 10B and 10C corresponds to the arrangement according to FIG. 1.

    Die drei Rohrbündel sind in gleicher Weise wie diejenigen in Fig. 1 aufgebaut und bestehen wiederum jeweils aus Wärmeaustauscherrohren 51 und jeweils einem Rohrboden 52 an den beiden gegenüberliegenden axialen Enden, wobei wiederum jedes Rohrbündel eine aus diesen Teilen bestehende integrale Einheit bzw. Baugruppe darstellt. The three tube bundles are the same as those in Fig. 1 constructed and in turn each consist of heat exchanger tubes 51 and a tube sheet 52 on each of the two opposite axial ends, each again Pipe bundle is an integral unit consisting of these parts or assembly.

    Jedoch sind bei der Anordnung nach Fig. 2 gegenüber derjenigen nach Fig. 1 die Kopfstücke 2 und 3 und die Trennwände 14 im Mantel 1 derart modifiziert, daß die drei Rohrbündel bei der Anordnung in Fig. 2 strömungstechnisch in Reihe geschaltet sind und das durch den Stutzen 11 eintretende und den Stutzen 12 austretende Sekundärmedium in allen drei Rohrbündeln im Gegenstrom zum Primärmedium geführt wird, das durch den Stutzen 21 eintritt und den Stutzen 31 austritt und die Wärmetauscherrohre 51 der drei Rohrbündel nacheinander durchströmt. Dazu sind die Kopfstücke 2 und 3 so modifiziert, daß über dem Einlaßende des, in Strömungsrichtung des Primärmediums gesehen, ersten Rohrbündels 5C eine Einlaßkammer 24 gebildet ist, weiter im Kopfstück 3 bzw. im Kopfstück 2 jeweils eine Übertrittskammer 35 bzw. 25 zur Überleitung des Primärmediums zwischen den benachbarten Enden zweier strömungstechnisch aufeinanderfolgender Rohrbündel (von 5C auf 5B durch die Übertrittskammer 35 bzw. von 5B auf 5A durch die Übertrittskammer 25), und über dem Austrittsende des letzten Rohrbündels, in Strömungsrichtung des Primärmediums gesehen, also 5A, eine Austrittskammer 36 gebildet ist. In den Kopfstücken 2 und 3 sind also Trennwände 27 bzw. 37 zur entsprechenden Unterteilung des Kopfstückraums in die entsprechenden Kammern gebildet.However, in the arrangement of FIG. 2 compared to that 1, the head pieces 2 and 3 and the partitions 14th modified in the jacket 1 so that the three tube bundles at the arrangement in Fig. 2 fluidically connected in series are and the entering through the nozzle 11 and the Nozzle 12 escaping secondary medium in all three tube bundles is carried in counterflow to the primary medium, which by the nozzle 21 enters and the nozzle 31 exits and the Flows through heat exchanger tubes 51 of the three tube bundles in succession. For this purpose, the head pieces 2 and 3 are modified so that above the inlet end of the, in the flow direction of the primary medium seen, first tube bundle 5C an inlet chamber 24 is formed is further in the head piece 3 or in the head piece 2 in each case a transfer chamber 35 or 25 for transferring the primary medium fluidically between the adjacent ends of two successive tube bundles (from 5C to 5B through the transfer chamber 35 or from 5B to 5A through the transfer chamber 25), and above the exit end of the last Tube bundle, seen in the flow direction of the primary medium, 5A, an outlet chamber 36 is formed. In the headers 2 and 3 are thus partitions 27 and 37 respectively Subdivision of the header space into the corresponding Chambers formed.

    In den Trennwänden 14 ist jeweils nur eine Übertrittsöffnung 15 vorgesehen, die jeweils nahe der jeweiligen Rohrböden gelegen ist, so daß das Sekundärmedium jeweils im Gegenstrom zu dem das Rohrbündel durchströmenden Medium durch im wesentlichen die gesamte axiale Länge der betreffenden Mantelkammer strömen muß, bis es durch die jeweilige Übertrittsöffnung 15 in die benachbarte Mantelkammer übertreten kann.There is only one transition opening in each of the partitions 14 15 provided, each close to the respective tube sheets is located so that the secondary medium in each case in countercurrent to the medium flowing through the tube bundle by essentially the total axial length of the jacket chamber in question must flow until it passes through the respective transition opening 15 can pass into the adjacent jacket chamber.

    Zum Aufbau von Anordnungen nach den Fig. 1 und 2 können standardmäßige Trennwände 14 verwendet werden, die, wie in Fig. 1 dargestellt, an beiden axialen Enden Übertrittsöffnungen haben können, von denen jeweils eine verschlossen wird, um eine Anordnung nach Fig. 2 herzustellen. To build arrangements according to FIGS. 1 and 2, standard Partitions 14 are used which, as in FIG. 1 shown, transition openings at both axial ends may have, one of which is locked in order to produce an arrangement according to FIG. 2.

    Ebenso können unterschiedliche Kopfstücke mit und ohne Trennwände 27 bzw. 37 bereitgehalten werden, so daß aus solchen Elementen je nach Bedarf baukastenmäßig Anordnungen nach den Fig. 1 und 2 hergestellt werden können.Likewise, different head pieces with and without partitions 27 and 37 are kept ready, so that from such Elements according to the modular arrangement according to the 1 and 2 can be produced.

    Die Fig. 3 und 4 zeigen Anordnungen analog denjenigen nach Fig. 1 bzw. Fig. 2, nämlich einen Mehrfachrohrbündel-Wärmeaustauscher mit strömungstechnisch parallel geschalteten Rohrbündeln (Fig. 3) bzw. strömungstechnisch in Reihe geschalteten Rohrbündeln (Fig. 4). Gleiche bzw. entsprechende Teile sind wiederum mit den gleichen Bezugszeichen versehen wie in den Fig. 1 und 2.3 and 4 show arrangements analogous to those after Fig. 1 and Fig. 2, namely a multiple tube bundle heat exchanger with parallel flow technology Pipe bundles (Fig. 3) or connected in series in terms of flow technology Pipe bundles (Fig. 4). Same or corresponding Parts are again provided with the same reference numbers as in FIGS. 1 and 2.

    Die (jeweils wiederum beispielsweise drei) Rohrbündel 5A, 5B und 5C entsprechen denjenigen nach den Fig. 1 und 2.The tube bundles 5A, 5B (each again, for example, three) and 5C correspond to those of FIGS. 1 and 2.

    Auch die Kopfstücke 2 und 3 entsprechen denjenigen nach den Fig. 1 und 2.The headers 2 and 3 correspond to those after 1 and 2.

    Gleiches gilt für den Mantel 1 mit den Anschlußstützen 11 und 12.The same applies to the jacket 1 with the connection supports 11 and 12th

    Die Anordnungen nach den Fig. 3 und 4 unterscheiden sich jedoch durch eine Abwandlung bzw. Weiterbildung des Gehäuseaufbaus von den Anordnungen nach den Fig. 1 und 2. Denn bei den Anordnungen nach den Fig. 3 und 4 sind die Trennwände 14 ohne Übertrittsöffnungen ausgebildet, also vollständig geschlossen. Stattdessen sind bei den Anordnungen nach den Fig. 3 und 4 die Kopfstücke 2 und 3 jeweils ergänzt durch einen zwischen dem jeweiligen Kopfstück und dem Flansch 13 des Mantel 1 angeordnetes Zwischenstück 4 das Verlängerungen der Trennwände 14 bildet bzw. dort, wo Übertritte zwischen benachbarten Mantelräumen vorgesehen sind, eine Übertrittsöffnung 41 aufweisen.The arrangements according to FIGS. 3 and 4 differ, however through a modification or further development of the housing structure of the arrangements according to FIGS. 1 and 2. Because in the Arrangements according to FIGS. 3 and 4, the partitions 14 without Transition openings are formed, that is to say completely closed. Instead, in the arrangements according to FIGS. 3 and 4 the head pieces 2 and 3 each supplemented by a between the respective head piece and the flange 13 of the jacket 1 arranged Intermediate piece 4 the extensions of the partitions 14 forms or wherever crossings between adjacent jacket spaces are provided, have a transition opening 41.

    Dadurch kann der Mantelteil 1 des Gehäuses samt der Trennwände 14 als Standardteil ausgebildet sein, während unterschiedliche Zwischenstücke 4 als baukastenmäßig zu verwendende Teile zur Herstellung von Übertrittsöffnungen zwischen den Mantelräumen nach Bedarf bereitgehalten werden können.This allows the casing part 1 of the housing together with the partitions 14 be designed as a standard part, while different Intermediate pieces 4 to be used as a modular system Parts for making transfer openings between the Shell rooms can be kept available as needed.

    Bei Anordnungen nach den Fig. 3 und 4 können bei ausreichend großer axialer Länge der Zwischenstücke 4 die Anschlußstutzen für den Mantelraum (bei den dargestellten Ausführungsformen mit 11 bzw. 12 bezeichnet und am Mantel 1 angeordnet) auch an den Zwischenstücken 4 angeordnet sein. Dabei ist es möglich, einen oder beide Anschlußstutzen nicht nur seitlich an dem jeweiligen Zwischenstück 4 anzubringen, sondern ihn auch axial anzuordnen und durch das jeweilige Kopfstück 2 bzw. 3 hindurchzuführen.With arrangements according to FIGS. 3 and 4 can be sufficient great axial length of the intermediate pieces 4 the connecting piece for the jacket space (in the illustrated embodiments designated 11 and 12 and arranged on the jacket 1) also the intermediate pieces 4 may be arranged. It is possible one or both connecting pieces not only on the side of the to attach the respective intermediate piece 4, but also it to be arranged axially and through the respective head piece 2 or 3 lead through.

    Die obigen Ausführungsformen wurden aufgrund der in den Zeichnungen angegebenen Pfeile als Gegenstrom-Wärmeaustauscher beschrieben. Es versteht sich, daß diese in gleicher Weise auch als Gleichstrom-Wärmeaustauscher betrieben werden können, wozu nur die Strömungsrichtung eines der beiden Medien umgekehrt zu werden braucht.The above embodiments were based on the in the Drawings indicated arrows as a countercurrent heat exchanger described. It is understood that these are the same Way also be operated as a direct current heat exchanger can, for which purpose only the flow direction of one of the two media needs to be reversed.

    Das erfindungsgemäße Konzept ermöglicht den Aufbau beliebiger Wärmetauscher unter Verwendung von standardmäßigen Komponenten. Insbesondere können die Rohrbündel als Standardkomponenten ausgebildet werden, aus denen unabhängig von dem vorgesehenen Betrieb als Gleichstrom- oder Gegenstrom-Wärmeaustauscher beliebige Mehrfachrohrbündel-Wärmeaustauscheranordnungen unterschiedlicher Größe aufgebaut werden können. Für Wärmeaustauscher unterschiedlicher Größe können unterschiedliche Gehäusebauteile, nämlich Mäntel und Kopfstücke, bereitgehalten werden, die zur Aufnahme jeweils einer bestimmten Anzahl von Rohrbündeln ausgebildet sind, oder es können variable Blockanordnungen von solchen Gehäusebauteilen vorgesehen sein. Durch Verwendung entsprechender Kopfstücke, nämlich eines solchen für Parallelbetrieb oder eines solchen für Reihenschaltung der Rohrbündel, können aus relativ wenig Grundkomponenten nach Bedarf Wärmetauscheranordnungen baukastenmäßig und somit sehr wirtschaftlich aufgebaut werden.The concept according to the invention enables the construction of any Heat exchangers using standard components. In particular, the tube bundles can be used as standard components be trained, from which regardless of the intended Operation as a cocurrent or countercurrent heat exchanger any multiple tube bundle heat exchanger arrangements different sizes can be built. For heat exchangers different size can be different Housing components, namely coats and head pieces, kept ready be used to record a certain number of tube bundles are formed, or it can be variable Block arrangements of such housing components are provided his. By using appropriate headers, namely one for parallel operation or one for Series connection of the tube bundle can be made of relatively little Basic components as required, modular heat exchanger arrangements and thus be built very economically.
