Description

Die Erfindung betrifft einen Gas/Flüssigkeit- oder Gas/Gas-Wärmeaustauscher mit Schichten, die jeweils eine Vielzahl zueinander paralleler einstückiger Wärmeleitlamellen aufweisen, die im Gegenstromverfahren die Wärme von einem Medium zu einem zweiten übertragen.The invention relates to a gas / liquid or gas / gas heat exchanger with layers, each having a plurality of mutually parallel one-piece heat-conducting fins, which transfer the heat from one medium to a second in a countercurrent process.

Es sind Luft/Wasser- und Luft/Luft-Wärmeaustauscher verschiedenster Bauarten bekannt. Diese weisen Platten bzw. Lamellen und/oder Rohre auf, wobei die beiden Ströme von Luft und/oder Wasser durch Leitungen bzw. Kanäle geführt werden und währenddessen eines der beiden Medien seine Wärme an das andere Medium abgibt. Der höchste Temperaturaustauschgrad wird bei Gegenstromwärmeaustauschern erzielt.Air / water and air / air heat exchangers of various types are known. These have plates or lamellae and / or pipes, the two streams of air and / or water being conducted through lines or channels and, in the meantime, one of the two media giving off its heat to the other medium. The highest degree of temperature exchange is achieved with countercurrent heat exchangers.

All diesen Wärmeaustauschern ist gemeinsam, daß ein hoher Temperaturaustauschgrad nur dann erzielbar ist, wenn der Wärmeaustauscher sehr groß gebaut wird. Solche auf geringste Exergieverluste ausgelegte Wärmeaustauscher führen zu Wärmeaustauscherlängen, welche für die meisten Anwendungsfälle aufgrund der Abmessungen und des Gewichts unpraktikabel sind. Ferner können diese Wärmeaustauscher nur mit erheblichem Aufwand gereinigt werden, und schon bei einem geringen Defekt am Wärmeaustauscher kann eine komplette Erneuerung erforderlich werden.All these heat exchangers have in common that a high degree of temperature exchange can only be achieved if the heat exchanger is built very large. Such heat exchangers designed for minimal exergy losses lead to Heat exchanger lengths, which are impractical for most applications due to the dimensions and weight. Furthermore, these heat exchangers can only be cleaned with considerable effort, and even a small defect in the heat exchanger may require a complete renewal.

Aufgabe der Erfindung ist es, einen Wärmeaustauscher zu schaffen, der einen sehr hohen Temperaturaustauschgrad besitzt, einfach zu reparieren ist und ohne größeren Arbeitsaufwand montiert und demontiert werden kann.The object of the invention is to provide a heat exchanger which has a very high degree of temperature exchange, is easy to repair and can be assembled and disassembled without great effort.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Wärmeaustauscher in Wärmeaustauscherschichten aufgeteilt ist, von denen jede einen vollständigen Wärmeaustauscher bildet, der beide Medien führt und eine Gruppe paralleler Wärmeleitlamellen aufweist, die unlösbar fest sind und in derselben Höhe liegen, daß jede Schicht parallel zu den anderen Schichten mit ihren je zwei Ein- und Auslässen an den Haupteintritts- und Austrittsleitungen des gesamten Wärmeaustauschers separat angeschlossen ist, und daß die Schichten mit benachbarten Schichten lösbar verbunden sind.This object is achieved in that the heat exchanger is divided into heat exchanger layers, each of which forms a complete heat exchanger which guides both media and has a group of parallel heat-conducting fins, which are insoluble and are at the same height, that each layer is parallel to the other layers with their two inlets and outlets are separately connected to the main inlet and outlet lines of the entire heat exchanger, and that the layers are detachably connected to adjacent layers.

Ein solcher Wärmeaustauscher ist in einzelne, im Gegenstromprinzip Wärme austauschende und in sich funktionsfähige Schichtmodule unterteilt. Hierdurch kann für jede beliebige Wärmeaustauschaufgabe die erforderliche Wärmeaustauscher länge gewählt, rationell in Modulen gefertigt und vor Ort an der Anwendungsstelle zusammengebaut werden. Antransport und Montage sind extrem einfach und eine Wartung wenig arbeitsaufwendig. Bei einem Defekt braucht nur die betreffende Wärmeaustauscherschicht repariert oder erneuert zu werden.Such a heat exchanger is divided into individual, in the countercurrent principle heat exchanging and functional layer modules. As a result, the required heat exchanger length can be selected for any heat exchange task, efficiently manufactured in modules and assembled on site at the application site. Transport and assembly are extremely simple and maintenance is not labor intensive. In the event of a defect, only the relevant heat exchanger layer needs to be repaired or replaced.

Da der Wärmeaustauscher in viele Einzelschichten aufgeteilt ist, kann die für den Wärmeaustausch oder für den gewünschten Temperaturaustauschgrad erforderliche Austauscherfläche voreinander - also in Gegenstrom - angeordnet werden. Eine Blockbauweise - wie bisher bekannt - ist herstellbar aber nicht praktikabel. Besonders vorteilhaft ist es, wenn die Höhe jeder Lamelle ein Vielfaches des Abstandes zwischen den Lamellen.beträgt. Dies führt dazu, daß die Wärmeübertragung im wesentlichen über die Lamellen und nicht über die die Mediumkanäle trennenden Wände erfolgt. Die Lamellendicke ist in bezug auf das Lamellenmaterial so dimensioniert, daß eine exergieverlustarme Wärmeleitung entsteht.Since the heat exchanger is divided into many individual layers, it can be used for heat exchange or for required temperature exchange degree required exchanger surface in front of each other - that is, in countercurrent - are arranged. A block construction - as previously known - can be manufactured but is not practical. It is particularly advantageous if the height of each slat is a multiple of the distance between the slats. This means that the heat transfer takes place essentially over the fins and not over the walls separating the medium channels. The lamella thickness is dimensioned in relation to the lamella material in such a way that low-energy loss heat conduction occurs.

Zwischen den einzelnen Schichten des Wärmeaustauschers kann jeweils eine Trennfläche befestigt sein, die den Mediumstrom einer Schicht von dem Mediumstrom der benachbarten Schicht trennt. Dies führt dazu, daß eine Querverwirbelung verhindert wird und Druckverluste besonders gering sind. Ferner kann das sich in einer Schicht bildende Kondensat nicht in andere Schichten laufen und dort verstärkt Druckverluste erzeugen.A separating surface can be attached between the individual layers of the heat exchanger, which separates the medium flow of one layer from the medium flow of the adjacent layer. This means that cross turbulence is prevented and pressure losses are particularly low. Furthermore, the condensate that forms in one layer cannot run into other layers and can increasingly generate pressure losses there.

Insbesondere bei Gas/Gas-Wärmeaustauschern ist es von Vorteil, wenn die Lamellen in beide unterschiedlich warmen Medienwege hineinreichen, da dann insbesondere bei einem engen Lamellenstand sichergestellt ist, daß die Wärmeübertragung im wesentlichen nur über die Lamellen geschieht und damit Exergieverluste besonders gering sind. Hierzu wird auch vorgeschlagen, daß der Wärmestrom von einem Medium zum anderen im wesentlichen nur über die Lamellen erfolgt.In the case of gas / gas heat exchangers in particular, it is advantageous if the fins extend into both media paths of different warmth, since it is ensured, in particular when the fins are narrow, that the heat transfer occurs essentially only via the fins and thus exergy losses are particularly low. For this purpose, it is also proposed that the heat flow from one medium to another is essentially only via the fins.

Zwei Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 eine schematische Darstellung eines Gas/Flüssigkeit-Wärmeaustauschers;
  • Fig. 2 eine perspektivische Ansicht eines Gas/Flüssigkeit-Wärmeaustauschers nach Fig. 1, mit drei Schichten;
  • Fig. 3 eine schematische Darstellung eines Gas/Gas-Wärmeaustauschers;
  • Fig. 4 eine perspektivische Darstellung eines Gas/Gas-Wärmeaustauschers nach Fig. 3.
Two embodiments of the invention are shown in the drawings and are described in more detail below. Show it:
  • Fig. 1 is a schematic representation of a gas / liquid speed heat exchanger;
  • FIG. 2 shows a perspective view of a gas / liquid heat exchanger according to FIG. 1, with three layers;
  • 3 shows a schematic illustration of a gas / gas heat exchanger;
  • 4 shows a perspective illustration of a gas / gas heat exchanger according to FIG. 3.

Der in Fig. 1 dargestellte Gas/Flüssigkeit-, insbesondere Luft/Wasser-Wärmeaustauscher wird von rechts nach links von Gas bzw. Luft und im Gegenstrom von Flüssigkeit bzw. Wasser durchströmt. Er ist in fünf Schichten 2 aufgeteilt, die in sich funktionsfähige Module bilden, die jeweils damit einen kompletten Wärmeaustauscher bilden. Jede Schicht 2 ist am Eintritt 3 und Austritt 4 des Gases als auch am Einlaß 5 und Auslaß 6 der Flüssigkeit getrennt angeschlossen, so daß sich der gesamte Gasstrom als auch der gesamte Flüssigkeitsstrom in einzelne Ströme aufteilt, wobei für jede Schicht ein Strom beider Medien vorgesehen ist und hinter dem Wärmeaustauscher diese Ströme wieder jeweils in einen Gesamtstrom zusammengeführt sind. Während die Gasströme 7 die einzelnen Schichten geradlinig durchströmen, fließt die Flüssigkeit in jeder Schicht 2 in einer Rohrschlange 8 hin und her, wobei hierdurch der Flüssigkeitsstrom den Luftstrom kreuzt und ihm entgegenströmt.The gas / liquid, in particular air / water, heat exchanger shown in FIG. 1 is flowed through from right to left by gas or air and in the counterflow of liquid or water. It is divided into five layers 2, which form functional modules that each form a complete heat exchanger. Each layer 2 is connected separately at the inlet 3 and outlet 4 of the gas as well as at the inlet 5 and outlet 6 of the liquid, so that the entire gas flow and the entire liquid flow are divided into individual flows, a flow of both media being provided for each layer is and behind the heat exchanger these flows are again combined into a total flow. While the gas streams 7 flow straight through the individual layers, the liquid flows back and forth in a pipe coil 8 in each layer 2, whereby the liquid stream crosses and flows against the air stream.

In jeder Schicht 2 sind parallel zum Gasstrom zahlreiche Lamellen 9 an den Rohren 8 befestigt, wobei die Lamellen 9 senkrecht zu den Bereichen der Rohre 8 stehen, die durch die Lamellenschar laufen. Die Lamellendicke ist in bezug auf das Lamellenmaterial so dimensioniert, daß eine exergieverlustarme Wärmeleitung entsteht. Zwischen jeder Schicht 2 ist parallel zu den Rohren 8 und zu jeder Schicht eine Trennfläche 10 befestigt, die die Gaswege jeder Schicht voneinander trennt. Die Rohre jeder Schicht sind am Anfang und Ende der Schicht jeweils über ein Ventil 11 an der Einlaß- 5 bzw. Auslaßleitung 6 angeschlossen, so daß die Schichten bei Erstinbetriebnahme entlüftet werden können und nach Verschließen zweier Ventile 11 jede Schicht leicht außer Betrieb genommen, überprüft, ohne Demontage flüssigkeitsseitig gereinigt oder auch demontiert werden kann.In each layer 2, numerous fins 9 are fastened to the tubes 8 parallel to the gas flow, the fins 9 being perpendicular to the regions of the tubes 8 which run through the family of fins. The lamella thickness is dimensioned in relation to the lamella material in such a way that low-energy loss heat conduction occurs. Between everyone Layer 2 is attached parallel to the tubes 8 and to each layer, a separating surface 10 which separates the gas paths of each layer. The tubes of each layer are connected at the beginning and end of the layer via a valve 11 to the inlet 5 and outlet line 6, respectively, so that the layers can be vented when they are put into operation for the first time and after closing two valves 11 each layer is easily taken out of operation, checked , can be cleaned or dismantled on the liquid side without disassembly.

Der in den Figuren 3 und 4 dargestellte Gas/Gas-, insbesondere Luft/Luft-Wärmeaustauscher kann von links nach rechts von Abluft- (Abgas) bzw. Außenluft 12 und von rechts nach links von einem zweiten Gasstrom 13 durchströmt werden. Der Wärmeaustauscher ist in fünf einzelne, in sich funktionsfähige Schichtmodule 2 aufgeteilt, wobei jedes Modul berippte Wärmeleitflächen aufweist, um den im Gegenstrom strömenden Gasmengen Wärme zu entziehen und zu übertragen. Jede Schicht 2 weist mittig eine Trennebene 14 auf, an der Lamellen 9 rechtwinklig und zueinander parallel befestigt sind. Die beiden Gasströme werden durch diese Ebenen 14 voneinander getrennt, so daß bis auf die Außenbereiche, d.h. in Fig. 4 der obere und untere Bereich, die Gasströme jeweils durch zwei benachbarte Schichten 2 strömen.The gas / gas, in particular air / air, heat exchanger shown in FIGS. 3 and 4 can have exhaust gas (exhaust gas) or outside air 12 flowing through them from left to right and a second gas stream 13 flowing from right to left. The heat exchanger is divided into five individual, functional layer modules 2, each module having finned heat-conducting surfaces in order to extract and transfer heat from the gas flows flowing in countercurrent. Each layer 2 has a separating plane 14 in the center, on which the slats 9 are fastened at right angles and parallel to one another. The two gas streams are separated from one another by these levels 14, so that apart from the outer areas, i.e. 4 the upper and lower region, the gas flows each flow through two adjacent layers 2.

Jede Schicht 2 ist getrennt von den anderen Schichten an den Einlaß und Auslaß beider Gasströme angeschlossen, so daß, wie schon im ersten Ausführungsbeispiel, beide Medienströme aufgeteilt werden und jeweils mit Teilströmen jede Schicht durchströmen und danach zu den beiden Auslässen geführt werden, ohne zu einer nächsten Schicht zu gelangen. Die Lamellen 9 reichen somit jeweils in die Wege zweier unterschiedlicher Medien hinein, und die Lamellen 9 stehen so nah beieinander, daß ein Wärmestrom im wesentlichen nur über die Lamellen erfolgt. Die Höhe der Lamellen H beträgt ein Vielfaches des Abstandes A voneinander. Die Lamellendicke ist in bezug auf das Lamellenmaterial so dimensioniert, daß eine exergieverlustarme Wärmeleitung entsteht.Each layer 2 is connected separately from the other layers to the inlet and outlet of both gas streams, so that, as in the first exemplary embodiment, both media streams are divided and flow through each layer with partial streams and are then led to the two outlets without leading to one to get to the next layer. The lamellae 9 thus extend into the paths of two different media, and the lamellae 9 are so close together that a heat flow essentially only via the slats. The height of the slats H is a multiple of the distance A from each other. The lamella thickness is dimensioned in relation to the lamella material in such a way that low-energy loss heat conduction occurs.

Zwischen den einzelnen Modulschichten 2 des Wärmeaustauschers sind parallele Trennflächen 10 angeordnet, die jeweils beidseitig vom selben Mediumstrom umströmt werden.Parallel separating surfaces 10 are arranged between the individual module layers 2 of the heat exchanger, and the same medium flow flows around them on both sides.

Bei beiden Ausführungsbeispielen ist jede Schicht 2 lösbar an der oder den benachbarten Schichten befestigt, so daß sie leicht auswechselbar und montierbar als auch demontierbar sind. Beide Wärmeaustauscher lassen sich nicht nur in der in den Figuren dargestellten waagerechten Lage, sondern auch in anderen Lagen, insbesondere einer senkrechten, verwenden. Der Temperaturaustauschgrad beträgt 75 bis 90%.In both embodiments, each layer 2 is releasably attached to the adjacent layer or layers, so that they can be easily replaced and assembled and removed. Both heat exchangers can be used not only in the horizontal position shown in the figures, but also in other positions, in particular in a vertical position. The degree of temperature exchange is 75 to 90%.
