The module is produced from a stack of punched and laminated green ceramic cards and consists of at least two cards (2). The cards have recesses (4) which form tubular channels (5) when the cards (2) are stacked. Rings (3) are arranged between the cards as part of the tubular channels (5). <IMAGE>

Description

Die Erfindung betrifft einen Wärmetauschermodul aus gebranntem keramischen Material, der durch Brennen eines Stapels gestanzter und laminierter, grüner keramischer Karten hergestellt wird.The invention relates to a heat exchanger module made of fired ceramic material, which is produced by firing a stack of punched and laminated green ceramic cards.

Nach der FR-A 2 152 729 sind Parallelstrom-Wärmetauscher aus gestapelten Metallplatten bekannt, bei denen der Plattenstapel drei Kanalreihen aufweist, die jeweils von Öffnungen in den Platten gebildet werden. Jede Reihe ist kreisförmig orientiert; alle drei Reihen liegen konzentrisch.According to FR-A 2 152 729, parallel flow heat exchangers made of stacked metal plates are known, in which the plate stack has three rows of channels, each of which is formed by openings in the plates. Each row is oriented in a circle; all three rows are concentric.

Zwischen den Platten befinden sich Ringe, die die konzentrisch angeordneten Reihen von Öffnungen voneinander trennen.There are rings between the plates that separate the concentrically arranged rows of openings.

Wärmetauscher der genannten Art sind aus der DE-A 3 136 253 bekannt. Sie werden aus keramischen Folien bzw. Karten hergestellt, in die die Strömungskanäle eingestanzt oder eingeprägt sind und die durch Laminierhilfsmittel miteinander verbunden werden. Der so erhaltene Wärmetauscherblock wird zunächst erhitzt, und die organischen Bestandteile werden bei 200 - 300°C ausgeheizt. Anschließend wird der Block bei 1200 bis 1700°C gebrannt. Nachteilig ist die große Anzahl unterschiedlicher Kartenmuster für den Aufbau des Blocks, das Nacharbeiten des grünen Blocks, sowie des gebrannten Blocks und die begrenzte Reinigungsmöglichkeit der Kanäle. Hier will die Erfindung Abhilfe schaffen.Heat exchangers of the type mentioned are known from DE-A 3 136 253. They are made from ceramic foils or cards into which the flow channels are stamped or stamped and which are connected to one another by means of lamination aids. The heat exchanger block thus obtained is first heated and the organic components are baked out at 200-300 ° C. The block is then fired at 1200 to 1700 ° C. Disadvantages are the large number of different card patterns for the construction of the block, the reworking of the green block, as well as the burned block and the limited possibility of cleaning the channels. The invention seeks to remedy this.

Der Wärmetauscher soll durch ein Minimum an Kartenmustern herstellbar und für partikelbeladene Gasströme sowie für den Wärmetausch zwischen Flüssigkeit-Gas und Flüssigkeit-Flüssigkeit gleichermaßen einsetzbar sein.The heat exchanger should be able to be produced using a minimum of card samples and be used equally for particle-laden gas flows and for the heat exchange between liquid-gas and liquid-liquid.

Die Aufgabe wird durch einen Wärmetauschermodul der genannten Art gelöst, der dadurch gekennzeichnet ist, daß die Karten Ausnehmungen aufweisen, die bei gestapelten Karten durchgehende Kanäle bilden und zwischen den Karten die Kanäle umgebende Ringe angeordnet sind, wobei sich schlitzförmige Kanäle ausbilden, die sich senkrecht zu den durchgehenden Kanälen erstrecken und diese umgeben.The object is achieved by a heat exchanger module of the type mentioned, which is characterized in that the cards have recesses which form continuous channels in the case of stacked cards and rings are arranged between the cards and the rings surrounding the cards, slot-shaped channels being formed which are perpendicular to extend through and surround the continuous channels.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, daß sich der Modul aus einem Kartenmuster aufbauen läßt. Falls erforderlich kann die Abdichtung des gebrannten Moduls durch einen zweiten Brand und Einbringen von Dichtungsmittel wie z.B. Silizium oder einer Glasur über die für das warme Medium bestimmten rohrförmigen Kanäle in das Innere des Moduls verbessert werden. Der Wärmetauschermodul eignet sich besonders gut zum Aufbau von Wärmetauschersystemen. Dabei werden die Modulen zweckmäßig zu Säulen aufeinandergesetzt. Das heiße Medium wird bei dieser Anordnung geradlinig durch den säulenförmigen Aufbau geleitet. Die Dichtung der Modulen untereinander kann wahlweise durch Verkleben mit organischen oder anorganischen Klebem, Mörteln, Gläsern und ähnlichem Erfolgen. Es eignen sich aber auch übliche Dichtelemente wie Faserschnüre, Faserpapiere, 0-Ringe, C-Dichtungen usw. Die Dichtflächen können strukturiert oder geschliffen sein. In ein Wärmetauschergehäuse können beliebig viele Säulen eingebaut werden. Dabei genügt es die einzelnen Säulen gegen ein festes Widerlage mit Federelementen zur Kompensation von Wärmedehnungen zu verspannen. Eine starre Verbindung der Säulen untereinander ist nicht erforderlich. Sie können jedoch über in Führungsnuten des Moduls eingeschobene Leitelemente positioniert werden. Die Leitelemente können so gestaltet werden, daß das kalte Medium beim Übergang von einer zur nächsten Säule stets in das Modulinnere geleitet wird. Durch die Gestaltung des Wärmetauschergehäuses kann ohne Änderung des Säulenkonzepts die Betriebsweise des Wärmetauschers von z.B. Kreuz- in Kreuz Gegenstrom geändert werden.The advantages achieved by the invention can be seen essentially in the fact that the module can be constructed from a card pattern. If necessary, the fired module can be sealed by a second fire and the introduction of sealants such as Silicon or a glaze can be improved in the interior of the module via the tubular channels intended for the warm medium. The heat exchanger module is particularly well suited for the construction of heat exchanger systems. The modules are expediently stacked on top of one another. In this arrangement, the hot medium is guided in a straight line through the columnar structure. The modules can be sealed together by gluing with organic or inorganic adhesives, mortars, glasses and the like. However, conventional sealing elements such as fiber cords, fiber papers, 0-rings, C-seals, etc. are also suitable. The sealing surfaces can be structured or ground. Any number of columns can be installed in a heat exchanger housing. It is sufficient to brace the individual columns against a fixed abutment with spring elements to compensate for thermal expansion. A rigid connection between the columns is not necessary. However, they can be positioned using guide elements inserted in the module's guide grooves. The guide elements can be designed in such a way that the cold medium is always led into the interior of the module during the transition from one column to the next. Due to the design of the heat exchanger housing, the operation of the heat exchanger can be changed from e.g. Cross to cross can be changed countercurrent.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert.The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment.

Der Wärmetauschermodul 1 besteht aus keramischen Karten 2 und keramischen Ringen 3. Die Karten weisen Ausnehmungen 4 auf und die Ringe 3 haben zweckmäßig die gleiche innere Kontur und den gleichen freien Querschnitt wie die Ausnehmungen 4. Karten 2 mit Ausnehmungen 4 und Ringen 3 werden abwechselnd gestapelt, und zwar so, daß Ringe 3 und Ausnehmungen 4 einen geradlinig verlaufenden rohrförmigen Kanal 5 bilden. Quer zur Richtung der rohrförmigen Kanäle 5 und parallel zur Kartenebene bilden sich schlitzförmige Kanäle 6 aus. Die Höhe der Kanäle 6 kann durch Übereinanderschichten mehrerer Ringe 3 beliebig variiert werden. Die Perforation 7 am Kartenrand kann der Aufnahme von Stapelhilfen, Montagehilfen 8, Leitelementen usw. dienen.The heat exchanger module 1 consists of ceramic cards 2 and ceramic rings 3. The cards have recesses 4 and the rings 3 expediently have the same inner contour and the same free cross-section as the recesses 4. Cards 2 with recesses 4 and rings 3 are stacked alternately , in such a way that rings 3 and recesses 4 form a rectilinear tubular channel 5. Slit-shaped channels 6 are formed transverse to the direction of the tubular channels 5 and parallel to the card plane. The height of the channels 6 can be varied as desired by stacking several rings 3 on top of one another. The perforation 7 on the edge of the card can be used to hold stacking aids, assembly aids 8, guide elements, etc.

Bei dem Wäremtauschersystem gemäß Figuren 3 und 4 sind Wärmetauschermodule 1 zu Säulen 9 zusammengestellt, die parallel zueinander in einem Gehäuse 12 angeordnet sind. Die einzelnen Säulen 9 sind zueinander und in Bezug auf das Gehäuse 12 durch Montagehilfen 8, die auch als Leitelemente ausgebildet sein können, lagemäßig fixiert. Zwischen den Wärmetauschermodulen 1 einer Säule 9 sind Abdichtungen 11 angeordnet, um zu verhindem, daß sich die Wärmetauschermedien vermischen. Gegenüber dem Gehäuse 13 sind die Enden einzelner Säulen 9 ebenfalls durch Dichtungen 11 abgedichtet. Um temperaturbedingte Längenausdehnungen der Säulen 9 aufzufangen, sind die Säulen 9 aus Lagerelementen 17,17' angeordnet, die gegenüber den Säulen 9 mittels Dichtungen 11 und gegenüber dem Gehäuse 12 mittels Dichtungen 11', 13 und 14 abgedichtet sind. Während sich das Lagerelement 17' direkt über Dichtungen 11' am Gehäuse 12 abstützt, stützt sich das Lagerelement 17 über Federn 10 am Gehäuse 12 ab. 15 deutet die Strömungsrichtung des kalten Mediums und 16 die Strömungsrichtung des heißen Mediums an.In the heat exchanger system according to FIGS. 3 and 4, heat exchanger modules 1 are assembled into columns 9, which are arranged parallel to one another in a housing 12. The individual columns 9 are fixed in relation to one another and with respect to the housing 12 by mounting aids 8, which can also be designed as guide elements. Seals 11 are arranged between the heat exchanger modules 1 of a column 9 in order to prevent the heat exchanger media from mixing. The ends of individual columns 9 are also sealed off from the housing 13 by seals 11. In order to absorb temperature-related linear expansion of the columns 9, the columns 9 are arranged from bearing elements 17, 17 ', which are sealed off from the columns 9 by means of seals 11 and from the housing 12 by means of seals 11', 13 and 14. While the bearing element 17 'is supported directly on the housing 12 via seals 11', the bearing element 17 is supported Springs 10 on the housing 12. 15 indicates the flow direction of the cold medium and 16 the flow direction of the hot medium.
