Description

Die Erfindung betrifft durchlässige Strukturen, hergestellt aus geschnittenen Karten aus keramischem Material, insbesondere für Wärmetauscher.The invention relates to permeable structures made from cut Cards made of ceramic material, in particular for heat exchangers.

Durchlässige Strukturen der genannten Art sind aus der DE 40 22 654 A1 bekannt. Diese Strukturen weisen parallel zueinander verlaufende Lochreihen auf, zwischen denen Kanäle angeordnet sind, die in wechselnder Folge mit Stegen als Kühlrippen versehen sind. Der Wärmeaustausch erfolgt über diese Rippen, was lange Wege zur Folge hat. Hier will die Erfindung Abhilfe schaffen.Permeable structures of the type mentioned are known from DE 40 22 654 A1 known. These structures have rows of holes running parallel to each other on, between which channels are arranged, which alternate with Webs are provided as cooling fins. The heat exchange takes place via this Ribs, which results in long journeys. The invention seeks to remedy this.

Die Erfindung löst die Aufgabe durch eine durchlässige Struktur, die dadurch gekennzeichnet ist, daß die Struktur Kanalsysteme aufweist, die aus parallel verlaufenden Kanälen und dazu quer auf gleicher Ebene ebenfalls parallel verlaufenden Kanälen bestehen, wobei die parallel verlaufenden Kanäle im Bereich der quer verlaufenden Kanäle einen Höhenversatz aufweisen und untereinander durch Mischkammern verbunden sind und die quer verlaufenden Kanäle mittels Umlenkkanäle umgelenkt und höhenversetzt werden. Anstelle der Umlenkkanäle können auch Mischkammern bei den Kanälen eingesetzt werden. Die Kanäle können in Anschlußkanälen beginnen bzw. enden.The invention solves the problem with a permeable structure is characterized in that the structure has channel systems that consist of parallel running channels and also parallel across the same level extending channels exist, the parallel channels in the region of the transverse channels have a height offset and with each other through mixing chambers are connected and the transverse channels are deflected by means of deflection channels and be offset in height. Instead of the deflection channels, too Mixing chambers are used in the channels. The channels can be in Connection channels begin or end.

Mindestens eines der beiden Kanalsysteme kann in zwei getrennte Kanalsysteme aufgeteilt sein.At least one of the two channel systems can be divided into two separate channel systems be divided.

Die Vorteile der Erfindung sind im wesentlichen darin zu sehen, daß der Wärmeaustausch vorwiegend über schmale, dünne Hindernisse (kurze Wege) erfolgt. Darüber hinaus wird durch den Höhenversatz der Kanäle in den Umlenkkanälen bzw. Mischkammern und Sammelkanälen das Strömungsprofil neu gestaltet (verwirbelt), wodurch der Wärmeübergang zusätzlich verbessert wird.The advantages of the invention are essentially the fact that the Heat exchange predominantly over narrow, thin obstacles (short distances) he follows. In addition, the height offset of the channels in the Deflection channels or mixing chambers and collecting channels the flow profile redesigned (swirled), which additionally improves the heat transfer becomes.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Es zeigtIn the following, the invention will be explained using only one embodiment illustrative drawings explained in more detail. It shows

Fig. 1 eine durchlässige Struktur als Zwei-Wege-System perspektivisch und teilweise geschnitten, Fig. 1 is a permeable structure as a two-way system in perspective and partly in section,

Fig. 2 ein Kanalsystem nach Fig. 1 perspektivisch in Explosionsdarstellung und Fig. 2 shows a duct system according to FIG. 1 in perspective in an exploded view and

Fig. 3 die Struktur gemäß Fig. 1 als Drei-Wege-System. Fig. 3 shows the structure of FIG. 1 as a three-way system.

Die durchlässige Struktur ist aus strukturierten Karten aus keramischem Material aufgebaut. Die Struktur kann durch Sägen, Fräsen, Drehen, Lasern, Stanzen und Flüssigkeitsstrahlschneiden in der Karte erzeugt werden. Die einzelnen Karten werden in bestimmter Reihenfolge aufeinander gestapelt, laminiert und zu einem Monolithen gebrannt. Dabei entstehen parallel verlaufende Kanäle 1 und dazu quer auf gleicher Ebene ebenfalls parallel verlaufende Kanäle 2. Die Kanäle 1 weisen im Bereich der Kanäle 2 einen Höhenversatz 4 auf. Die Kanäle 1 der verschiedenen Ebenen sind durch Mischkammern 3 untereinander verbunden. Nebeneinander liegende Kanäle 1 sind durch Stege 6 getrennt. Die Kanäle 2 können im Anschlußkanal 5 beginnen und laufen dann quer zu den Kanälen 1 über Umlenkkanäle oder Mischkammern 7 zu einem Anschlußkanal 8, wobei dann entweder Anschlußkanal 5 oder Anschlußkanal 8 als Zulauf oder Ablauf benutzt werden kann. Alternativ beginnen bzw. enden die Kanäle 2 mit einem großen Sammelraum oder wie bei den Kanälen 1 der Fig. 1 und 2 mit einer Vielzahl an Einzelkanälen. Die Umlenkkanäle 7 verbinden den vorderen und den hinteren Teil des Kanals höhenversetzt. Falls anstelle der Umlenkkanäle 7 Mischkammern verwendet werden, findet ebenfalls Durchmischung statt. Durch entsprechende Zwischenschichten kann das Kanalsystem 1 und/oder das Kanalsystem 2 in jeweils 2 getrennte Kanalsysteme aufgeteilt werden (2-, 3- oder 4-Wegesystem). Gemäß Fig. 3 ist das Kanalsystem 2 in zwei separate Kanalsysteme 2a und 2b aufgeteilt. 5a, 5b, 8a, 8b deuten die Anschlußkanäle und 7a, 7b die Umlenkkanäle an.The permeable structure is made up of structured cards made of ceramic material. The structure can be created in the card by sawing, milling, turning, lasering, punching and liquid jet cutting. The individual cards are stacked on top of one another in a specific order, laminated and burned into a monolith. This creates parallel channels 1 and also parallel channels 2 running transversely on the same level. The channels 1 have a height offset 4 in the area of the channels 2 . The channels 1 of the different levels are interconnected by mixing chambers 3 . Channels 1 lying next to one another are separated by webs 6 . The channels 2 can begin in the connecting channel 5 and then run across the channels 1 via deflection channels or mixing chambers 7 to a connecting channel 8 , in which case either connecting channel 5 or connecting channel 8 can be used as an inlet or outlet. Alternatively, the channels 2 begin or end with a large collecting space or, as with the channels 1 in FIGS. 1 and 2, with a large number of individual channels. The deflection channels 7 connect the front and the rear part of the channel offset in height. If 7 mixing chambers are used instead of the deflection channels, mixing also takes place. Corresponding intermediate layers allow the duct system 1 and / or the duct system 2 to be divided into 2 separate duct systems (2-, 3- or 4-way system). Referring to FIG. 3, the channel system 2 into two separate channel systems 2 a and 2 b divided. 5 a, 5 b, 8 a, 8 b indicate the connecting channels and 7 a, 7 b the deflection channels.
