Description

Bei den bekannten, dem Wärmeaustausch von gasförmigen oder flüssigen Mitteln dienenden Vorrichtungen, wie z. B. Röhrenrekuperatoren, wird ein Mittel auf dem einen Wege durch Röhren geleitet, die auf dem anderen Wege von einem Mittel im Gegenstrom in mehr oder weniger ungeordneten Strömen umspült werden. Die wärmeaustauschende Wand ist die meist metalleneIn the known, the heat exchange of gaseous or liquid agents used Devices such. B. tube recuperators, a means is passed on the one way through tubes that on the other ways are washed around by a means in countercurrent in more or less disordered currents. The heat exchanging Wall is the mostly metal one

ίο Wand der Röhren. Die bei den bekannten Vorrichtungen verwendeten wärmeaustauschenden Wände gewährleisten jedoch keinesfalls einen weitgehenden Wärmeaustausch. Es ist dies wohl darauf zurückzuführen, daß starke Wärmeströmungen in Richtung der ■strömenden Gase oder Flüssigkeiten stattfinden. ίο wall of tubes. The heat exchangers used in the known devices However, walls in no way guarantee extensive heat exchange. This is probably due to the fact that strong heat flows in the direction of the ■ flowing gases or liquids.

Es gibt auch Wärmeaustauscher aus schlecht leitendem Stoff, z. B. Schamotte; bei diesen ist zwar der Wärmefluß in der Richtung der strömenden Mittel stark herabgesetzt, aber gleichzeitig wird auch der Wärmeaustausch von einem Mittel zum andern durch diesen schlecht leitenden Stoff sehr ungünstig beeinflußt.There are also heat exchangers made of poorly conductive material, e.g. B. chamotte; at Although the heat flow in the direction of the flowing means is greatly reduced, but at the same time there is also an exchange of heat from one medium to another affects this poorly conductive substance very unfavorably.

Es wurde nun gefunden, daß man diesem Übelstand abhelfen und einen vollkommenen Wärmeaustausch erzielen kann, wenn man Rekuperatoren verwendet, deren wärmeaustauschende Wände so zusammengesetzt sind, daß ihre Wärmeleitfähigkeit in der Strömungsrichtung der Mittel möglichst klein und in der Richtung quer hierzu möglichst groß ist. Man erreicht dies beispielsweise durch Unterteilung der Wände und Zwischenschaltung nichtleitender Schichten.It has now been found that this evil can be remedied and one perfect Heat exchange can be achieved if one uses recuperators, their heat exchanging Walls are composed so that their thermal conductivity is in the direction of flow the means is as small as possible and as large as possible in the direction transverse to this. This can be achieved, for example, by Subdivision of the walls and interposition of non-conductive layers.

Die Skizze zeigt eine Ausführungsform, welche diesen Bedingungen gerecht wird. Die Vorrichtung besteht aus Platten a1; a2, a3 usw. aus gut leitendem Stoff, welche Bohrungen C1, C2, €3 usw. besitzen. Diese Platten sind übeneinandergielegt unter Zwischenschaltung wärmeisolierender und abdichtender Platten b1; -b2, b3 usw. Die Gase oder Flüssigkeiten werden durch Bohrungen oder Kanäle durch den so gebildeten Körper hindurchgeführt.The sketch shows an embodiment which meets these conditions. The device consists of plates a 1; a 2 , a 3 , etc. made of highly conductive material, which have holes C 1 , C 2 , € 3 , etc. These plates are placed on top of one another with the interposition of heat-insulating and sealing plates b 1; -b 2 , b 3 etc. The gases or liquids are passed through bores or channels through the body thus formed.
