Description
Die Neuerung bezieht sich auf einen Wärmetauscher gemäß dem Oberbegriff des Schutzanspruches 1.The Innovation relates to a heat exchanger according to the preamble of the protection claim 1.
Derartige
Wärmetauscher,
die auch als Folienwärmetauscher
bezeichnet werden, sind grundsätzlich
aus dem Stand der Technik bekannt, beispielsweise aus der
Aufgabe der Neuerung ist es, einen Wärmetauscher aufzuzeigen, der verbesserte Wärmeübertragungseigenschaften aufweist. Zur Lösung dieser Aufgabe ist ein Wärmetauscher entsprechend dem Schutzanspruch 1 ausgebildet.task the innovation is a heat exchanger show improved heat transfer properties having. To the solution This task is a heat exchanger formed according to the protection claim 1.
Der
wesentliche Aspekt des neuerungsgemäßen Wärmetauschers ist darin zu sehen,
dass die Trennwände
zumindest abschnittsweise eine entlang der Längsrichtung des Wärmetauschers
vorgesehene und aus mehreren Profilelementen bestehende Profilierung
aufweisen, wobei die Profilelemente abwechselnd von der Trennwandebene
nach innen und/oder außen
gewölbt
sind. Hierdurch wird innerhalb des durch die Trennwände gebildeten
Strömungskanals
eine unruhige Oberfläche
erzeugt, mittels der turbulente Strömungen innerhalb des Strömungskanals
Weiterbildungen der Neuerung sind Gegenstand der Unteransprüche.further developments the innovation are the subject of the dependent claims.
Die Neuerung wird im Folgenden anhand der Figuren an einem Ausführungsbeispiel näher erläutert. Es zeigen:The Innovation will be described below with reference to the figures of an embodiment explained in more detail. It demonstrate:
