Abstract

Die Anmeldung betrifft einen Plattenwärmetauscher in asymmetrischer Ausführung, mit einem Stapel von Wärmeübertragungsplatten, mit denen gegeneinander abgeschlossene Durchgänge für Wärmetauscherfluide gebildet sind, wobei die Wärmeübertragungsplatten eine Profilierung (2) aufweisen, die mit einer Anordnung von aus der Plattenebene (4) hervorstehenden Pyramidenstümpfen (3) und hierzwischen in der Plattenebene (4) angeordneten Basisabschnitten (5) gebildet ist, und die Durchgänge asymmetrisch, nämlich unterschiedliche Volumenströme zulassend ausgeführt sind, indem bei benachbarten Wärmeübertragungsplatten in dem Stapel von Wärmeübertragungsplatten die Basisabschnitte (5) einer oberen Wärmeübertragungsplatte auf den Pyramidenstümpfen (3) einer darunter liegenden Wärmeübertragungsplatte angeordnet sind.

The application relates to a plate heat exchanger in asymmetric design, with a stack of heat transfer plates, with which mutually closed passages for heat exchange fluids are formed, wherein the heat transfer plates have a profiling (2) with an array of from the plate plane (4) protruding truncated pyramids (3 4), and the passages are made asymmetrical, namely permitting different volume flows, by placing the base sections (5) of an upper heat transfer plate on the truncated pyramids (3) on adjacent heat transfer plates in the stack of heat transfer plates. 3) of an underlying heat transfer plate are arranged.
