Abstract

Ein Wärmeaustauscher umfaßt mindestens zwei im wesentlichen parallele Rohrteile (2), die an ihrer Außenseite mit Rippen (3) versehen sind und durch im wesentlichen bogenförmige Verbindungsstücke (5) kaskadenartig miteinander verbunden sind. Erfindungsgemäß sind die Rohrteile (2) und die Verbindungsstücke (5) in einem Gehäuse untergebracht, das zumindest eine mit Hohlräumen versehene Deckplatte (7) aufweist, wobei primäre Hohlräume (8, 8') zur Aufnahme von Rohrteilen (2) eingerichtet sind, und sekundäre Hohlräume (9) zur Aufnahme von Verbindungsstücken (5) eingerichtet sind. Dadurch erzielt man einen sehr guten Wärmeaustausch. Vorzugsweise weist das Gehäuse ferner eine gleichfalls mit primären und/oder sekundären Hohlräumen (8, 8', 9) versehene zusätzliche Deckplatte (7') auf, so daß die Hohlräume der Deckplatten (7, 7') im montierten Zustand einander gegenüberliegen. Es ist vorteilhaft, die Rohrteile (2) und die Verbindungsstücke (5) als Ganzes zu formen.

Figure 00000001
A heat exchanger comprises at least two substantially parallel pipe parts (2) which are provided with ribs (3) on the outside and which are connected to one another in a cascade manner by essentially curved connecting pieces (5). According to the invention, the pipe parts (2) and the connecting pieces (5) are accommodated in a housing which has at least one cover plate (7) provided with cavities, primary cavities (8, 8 ') being set up for receiving pipe parts (2), and secondary cavities (9) for receiving connectors (5) are set up. This results in a very good heat exchange. The housing preferably also has an additional cover plate (7 '), which is also provided with primary and / or secondary cavities (8, 8', 9), so that the cavities of the cover plates (7, 7 ') lie opposite one another in the assembled state. It is advantageous to form the pipe parts (2) and the connecting pieces (5) as a whole.
