Abstract (en)

The heat exchanger consists of a fin (6) to go in a tube (2) of a heat exchanger with fluid flowing through it. The fin is corrugated in cross section, creating parallel flow channels (8). There are also recesses (10) in the individual valleys or apexes of the corrugations, connecting at least one flow channel with at least one other, not directly adjacent, flow channel.

Abstract (de)

Die vorliegende Erfindung betrifft eine Rippe (6), insbesondere für ein Rohr (2) eines mit Fluid durchströmten Wärmetauschers bzw. Kondensators. Die Rippe (6) ist im Querschnitt im wesentlichen wellenförmig ausgebildet, wodurch im Rohr (2) mehrere im wesentlichen parallel verlaufende Strömungskanäle (8) ausgebildet werden. Ferner ist die Rippe (6) mit Vertiefungen (10) versehen, durch die mindestens einer der Strömungskanäle (8) mit mindestens einem weiteren, nicht direkt benachbarten Strömungskanal (8) verbunden ist. Unabhängig von den Vertiefungen kann Fluid durch jeden einzelnen der Strömungskanäle strömen. Durch diese Konstruktion des Rohrs läßt sich der Wirkungsgrad beispielsweise eines Wärmetauschers oder Kondensators erheblich verbessern. <IMAGE>
