Abstract

Beschrieben wird eine Vorrichtung zur Kühlung einer, einen Strömungskanal umgebenden Strömungskanalwand (3) mit wenigstens einem, in ein durch den Strömungskanal hindurchtretendes Strömungsmedium, Strömungswirbel induzierenden Rippenzug (4), der an der dem Strömungskanal zugewandten Seite der Strömungskanalwand (4) angebracht ist und eine Hauptlängserstreckung aufweist, die in einem Winkel α≠0 zur Strömungsrichtung (7) des durch den Strömungskanal hindurchtretenden Strömungsmediums orientiert ist.
Die Erfindung zeichnet sich dadurch aus, dass der Rippenzug (4) entlang der Hauptlängserstreckung wenigstens teilweise Rippenzugabschnitte aufweist, deren Rippenzugabschnittsachsen mit der Hauptlängserstreckung einen Winkel β≠0 aufweist.
