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.A device for cooling a surrounding a flow channel is described Flow channel wall (3) with at least one, in one through the flow channel flowing medium, flow vortex-inducing rib train (4), the side of the flow channel wall (4) facing the flow channel is attached and has a main longitudinal extension at an angle α ≠ 0 to the flow direction (7) of the flow medium passing through the flow channel is oriented.
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. The invention is characterized in that the rib train (4) has at least partially rib train sections along the main longitudinal extension, the rib train section axes of which have an angle β ≠ 0 with the main longitudinal extension.
