Abstract

Vorrichtung zur Kühlung einer einen Strömungskanal (4) umgebenden Strömungskanalwand (1) mit wenigstens einem, in ein, durch den Strömungskanal (4) hindurchtretendes Strömungsmedium, Strömungswirbel induzierenden Rippenelement (2,3), das an der, dem Strömungskanal (4) zugewandten Seite der Strömungskanalwand (4) angebracht ist und dessen Form und Größe unter Massgaben eines bestimmten Wärmeübergangskoeffizienten sowie eines bestimmten, durch das Überströmen des Rippenelementes (2,3) mit dem Strömungsmedium in diesem verbundenen Druckverlust gewählt sind, wobei das Rippenelement (2,3) unter weitgehendem Beibehalten seiner ursprünglichen Form und/oder Größe, seine, dem Strömungskanal (4) zugewandte Oberfläche vergrössernde Konturen aufweist.

Figure 00000001
Device for cooling a flow channel wall (1) surrounding a flow channel (1) with at least one rib element (2, 3) which induces flow vortices in a flow medium which passes through the flow channel (4) and which is on the side facing the flow channel (4) the flow channel wall (4) is attached and its shape and size are selected in accordance with a certain heat transfer coefficient and a certain pressure loss associated with the flow medium due to the overflow of the fin element (2, 3), the fin element (2, 3) below largely maintaining its original shape and / or size, its surface facing the flow channel (4) has enlarging contours.
