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.
