Abstract

Aufgabe der Erfindung ist es, eine einfache, mit einer verbesserten Kühlwirkung ausgestattete Vorrichtung und eine entsprechendes Verfahren zur Kühlung einer einseitig von Heissgas umgebenen Wand zu schaffen.
Erfindungsgemäss wird dies dadurch erreicht, dass stromauf jeder Reihe von Ausnehmungen (10) eine radiale Rippe (15) an der inneren Oberfläche (9) der Wand (3) angeordnet, der Kühleinsatz (4) im Bereich der Ausnehmungen (10) in Richtung der Wand (3) verformt und dabei zumindest annähernd parallel zum Eintrittswinkel (16) der Ausnehmungen (10) ausgebildet ist. Auf diese Weise wird das Kühlfluid (7) bereits vor Erreichen der Ausnehmungen (10) in deren Richtung umgelenkt und ein stabiles Innenwirbelpaar (19) erzeugt. Zudem werden die Eintrittsverluste verringert. Das nicht in die Ausnehmungen (10) strömende Kühlfluid (7) wird beschleunigt und der Wärmeübergang durch Prallkühleffekte erhöht. Im Kühlhohlraum (5) zwischen zwei Ausnehmungen (10) angeordnete Abstandshalter (20) oder Stifte (21) dienen als Wärmesenkelemente, um den Bereich bis zur lateralen Verbindung zweier Kühlluftstrahlen zu verbessern.
