Abstract

Eine Prallkühlung für Wandteile (10) zeichnet sich durch eine Mehrzahl von Prallrohren (11) aus, die mit ihrem Einlauf (12) flächenförmig auf einem ebenen oder gekrümmtem Träger (13) angeordnet sind und mit ihrer Mündung (14) gegen den zu kühlenden Wandteil (10) gerichtet sind, wobei der Träger mit Abstand (20) zum Wandteil angeordnet ist.

Figure 00000001
Impingement cooling for wall parts (10) is characterized by a plurality of impingement tubes (11), which are arranged with their inlet (12) in a flat manner on a flat or curved support (13) and with their mouth (14) against the wall part to be cooled (10) are directed, the carrier being arranged at a distance (20) from the wall part.
