Abstract

Ein Schaufelträger für einen axial durchströmten Verdichter ist mit Kühlkanälen versehen, welche in geschlossenem Kreis von einem Kühlmittel durchströmt sind. Die Kühlkanäle verlaufen zumindest annähernd in Umfangsrichtung innerhalb des Schaufelträgers, und befinden sich in einem geschlossenen Wasserkreislauf, welcher im wesentlichen aus einer Umwälzpumpe (31), einem Druckhaltegefäss (32) und einem Wärmeaustauscher (35) besteht.
Die Kühlkanäle sind ringförmig angeordnet, wobei jeder Kühlring (27) mit einer Zuleitung (28) und einer Ableitung (29) versehen ist. In Längsrichtung des Schaufelträgers ist mindestens jeder zweite aufeinanderfolgende Kühlring an einen separaten Kühlpfad angeschlossen.
