In Fig. 6 ist die mäanderförmige Anordnung von zwei in einem Strömungskanal 8 spiegelbildlich zur Mittellinie angeordneten Kühlmittelkanälen 2 gezeigt. Zwischen den Kühlmittelkanälen 2 sind wiederum die Öffnungen 9 angeordnet. Im vorliegenden Beispiel erfolgt die parallele Längserstreckung der Kühlmittelkanäle 2 in einem spitzen Winkel in Förderrichtung 10. Alternativ ist auch diese Längserstreckung in einem stumpfen Winkel in Förderrichtung 10 realisierbar. In entsprechender Anordnung verlaufen auch die Mehrzahl an Öffnungen 9 zwischen den Kühlmittelkanälen 2. Durch diese Anordnung ist ein Ausstreichen der Bogen 15 erzielbar und eine mögliche dynamische Anregung des Bogens 15 ist vermeidbar. Weiterhin zeigt diese Ausbildung eine Parallelschaltung von zwei Kühlmittelkanälen 2 mit je einem Vorlauf 4 und einem Rücklauf 5 für das Kühlmittel in einem Strömungskanal 8 auf. Damit ist der Kühlmitteldurchsatz bei verbesserter Wärmeabfuhr deutlich erhöhbar.
