The invention relates to a device for effecting heat transfer to rotating equipment, in particular gas turbines. A gas turbine (10) comprises a first rotating unit (11), i.e. an internal shaft and a second fixed unit (16), i.e. a housing. A third rotating unit (14, 17), i.e. rotor blades and plates connected to said rotor blades are disposed between the first unit (11) and the second unit (16). Said first (11) and third (14, 17) units are rotatable around a common axis (12) and with respect to each other. According to said invention, at least one device (21) for improving heat transfer by convection is assigned to the first rotating unit (11), i.e. the internal shaft.
L'invention concerne un dispositif destiné à influencer la transition thermique dans des appareils rotatifs, notamment des turbines à gaz. Une turbine à gaz (10) comporte un premier groupe rotatif (11), c.-à-d. un arbre intérieur, ainsi qu'un deuxième groupe fixe (16), c.-à-d. un boîtier. Un troisième groupe rotatif (14, 17), c.-à-d. des aubes mobiles, et des plaquettes affectées aux aubes mobiles, sont disposés entre le premier groupe (11) et le deuxième groupe (16) le premier groupe (11) et le troisième groupe (14, 17) pouvant tourner autour d'un axe commun (12) et l'un par rapport à l'autre. Selon l'invention, au moins un dispositif (21) destiné à améliorer la transition thermique par convexion est affecté au premier groupe rotatif (11), c.-à-d. à l'arbre intérieur.
