Abstract

Dispositif de refroidissement magnétothermique d’une turbomachine Un aspect de l’invention concerne un dispositif de refroidissement magnétothermique R3’ comprenant une paroi 1’’’ d’une turbomachine délimitant une zone de refroidissement Zr et une zone à température élevée Zc, une ouverture 2 traversant la paroi 1’’’ et une valve thermomagnétique 3’’’’ comprenant une membrane 30’’’ mobile entre une position fermée obturant au moins partiellement l’ouverture 2 et une position ouverte, et au moins un aimant permanent 31, produisant une force magnétique de la membrane 30’’’ vers la paroi 1’’’, dans lequel au-delà d’une température prédéterminée de la zone de température élevée Zc, la membrane est apte à avoir une température supérieure à une température déterminée entraînant une perte magnétique réversible de la membrane, telle que la force de l’aimant est inférieure à une force exercée sur la membrane 30’’’ vers la position ouverte pour passer la membrane 30’’’ de la position ouverte vers la position fermée.
