Abstract

Le dispositif de refroidissement (1) permet de refroidir rapidement et de façon homogène une surface chauffée (10) à une température supérieure à la température de vaporisation du fluide de refroidissement. Il comprend au moins un ensemble de deux tubes imbriqués (2), avec : . un tube interne (4), percé d'ouvertures (8) et connecté à une entrée de liquide (12); et. un tube externe (3), connecté à une sortie de vapeur (16) et s’étendant contre la surface à refroidir et autour du tube interne, de sorte à ménager dans le tube externe un volume intermédiaire (5) autour du tube interne. Le fluide de refroidissement entre à l’état liquide dans le tube interne et traverse les ouvertures pour passer dans le volume intermédiaire où il se vaporise. Une paroi hélicoïdale (20) est préférentiellement disposée dans le volume intermédiaire pour guider le fluide de refroidissement gazeux jusqu'à la sortie de vapeur. Figure pour l’abrégé : Fig 1
