Abstract

L'invention porte sur un échangeur de chaleur à tubes parallèles recevant d'une nourrice commune un flux de réfrigérant à deux phases et comportant à une extrémité de la nourrice une buse d'éjection obligeant le réfrigérant à traverser l'une des branches de la nourrice puis à revenir par l'autre branche et de nouveau dans la première branche à l'aide d'un tube de pontage. Cette disposition permet d'obtenir une distribution plus uniforme du réfrigérant dans les tubes parallèles. Dans une exécution, la nourrice est faite d'un seul tube présentant une cloison centrale longitudinale délimitant deux chambres s'étendant longitudinalement et communiquant par des ouvertures situées aux deux extrémités de la cloison.
