Abstract

Dans une structure de tuyauterie d'un dispositif de refroidissement dans un système d'ébullition et de refroidissement, lorsqu'un tuyau est flexible, la performance de refroidissement du dispositif de refroidissement est réduite. De ce fait, cette structure de tuyauterie d'un dispositif de refroidissement comporte une première partie tubulaire dotée d'une pièce creuse par laquelle circule un réfrigérant utilisé dans le dispositif de refroidissement, la première pièce tubulaire est constituée d'un matériau métallique, et la rugosité de surface d'une surface intérieure de la première pièce tubulaire ne dépasse pas la taille d'un noyau de condensation du réfrigérant.
