Abstract

L'invention porte sur un dispositif de refroidissement, lequel dispositif est apte à empêcher une déformation due à la pression interne d'un agent de refroidissement en phase vapeur, sans provoquer une augmentation du poids. Un dispositif de refroidissement selon la présente invention comprend : un récipient plan qui comporte une première plaque plate et une seconde plaque plate ; et un agent de refroidissement qui est hermétiquement scellé dans le récipient plan. La première plaque plate et/ou la seconde plaque plate ont une structure en relief.
