Abstract

L'invention concerne un changeur de chaleur du type comportant des tubes à coude de retour, traversés par un fluide et interposés en vue d'un échange de chaleur sur le trajet d'un autre fluide, l'agencement étant tel qu'en service, une branche de chacun desdits tubes est plus chaude que l'autre. L'invention propose deux agencements grâce auxquels les contraintes subies du fait de dilatations thermiques par les coudes de retour ne sont pas plus grandes à chaud qu'à froid. Application échangeurs divers notamment pour Installations nucléaires.The invention relates to a heat exchanger of the type comprising return elbow tubes through which a fluid passes and interposed for the purpose of heat exchange on the path of another fluid, the arrangement being as in use. , one branch of each of said tubes is hotter than the other. The invention proposes two arrangements thanks to which the stresses undergone due to thermal expansions by the return elbows are not greater when hot than when cold. Application of various exchangers in particular for nuclear installations.
