Liquid metal/air heat exchanger

Creators

Description

The aim of the invention is a liquid metal/air heat exchanger which can resist to thermal expansion of tubes for which a supporting system is provided in the present case; this supporting system does not involve excessive stresses. Such heat exchangers apply to LMFBR type reactors. They are used as emergency heat exchangers when there is a failure of the reactor cooling circuits to cool the primary liquid sodium, or as heat exchangers in test or experimental circuits of reactors

Abstract (French)

Le but de l'invention est un echangeur de chaleur metal liquide/air qui peut supporter des dilatations importantes et variables des tubes pour lesquels on a prevu un supportage qui n'entraine pas de contraintes excessives. On utilise de tels echangeurs comme echangeurs de chaleur de secours lors d'une defaillance des circuits normaux de refroidissement d'un reacteur a neutrons rapides pour le refroidissement du sodium liquide primaire, ou comme echangeurs de chaleur dans les circuits d'essai ou dans les circuits experimentaux des reacteurs nucleaires. Ce brevet nous donne la description technique d'un tel echangeur de chaleur
