Abstract

L'invention est du domaine des échangeurs thermiques. Dans l'échangeur selon l'invention, les tubes à double paroi 5 sont montés, d'une part, dans une plaque tubulaire simple 7 et, d'autre part, dans deux plaques tubulaires espacées 9, 11, la paroi intérieure 21 des tubes 5 étant reliée de façon étanche à la plaque tubulaire extérieure, tandis que la paroi intérieure 23 est reliée de la même façon à la plaque tubulaire intérieure 9, les parois extérieures 23 étant reliées hermétiquement à leurs jonctions intérieure et extérieure avec la plaque tubulaire unique 7. Application à la détection des fuites avant le mélangeage des deux fluides en échange de chaleur.
