Abstract

L’évaporateur (23) d’un circuit récupérateur de chaleur (24) adjoint à un circuit de refroidissement (14) d’un moteur thermique (13) est disposé sur une dérivation (18) d’un conduit de sortie (16) hors du moteur, et une vanne (17) commande la répartition des flux caloporteurs entre la dérivation (18) et la portion parallèle du conduit (16). Le débit passe complètement ou principalement par la dérivation (18) quand le moteur est chaud, mais pas quand il est froid, afin de rendre alors l’évaporateur (23) inactif et de ne pas contrarier une montée en température normale du moteur (13). En plaçant l’évaporateur (23) juste à la sortie du moteur (13), on dispose d’un débit maximal du fluide caloporteur parcourant le circuit de refroidissement (14) et donc d’une récupération plus efficace de la chaleur. Figure pour l’abrégé : F ig. 2 .
