Abstract

Dispositif de refroidissement d'un moteur thermique, notamment pour véhicule automobile, comprenant un conduit de culasse 1 et un conduit de carter-cylindres 2 séparés et aptes à refroidir la partie du moteur correspondante, le dispositif de refroidissement présentant un circuit principal 5 comprenant au moins trois composants, le conduit de culasse 1, un radiateur 8 et une pompe principale 3 de circulation de fluide caloporteur, les trois composants étant raccordés entre eux par des portions du circuit principal, et un circuit secondaire 9 comprenant le conduit de carter-cylindres 2 et une pompe secondaire 4 de circulation. Le circuit secondaire 9 est raccordé au circuit principal 5 par deux jonctions voisines 10, 11 sur une même portion du circuit principal 5.
