Title
(EN) HEAT TRANSFER CIRCUIT FOR A DRIVETRAIN
(FR) CIRCUIT CALOPORTEUR POUR GROUPE MOTOPROPUSLEUR
Abstract
(EN)
The invention relates to a drivetrain (1) comprising a heat engine (7), a turbocompressor (8), a pump (9), a water outlet housing (10), a radiator (3) and a fan heater (4) and a heat transfer circuit (11) in which a heat transfer fluid flows, comprising a first segment (14) positioned at the outlet of said heat engine (7) on which said turbocompressor (8) is mounted, and a second segment (15), connecting the water outlet housing (10) to said fan heater (4), characterized in that said heat transfer circuit (11) comprises a third segment (16) on which said pump (9) is mounted, having a third segment inlet located on the first segment (14), upstream of the turbocompressor (8) and a third segment outlet located on the second segment (15), said first segment (14) being connected to the third segment (16) downstream of said pump (9), and a check valve (30) is provided on said second segment (15) upstream of said third segment (16) outlet.
(FR)
L'invention concerne un groupe motopropulseur (1) comportant un moteur thermique (7), un turbocompresseur (8), une pompe (9), un boîtier de sortie d'eau (10), un radiateur (3) et un aérotherme (4) et un circuit caloporteur (11) dans lequel circule un fluide caloporteur, comportant un premier segment (14) positionné en sortie dudit moteur thermique (7) sur lequel est monté ledit turbocompresseur (8), et un second segment (15), reliant le boîtier de sortie d'eau (10) audit aérotherme (4), caractérisé en ce que ledit circuit caloporteur (11) comporte un troisième segment (16) sur lequel est montée ladite pompe (9), présentant une entrée de troisième segment située sur le premier segment (14) en amont du turbocompresseur (8) et une sortie de troisième segment située sur le second segment (15), ledit premier segment (14) étant relié au troisième segment (16) en aval de ladite pompe (9) et un clapet antiretour (30) est prévu sur ledit second segment (15) en amont de ladite sortie du troisième segment (16).
