Title (EN) A cooling system in a hybrid vehicle
(FR) SYSTÈME DE REFROIDISSEMENT POUR UN VÉHICULE HYBRIDE
Abstract:
(EN) The present invention relates to a cooling system for a hybrid vehicle (1) powered by a combustion engine (2) and an electrical machine (3). The cooling system comprises a first circuit (4) with a first circulating coolant which is cooled in a first radiator (7) before it cools the combustion engine (2), a second circuit (11) with a second circulating coolant which is cooled in a second radiator (19) to a lower temperature than the first coolant before it cools the electrical machine (3), and a refrigerant circuit (16), The cooling system comprises a third circuit (20) with a third circulating coolant cooled by refrigerant in a chiller (25) of the refrigerant circuit (16) to a lower temperature than the second coolant before it cools an electrical energy storage (18) and a cab space (33) in the vehicle (1).
(FR) La présente invention concerne un système de refroidissement pour un véhicule hybride (1) alimenté par un moteur à combustion (2) et une machine électrique (3). Le système de refroidissement comprend un premier circuit (4) avec un premier réfrigérant en circulation refroidi dans un premier radiateur (7) avant de refroidir le moteur à combustion (2), un deuxième circuit (11) avec un second réfrigérant en circulation refroidi dans un second radiateur (19) à une température inférieure à celle du premier réfrigérant avant de refroidir la machine électrique (3), et un circuit de réfrigérant (16). Le système de refroidissement comprend un troisième circuit (20) avec un troisième réfrigérant en circulation refroidi par un réfrigérant dans un refroidisseur (25) du circuit de réfrigérant (16) à une température inférieure à celle du second réfrigérant avant de refroidir un stockage d'énergie électrique (18) et un espace de cabine (33) dans le véhicule (1).
