Title (EN) INTEGRATED HEAT EXCHANGER AND COOLANT CONTROL VALVE AND METHOD OF OPERATING THE SAME
(FR) ÉCHANGEUR DE CHALEUR INTÉGRÉ ET SOUPAPE DE COMMANDE DE LIQUIDE DE REFROIDISSEMENT ET SON PROCÉDÉ DE FONCTIONNEMENT
Abstract:
(EN) A heat management system in a vehicle includes an engine, a vehicle radiator fluidly coupled to the engine by an engine coolant line for routing an engine coolant from the vehicle radiator to the engine during at least one mode of operation. The system also includes a transmission and a transmission oil heat exchanger fluidly coupled to the transmission by a transmission fluid line for routing a transmission fluid between the transmission and the transmission oil heat exchanger during second and third modes of operation. Additionally, the system includes a switch valve assembly integrated with the transmission oil heat exchanger. Moreover, during a first mode of operation the transmission fluid bypasses the transmission oil heat exchanger and is routed from the transmission through the switch valve assembly and back to the transmission for avoiding heat loss which occurs when the transmission fluid is moved through the transmission oil heat exchanger.
(FR) L'invention concerne un système de gestion de chaleur dans un véhicule. Ce systéme comprend un moteur, un radiateur de véhicule couplé de manière fluidique au moteur par une ligne de refroidissement de moteur pour acheminer un liquide de refroidissement de moteur du radiateur de véhicule au moteur pendant au moins un mode de fonctionnement. Le système comprend également un échangeur de chaleur d'huile de transmission couplé de manière fluidique à une transmission par une ligne de fluide de transmission pour acheminer un fluide de transmission entre ces deux composants pendant des deuxième et troisième modes de fonctionnement. Le système comprend en outre un ensemble soupape de commutation intégré à l'échangeur de chaleur d'huile de transmission. De plus, pendant un premier mode de fonctionnement, le fluide de transmission contourne l'échangeur de chaleur d'huile de transmission et est acheminé depuis la transmission à travers l'ensemble soupape de commutation et vers la transmission afin d'éviter une perte de chaleur qui se produit lorsque le fluide de transmission est déplacé à travers l'échangeur de chaleur d'huile de transmission.
