Title
(EN) THERMAL MANAGEMENT DEVICE FOR THE BATTERIES OF AN ELECTRIC OR HYBRID MOTOR VEHICLE
(FR) DISPOSITIF DE GESTION THERMIQUE DES BATTERIES D'UN VÉHICULE AUTOMOBILE ÉLECTRIQUE OU HYBRIDE
Abstract
(EN) The invention relates to a thermal management device (1) for the batteries of an electric or hybrid motor vehicle, said thermal management device (1) comprising a first circulation loop (A) for a refrigerant fluid as well as a second circulation loop (B) for a heat-transfer fluid, said thermal management device (1) also comprising first (101) and second (102) bi-fluid heat exchangers arranged jointly on both the first (A) and second (B) circulation loops, said first circulation loop (A) comprising, in the direction of circulation of the refrigerant fluid, a compressor (13), the first bi-fluid heat exchanger (101), the second bi-fluid heat exchanger (102), a first expansion device (15) and a first heat exchanger (17) configured to exchange heat energy directly or indirectly with the batteries, the second circulation loop (B) comprising a pump (23), a second heat exchanger (27) configured to exchange heat energy with an external air flow (F1) and the second (102) and first (101) bi-fluid heat exchangers both arranged downstream of the second heat exchanger (27) in the direction of flow of the heat-transfer fluid.
(FR) Dispositif de gestion thermique (1) de batteries d'un véhicule automobile électrique ou hybride, ledit dispositif de gestion thermique (1) comportant une première boucle de circulation (A) d'un fluide réfrigérant ainsi qu'une deuxième boucle de circulation (B) d'un fluide caloporteur, ledit dispositif de gestion thermique (1) comportant également un premier (101) et un deuxième (102) échangeur de chaleur bifluide agencés conjointement à la fois sur la première (A) et la deuxième (B) boucle de circulation, ladite première boucle de circulation (A) comportant dans le sens de circulation du fluide réfrigérant, un compresseur (13), le premier échangeur de chaleur bifluide (101), le deuxième échangeur de chaleur bifluide (102), un premier dispositif de détente (15) et un premier échangeur de chaleur (17) configuré pour échanger de l'énergie calorifique directement ou indirectement avec les batteries, la deuxième boucle de circulation (B) comportant une pompe (23), un deuxième échangeur de chaleur (27) configuré pour échanger de l'énergie calorifique avec un flux d'air externe (F1) et les deuxième (102) et premier (101) échangeurs de chaleur bifluide tous deux disposés en aval du deuxième échangeur de chaleur (27) dans le sens de circulation du fluide caloporteur.
