Title (EN) COOLANT FLUID CIRCUIT COMPRISING A CIRCULATOR
(FR) CIRCUIT DE FLUIDE REFRIGERANT COMPRENANT UN CIRCULATEUR
Abstract:
(EN) Circuit (100, 200, 300, 400, 500) for the coolant of a vehicle with at least partially electric propulsion, comprising at least:- a first sub-circuit (120, 220, 320, 420, 520) in which there are arranged at least one compressor (122, 222, 322, 422, 522), a first heat exchanger (124, 224, 324, 424, 524) and a first expansion member (126, 226, 326, 426, 526),-a second sub-circuit (140, 240, 340, 440, 540) in which there are arranged at least one second expansion member (142, 242, 342, 442, 542) and a second heat exchanger (144, 244, 344, 444, 544) associated with a drivetrain of the vehicle, -a third heat exchanger (162, 262, 362, 462, 562) common to the first sub-circuit (120, 220, 320, 420, 520) and to the second sub-circuit (140, 240, 340, 440, 540), the circuit (100, 200, 300, 400, 500) comprising a circulator (146, 246, 346, 446, 546) configured to generate an increase in coolant pressure of between 1 and 3 bar. Application to motor vehicles.
(FR) Circuit (100, 200, 300, 400, 500) de fluide réfrigérant pour véhicule à propulsion au moins en partie électrique, comprenant au moins : - un premier sous-circuit (120, 220, 320, 420, 520) dans lequel est agencé au moins un compresseur (122, 222, 322, 422, 522), un premier échangeur de chaleur (124, 224, 324, 424, 524) et un premier organe de détente (126, 226, 326, 426, 526), - un deuxième sous-circuit (140, 240, 340, 440, 540) dans lequel est agencé au moins un deuxième organe de détente (142, 242, 342, 442, 542) et un deuxième échangeur de chaleur (144, 244, 344, 444, 544) associé à une chaine de traction du véhicule, - un troisième échangeur de chaleur (162, 262, 362, 462, 562) commun au premier sous- circuit (120, 220, 320, 420, 520) et au deuxième sous-circuit (140, 240, 340, 440, 540), le circuit (100, 200, 300, 400, 500) comprenant un circulateur (146, 246, 346, 446, 546) configuré pour générer une élévation de la pression du fluide réfrigérant comprise entre 1 et 3 bars. Application aux véhicules automobiles.
