Title (EN) DEVICE AND METHOD FOR COOLING A THERMAL MEMBER IN AN AUTOMOBILE
(FR) DISPOSITIF ET PROCEDE DE REFROIDISSEMENT D'UN ORGANE THERMIQUE DE VEHICULE AUTOMOBILE
Abstract:
(EN) The invention relates to a cooling device (1) that includes a main cooling circuit (2) capable of adjusting the temperature of a thermal member (4), a secondary cooling circuit (3) including a first assembly (9) of at least two heat exchangers (10, 11) mounted in parallel, and a thermal coupling means (5) between the main cooling circuit (2) and the secondary cooling circuit (3). The cooling device (1) further comprises a temperature sensor (13) mounted in series on the secondary cooling circuit (3) and downstream from the first assembly (9), and a control unit including a first means capable of estimating, with a state monitor, the outlet temperature of each heat exchanger of the first assembly from the inlet temperature of a coolant at the inlet of each heat exchanger of the first assembly and from the values measured by the sensor temperature (13).
(FR) Le dispositif de refroidissement 1 comprend un circuit de refroidissement principal 2 apte à réguler la température d'un organe thermique 4, un circuit de refroidissement secondaire 3 comprenant un premier ensemble 9 d'au moins deux échangeurs de chaleur (10, 11) montés en parallèle, et un moyen de couplage thermique 5 entre le circuit de refroidissement principal 2 et le circuit de refroidissement secondaire 3. Le dispositif de refroidissement 1 comporte en outre un capteur de température 13 monté en série sur le circuit de refroidissement secondaire 3 et en aval du premier ensemble 9, et une unité de contrôle comprenant un premier moyen capable d'estimer avec un observateur d'état, la température de sortie de chaque échangeur de chaleur du premier ensemble à partir de la température d'entrée du fluide caloporteur en entrée de chaque échangeur de chaleur du premier ensemble et des grandeurs mesurées par le capteur de température 13.
