DEVICE AND METHOD FOR COOLING A THERMAL MEMBER IN AN AUTOMOBILE

摘要

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).
