Abstract: A device for regulating an air stream for an air inlet of a motor vehicle may include a duct defining a flow channel in which an air stream flows. A cooling unit is arranged in the duct and includes at least one heat exchanger and a motor-fan unit. Additionally, the duct includes at least one sound absorption means arranged so that it at least partially limits the propagation of noise annoyance to the outside of the duct. A motor vehicle may include the regulation device.

Abstract: The invention relates to a device (1) for regulating an air stream for an air inlet of a motor vehicle, comprising a duct (2) defining a flow channel (4) in which an air stream flows, in which a cooling unit (6) is arranged comprising at least one heat exchanger (8, 10) and a motor-fan unit (12). According to the invention, the duct (2) comprises at least one sound absorption means (70) arranged so that it at least partially limits the propagation of noise annoyance to the outside of the duct (2). The invention also relates to a motor vehicle comprising such a regulation device (1).
