Heat Exchanger For An Air Supply Circuit Of A Motor Vehicle Engine

摘要

A heat exchanger (10′) for the air supply circuit of a motor vehicle engine, comprises a heat exchange core (100) and at least one header tank (210′). The heat exchanger (10′) comprises an air flow rate control valve (300) arranged in the header tank (210′) of the exchanger, and the control valve (300) is a valve comprising a body (310) with three openings (311; 313) and a moving rotary member (320) inside the body (310) so as to control the circulation of air through the heat exchange core (100) and/or through a duct (13′) bypassing the heat exchange core (100) according to a law defined as a function of the angular position of the rotary member (320) in the body (310). The heat exchanger (10′) is particularly applicable to motor vehicles with a supercharged engine.
