Abstract

The invention relates to an air duct arrangement ( 100 ), in particular a charge air duct for a turbocharged engine, having an inlet air duct ( 60 ), a cooler ( 10 ) with an inlet ( 37 ) and an outlet ( 38 ), the cooler ( 10 ) having at least one air flow path portion ( 12, 14, 16, 18 ) extending between the inlet ( 37 ) and the outlet ( 38 ) along a longitudinal elongation ( 66 ) of the cooler ( 10 ) and having an outlet aperture ( 13, 15, 17, 19 ), and at least two runners ( 22, 24, 26, 28 ) of an air intake manifold ( 20 ) of an engine ( 40 ). The cooler ( 10 ) is arranged between the inlet air duct ( 60 ) and the runners ( 22, 24, 26, 28 ). Each runner ( 22, 24, 26, 28 ) has an inlet aperture ( 23, 25. 27, 29 ) and the outlet ( 38 ) of the cooler ( 10 ) is providing connection interfaces ( 73, 75, 77, 79 ) for the inlet apertures ( 23, 25. 27, 29 ) of the runners ( 22, 24, 26, 28 ).
