Abstract
A motor vehicle heating/air-conditioning system of a motor vehicle has a water-removal device arranged in the fresh-air inlet duct, rising from the duct base and comprising a coarse-mesh lattice and a fine-mesh lattice resting against the latter. The water removed is carried away downwardly on the webs of the coarse-mesh lattice to the duct base which forms a water collection point with water drainage. In order to combine a favorable water-removal function with a good air-guidance function, the coarse-mesh lattice facing the incident air represents an air guide with predetermined throughflow and is pleated in a corrugated shape. A channel spanned by the fine-mesh lattice arranged in at least some areas is in each case formed between two upwardly-directed corrugation troughs. The water-removal device is placed in the region of a duct widening provided by a set-back wall portion, such that the water-removal device ends at a distance from the set-back wall portion.
