Vehicle interior ventilation system has an air collection box with a smaller air outflow than inflow and an inner deflection bar to separate water from the air flow by deflection for a longer air filter life

摘要

The fresh air feed system into the interior of a vehicle has an air collection box (20) with an inlet and outlet (18,19) and an air deflection bar (24) for the separation of water by the air flow deflection. The air outflow (19) has a smaller size than the air inlet (18). A number of spaced and parallel dividing walls (27) are between the air deflection bar (24) and a box wall (201), on the side of the deflection bar (24) away from the air filter (25). The dividing walls (27) extend from a point near the air inlet (18) to the free end of the air flow deflection bar (24).
