Abstract:
1. A motor vehicle comprising a body having a floor panel and an engine compartment defined in the front part of the body, a liquid-cooled engine, supported by the body inside the engine compartment, a radiator forming part of the cooling system of the engine and set in front of the engine compartment, and a fan facing the radiator at the rear, wherein a conveyor structure is provided for the air that has traversed the radiator and the fan, in the form of a monolithic tubular duct, with a widened cylindrical mouth that surrounds the fan completely behind the radiator, said duct extending downwards from said mouth to a vertically flattened portion that starts at the bottom area of the fan and that extends longitudinally towards the rear of the vehicle, so as to end in an outflow mouth set underneath the floor panel, on the outside of the floor panel, in order to reduce the aerodynamic resistance of the motor vehicle, preventing the passage of a considerable flow of air longitudinally through the engine compartment and conveying the flow at outlet from the radiator underneath the floor panel of the motor vehicle and longitudinally along it, said vertically flattened portion of the conveyor structure being horizontally widened towards the rear of the vehicle.
