摘要： Herein described is an axial fan for cooling the underhood of a farm machine, of the type made up of a rotor (10) provided with a plurality of blades (12) with a wing profile and a substantially radial development constrained against the central hub (14) of the rotor (10) at one of their first ends. Each blade (12) is made up of a first element or main profile (18) and by at least a second element or flap (20) arranged in proximity to the inlet edge (18') of the first element or main profile (18). A blading profile of such type allows pitch setting the blades with considerable angles of attack and obtaining high dynamic values, avoiding the occurrence of separations of the boundary layer from the top layer of the blade profile itself at the same time.

摘要： Disclosed is an axial fan for blowing air, for an electric fan, heater, or the like. Compared to existing models, for the same diameter and rotational speed, the disclosed axial fan produces a greater area and volume of air flow in front of the axial fan. Also, the axial fan can be manufactured using a two-piece mold, making mass production easy, while maintaining the strength of the fan itself The axial fan is provided with: a rotating shaft part attached to the rotating shaft of a rotational drive means; a set of internal blades provided coaxially with and to the outside of the rotating shaft part; and a set of external blades provided coaxially with and to the outside of the set of internal blades. The set of internal blades comprises a plurality of internal blades provided radially around the rotating shaft part, and the set of external blades comprises a plurality of external blades provided radially around the rotating shaft part. The numbers, areas, angles, and shapes of the internal blades and external blades are designed such that the speed V 1 of the airflow formed by the set of internal blades and the speed V 2 of the airflow formed by the set of external blades satisfy the relation 1.5V 1 2
