Abstract

Described is a ventilation unit (1) where an open motor (4) rotationally drives a hub (13) equipped round the outside of it with a plurality of first blades (12) forming an axial fan (27); the motor (4) is at least partially housed in the hub (13) and defines with the latter an air space (15) that forms part of a fluid dynamic circuit (22) for a flow (F1) that cools the motor (4); the cooling flow (F1) is produced by a secondary fan (21) that comprises a plurality of second blades (19), is built into the hub (13) inside the hub (13) itself and is coaxial with the fan (27) formed by the first blades (12).
