FIELD: electricity.
SUBSTANCE: axial fan unit of electric machine includes axial fan wheel (6), inlet channel (1) limited by internal partition (2) and separation partition (3), and drain channel (7) limited by separation partition and external partition (8). According to invention, the inlet channel houses rectifying blade aggregate (4) and guide blade aggregate (5), where guiding blade aggregate (5) is installed before axial fan wheel (6).
EFFECT: enhanced performance of fan unit, reduced ventilation losses, higher efficiency and lower axial dimension of turbogenerator.
