COOLING AXIAL FAN WITH AXIPETAL GUIDE BLADES OF THE STATOR Russian patent published in 2017 - IPC F01P5/06 F04D29/54 F04D19/00 

FIELD: ventilation.

SUBSTANCE: power generating plant contains a motor and an alternator driven by the mentioned motor for generating electrical power. The radiator and axial fan is connected to the motor, which directs the air to the radiator for its cooling. The stationary blades are placed between the axial fan and radiator. Each of the stationary blades contains the inner end and the outer end, at that the inner ends of the stationary blades are interconnected. The stationary blades are curved in a plane perpendicular to the axis of rotation to direct the air toward the axis, thereby offsetting the effect of centrifugal forces. The stationary blades can be twisted. The blade angle increases from 0° at the hub to 45° at the outer end. Furthermore, each stationary blade is attached to the stationary outer ring by means of the element, outgoing axially, due to which between the outer rim and the stationary blades is provided axially offset.

EFFECT: efficiency of the cooling system increase, fan revolutions drop.
