FAN Russian patent published in 2012 - IPC F04D25/08 

FIELD: ventilation.

SUBSTANCE: vaneless fan 100 for creation of the air flow includes nozzle 1 installed on the housing of base 16 for creation of the air flow passing through it. Nozzle 1 has internal channel 10 for receiving the air from base 16 and outlet hole 12 through which the air flow is discharged. Nozzle 1 is essentially located orthogonally to the axis and forms hole 2 through which the air is injected from outer side of fan 100 due to the air flow leaving the outlet hole 12. Both nozzle 1 and base 16 have the depth in the direction of axis; at that, depth of base 16 does not exceed double depth of nozzle 1. As an alternative, fan 100 has the height measured from the end of base 16, which is the most distant from nozzle 1, to the end of nozzle 1, which is the most distant from base 16, and width which is perpendicular to the height. At that, both the height and the width are perpendicular to the axis, and width of base 16 does not exceed 75% of nozzle 1 width.

EFFECT: fan has compact design.
