Abstract
An air moving device includes a housing member, an impeller assembly, and a nozzle assembly. The nozzle assembly can include one or more angled vanes set an angle with respect to a central axis of the air moving device. The air moving device can output a column of moving air having an oblong and/or rectangular cross-section. A dispersion pattern of the column of moving air upon the floor of an enclosure in which the air moving device is installed can have an oblong and/or rectangular shape. The dimensions of the dispersion pattern may be varied by moving the air moving device toward or away from the floor, and/or by changing the angles of the stator vanes within the nozzle assembly.
Claims15
An air moving device comprising:
- a housing;
- an impeller rotatably mounted within the housing to cause movement of a volume of air through the housing;
- a nozzle defining a nozzle axis and having a nozzle inlet and a nozzle outlet positioned further from the impeller than the nozzle inlet, wherein a cross-sectional area of the nozzle outlet is less than a cross-sectional area of the nozzle inlet, and a nozzle housing defining a nozzle interior between the nozzle inlet and the nozzle outlet;
- a cross-vane having an upstream end and a downstream end, the cross-vane separating the nozzle interior into a first nozzle chamber and a second nozzle chamber;
- a first stator vane positioned at least partially within the first nozzle chamber, the first stator vane having an upstream end at the impeller and a downstream end at the outlet end;
- a second stator vane positioned at least partially within the first nozzle chamber, the second stator vane having an upstream end at the impeller and a downstream end at the outlet end;
- and
- wherein the upstream end of the first stator vane is bent at a first angle with respect to the nozzle axis and a remainder of the first stator vane, wherein the upstream end of the second stator vane is bent at a second angle with respect to the nozzle axis and a remainder of the second stator vane.
