Abstract

A bladeless bubble fan includes a housing defining a plurality of inlets and having enclosed therein an impeller for drawing air through the inlets from an exterior thereof, at least a portion of the housing forming a closed geometrically shaped outer shell and defining an axial passageway therethrough. An inner air guide is received in the housing and coaxial with the closed geometrically shaped outer shell and in combination with the outer shell defines a plenum therebetween in fluidic communication with an output of the impeller and further defines a peripheral outlet of the plenum. A bubble ring is affixed to the inner air guide and coaxial therewith. The bubble ring has a plurality of closely spaced fins extending inwardly toward an axis of the axial passageway.
