Abstract

A paddle wheel type ventilator for cooling towers etc., is made in the form of a ring which rotates around an axis through its centre, being rotated by a forced applied at its periphery. The rim may consist of sets of stacked rings with blades between the pairs of rings. These may be set at an angle in plan view and may slope in end view. Alternatively, each layer or ring may be made of zig-zag strip with the sloping sided portions fitting inside one another with gaps between. In another design, the zig-zag strips are crenellated with the square portions of one layer staggered on those of those underneath. In another design, each layer consists of overlapping internesting sloping sided portions.
