Abstract

The present invention relates to a wind tower (10) for delivering wind flow to a turbine. The wind tower (10) including includes a support structure (12) mounted to a support surface (14) and a stackable wind intake section 16 rotatably mounted to the support structure (12) and elevated with respect to the support surface (14). The intake section (16) having a central aperture (28) and includes a plurality of internal passageways (32) extending between a plurality of wind-facing inlets (22) and a plurality of outlets (34). The plurality of inlets (22) are orientated for concurrently receiving an oncoming wind-flow W. Each of the inlets (22) are in fluid communication with one of the outlets 34 via one of the passageways (32) and the outlets are arranged around and in fluid communication with the central aperture. The wind tower (10) further includes an output passageway (42) for collecting wind flow W from the plurality of outlets (34). The output passageway (42) is in fluid communication with the outlets (34) and extends downwardly from the intake section (16) toward the support surface (14) for delivering wind flow W to a turbine located at or proximate to the support surface (14). By being stackable, the wind tower size can be tailored to suit a particular geographic location or when the wind direction varies by altitude. The central aperture and surrounding inlets of the wind intake section provides more evenly distributed wind intake and prevents flow constriction from occurring, thereby increasing wind tower efficiency.

Claims (2)

The claims defining the invention are as follows:
1. A wind tower for delivering wind flow to a turbine including: • a support structure mounted to a support surface; • a stackable wind intake section rotatably mounted to the support structure and elevated with respect to the support surface, the intake section having a central aperture and a plurality of internal passageways separated by a plurality of internal partitions and extending between a plurality of wind-facing inlets oriented for concurrently receiving an incoming wind-flow across the width of the stackable intake section and a plurality of outlets, each of the inlets being in fluid communication with one of the plurality of outlets and the outlets being arranged around and in fluid communication with the central aperture, with the central aperture being of lesser diameter than the total width of the inlets to concentrate wind flow captured across a wider area via one of the passageways, wherein all of the plurality of wind-facing inlets are orientated for concurrently receiving an oncoming wind-flow; and • an output passageway for collecting wind flow from the plurality of outlets, the output passageway being in fluid communication with the outlets and extending downwardly from the intake section toward the support surface for delivering wind flow to a turbine located at or proximate to the support surface.
2. A wind tower according to claim 1 including a plurality of wind intake sections arranged in a stacked configuration and a downpipe associated with a lowermost intake section in the plurality of intake sections receives wind flow from each of the other intake sections in the plurality of intake sections. 20270704_1 (GHMatters) P109511.NZ
