Problems solved by technology

[0005] Horizontal axis turbines have the disadvantage of requiring a large amount of installation space and being characterized by high mechanical complexity
[0015] However, such solutions are also not very efficient aerodynamically, since the side edges of the opening are at right angles and as inlets allow neither good nor high flow rates

Abstract

A vertical axis wind turbine (100) comprising a rotor (110) having a substantially vertical rotation axis z, said rotor (110) comprising a plurality of blades (111) arranged to rotate about its rotation axis z in consequence of the aerodynamic drag opposed to an air flow investing said blades (111). The wind turbine (100) also comprises a casing structure (120) in which the rotor (110) houses. The casing structure (120) comprises a lower plate (121) substantially orthogonal to the rotation axis z, said lower plate (121) defined by a first plurality of vertices V1,...,Vn, an upper plate (122) substantially orthogonal to the rotation axis z, said upper plate (122) defined by a second plurality of vertices V1',...,Vn', each vertex V1',...,Vn' of the second plurality corresponding to a vertex V1,...,Vn of the first plurality. The casing structure (120) also comprises a plurality of walls (125a-125d) arranged to connect the lower plate (121) and the upper plate (122), said walls (125a-125d) and said plates (121,122) defining a plurality of openings (126a-126d) arranged to work as inlet / outlet of said air flow into / from said casing structure (120). Each wall (125a-125d) is defined by one edge (127a-127d) that connects a vertex V1,...,Vn of the first plurality with a corresponding vertex V1'...,Vn' of the second plurality. The edge (127a-127d) is protruding outwards from the casing structure (120) with respect to a plurality of vertical ideal lines V1-V1',..., Vn-Vn' joining the vertex V1,...,Vn of the first plurality with the corresponding vertex V1',...,Vn' of the second plurality.

Description

technical field [0001] The invention relates to the field of wind turbines. [0002] In particular, the invention relates to the field of vertical axis wind turbines with casing structures or nacelles. Background technique [0003] Depending on the rotor orientation, wind turbines can be subdivided into two categories: horizontal axis turbines and vertical axis turbines. [0004] An example of a horizontal axis turbine is a windmill in which the axis of rotation of the rotor is arranged substantially aligned with the prevailing airflow direction. Typically, the axis of rotation is in turn generally rotatable about a vertical axis in order to achieve and / or maintain alignment of the axis of rotation of the rotor with the prevailing airflow direction. In such machines, all blades are shrouded by the airflow at the same time, and all blades actively participate in the rotation of the rotor. [0005] Horizontal-axis turbines have the disadvantage of requiring a large amount o...
