PREFERRED EMBODIMENT OF THE INVENTION

[0053] In view of the figures, a preferred embodiment of the proposed invention is described below.

[0054] The preferred embodiment described below relates to a cyclonic conversion generator, being the same principles applicable to an anti-cyclonic conversion generator, varying the elements arrangement but with the same necessary elements.

[0055] In FIG. 1 we can observe a cyclonic conversion generator comprising a hollow and rigid structure (1), at the top end of which it is arranged deflector diffusers (2).

[0056] The hollow and rigid structure is, preferably, cylindrical with an increasing section from the base to the top, with straight or curved walls in the form of a hyperbole. The deflector diffusers (2) protrude from the perimeter of the hollow structure (1) at its upper end, being disposed in a stepped way increasing toward the top end in order to form several concentric flows which produce a venturi effect on the output fluid.

[0057] The hollow structure (1) comprises an area with means for forming a secondary flow (4) or vortex core. In this case of cyclonic conversion, said means are at the base of the hollow structure (1).

[0058] On the rest of the hollow structure (1), generating means of the primary flow (3) are arranged.

[0059] Means for forming the primary flow (3) comprise convectors (5) that, as previously explained, will be at least two, but could be a number such as to cover the entire perimeter of the hollow structure (1). The input surface defined by each of the convectors, may be divided by a series of partitions or separators in the form of a slope (12) which is inclined to promote the upward rotation of the primary flow.

[0060] Said slopes (12) have an upward inclination and a reduced section as they penetrate inside the hollow structure.

[0061] The forming means of the secondary flow (4) or vortex core comprise a series of convectors (6) and can additionally have, as seen in FIG. 7, a projection or central convexity (11) of a uniform profile that promotes the upward movement of the secondary flow or vortex core.

[0062] In FIGS. 2 and 3, several convectors (5) for generating secondary flow are shown. In this case, the convectors (5) cover the entire perimeter of the hollow structure (1), since it is a fixed structure, so that they also have a blocking device (7) movable so as to leave always open at least two of the entries defined by two blocking devices.

[0063] Since the hollow structure (1) may be of several tens of meters, the blocking device shall have a length equal to the height of the hollow structure (1), so that, in order to manufacture and move such a large blocking device, the blocking device (7) can be divided into portions or sections (7.1), as shown in FIG. 5.

[0064] FIG. 6 shows how the electric generator is mounted in the hollow structure (1), the turbine (8) being provided in the central part supported by aerodynamic-section beams or supports (10) and said supports (10) including access paths to the turbine (8).

[0065] From the turbine (8), generating blades (9) emerge that makes it possible to reach almost the inner wall of the hollow structure (1) in order to achieve the maximum flow running through the structure.

[0066] Turbines may comprise three, five, seven or nine ducted blades (9), which will be adjusted as much as possible to the output vortex duct in order to obtain a maximum performance and, even, embedded in the tubular profile of the output vortex conduit. Efficiency may exceed 95% of the output vortex flow.

[0067] Regarding the type of generator to be used, multipolar permanent magnet generators (PMG) are preferable, because the starting torque is much lower than in conventional electromagnetic generators.

[0068] Once sufficiently described the nature of the present invention as well as implementation of the same, it has to be noted that, in its essence, it may be put into practice with another embodiments that may differ in detail from that indicated herewith by way of example, and which will also include the scope of protection, provided they do not alter, change or modify its fundamental principle.
