Description

Device for fluids kinetic energy conversion

Technical field

In wider sense this invention belong to area of electro-energetic.

Technical problem Technical problem which is solved with this invention is how to make possible more efficient utilization fluids kinetic energy in open systems (kinetic energy of rivers, tides, oceanic currents, winds)? How to increase fluid flow velocity inside with tube framed apparatus (devices) for fluids kinetic energy conversion without adding outside energy?

Background art

Within applications P-2009/0054 and P-2011/0034 and P-2011/0102 it is already presented housing for framed and so called "ducted turbines" by which utilization fluid flow velocity trough turbine i.e. device for conversion of fluids flow kinetic energy is being increased. However in this application these concepts are further upgrading and advancing by adding additional framing vertical rings and half rings by which is created completely new concept of device for fluids kinetic energy conversion into electric energy.

Disclosure of Invention

The essence of the invention is reflected in the new concept of frame tubes for with tube-framed appliances to convert kinetic energy of fluids and new concept devices for converting the kinetic energy of fluids in open systems derived from the new concept of a frame tubes.

New concept of framing tube is consists of main framing tube with a funnel extensions at their ends.

At the output extension of the main framing tube is primary framing ring or half ring which is with the main tube connected via supporting vertical stabilizer. At the framing ring there are one, or more, vertical ring or half ring. At the framing ring could be placed and secondary vertical stabilizers. With additional (secondary) ring(s) i.e. half rings and/or with primary framing ring(s) i.e. half ring(s) could be integrated peripheral framing tubes which on its ends also have funnel extensions. Peripheral tubes dependably from application may be without extensions at its ends. New concepts of framing tubes represent conceptual improvement of framing tube concept described in application P-2009/0054.

Within additional option of new concept of framing tube vertical ring is connected directly with output extension at the primary framing tube. With additional vertical (secondary) ring(s) i.e. half rings and/or with primary framing ring(s) i.e. half ring(s) could be integrated peripheral framing tubes which on its ends also have funnel extensions. Peripheral tubes dependably from application may be without extensions at its ends.

By application of new framing tube concepts on the all appliances, which like the part of its functional whole consists with tube framed rotor or rotors, dramatic flow velocity increasing occur within framing tubes of such apparatus by which efficiency of these apparatus is being increased as well as the amount of fluid kinetic energy conversion into electric energy in unit of time.

New concepts of framing tubes functioning by regulating very complex flowing patterns trough appliances as well as around appliances.

However when elements of new concepts of framing tubes present functional parts of apparatus (appliances) for fluids kinetic energy conversion into electric energy, integrated with new concepts of framing tubes, than new concepts of framing tubes along with these apparatus make new concepts of devices for fluids kinetic energy conversion into electric energy.

Dependably of application with new concepts of framing tubes there could be integrated all apparatus which as functional essence of fluid kinetic energy conversion use with tube framed rotor or rotors like for example tube for conversion kinetic energy of fluid P-2006/O1 86 or electro-generator with role of tube turbine and drive propeller P-2008/0196 as well as many others devices which function on similar way.

During integration of mentioned apparatus with new concepts of framing tubes, main (primary) framing tube replacing framing tube of given apparatus while peripheral framing tubes at the primary framing ring (half ring) i.e. on secondary framing rings (if there is more framing rings -half rings) replacing framing tube of secondary apparatus for fluids kinetic energy conversion into electric energy.

On this way framing tubes of secondary apparatus, as well as fluid flows through these appliances, along with other functional parts of new concept of framing tube directly affect on fluid flow trough primary apparatus, which again, along with fluid flow around framing tube (main framing tube) of primary apparatus and all other elements directly affect fluid flow trough secondary apparatus by which is on one interdependent way increase the amount of fluid flow trough primary apparatus as well as trough secondary appliances by which is by large increased the efficiency of whole system (device) as well as the amount of electric energy production of device in all.

By different combinations of different kinds of apparatus for fluid kinetic energy conversion into electric energy which as a part of its functional whole have with tube framed rotor or rotors, as well as by different combinations (number, presence, dimensions, geometrical shapes) primary and secondary framing rings and half rings, secondary framing tubes and all other functional elements of new concepts of devices for fluid flow kinetic conversion, different kinds of new concept of device for fluids flow kinetic energy conversion into electric energy are being made.
