Device for producing artificial snow, and method for producing artificial snow

摘要

A device for producing artificial snow includes: elements (100) for producing a central jet (101) consisted by a first fluid chosen among air or water; elements (110) for producing a peripheral jet (111) consisted by a second fluid chosen among water or air and different from the first fluid; and nucleation elements (120) for the production of at least one nucleation jet (121). The elements for producing the central jet and the elements for producing the peripheral jet are arranged in such a manner that the opposite contours (103, 114) of their respective jets each define a generating line, which opposite generating lines extend parallel or at least approximately parallel to each other; moreover, the nucleation elements (120) are distributed over the external periphery of the elements (110) for producing the peripheral jet (111).

1. A device for producing artificial snow, the device comprising:
a central jet system configured to produce a central jet consisting of a first fluid chosen among air or water, said central jet including an external contour and an axis of projection; a peripheral jet system configured to produce a peripheral jet consisting of a second fluid chosen among water or air and being different from said first fluid, said peripheral jet having a generally tubular shape defining an internal contour and an axis of projection, said peripheral jet being projected over the whole or substantially the whole periphery of said central jet; and a nucleation jet system configured to produce at least one nucleation jet to form crystals of ice, to produce artificial snow from the cooperation of said central and peripheral jets, wherein the central jet system and the peripheral jet system are configured such that the opposite contours of the respective jets each define a generating line, the generating lines of each of the respective jets defining between each other an angle of between −5° and 5°, at least in an initial portion thereof, following production thereof, the nucleation system is distributed over the external periphery of the peripheral jet system, and an axis of projection of the nucleation jet of the nucleation system defines a convergent angle of between 0° and 15° with respect to the axis of projection of the central jet.
