Embodiment Construction

[0080] figure 1 Schematic showing the process of making snow with artificial snow using a snow spray gun. Ice nuclei 28 are generated in nucleation nozzles 20 or 50 . Water droplets 32 are produced in the water nozzle 30 . The water droplets 32 move to the crystal growth region E through the drop section 31 . The ice nuclei 28 move to the crystal growth region E through the ice nucleation section 21 . In the crystal growth region E, water droplets 32 come into contact with ice nuclei and grow into crystal grains. On the way through the drop section 31 , the water droplets 32 atomized by the water nozzles 30 are cooled. The water droplets growing together with the ice nuclei then condense in the condensation zone 40 and, after a drop height H of about 10 meters, usually turn into snow and fall to the ground.

[0081] figure 2 A cross-sectional view of the nucleation nozzle 20 of the present invention is shown. The nucleation nozzle 20 has a lateral water inlet 22 and an...

Abstract

A nucleator nozzle (20) for producing ice nuclei is designed as convergent-divergent nozzle. The nozzle channel (25) has a section (27) that is widening. The ratio of the cross-sectional area of the outlet opening (23) to the cross-sectional area of the nozzle channel (25) in the region of the nucleus diameter (26) is at least approximately 4:1. A snow lance (1) having at least one nucleator nozzle (20) and having at least one water nozzle (30,30') is designed such that water droplets (32) produced by the water nozzle (30,30') pass through a droplet path (31,31') of at least 20 cm until they reach ice nuclei (28) from the nucleator nozzle (20) in a germination zone E.

Description

technical field [0001] The present invention relates to a mechanism for producing ice nuclei and artificial snow, in particular a nucleating nozzle, the use of the mechanism, a device, a snow gun and a method according to the preamble of the independent claims. Background technique [0002] Artificial snow has been known for a long time. Snow guns or snow cannons are currently used in various forms especially in the field of winter sports. According to a known method, an ice nucleation jet is generated in a "nucleation nozzle" and brought into contact with a water droplet jet consisting of water droplets. Through so-called "crystallization growth", snow composed of cold water is produced. [0003] To create ice nuclei, water is cooled and atomized by using compressed air. A key factor for the economical operation of such nucleation nozzles is the amount of compressed air that has to be used in order to achieve the desired effect. The amount of compressed air determines t...
