Nozzle head for producing snow crystals has main body, head, nozzle hole connected to water-feeder pipe. and nozzle opening and cavitation chambers

摘要

The nozzle head has at least one nozzle (6) for atomizing water and which has a main body (4) positioned in the head (2) in which is a nozzle hole (10) connected to a water-feeder pipe (22). At least one cavitation chamber is positioned in the nozzle body between a nozzle opening (38) and the water-feeder pipe. The cavitation chamber is coaxial with the nozzle opening and widens out radially in relation to the nozzle. The cavitation chamber has a first larger-diameter cavitation chamber (34) next to the nozzle opening, and a second, smaller-diameter, cavitation chamber (36) next to the feeder opening
