Abstract: The micro-atomizing device of the present invention creates high energy vortices. These high speed vortices are generated simultaneously and synchronously and then merged into a three dimensional force field. When the high energy vortices are brought together, a large vacuum is produced in a resultant stable vortex force field in a vortex accumulation zone. The high vacuum draws the fluid to be atomized through a delivery tube into the vortex accumulation zone. The high energy within the vortex accumulation zone either breaks up the fluid to be atomized into very small droplets or gasifies the fluid by the combination of high energy density cold boiling, shockwave generated ultrasound, and centripetal forces.
