Injection molding apparatus for producing an atomizer

Representative embodiments provide for corresponding fluid atomizer bodies, each generally defining a fluidicly communicative interior cavity. The interior cavity is typically defined by an entry passageway portion, a chamber portion, a plurality of feeder passageways that are tangentially disposed to and fluidly coupled with the chamber portion, and an exit passageway portion fluidly coupled to the chamber portion. In one embodiment, an upper body portion and a lower body portion are bonded together to define a complete fluid atomizer body. Another embodiment provides for producing one or more fluid atomizer bodies by a way of injection molding. A method provides for spraying or sputtering atomized droplets of an electrically non-conductive coolant onto an electrical apparatus using one or more fluid atomizer bodies.
