Ozone generator having a conductor with projections extending through an inner electrode and associated fabrication method

摘要

An ozone generator includes an inner electrode formed of a mass of helical windings through which an elongate electrical conductor extends. The elongate conductor is preferably a metal strip having opposing rows of sawtooth projections extending outwardly from opposing side edges of the strip. The metal strip also preferably has a generally sinuous shape in longitudinal cross-section. An outer electrode is separated from the inner electrode by a dielectric tube. The inner and outer electrodes produce ozone gas using an electrical corona discharge in the presence of an oxygen containing gas. A second tube surrounds the first dielectric tube to capture ozone generated at the outer electrode. A pair of endcaps directs gas flow adjacent the outer conductor and through the inner conductor.
