Patent ID: 6866829

Claim:
An ozonizer comprising: at least one electrode module, electrode modules being stackable upon each other, each electrode module comprising laminated; a flat plate-shaped low voltage including a cooling water passage and an ozone passage inside said low voltage electrode; a flat plate-shaped high voltage electrode facing said low voltage electrode; a spacer located between said low voltage electrode and said high voltage electrode, defining a discharge gap between said low voltage electrode and said high voltage electrode; and a thermally conducting and electrically insulating sheet disposed on said high voltage electrode; a manifold block disposed on said low voltage electrode and having passages for circulating water through said cooling water passage and a passage for extracting ozone from said discharge gap through said ozone passage; and an electrode cooling sheet disposed on said thermally conducting and electrically insulating sheet and on said manifold block, at an outermost side of said electrode module, for cooling said high voltage electrode.
