OZONE GENERATOR

摘要

An ozone generator according to the present invention includes: three or more cooling channels having through-holes in the central portions thereof, and coolant passages therein, wherein the cooling channels are arrayed in parallel such that the through-holes overlap one another; and an electric discharge unit inserted in neighboring ones of the cooling channels to discharge electricity when high voltage is applied thereto. The electric discharge unit has a central hole in a portion corresponding to the through-holes. When high voltage is applied to the electric discharge unit, and the cooling channels are grounded, oxygen supplied to a side end of the electric discharge unit is decomposed to generate ozone that is discharged through an inner space defined by the through-holes and the central hole. An ozone generator according to the present invention comprises: an electric discharge unit that includes a conductor to which high voltage is applied, a dielectric having a surface covering the conductor, and a ground plate having a surface covering another surface of the dielectric; and a cooling channel including a coolant passage, and contacting another surface of the ground plate. The ground plate includes a protrusion on a surface facing the dielectric to form a space between the dielectric and the ground plate.
