Abstract: An ozone generator includes a container, a first metal electrode, a dielectric electrode, a heat pipe, a heat sink, and a power supply unit. The first metal electrode is a cylindrical electrode the axial direction of which is a first direction, and disposed in the container. A cooling medium is supplied to an outer peripheral surface thereof. The dielectric electrode is a cylindrical electrode that is disposed to be opposed to an inner peripheral surface of the first metal electrode, and is coaxial with the first metal electrode. The heat pipe is disposed to be opposed to an inner peripheral surface of the dielectric electrode, and has electrical conductivity. The heat sink is disposed on the outside as an outer space of a space between the first metal electrode and the heat pipe, and connected to the heat pipe.

Abstract: An ozone generation device includes an inverter, an ozone generator, and a reactor. The inverter turns on and off a switching element by pulse width modulation (PWM) control to convert DC power into AC power. In the ozone generator, voltage of the AC power is applied to a dielectric electrode, and discharge is generated in raw material gas flowing in a discharge gap between the dielectric electrode and a metal electrode, so that ozone is generated by the discharge. The reactor is connected in series to a dielectric electrode, and reduces an inrush current that flows through the dielectric electrode when the switching element is switched from off to on by the PWM control by the inverter.

Abstract: An ozone generator includes a metal electrode, a dielectric element, a conductive film, and a power feeding member. The dielectric element has a tubular shape and is spaced from the metal electrode with a discharge gap to which raw gas is supplied. The conductive film is located. on an inner surface of the dielectric element. The power feeding member is electrically connected to the conductive film, and includes a contact member of a mesh form including a plurality of woven metal wires. The contact member contacts with the conductive film.
