The invention relates to an air-cooled ozone generator of tubular type which has a tubular outer electrode, a tubular dielectric, for instance of glass, arranged inside the outer electrode, and an inner electrode in the form of a metal coating on the inner side of the dielectric. The outer electrode and the dielectric are spaced apart and the resulting intermediate annular gap forms a discharge space in which oxygen is converted to ozone. The ozone generator is operated by means of a low-voltage, high-frequency AC source connected to the electrodes. The outer electrode has cooling flanges, and inside the inner electrode there is provided at least one heat dissipating metal body insertable in the inner electrode and expandable to abutment against the inner electrode. Preferably, the metal body also serves as an electric connection for connecting the inner electrode to the voltage source. The metal body preferably consists of a sheet formed into a cylinder with two inwardly directed flanges.
A gas-cooled ozone generator having paired tubular concentric electrodes and a solid dielectric disposed therebetween, characterized in that the outer electrode is provided with cooling flanges and spaced from the dielectric such that an annular gap is formed, that the axial ends of said gap are sealed by annular spacers, that the dielectric and the inner electrode have open ends to allow throughflow of cooling gas, and that cooling of the dielectric and of the inner electrode is effected by means of at least one expandable body which is disposed inside the inner electrode, against which the body abuts, and which is open to throughflow of cooling gas, said body comprising a sheet formed into a cylinder with two inwardly directed flanges.
An ozone generator comprising an outer tubular electrode having external flanges adapted for dissipating heat to ambient gases,
A portable ozone generator comprising an outer tubular electrode having external flanges adapted for dissipating heat to ambient gases,
