ELECTRODE FOR A DBD PLASMA PROCESS

摘要

A planar electrode for the DBD plasma treatment of a surface comprises a metal casing (8) raised to a high voltage and provided with an active part (2) intended to be placed in parallel with a surface to be treated (27). This active part (2) is covered on the outside by a sheet (4) of dielectric material to which it is fixed by a polymer layer (6). The internal face of the active part (2) forms with the metal casing (8) a heat exchanger connected to a secondary cooling circuit (34) through which a refrigerant (10) circulates.
