Abstract

The utility model relates to an intermediate-frequency ozone generation device which comprises an ozone generation pipe and a power circuit. The ozone generation pipe comprises a sealed outer shell. An inner shell is arranged inside the outer shell. A gap between the outer shell and the inner shell is communicated with a cooling water inlet and a cooling water outlet.
