Abstract

An ozone generation cell has a first conductor generally having a line geometry and a second conductor having a first groove formed in a surface thereof, and having first and second flanks on opposite sides of the first groove. The second conductor and the first groove are arranged such that the first groove follows the first conductor in parallel spaced-apart relation. The ozone generation cell also has a first dielectric having a first passage-defining portion positioned between the first conductor and the first groove. The first dielectric has first and second side portions on opposite sides of the passage-defining portion that are generally parallel to the first and second flanks respectively. The first passage-defining portion is spaced-apart from only one of the first conductor and the first groove to form a first fluid passageway defined in part by the first passage-defining portion.

Claims

1. An ozone generation cell comprising:

a first conductor generally having a line geometry;

a second conductor having a first groove formed in a surface thereof, and having first and second flanks on opposite sides of said first groove, said second conductor and said first groove being arranged such that said first groove follows said first conductor in parallel spaced-apart relation; and

a first dielectric having a first passage-defining portion positioned between said first conductor and said first groove and said first dielectric having first and second side portions on opposite sides of said passage-defining portion and generally parallel to said first and second flanks respectively;

said first passage-defining portion being spaced-apart from only one of said first conductor and said first groove to form a first fluid passageway defined in part by said first passage-defining portion, for conducting fluid from which ozone may be obtained when an electric field of sufficient strength is produced in said first fluid passageway by a potential applied across said first and said second conductors.

2. The ozone generation cell of claim 1 further comprising a heat sink adjacent said first groove.

3. The ozone generation cell of claims 2 wherein said second conductor includes said heat sink.

4. The ozone generation cell of claim 3 wherein said heat sink extends on at least one side of said first groove.

5. The ozone generation cell of claim 3 wherein said heat sink extends on both sides of said first groove.

6. The ozone generation cell of claim 1 wherein said first conductor has a solid cross-section.

7. The ozone generation cell of claim 1 wherein said first conductor has a generally circular-shaped cross-section.

8. The ozone generation cell of claim 1 wherein said first conductor has a generally oval-shaped cross-section.

9. The ozone generation cell of claim 1 wherein said first conductor has a generally rectangular-shaped cross-section.

10. The ozone generation cell of claim 1 wherein said first conductor has a generally “

C”

-shaped cross-section.

11. The ozone generation cell of claim 1 wherein said first conductor has a conduit extending therethrough.

12. The ozone generation cell of claim 1 wherein said first groove has a first groove surface that is generally concentric with a longitudinal axis of said first conductor.

13. The ozone generation cell of claim 1 wherein said first groove surface is disposed at a generally uniform distance from an outer surface of said first conductor.

14. The ozone generation cell of claim 1 wherein said first passage-defining portion comprises a first parallel surface spaced-apart from said first groove by a generally uniform depth distance.

30. The ozone generation cell of claim 29 wherein said grooves of said plurality of grooves are generally parallel to each other.

31. The ozone generation cell of claim 29 wherein said second conductor has a conduit extending therethrough, for conducting fluid to said grooves.

32. The ozone generation cell of claim 31 further comprising a first fluid flow director for directing fluid from said conduit to said groves.

33. The ozone generation cell of claim 32 wherein said cell includes a second fluid flow director for directing fluid from one groove to another groove.

34. The ozone generation cell of claim 1 further comprising a third conductor having a second groove formed in a surface thereof, and having third and fourth flanks on opposite sides of said second groove, said third conductor and said second groove being arranged such that said second groove follows said first conductor in parallel spaced-apart relation;
