Abstract

Ozone generator cells that include two thermally conductive plates that maintain contact between various layers of the cells in the absence of a bonding agent. The cells lack aluminum-containing materials in the discharge region of the cell.

First claim

The invention claimed is:

1. An ozone generator comprising:
an ozone generator cell comprising:
a high voltage electrode layer,
a first dielectric layer and a second dielectric layer, the high-voltage electrode being disposed between the first dielectric layer and the second dielectric layer,
a first low voltage electrode layer and a second low voltage electrode layer, the high-voltage electrode, the first dielectric layer and the second dielectric layer being disposed between the first low voltage electrode layer and the second low voltage electrode layer,
a first discharge region and a second discharge region, the high voltage electrode layer being disposed between the first discharge region and the second discharge region, and
a first thermally conductive plate and a second thermally conductive plate, the high-voltage electrode, the first dielectric layer, the second dielectric layer, the first low voltage electrode layer, the second low voltage electrode layer, the first discharge region, and the second discharge region being disposed between the first thermally conductive plate and the second thermally conductive plate;
a base plate over which the ozone generator cell is positioned; and
a spring-loaded clamp plate coupled to the base plate such that the ozone generator cell is disposed between the base plate and the spring-loaded clamp plate, such that the coupled base plate and spring-loaded clamp plate apply pressure to the ozone generator cell to hold the high-voltage electrode, the first dielectric layer, the second dielectric layer, the first low voltage electrode layer, and the second low voltage electrode layer of the ozone generator cell together.

2. The ozone generator of claim 1 , wherein the coupled base plate and spring-loaded clamp plate apply pressure to the ozone generator cell to hold the high-voltage electrode, the first dielectric layer, the second dielectric layer, the first low voltage electrode layer and the second low voltage electrode layer of the ozone generator cell together in the absence of a bonding agent.

3. The ozone generator of claim 2 , wherein the absence of the bonding agent results in the ozone generator cell having reduced thickness.

4. The ozone generator of claim 3 , wherein the reduced thickness produces an increased capacitance between the low voltage electrode layers and the high voltage electrode layer.

5. The ozone generator of claim 1 , wherein the two dielectric layers, the two low voltage electrode layers, and the high voltage electrode layer are all fabricated using non-aluminum containing materials.

6. A method of fabricating an ozone generator, comprising:
fabricating an ozone generator cell, comprising:
locating a high voltage electrode layer between a first dielectric layer and a second dielectric layer,
locating the high voltage electrode layer, the first dielectric layer and the second dielectric layer between a first low voltage electrode layer and a second low voltage electrode layer,
locating the high voltage electrode layer between a first discharge region and a second discharge region, and
locating the high-voltage electrode, the first dielectric layer, the second dielectric layer, the first low voltage electrode layer, the second low voltage electrode layer, the first discharge region, and the second discharge region between a first thermally conductive plate and a second thermally conductive plate;

locating the ozone generator cell over a base plate; and
coupling a spring-loaded clamp plate to the base plate such that the ozone generator cell is disposed between the base plate and the spring-loaded clamp plate, such that the coupled base plate and spring-loaded clamp plate apply pressure to the ozone generator cell to hold the high-voltage electrode, the first dielectric layer, the second dielectric layer, the first low voltage electrode layer, and the second low voltage electrode layer of the ozone generator cell together.

7. The method of claim 6 , wherein the coupled base plate and spring-loaded clamp plate apply pressure to the ozone generator cell to hold the high-voltage electrode, the first dielectric layer, the second dielectric layer, the first low voltage electrode layer and the second low voltage electrode layer of the ozone generator cell together in the absence of a bonding agent.

8. The method of claim 7 , wherein the absence of the bonding agent results in the ozone generator cell having reduced thickness.

9. The method of claim 8 , wherein the reduced thickness produces an increased capacitance between the low voltage electrode layers and the high voltage electrode layer.

10. The method of claim 6 , wherein the two dielectric layers, the two low voltage electrode layers, and the high voltage electrode layer are all fabricated using non-aluminum containing materials.
