Optimum Seal Fixture Design for Sealing Gas Panels

Various fixtures are used in the making of gas panels to seal the glass plates. The gas panel requirements are such that a uniform seal is necessary to produce a stable display with long life. The drawing shows an optimized seal fixture design.

The thermal properties and strength of the materials used in this design have the best combination of physical and thermal characteristics to achieve good seals in gas panels. The actual physical design is based on both mathematical and empirical models. The box shape employed reduces the thermal gradients found in open fixture designs. The periphery of the fixture was found to have the greatest thermal gradients and required additional mass. Because lava retains its flatness at elevated temperatures (500 degrees C) and the aluminum has excellent thermal conductivity, these materials were found best suited for this optimized seal fixture.

This composite box-shaped seal fixture provides high temperature stability, good thermal conductivity, and a small thermal gradient across the glass gas panel plates.
