Abstract
A gas replenishment component for an electronic enclosure is described. A main body defines a containment volume. The main body is sealed about the containment volume. A charging gas is contained in the containment volume. The containment volume has less than 5% N2. The main body defines a diffusive area that is permeable to the gas. A reversible seal obstructs the diffusive area.
Claims16
A gas replenishment component for an electronic enclosure, comprising:
- a main body constructed of a polymer defining a containment volume, wherein the main body is sealed about the containment volume;
- and
- a charging gas contained in the containment volume, wherein the charging gas comprises O2, wherein the main body defines a diffusive area that is permeable to the charging gas, and a non-diffusive area, wherein the diffusive area has a permeability that is at least double the permeability of the non-diffusive area relative to the charging gas, and wherein the polymer has a first thickness defining the diffusive area and the polymer has a second thickness defining the non-diffusive area, and the first thickness is less than the second thickness.
A method of constructing a gas replenishment component comprising:
- forming a main body sealed about a containment volume, wherein the main body is constructed of a polymer and defines a diffusive area that is permeable to a charging gas, and a non-diffusive area, wherein the diffusive area has a permeability that is at least double the permeability of the non-diffusive area relative to the charging gas, and wherein the polymer has a first thickness defining the diffusive area and the polymer has a second thickness defining the non-diffusive area, and the first thickness is less than the second thickness;
- charging the containment volume with the charging gas, wherein the charging gas comprises O2;
- and
- sealing the main body about the containment volume and the charging gas.
