Abstract
A method and apparatus for protecting a heat sensitive component from high temperature, mechanical shock and moisture are provided. An enclosure includes an outer housing surrounding an inner cavity configured to receive a heat sensitive component therein, a cover configured to matingly engage the outer housing such that the inner cavity is sealed from an environment external to the enclosure, wherein at least one of the outer housing and the cover are formed from a ceramic material.
Claims8
A method of crash protecting a component, said method comprising:
- forming a housing of a first ceramic material, the housing including a cavity configured to receive a component;
- forming a cover of a second ceramic material, the cover configured to matingly engage the housing such that the cavity is sealedly surrounded by ceramic material;
- lining the cavity with a thermal insulation layer, wherein the thermal insulation layer is adjacent to an inner surface of the housing and the cover, and wherein the thermal insulation has a coefficient of thermal expansion approximately equal to a coefficient of expansion of at least one of the first ceramic material and the second ceramic material, the approximately equal coefficients of thermal expansion prevent gaps from forming between at least two of the housing, the cover, and the thermal insulation layer;
- positioning the component within the cavity;
- and
- joining the housing and the cover such that a mating engagement of the housing and the cover seals the cavity from an environment external to the housing and the cover.
