Protective enclosure and method for protecting heat sensitive, data recording devices in high temperature environments. The protective enclosure has a housing having at least one compartment for containing a heat sensitive, data recording device, e.g., a temperature recording device, and a jacket configured to contain a phase change material. The jacket may be vented and configured to at least partially surround the compartment. The housing may be sealed with an endcap. The recording device and a heat absorbing element are disposed within the same or within adjoining or adjacent sub-compartments within the enclosure. In a method, the enclosure with heat absorbing element and temperature recording device is placed within a heated environment or environment to be heated, e.g., a furnace. The recording device is connected to a thermal couple.

1. A protective enclosure comprising: a housing having an internal surface and an external surface; a compartment within the housing for containing a least one heat absorbing element and at least one device to be protected, the compartment having a compartment external wall, a compartment internal wall and a compartment insulation layer disposed between the external compartment wall and the internal compartment wall; a jacket within the housing defined by an internal volume between at least a portion of the housing internal surface and the external compartment wall, the jacket configured to contain a liquid phase change material within the internal volume and to at least partially surround the compartment; and a vent operatively connected to the jacket and configured to release the liquid phase change material to an environment external to the housing when the liquid phase change material vaporizes. 2. The enclosure of claim 1, wherein the heat absorbing element comprises a phase change material. 3. The enclosure of claim 1, wherein the compartment is comprised of a first subcompartment for containing the device to be protected and a second subcompartment for containing the at least one heat absorbing element, the first and second subcompartments being adjacent to one another. 4. The enclosure of claim 1, wherein the heat absorbing element comprises a solid-solid phase change material or a solid-liquid phase change material. 5. The enclosure of claim 1, wherein the compartment is comprised of a plurality of subcompartments. 6. The enclosure of claim 1, wherein the compartment comprises at least three adjacent subcompartments, one subcompartment containing the device to be protected, and two of the at least three subcompartments containing a heat absorbing element. 7. The enclosure of claim 1, further comprising an endcap to seal an open end of the housing. 8. The enclosure of claim 1, wherein the housing has a housing external wall, a housing internal wall, and a housing insulation layer disposed between the housing external wall and the housing internal wall. 9. The enclosure of claim 1, wherein the compartment has a plurality of heat absorbing elements and one or more devices to be protected disposed within the compartment.
