Patent ID: 8424203

Claim:
A method of manufacturing a thermal protection device comprising: inserting a first porous, fluid and gas permeable wick structure, having a first hollow chamber fluid and gas permeably connected to and disposed within the first porous, fluid and gas permeable wick structure, within a shell; and inserting a second porous, fluid and gas permeable wick structure, having a second hollow chamber fluid and gas permeably connected to and disposed within the second porous, fluid and gas permeable wick structure, within the shell so that each of the first and second porous, fluid and gas permeable wick structures and the first and second hollow chambers are fluid and gas permeably connected, and disposing a porous, fluid and gas permeable wick lid member within the shell between the first, porous, fluid and gas permeable wick structure and the second, porous, fluid and gas permeable wick structure, such that an opening is disposed between the first hollow chamber and the second hollow chamber.
