Design of vent reduces radiative transfer of heat. Venting system allows gases to escape while minimizing loss of heat by radiation. Prevents excessive buildup of internal pressure on thermal blanket. Polyimide box serves as modular vent. Many modules combined to suit gas-flow requirements of equipment. Indirect flow paths, external thermal control film, and thermal blankets reduce radiative loss of heat from interior. Developed to permit outgassing from thermal-blanket-covered spacecraft during passage from atmosphere of Earth to vacuum of space, venting approach adaptable to thermal insulation in laboratory vacuum systems.
