Abstract
A passive cryocooler has been developed for the cooling of small payloads to temperatures as low as 145 K. Although designed for a specific electronics experiment on the STRV-1d microsatellite, the device is suitable for a wide range of applications. The cryocooler uses coated surfaces for tailored radiative cooling. Mechanical support between components is provided by fiberglass struts. The measured end temperature reached is 151 K in a liquid nitrogen dewar which extrapolates to an end temperature of lower than 145 K in space. Thermal vacuum testing and random vibration testing at levels consistent with an Ariane 5 launch have been performed as part of formal qualification for the STRV mission. In this paper, details of the design, analysis, fabrication and testing of the passive cryocooler are presented.
