As heat generation in satellites increases, securing sufficient radiator panel area is an important problem. Deployable radiator, whose radiator panels are deployed post-launch in space to increase the effective radiator panel area of the satellite, is becoming an important thermal control technology. Reservoir Embedded Loop Heat Pipe (RELHP) is applied to the deployable radiator for heat transport device. Deployable radiator for use on Kiku-8 was launched on December 18, 2006 and was injected to the geostationary orbit. It is still in operation without any significant issues since its launch over two years ago. This paper presents the heat transport characteristics of RELHP for use on deployable radiator under geostationary orbital environment. RELHP has been succeeded in start-up under micro gravity environment. Furthermore, it was found that, in case of under micro gravity environment sub-cooling region length is shorter than under gravity environment, because of heat leak into reservoir decreases under micro gravity environment.
