Abstract

With the resolution of space CCD camera enhancing, the demand of temperature stability of CCD components becomes tight. The traditional thermal products, such as heat pipe, could not satisfy the temperature control precision. A Temperature-controlling loop heat pipe (TCLHP) using silicon nitride capillary wick is designed and produced successfully, which is used for thermal control of CCD components in satellite GF-9. Flight data indicated that the temperature precision was better than ±0.4 °C. It was the first time for Chinese home-grown loop heat pipe used for the thermal control of spacecraft in microgravity conditions, of which design method and flight data could provide a reference for the use of loop heat pipe in space.
