| 英文摘要 | A high-resolution microsatellite's focal plane components have high heat flux and a long working time. In order to solve the heat-dissipation problem of a microsatellite's focal plane components under the condition of narrow space, this paper uses a new type of ultralight and super-high thermal conductivity Pyrolytic Graphite Sheet to make a thin and flexible thermal conduction strip. Such a strip is used to design the thermal control scheme for a fully passive, modular, and fast integration of the focal plane components. Analysis and test results show that under the conditions of an installation space of 0.5mm and the mass of the thermal conduction strip of 20g, the focal plane components work continuously for 600s; the maximum temperature of the CMOS (Complementary Metal-Oxide-Semiconductor) sensor is 31.8 degrees C. Five groups of CMOS sensors had a temperature nonuniformity no higher than 1 degrees C. The application of the new PGS (Pyrolytic Graphite Sheet) provides a new solution for the related space thermal design. |
