차세대 중형위성 전자광학 탑재체 카메라 제어기 전장품의 열적 안정성 평가

Abstract

CCB (Camera Controller Box) is an electronic equipment to perform acquisition, processing and transmitting imaging data of electro-optical camera for CAS (Compact Advanced Satellite). The electronic equipment for satellite applications shall maintain its reliability in entire mission duration because the satellite is almost impossible to be repaired or recovered after launch. To guarantee a reliability of electronics during its mission life time, a junction temperature of EEE (Electric, Electronic and Electromechanical) parts is important design parameter and shall be secured within their allowable ranges. In addition, a heat flux density from the electronic equipment to the satellite shall be within its design requirement. In this study, we performed the thermal analysis of the CCB to assess its thermal stability with respect to the junction temperatures of each components as well as the heat flux density. The thermal analysis results indicated that a thermal design of CCB fully satisfies the required thermal stability.
