| 摘 要： | 在东方红一3卫星平台的基础上，将合理简化后的南蓄电池舱作为热分析模型。根据影响蓄电池温度波动的机理，提出服务舱舱板内表面常用热控涂层（白漆、镀铝膜、碳蒙皮）的5种组合方案，并量化分析了热控涂层红外发射率对蓄电池温度波动的影响。分析结果表明：降低蓄电池舱舱板内表面热控涂层红外发射率，尤其是降低蓄电池安装舱板表面的热控涂层红外发射率，可有效减小蓄电池温度波动幅度。与基准方案相比，最优组合方案能使蓄电池温度波动幅度降低50％。

| Abstract: | Based on DFH-3 satellite platform, the simplified south satellite battery cabin is presen- ted as the thermal analysis model. According to the mechanism of battery temperature variation, five combination schemes, in which the thermal control coatings of white paint,aluminized kapton and graphite-epoxy facesheet are used for inner panel of service module board, are proposed and used to analyze the effect of thermal control coatings infrared emittance on battery temperature. The analysis results show that the range of battery temperature variation can be reduced effectively by decreasing the thermal control coatings infrared emittance of inner panel in battery cabin, especially decreasing the thermal control coatings infrared emittance of fixing panel in battery cabin. The range of battery temperature variation in optimization scheme is decreased by 50% than that in original design scheme. |
