摘要
根据嫦娥三号'玉兔'巡视器总体构形特点和任务过程中的环境条件,提出了巡视器月昼散热和月夜保温热控设计思路,具体描述了巡视器月昼朝天散热和月夜利用两相流体回路、同位素热源进行设备保温的热控设计方法。经过热平衡试验验证和在轨飞行验证,热控分系统的各项功能和性能均满足总体要求,设备温度均控制在所要求的温度范围内,表明热控设计是合理和可行的。
According to Jade Rabbit Rover geometry,mission requirements and mission environment,the idea of thermal control system design for Jade Rabbit Rover is put forward; the thermal control system designs for Jade Rabbit Rover during moon day and moon night are described,in which a two-phase fluid loop and a radioisotope heat unit are used to warm Jade Rabbit Rover in moon night. Thermal control system for Jade Rabbit Rover is tested by using the thermal balance tests and flight tests,and the temperature of the equipment meet technical criterion.
