摘　　要：空间太阳能热动力发电系统是一种新型的空间电力系统。吸热器是热动力发电系统关键部件之一。吸热器腔体的热辐射将直接影响到吸热腔的热损失和吸热器的传热。建立了太阳能热动力发电系统吸热器腔体辐射模型 ,结合换热管的传热模型计算了吸热器的传热过程。得到了吸热器热损失 ,换热管最大温度 ,工质出口温度等结果 ,并进行了比较、分析。Solar Dynamic Power System should be the future space energy system.The heat receiver is a key part of SDPS.The heat loss and heat transfer is effected significantly by the heat radiation in heat receiver cavity.The heat radiation mathematical model of heat receiver cavity is established and is used to calculate the heat transfer of heat receiver.The heat model of exchange tube is also used to calculate the heat transfer of heat receiver.Heat loss,maximum temperature and gas exit temperature are calculated.The results was analysed and could be used in heat receiver designing.
