The invention discloses an inflatable expansion type flexible heat radiator for a spacecraft, and belongs to the technical field of spacecraft thermal control. The device comprises an inflatable frame, two flexible radiation films, a rigid-flexible combined pipeline or a full-flexible serial pipeline and a rigid connecting piece; the two flexible radiation films are stacked, a rigid-flexible combined pipeline or a full-flexible series pipeline is arranged between the two flexible radiation films, and the two flexible radiation films are bonded with the rigid-flexible combined pipeline or the full-flexible series pipeline through a heat-conducting adhesive. The rigid connecting piece is fixedly connected with one ends of the flexible radiation films and the rigid-flexible combined pipeline or the full-flexible series pipeline, and the inflatable frame is bonded with the edges, except the ends, of the two flexible radiation films. The heat radiator is made of a flexible composite material, is in a folded state before launching, is inflated and unfolded to form the large-area radiator after entering an orbit, and has the characteristics of light weight, high folding efficiency, small launching size, low launching cost, easiness in launching, high rigidity, large heat dissipation area, high heat dissipation power and the like.

    一种航天器用充气展开式柔性热辐射器,属于航天器热控技术领域。本发明包括充气框架、两片柔性辐射薄膜、刚柔组合管道或全柔性串联管道、以及刚性连接件;两片柔性辐射薄膜叠放设置,两片柔性辐射薄膜之间设置有刚柔组合管道或全柔性串联管道,两片柔性辐射薄膜通过导热胶粘剂与刚柔组合管道或全柔性串联管道粘接,刚性连接件与柔性辐射薄膜一端及刚柔组合管道或全柔性串联管道固定连接,所述充气框架与两片柔性辐射薄膜除所述一端以外的边缘粘接。本发明采用柔性复合材料制成,在发射前为折叠状态,入轨后充气展开成大面积辐射器,具有质量轻、折叠效率高、发射体积小、发射成本低、易于发射、刚度高、散热面积大、散热功率高等特点。
