The invention discloses a micro spacecraft single-phase fluid loop autonomous thermal control heat dissipation device, and particularly relates to the field of liquid cooling heat dissipation, the micro spacecraft single-phase fluid loop autonomous thermal control heat dissipation device comprises a spaceflight mounting plate, a single-phase loop liquid cooling pipe and a circulating pump, the single-phase loop liquid cooling pipe is welded on the top of the spaceflight mounting plate, and the circulating pump is arranged on the outer wall of the single-phase loop liquid cooling pipe; the inner wall of the single-phase loop liquid cooling pipe is fixedly connected with a supporting piece, the inner wall of the supporting piece is connected with a transmission rotating column through a bearing, one end of the transmission rotating column is fixedly connected with a rotating fan blade, the rotating fan blade is obliquely arranged, and the outer wall of the transmission rotating column is fixedly connected with a special-shaped gear. By arranging the special-shaped gear and the corresponding piston plate, when refrigerant fluid flows, the rotating fan blades can drive the special-shaped gear to rotate, and finally the piston cylinder continuously pressurizes the interior of the single-phase loop liquid cooling pipe through the air inlet pipe; the problems that the pressure of the single-phase loop liquid cooling pipe is too small due to the too low temperature in the space, refrigerating fluid cannot flow, and the refrigerating efficiency is reduced are solved.

    本发明公开了微小航天器单相流体回路自主热控散热装置,具体涉及液冷散热领域,包括航天安装板、单相回路液冷管和循环泵,单相回路液冷管焊接在航天安装板的顶部,循环泵设在单相回路液冷管的外壁,单相回路液冷管的内壁固定连接有支撑件,支撑件的内壁通过轴承连接有传动转柱,传动转柱的一端固定连接有旋转扇叶,旋转扇叶呈倾斜状设置,传动转柱的外壁固定连接有异形齿轮。本发明通过设置了异形齿轮和对应型活塞板,当制冷液进行流动时,旋转扇叶就会带动异形齿轮进行转动,最终使活塞筒通过进气管不断的对单相回路液冷管内增压,解决了太空中温度过低导致单相回路液冷管压力过小制冷液无法流动制冷效率降低的问题。
