The invention relates to the technical field of aerospace, in particular to a temperature control device of a space manipulator joint, which comprises a heating sheet, a heat dissipation surface, a temperature measurement sensor, a heat pipe, a graphite film and a heat insulation material, the heating piece and the heat dissipation face are arranged on the outer wall of an electric box shell of the space manipulator joint and the outer wall of a joint shell of the space manipulator joint except the side wall, where the joint female end of the space manipulator joint is located, of the joint shell. The temperature measuring sensor is arranged on the outer wall of the electric box shell; the heat pipes are installed on the outer walls of the two axial ends of the joint shell through screws. The graphite film is fixed on the inner wall of the joint shell through heat-conducting glue; the outer walls of the joint shell and the electric box shell are covered with the heat insulation material, and except for the heat dissipation face, the heating piece, the temperature measuring sensor and the heat pipe are all covered with the heat insulation material. The heat dissipation device is high in heat dissipation capacity and high in heat dissipation speed, and the problems that heat dissipation is difficult and temperature distribution uniformity is poor during continuous work of a space manipulator joint are solved.
本发明涉及航空航天技术领域,尤其涉及一种空间机械臂关节的控温装置,包括加热片、散热面、测温传感器、热管、石墨薄膜和隔热材料,其中,加热片和散热面均设置在空间机械臂关节的电箱外壳的外壁以及空间机械臂关节的关节外壳的外壁上,且除空间机械臂关节的关节母端所在的关节外壳的侧壁之外;测温传感器安装于电箱外壳的外壁上;热管通过螺钉安装在关节外壳的轴向两端的外壁上;石墨薄膜通过导热胶固定在关节外壳的内壁上;隔热材料包覆在关节外壳和电箱外壳的外壁上,且除散热面之外,并将加热片、测温传感器和热管全部包覆在其中。本发明散热能力强、散热速度快,解决了空间机械臂关节连续工作难以散热和温度分布均匀性差的问题。
