The invention provides an optical load two-dimensional pointing mirror thermal control device and a two-dimensional pointing mirror. The optical load two-dimensional pointing mirror thermal control device comprises a film type heater, thermal control white paint and extinction black paint. The two-dimensional pointing mirror is formed by connecting a pointing mirror with a Y-direction motor and an X-direction motor; thin film type heaters are arranged on the X-direction motor, the Y-direction motor, the pointing mirror and the U-shaped frame. Thermal control white paint is sprayed on the surface of the X-direction motor, and extinction black paint is sprayed on the surface of the Y-direction motor, the surface of the U-shaped frame and the back face of the pointing mirror. The temperature of the motor, the frame, the pointing mirror and other components is independently controlled, the heat dissipation capacity and the temperature compensation capacity are achieved, the on-orbit complex heat flow change condition can be adapted, and the application requirements of different rails are met.

    本发明提供了一种光学载荷的二维指向镜热控装置及二维指向镜,包括:薄膜型加热器、热控白漆以及消光黑漆;二维指向镜由指向镜连接Y向电机和X向电机构成;所述X向电机、所述Y向电机、所述指向镜以及U型框架上布局薄膜型加热器;所述X向电机表面喷涂热控白漆,所述Y向电机表面、所述U型框架表面以及所述指向镜背面喷涂消光黑漆。本发明中的电机、框架、指向镜等各部件独立控温,即具有散热能力也具有温度补偿能力,能够适应在轨复杂的热流变化条件,满足不同的轨道的应用需求。
