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.
