Abstract

The invention relates to a sandwich precision thermal controller for a spatial optical remote sensor reflector, belongs to the technical field of thermal control of spatial optical remote sensors and solves the technical problems that the prior reflector mirror is unevenly heated and has ordinary stability and temperatures of the reflector mirror and a support structure are non-uniform. The sandwich precision thermal controller comprises an inner temperature control device, an outer temperature control device and a reflector support structure; the inner temperature control device and the outer temperature control device are identical in structure; the reflector support structure is disposed between the inner temperature control device and the outer temperature control device; a reflector is disposed in the inner temperature control device; the reflector support structure is disposed between the inner temperature control device and the outer temperature control device. The temperature of the reflector is controlled through controlling the temperature of an inner radiator, the temperature of the support structure is controlled through controlling the temperature of an outer radiator, and temperature uniformity is effectively ensured for the reflector and the support structure.

Description

technical field [0001] The invention belongs to the technical field of thermal control of space optical remote sensors, and in particular relates to a sandwich type precision thermal control device used for reflectors of space optical remote sensors. Background technique [0002] With the development of space observation technology and the continuous improvement of the performance of space optical remote sensors, the requirements for temperature control of space optical remote sensor reflectors are also getting higher and higher, because the temperature stability of space optical remote sensor reflectors and their supporting structures and Temperature uniformity is the main factor affecting imaging quality. The thermal control method of the reflector of the traditional space optical remote sensor is to install a heater on the reflector and its supporting structure components, feed back the temperature through the temperature sensor pasted on the reflector and its supporting ...
