Integrated thermal control device for small satellite and space optical camera

Abstract

The integrated thermal control device for small satellites and space optical cameras involves the field of aerospace, and solves the problem that small satellites provide small active thermal control power consumption for space optical cameras and cannot keep the working temperature of space optical cameras within the required range, which leads to problems in space optics. The problem of camera reliability and image quality degradation. It includes a plurality of cross-flexible connectors fixed on the sun-facing surface of the space optical camera, the cross-flexible connector adopts a cross-section structure with reed gaps crossed; a plurality of heat insulation pads placed one-to-one on the cross-flexible connectors; The camera solar cell array fixed together with the thermal insulation pad and the cross flexible connector, the camera solar cell array is connected with the small satellite through the cable; Multi-layer insulation components. The operating temperature of the space optical camera is kept within the required range, the active thermal power consumption is increased, and the reliability and imaging quality are improved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an integrated thermal control device for a small satellite and a space optical camera. Background technique [0002] The satellite operates in a space environment. Since the temperature in the space environment can reach below minus 100°C, and the operating temperature of the space optical camera 5 is 20°C, such a temperature difference will cause the structural frame and optical mirrors of the space optical camera 5 to deform and Failure of electronic components and the like lead to a decrease in or even complete loss of the imaging capability of the space optical camera 5 . In order to ensure that the space optical camera 5 works at a normal temperature, thermal control design for the space optical camera 5 is required. At present, the thermal control of the space optical camera 5 adopts a thermal control implementation method combining passive thermal control and active th...
