CCD temperature control system of satellite-borne hyperspectral detector

The invention discloses a CCD temperature control system of a satellite-borne hyperspectral detector.CCD heat is transferred to a heat sink, a graphite film heat conduction cable and a heat pipe, and is guided into a refrigeration system of an on-satellite radiation cold plate with a temperature control function. The system comprises two independent CCD temperature control mechanisms, and each temperature control mechanism comprises a CCD refrigeration package and a heat conduction transmission structure. Meanwhile, the two CCD temperature controllers share one on-satellite radiation temperature control structure. A passive refrigeration mode is mainly adopted, no mechanical moving part and no power refrigeration device are adopted, so that the size and complexity of the system are reduced, energy is saved, the reliability of the system is improved through a specially designed packaging structure, and the problems that a CCD device without a refrigeration package is complex in temperature control structure an
