Abstract

This dissertation discusses the simulation and experimental research concerning an integrated infrared detector supporting structure. We verified this structure's heat-transfer characteristics and thermal stress by setting test benches and a vacuum-water cooling system. We tested the temperature on both ends of the supporting structure. The conclusion drawn from comparing the calculated value with the test result is, this integrated infrared detector supporting structure can transmit the cooling capacity from the cold head to the infrared detector with coupling temperature difference in 2K; x-y-z slot for releasing stress can effectively reduce the thermal deformation caused by thermal stress, meeting the demand of infrared detector imaging.
