With the rapid development of infrared detector,the size of Dewar assembly becomes bigger,which needs the Dewar with lower heat consumption. The influence factors of Dewar heat consumption were analyzed theoretically,and these factors were verified through the experiments. The results show Dewar heat consumption is related to the emissivity of window surface and the thickness of cold finger,which provides a reference for the design,development and manufacture of Dewar.
