The research work in this paper focuses on a certain type of isolator which is widely used in some newly emerged inertial navigation system(INS).Under the help of thermodynamics finite element analysis(FEA),the heat-transfer performances of the isolator within both open and airtight working environment are obtained.Due to the unsatisfying result,a thermal conduction module(TCM)made by copper is designed.And the quantization result is accomplished accurately.The experiments and the proposed method have important sense in improving the heat-transfer condition and the system precision caused by the influence of temperature.
