Design and Optimization of Heat Dissipation Structure for Compact Spectrometer Based on Finite Element Method
摘要
Abstract
The heat dissipation capacity and stability of compact spectrometers have an extremely important impact on detec-tion performance and service life.Firstly,this article completes the design of heat dissipation structure based on the development of a compact spectrometer.The temperature field and heat flux distribution of the whole machine are obtained by ANSYS finite element thermal analysis method.Then,based on the characteristics of temperature distribution and heat flux,an optimization scheme is pro-posed.Next,the optimization scheme is simulated from the aspects of heat dissipation performance,thermal deformation,and vibra-tion response.Finally,the analysis results are validated through experiments.The analysis and experimental results show that,the maximum temperature of the shell decreased from 44.4℃to 34.2℃,and the maximum temperature of the core device decreases from 39℃to 30℃.The comprehensive heat dissipation performance is improved by more than 20%.The thermal deformation is less than 0.05 mm,and the excitation frequency of the air-cooled power component is less than the natural frequency of the structure.The optimized heat dissipation structure is stable and reliable,and the heat dissipation effect is significantly improved.The instru-ment runs smoothly,and the optimized solution meets the thermal design requirements.The thermal design scheme of this compact spectrometer not only solves practical engineering problems,but also provides a certain reference for the thermal design and simula-tion of similar products in the future.关键词
