摘要
Abstract
Radioisotope thermoelectric generators(RTGs)are static energy conversion devices that di-rectly convert the decay heat of radioactive isotopes into electrical energy using thermoelectric mate-rials.They offer advantages such as a simple structure,stable and reliable operation,no moving parts,and light weight,leading to their wide application in deep space exploration and aerospace fields.A heat transfer model of an RTG was established,and a numerical simulation analysis of its in-ternal temperature field was conducted.The simulation results show good agreement with experimen-tal data,validating the accuracy and reliability of the developed simulation model.The temperatures of all internal components were found to be significantly lower than the material tolerance thresh-olds,satisfying the thermal safety requirements under actual operating conditions and effectively en-suring stable operation within a safe temperature range.The analysis results,combining the thermal expansion behavior of the heat source with the temperature field distribution characteristics,provide data support for optimizing the structural design of RTGs.关键词
