Aiming at the change of temperature field caused by parabolic nang-pit structure parameters,thermal analysis and parameter optimization of nang-pit structure were carried out.Firstly,a parametric geometric general model was established by Solidworks,and the design method of the parabolic nang-pit was studied.Secondly,the thermal analysis of the nang-pit structure was carried out using ANSYS,and the cloud map of the temperature field distribution was obtained,which verified the accuracy of the finite element model.Finally,the design parameters of the transition arc and the heating source were optimized,and the optimized temperature distribution was obtained.The results show that the parabolic nang-pit has better constant temperature characteristics,and increasing the height of the heating source can effectively improve the temperature field of the nang-pit,which provides an analytical basis for the research on energy conservation and environmental protection of the nang-pit.
