Abstract
Based on the non-Fourier heat conduction wave model, the thermal wave scattering near the opening in the platinum–rhodium glass fiber leaky plate structure is studied by using complex function method and conformal mapping method, and the general solution of the thermal wave scattering problem is given. The boundary condition of the open surface is adiabatic. The influence of the geometrical and physical parameters of the leaky plate on the temperature distribution in the plate is analyzed, and the numerical results of the temperature concentration are given. This study can provide theoretical basis and reference data for the design and optimization of the opening structure of platinum–rhodium glass fiber leaky plate.

Summary
Platinum–rhodium alloy material has high temperature resistance, corrosion resistance and oxidation resistance, which is used to process glass fiber in engineering manufacturing. The entropy of the system depends on the properties of equilibrium states such as temperature, and on some other parameters such as the heat flux This is one of the basic understandings of the extended thermodynamics. The thermal wave model such as the CV model is compatible with the basic principles of the second law of thermodynamics The essence of this question is that the CV model is mistakenly put under the conceptual framework of the equilibrium continuum model. The problem of thermal wave scattering and surface temperature distribution in a Pt–Rh GFLP structure based on the wave equation of non-Fourier heat conduction is studied, and the effects of various physical parameters on temperature distribution is analyzed. The analysis in this paper is of great significance for solving the problem of concentrated temperature distribution near openings or defects in various metal plates at extremely high temperatures
