In order to study the coupled thermal conductivity-radiation heat transfer characteristics of two-dimensional anisotropic materials, a computational method was developed for solving the coupled conduction-radiation heat transfer of two-dimensional anisotropic materials based on the basic idea of random walk for a uniform discrete mesh,and the accuracy of the computational method was verified. The effects of anisotropic thermal conductivity coefficient on the heat transfer characteristics were analyzed. The results show that for a two-dimensional plate, an anisotropic thermal conductivity coefficient results in a shift of the temperature field of the plate towards the corresponding anisotropy. The anisotropy of the plate is basically unchanged when the ratio of to is the same. The increase of leads to the change of the direction of the temperature conduction in the plate when the remains constant, which makes the temperature homogeneity decrease in the plate.
