On the basis of studying the heat transfer characteristics of plastic windows,the finite difference method in two-dimensional heat conduction theory is used to establish the governing equations of heat transfer and the corresponding boundary conditions.The mathematical model of the whole window is established,and the mathematical model is numerically calculated through MATLAB programming to complete the calculation of the heat transfer coefficient of the whole window.The comparative analysis with engineering data illustrates the feasibility of the model.
