This paper discusses the problem of heat transfer in service based on unsteady heat transfer theory. Firstly, the unsteady partial differential heat transfer equations are established according to the law of conservation of energy, and the initial values and boundary conditions are determined. Two unknown convective heat transfer coefficients are involved in the heat transfer model of the work suit. The optimal heat transfer coefficient is determined by describing the numerical relationship and solving the optimization problem, which can be applied to the thickness design of the work suit. The relationship between the convective heat transfer coefficient and the measured temperature is established by the least square method. Furthermore, the unsteady heat transfer model is solved numerically by explicit difference method, and the stability and accuracy of the model are verified. Finally, according to the solution results, the temperature distribution and parameter fitting effect of the work suit are shown, which proves the effectiveness and reliability of the model in practical application.
