In this paper, the simulation of low temperature protective clothing with phase change material is taken as the research object, and the model based on heat conduction equation is established through Fourie heat transfer law, various heat transfer modes and three kinds of boundary conditions. Based on the principle of heat transfer, two kinds of heat transfer modes, heat conduction and heat convection, are mainly considered in this paper. First of all, through the analysis of the heat transfer mechanism of low temperature protective composites in low temperature environment, the boundary conditions of thermal insulation layer and fabric layer are the third kind of boundary conditions, which can be regarded as a convective heat transfer process. Then the partial differential extraordinary model can be established according to the boundary conditions. The interior of the thermal insulation layer, the functional layer and the fabric layer are heat conduction, which can be solved by establishing a model according to Fourier law. Then this paper simulates the above two models and uses the implicit post-difference scheme (Crank method) to solve them in parts.
