Analysis Of Heat Transfer Performance Of Thermal Suit Based On Fourier Law

In this paper, we use the Fourier law of heat conduction, combined with the convection theory and the heat radiation theory, to establish a three-dimensional temperature field model, and analyze the influence of the temperature of each layer of the thermal protective clothing with the change of time and space position under the unsteady condition. After the derivation of the Fourier heat transfer formula, we compare the temperature field to the electric field and derive the unified formula of the temperature field. In addition, we optimize the thickness of each layer according to the actual situation.
