The temperature state of a plane dielectric layer at constant voltage and fixed temperature of one of the surfaces of this layer

Abstract

The paper formulates the nonlinear problem of steady‐state heat conduction at the constant electric potential difference on the surfaces of a plane dielectric layer with the temperature‐dependent heat conduction coefficient and electrical resistivity. A fixed temperature value is set on one of the layer surfaces, and the convective heat exchange with the ambient medium occurs on the opposite surface. The formulation of the problem is transformed to integral ratios, which allows the calculation of the temperature distribution over the layer thickness, governed by the monotonic and nonmonotonic functions. The quantitative assay of the temperature state of a layer of a polymer dielectric made of amorphous polycarbonate is given as an example and the analysis of nonuniformity of the absolute value of electric field intensity over the thickness of this layer.
