Formulation of the problem. Modeling of thermal modes, which is an obligatory part of the design of electronic devices, requires a thermal model of the structure − a simplified representation that adequately reflects the heat transfer processes under study. Such a model should be simple enough for a mathematical description and provide the possibility of using typical software tools for its analysis. Which explains the relevance of the topic under consideration.

Purpose. Increasing the efficiency of solving the problems of analysis and ensuring the thermal regime in the design of radioelectronic means.

Results. A method for constructing a universal thermal model applicable to electronic devices of various design types. Such a model is formed by combining a limited number of unified design-thermal components, which makes it possible to simplify the required software, in particular, to obtain mathematical models of temperature fields in analytical form.

Practical significance. The use of the proposed approach makes it possible to simplify the process of building thermal models of radio electronic devices, reduce the simulation time, and effectively use widespread software systems (Creo, SolidWorks, etc.).
