An obligatory component of the design process of modern radio electronic means is thermal design aimed at solving the issues of en-suring a normal thermal regime and performed at various stages of development.To optimize the construction of the cooling system, it is necessary to take into account all the features of heat transfer in the elements of the structure, the path of the passage of heat flows, the sources of waste water and what possible ways of heat exchange. In real designs of radio electronic means, many heat transfer paths are possible including parallel ones, transfer of heat fluxes: special heat sink devices, convection channels between modules and components, structural elements (frames, chassis, housings, electrical switching elements, air and insulating layers, etc It is advisable to use the structural-functional model of the cooling system in the form of a heat transfer graph G (X, U) in which the vertices Xi correspond to the elements of the construction, which are conditionally isothermal surfaces, and the edges ui are the heat exchange paths. If it is necessary to take into account several types of heat transfer, then the column introduces parallel edges. Such a model represents an opportunity to solve the problems of analysis and optimal distribution of heat fluxes within a particular design of a REM. As well as determining the maximum amount of thermal energy.
