Azarenkov V. Analytical solution of the heat equation in problems of analysis and synthesis temperature fields of electronic equipment

Object of research: steady-state and transient thermal processes in electronic equipment of various designs providing both passive and active ways of heat rejection. Goal of research: improvement of existing thermal process models and creating new thermal process models of electronic equipment, development of methods to analyze electronic equipment temperature fields and structural synthesis in order to enhance reliability, efficiency as well as to decrease time of developing new products. Methods of research: heat exchange theory methods, equation dimensionality decomposition/ variable separation methods, field superposition method, Wegstein method of successive approximation. Theoretical and practical results: the development of scientific and methodological framework for the analysis of temperature regimes and synthesis of design parameters when solving design problems electronic equipment. Scientific novelty: development of analytical methods to solve tasks of transient heat conduction, i.e. methods aimed at designing and analysis of a thermal state of various design electronic equipment. The implementation: work results have been introduced at the following enterprises: Russian Research and Design Institute of Automated Control Systems of GazProm (Kharkov), "PRIBOR" Production Enterprise, (Kursk, Russia), "PROTON" Central Design Bureau, State Enterprise (Kharkov), "TRANSMASH" Scientific Production Center (Lugansk) and "HIDROPRIVOD" (Kharkov). Application area: theoretical and methodological bases for designing-and-engineering of hardware components, electronic equipment and other complex technical objects, industrial engineering equipment.
