Abstract. The problem of increasing the heat sink of terminal equipment of voice communication control systems for air traffic controllers is being solved. Noise standards established for the workplace of an air traffic controller, together with reliability requirements, do not allow the use of active cooling for cooling of the terminals. A method of thermal calculation of terminal housings with passive cooling has been developed. The calculation of the heat-stressed state of the communication terminal housing has been performed. On the basis of finite element modeling, design changes are predicted that can significantly reduce the temperature of the terminal processor, thus extending the equipment service life. The adequacy of the obtained results was verified using experimental design and a full-scale experiment based on a full-scale specimen of the terminal.
