The article presents the results of thermal modeling of the data conversion unit of the data reception, transmission and processing device. In SolidWorks CAD, the models of the functional cells of the unit were developed, they were combined in the volume of the unit, and boundary conditions were formed to describe the processes of heat exchange with the air environment. Approaches and algorithms that improve the thermal mode of the unit were analyzed. These include iterative placement algorithms that allow step-by-step approach to the optimal option and genetic algorithms that implement a randomly directed search. Using the built-in Simulation module of SolidWorks CAD, a series of model experiments were conducted to study the thermal mode of the unit and a variant of the internal placement of functional cells was proposed that ensures the best temperature indicators without making significant changes to the design of the unit.

Conduct thermal modeling of the data conversion unit using the built-in tools of SolidWorks CAD and develop recommendations for improving the temperature indicators of the device.

During thermal modeling, it was possible to reduce the maximum temperature to Tmax=70.95 oSE, which is almost 6 oC (7.5%) less than the initial temperature of the block. The improvement of the temperature mode of the block operation was achieved by placing the most heat-generating functional cells in the extreme switching positions, as well as placing weakly heated cells near them. This made it possible to form an almost uniform temperature field inside the block and direct the heat flow from highly heated elements to the external environment. Practical significance. It is shown that at the early stages of designing a radio electronic device, it is possible to optimize the block design according to the thermal criterion and, in a finite number of iterations, obtain a solution that meets the established technical requirements.
