Results of developing the design of a modernized power cell for the imitation and filtering unit of a mobile radar. The reason for the modernization was the transition to a modern domestically produced element base, which required changing the electrical circuit diagram of the cell. As a result of the changes, it was possible to increase the output power of the power cell, which required changing the design of its cooling system. The main objectives of the study were to select the optimal design of the cooling system and develop a new design of the power cell taking into account the increased thermal loads. To solve these problems, modeling was used in the SolidWorks Flow Simulation program, which made it possible to determine the optimal parameters of the cooling system and the topology of the printed circuit board, ensuring stable operation of the device under new conditions. In addition to thermal analysis, during the design process, calculations were made of the mechanical stability of the cell to vibration and shock loads typical for the operating conditions of a mobile radar.

Modernization of the design of the cooling system of the power supply cell of the imitation and filtration unit of a mobile radar. The design of the cooling system of the power cell of the imitation and filtering unit of the mobile radar has been modernized. The proposed solution allows for effective cooling of the power cell, as well as its resistance to mechanical impacts.

The results of the work allow the introduction of a modernized power supply cell into the composition of mobile radar complexes, increasing their energy efficiency and reliability. The developed solutions can be used in the design of similar devices for other radio-electronic systems.
