| description | The development trends of modern electronic equipment included in radar stations consist of a constant increase in the
output radiated power. This leads to a significant increase in heat generation of power amplification units as the most
heat-loaded ones. To reduce failures of these units associated with overheating, this work proposes an original algorithm
for quickly maintaining the temperature regime. The algorithm is based on a thermal model, which allows, unlike the
known ones, to calculate the temperature distribution in the block in real time, taking into account telemetry from
temperature sensors installed inside the block. The novelty of the proposed algorithm lies in the real-time control of the
cooling system based on the block temperature forecast obtained using a thermal model. The thermal model is based
on the mathematical formalization of thermal processes using the anisotropic body method, which allows minimizing
the computational costs of calculations by representing the power amplification unit as a quasi-homogeneous body.
Simulation of the temperature distribution process in the power amplification unit was performed in the COMSOL.
To evaluate the efficiency of the algorithm and the ability to operate in real time at the operational stage of the radar
station, a computational experiment was performed using model data. The simulation results confirmed the possibility
of calculating the temperature distribution in the block in real time. Unlike existing algorithms for maintaining the
temperature regime of a block, based on the readings of temperature sensors that determine the temperature at the current
moment in time, the developed algorithm implements a temperature forecast. This allows you to take measures to cool
the unit before the onset of critical emergency situations. |
