摘要
Abstract
With the rapid development of communication technologies,tiled phased array antenna has gradually become a new trend in the development of active phased array antenna because of its characteristics of miniaturization,high performance and high integration.However,with the continuous improvement of frequency band and integration,the heat flux of multifunctional integrated chip is increasing,and the resulting heat dissipation problem is more prominent.According to the thermal design requirements of a high frequency tiled phased array antenna,a low-cost cooling scheme of ″heat dissipation duct+flat heat pipe″ under forced air-cooling is proposed.The controllable temperature of the array heating device and the temperature consistency of the multifunctional integrated chip are verified by numerical simulation.A thermal testing platform is built to carry out the thermal testing,and the measured temperature at the testing point is contrasted with the simulated temperature.The numerical simulation and experimental results show that the designed thermal control structure can meet the requirements of the shell temperature of the heating device and the temperature consistency requirements of the multifunctional integrated chip,which further verifies the rationality of the heat dissipation scheme.To sum up,the proposed scheme can provide a certain reference for the subsequent thermal design of the similar tiled phased array antennas.关键词
