Thermal Design and Parameter Optimization of Optical Controlled Phased Array Radar

In order to ensure the stable operation of microwave transmitting front end component in optical controlled phased array radar and provide a reasonable temperature environment for high heat flux power amplifier,the thermal design scheme according to the structure of integrated system and the input parameters was proposed and analyzed by simulation.The results show that the maximum system temperature and temperature uniformity meet the requirements.The design scheme verifies that the efficient heat dissipation can be achieved by using the efficient diamond/copper heat expansion and reasonable liquid cooled cold plate.Moreover,the structure optimization schemes of multi stage fins and auxiliary fins with relatively insertion were proposed,and influence parameters of heat dissipation were analyzed.The optimization schemes provide ideas for thermal design of high heat flux components in radar.
