摘要：

This study proposes effective thermal management solutions for vehicle-mounted active electronically scanned array (AESA) radar systems via the improvement of existing cooling systems and optimization of heat dissipation for T/R and SAM modules. Unlike previous studies that focused on coolant flow optimization, which often requires costly system modifications, this research suggests practical solutions that involve additional heat dissipation structures or optimized shapes for existing aluminum housings. The results of a numerical analysis shows that the application of these solutions reduces the maximum temperature of component C in the T/R module from 52.1 degrees C to 27.5 degrees C and 35.9 degrees C. The temperature deviation was also significantly reduced from 23 degrees C to 0.4 degrees C and 1.5 degrees C, thus improving cooling performance and reducing temperature variation by up to 85%.
