N2 - The active electronically scanned phased array (AESA) radar mounted on a ship close-in weapons system (CIWS) includes hundreds of transmit/receive (T/R) modules including thousands of heating elements requiring a cooling design for the entire system. However, the numerical evaluation of the cooling system for the entire system requires a large computational cost owing to the large number of elements and differences in the size of each element. In this study, a simplified numerical evaluation of the cooling design for the entire system was conducted. The temperature of the heating element within the T/R module at each location was analyzed through the simplified step-by-step analysis method using the equivalent heat flux approach. Consequently, the mesh generation time was significantly accelerated by a factor of approximately 60, reducing computational costs while maintaining temperature discrepancies within 1% for individual components.
