The active electronically scanned array (AESA) radar consists of many transmit/receive (T/R) modules and is used to track missiles approaching destroyers fighters. performance the AESA depends on T/R module temperature. temperature should be maintained under 80 °C guarantee radar. In order match design requirements cooling system radar, it necessary evaluate according various operation/installation environments. this study, computational fluid analysis was performed by changing number coolant mass flow rate channel. changed from 2 16, inlet Re 277 11,116. As a result, confirmed that increased as increased. addition, when status laminar flow, significantly lowered. Therefore, transient or turbulence decrease module. Additionally, correlation between arrangement must considered cool
