Application of Thermal Simulation on the Cooling of a Phased Array Antenna

Thermal design of antenna is an important part of radar structure design, and is key for antenna and radar system to work normally, safely, and reliably. At the same time, with the development of science and technology, thermal simulation is more and more important in electronic thermal design. This paper presented the thermal design of one phased arrays antenna. Firstly, several projects of heat dissipation was analyzed and compared. For the selected thermal project, CFD software FLUENT was used to simulate the cooling of the antenna and the simulation result provided useful data for the thermal design of antenna. Finally, by summarizing the analysis result, the writer raised his own point of view about the application of thermal simulations in complex system.
