Thermal Design of an Airborne Radar Box and Its Simulation-based Optimization

In this paper,according to the working environment of a small airborne radar,the method of adding radiators on radar box is proposed.It is shown that,the relative movement between radiator and air gives rise to forced convection in flight which can solve the cooling problem of radar box.Then,the simulation is conducted with the software of FLOTHERM,not only to the thermal analysis of the radar box,but also to the optimization design of the radiator.
