Radar Structure with Multi-cavity Coupling Sealed Cooling Ducts

This paper discusses a radar structure with multi-cavity coupling sealed cooling ducts. These ducts can achieve independent cooling with various power dissipation systems, thus improving the working ability of the complete machine at high temperatures. The seal structure increases the ability of the radar to operate under harsh circumstances and guarantees its round-the-clock working mode. The thorny problem of heat dissipation of the radar components, such as the TR module, wave-controlled power supply board, signal processing and microwave module, is solved. The adaptability of the complete machine to high-low temperature, dampness and hotness, salt mist, sand and dust, EMC, etc. is also improved.
