Research on Air Cooling of a Radar Planar Array Antenna

Air cooling has many advantages such as simple equipment, low cost, high reliability and good safety. Nowadays, with the rapid development of modern electronic technology, air cooling continues to be one of the priority options in radar cooling design. This article focuses on the cooling requirements of the active array antenna of a phased array radar and optimizes its heat dissipation structure using thermal simulation software. Through a comprehensive matching design of air flow distribution technologies such as air distribution unit, static pressure box and air supply orifice plate, the precise air flow distribution for large planar array antenna under the condition of centralized air source is achieved. Highly integrated air cooling design of the system is realized, which expands the technical path of radar air cooling. It can provide reference for similar system design.
