Abstract
Modern active phased antenna arrays (APAA) have a high packing density of receiving and transmitting modules (RTMs), the number of which can reach several thousand elements, depending on the tasks being solved. When the entire system is operating, the efficiency of the RTM is about 20–30%. As a result of the high packing density of the APAA elements, a large amount of heat is released, which must be dissipated. Due to low efficiency, traditional air cooling is used only in long-wave systems. Most modern active phased array antennas are cooled by liquid, as well as by organizing heat removal with the use of heat pipes. The article presents a method of thermal protection that allows to increase the reliability of the RTM. The results of thermal protection functioning are included.
