Design and development of self-circulating evaporative cooling system for 1600W transmitter

This paper introduces a self-circulating evaporative cooling system for TV broadcast transmitters. Through practical testing, it was shown that the evaporative cooling technology can be used to cool the high power density electronic equipment. This system not only breaks the thermal bottleneck of air cooling, but also has the advantages of a better cooling effect, low noise output, a simple structure and high reliability. The system thus shows great potential in its cooling capability.
