Abstract
Solid State Power Amplifier (SSPAs) excessive thermal dissipation with high failure rate are becoming challenging tasks in the operation of satellite earth stations. Traditionally, forced-air cooled method has been the most well-known method adopted in removing excessive heat from high power SSPAs, but has not really prove so effective to bring down the heat to barest minimum. In this paper, we present the use of a liquid-cooled by developing a robust control system and heat exchanger module using temperature sensor, micro controller and water as coolant. Our design aims to optimize and increase the efficiency of the power amplifiers output and prevent failure or damage. The liquid-cooled thermal control module was built, assembled and tested within and outside the 35°C to 85°C operating temperature ranges of a typical SSPA. The result obtained shown that at the preset temperature of 35°C and below, the fan and pump were in the OFF state. At temperatures above 35°C, the fan and pump went into ON state simultaneously. In the event of fan or pump failure, (i.e. temperature above 85°C), the SSPA will automatically shuts down, the alarm will turn ON and the liquid crystal display (LCD) displayed fault. As the trend towards higher power dissipation and more concentrated heat sources continue in power amplifiers, a more effective solution is to use liquid cooled thermal control module to efficiently reduce heat dissipation in solid state power amplifier. It can be deduced from the overall results that aggressive heat dissipation removal in SSPAs is possible with liquid-cooled thermal control module.
