Abstract:

The Processor is the core electronic equipment of aerobat high rate communication terminal, the stability and reliability of the processor are directly related to the reliability of the whole terminal system equipment. The characteristics and methods of thermal design of high-rate terminal processor are introduced, according to different power devices and components, combined with structural design, a reasonable way of heat dissipation is explored. In particular, the thermal design of many power devices with high heat consumption. Optimizing thermal design scheme through thermal simulation analysis, control the temperature rise of each device to meet the design requirements, thermal vacuum and thermal balance tests were carried out to verify the results.
