摘要
Abstract
For variable high power device for GEO communication satellite,three methods of thermal control are presented,including heat dissipation and compensation,heat dissipation and control,and heat storage and dissipation.Meanwhile,according to temperature index of the device,detailed theoretical calculation and simulation are carried out.The results show that the three methods can meet all the requirement of temperature of the device,and the deviation between theoretical and simulation results is less than 10 ％.In addition,by comparing the advantages and disadvantages of the three methods based on power and weight,the heat dissipation and control method is the ideal method because it can not only reduce the weight of system,but also not the consume of energy.In practical engineering applications,a reasonable method of variable high power device heat dissipation should be selected combing with the considering weight,power consumption,reliability,security,process and many other factors.关键词
