In addition, along with the demand sustainable growth of communication, commercial satellite, particularly military satellite, and the development tendency that satellite miniaturization, maximization and common platform are applied, the heating power of device on star is constantly increased; The capacity weight of common platform rolls up and also makes the thermal energy consumption density of whole star increasing, and its heat removal issue is also more and more serious.Only rely on the body heat delivery surface of satellite cannot meet the thermal control requirement of model.For addressing this problem, external satellite has had the experience of application expandable type exciter.As HS702 platform, Laura SS/L1300 platform, the Laura SS/L1300E satellite platform of the U.S., the larger communication satellite platform Alphabus etc. in Europe.
The structure of exciter itself will produce working medium flow resistance problems.Existing exciter, especially large radiation device, when working medium pipeline is long, will cause internal system pipeline flow resistance too large.If external drive is LHP system, flow resistance may cause too greatly LHP to run unsuccessfully; If the fluid loop system of driven by mechanical pump, exciter flow resistance too senior general causes mechanical pump wasted work to increase; And in order to solve the problem, when working medium circuit design shorter is reduced inner flow resistance, exciter isothermal will be caused again poor, exciter radiating efficiency is reduced.
Therefore, no matter be as expandable type exciter or heat dissipation cabin plate, especially when radiator area is larger, while guarantee isothermal, flow resistance problems of too must be solved.
