| Abstract: | Using thermal control heat sink in thermalvacuum test involves a number of merits, such as goodeconomical efficiency, easiness in use, no barrier to testspecimens, and finds more and more applications in test. Tocalculate the system capacity accurately in the equipmentdesign, a simulation scheme is proposed in this paper, basedon a distributed parameter model and expressed in state-space.The simulation scheme can be applied to test and comparedwith different control schemes. It can be used in the initialdesign stage or in thermal vacuum test. |
