| Abstract: | Using the lumped parameter method based on unsteady-state heat transfer,this paper established that the temperature drop of heat sink in thermal vacuum environment simulator system was exponentially dependent on the time though the analysis of the heat transfer differential equation.And also gives the function of the principle of temperature of test sample and the time of temperature drop though the calculations of radiation heat transfer when heat sink temperatures stable.This paper also analyzed the inter... |
