Development of a thermal mathematical model for the simulation of transient behavior of a spaceborne equipment in vacuum environment

This paper focuses on the development of a thermal mathematical model representing a spaceborne electronic equipment in thermal vacuum test environment. the model was based on thermal network method (tnm). simulations with the model were carried out using a commercial thermal analysis software package. the predictions obtained with the model were compared with the thermal vacuum cycling test measurements. transient standard deviations between the predictions and the test measurements show that the mathematical model developed was able to represent the thermal vacuum environment accurately and it can be utilized in the design phases of similar spaceborne equipment. © 2015 tibtd printed in turkey.
