SPECIAL FEATURES OF THE THERMOPHYSICAL MODELING OF INSTRUMENT CUBICLES OF SPACECRAFT
G. V. Kuznetsov and S. F. Sandu UDC 629.783.084.7 Mathematical models which allow for the main mechanisms of heat transfer in instrument cubicles of modern spacecraft are presented. Results of numerical modeling of thermophysical processes in a typical module of the instrument cubicle of a communications spacecraft are given. On the basis of an analysis of multidimensional temperature fields we have drawn conclusions on the presence of substantial nonuniformity in the distribution of the temperature field in devices of radioelectronic spaceborne equipment.
