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.
