We present physical and dynamic thermal mathematical 
models in distributed and lumped parameters, calculation algorithms, 
software, and some results of numerical calculations of radiative-conductive 
heat exchange in blocks and modules carrying thermally loaded on-board 
equipment in a nonhermetic instrumental compartment of a proposed 
durable communication spacecraft with improved mass, size, and energy 
characteristics improved in comparison with traditional hermetic compartments.
