Modelling results on characteristics of the cooling system, which combines the Peltier element with the radiator-emitter, are presented in the paper. Despite wide application of Peltier elements, characteristics of this system are hardly studied since there are no such combinations under the terrestrial conditions. The necessity to study the parameters of this combined cooler arose because such systems are planned to be used for thermal stabilization of detectors in the promising space telescope ART-XC, used at the Russian-German observatory “Spectrum-RG” and in monitor SPIN-Х1-ASM, which will be installed at the International Space Station (ISS). According to modelling, the cooler consisting of the Peltier element and radiator-emitter has some unusual properties caused by the complex feedback between these units.
