The main indicators of the quality of space vehicles (SV) are their reliability and lifetime (LT) in the orbit, and a significant role in this plays a temperature mode inside of SV, where are the devices. And one of their stable work is to create a specific thermal regime in the volume of construction, what is the thermal control system in which the heat mode is provided with fan provided by thermal relay at a given temperature. The main indicators of the quality of SV is their reliability and LT in orbit, and a significant role in this plays a temperature mode inside of SV, where are the devices. While circulating in the system of temperature control of heat-transfer fluid, for example, nitrogen, transmits heat from the cold surface of the satellite that radiate excess heat into space. At downturn of temperature of a working body under the specified fan is switched off, resulting who in the absence of convection - to a significant increase in thermal resistance between the radiation surface and internal displacement of the surface of the body, and, ultimately, prevented further decrease of the temperature. As a result of improving the control systems, along with the improvement of other life support systems in the LT satellites to date, is more than 10 years, and by 2016 planned LT up to 15 years.
