Abstract
The thermal fields of the “Photon-Amur 2.0” payload electronic board developed for nanosatellites were studied. The “Photon-Amur 2.0” payload consists of an electronic control board with a casing mounted in a nanosatellite and a remote panel with experimental photovoltaic converters. A modified heat balance method was used for numerical simulation of the thermal fields of the control board and the casing. The constructed model and the obtained results of the numerical simulation were verified by comparison with the thermal diagrams obtained for the “Photon-Amur 2.0” electronic board under normal operating conditions. For modeling the outer space operating conditions, it was assumed that there is a vacuum outside and inside the “Photon-Amur 2.0” casing, and the thermal effect is transmitted from the nanosatellite racks to the payload electronic board through the fastenings. The thermal effect is of a periodic nature with amplitude of –45 to +80○C and a period of 96 min, which approximately corresponds to the motion of a nanosatellite in a 575 km-high orbit. It was demonstrated that with such composition of the payload module, its casing can work as a passive thermoregulator of thermal fields on the electronic board of “Photon-Amur 2.0”. The simulation showed that the casing helps to keep the temperature on the control board in the interval of –15°C to +85°C, which is acceptable for the electronic components used on the payload control board.
