Thermal management and design principles of stratospheric vehicles

Being aimed at the particular thermal-surroundings, this paper analyzed the complicated thermal features of stratospheric vehicles in the near space. In the measure of the thermo-control, two modes of the heat transfer which were radiation and convection were analyzed and compared based on the power consumption and thermo-control requirement of the load cabin. The result is that the convectional heat exchange efficiency is higher than the radiation and the system's weight of the convection is much lighter than the radiation in the same status. The more is that the seasonal changed and complicated spatial conditions have insignificant influence on the convection system what leads the convection system much more steady.
