Near space aerocraft and thermal control system thereof

Abstract

The invention discloses a near space aerocraft and a thermal control system thereof. The thermal control system of the near space aerocraft comprises a shrinkage capsule with expansion and shrinkage functions; the shrinkage capsule is arranged on the outer surface of a near space aerocraft shell; the surface, relative to a contact surface of the outer surface of the near space aerocraft shell, of the shrinkage capsule is also provided with a phase-change heat absorbing part used for absorbing radiant heat in a near space aerocraft cabin; the outside of the phase-change heat absorbing part is also provided with a first radiation coating; and the first radiation coating is used for absorbing the radiant heat in the near space aerocraft cabin and conducting the radiant heat to the phase-change heat absorbing part. The thermal control system disclosed by the invention is capable of keeping the temperature inside the near space aerocraft cabin relatively stable as well as simple in structure and thermal control way. The near space aerocraft disclosed by the invention is low in cost because of adopting passive thermal control and capable of effectively keeping the temperature inside the near space aerocraft cabin relatively stable so that equipment in the cabin can normally work.

Description

technical field [0001] The invention belongs to the technical field of near-space vehicles, and in particular relates to a thermal control system of a near-space vehicle and a near-space vehicle containing the thermal control system. Background technique [0002] Near space is a new space developed by the human economy, and near space vehicles will reside in this area for a long time in the future. Whether the equipment cabin of the aircraft can provide a relatively stable temperature environment determines the basic conditions for the normal operation of the equipment in the cabin. [0003] Because the ambient temperature in the airtight cabin of the aircraft is affected by the ambient temperature in the adjacent space, solar radiation, infrared radiation and solar reflection, and the heating of equipment in the cabin, the temperature may be too high during the day and too cold at night. In the external environment where the heat of electronic equipment is difficult to dis...
