Stratospheric airship electronic equipment cabin temperature control system and control method

Abstract

The invention discloses a stratospheric airship electronic equipment cabin temperature control system and control method. The control system include a phase-change heat storage subsystem, a liquid circulation subsystem and a blower cooling subsystem; the phase-change heat storage subsystem includes a phase-change heat exchanger and a heat pipe installed on the phase-change heat exchanger; the liquid circulation subsystem includes a heat exchanger, a pump and a liquid storage device which are arranged in an electronic equipment cabin; the heat exchanger, the pump, the liquid storage device and the phase-change heat exchanger are connected with one another sequentially through a first pipeline so as to realize circulation; the heat exchanger is connected with high-heat flux density electronic equipment; the blower cooling subsystem includes a blower and a blowing-in pipeline; the blower is communicated with a second pipeline and a third pipeline respectively; the phase-change heat exchanger is located in the second pipeline; and the third pipeline is communicated with the blowing-in pipeline. With the stratospheric airship electronic equipment cabin temperature control system and control method of the invention adopted, adverse effects which are caused by a situation in which a single cold source cannot meet refrigerating requirements in low-altitude flight of an airship in an extreme hot weather can be prevented, and insufficient refrigeration in the high-altitude height of the airship in low atmospheric density can be also prevented.

Description

technical field [0001] The invention relates to a temperature control system for an electronic equipment cabin, in particular to a temperature control system and a control method for an electronic equipment cabin of a stratospheric airship. Background technique [0002] With the rapid development of aerospace technology and the continuous evolution of the concept of information warfare, the strategic value of the stratospheric airship has attracted the attention of more and more countries. Compared with other aerospace vehicles, the stratospheric airship has the advantages of low cost, long fixed-point stay time, fast response, and large coverage area. Recently, due to the unique advantages of stratospheric airships in the fields of communication, surveillance, and defense, it has developed rapidly in military and civilian applications. [0003] However, a key issue in the design of a stratospheric airship is the thermal control of the cabin equipment. The operating altitu...
