Study on the Cooling System of the Electronic Equipment in the Cabin of the Stratospheric Airship

Abstract

Nowadays, the strategic value of the stratospheric airship attracts more and more attention of the countries. Based on the analysis of the working performance of the stratospheric airship, a cooling system of the electronic equipment is designed and its performance throughout the flight altitude is investigated. The results show that the single cooling system based on cold plate cannot fulfill the cooling task in the extreme hot day and a parallel cooling system as a bench should be designed .meanwhile, the temperature of the cold plate is gradually decreased and then gradually rose with the altitude. The lowest temperature in the process is-35.95°C which would has effect on the performance of the cold plate. Therefore , electrical heating system and frequency regulating speed ventilator are proposed in the above cooling system which is responsible for the electronic equipment at the optimum temperature .
