平流层电子设备温度特征的仿真与试验研究
Numerical simulation and experiment for thermal behavior of stratospheric electronic equipment
摘要
Abstract
A theoretical model is established to investigate the thermal characteristics of stratospheric electronic equipment,considering the stratosphere environment such as temperature,pressure,wind velocity,earth and solar radiation, as well as the structure, materials and power of the electronic equipment. The influences of solar radiation, wind velocity, power and other parameters on the temperature of electronic equipment are analyzed. An experiment is conducted and discussed to prove the reliability of the mathematical model. The results show that:forced convection and radiation can affect the temperature of the stratospheric electronic equipment, and the convection heat dissipation is the main factor. The convection heat dissipation accounts for 87.9%,when the wind velocity is 15 m/s and the convection heat dissipation accounts for 58.5% when the wind velocity is 3 m/s. The two factors should be taken into consideration in the process of thermal design.关键词
