开式节流制冷技术在局部环境温度控制中的应用研究

THE APPLICATION ANALYSIS OF THE OPEN J-T COOLING TECHNOLOGY IN THE TEMPERATURE CONTROL OF THE LOCAL ENVIRONMENT

摘要: 随着电子技术的飞速发展,电子设备集成度越来越高,功能越来越复杂,随之带来的热量耗散问题也越来越严重。对于飞行器设备舱内惯导等对环境温度极为敏感的精密机电一体化关键设备,环境温度将直接影响其工作精度。开式节流制冷效应能够有效的实现复杂热环境下惯导装置的短期环境温度控制。

Abstract: With the development of the electronic technology, the integration of the electronic equipment is high,the function of the electronic equipment is intricacy, so the cooling problem is graveness.The INS in the front equipment cabin of the missile is sensitivity in the temperature control of the environment, the J-T cooling technology is effective in the temperature control of the missile environment.
