液氮温区低温回路热管的实验研究——第一部分:结构设计和实验系统

EXPERIMENTAL STUDY OF A CRYOGENIC LOOP HEAT PIPE USING NITROGEN AS WORKING FLUID Part1:CONFIGURATION DESIGN AND EXPERIMENTAL SYSTEM

由于回路热管是近20年内发展起来的新技术,因而除理论研究外在实验研究方面仍需要进一步深入研究。此外,为改善制冷机与被冷却器件的集成关系,需要发展能够工作在深低温区的低温回路热管。为此,搭建了低温回路热管的实验台,并设计了一种结构简单的低温回路热管,为下一步研究低温回路热管的启动特性和传热特性做准备。

A cryogenic loop heat pipe(CLHP) using nitrogen as working fluid is developed for future aerospace application.CLHP is a kind of heat pipe that can operate at liquid-nitrogen temperature range and lower cryogenic temperature range.Without moving parts and complicated control,CLHP can provide effective thermal link and vibration isolation between cryogenic cooling sources and cryogenic components.A design of cryogenic LHP configuration and corresponding test system are presented.
