  • 摘要:

    深低温环路热管是一种高效的深低温两相传热器件,未来可广泛应用于红外探测等空间项目的低温热控系统。为有效减小热管与热负荷间的接触热阻及热管的背向漏热,采用氧化锆作为毛细芯材料,研发了氮工质平板蒸发器环路热管,重点研究了热管的自启动特性、传热性能以及在间歇性热负荷下的运行情况。结果表明:在无辅助情况下,液氮温区平板蒸发器环路热管自启动性能良好,可依靠工质扩散从室温迅速降温至液氮温区。环路热管能够在70~100 K温区稳定运行,热阻随运行温度和热负荷的上升而减小,最大传热功率为15 W,最小热阻为0.8 K/W。在蒸发器间歇性加热的情况下,环路热管可以保持温度稳定,热响应迅速,无需二次降温。液氮温区平板蒸发器环路热管有效满足了空间低温光学系统的热控制系统的热传输需求。
