环路热管 (LHP) 是一种多功能两相传热装置，在太空和陆地应用中越来越被接受。 LHP 的工作温度是其工作条件的函数。对于给定的热负载和散热器温度，LHP 通常会达到稳定的工作温度。当热负载和/或散热器温度变化时，工作温度也会变化，但在大多数情况下最终会达到另一个稳定状态。然而，在某些条件下，环路工作温度永远不会真正达到真正的稳定状态，而是变得振荡。本文利用微型 LHP 的测试数据讨论了温度振荡现象。
Loop heat pipes (LHPs) are versatile two-phase heat transfer devices that have gained increasing acceptance for space and terrestrial applications. The operating temperature of an LHP is a function of its operating conditions. The LHP usually reaches a steady operating temperature for a given heat load and sink temperature. The operating temperature will change when the heat load and/or the sink temperature changes, but eventually reaches another steady state in most cases. Under certain conditions, however, the loop operating temperature never really reaches a true steady state, but instead becomes oscillatory. This paper discusses the temperature oscillation phenomenon using test data from a miniature LHP.
