摘　　要：自激振荡热管是一种可用于电子冷却的微通道传热元件,而无阀闭式环路型自激振荡热管(简称CLSOHP)由于具有特别的优势极可能用作电子散热装置。文章主要介绍了CLSOHP的工作原理,总结了影响其传热性能的因素,综述了目前在常壁温和常热流两种边界下已有的实验研究成果。通过对已有实验结果和装置的分析,提出了现有实验研究中的若干问题,为改进装置和提高实验结果的准确性提出了一些研究方向。Self-oscillating heat pipes are micro-channel heat-dispersing devices for electronics cooling, and it seems that close loop self-oscillating heat pipes（CLSOHP） without check valves can be used in electronics cooling for their special advantages. In this paper, the working principle of CLSOHP is described and the factors of affecting its thermal performance are summarized. The experimental results at the condition of constant temperature and constant heat input are reviewed. Some research directions are proposed for improving the device and enhancing the accuracy of experimental results.
