Abstract: This paper introduced the structure and working principle of Oscillating Heat Pipes (OHPs) and reviewed recent experimental and theoretical studies that involving visualization，thermal characteristics，theoretical/analytical models as well as the progress in nanofluid OHPs and micro OHPs. The applications of OHPs available in diverse areas were summarized. Key factors influencing the development of OHPs，such as model prediction，design optimization and heat transfer limit，were discussed.

Key words: oscillating heat pipe, visualization, thermal characteristics, modeling, application
