The pulsating heat pipe(PHP), as a high effective heat exchanger device for the strength, which is expected to be applied to the field of heat transfer enhancement of energy and chemical equipment with its unique advantages. Firstly, in this works, the effects of heat pipe structure and working fluid on the heat transfer enhancement of pulsating heat pipes(PHP) are reviewed. Secondly, the recent research progress of PHP management theory and numerical simulation is summarized. Finally, some essential problems were exhibited which provided reference and direction for the future research of PHP technology.
