Research progress on heat transfer enhancement and application of oscillating heat pipe

As a new type of heat pipe technology, oscillating heat pipe (OHP) has the advantages of simple structure, good heat transfer performance, and strong environmental adaptability. It has great application potential in heat transfer fields such as thermal management, solar heat collection, waste heat recovery, and etc. The rapid development of high heat flux devices, utilization and recovery of heat energy and other fields have put forward higher requirements for heat transfer performance and adaptability of heat transfer devices. In order to further enhance the internal two-phase flow heat transfer and adapt to different working conditions, new OHPs with various structures have been proposed. The research progress of the new structure OHP is mainly summarized from three aspects: the internal structure optimization to strengthen the thermal performance, the new external structure to meet the needs of different application requirements, and the application research of the new structure OHP. The follow-up research should design universal new structure OHPs on the basis of clarifying the operation mechanism.
