Abstract
Pulsating heat pipe is regarded as a promising cooling technique for electronic devices. Investigations on thermal performance optimization for pulsating heat pipe will provide guide-line for the utilization of pulsating heat pipe. In this paper, thermal performance optimization for pulsating heat pipe via experimental investigations is introduced.Three optimization approaches are analyzed, including the improvement of structure, the utilization of working medium, and the treatment of internal surface. The mechanism of heat transfer enhancement of pulsating heat pipe is discussed, and the potential research field of thermal performance optimization for pulsating heat pipe is predicted. On the basis of familiarity with multiple pulsating heat pipe optimization strategy, it is necessary to explore coexistence mechanism of multiple optimizing strategy and develop pulsating heat pipe coupling enhanced heat transfer method.
