Abstract

Pulsating heat pipe(PHP) has many advantages, such as small volume, simple structure, low cost, good heat transfer performance, it have great potential in the application of refrigeration, aerospace, waste heat recovery and low - grade energy utilization. Based on the analysis of a large number of research results at home and abroad, the application status of pulsating heat pipe technology is summarized in this paper, which can provide scientific guidance for the design, operation and large-scale application of pulsating heat pipe.

Highlights

With the development of modern high-tech, the heat load per unit area of many thermal equipment is getting higher and higher, such as ultra-high power integrated circuits, high-temperature fuel cells for power generation, nuclear reactors, it is often necessary to miniaturize the cooling or heat exchange equipment
Because the pulsating heat pipe has the advantages of small volume, high flexibility, simple and compact structure, low cost and high heat transfer performance, the research and development of the low-temperature waste heat recovery device for pulsating heat pipe was carried out, it will play a positive role in promoting in the field of further energy-saving work
Xu [8] designed a new type of solar collector with pulsating heat pipe, the results showed that the efficiency of the system was greatly affected by the heat transfer performance of the pulsating heat pipe, and the heat resistance decreased with the increase of temperature

Introduction

With the development of modern high-tech, the heat load per unit area of many thermal equipment is getting higher and higher, such as ultra-high power integrated circuits, high-temperature fuel cells for power generation, nuclear reactors, it is often necessary to miniaturize the cooling or heat exchange equipment. As a new type of heat transfer device, pulsating heat pipe has great potential applications in thermal control technology and other cooling fields, with small size, high flexibility, low cost, high heat transfer performance. The application research status of pulsating heat pipe in low temperature waste heat recovery, solar energy utilization, electronic components cooling and other fields is summarized, which can provide scientific guidance for the design, operation and largescale application of pulsating heat pipe. Xiahou Guo-wei [3] proposed a parallel grooved plate pulsating heat pipe with radial connection and studied its start-up and heat transfer for the air energy recovery. In the year of 2010, Fumin Shang [4, 5] designed an exciting coupled pulsating heat pipe heat exchanger, as shown in figure 1, the coupling pulsating heat pipe was composed of the main pulsating heat pipe and the Cooscillation pulsating heat pipe, which point-to-point (or face-to-face) contacted and the orthogonal distribution of the two tube bundles of the pulsating heat pipe, an optimal effect of enhanced heat transfer could been obtained by the two mutual incentive pulsating heat pipes
