Research and development of loop heat pipe with flat evaporator

Loop heat pipe (LHP) is an efficient heat transfer device. Compared with other traditional heat pipes, the biggest advantage of LHP is its large heat transfer distance and anti-gravity operation. This study reviewed LHP, which is advantageous not only to the development of basic theory of LHP but also to the development and utilization of novel and high-efficiency LHP. In this review, the LHP are classified according to the shape of evaporator, and the progress of the experimental research and theoretical model research on the flat evaporator LHP in the past five years are introduced , including wick structure design, working fluid choice, evaporator optimization, evaporator model research and LHP system model research. In addition, the advantages and disadvantages of the six wick structures and their application status are analyzed, and the differences of several common working fluid and three conventional flat evaporator LHP system models are compared. Finally, the research status of flat evaporator LHP is summarized, and the scientific analysis and prospect of the experimental research and theoretical model research for the flat evaporator LHP are proposed.
