Review and Prospect of the Research Progress of Flat Micro-heat Pipe

Heat pipe is a kind of multi-scale heat transfer material with high thermal conductivity. It is widely used in the fields of heat recovery and reuse of heat exchanger, solar collector and data center cooling. The experimental study on the influence factors of micro heat pipe heat transfer was carried out from the aspects of cyclic power and performance. According to the structure composition and working mechanism of the flat micro-heat pipe, the research progress of flat micro heat pipe groove structure, filling working fluid, filling rate and working condition of the tube is reviewed. The relationship between the state of evaporating section and condensing section and the flow state and heat transfer characteristics is analyzed, such as curvature radius, flow rate and effective thermal conductivity. In this paper, the development of model structure design and theoretical prediction of flat micro-heat pipe is summarized, and the development trend of micro-channel of micro-heat tube is prospected.
