Micro heat pipe （MHP） is widely used to cool equipments of aerospace electronics, avionics, military electronics, automotive technologies, computers and so on. It is one of main approaches which can cool electronic components of high heat-fluxes effectively. At present, it becomes one of hotspots of modern heat pipe technology. Most of the studies are focused on the principle of heat and mass transfer and vapor-liquid flow in the MHP, novel design of high effective MHP structure,improvement of MHP manufacture technology and so on. In this paper, recent studies on MHP are summarized as four parts： theoretical analysis and experimental study of the MHP principle, design of new structure MHP, manufacture technology, application of MHP, and the development trend.
