Abstract: Flat heat pipe is widely used in the field of high heat flux electronic devices due to its advantages of large heat transfer area, high performance and strong geometric adaptability. With the development of high performance, integration and miniaturization of electronic devices, the flat heat pipe tends to be ultra-thin, and the grooved wick structure with stable structure, light weight and small size becomes the preferred solution to solve the problem of heat dissipation of flat heat pipe in limited space. The traditional groove processing technology has high cost and limited groove processing size. Etching technology has the advantages of high processing efficiency and wide range of processing structure size, which has gradually become the main processing method of flat heat pipe groove wick structure. The types and applications of flat heat pipe and the characteristics of different etching technologies are introduced in detail. The research progress on the fabrication of groove wick structure of flat heat pipe by etching technology at home and abroad are summarized. Furthermore, the shortcomings that existed on the etching process of groove wick structure are pointed out and it is also suggested that more efforts should be made to what in the future.

Key words: etching processing, flat heat pipe, groove wick structure, microstructure manufacture
