Flat heat pipe structure

Abstract

A flat heat pipe structure includes a flat pipe, a radial capillary structure and an axial capillary structure. The pipe has a containing space for sealing and storing a working fluid, and the pipe is formed by two opposite bottom walls and two sidewalls laterally and respectively disposed on the two bottom walls, and the pipe further has an evaporation portion, and the radial capillary structure is situated in the evaporation portion and radially surrounded and attached onto the two bottom walls and two sidewalls, and the axial capillary structure is extended in a lengthwise direction of the pipe, disposed in the containing space, and attached onto one of the sidewalls, and the axial capillary structure is extended to the evaporation portion of the pipe and coupled to the radial capillary structure.
