Thermo-siphon type heat pipe manufacturing procedure and structure

The invention provides a thermo-siphon type heat pipe manufacturing procedure and structure. The manufacturing procedure includes the steps that a section of metal material is adopted, the metal material is integrally formed to form a column pipe, the column pipe is provided with a planar bottom face, a diversion face in a preset shape is arranged on the inner wall of the column tube, a heat exchange face is arranged on the inner face of the bottom face of the column pipe, tube contracting forming is conducted on the top of the column pipe, the inner portion of the column pipe is pumped to be in an approximate state and filled with a high speed heat conduction liquid medium, and welding and packaging are conducted on a contracted pipe on the top of the column pipe. In this way, the integral forming is adopted for the manufacturing process of a thermo-siphon type heat pipe, the bottom of the thermo-siphon type heat pipe makes contact with a heat source, additional machining is not needed, the bottom face, name
