Abstract:
1. A heat pipe, comprising: a heat receiving section; a heat transfer section; a heat dissipation section coupled to the heat receiving section through the heat transfer section, the heat transfer section is disposed between the heat receiving section and the heat dissipation section; and a groove structure formed in an inner wall of the heat pipe and extending from the heat receiving section through the heat transfer section to the heat dissipation section, provided with at least an axially-extending parallel portion and a non-axially-extending parallel portion; wherein the axially-extending parallel portion comprises a plurality of first groove segments extending parallel in an axial direction of the heat pipe and the non-axially-extending parallel portion comprises a plurality of second groove segments corresponding to, respectively connected to and extending from the first groove segments in a parallel manner in a direction different from the axial direction of the heat pipe, forming continuous grooves extending from one end to another end of the heat pipe, where the entire heat pipe is devoid from any intersecting groove segments, whereby the non axial-extending parallel position is subject to substantially uniform heating from the heat receiving section for increased heat transfer between the ends of the heat pipe.
