Heat pipe structure
A heat pipe structure includes a pipe body, a thin-sheet member, and a plurality of bosses. The pipe body internally defines a receiving space, in which a working fluid is provided. The thin-sheet member includes a plurality of first extended sections and a plurality of second extended sections. The first and the second extended sections are connected to and intersected with one another to thereby define a plurality of intersections and open spaces on the thin-sheet member. The bosses are provided on at least some of the intersections of the first and the second extended sections to provide supporting strength for the heat pipe structure as well as vapor-liquid circulation of the working fluid in the heat pipe structure.
1. A heat pipe structure, comprising:
a pipe body internally defining a receiving space and having a first closed end and a second closed end connected to two opposite ends of the receiving space, and having a working fluid provided in the receiving space;
a thin-sheet member being arranged in the receiving space of the pipe body and including a plurality of first extended sections and a plurality of second extended sections, the first and the second extended sections being connected to and intersected with one another to thereby together define a plurality of intersections and open spaces on the thin-sheet member; and
a plurality of bosses including a plurality of first and second bosses, wherein the first and second bosses are respectively located on opposite surfaces of the thin sheet member such that each first boss is positioned directly opposite to a corresponding second boss.
2. The heat pipe structure as claimed in claim 1 , wherein the first extended sections are extended in a longitudinal direction of the thin-sheet member.
3. The heat pipe structure as claimed in claim 1 , wherein the second extended sections are extended in a transverse direction of the thin-sheet member.
4. The heat pipe structure as claimed in claim 1 , wherein the pipe body is a flat pipe body.
5. The heat pipe structure as claimed in claim 1 , wherein the bosses are copper bosses and are provided on respective outer surface with at least one groove.
6. The heat pipe structure as claimed in claim 1 , wherein the bosses are sintered powder bodies and are provided on respective outer surface with at least one groove.
7. The heat pipe structure as claimed in claim 1 , wherein the bosses are sintered powder bodies.
8. The heat pipe structure as claimed in claim 1 , wherein the bosses are copper bosses and are provided on respective outer surface with a ring-shaped sintered powder body.
9. The heat pipe structure as claimed in claim 1 , wherein the first extended sections respectively have a curved shape, and each of the curved first extended sections defines a passage at a concaved side thereof.
