Abstract

A supporting structure for vapor chamber includes a first and a second plate member, a supporting member, and a working fluid. The first and the second plate member together define a chamber between them. The supporting member is located in the chamber, and has at least one base portion and a plurality of supporting portions, such that a plurality of passages is formed on the supporting member. The working fluid is filled in the chamber to flow through the passages. With these arrangements, the supporting structure for vapor chamber can overcome the problems of deformation caused by thermal expansion or pressure and uncontrollable bottom flatness as found in the prior art and can be manufactured at reduced labor and time cost while provides upgraded heat transfer efficiency.

First claim

What is claimed is:

1. A heat pipe with a support structure comprising:
a first plate member having a first side and an opposite second side; a second plate member having a third side and an opposite fourth side; and being assembled to the first plate member to thereby define a chamber for a working fluid between the second side of the first plate member and the third side of the second plate member; and
a supporting member being located in the chamber, said supporting member comprising a sheet of material formed to define at least two regions, one of said regions defining substantially punctiform supporting portions disposed in a two dimensional array and being structurally interconnected to each other to define passages therebetween for working fluid;
another of said at least two regions disposed adjacent said one region defining substantially linear supporting portions extending in parallel and defining therebetween linearly extending passages for working fluid, said substantially linear supporting portions being connected at one end to said array of punctiform supporting members.

2. The heat pipe with a vapor chamber supporting structure as claimed in claim 1 , wherein the second side of the first plate member has a recess formed thereon; and the supporting member being disposed in the recess with the supporting portions thereof extending towards the second side.

3. The heat pipe with a vapor chamber supporting structure as claimed in claim 2 , further comprising a first wick structure provided between the supporting portions and the first plate member; the first wick structure being disposed in the recess to locate between the first plate member and the supporting member with one side of the first wick structure attached to the second side of the first plate member and another opposite side attached to the supporting portions.

4. The heat pipe with a vapor chamber supporting structure as claimed in claim 3 , wherein the supporting member comprises a base portion, said base portion being attached to the third side of the second plate member.

5. The heat pipe with a vapor chamber supporting structure as claimed in claim 3 , further comprising a second wick structure provided between the supporting member and the second plate member; and the second wick structure having one side attached to the third side of the second plate member and another opposite side attached to the base portion.

6. The heat pipe with a vapor chamber substantially punctiform supporting structure as claimed in claim 1 , wherein the supporting portions have a configuration selected from the group consisting of a square, a rectangle, a trapezoid, a circle, an elongate strip, and any other geometric shape.

7. The heat pipe with a vapor chamber substantially punctiform supporting structure as claimed in claim 1 , wherein the supporting portions are arranged in arrays, such that the passages are perpendicular to one another.

8. The heat pipe with a vapor chamber supporting structure as claimed in claim 1 , wherein the first and the second plate member are respectively made of a metal sheet.

9. The heat pipe with a vapor chamber supporting structure as claimed in claim 6 , wherein the first and the second plate member are respectively made of a material selected from the group consisting of a copper sheet, an aluminum sheet, a copper foil-covered graphite sheet, and any other sheet material with good heat conductivity.

10. The heat pipe with a vapor chamber supporting structure as claimed in claim 1 , further comprising a working fluid filled in the chamber to flow through the passages.
