- 2. Description of Related Art
- A conventional capillary tissue installed in a heat pipe is mostly formed through weaving fibers or metal wires or reeling a metal net, and after the weaving or reeling process is finished, a bending status oriented towards no specified direction is formed because of the residual stress provided by the material itself; when the above-mentioned capillary tissue is disposed in a pipe body of a heat pipe, a problem of difficult in disposing may be caused, or other problems such as not being able to be precisely positioned and formed in a desired status may also be caused.
- Take a strip-like capillary tissue (such as a capillary tissue having coaxially-arranged fibers) for example, the strip-like shape makes the capillary tissue hard to be kept in a linear status when being disposed in a heat pipe; the disposed capillary tissue can be sintered in the pipe body for being fastened with a sintering means, but if the capillary tissue is disposed in the pipe body before being sintered and there is no specified mold which can be used for shaping, or the residual stress provided by the material itself may cause deformation thereby losing the preset linear status, so the shape thereof formed through being sintered and positioned may not meet the anticipation; the capillary tissue can also be disposed through a means of being abutted against a lateral wall formed inside the pipe body, a problem of the pipe body recessing may be happened during a gas discharging operation, thus the original design of capillary tissue could not be kept, and the evaporation or condense surface could become smaller, the thermal resistance may be larger, and the heat transferring effect may not be as expected.
- Accordingly, the applicant of the present invention has devoted himself for researching and inventing a novel structure for improving the above-mentioned shortages.
- The present invention is to provide a heat pipe structure having a capillary tissue formed with end part for supporting, in which a hook-like capillary tissue is disposed in a heat pipe for positioning and supporting, so the capillary tissue is enabled to be effectively positioned in the heat pipe and capable of being served as a supporting structure thereby preventing a pipe body of the heat pipe from recessing.
- Accordingly, the present invention provides a heat pipe structure having a capillary tissue formed with end part for supporting, which includes a pipe body and a capillary tissue installed in the pipe body, the interior of the pipe body is formed with a vapor flow channel which is hollow and extended along the length direction thereof, the capillary tissue includes a strip-like primary capillary part and a positioning capillary part connected to one end of the primary capillary part, the primary capillary part is allowed to pass the vapor flow channel and abutted against a lateral wall formed in the pipe body, and the positioning capillary part is formed with an arc-like connecting segment and an abutting segment and a distal segment in sequence extended from the connecting segment; wherein, the connecting segment allows the positioning capillary part to be connected to one end of the primary capillary part thereby enabling the positioning capillary part to be extended from a lateral wall to another lateral wall of the pipe body so the abutting segment is enabled to be abutted against the another lateral wall, and the abutting segment is extended along the length direction of the pipe body thereby allowing the distal segment to be formed.
