Description
FIELD OF THE INVENTION
[0001] The present invention relates to a capillary tissue,
especially to a heat pipe structure having a circuitous capillary
tissue.
DESCRIPTION OF RELATED ART
[0002] 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 elastic recovering force 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.
[0003] 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, and a forming
space is required to be reserved for allowing a vapor flow channel
to be formed, so the capillary tissue is often installed at single
side in the pipe body of the heat pipe thereby reducing the
vaporization area and lowering the heat transferring effect. If two
sides are respectively installed with a strip-like capillary
tissue, the two capillary tissues are spaced far away from each
other thereby being unable perform mutual transfer, and a returning
effect for a liquid-state working fluid is affected, also a problem
of recessing may be happened during a gas discharging
operation.
[0004] Accordingly, the applicant of the present invention has
devoted himself for researching and inventing a novel structure for
improving the above-mentioned shortages.
SUMMARY OF THE INVENTION
[0005] The present invention is to provide a heat pipe having a
circuitous capillary tissue, in which a linear capillary tissue is
circuitously arranged for being disposed in a heat pipe, so the
capillary tissue is easier to be positioned or formed in a desired
status, thereby enabling the capillary tissue to be effectively
positioned in the heat pipe and to be served as a supporting
structure for preventing the pipe body from recessing.
[0006] Accordingly, the present invention provides a heat pipe
having a circuitous capillary tissue, which includes a pipe body
and a capillary tissue installed in the pipe body; the pipe body is
formed with a pipe member and two end parts respectively sealing
two ends of the pipe member, and the interior of the pipe member is
formed with a vapor flow channel which is hollow and extended
towards the length direction thereof, and a working fluid is stored
therein; the capillary tissue is formed with a primary capillary
part, two secondary capillary parts and communicating capillary
parts which are all formed in a strip-like shape and pass the vapor
flow channel, the communicating capillary parts are connected
between the primary and the secondary capillary parts thereby
continuously forming a circuitous status; wherein, the two
secondary capillary parts are both extended along the length
direction of the pipe body and respectively abutted against two
lateral walls extended along the length direction of the pipe
member, and two sides of the primary capillary part are both formed
with a space allowing the vapor flow channel to be kept.

vapor flow channel 100 (as shown in FIG. 3) which is hollow and
extended along the length direction of the pipe body 1 and
communicated with the other end of the pipe member 10 which is
formed in an opened status, thereby allowing the capillary tissue 2
to be disposed in the vapor flow channel 100; when the capillary
tissue 2 is disposed in the pipe body 1 and the air inside the pipe
body 1 is discharged, the other end of the pipe member 10 is sealed
thereby forming another end part 11', and a sealing structure 12 is
formed at the end part 11'.
[0015] The capillary tissue 2 is formed as a strip-like member
through sintering powders, weaving fibers or metal wires or reeling
a metal net, and the capillary tissue 2 is installed in the
above-mentioned pipe body 1. As shown in FIG. 3 and FIG. 4, the
pipe member 10 of the pipe body 1 is further formed with a bottom
wall 101, a top wall 102, and two lateral walls 103 surrounding the
bottom wall 101 and the top wall 102, and the above-mentioned vapor
flow channel 100 is defined by the bottom wall 101, the top wall
102 and the two lateral walls 103. The capillary tissue 2 is formed

capillary part 20 are both formed with a space allowing the vapor
flow channel 100 to be kept; in addition, the two communicating
capillary parts 23, 24 are respectively formed in an arc-like
status or a linear status and respectively abutted against an inner
partial portion defined at one of the end parts 11, 11' of the pipe
body 1, thereby being able to be connected between the primary and
the secondary capillary parts 20, 21, 22, and the liquid-state
working fluid is allowed to be transferred between the primary and
the secondary capillary parts 20, 21, 22.
[0016] Accordingly, with the above-mentioned structure, the heat
pipe structure having the circuitous capillary tissue is
assembled.
[0017] Please refer to FIG. 4, the capillary tissue 2 is disposed
in the pipe body 1 with a circuitously-arranged manner, and the two
secondary capillary parts 21, 22 are abutted against the two
lateral walls 103 thereby being formed in a bending status so as be
easier to be positioned inside the pipe body 1, because of the
connecting effect provided by the communicating capillary part 22,
the primary and the secondary capillary parts 20, 21, 22 enable to
the liquid-state working fluid to be transferred therebetween,
meanwhile the vapor flow channel 100 can be kept at the spaces
formed at two sides of the primary capillary part 20, thereby

21, 22 can be respectively formed with an arc-like or linear
auxiliary capillary part 210, 220 extended from a free end thereof,
and the two auxiliary capillary parts 210, 220 are further extended
with an abutting segment 211, 221 towards the primary capillary
part 20 thereby being abutted against the primary capillary part
20. As such, the capillary tissue 2 in the circuitous status can be
further formed in a loop-like status for allowing the liquid-state
working fluid to be transferred in a relatively smoother fashion in
the capillary tissue 2.
