Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a capillary tissue,
especially to a heat pipe structure having a capillary tissue
formed with end part for supporting.
[0003] 2. Description of Related Art
[0004] 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.
[0005] 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.
[0006] 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
[0007] 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.
[0008] 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.

DETAILED DESCRIPTION OF THE INVENTION
[0013] Preferred embodiments of the present invention will be
described with reference to the drawings.
[0014] Please refer to FIG. 1 and FIG. 2, wherein FIG. 1 is a
perspective exploded view according to a first embodiment of the
present invention; and FIG. 2 is a perspective view showing the
assembly according to the first embodiment of the present
invention. The present invention provides a heat pipe structure
having a capillary tissue formed with end part for supporting,
which includes a pipe body 1 and a capillary tissue 2 installed in
the pipe body 1.
[0015] The pipe body 1 is formed as an elongated hollow tubular
body, a cross section thereof is formed in a round or flat status,
according to this embodiment provided by the present invention, the
flat status formed through being processed with a flattening
treatment is adopted for illustration thereby being able to be
installed in a ultra-thin heat pipe (having a thickness smaller
than 0.6 mm). As shown in FIG. 1, before the pipe body 1 is sealed,
the pipe body 1 is formed with a pipe member 10 and an end part 11
sealing one end of the pipe member 10, and the interior of the pipe
member 10 is formed with a 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'.
[0016] 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 disposed in the
above-mentioned pipe body 1. As shown in FIG. 3, the capillary
tissue 2 includes a primary capillary part 20 formed in a
strip-like status and a positioning capillary part 21 connected to
one end of the primary capillary part 20; the primary capillary
part 20 is allowed to pass the vapor flow channel 100 and abutted
against a lateral wall 101 formed in the pipe body 1, and the
positioning capillary part 21 is disposed at the end part 11 of the
pipe body 1 and formed with an arc-like connecting segment 210, and
an abutting segment 211 and a distal segment 212 in sequence
extended from the connecting segment 210, the connecting segment
210 allows the positioning capillary part 21 to be connected to one
end of the primary capillary part 20 so as to be extended, thereby
enabling the positioning capillary part 21 to be extended from the
lateral wall 101 to another lateral wall 101' of the pipe body 1,
the abutting segment 211 is abutted against the another lateral
wall 101', and the abutting segment 211 is bent along the length
direction of the pipe body 1 thereby allowing the distal segment
212 to be extended, so the distal segment 212 is able to be
extended to a proper length towards the vapor flow channel 100, and
two sides of the distal segment 212 are both formed with a space
allowing the vapor flow channel 100 to be kept; according to this
embodiment, the end part 11 of the pipe body 1 is formed with as an
inner conical surface 110, so the arc-like connecting segment 210
of the positioning capillary part 21 is able to be abutted against
the inner conical surface 110 of the end part 11 for providing an
enhanced positioning effect.
[0017] Accordingly, with the above-mentioned structure, the heat
pipe structure having the capillary tissue formed with end part for
supporting is assembled.
[0018] Please refer to FIG. 3, because the capillary tissue 2
includes the above-mentioned positioning capillary part 21 capable
of being abutted against the two lateral walls 101, 101' of the
pipe body 1, the capillary tissue 2 is enabled to be positioned and
also to provide a supporting effect in the pipe body 1, meanwhile
the extended distal segment 212 is able to prolong the transferring
path of the capillary tissue 2 and also able to enlarge the area
for supporting the end part 11 of the pipe body 1 or even able to
be extended along the length direction of the pipe body 1, thereby
providing a supporting effect to the full length of the pipe body
1.
[0019] Please refer to FIG. 4, which discloses a second embodiment
of the present invention; the other end of the primary capillary
part 20 of the capillary tissue 2 can also be formed with another
positioning capillary part 21', the another positioning capillary
part 21' is also formed with an arc-like connecting segment 210',
and an abutting segment 211' and a distal segment 212' in sequence
extended from the connecting segment 210', thereby being able to
provide a supporting effect to the another end part 11' of the pipe
body 1.
[0020] According to the heat pipe structure having the capillary
tissue formed with end part for supporting provided by the present
invention, after the capillary tissue 2 is disposed in the pipe
body 1, the positioning capillary part 21 is enabled to apply a
force to the two lateral walls 101, 101' formed in the pipe body 1
for being abutted against the two lateral walls 101, 101', thereby
being able to provide a positioning and supporting effect, and the
capillary tissue 2 formed with a desired shape can be sintered or
fastened in the pipe body 1, thereby preventing problems such as
being bent or the desired shape being deformed after being disposed
in the pipe body 1. When being applied in an ultra-thin heat pipe,
because the internal space of the heat pipe has already been
thinned, other positioning member or positioning mold is hard to be
disposed therein for assist the capillary tissue 2 to be
positioned, so the capillary tissue 2 is required to be provided
with a self positioning and supporting function after being
disposed in the pipe body 1 thereby being able to be applied in the
ultra-thin heat pipe. In addition, the above-mentioned distal
segments 212, 212' are not abutted against the lateral walls 101,
101' of the pipe body 1, so the distal segments 212, 212' can be
served as a supporting structure in the pipe body 1, and the vapor
flow channel 100 passes two sides of the distal segments 212, 212'
thereby effectively enlarging the evaporation or condense surface,
allowing the thermal resistance to be smaller and having a better
heat transferring effect.
[0021] Although the present invention has been described with
reference to the foregoing preferred embodiment, it will be
understood that the invention is not limited to the details
thereof. Various equivalent variations and modifications can still
occur to those skilled in this art in view of the teachings of the
present invention. Thus, all such variations and equivalent
modifications are also embraced within the scope of the invention
as defined in the appended claims.
