Description
FIELD OF THE INVENTION
[0001] The present invention relates to a thermal conducting
device, in particular to a vapor chamber produced by a folding
method.
BACKGROUND OF THE INVENTION
[0002] In general, a vapor chamber is a hollow casing substantially
in a flat slab shape, and the casing are formed by engaging two
detachable folding boards, and a chamber is formed between the two
folding boards and provided for installing a capillary tissue, an
operating fluid and a support structure, etc. Since air must be
removed or vacuumed in the casing, therefore the two folding boards
must be soldered or thermally pressed after the two folding boards
are engaged with each other, so as to seal the periphery of the two
folding boards and facilitate the operation of removing air or
vacuuming the vapor chamber.
[0003] However, the larger the edge of the vapor chamber, the more
difficult is the manufacture of sealing the edge. As a result, the
problems of a high defective rate and inconvenience arise.
Particularly, the sealed edge may be cracked easily after the vapor
chamber has been used in an environment of being heated on one
surface of the vapor chamber and cooled on the other surface of the
vapor chamber for a while, and the operating fluid sealed in the
vapor chamber may be leaked, or the vapor chamber may fail to
exchange heat when air enters into the chamber, or totally break
down.
[0004] In view of the aforementioned shortcomings of the prior art,
the inventor of the present invention based on years of experience
in the related industry to conduct extensive researches and
experiments, and finally developed a folding vapor chamber in
accordance with the present invention to overcome the shortcomings
of the prior art.
SUMMARY OF THE INVENTION
[0005] Therefore, the present invention is to provide a vapor
chamber having a casing formed by folding a board, and at least one
side of the casing being formed by a folding edge, such that the
length of a sealing edge of the vapor chamber can be reduced to
achieve the effects of lowering the defective rate of the
manufacture, completing the edge sealing operation quickly, and
preventing the sealing edge from being cracked to extend the using
life of the vapor chamber.
[0006] Accordingly, the present invention discloses a folding vapor
chamber comprising a plurality of folding boards covered and
coupled with one another, a folding edge formed between the
adjacent folding boards and provided for connecting folding boards
integrally, and the adjacent folding boards being bent and covered
onto one another by the corresponding folding edge, and a capillary
tissue installed on an internal surface between the folding
boards.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] The technical characteristics and contents of the present
invention will become apparent with the following detailed
description accompanied with related drawings. The drawings are
provided for the purpose of illustrating the present invention
only, but not intended for limiting the scope of the invention.
[0014] With reference to FIGS. 1 and 2 for schematic views of an
unfolded vapor chamber and an operation of folding the vapor
chamber in accordance with the present invention respectively, the
present invention provides a folding vapor chamber, comprising a
casing 1 having at least two folding boards 10, 11 engaged and
covered onto one another, and a folding edge 12 formed between the
adjacent folding boards 10, 11 for connecting the folding boards
10, 11 integrally, wherein the adjacent folding boards 10, 11 are
bent and covered onto one another by the corresponding folding edge
12 (as shown in FIG. 3), such that a hollow space is defined
between the engaged folding boards 10, 11 (as shown in FIG. 4).
[0015] In the aforementioned preferred embodiment of the present
invention, the casing 1 is comprised of two opposite folding boards
10, 11, and the areas of the two folding boards 10, 11 are
substantially equal, and the folding edge 12 is formed between the
two folding boards 10, 11. In FIG. 1, the capillary tissue 2 and
the support structure 3 are installed on an internal surface of the
casing 1, before the casing 1 is formed by engaging the two folding
boards 10, 11 and folding the two folding boards 10, 11 at the
folding edge 12, such that the capillary tissue 2 and the support
structure 3 are disposed between the two folding boards 10, 11 (as
shown in FIG. 4) after the two folding boards 10, 11 are folded at
the folding edge 12. In addition, the capillary tissue 2 can be
comprised of grooves, meshes or sintered powders and installed
separately on the internal surface of the two folding boards 10,
11.
[0016] In FIGS. 2 and 3, a sealing edge 100, 110 is reserved at the
periphery of each of the two folding boards 10, 11, such that after
the two folding boards 10, 11 are folded, the sealing edges 100,
110 are overlapped for facilitating the edge sealing operation. In
FIG. 4, after the two folding boards 10, 11 are folded at the
folding edge 12, the sealing edges 100, 110 of the two folding
boards 10, 11 are overlapped. After the two folding boards 10, 11
are folded, at least one side is sealed by the folding edge 12, so
that the length formed by the folding edge 12 for performing the
edge sealing operation can be reduced to achieve the effects of
expediting the edge sealing operation, lowering the defective rate,
and preventing the sealing edge from being cracked easily.
[0017] In FIGS. 2 and 3, an air removing tube 13 is formed at the
sealing edges 100, 110 of the folding boards 10, 11 for
facilitating the air removing operation at a later stage, and the
casing 1 can be formed integrally. The air removing tube 13 can be
formed at the sealing edge 100, 110 of any one of the folding
boards 10, 11, or opposite half-tube portions 130, 131 can be
formed at the sealing edges 100, 110 of the two folding boards 10,
11 respectively in accordance with the preferred embodiment of the
present invention, such that after the two folding boards 10, 11
are folded at the folding edge 12, the two half-tube portions 130,
131 are stacked to form the air removing tube 13.
[0018] In FIGS. 5 and 6, the casing 1 is comprised of three folding
boards 10, 11, 14, wherein one folding boards 10 has an area
substantially equal to the sum of areas of the other two folding
boards 11, 14, and a folding edge 12 is formed between adjacent
folding boards 10, 11, 14 for connecting the three folding boards
10, 11, 14 integrally and provided for the other two folding boards
11, 14 to be folded and engaged onto the folding board 10 with a
larger area by the corresponding folding edge 12.
[0019] With the aforementioned assembly, the folding vapor chamber
of the present invention can be achieved.
[0020] In the folding vapor chamber of the present invention, the
casing 1 of the vapor chamber is made by bending and folding a
board. Compared with the conventional vapor chamber produced by two
detachable folding boards, the present invention can reduce the
sealing edge formed by the folding edge 12 and thus can lower the
defective rate of the edge sealing operation and preventing the
vapor chamber from being cracked at the sealing edge easily.
[0021] In summation of the description above, the present invention
improves over the prior art and complies with the patent
application requirements, and thus is duly filed for patent
application.
[0022] While the invention has been described by means of specific
embodiments, numerous modifications and variations could be made
thereto by those skilled in the art without departing from the
scope and spirit of the invention set forth in the claims.
