Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The instant disclosure relates to a heat dissipating device;
in particular, to a heat dissipating device which is mountable on a
heat conducting pipe and works cooperatively therewith for heat
dissipation.
[0003] 2. Description of Related Art
[0004] Along with the enhanced living standard, people are becoming
more fastidious about their life quality. Particularly, to the
demands of better quality electronic devices and mechanical
products are increasing rapidly. Owing to the advanced electrical
appliances and technological products, people are leading a more
convenient lifestyle with significant changes to their working
efficiency. However, this has also brought about the issue of
researching a stronger power supply and products with higher
energy-conserving capabilities which are in desperate need of
resolutions. Generally, the use of electrical power often generates
lots of heat during normal operation. If not properly removed, such
heat can adversely affect the operational stability of the
electrical appliances, resulting in malfunction or damages to the
mechanical products. Therefore, most of the present electrical
appliances are equipped with heat dissipating devices to remove
heat therefrom.
[0005] Generally, the types of heat dissipating devices are many
having varying structural designs and providing identical or great
diversity of functional capabilities. And conventional heat
dissipating fins have at least one through hole defined therein,
where the heat dissipating fins are mounted on the heat conducting
pipes one piece after another. However, the repeating procedure of
mounting the heat dissipating fins may cause deformation to the
through holes. Thereby, resulting in unstable mounting of the heat
dissipating fins to the heat conducting pipes which further reduces
the heat dissipating efficiency.
[0006] To address the above issues, the inventor strives via
industrial experience and academic research to present the instant
disclosure, which can effectively improve the limitations described
above.
SUMMARY OF THE INVENTION
[0007] The object of the instant disclosure is to provide a heat
dissipating device where the structural design of the heat
dissipating fins of the heat dissipating device can avoid
deformation of the through holes when the heat dissipating fins are
mounted on the heat conducting pipes. Furthermore, the concurrent
mounting of the heat dissipating fins on the heat conducting pipes
can also reduce time consumption to further facilitate the mounting
procedure.
[0008] A heat dissipating device is provided to mount on at least
one heat conducting pipe which has a contacting portion that abuts
against a heat generating unit. And the surface of the contacting
portion in abutment with the heat generating unit is substantially
a flat surface. The heat dissipating device includes a heat
dissipating fin which has a main body, where at least one through
hole is defined on the main body. At least a set of ribs is
vertically formed on the main body in a trumpet-like structure
around the through hole, where a slot is defined between every two
adjacent ribs. The heat dissipating fin further has a stacking
portion defined by at least one rectangular via hole formed on the
base and at least one ridge formed adjacently to via hole. At least
one heat conducting pipe is inserted into the through hole of the
heat dissipating fin with the ribs gripping resiliently against the
pipe.
[0009] A heat dissipating device is further provided to mount on at
least one heat conducting pipe which has a contacting portion that
abuts against a heat generating unit. And the surface of the
contacting portion in abutment with the heat generating unit is
substantially a flat surface. The heat dissipating device includes
a plurality of stacked heat dissipating fins. Each of the heat
dissipating fins has a main body, where at least one through hole
is defined on the main body. At least a set of ribs is vertically
formed on the main body in a trumpet-like structure around the
through hole, where a slot is defined between every two adjacent
ribs. The heat dissipating fin further has a stacking portion
defined by at least one rectangular via hole formed on the main
body and at least one ridge formed adjacently to the via hole.
Notably, the heat dissipating fins are arranged in parallel to each
other and at least one heat conducting pipe is inserted into the
through holes of the heat dissipating fins with the ribs gripping
resiliently against the pipe. The stacking portion of each of the
heat dissipating fins abuts against the stacking portion of the
adjacent heat dissipating fin.
[0010] Based on the above, the instant disclosure has the following
advantages:
[0011] The heat dissipating fins of the instant disclosure can be
attached to and stacked along the heat conducting pipes through a
single process which reduces a vast amount of time and cost spend
in the stacking procedure. The heat dissipating fins are also
prevented from bending or even deforming during the process. A
distance is kept between every two adjacent heat dissipating fins
during stacking to dissipate heat. The stacking portions of the
heat dissipating fins in the instant disclosure help to provide
structural stability for the heat dissipating fins when stacked and
reduce the material cost.
[0012] In order to further appreciate the characteristics and
technical contents of the instant disclosure, references are
hereunder made to the detailed descriptions and appended drawings
in connection with the instant disclosure. However, the appended

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The First Embodiment
[0020] Please refer to FIGS. 1-8. A heat dissipating device is
provided by the instant disclosure. For in use, the heat
dissipating device of the instant disclosure dissipates heat
produced from a heat generating unit 5, where the heat generating
unit 5 may be, but not limited to, a central processing unit (CPU)
or other electronic devices, etc. Furthermore, the heat dissipating
device is adaptable with three heat conducting pipes 3, where each
of the heat conducting pipes 3 has a contacting portion 31.
[0021] Referring to FIG. 1, the heat dissipating device includes a
plurality a heat dissipating fins 4 stacked on top of each other.
Each of the heat dissipating fins 4 has a sheet-like shape and a
main body 41, three through holes 42 formed on the main body 41,
three sets of ribs 43 vertically formed on the main body 41 each
forming a trumpet-like structure, a stacking portion 44 formed on
the main body 1, and a bent portion 45 formed on the main body 1.
For the instant embodiment, the number of through holes 42 on the
main body 41 is equal to the number of heat conducting pipes 3. In
other words, the quantity of each of these respective components is
three. An enlarged view to illustrate the structural features of
the heat dissipating fin 4 is shown in FIG. 2.
[0022] Please refer to FIGS. 3-4. The through holes 42 allow the
heat conducting pipes 3 to slide through the heat dissipating fins
4. And the ribs 43 are vertically formed on the main body 41 around
each through hole 42.
[0023] Each set of ribs 43 is defined by a plurality of slots 431.
Namely, every two adjacent ribs 43 are separated by the
corresponding slot 431 to increase the flexibility of each rib 43.
Thereby, each set of ribs 43 is capable of pressing elastically
against the respective heat conducting pipe 3. When the heat
dissipating fins 4 are fitted on the heat conducting pipes 3, the
flexible ribs 43 prevent the through holes 42 from deforming due to
repeated disassembly and reassembly. Each of the heat dissipating
fins 4 are enabled to grip tightly against the heat conducting
pipes 3 to increase the heat dissipating efficiency.
[0024] For the instant embodiment, the stacking portion 44 is
defined by six rectangular via holes 441 and six ribs 442 formed
respectively in an adjacent manner on the main body 41. However,
the structural design of the stacking portion 44 is not restricted
thereto. For the instant embodiment, two via holes 441 are formed
around each through hole 42 oppositely, and the ribs 442 are formed
bendingly adjacent to respective via holes 441 in a vertically
protruding manner on the main body 41.
[0025] Thereby, the ribs 442 of the stacking portion 44 of each of
the heat dissipating fins 4 abut against the ribs 442 of the
adjacent heat dissipating fins 4. Thus, a spacing is formed between
any two adjacent heat dissipating fins 4.
[0026] The bent portion 45 is defined by four tabs 451 arranged on
the periphery of the main body 41. For the instant embodiment, four
tabs 451 for provided. The bent portion 45 is formed by bending the
protrusions (not shown) formed on the periphery of the main body 41
in a right angled manner. Thereby, the bent portion 45 of one of
the heat conducting fin 4 will abut against the bent portion 45 of
the adjacent heat conducting fin 4, where the physical nature of
the bent portion 45 is not restricted.
[0027] Please refer to FIGS. 5-7. The heat dissipating device may
further include a base 1 and a cover plate 2, where both components
can be made of metallic materials. The base 1 has a supporting
portion 11 and a fastening portion 12. The supporting portion 11 is
a plate-like structure having an opening 112 formed thereon, while
the fastening portion 12 is formed extendingly from the supporting
portion 11. Furthermore, the fastening portion 12 has, but not
limited to, four protrusions 121. Two ramps 111 are formed
oppositely on the supporting portion 11 adjacent to the opening
112. For the instant embodiment, there are two ramps 111. In
addition, the physical nature of the base 1 is not restricted.
[0028] The cover plate 2 is a plate-like structure which
corresponds to the structural design of the base 1. The cover plate
2 has a restricting portion 21 defined by four restricting notches
211 concavely formed on the periphery of the cover plate 2. For the
instant embodiment, there are, but not limited to, four restricting
notches 211 available. The restricting notches 211 are engaged by
the protrusions 121 of the fastening portion 12 accordingly.
[0029] Please refer to FIG. 8. The contacting portions 31 of the
heat conducting pipes 3 are arranged in parallel within the opening
112 of the supporting portion 11. More specifically, the contacting
portions 31 abut against the sidewalls that define the opening 112
of the supporting portion 11. The surface of each contacting
portion 31 touching the heat generating unit 5 is substantially a
flat surface to achieve an enhanced heat dissipating effect.
Furthermore, the physical nature of the heat conducting pipes 3 is
not restricted.
The Second Embodiment
[0030] Please refer to FIG. 9 which shows a second embodiment of
the instant disclosure. For the instant embodiment, at least one
engaging member 46 is provided on each heat dissipating fin 4 in
replacing the bent portion 45 of the previous embodiment. More
specific descriptions will be provided hereinbelow.
[0031] The engaging member 46 includes an engaging body 461 and an
engaging slot 462. The engaging body 461 is formed by stamping and
kinking of the main body 41 to reduce the consumption of materials.
The engaging slot 462 is formed accordingly by the engaging body
461. The engaging body 461 of one heat dissipating fin 4 is engaged
to the engaging slot 462 of adjacent heat dissipating fin 4 to
maintain the stacked heat dissipating fins 4 in proper alignment
with each other. Furthermore, the structural design of the engaging
member 46 is not restricted.
[0032] Based on the above, a plurality of the heat dissipating fins
4 of the instant embodiment can be attached to and stacked along
the heat conducting pipes 3 concurrently. Therefore, the heat
dissipating fins 4 need not be mounted on the heat conducting pipes
3 one piece after another to reduce time consumption. Furthermore,
the base 1 and the cover plate 2 are connectively designed to
fasten the three heat conducting pipes 3 therebetween without the
utilization of glue and solder paste to reduce cost. The heat
conducting pipes 3, moreover, are disposed on the heat generating
unit 5 where the surface in contact therewith is substantially a
flat surface. Thereby, increasing the heat dissipating efficiency
of the heat dissipating device.
[0033] The descriptions illustrated supra set forth simply the
preferred embodiments of the instant disclosure; however, the
characteristics of the instant disclosure are by no means
restricted thereto. All changes, alternations, or modifications
conveniently considered by those skilled in the art are deemed to
be encompassed within the scope of the instant disclosure
delineated by the following claims.
