Description
FIELD OF THE INVENTION
[0001] The present invention relates to a press fitting method for
heat pipe and heat sink, and particular to a press fitting method
applied to computer, electronic or LED lamp device or related heat
dissipating technology.
DESCRIPTION OF THE PRIOR ART
[0002] Heat pipe with heat sink are commonly used for the purpose
of providing a better heat dissipation to a computer, electronic or
LED lamp device. The heat sink is usually a heat conducting plate
(base) or a fin module. The heat sink is attached to a heat source
so that the heat will be quickly dissipated through the heat pipe
connected to the heat sink.
[0003] Prior fitting of the heat pipe and the fins of the heat sink
is through welding which is complicated method and also not
friendly to environment. Each fin needs to be welded with heated
intermediate. The flowing melting intermediate is hard to control a
well uniformity and gaps are sometimes happened so that the fitting
between the fins and the heat pipe is hard to achieve. Therefore,
the method is not economic.
[0004] Some maker will use conducting glue between the heat pipe
and the heat sink and as an adhesive. But the macromolecule glue
will be solidified by time and result in gaps so that the heat
dissipation will be effected.
SUMMARY OF THE INVENTION
[0005] Accordingly, the primary object of the present invention is
to provide a fitting method for heat pipe and heat sink which is
fast, effective, and economic so as to ensure the tight connection
and well heat dissipation.
[0006] Through the method, the production of the assembly is fast,
and the heat dissipation performance is also raised for the
needs.

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] In order that those skilled in the art can further
understand the present invention, a description will be provided in
the following in details. However, these descriptions and the
appended drawings are only used to cause those skilled in the art
to understand the objects, features, and characteristics of the
present invention, but not to be used to confine the scope and
spirit of the present invention defined in the appended claims.
[0012] Referring to FIG. 1A to 1D, the first embodiment of a press
fitting method for heat pipe and heat sink according to the present
invention is illustrated. The embodiment includes the following
steps.
[0013] a) At least a heat pipe 10 and a heat sink 20 conducting
heat to the heat pipe 10 are provided. The heat pipe 10 is
approximately oval-shaped. The heat sink 20 is one of a plate,
base, or fin module capable of conducting heat. The heat sink 20
has a groove 21 for receiving the heat pipe 10 on a side thereof.
The heat pipe 10 will be protruded from a surface of the heat sink
20 while being received by the groove 21.
[0014] b) The heat pipe 10 is placed into the groove 21. A
conductivity medium 30 is smeared around the junction of the heat
pipe 10 and the heat sink 20.
[0015] c) The end of the heat pipe 10 protruded from the groove 21
is pressed by a press mold 40 so as to be deformed and fit to the
groove 21 as one. (shown in FIG. 1D)
[0016] Through the above steps, the heat pipe 10 is tightly fitting
to the heat sink 20 so as to achieve a better heat dissipation.
[0017] Referring to FIGS. 2A to 2D, the second embodiment according
to the present invention is illustrated. The embodiment has
generally the same steps a, b, and c with the first embodiment.
[0018] The difference between the two embodiments is that a heat
pipe 10a of the second embodiment is below (or level with) the
surface of the heat sink 20 while being received by the groove 21
of the heat sink 20. The heat pipe 10a is placed into the groove
21. The conductivity medium 30 is smeared to the junction of the
heat pipe 10a and the heat sink 20. A press mold 40a has a
protrusion for the heat pipe 10a inside the groove 21. An end of
the heat pipe 10a pointing out the groove will be pressed by the
protrusion of the press mold 40a so as to be deformed and fit to
the groove 21.
[0019] Referring to FIG. 3A to 3E, the third embodiment of press
fitting method for heat pipe and heat sink according to the present
invention is illustrated. The embodiment includes the following
steps.
[0020] a) At least one heat pipe 50 and a heat sink 60 conducting
heat to the heat pipe 50 are provided. The heat pipe 50 is
approximately oval-shaped. The heat sink 60 has a plurality of fin
61. The plurality of fin 61 has a through hole 62 for receiving the
heat pipe 50.
[0021] b) The heat pipe 50 is placed into the through hole 62. A
conductivity medium 70 is smeared to the junction of the heat pipe
50 and the through hole 62. A jig 80 passing through the fins is
holding against one side of the heat pipe 50.
[0022] c) Another side of the heat pipe 50 against the jig 80 is
pressed by a press mold 82. The heat pipe 50 being pressed is
deformed towards the fins 61 so that the fins 61 and the heat pipe
50 will be tightly fit together (as shown in FIGS. 3D and 3E).
[0023] Referring to FIGS. 4A to 4D, the fourth embodiment according
to the present invention is illustrated. The embodiment has the
following steps a, b, and c generally the same with the third
embodiment.
[0024] a) At least one heat pipe 50 and a heat sink 60 conducting
heat to the heat pipe 50 are provided. The heat pipe 50 is
approximately oval-shaped. The heat sink 60 has a plurality of fin
61. The plurality of fin 61 has a through hole 62 for receiving the
heat pipe 50.
[0025] b) The heat pipe 50 is placed into the through hole 62. A
conductivity medium 70 is smeared to the junction of the heat pipe
50 and the through hole 62. A press mold 90 has an upper mold 91
and lower mold 92.
[0026] c) The upper mold 91 and the lower mold 92 is passing
through the fins 61 and pressing two opposite sides of the heat
pipe 50. The heat pipe 50 being pressed is deformed towards the
fins 61 so that the heat pipe 50 and the fins 61 will be tightly
fit together (as shown in FIG. 4b).
[0027] Referring to FIGS. 5A and 5B, the fifth embodiment according
to the present invention is illustrated. The embodiment has the
following steps a, b, and c generally the same with the third and
the fourth embodiments.
[0028] a) At least one heat pipe 50 and a heat sink 60 conducting
heat to the heat pipe 50 are provided. The heat pipe 50 is
approximately oval-shaped. The heat sink 60 has a plurality of fin
61. The plurality of fin 61 has a through hole 62 for receiving the
heat pipe 50. However, each of the fins 61 has a vertical extension
portion 63 capable of attaching to a surface of the heat pipe.
[0029] b) The heat pipe 50 is placed into the through hole 62 so
that the extension portions 63 of the fins 61 are attached to the
heat pipe 50. A conductivity medium 70 is smeared to the junction
of the heat pipe 50 and the extension portions 63. At least one
press mold 95 is provided.
[0030] c) The press mold 95 is pressing towards the extension
portions 63. The heat pipe 50 is thus pressed and deformed towards
the fins 61 so that the heat pipe 50 and the fins 61 will be
tightly fit together.
