Description
BACKGROUND
[0001] 1. Technical Field
[0002] The disclosure generally relates to a heat sink apparatus
with heat pipes.
[0003] 2. Description of Related Art
[0004] Electronic components in computers, such as central
processing units (CPUs), may generate a lot of heat during normal
operations. Excess heat may deteriorate the operational stability
of the electronic components and may damage the electronic
components. Thus, excess heat must be removed quickly to maintain
an acceptable operating temperature of the CPUs and other
electronic components in the computers. One known method for
removing heat from the CPU is by mounting a heat sink apparatus on
the CPU. Such heat sink apparatus may include a heat sink and a
plurality of heat pipes mounted on the heat sink. However, the heat
pipes may easily come into contact other electronic elements in the
computer which may cause undesirable effects on the other
electronic elements.
[0005] Thus, there is room for improvement within the art.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] FIG. 1 is an exploded, isometric view of an embodiment of a
heat sink apparatus according to present disclosure.
[0007] FIG. 2 is another view of the heat sink apparatus of FIG.
1.
[0008] FIG. 3 is an assembled view of FIG. 1.
DETAILED DESCRIPTION
[0009] The disclosure is illustrated by way of example and not by
way of limitation in the figures of the accompanying drawings in
which like references indicate similar elements. It should be noted
that references to "an" or "one" embodiment in this disclosure are
not necessarily to the same embodiment, and such references mean at
least one.
[0010] Referring to FIGS. 1 and 2, one embodiment of a heat sink is
shown. The heat sink may include a base 10, a fin module 20, a
first heat pipe 30, and a second heat pipe 40.
[0011] The first heat pipe 30 may include a first receiving portion
301, a first body 302, and a first connecting portion 303. The
first connection portion 303 has a first end connected to the first
receiving portion 301, and a second end connected to the first body
302. The first receiving portion 301 is in contact with an upper
surface of the base 10 to carry the excess heat away from a heat
generating element. The first body 302 extends through the fin
module 20 to deliver the excess heat to the fin module 20 for
dispersion. The first receiving portion 301, the first body 302,
and the first connecting portion 303 may be on a first plane. The
first heat pipe 30 may has a U-shaped cross-section, taken along
the first plane.
[0012] The second heat pipe 40 may include a second receiving
portion 401, a second body 402, and a second connecting portion
403. The second connection portion 403 has a first end connected to
the second receiving portion 401, and a second end connected to the
second body 402. The second receiving portion 401 is in contact
with the upper surface of the base 10 to carry the excess heat away
from a heat generating element. The second body 402 extends though
the fin module 20 to deliver the excess heat to the fin module 20
for dispersion. The second receiving portion 401, the second body
402, and the second connecting portion 403 may be on a second
plane. The second heat pipe 40 may has a U-shaped cross-section,
taken along the second plane.
[0013] A lower surface of the base 10 may be used for contacting
the heat generating element, such as a CPU. The upper surface of
the base 10 may comprises a first slot 101 and a second slot 102.
The first slot 101 and the second slot 102 may have U-shaped
cross-sections, taken along a plane substantially perpendicular to
the upper surface of the base 10. The first slot 101 may be
substantially parallel to the second slot 102.
[0014] The fin module 20 includes a plurality of fins 201. Each of
the plurality of fins 201 is substantially perpendicular to the
base 10. The fin module 20 may further comprise a first through
hole 202 and a second through hole 203. A distance, measured on a
plane perpendicular to the upper surface of the base 10, between
the first through hole 202 and the second through hole 203 is
greater than that between the first slot 101 and the second slot
102. The fin module 20 may further comprise a first association
slot 204 and a second association slot 205, wherein the first
association slot 204 and the second association slot 205 are
relatively located to match the first slot 101 and the second slot
102, respectively. The first association slot 204 and the second
association slot 205 may have U-shaped cross-sections, taken along
a plane substantially perpendicular to the upper surface of the
base 10.
[0015] Referring to FIG. 3, in assembly, the fin module 20 is
placed on the base 10 with the first association slot 204 and the
second association slot 205 aligned with the first slot 101 and the
second slot 102, respectively. The first slot 101 and the first
association slot 204 form a first space 103. The second slot 102
and the second association slot 205 form a second space 104. The
first receiving portion 301 of the first heat pipe 30 is inserted
into the first space 103, and the first body 302 is inserted into
the first through hole 202 in a first direction. The second
receiving portion 401 of the second heat pipe 40 is inserted into
the second space 104, and the second body 402 is inserted into the
second through hole 203 in a second direction. The first direction
is substantially opposite to the second direction. An angle between
the first plane of the first heat pipe 30 and the second plane of
the second heat pipe 40 may be less than 90 degrees. The first
connecting portion 303 of the first heat pipe 30 and the second
connecting portion 403 are disposed on opposite side walls of the
fin module 20. The first body 302 and the second body 402 are
substantially perpendicular to the plurality of fins 201.
[0016] It is to be understood, however, that even though numerous
characteristics and advantages have been set forth in the foregoing
description of embodiments, together with details of the structures
and functions of the embodiments, the disclosure is illustrative
only, and changes may be made in detail, especially in the matters
