Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to heat dissipation
apparatuses, particularly to a heat dissipation apparatus for an
electronic device.
[0003] 2. Description of Related Art
[0004] Heat dissipating apparatus performs critical functions of
removing heat from a computer system. A Balanced Technology
Extended (BTX) dissipating apparatus may be used in a Small Form
Factor (SFF) computer chassis, wherein the SFF has a small volume.
The BTX dissipating apparatus includes a heat dissipating device
and a fan. However, an additional securing member is needed to
secure the fan to the device. Therefore, there is room for
improvement within the art.

DETAILED DESCRIPTION
[0010] 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.
[0011] Referring to FIGS. 1 and 2, a heat dissipation apparatus in
accordance with an embodiment includes a heat dissipating device
10, a fan 20 and an air guiding duct 30.
[0012] The heating dissipating device 10 includes a heat conduction
core 11 and a plurality of fins 12 around the heat conduction core
11. Each of the plurality of fins 12 is arcuate. Four pairs of
securing fin assemblies 125 are evenly arranged among the plurality
of fins 12. Each of the four pairs of securing fin assemblies 125
includes a first securing fin 121 and a second securing fin 123
adjacent to the first securing fin 121. The first securing fin 121
and the second securing fin 123 all extend out of the plurality of
fins 12, and a length of the first securing fin 121 is less than
that of the second securing fin 123. A first securing hole 124 is
defined in the first securing fin 121, and a second securing hole
126 is defined in the second securing fin 123. In one embodiment,
the first securing hole 124 includes a cutout (not labeled).
[0013] The fan 20 includes an outer frame 21, and a receiving hole
201 is defined in the outer frame 21. A plurality of fan blades 202
are received in the receiving hole 201. The outer frame 21 includes
a top panel 23 and bottom panel 24. The top panel 23 defines four
mounting holes 231 arranged at the four corners of the top panel
23. Four fixing holes 241, arranged at the four corners of the
bottom panel 24, are defined in the bottom panel 24. The four
fixing holes 241 correspond to the first securing holes 124.
[0014] The air guiding duct 30 is hollow and defines an air guiding
opening 31. Four securing posts 32 and four clipping portions 34
extend from a side of the air guiding duct 30. Each of the four
clipping portions 34 is adjacent to each of the four securing posts
32. In one embodiment, a cross-section of the air guiding duct 30
is rectangular, and the air guiding opening 31 is rectangular. A
size of the air guiding opening 31 is substantially equal to that
of the receiving hole 201.
[0015] Referring to FIGS. 1-3, in assembly, the bottom panel 24 is
placed on the heat dissipating device 10. The four fixing holes 241
are aligned with the four first securing holes 124. Four fixing
members 90 are engaged in the four fixing holes 241 and the four
first securing holes 124, to secure the fan 20 to the heat
dissipating device 10. When the fixing member 90 is received in the
first securing hole 241, a size of the cutout may be increased.
[0016] The four securing posts 32 are engaged in the four mounting
holes 231, and the four clipping portions 34 are engaged with the
top panel 23, to secure the air guiding duct 30 to the fan 20. At
this point, the air guiding opening 31 corresponds to the fan
20.
[0017] Referring to FIG. 4, the heat dissipating apparatus can be
attached to a circuit board 50. The circuit board 50 includes a
heat generating component 51, and four positioning holes 53 are
defined in the circuit board 50 and around the heat generating
component 51.
[0018] When the heat dissipating apparatus is secured to the
circuit board 50, the heat conduction core 11 abuts the heat
generating component 51. The four second securing holes 126 are
aligned with the four positioning holes 53. Four mounting members
70 are engaged in the four second securing holes 126 and the four
positioning holes 53, to secure the heat dissipating apparatus to
the circuit board 50. The heat generated by the heat generating
component 51 is transmitted to the heat conduction core 11. The
heat conduction core 11 transmits the heat to the plurality of fins
12. The fan 20 can dissipate the heat from of the plurality of fins
12 via the air guiding opening 31.
[0019] 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
of shape, size, and arrangement of parts within the principles of
the disclosure to the full extent indicated by the broad general
meaning of the terms in which the appended claims are
