Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure generally relates to air directors
for electronic devices, and particularly to an air director with a
baffle for avoiding unwanted flow of heated air.
[0003] 2. Description of Related Art
[0004] Recent further development of electronic devices has sought
to satisfy the elevated consumer demand for faster operation speeds
and more compact portable electronic devices. As a result, the heat
dissipation performance of many electronic devices is now of vital
importance. Common electronic devices employ fans for driving air
to flow over heat generating components, with the airflow passing
through an air inlet and an air outlet located in an outer shell of
the electronic device. However, for achieving compactness and an
aesthetic design, the air inlet and air outlet are usually
configured on a common sidewall of the outer shell. This allows
heated air exiting the air outlet to be drawn back into the air
inlet, which decreases the heat dissipating efficiency of the
airflow system.
[0005] Therefore, it is necessary to provide a means for overcoming
the above-mentioned shortcomings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] Many aspects of the disclosure can be better understood with
reference to the following drawings. The components in the drawings
are not necessarily drawn to scale, the emphasis instead being
placed upon clearly illustrating the principles of the
disclosure.
[0007] FIG. 1 is a schematic, isometric view of an air director in
accordance with an exemplary embodiment of the present
disclosure.
[0008] FIG. 2 is a view of the air director of FIG. 1 with a top
plate thereof removed, and showing an electronic device capable of
being received in the air director.
DETAILED DESCRIPTION
[0009] Reference will now be made to the drawings to describe an
exemplary embodiment of the present air director.
[0010] Referring to FIG. 1 and FIG. 2, an air director 10, in this
embodiment, includes a top plate 11, a bottom plate 12, four side
plates 13, an air baffle 14, an air inlet 15 and an air outlet
16.
[0011] The top plate 11 and the bottom plate 12 are general planar
and opposite to each other. In this embodiment, the top plate 11 is
parallel to the bottom plate 12.
[0012] The four side plates 13 are connected together end to end,
and connected between the top plate 11 and the bottom plate 12. The
four side plates 13 have their upside edges and downside edges
respectively connected with the top plate 11 and the bottom plate
12. Thereby, the top plate 11, the bottom plate 12 and the four
side plates 13 cooperatively define a receiving chamber 100
therebetween. The receiving chamber 100 is for receiving an
electronic device 20, thereby protecting the electronic device 20.
It is to be noted that the air director 10 is not limited to
including the four side plates 13. The air director 10 can instead
be equipped with three, five, six or more side plates.
[0013] The air baffle 14 is configured on an outer surface 130 of
one side plate 13. The air baffle 14 longitudinally extends along
the outer surface 130, respectively towards the top plate 11 and
the bottom plate 12. In this embodiment, the air baffle 14 is
integrally formed with the side plate 13. It is noted that the air
baffle 14 can have a profile of a straight line or a curved line.
In this embodiment, the air baffle 14 has a profile of a straight
line, and extends along an axis perpendicular to the top plate 11
and the bottom plate 12.
[0014] The air inlet 15 and the air outlet 16 are both configured
at the outer surface 130 of the side plate 13 which supports the
air baffle 14. The air inlet 15 is located on one side of the air
baffle 14, and the air outlet 16 is located on another opposite
side of the air baffle 14. That is, the air inlet 15 and the air
outlet 16 are respectively located at opposite lateral sides of the
air baffle 14.
[0015] Due to the air baffle 14 being located between the air inlet
15 and the air outlet 16, the air baffle 14 blocks heated air
exiting the air outlet 16 from being drawn back into the air inlet
15. Thereby, a decrease in the heat dissipating efficiency of the
electronic device 20 caused by recirculation of heated air is
avoided.
[0016] It is to be noted that the air director 10 can further
include a first air guiding plate 17 and a second air guiding plate
18 configured on the outer surface 130 of the side plate 13 which
supports the air baffle 14. The first air guiding plate 17 and the
second air guiding plate 18 are respectively located at opposite
top and bottom ends of the air baffle 14. In this embodiment, the
first air guiding plate 17 is adjacent to the top plate 11, and the
second air guiding plate 18 is adjacent to the bottom plate 12.
Also, in this embodiment, the first air guiding plate 17 and the
second air guiding plate 18 are both integrally formed with the air
baffle 14.
[0017] It is also to be noted that the first and second air guiding
plates 17, 18 each can have a profile of a straight line or a
curved line, as long as the first and second air guiding plates 17,
18 guide heated air along directional paths leading away from the
air inlet 15, and further guide air in the vicinity of the air
inlet 15 along directional paths leading away from the heated
air.
[0018] In this embodiment, the first air guiding plate 17 has a
profile of a straight line, and extends along an axis parallel to
the top plate 11. The second air guiding plate 18 has a profile of
a straight line, and extends along an axis parallel to the bottom
plate 12. Detailedly, the first air guiding plate 17
perpendicularly extends in two opposite directions from the top end
of the air baffle 14, and the second air guiding plate 18
perpendicularly extends in two opposite directions from the bottom
end of the air baffle 14.
[0019] Furthermore, the air baffle 14 can be configured with the
top end thereof contacting the top plate 11. In this case, the
first air guiding plate 17 is configured on a joint of the top
plate 11 and the side plate 13 where the top end of the air baffle
14 is located. Moreover, the air baffle 14 can be configured with
the bottom end thereof contacting the bottom plate 12. In this
case, the second air guiding plate 18 is configured on a joint of
the bottom plate 12 and the side plate 13 where the bottom end of
the air baffle 14 is located.
[0020] In the present embodiment, one reason for the first and
second air guiding plates 17, 18 being configured to extend along
directions perpendicular to the air baffle 14 is for aesthetic
design. It is to be noted that in alternative embodiments, the
first and second air guiding plates 17, 18 can be configured to
extend along slantwise directions relative to the air baffle
14.
[0021] In addition, the air director 10 can further include a
baffle plate 19 extending from an interior surface 132 of the side
plate 13 which supports the air baffle 14. The baffle plate 19
contacts a portion of the interior surface 132 of the side plate 13
between the air inlet 15 and the air outlet 16. The baffle plate 19
extends into the receiving chamber 100 and divides the receiving
chamber 100 into two chamber portions 102, 104 respectively on the
left side and the right side of the baffle plate 19. The two
chamber portions 102, 104 communicate with each other at a distal
end of the baffle plate 19. In this case, a length of the passage
for airflow in the receiving chamber 100 is extended, thereby
increasing the heat exchange utilization efficiency of the airflow.
In the present embodiment, the baffle plate 19 is integrally formed
with both the side plate 13 and the bottom plate 12.
[0022] It is to be understood that the above-described embodiments
are intended to illustrate rather than limit the disclosure.
Variations may be made to the embodiments without departing from
the spirit of the disclosure as claimed. The above-described
embodiments illustrate the scope of the disclosure but do not
restrict the scope of the disclosure.
