Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to air conduction devices,
and particularly to an air conduction device used in a
computer.
[0003] 2. Description of Related Art
[0004] Electronic devices, such as computers, use heat dissipation
assemblies for dissipating heat generated by components therein,
thus preventing the components from becoming overheated. An air
conduction device is often used in a computer with a fan to assist
in heat dissipation. The air conduction device includes an airduct
covering the heat generating components of the computer, and a fan
installed at or near the inlet of the airduct to generate airflow
to dissipate heat from the heat generating components covered by
the airduct. However, airflow from the airduct is non-variant, if
the heat generating components generate more heat, the components
may still be overheated, which may harm the components.
BRIEF DESCRIPTION OF THE DRAWINGS
[0005] Many aspects of the present embodiments 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 present embodiments. Moreover, in the drawings, all the views
are schematic, and like reference numerals designate corresponding
parts throughout the several views.
[0006] FIG. 1 is an exploded, isometric view of an air conduction
device, and a circuit board with two heat sinks and two heat
generating members.
[0007] FIG. 2 is an assembled, isometric view of the air conduction
device and the circuit board of FIG. 1.
[0008] FIGS. 3 and 4 are cross-sectional views of FIG. 2, but
respectively showing different usage states of the air conduction
device.
DETAILED DESCRIPTION
[0009] The disclosure, including the accompanying drawings, is
illustrated by way of examples and not by way of limitation. 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, an air conduction device is
provided to dissipate heat from a first heat generating member 10
and a second heat generating member 20 mounted on a circuit board
11 of an electronic apparatus. The air conduction device includes a
main body 30, and first and second adjusting members 40.
[0011] A first heat sink 13 and a second heat sink 14 are mounted
to the circuit board 11. The first heat sink 13 is adjacent to the
first heat generating member 10 and diagonal to the second heat
sink 14, and aligns with the second heat generating member 20. The
second heat sink 14 is adjacent to the second heat generating
member 20, and aligns with the first heat generating member 10.
[0012] The main body 30 includes a top plate 31, and two side
plates 32 extending downward from opposite sides of the top plate
31. A plurality of protrusions 322 extends from a bottom of each
side plate 32. A clapboard 33 extends downward from the top plate
31, between the side plates 32, therefore, a first passage 35 and a
second passage 34 are formed between the clapboard 33 and the side
plates 32. A plurality of protrusions 332 extends from a bottom of
the clapboard 33. The top plate 31 defines a substantially
trapezoid-shaped cutout 36 communicating with the first passage 35.
The cutout 36 includes two opposite slanted sidewalls 362 connected
between the clapboard 33 and the corresponding side plate 32. Each
slanted sidewall 362 defines a plurality of slots 364 aligned in a
slanting line from an upper portion to a lower portion of the
slanted sidewall 362. Two bar-shaped guide members 334 extend from
the clapboard 33, facing the cutout 36. Each guide member 334 is
adjacent and parallel to the corresponding slanted sidewall
362.
[0013] Each adjusting member 40 includes a substantially L-shaped
connection portion 42 and a lock portion 44. The connection portion
42 includes a connection board 422 and a guide board 424
substantially extending down from a side of the connection board
422. A depressed portion 426 is defined in the connection potion
42, extending from a first side of the connection board 42 opposite
to the lock portion 44 to the guide board 424. A gap 43 is defined
between the connection board 422 and a side of the depressed potion
426 opposite to the guide board 424.
[0014] The lock portion 44 slantingly extends from a second side of
the connection board 422 opposite to the first side, at an angle
equaling to the slanting angle of the corresponding slanted
sidewall 362. An elastic hook 442 extends from the lock portion
44.
[0015] Referring to FIG. 2, in assembly, the connection board 422
of the second adjusting member 40 extends through the gap 43 of the
first adjusting member 40. Therefore, the adjusting members 40 are
mounted together, and slidable relative to each other along a
length direction of the gap 43. The guide boards 424 can be
adjusted to slide to resist against each other. The lock portions
44 can be moved towards or away from each other, while the
adjusting members 40 are slid. The adjusting members 40 are
received in the cutout 36. The lock portion 44 of each adjusting
member 40 is sandwiched between the guide member 334 and the
slanted sidewall 362, and the lock portion 44 is slidable along the
slanted sidewall 362. The elastic hook 442 is selectively engaged
in any one of the slots 364, and the guide boards 424 of the
adjusting members 40 abut against an inner side of the side plate
32. Ends of the adjusting members 40 opposite to the corresponding
guide boards 424 resist against the clapboard 33.
[0016] In use, the protrusions 322 and 332 are engaged in the
circuit board 11, and the main body 30 of the air conduction device
covers the first and second heat generating members 10 and 20, and
the first and second heat sinks 13 and 14. The first heat
generating member 10 and the second heat sink 14 are accommodated
in the second passage 34. The second heat generating member 20 and
the first heat sink 13 are accommodated in the first passage 35,
and the cutout 36 of the main body 30 is located above the second
heat generating member 20.
[0017] Referring to FIGS. 3 and 4, the adjusting members 40 are
slid relative to each other, with the lock portions 44 sliding up
or down along the slanted sidewall 362, to move the connection
boards 422 of the adjusting members 40 up or down relative to the
second heat generating member 20. Therefore, a distance between the
second heat generating member 20 and the connection boards 422 can
be adjusted, to adjust airflow flowing through the first and second
passage 35 and 34. After the adjusting members 40 are moved to an
appropriate height, the elastic hook 442 of each adjusting member
40 is engaged in a corresponding one of the slots 364.
[0018] It is believed that the present embodiments and theirs
advantages will be understood from the foregoing description, and
they will be apparent that various changes may be made thereto
without departing from the spirit and scope of the description or
sacrificing all of their material advantages, the examples
hereinbefore described merely being exemplary embodiment.
