FAN ASSEMBLY
Abstract
A fan assembly includes a fan and a number of guiding boards.
The fan includes an end board defining a vent. The guiding boards
have different weights and are pivotably mounted to the side board
from top to bottom and from lightest to heaviest. The guiding
boards cooperatively cover or uncover the vent.

Claims
1. A fan assembly, comprising: a fan comprising a side board
defining a vent ; and a plurality of guiding boards to cover or
uncover the vent, wherein the plurality of guiding boards have
different weights and are pivotably mounted to the side board from
top to bottom and arranged in a lightest to heaviest order from top
to bottom.
2. The fan assembly of claim 1, wherein two fixing pieces protrude
from opposite sides of the side board, each fixing piece
longitudinally defines a plurality of fixing holes, two pins extend
from opposite end portions of a top portion of each guiding board
to be pivotably received in two aligning fixing holes.
3. A fan assembly, comprising: a fan comprising a side board
defining a vent ; and a plurality of guiding boards to cover or
uncover the vent, wherein the plurality of guiding boards have
different weights and are pivotably mounted to the side board from
top to bottom.
Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to a fan assembly.
[0003] 2. Description of Related Art
[0004] For a conventional fan assembly, weights of guiding boards
mounted to fans are the same. As a result, when the fans operate,
the guiding boards extend away from the fans at same angles. Thus,
airflow generated by the fans is directed toward a same distance
away from the fan, so elements further away from the fan may not be
effectively cooled.
BRIEF DESCRIPTION OF THE DRAWING
[0005] Many aspects of the present embodiments can be better
understood with reference to the following drawing. The components
in the drawing are not necessarily drawn to scale, the emphasis
instead being placed upon clearly illustrating the principles of
the present embodiments. Moreover, in the drawing, the view is
schematic.
[0006] The FIGURE is an assembled, isometric view of an embodiment
of a fan assembly.
DETAILED DESCRIPTION
[0007] The disclosure, including the accompanying drawings, is
illustrated by way of example 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."
[0008] The FIGURE shows an embodiment of a fan assembly 10
comprising a fan 20 and a plurality of guiding boards 100.
[0009] The fan 20 comprises a side board 22. A substantially
central portion of the side board 22 defines a vent 24. Two fixing
pieces 26 protrude substantially perpendicularly from opposite
sides of the side board 22, respectively. Each fixing piece 26
defines a plurality of fixing holes 260 along a lengthwise
direction thereof.
[0010] Two pins 102 extend from opposite end portions,
respectively, of a top portion of each guiding board 100. The two
pins 102 of each guiding board 100 are received in a corresponding
pair of fixing holes 260 to pivotably mount the guiding board 100
to the fan 20.
[0011] The guiding boards 100 cooperatively cover or uncover the
vent 24 like a window shutter. The guiding boards 100 comprise a
heaviest first board 30, a second heaviest second board 40, a third
heaviest third board 50, and a fourth heaviest fourth board 60. The
guiding boards 100 are arranged on the side board 22 from top to
bottom and from lightest to heaviest. Thus, the first board 30 is
located at a lowest portion of the side board 22, and the fourth
board 60 is located at a topmost portion of the side board 22.
[0012] When the fan 20 is not operating, the guiding boards 100 are
substantially parallel to the side board 22 and cover the vent
24.
[0013] When the fan 20 operates, airflow generated by the fan 20
pushes the guiding boards 100 to rotate away from the side board
22, thereby making the guiding boards 100 slant relative to the
side board 22 at different angles. The guiding boards 100 slant at
different angles corresponding to their respective weights, and
airflow is directed toward different distances from the fan 20. The
fourth board 60 (the lightest guiding board 100) slants at the
greatest angle, and the first board 30 (the heaviest guiding board
100) slants at the smallest angle.
[0014] It is believed that the present embodiments and their
advantages will be understood from the foregoing description, and
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 embodiments.
