Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to a series fan
structure, and more particularly to a series fan structure in a
symmetrical form. The frame bodies of the series fan structure can
be made with single mold and assembled to form the symmetrical
series fan structure. In this case, the mold development cost is
saved and the manufacturing cost is lowered.
[0003] 2. Description of the Related Art
[0004] Recently, the internal circuits of the integrated circuit
(IC) chip have been laid out more and more compactly. Consequently,
the chip generates higher and higher heat. When a personal computer
works, the compact IC chip such as CPU or graphics chip will
generate high heat. In order to keep the IC chip functioning
lastingly, it is necessary to maintain the IC chip at an optimal
working temperature. In this case, rise of temperature can be
avoided so as not to deteriorate the efficiency of the IC chip or
damage the IC chip. In general, a heat dissipation device is used
to directly contact the surface of the electronic component for
dissipating the heat generated by the electronic component.
Accordingly, the electronic component can keep working normally
without shortening its lifetime.
[0005] A cooling fan is an inevitable component of a heat
dissipation device. The cooling fan is able to quickly carry away
the heat absorbed by a radiating fin assembly to complete a thermal
cycle and achieve better heat dissipation effect.
[0006] In general, two cooling fans are serially connected with
each other to dissipate the heat generated by a heat source. Under
such circumstance, in case one of the cooling fans fails, the other
cooling fan can still operate to dissipate the heat so as to avoid
damage of the heat source due to overheating. Moreover, in an
operation system with high static pressure, the series cooling fan
has better performance and is able to provide higher wind
intensity.
[0007] FIG. 1A is a perspective exploded view of a conventional
series fan. FIG. 1B is a perspective assembled view of the
conventional series fan. The series fan 1 includes a first frame
body 10 and a second frame body 11. The first frame body 10 has a
first base 101 on one side. The first base 101 is connected to the
first frame body 10 via multiple first connection members 102 in
arcuate form. In addition, the first base 101 is formed with
multiple fixing holes 103.
[0008] The second frame body 11 has a second base 111 on one side.
The second base 111 is connected to the second frame body 11 via
multiple second connection members 112 in arcuate form. In
addition, the second base 111 is formed with multiple fixing
members 113. The fixing members 113 can be connected to the fixing
holes 103 to serially connect the first and second frame bodies 10,
11. In this case, the bottoms of the first base 101 and the first
connection members 102 are respectively attached to the bottoms of
the second base 111 and the second connection members 112 to form
the series fan 1. According to the above arrangement, the first and
second frame bodies 10, 11 are respectively formed with male and
female fixing structures. Moreover, the first and second connection
members 102, 112 are arcuate members directed in different
directions. Therefore, it is necessary to use two sets of molds to
manufacture the first and second frame bodies 10, 11. This leads to
increase of mold development cost and manufacturing cost.
Accordingly, the conventional series fan has the following
shortcomings:
[0009] 1. The mold development cost is increased.
[0010] 2. The manufacturing cost is increased.
SUMMARY OF THE INVENTION
[0011] A primary object of the present invention is to provide a
symmetrical series fan structure. The frame bodies of the
symmetrical series fan structure can be made with single mold and
assembled to form the symmetrical series fan structure.
Accordingly, the mold development cost is saved to lower the
manufacturing cost.
[0012] To achieve the above and other objects, the symmetrical
series fan structure of the present invention includes multiple
frame bodies. Each frame body has a first through hole, a second
through hole and a base. The first and second through holes are
respectively formed on two sides of the frame body. Multiple
connection members extend from a circumference of the base. The
base is positioned in the second through hole and connected to the
frame body via the connection members. In addition, the frame body
has multiple fixing members and multiple fixing holes on the same
side of the frame body as the base. The frame bodies are serially
connected by means of inserting the fixing members into the fixing
holes with the base and the connection members of one frame body
attached to the base and the connection members of another frame
body. Accordingly, the frame bodies can be made with single mold
and serially assembled to form the symmetrical series fan
structure. In this case, the mold development cost is saved and the
manufacturing cost is lowered. Accordingly, the present invention
has the following advantages:
[0013] 1. The mold development cost is saved.
[0014] 2. The manufacturing cost is lowered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0024] Please refer to FIGS. 2 and 3. FIG. 2 is a perspective
exploded view of a first embodiment of the symmetrical series fan
structure of the present invention. FIG. 3 is a perspective
assembled view of the first embodiment of the symmetrical series
fan structure of the present invention. The symmetrical series fan
structure 2 includes multiple frame bodies 30. In this embodiment,
the symmetrical series fan structure 2 includes two frame bodies
30, which are serially connected and assembled with each other.
Each frame body 30 has a first through hole 301, a second through
hole 302 and a base 303. The first and second through holes 301,
302 are respectively formed on two sides of the frame body 30. A
flow way 304 is formed between the first and second through holes
301, 302. Multiple connection members 3031 extend from a
circumference of the base 303 in straight form. The base 303 is
positioned in the second through hole 302 and connected to the
frame body 30 via the connection members 3031. In addition, the
frame body 30 has multiple fixing members 305 and multiple fixing
holes 306 on the same side of the frame body 30 as the base 303. In
this embodiment, the fixing members 305 and fixing holes 306 are
diagonally disposed on one side of the frame body 30 with the base
303.
[0025] The frame bodies 30 are formed by means of single mold. When
serially connecting two frame bodies 30, one of the frame bodies 30
is turned over and rotated to assemble with the other. Under such
circumstance, the two frame bodies 30 are assembled with the second
through holes 302 aligned with and immediately adjacent to each
other. Also, the fixing members 305 of one frame body 30 are aimed
at the fixing holes 306 of the other frame body 30 and inserted
into the fixing holes 306. Accordingly, the corners of one frame
body 30 are respectively affixed to the corners of the other frame
body 30 with the bases 303 and connection members 3031 of the two
frame bodies 30 attached to each other and with the flow ways 304
of the two frame bodies 30 in good communication with each other.
Accordingly, the frame bodies 30 can be made with single mold and
assembled to form the symmetrical series fan structure 2. This can
save the mold development cost and lower the manufacturing
cost.
[0026] Please now refer to FIGS. 5 and 6. FIG. 5 is a perspective
exploded view showing the application of the first embodiment of
the symmetrical series fan structure of the present invention. FIG.
6 is a perspective assembled view showing the application of the
first embodiment of the symmetrical series fan structure of the
present invention. Two fan impellers 40 are respectively disposed
in the first through holes 301 of the frame bodies 30 to form the
symmetrical series fan structure 2 with dynamic blades and static
blades alternately arranged. This can increase wind intensity and
enhance performance of the fan impellers 40.
[0027] Please now refer to FIG. 7, which is a perspective exploded
view of a second embodiment of the symmetrical series fan structure
of the present invention. The second embodiment is substantially
identical to the first embodiment in structure and connection
relationship between the components and thus will not be repeatedly
described hereinafter. The second embodiment is different from the
first embodiment in that the fixing members 305 of one side of the
frame body 30 are positioned on the same lateral side rather than
diagonally arranged and the fixing holes 306 are positioned on
another lateral side opposite to the fixing members 305. In this
case, the frame bodies 30 can be also formed by means of single
mold. When serially connecting two frame bodies 30, the fixing
members 305 of one frame body 30 are aimed at the fixing holes 306
of the other frame body 30 and inserted into the fixing holes 306.
Also, the bases 303 and connection members 3031 of the two frame
bodies 30 attached to each other with the flow ways 304 of the two
frame bodies 30 in good communication with each other. Accordingly,
the frame bodies 30 can be made with single mold and assembled to
form the symmetrical series fan structure 2. This can save the mold
development cost and lower the manufacturing cost.
[0028] The above embodiments are only used to illustrate the
present invention, not intended to limit the scope thereof. It is
understood that many changes and modifications of the above
embodiments can be made without departing from the spirit of the
present invention. The scope of the present invention is limited
only by the appended claims.
