Description
FIELD OF THE INVENTION
[0001] The present invention relates to a heat-dissipating device,
and more particularly to a heat-dissipating device for dissipating
internal heat generated from the heat-dissipating device.
BACKGROUND OF THE INVENTION
[0002] Heat-dissipation is always the crucial and essential problem
in application of electric products. A good heat-dissipating
mechanism usually represents a stable performance of the electric
device. On the other hand, an electric device operated under an
abnormal-dissipating condition will inevitably lead to an unstable
performance and reduce the operation life of the electric
device.
[0003] The heat-dissipating device generally has a motor for
driving the heat-dissipating mechanism. A typical motor includes a
rotator and a stator, wherein the rotator rotates circumambiently
around the stator. Therefore, the heat-dissipating device itself is
a source of heat. The heat generated by the rotation of the motor
increases temperature of the heat-dissipating device, which leads
to damage of the heat-dissipating device. In order to overcome the
foresaid problem, the present invention provides a heat-dissipating
device for dissipating internal heat generated from the
heat-dissipating device.
SUMMARY OF THE INVENTION
[0004] It is therefore an object of the present invention to
provide a heat-dissipating device for dissipating internal heat
generated from the heat-dissipating device.
[0005] In accordance with the present invention, the
heat-dissipating device includes a motor having a rotator and a
stator for causing the rotator to rotate, and a fan connected with
the rotator and having a hub having a slot and a plurality of holes
thereon for rotating and dissipating the heat.
[0006] The heat-dissipating device further includes a frame engaged
with the stator of the motor, and a circuit plate disposed in the
frame and electrically connected with the stator for driving the
rotator.
[0007] In addition, the fan further includes a plurality of blades
to be rotated in a direction so as to draw air from an interior of
the frame toward a front side of the fan.
[0008] In accordance with the present invention, the plurality of
holes are disposed in the slot for dissipating the internal heat
generated from the heat-dissipating device when the fan is
rotated.
[0009] It is another object of the present invention to provide a
heat-dissipating device for using in an electronic appliance to
dissipate first heat generated from components of the electronic
appliance and dissipate second heat generated from the
heat-dissipating device.
[0010] In accordance with the present invention, the
heat-dissipating device includes a fan having a hub having a slot
and a plurality of holes thereon, a rotator engaged in the hub of
the fan, and a stator for causing the rotator to rotate so as to
dissipate the first heat generated from components of the
electronic appliance and dissipate the second heat generated from
the heat-dissipating device.
[0011] In addition, the fan further includes a plurality of blades
to be rotated in a direction so as to draw air from an rear side of
the fan toward a front side of the fan.
[0012] Furthermore, the plurality of holes are disposed in the slot
for dissipating the first heat generated from components of the
electronic appliance and dissipating the second heat generated from
the heat-dissipating device.
[0013] It is another object of the present invention to provide a
fan rotator assembly for using in a heat-dissipating device having
a stator.
[0014] In accordance with the present invention, the fan rotor
assembly includes a fan having a hub having a slot and a plurality
of holes thereon, and a rotator engaged with the hub of the fan to
be driven by the stator for causing the fan to rotate so as to
dissipate heat generated from the heat-dissipating device.
[0015] Furthermore, the plurality of holes are disposed in the slot
for dissipating the heat generated from the heat-dissipating
device.
[0016] The present invention may best be understood through the
following descriptions with reference to the accompanying drawings,
in which:
BRIEF DESCRIPTION OF THE DRAWINGS
[0017] FIG. 1 is a schematic diagram illustrating the
heat-dissipating device according to the preferred embodiment of
the present invention; and
[0018] FIG. 2 is a schematic view showing the fan rotator assembly
according to the preferred embodiment of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] Please refer to FIG. 1 and FIG. 2. The heat-dissipating
device includes a motor, a fan 4 with a plurality of blades, a
frame 5 and a circuit plate 6. In addition, the motor includes a
stator 1 and a rotator 2, and the fan 4 includes a hub 3 having a
slot 7 thereon. Certainly, the stator 1 further includes a coil
(not shown), and the rotator further includes a magnet ring 8.
There are a plurality of holes 9 disposed in the slot 7 of the hub
3.
[0020] When the heat-dissipating device is in operation, air is
drawn from an interior of the frame 5 toward a front side of the
fan 4. In the meanwhile, heat-dissipating currents are through the
holes 9 disposed in the slot 7 of the hub 3. Therefore, the
internal heat generated from the coil of the heat-dissipating
device could be dissipated. The temperature of the motor of the
heat-dissipating device could be reduced. In addition, because the
holes 9 are disposed in the slot 7, which is an inner part of the
heat-dissipating device, dust would not be drawn easily into the
motor while the fan 4 is rotating.
[0021] Accordingly, the present invention provides a
heat-dissipating device for dissipating the internal heat generated
from the heat-dissipating device. Therefore, the performance of the
motor could be maintained well and the operation life of the
heat-dissipating device is prolonged.
[0022] While the invention has been described in terms of what are
presently considered to be the most practical and preferred
embodiments, it is to be understood that the invention need not be
limited to the disclosed embodiment. On the contrary, it is
intended to cover various modifications and similar arrangements
included within the spirit and scope of the appended claims which
are to be accorded with the broadest interpretation so as to
encompass all such modifications and similar structures. Therefore,
the above description and illustration should not be taken as
limiting the scope of the present invention which is defined by the
appended claims.
