Description
FIELD OF THE INVENTION
[0001] The invention relates to a blade wheel structure, which is
disposed on a cooling device and featured by dissipating heat and
driving power at the same time to provide a more effective cooling
structure.
BACKGROUND OF THE INVENTION
[0002] As shown in Appendix 1, Taiwan Patent Publication No.
M252992 "Water-cooling system" is applied to a heating electronic
component including a cooling foundation 1, a water pump 3, a first
cooling base 4 and a second cooling base 5.
[0003] The mentioned parts are connected with a cycling pipeline 2
to form a closed loop for circulating low-temperature liquid. The
water pump 3 is the power source driving the low-temperature liquid
to circulate so that the low-temperature liquid continuously
circulates through all parts to perform heat exchange.
[0004] Besides, the cooling foundation 1 is disposed on a heating
electronic component. The first cooling base 4 and the second
cooling base 5 are disposed two heat sinks (41, 51) and two cooling
fans (42, 52) thereon respectively. The heat sinks (41, 51) absorb
the heat from the first cooling base 4 and the second cooling base
5. The cooling fans (42, 52) assist to dissipate the heat absorbed
by the heat sinks (41, 51) so as to achieve the circulating and
cooling effect.
[0005] Whereas, such conventional water-cooling cooling system is
barely in volume production and retailed simply because of the
numerous parts, bulky size, high production cost and the most
critical reason that fails to integrate the entire power.
[0006] The power owned the water-cooling system comes from the
cooling fans (42, 52) and the water pump 3. The cooling fans (42,
52) are featured by assisting the heat sinks (41, 51) to dissipate
heat while the water pump is featured by driving the
low-temperature liquid, signifying that the functions of both parts
are mutually independent.
[0007] Perhaps because the cooling fans 42 and 52 and the water
pump 3 all have their independently-own power, it winds out with
rather complicated and plentiful parts to integrate the
water-cooling system, bulky size and relatively high production
cost.
[0008] Consequently, if the power owned by the cooling fan and the
water pump can be unified and simplified as a whole, the size of
the water-cooling system can be further reduced, so can the
production cost.
SUMMARY OF THE INVENTION
[0009] In view of this, the invention thus provides a blade wheel
structure enabling to simultaneously dissipate heat and drive
power, which simplifies the composition of the cooling module,
reduces the entire size, saves production cost, and provides the
more effective cooling effect.
[0010] The blade wheel structure includes a hub having a circular
end face on the topside of the hub and there is a spindle
vertically connected at a center beneath the circular end face. A
circular sidewall extending downwardly from the circular end face
is disposed a plurality of blades thereon. There is a permanent
magnet disposed inside the sidewall. Permeable components are
disposed on the circular portion of the hub.
[0011] When the driven element inside the cooled part is also
disposed a magnet or a permeable component, the driven element is
driven by means of the magnetic attraction and mutual traction so
as to synchronously rotate along with the hub. Therefore, when the
blade wheel rotates, on the one hand, the heat absorbed by the
cooling part is rapidly dissipated, on the other hand, the power
required to rotate the driven element is supplied at the same time
so that the blade wheel is capable of dissipating heat and driving
power simultaneously, attaining the goal of the power integration
and resulting in a faster and better cooling effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0020] The invention relates to a blade wheel structure, which
includes a hub having a circular portion on the top end face
disposed magnets or permeable components. When the driven element
inside the cooled part is also disposed magnets or permeable
components, the driven element is driven by means of the magnetic
attraction and mutual traction so as to synchronously rotate along
with the hub. Hence, while the blade wheel is rotating, firstly,
the heat of the cooled part is dissipated by the air flow driven
the blades disposed on the outer periphery of the hub, secondly,
the magnets or the permeable components disposed on the top end
face of the hub synchronously drive and provide the power required
to run the driven part, achieving the dual effects of the heat
dissipation and the power driving.
[0021] Several preferred embodiments, together with figures, are
listed below as examples illustrative of the relevant positions of
the parts composing the present invention.
[0022] As shown in FIG. 1, the cooling fan 6 is composed of a frame
61, a stator 62 and a blade wheel 63, wherein the frame 61 has a
shaft tube base therein supported by a plurality of ribs, the shaft
tube base has the stator 62 disposed and fixed thereon, and the
blade wheel is disposed to corresponds to the stator 62.
[0023] Together with the reference to FIG. 2, the blade wheel
contains a hub 64. The hub 64 has a circular flat end face on the
topside. The bottom portion of the flat end face is connected with
a spindle 67 at the center. A sidewall is formed by extending
downwardly from the outer perimeter of the flat end face. A
plurality of blades 65 are disposed on the outer periphery of the
sidewall and a permanent magnet 66 is disposed inside the inner
periphery. The circular portion on the topside of the hub 64 is
disposed a permeable component 641. The permeable component 641 are
a magnet or a metal with permeable characteristics, and the
permeable component 641 and the hub 64 can be fastened by any one
of the sticking means, the engaging means and the inserting
means.
[0024] As shown in FIG. 2, the permeable component 641 includes
magnets having at least two different polarities and taking a shape
of a sector plate. The permeable component 641 is fixed on the hub
64 by the sticking means. Besides, the permeable component 641 can
be a single-piece annular magnet having the magnetic poles with at
least two polarities.
[0025] As shown in FIG. 3, the permeable component 642 is a
single-piece annular permeable metal. The hub has a plurality of
clips 643 disposed on circular portion of the topside of the hub 64
so as to fasten the permeable components 642 on the hub 64.
[0026] As shown in FIG. 4, the hub 64 has at least two positioning
slots 645 located on the circular portion of the topside of the hub
64. The positioning slot 645 allows the permeable component 644 to
be inserted in the positioning slot and fastened on the hub 64.
[0027] Moreover, FIG. 5 and FIG. 6 illustrate the preferred
embodiment of the heat sink applied in the present invention.
[0028] The heat sink 21 includes a central heat conducting body 22.
A plurality of cooling fins 23 extending outwardly from the
periphery on the central heat conducting body 22. The central heat
conducting body 22 has a through-hole penetrating one side thereof.
The opening of the through-hole is enclosed by a cover plate 24 so
as to form a fully-sealed hollow chamber 221. The chamber is filled
with a cooling liquid and is disposed an agitator 25 therein. The
agitator 25 has a permeable component 251 corresponding to a
permeable component 641 disposed thereon. The two permeable
components 251, 641 have the magnetic attraction and mutual
traction therebetween so that the agitator 25 can synchronously
rotate along with the hub 64.
[0029] During implementation, the heat sink 21 directly contacts
with the heating element to absorb the heat thereof. The cooling
fan 6 is disposed on the heat sink 21 to dissipate the heat
thereof. As such, when the blade wheel rotates, the blades on the
outer periphery of the hub 64 drive the airflow to dissipate the
heat of the cooling fins 23 on the heat sink 21. Meanwhile, the
permeable component 641 on the hub 64 pulls the agitator 25 to
provide the power required for the agitator 25 and the hub 64 to
synchronously rotate so as to agitate the cooling liquid filled in
the chamber 221, attaining the dual effects inclusive of heat
dissipation and power driving.
[0030] FIG. 7 and FIG. 8 illustrate the preferred embodiment of
water pump applied in the present invention.
[0031] The topside of the water pump 31 is covered by a cover plate
31 so as to enclose an inner space 311. The inner space 311 is
connected with an inlet tube 312 and an outlet tube 313
respectively. The water pump 31 has a plurality of cooling fins 33
extending from the outer periphery thereof, and an active gear 34
is housed in the inner space 311. The active gear 34 is disposed a
permeable component 341 corresponding to the permeable component
641 disposed on the hub so that the magnetic attraction and mutual
traction exist between the two permeable components, allowing to
synchronously rotate the active gear 34 and the hub 64.
[0032] During implementation, the water pump 31 drives the cooling
liquid to flow. The cooling fan 6 is disposed on the water pump 31
to assist the heat dissipation thereof. As a result, when the blade
wheel 63 rotates, the blades on the outer periphery of the hub 64
drive the airflow to dissipate the heat of the cooling fins on the
hub 64. Using the permeable components 641 on the hub 64 to draw
the active gear 34 and providing the active gear 34 the power for
synchronously rotating along with the hub 64 to drive the cooling
liquid for circulation, the dual effects for dissipating heat and
driving power are attained.
[0033] In sum, the blade wheel of the present invention,
attributable to the characteristics of the magnetic attraction and
the mutual traction, drives the driven element inside the cooled
part to synchronously rotate along with the hub. Hence, when the
blade wheel rotates, on the one hand, the blades disposed on the
outer periphery of the hub drive the airflow to dissipate the heat
of the cooled part, on the other hand, the magnets or permeable
components disposed on the top end face of the hub synchronously
draw the driven element and provide the required power to rotate
the driven element so as to enable the blade wheel to have dual
effects in dissipating heat and driving power, achieving the goal
of the power integration and the faster and better heat dissipation
effect. Therefore, the present invention not only has a novelty and
a progressiveness, but also has an industry utility.
[0034] While the invention has been described in terms of what is
presently considered to be the most practical and preferred
embodiments, it is to be understood that the invention needs not be
limited to the disclosed embodiments. 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.
