BACKGROUND OF THE INVENTION
[0002] With increasing development of computers and various
electronic products, people of the modern societies often spend lot
of time in using computers and various electronic products. In case
that the computer or the electronic product has been operated for a
long time, the heat generated by the computer or the electronic
product cannot be dissipated away quickly.
[0003] Generally, for most of the electronic products, thermal
greases or heat sinks are attached on the heat generation
components of the electronic products to absorb the heat from the
heat generation components and dissipate the heat away. As known,
the heat dissipating efficiency of using the thermal grease or the
heat sink is usually unsatisfied.
[0004] FIG. 1 schematically illustrates the architecture of a
conventional liquid-cooling heat dissipating module. As shown in
FIG. 1, the liquid-cooling heat dissipating module 6 comprises a

63. Every two of the water-cooling radiator 61, the water-cooling
head 62 and the water pump 63 are connected with each other through
a pipe 67. Consequently, the water-cooling radiator 61, the
water-cooling head 62 and the water pump 63 are in fluid
communication with each other. However, since the water-cooling
radiator 61, the water-cooling head 62 and the water pump 63 are
not fixed on each other, these components are dispersedly arranged.
Under this circumstance, the space utilization is usually
unsatisfied.
[0005] Therefore, the conventional liquid-cooling heat dissipating
module needs to be further improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0032] FIG. 2 is a schematic perspective view illustrating the
architecture of a liquid-cooling heat dissipating module according
to a first embodiment of the present invention. FIG. 3 is a
schematic cross-sectional view illustrating a water-cooling head
assembly and an external pump of the liquid-cooling heat
dissipating module according to the first embodiment of the present
invention. FIG. 4 is a schematic exploded view illustrating the
water-cooling head assembly and the external pump of the
liquid-cooling heat dissipating module according to the first
embodiment of the present invention. In this embodiment, the
liquid-cooling heat dissipating module 1 comprises a water-cooling
radiator 11, a water-cooling head assembly 12 and an external pump
13. The water-cooling radiator 11, the water-cooling head assembly
12 and the external pump 13 are in fluid communication with each
other to define a sealed circulating loop. Moreover, a fluidic
medium (not shown) is filled in the sealed circulating loop. As the
fluidic medium flows within the sealed circulating loop, heat
energy is transmitted from a higher temperature site to a lower
temperature site of the liquid-cooling heat dissipating module 1.
Consequently, the temperature at the higher temperature site is
effectively decreased.
[0033] In this context, the external pump 13 is a pump unit that is
independently and individually operated. The external pump 13
comprises a housing 130, a pump inlet 132, a pump outlet 133 and a
fluid pusher (not shown). A sealed space for accommodating the
fluidic medium is defined by the housing 130. The sealed space is a
second chamber 131. The second chamber 131 will be described
later.
[0034] The water-cooling head assembly 12 is attached on a heat
source 8 of an external object 9 (see FIG. 2). After the heat from
the heat source 8 is absorbed by the water-cooling head assembly
12, the heat is transferred to the water-cooling radiator 11
through the fluidic medium. Due to the heat exchange of the
water-cooling radiator 11, the temperature is decreased. Moreover,
the water-cooling head assembly 12 comprises a water-cooling head
121 and a bracket 122. The bracket 122 is contacted with the
water-cooling head 121. When the bracket 122 is fixed on the
external object 9 by screwing means, the water-cooling head 121 is
clamped between the bracket 122 and the object 9. In this
embodiment, the water-cooling head 121 has a flat bottom surface
1210. The flat bottom surface 1210 is contacted with the heat
source 8 of the object 9. By means of the large-area contact, the
heat exchange between the liquid-cooling heat dissipating module 1
and the heat source 8 of the object 9 is achieved quickly.
[0035] Please refer to FIGS. 2 and 3 again. The water-cooling head
121 comprises a first chamber 1211, a head inlet 1212 and a head
outlet 1213. The first chamber 1211, the head inlet 1212 and the
head outlet 1213 are in fluid communication with each other. The
water-cooling head 121 is connected with the external pump 13
through the head inlet 1212 in order to receive the fluidic medium
from the external pump 13. The water-cooling head 121 is connected
with the water-cooling radiator 11 through the head outlet 1213 in
order to transmit the fluidic medium to the water-cooling radiator
11.
[0036] Please refer to FIGS. 3 and 4 again. The external pump 13
further comprises a pump tube 134. The second chamber 131, the pump
inlet 132, the pump outlet 133 and the pump tube 134 are in fluid
communication with each other. The two ends of the pump tube 134
are connected with the pump outlet 133 and the head inlet 1212,
respectively. Consequently, the water-cooling head 121 and the
external pump 13 are in fluid communication with each other. The
fluidic medium flows in the direction from the external pump 13 to
the water-cooling head 121.
[0037] FIG. 5 is a schematic cross-sectional view illustrating the
water-cooling radiator of the liquid-cooling heat dissipating
module according to the first embodiment of the present invention.
Please refer to FIGS. 2 and 5. The water-cooling radiator 11
comprises a radiator inner channel 110, a radiator outlet tube 111
and a radiator inlet tube 112. The radiator inner channel 110, the
radiator outlet tube 111 and the radiator inlet tube 112 are in
fluid communication with each other. The head outlet 1213 of the
water-cooling head 121 is connected with the radiator inlet tube
112 of the water-cooling radiator 11. After the heated fluidic
medium having the higher temperature is outputted from the
water-cooling head 121, the fluidic medium is introduced into the
water-cooling radiator 11 through the radiator inlet tube 112. Due
to the heat exchange of the water-cooling radiator 11, the
temperature of the fluidic medium is decreased. Moreover, the
radiator outlet tube 111 is connected with the pump inlet 132 of
the external pump 13. After the temperature of the fluidic medium
is decreased by the water-cooling radiator 11, the fluidic medium
is introduced into the external pump 13 through the water-cooling
radiator 11. Then, the fluidic medium in the external pump 13 is
pressurized and pushed to the water-cooling head 121. Consequently,
the fluidic medium can circularly flows within the liquid-cooling
heat dissipating module 1.
[0038] Please refer to FIG. 5 again. The radiator inner channel 110
comprises a left communication channel part 110a, a right
communication channel part 110b, an upper chamber 110c and a lower
chamber 110d. The upper chamber 110c and the lower chamber 110d are
separated from each other. The radiator inlet tube 112 is in
communication with the lower chamber 110d. The radiator outlet tube
111 is in communication with the upper chamber 110c. The two ends
of the left communication channel part 110a are connected with the
upper chamber 110c and the lower chamber 110d, respectively. The
two ends of the right communication channel part 110b are connected
with the upper chamber 110c and the lower chamber 110d,
respectively. After the fluidic medium is introduced into the lower
chamber 110d through the radiator inlet tube 112, the fluidic
medium separately flows toward the left side and the right side to
the upper chamber 110c through the left communication channel part
110a and the right communication channel part 110b. The flowing
directions of the fluidic medium are indicated by the arrows as
shown in FIG. 5. After the fluidic medium is outputted from the
upper chamber 110c, the fluidic medium is transmitted to the
external pump 13 though the radiator outlet tube 111.
[0039] As shown in FIG. 2, the liquid-cooling heat dissipating
module 1 further comprises two fan modules 19. The two fan modules
19 are arranged beside the left communication channel part 110a and
the right communication channel part 110b, respectively. The two
fan modules 19 are used for creating airflow and guiding the
airflow toward the left communication channel part 110a and the
right communication channel part 110b, respectively. By the
airflow, the heat of the fluidic medium in the water-cooling
radiator 11 is quickly dissipated to the surroundings.
Consequently, the heat dissipating efficiency is enhanced.
[0040] As mentioned above, the fluidic medium flows within the
sealed circulating loop. After the fluidic medium flows through the
first chamber 1211, the head outlet 1213, the radiator inlet tube
112, the lower chamber 110d, the communication channel parts
110a/110b, the upper chamber 110c, the radiator outlet tube 111,
the pump inlet 132, the second chamber 131, the pump outlet 133,
the pump tube 134 and the head inlet 1212 sequentially, the fluidic
medium returns back to the first chamber 1211.
[0041] Please refer to FIGS. 2, 3 and 4. The water-cooling head
assembly 12 further comprises a position-limiting element 123.
After the position-limiting element 123 is connected with the
bracket 122, a clamping space is defined by the position-limiting
element 123 and the bracket 122 collaboratively, and the external
pump 13 is accommodated within the clamping space. That is, the
external pump 13 is clamped and positioned by the position-limiting
element 123 and the bracket 122. By the position-limiting element
123, the two independent components (i.e., the external pump 13 and
the water-cooling head assembly 12) are contacted with each other.
Consequently, the volume (i.e., the occupied space) of the
liquid-cooling heat dissipating module 1 is effectively
reduced.
[0042] Moreover, two bent supporting structures 1220 are extended
from the bracket 122 in the direction away from the first chamber
1211. The position-limiting element 123 comprises a middle pressing
part 1230 and two coupling parts 1231. The two coupling parts 1231
are respectively located at two ends of the middle pressing part
1230. The external pump 13 is covered and pressed by the middle
pressing part 1230 of the position-limiting element 123. Moreover,
the two coupling parts 1231 of the position-limiting element 123
are fixed on the two bent supporting structures 1220 by screwing
means. Consequently, the external pump 13 is positioned on the
bracket 122 through the position-limiting element 123.
[0043] Moreover, the bracket 122 is an I-shaped bracket. The
bracket 122 comprises a middle supporting segment 1221 and two
lateral supporting segments 1222. The two lateral supporting
segments 1222 are respectively connected to the two ends of the
middle supporting segment 1221. The water-cooling head 121 further
comprises a concave structure 1214. The middle supporting segment
1221 is received within the concave structure 1214. The two lateral
supporting segments 1222 are extended beyond the range of the
water-cooling head 121. Each of the two lateral supporting segments
1222 comprises at least one fastening hole 1223. In this
embodiment, each of the two lateral supporting segments 1222
comprises two fastening holes 1223. After fastening elements 1224
are penetrated through the corresponding fastening holes 1223 and
tightened in the external object 9, the bracket 122 is fixed on the
external object 9 by screwing means. It is noted that the way of
fixing the associated components is not restricted to the screwing
means. In some other embodiments, the associated components are
connected with each other by welding means, adhering means or any
other appropriate connecting means.
[0044] In an embodiment, the external pump 13 is a cylindrical
pump. The pump inlet 132 is located at a bottom side of the
cylindrical pump, and the pump outlet 133 is located at a lateral
side of the cylindrical pump.
[0045] FIG. 6 is a schematic perspective view illustrating the
architecture of a liquid-cooling heat dissipating module according
to a second embodiment of the present invention. FIG. 7 is a
schematic cross-sectional view illustrating a water-cooling head
assembly and an external pump of the liquid-cooling heat
dissipating module according to the second embodiment of the
present invention. FIG. 8 is a schematic exploded view illustrating
the water-cooling head assembly and the external pump of the
liquid-cooling heat dissipating module according to the second
embodiment of the present invention. The liquid-cooling heat
dissipating module 2 of this embodiment is similar to the
liquid-cooling heat dissipating module of the first embodiment. In
this embodiment, the liquid-cooling heat dissipating module 2
comprises a water-cooling radiator 21, a water-cooling head
assembly 22 and an external pump 23. The water-cooling radiator 21,
the water-cooling head assembly 22 and the external pump 23 are in
fluid communication with each other to define a sealed circulating
loop. Moreover, a fluidic medium (not shown) is filled in the
sealed circulating loop. As the fluidic medium flows within the
sealed circulating loop, heat energy is transmitted from a higher
temperature site to a lower temperature site of the liquid-cooling
heat dissipating module 2. Consequently, the temperature at the
higher temperature site is effectively decreased.
[0046] Similarly, water-cooling head assembly 22 is attached on an
external object 9'. After the heat from the object 9' is absorbed
by the water-cooling head assembly 22, the heat is transferred to
the water-cooling radiator 21 through the fluidic medium and
dissipated away by the water-cooling radiator 21. Moreover, the
water-cooling head assembly 22 comprises a water-cooling head 221
and a bracket 222. The bracket 222 is contacted with the
water-cooling head 221. The bracket 222 is fixed on the external
object 9' by screwing means.
[0047] In comparison with the first embodiment, the external pump
23 of the liquid-cooling heat dissipating module 2 of this
embodiment is distinguished. Similarly, the external pump 23
comprises a second chamber (not shown), a pump inlet 232 and a pump
outlet 233. Moreover, the external pump 23 further comprises an
adapter part 230. The external pump 23 is directly coupled with and
fixed on the water-cooling head 221 through the adapter part 230.
In this embodiment, the external pump 23 is directly coupled with
the water-cooling head 221 through the adapter part 230 only.
Moreover, the external pump 23 is positioned and fixed through the
adapter part 230 and the water-cooling head 221. Moreover, the
external pump 23 of this embodiment is not contacted with the
bracket 222. In an embodiment, the external pump 23 is further
fixed on the external object 9' or another object with the
assistance of a coupling element 235.
[0048] In this embodiment, the adapter part 230 is an adapter ring.
The two ends 230a and 230b of the adapter ring are respectively
directly coupled with the pump outlet 233 and the head inlet 221a.
In an embodiment, the head inlet 221a is made of a first material
(e.g., a plastic material), and the pump outlet 233 is made of a
second material (e.g., a metallic material). Under this
circumstance, the two ends 230a and 230b of the adapter ring 230
are made of the plastic material and the metallic material,
respectively. Since the components of the identical material are
directly coupled with each other, the tightness at the joint is
enhanced. Preferably but not exclusively, the adapter ring 230 is
made of a hard material.
[0049] As mentioned above, the external pump 23 is contacted with
the water-cooling head 221. Consequently, the layout space is
saved. Moreover, since the longer pump tube of the first embodiment
is not used in this embodiment, the pressure drop of the fluidic
medium is effectively decreased. Moreover, the two independent
components (i.e., the external pump 23 and the water-cooling head
assembly 22) are contacted with each other. That is, when the
external pump 23 and the water-cooling head 221 are directly
coupled with each other, the external pump 23 and the water-cooling
head assembly 22 are combined together. Consequently, the overall
volume (i.e., the occupied space) of the liquid-cooling heat
dissipating module 2 is effectively reduced.
[0050] In another embodiment, the head inlet 221a, the adapter part
230 and the pump outlet 233 are made of the same material.
Consequently, the tightness at the joint is enhanced. In a further
embodiment, the adapter part 230 is an extension part of the head
inlet 221a and directly coupled with the pump outlet 233, or the
adapter part 230 is an extension part of the pump outlet 233 and
directly coupled with the head inlet 221a.
[0051] In this embodiment, the bracket 222 is also an I-shaped
bracket. The bracket 222 comprises a middle supporting segment 2221
and two lateral supporting segments 2222. The two lateral
supporting segments 2222 are respectively connected to the two ends
of the middle supporting segment 2221. The water-cooling head 221
further comprises a concave structure 2214. The middle supporting
segment 2221 is received within the concave structure 2214. The two
lateral supporting segments 2222 are extended beyond the range of
the water-cooling head 221. Each of the two lateral supporting
segments 2222 comprises at least one fastening hole 2223. In this
embodiment, each of the two lateral supporting segments 2222
comprises two fastening holes 2223. After fastening elements 2224
are penetrated through the corresponding fastening holes 2223 and
tightened in the external object 9', the bracket 222 is fixed on
the external object 9' by screwing means. It is noted that the way
of fixing the associated components is not restricted to the
screwing means. In some other embodiments, the associated
components are connected with each other by welding means, adhering
means or any other appropriate connecting means.
[0052] FIG. 9 is a schematic exploded view illustrating a
water-cooling head assembly and an external pump of a
liquid-cooling heat dissipating module according to a third
embodiment of the present invention. The liquid-cooling heat
dissipating module 3 of this embodiment is similar to the
liquid-cooling heat dissipating module of the first embodiment. In
this embodiment, the liquid-cooling heat dissipating module 3
comprises a water-cooling radiator 31, a water-cooling head
assembly 32 and an external pump 33. The water-cooling radiator 31,
the water-cooling head assembly 32 and the external pump 33 are in
fluid communication with each other to define a sealed circulating
loop. Moreover, a fluidic medium (not shown) is filled in the
sealed circulating loop. Similarly, the water-cooling head assembly
32 of this embodiment comprises a water-cooling head 321 and a
bracket 322. The bracket 322 is contacted with the water-cooling
head 321. The bracket 322 is fixed on an external object by
screwing means.
[0053] In this embodiment, the water-cooling radiator 31 and the
water-cooling head assembly 32 are assembled-type components, but
are not the one-piece components. That is, even if the
water-cooling radiator 31 and the water-cooling head assembly 32
are not assembled with each other, the water-cooling radiator 31
and the water-cooling head assembly 32 have their own
functions.
[0054] From the above descriptions, the present invention provides
the liquid-cooling heat dissipating module. The external pump and
the water-cooling head assembly of the liquid-cooling heat
dissipating module are contacted and assembled with each other.
Consequently, the layout space is saved, and more space is provided
to accommodate other components. Moreover, since the external pump
is directly coupled with the water-cooling head assembly, the
pressure drop of the fluidic medium is decreased.
[0055] 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 modifications and similar structures.
