Description
FIELD OF THE INVENTION
[0001] The present invention relates to a water cooling module, and
more particularly, to a water cooling module that avoids the
problems of oxidized and leaked pipes and provides prolonged
service life.
BACKGROUND OF THE INVENTION
[0002] Recently, water cooling modules have been widely used to
dissipate heat produced by high-power heat sources. Since the water
cooling modules provide relatively good heat dissipation
efficiency, they are not only used to remove heat from desktop
personal computers, but also widely applied to industrial computers
and server system chasses.
[0003] A water cooling module mainly includes a water block, a pump
and a water container; and these units are serially connected to
one another via pipes, such that a working fluid for circulating
through the water cooling module can successfully achieve the
purpose of cooling one or more heat sources. In most cases, the
pipes used to guide the working fluid are rubber pipes to provide
required flexibility in use. The rubber pipes tend to oxidize or
leak when they have been used over a long period of time, which
will cause damage of cooling apparatus.
[0004] Metal pipes are sometimes used to replace the rubber pipes.
While the metal pipes have longer service life and are not easily
oxidized or broken compared to the rubber pipes, they must be
connected to the water block, the pump and the water container by
welding. Therefore, there are limits to the materials and the
welding methods that can be adopted for the metal pipes used in the
water cooling modules.
[0005] It is therefore very important to overcome the problem of
oxidized and leaked pipes in the conventional water cooling
modules.
SUMMARY OF THE INVENTION
[0006] A primary object of the present invention is to provide a
water cooling module that avoids the problem of oxidized and leaked
pipes found in the prior art water cooling modules.
[0007] To achieve the above and other objects, the water cooling
module provided according to the present invention includes a
flow-guiding main body and a pump set.
[0008] The flow-guiding main body includes a first inlet, a first
outlet and a flow-guiding passage set. The flow-guiding passage set
includes a plurality of flow-guiding passages, and the first inlet
and the first outlet are respectively communicable with one of the
flow-guiding passages.
[0009] The pump set includes a first pump having a first water
inlet and a first water outlet, and a second pump having a second
water inlet and a second water outlet. The first water inlet and
the first water outlet are respectively communicable with one of
the flow-guiding passages; and the second water inlet and the
second water outlet are also respectively communicable with one of
the flow-guiding passages.
[0010] By using the flow-guiding passage set in the flow-guiding
main body to replace the conventional rubber or metal pipes used to
connect to the pumps, the water cooling module according to the
present invention can have a further reduced volume and avoids the
problem of easily oxidized and leaked pipes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0024] The present invention will now be described with some
preferred embodiments thereof and by referring to the accompanying
drawings. For the purpose of easy to understand, elements that are
the same in the preferred embodiments are denoted by the same
reference numerals.
[0025] Please refer to FIGS. 1 and 2 that show an exploded
perspective view and an assembled, partially sectioned perspective
view, respectively, of a water cooling module 1 according to a
first embodiment of the present invention. As shown, the water
cooling module 1 in the first embodiment includes a flow-guiding
main body 11 and a pump set 12.
[0026] The flow-guiding main body 11 is composed of an upper part
11a and a lower part lib, which are correspondingly closed to each
other to together define a flow-guiding passage set 113 between
them. More specifically, the flow-guiding passage set 113 is formed
on a top side of the lower part 11b of the flow-guiding main body
11. On the flow-guiding main body 11, there are also provided a
first inlet 111 and a first outlet 112. The flow-guiding passage
set 113 includes a plurality of flow-guiding passages; and the
first inlet 111 and the first outlet 112 are respectively
communicable with one of the flow-guiding passages.
[0027] The pump set 12 includes a first pump 121 and a second pump
122. The first pump 121 has a first water inlet 1211 and a first
water outlet 1212; and the second pump 122 has a second water inlet
1221 and a second water outlet 1222. The first water inlet 1211 and
the first water outlet 1212 are respectively communicable with one
of the flow-guiding passages. Similarly, the second water inlet
1221 and the second water outlet 1222 are respectively communicable
with one of the flow-guiding passages.
[0028] The flow-guiding passage set 113 includes a first
flow-guiding passage 1131, a second flow-guiding passage 1132, and
a third flow-guiding passage 1133. The first flow-guiding passage
1131 is connected at two ends to the first inlet 111 of the
flow-guiding main body 11 and the first water inlet 1211 of the
first pump 121; the second flow-guiding passage 1132 is connected
at two ends to the first water outlet 1212 of the first pump 121
and the second water inlet 1221 of the second pump 122; and the
third flow-guiding passage 1133 is connected at two ends to the
second water outlet 1222 of the second pump 122 and the first
outlet 112 of the flow-guiding main body 11.
[0029] A working fluid 2, which can be water according to the
present invention, enters the first flow-guiding passage 1131 via
the first inlet 111 of the flow-guiding main body 11. The working
fluid 2 is then guided by the first flow-guiding passage 1131 into
the first pump 121 via the first water inlet 1211, and the pressure
of the working fluid 2 is boosted in the first pump 121. Then, the
working fluid 2 flows out of the first pump 121 via the first water
outlet 1212 into the second flow-guiding passage 1132.
[0030] The working fluid 2 is further guided by the second
flow-guiding passage 1132 into the second pump 122 via the second
water inlet 1221. In the second pump 122, the pressure of the
working fluid 2 is boosted for a second time. Then, the working
fluid 2 flows through the second water outlet 1222 of the second
pump 122 into the third flow-guiding passage 1133 that communicates
with the second water outlet 1222. Finally, the working fluid 2 is
guided by the third flow-guiding passage 1133 to flow out of the
flow-guiding main body 11 via the first outlet 112. In the first
embodiment, the first pump 121 is serially connected to the second
pump 122 via the flow-guiding main body 11 to enable serial water
flow between them and achieve a flow pressure boosting effect
through such serial connection.
[0031] Please refer to FIGS. 3 and 4, which are exploded top and
bottom perspective views, respectively, of a water cooling module 1
according to a second embodiment of the present invention. As
shown, the second embodiment is generally structurally similar to
the first embodiment but the flow-guiding main body 11 thereof
further includes a cavity portion 114, a plate member 115 and a
second outlet 116. The cavity portion 114 is formed at a bottom
side of the lower part 11b of the flow-guiding main body 11 to face
away from the top side having the flow-guiding passage set 113
formed thereon. That is, the cavity portion 114 is downward opened.
The cavity portion 114 is communicable with the first and the
second outlet 112, 116; and the plate member 115 correspondingly
closes the cavity portion 114. The plate member 115 has a plurality
of radiating fins 117 formed on one side facing toward the cavity
portion 114. Another side of the plate member 115 facing away from
the radiating fins 117 is a heat-absorbing side 1151 for contacting
with at least one heat source 3 to absorb heat produced by the heat
source 3 and transfer the absorbed heat to the radiating fins 117.
The working fluid 2 enters the cavity portion 114 via the first
outlet 112 and then flows through the radiating fins 117 to finally
flow out of the cavity portion 114 via the second outlet 116.
Meanwhile, heat is carried away from the radiating fins 117 by the
working fluid 2.
[0032] Please refer to FIGS. 5 and 6, which show a partially
exploded top perspective view and an assembled, partially sectioned
perspective view, respectively, of a water cooling module 1
according to a third embodiment of the present invention. As shown,
the third embodiment is generally structurally similar to the
second embodiment but further includes a water cooling radiator 4.
The water cooling radiator 4 includes a first water-receiving
chamber 41, a first connecting portion 42, and a second connecting
portion 43. The first water-receiving chamber 41 internally defines
a first water-receiving space 411 communicable with the first and
the second connecting portion 42, 43. The first and the second
connecting portion 42, 43 are configured for connecting to the
first inlet 111 and the second outlet 116, respectively. The water
cooling radiator 4 is mainly used to cool the working fluid 2 that
has absorbed heat. More specifically, the heat-carrying working
fluid 2 flows out of the flow-guiding main body 11 via the second
outlet 116 and then flows into the first water-receiving space 411
of the first water-receiving chamber 41 via the second connecting
portion 43 that is connected to the second outlet 116. The
heat-carrying working fluid 2 is cooled in the water cooling
radiator 4 and then flows out of the first water-receiving space
411 via the first connecting portion 42 into the flow-guiding main
body 11 via the first inlet 111, which is connected to the first
connecting portion 42, to start another cycle of cooling
circulation through the water cooling module 1.
[0033] FIG. 7 is a partially exploded top perspective view of a
water cooling module 1 according to a fourth embodiment of the
present invention. As shown, the fourth embodiment is generally
structurally similar to the third embodiment but includes a
plurality of water cooling radiators 4, which are sequentially
stacked from top to bottom. In FIG. 7, there are shown two
vertically stacked water cooling radiators 4. The fourth embodiment
further includes a plurality of radiating fin assemblies 5, such
that each of the water cooling radiators 4 is sandwiched between
two of the radiating fin assemblies 5. In the fourth embodiment,
the flow-guiding main body 11 is further provided with a second
inlet 119 and a third outlet 118, which are located at the same
side as the first inlet 111 and the second outlet 116. The first
water-receiving spaces 411 of the water cooling radiators 4 are
communicable with one another; the first and second connecting
portions 42, 43 of one of the water cooling radiators 4 are
connected to the first inlet 111 and the second outlet 116,
respectively, while the first and the second connecting portions
42, 43 of the other water cooling radiator 4 are connected to the
second inlet 119 and the third outlet 118, respectively. The water
cooling radiators 4 are mainly used to cool the working fluid 2
that has absorbed heat.
[0034] According to the fourth embodiment, the water cooling
radiators 4 can be three or more (not shown) in number without
being particularly limited to any specific quantity.
[0035] FIG. 8 is an exploded perspective view of a water cooling
module 1 according to a fifth embodiment of the present invention.
As shown, in the fifth embodiment, the pump set 12 of the water
cooling module 1 includes a plurality of first pumps 121
sequentially stacked from top to bottom and a plurality of second
pumps 122 sequentially stacked from top to bottom. Since the first
water inlets and outlets 1211, 1212 of the first pumps 121 are
arranged in the same manner as the first water inlet and outlet
1211, 1212 in the first embodiment, they are not repeatedly
described. Similarly, since the second water inlets and outlets
1221, 1222 of the second pumps 122 are arranged in the same manner
as the second water inlet and outlet 1221, 1222 in the first
embodiment, they are not repeatedly described.
[0036] In the fifth embodiment, the first pumps 121 are parallelly
connected to the flow-guiding main body 11 and the second pumps 122
are also parallelly connected to the flow-guiding main body 11,
such that the first pumps 121 are correspondingly serially
connected to the second pumps 122 via the flow-guiding main body
11.
[0037] Please refer to FIGS. 9a and 9b, which are exploded top and
bottom perspective views, respectively, of a water block 5 included
in a water cooling module 1 according to a sixth embodiment of the
present invention, and to FIG. 10, which is an exploded top
perspective view of the water cooling module 1 according to the
sixth embodiment of the present invention. As shown, the sixth
embodiment is generally structurally similar to the first
embodiment but further includes a water block 5 serially connected
to the flow-guiding main body 11. The water block 5 includes a
heat-exchange water-receiving space 51, a heat-exchange plate
member 52, and a water inlet 53 and a water outlet 54. The
heat-exchange water-receiving space 51 has one open side and is
communicable with the water inlet 53 and the water outlet 54.
[0038] The heat-exchange plate member 52 correspondingly closes the
open side of the heat-exchange water-receiving space 51. One side
of the heat-exchange plate member 52 that faces toward the
heat-exchange water-receiving space 51 is provided with a plurality
of radiating fins 55, and another side of the heat-exchange plate
member 52 that faces away from the radiating fins 55 is a
heat-absorbing side 551 for contacting with at least one heat
source (not shown). In the sixth embodiment, the water block 5 is
serially connected to the flow-guiding main body 11, such that the
water outlet 54 of the water block 5 is communicable with the first
inlet 111 of the flow-guiding main body 11 and the water inlet 53
of the water block 5 is communicable with the first outlet 112 of
the flow-guiding main body 11.
[0039] Please refer to FIG. 11, which is an assembled, partially
sectioned top view of a water cooling module 1 according to a
seventh embodiment of the present invention. As shown, the seventh
embodiment is generally structurally similar to the first
embodiment but the flow-guiding main body 11 thereof has a
flow-guiding passage set 113 including only a first flow-guiding
passage 1131 and a second flow-guiding passage 1132. The first
flow-guiding passage 1131 is connected at one end to the first
inlet 111 of the flow-guiding main body 11 and at another end to
the first water inlet 1211 of the first pump 121 and the second
water inlet 1221 of the second pump 122. Similarly, the second
flow-guiding passage 1132 is connected at one end to the first
outlet 112 of the flow-guiding main body 11 and at another end to
the first water outlet 1212 of the first pump 121 and the second
water outlet 1222 of the second pump 122.
[0040] In the seventh embodiment, a check valve 6 is connected to
the first water outlet 1212 of the first pump 121, and another
check valve 6 is connected to the second water outlet 1222 of the
second pump 122. When the working fluid 2 has flowed into the
flow-guiding main body 11 via the first inlet 111, the working
fluid 2 is firstly guided by the first flow-guiding passage 1131
into the first pump 121 via the first water inlet 1211 and into the
second pump 122 via the second water inlet 1221 to enable an
increased outgoing water quantity from the first and second pumps
121, 122. Then, the working fluid 2 leaves the first and the second
pump 121, 122 via the first water outlet 1212 and the second water
outlet 1222, respectively, into the second flow-guiding passage
1132. Finally, the working fluid 2 leaves the flow-guiding main
body 11 via the first outlet 112. In the seventh embodiment, with
the specific configuration of the flow-guiding passage set 113 of
the flow-guiding main body 11, the first pump 121 is parallelly
connected to the second pump 122 to thereby enable an increased
outgoing water quantity. In the event any of the first and the
second pump 121, 122 is failed, the check valve 6 connected to the
failed pump can prevent the working fluid 2 in the second
flow-guiding passage 1132 from flowing back into the failed pump
121 or 122.
[0041] According to any of the above-described embodiments of the
present invention, the number of sets of the first and second
pumps, either serially or parallelly connected to one another, can
be increased without being particularly limited. Alternatively,
some sets of serially connected first and second pumps can be
provided along with some sets of parallelly connected first and
second pumps.
[0042] With the water cooling module of the present invention, it
is able to avoid the problems in the conventional water cooling
modules, including the use of rubber pipes that tend to oxidize
after having been used over a long period of time and the use of
metal pipes that must be made of a suitable metal material to
enable forming of good welded joints. Therefore, the water cooling
module of the present invention has the advantages of providing
prolonged service life and having a further reduced overall volume
to enable easy application thereof.
[0043] The present invention has been described with some preferred
embodiments thereof and it is understood that many changes and
modifications in the described embodiments can be carried out
without departing from the scope and the spirit of the invention
that is intended to be limited only by the appended claims.
