The present invention relates to a water-cooling radiator assembly with internal horizontal partition members and fluid disturbing members, and more particularly, to a water-cooling radiator assembly with internal horizontal partition members and fluid disturbing members that provides upgraded heat dissipation effect.
Many electronic elements in a computer will produce a large quantity of heat when the computer operates. Hence, a good heat dissipation system is a key factor that determines the effectiveness and reliability of a computer. In a computer, the workload of the central processing unit (CPU) and the graphic processing unit (GPU) is higher than any other heat-producing elements in the computer, and accordingly, solutions for dissipating heat produced by the CPU and the GPU are no doubt very important. Particularly, the currently available computer games all include highly exquisite images that require computer-aided design (CAD) software with increasingly enhanced functions to achieve. However, the operation of such CAD software will render the CPU and the GPU into a heavy workload state to produce a huge quantity of heat. Heat accumulated in the computer would result in lowered performance of the CPU and GPU, or, in some worse condition, even result in damages or largely shortened service life of the CPU and GPU.
Different water cooling systems are available in the market for lowering the working temperature of the heat-producing electronic elements. A conventional water cooling system generally includes a water-cooling radiator 1 fluid-communicably connected to a pump 1a and a water block 1b via two water pipes. The water block 1b is in contact with a heat-producing element, such as a CPU. The pump 1a drives a cooling liquid, i.e. a working fluid such as water, from the water block 1b to flow into the water-cooling radiator 1, so that heat absorbed and carried by the working fluid is transferred to and dissipated from the water-cooling radiator 1 into ambient air. The pump 1a drives the cooling liquid to continuously circulate between the water-cooling radiator 1 and the water block 1b to enable quick removal of heat from the heat-producing electronic element.
The working fluid flowed into the first side water tank 13 via the water inlet 131 quickly and straightly flows through the straight flat pipes 12 to the second side water tank 13, and then quickly flows back to the first side water tank 13 via the straight flat pipes 12 and leaves the water-cooling radiator structure 1 via the water outlet 132. Therefore, the time period from the entering to the leaving of the heat-carrying working fluid into and from the water-cooling radiator structure 1 is very short and there is not sufficient time for the heated working fluid to exchange heat with the water-cooling radiator structure 1. As a result, the conventional water-cooling radiator structure 1 could not effectively remove the heat from the working fluid flowing therethrough and has the problem of poor heat dissipation efficiency. In addition, the conventional water-cooling radiator structure 1 is an integral structure, which is not adjustable or changeable according to the internal space of an electronic device that uses the water-cooling radiator structure 1. Therefore, to use the water-cooling radiator structure 1 inside an electronic device, the electronic device must have an independent internal space sufficient for installing the water-cooling radiator structure 1.
A primary object of the present invention is to provide a water-cooling radiator assembly that has internal horizontal partition members and fluid disturbing members to provide enhanced heat removal performance.
Another object of the present invention is to provide a water-cooling radiator assembly with internal horizontal partition members and fluid disturbing members, according to which two or more liquid-receiving plates are superposed while vertically spaced from one another and each of the liquid-receiving plates is internally divided by a partition member into two independent liquid chambers, and at least one of the two independent liquid chambers is internally provided with a flow disturbing member that provides structural supporting and flow disturbing effects, so that the flow time of a working liquid flowing through the liquid chambers is increased to effectively upgrade the heat exchange efficiency of the water-cooling radiator assembly.
A further object of the present invention is to provide a water-cooling radiator assembly with internal horizontal partition members and fluid disturbing members, according to which a working liquid can flow between a first and a second liquid-receiving plate via a first, a second and a third communicating pipe, and the first and second liquid-receiving plates are respectively internally divided by a partition member into two independent liquid chambers, such that a part of the working liquid that is in one of the two independent liquid chambers of each liquid-receiving plate and has been cooled can exchange heat with another part of the working liquid that is in the other liquid chamber of the same liquid-receiving plate and still carries heat with it.
A still further object of the present invention is to provide a water-cooling radiator assembly with internal horizontal partition members and fluid disturbing members, according to which different numbers of liquid-receiving plates can be included and different numbers of communicating pipes can be provided at different positions between the liquid-receiving plates to communicate the liquid-receiving plates with one another; and the numbers and the positions of the liquid-receiving plates and the communicating pipes can be actively adjusted according to an internal space available in an electronic device, in which the water-cooling radiator assembly is to be mounted.
A still further object of the present invention is to provide a water-cooling radiator assembly with internal horizontal partition members and fluid disturbing members, according to which two or more liquid-receiving plates are included, and any or all of the liquid-receiving plates can be made of a titanium material that has high metal strength, low weight and good heat transfer efficiency and is corrosion resistant to enable effectively upgraded heat transfer effect and reduced overall weight of the water-cooling radiator assembly.
To achieve the above and other objects, the water-cooling radiator assembly with internal horizontal partition members and fluid disturbing members provided according to the present invention includes a liquid-receiving plate unit, a first flow disturbing member and a communicating pipe unit. The liquid-receiving plate unit includes a first and a second liquid-receiving plate. The first liquid-receiving plate has at least one liquid inlet provided thereon and a first partition member provided therein to divide an inner space of the first liquid-receiving plate into a first liquid chamber and a second liquid chamber; and the second liquid chamber is communicable with the at least one liquid inlet to allow a working liquid to flow into the second liquid chamber via the at least one liquid inlet. The second liquid-receiving plate has at least one liquid outlet provided thereon and a second partition member provided therein to divide an inner space of the second liquid-receiving plate into a third liquid chamber and a fourth liquid chamber; and the third liquid chamber is communicable with the at least one liquid outlet. The first flow disturbing member can be selectively arranged in any one of the first, the second, the third and the fourth liquid chamber. The communicating pipe unit includes a first, a second and a third communicating pipe. The first communicating pipe communicates the second liquid chamber with the fourth liquid chamber, the second communicating pipe communicates the fourth liquid chamber with the first liquid chamber, and the third communicating pipe communicates the first liquid chamber with the third liquid chamber. With the above arrangements, the flow time of the working liquid in the liquid chambers of the liquid-receiving plates can be increased, enabling the water-cooling radiator assembly of the present invention to have improved heat removal performance.

In the illustrated first embodiment, the working liquid 4 is a ketone liquid. However, the working liquid 4 is not limited to the ketone liquid but can be any other liquid that provides heat dissipation effect, such pure water, inorganic compounds, alcohols, liquid metals, coolants and organic compounds.
The second liquid-receiving plate 202 is disposed above and spaced from the first liquid-receiving plate 201. The second liquid-receiving plate 202 includes a second top plate member 2021 and a second bottom plate member 2022 closed and connected to each other, at least one liquid outlet 2027, a second opening 2025a and a second partition member 2023. The second partition member 2023 is arranged in the second liquid-receiving plate 202 between the second top plate member 2021 and the second bottom plate member 2022, so as to divide an inner space of the second liquid-receiving plate 202 into a third liquid chamber 2024a and a fourth liquid chamber 2024b. The third liquid chamber 2024a is communicable with the at least one liquid outlet 2027. The fourth liquid chamber 2024b is communicable with the second opening 2025a, which is formed on and penetrates the second bottom plate member 2022. The second partition member 2023 is not provided on an upper and a lower side thereof with any flow passage. In the illustrated first embodiment, the fourth liquid chamber 2024b is formed between the second bottom plate member 2022 and the second partition member 2023 while the third liquid chamber 2024a is formed between the second top plate member 2021 and the second partition member 2023. In other words, with the second partition member 2023 provided in the second liquid-receiving plate 202, the fourth liquid chamber 2024b and the third liquid chamber 2024a form two independent chambers in the second liquid-receiving plate 202 and are not directly communicable with each other.
In the illustrated first embodiment, there is shown only one liquid outlet 2027 arranged at one lateral side of the second liquid-receiving plate 202 and communicating with the third liquid chamber 2024a. In addition to the first communicating pipe 271, the communicating pipe unit 27 further includes a second and a third communicating pipe 272, 273. The first, second and third communicating pipes 271, 272, 273 can be made of gold, silver, copper, iron, titanium, aluminum or stainless steel, or any alloy of these metal materials. In the first embodiment, the first, second and third communicating pipes 271, 272, 273 are located between the first and the second liquid-receiving plate 201, 202 of the liquid-receiving plate unit 20. The first communicating pipe 271 has an end extended through the first opening 2015a and the first hole 20131 into the second liquid chamber 2014b and another end communicably connected to the second opening 2025a, such that the first communicating pipe 271 communicates the second liquid chamber 2014b with the fourth liquid chamber 2024b via the first opening 2015a and the second opening 2025a. The first communicating pipe 271 has an outer wall surface in tight contact with and connected to the first opening 2015a and the first hole 20131 by means of laser beam welding, welding or leakproof gasket, so as to prevent leakage of the working liquid 4 from the first and the second liquid chamber 2014a, 2014b. It is noted that, in the illustrated first embodiment, the liquid-receiving plates included in the liquid-receiving plate unit 20 are not limited to two in number, and the communicating pipes included in the communicating pipe unit 27 are not limited to three in number. In practical implementation of the present invention, the number of the liquid-receiving plates can be increased according to actual need in heat dissipation. For example, three or four or more liquid-receiving plates can be overlapped while vertically spaced from one another. Similarly, the number of the communicating pipes provided between any two mutually vertically spaced liquid-receiving plates can be increased according to actual need in heat dissipation. For example, five or six communicating pipes can be provided.
The first liquid-receiving plate 201 further includes a third opening 2015b and a fourth opening 2015c, which penetrate the first top plate member 2011. The second communicating pipe 272 has an end communicably connected to the fourth opening 2015c while the third communicating pipe 273 has an end communicably connected to the third opening 2015b. Therefore, the second and the third communicating pipe 272, 273 are communicable with the first liquid chamber 2014a. The second liquid-receiving plate 202 further includes a fifth opening 2025b and a sixth opening 2025c, which penetrate the second bottom plate member 2022. The second communicating pipe 272 has another end communicably connected to the sixth opening 2025c, so that the second communicating pipe 272 communicates the first liquid chamber 2014a with the fourth liquid chamber 2024b. The second partition member 2023 is provided with a second hole 20231, which penetrates the second partition member 2023 and is located corresponding to the fifth opening 2025b to communicate the fifth opening 2025b with the third liquid chamber 2024a. The third communicating pipe 273 has another end extended through the fifth opening 2025b and the second hole 20231 into the third liquid chamber 2024a, so as to communicate the first liquid chamber 2014a with the third liquid chamber 2024a. Similarly, the third communicating pipe 273 has an outer wall surface in tight contact with and connected to the fifth opening 2025b and the second hole 20231 by means of laser beam welding, welding or leakproof gasket, so as to prevent leakage of the working liquid 4 from the third and the fourth liquid chamber 2024a, 2024b.
According to the first embodiment, the water-cooling radiator assembly 2 of the present invention further includes a second flow disturbing member 22. The first and the second flow disturbing member 21, 22 provide the effects of disturbing liquid flows and forming a support in the first liquid-receiving plate 201. The first and the second flow disturbing member 21, 22 can be made of gold, silver, copper, iron, titanium, aluminum or stainless steel, or any alloy of these metal materials. The first and the second flow disturbing member 21, 22 are arranged in the first liquid chamber 2014a and the second liquid chamber 2014b, respectively. In the illustrated first embodiment, the first flow disturbing member 21 in the first liquid chamber 2014a has an upper side in contact with an inner surface of the first top plate member 2011 and a lower side in contact with an upper surface of the first partition member 2013; and the second flow disturbing member 22 in the second liquid chamber 2014b has an upper side in contact with a lower surface of the first partition member 2013 and a lower side in contact with an inner surface of the first bottom plate member 2012. In an operable embodiment of the present invention, the first flow disturbing member 21 can be omitted from the first liquid chamber 2014a, so that the water-cooling radiator assembly 2 has only the second flow disturbing member 22 arranged in the second liquid chamber 2014b. Alternatively, according to another operable embodiment, the second flow disturbing member 22 can be omitted from the second liquid chamber 2014b while the first liquid chamber 2014a has the first flow disturbing member 21 arranged therein.
Similarly, any two adjacent second flow disturbing elements 221 located in the same row and in two adjacent rows have shapes that are inverted relative to each other. The second flow disturbing elements 221 are located in the second liquid chamber 2014b to function as an internal structural support to the first liquid-receiving plate 201. The second flow disturbing elements 221 are respectively formed with a second flow disturbing means 2211, which is located on one side of each second flow disturbing element 221 that faces toward the second liquid passage 252. In an operable embodiment of the present invention, the first and the second flow disturbing means 2111, 2211 can be omitted from the first and the second flow disturbing elements 211, 221, respectively. In another operable embodiment, the first and the second flow disturbing member 21, 22 are integrally formed with the first partition member 2013 by way of, for example, 3D printing.
When the heat-carrying working liquid 4 flows into the second liquid chamber 2014b via the liquid inlet 2017 on the first liquid-receiving plate 201 and further flows through the second flow disturbing member 22 in the second liquid chamber 2014b, the working liquid 4 is disturbed and stirred by the second flow disturbing elements 221, so that streams of the working liquid 4 flowed through different second flow disturbing elements 221 reach a homogeneous temperature. Also, the working liquid 4 flowing through the second liquid passages 252 will strike against the second flow disturbing means 2211 to produce eddies, which increases the flow time of the working liquid 4 in the second liquid chamber 2014b and enables enhanced working liquid streams mixing effect and accordingly, effectively upgraded heat exchange efficiency. Meanwhile, heat carried by the working liquid 4 is directly absorbed by inner surfaces of the first liquid-receiving plate 201 and transferred to an outer side of the first liquid-receiving plate 201, from where the heat is dissipated into ambient air. After flowing through the second liquid passages 252, the working liquid 4 flows into the fourth liquid chamber 2024b via the first opening 2015a and the first communicating pipe 271. At this point, any heat remained in the working liquid 4 will be directly absorbed by inner surfaces of the second liquid-receiving plate 202 and transferred to an outer side of the second liquid-receiving plate 202, from where the heat is dissipated into ambient air. Then, the cooled working liquid 4 in the fourth liquid chamber 2024b flows into the first liquid chamber 2014a of the first liquid-receiving plate 201 via the sixth opening 2025c and the second communicating pipe 272. When the working liquid 4 flows through the first flow disturbing member 21 in the first liquid chamber 2014a, the working liquid 4 is disturbed and stirred by the first flow disturbing elements 211, so that streams of the working liquid 4 flowed through different first flow disturbing elements 211 reach a homogeneous temperature. Also, the working liquid 4 flowing through the first liquid passages 251 will strike against the first flow disturbing means 2111 to produce eddies, which increases the flow time of the working liquid 4 in the first liquid chamber 2014a and enables enhanced working liquid streams mixing effect and accordingly, effectively upgraded heat exchange efficiency. Meanwhile, the working liquid 4 flowing through the first flow passages 251 also absorbs the heat carried by the working liquid 4 that is currently in the second liquid chamber 2014b below the first partition member 2013, so that the working liquid 4 in the first liquid-receiving plate 201 can reach the homogenous temperature more efficiently through effective heat exchange and quick heat dissipation. Then, the working liquid 4, which is currently in the first liquid chamber 2014a and has just absorbed heat through heat exchange with the working liquid 4 in the second liquid chamber 2014b, flows through the first liquid passages 251 into the third liquid chamber 2024a via the third opening 2015b and the third communicating pipe 273. At this point, the heat carried by the working liquid 4 is directly absorbed by the inner surfaces of the second liquid-receiving plate 202 and transferred to the outer side of the second liquid-receiving plate 202, from where the heat is dissipated into ambient air. Finally, the cooled working liquid 4 leaves the second liquid-receiving plate 202 via the liquid outlet 2027.
Therefore, by providing the first and second partition members 2013, 2023 in the first and second liquid-receiving plates 201, 202, respectively, to form two independent horizontal liquid chambers in each of the first and the second liquid-receiving plate 201, 202, and by separately providing the first and the second flow disturbing member 21, 22 in the two independent liquid chambers in the first liquid-receiving plate 201, it is able to effectively extend the flow path and the flow time of the working liquid 4 in the first liquid-receiving plate 201 and accordingly, achieve the effects of more efficient heat exchange and quicker heat dissipation. More specifically, the first and the second flow disturbing elements 211, 221 of the first and the second flow disturbing member 21, 22, respectively, not only disturb and stir the working liquid 4 to extend the flow time of the working liquid 4 and enhance the mixing of different streams of the working liquid 4 in the liquid-receiving plate unit 20 to effectively upgrade the efficiency of heat exchange between the working liquid 4 and the first liquid-receiving plate 201, but also provide largely increased heat transfer areas to absorb and transfer the heat carried by the working liquid 4 to the corresponding first and second liquid-receiving plates 201, 202, from where the heat is dissipated into ambient air to achieve largely upgraded heat dissipation efficiency. The first and the second liquid-receiving plate 201, 202 of the liquid-receiving plate unit 20 also have relatively large inner surfaces, which are in direct contact with the flowing working liquid 4 to absorb the heat carried by the working liquid 4. The heat directly absorbed by the inner surfaces of the first and the second liquid-receiving plate 201, 202 is then quickly dissipated into ambient air from the relatively large outer surfaces of the first and the second liquid-receiving plate 201, 202. These arrangements enable the water-cooling radiator assembly 2 according to the first embodiment of the present invention to have increased heat dissipation areas and achieve good heat removal performance.
In an operable embodiment of the present invention, the first and the second liquid-receiving plate 201, 202 as well as the first communicating pipe 271 are made of a titanium material having a purity of 90% to 99.99%, such as the commercially pure titanium (CP-Ti). The titanium material has high metal strength, low weight and good heat transfer efficiency and is corrosion resistant to enable effectively upgraded heat transfer effect and reduced overall weight of the water-cooling radiator assembly 2. In the structural design of the present invention that combines the liquid-receiving plate unit 20 and the communicating pipe unit 27, the number and positions of the liquid-receiving plates as well as the number and positions of the communicating pipes between any two adjacent liquid-receiving plates can be actively adjusted or arranged in advance according to the internal space available in an electronic device (not shown) that requires water cooling, so that the heat dissipation effect can be adjusted in different manners.
The water-cooling radiator assembly 2 of the present invention can be applied to electronic equipment, industrial equipment, household appliances, transportation equipment, smart equipment and devices, etc. to cool or dissipate heat from the heat-producing electronic elements or heat sources in these equipment, appliances or devices.

In an operable embodiment of the present invention, the second flow passage 262 can be omitted from the second liquid chamber 2014b, so that the entire area, including the left and the right zone, in the second liquid chamber 2014b is occupied only by the second flow disturbing member 22.
According to the second embodiment, the working liquid 4 flowing through the second flow disturbing member 22 in the second liquid chamber 2014b is disturbed and stirred by the second flow disturbing elements 221, so that streams of the working liquid 4 flowed through different second flow disturbing elements 221 reach a homogeneous temperature. Then, the working liquid 4 flowing through the second liquid passages 252 will strike against the second flow disturbing means 2211 to produce eddies. After passing through the second liquid passages 252, the working liquid 4 flows along the winding second flow passage 262 toward the first opening 2015a, and then flows into the fourth liquid chamber 2024b via the first opening 2015a and the first communicating pipe 271. Then, the cooled working liquid 4 in the fourth liquid chamber 2024b flows into the first liquid chamber 2014a of the first liquid-receiving plate 201 via the sixth opening 2025c and the second communicating pipe 272. When the working liquid 4 flows through the first flow disturbing member 21 in the first liquid chamber 2014a, the working liquid 4 is disturbed and stirred by the first flow disturbing elements 211, so that streams of the working liquid 4 flowed through different first flow disturbing elements 211 reach a homogeneous temperature. Also, the working liquid 4 flowing through the first liquid passages 251 will strike against the first flow disturbing means 2111 to produce eddies. Meanwhile, the working liquid 4 flowing through the first flow passages 251 also absorbs the heat carried by the working liquid 4 that is currently in the second liquid chamber 2014b below the first partition member 2013, so that the working liquid 4 in the first liquid-receiving plate 201 can reach the homogenous temperature more efficiently through effective heat exchange and quick heat dissipation. Then, the working liquid 4, which is currently in the first liquid chamber 2014a and has just absorbed heat through heat exchange with the working liquid 4 in the second liquid chamber 2014b, flows through the first liquid passages 251 and keeps flowing along the winding first flow passage 261 toward the third opening 2015b. Thereafter, the working liquid 4 flows into the third liquid chamber 2024a via the third opening 2015b and the third communicating pipe 273. Finally, the cooled working liquid 4 leaves the second liquid-receiving plate 202 via the liquid outlet 2027. In brief, in the second embodiment of the present invention, the first liquid chamber 2014a is internally provided with two structures of different functions, i.e. the first flow disturbing member 21 and the first flow passage 261, while the second liquid chamber 2014b is also internally provided with another two structures of different functions, i.e. the second flow disturbing member 22 and the second flow passage 262. With these arrangements, it is able to lower the flow speed and increase the flow time of the working liquid 4 in the first liquid-receiving plate 201 and accordingly, largely upgrade the heat dissipation efficiency of the water-cooling radiator assembly 2 according to the second embodiment of the present invention.

In practical implementation of the third embodiment of the present invention, two opposite side surfaces of each of the first and the second flow disturbing elements 211, 221 are machined, for example, using a stamping mold to form the first and the second flow disturbing holes 213, 223, respectively. When the first and the second flow disturbing elements 211, 221 are stamped from a first side surface thereof to form the first and the second flow disturbing holes 213, 223, respectively, the first and the second lip portion 2131, 2231 will be formed on and protruded from an opposite second side surface of the first and the second flow disturbing elements 211, 221 around the so formed flow disturbing holes 213, 223. On the other hand, when the first and the second flow disturbing elements 211, 221 are stamped from the second side surface thereof to form the first and the second flow disturbing holes 213, 223, respectively, the first and the second lip portion 2131, 2231 will be formed on and protruded from the first side surface of the first and the second flow disturbing elements 211, 221 around the so formed flow disturbing holes 213, 223. When the working liquid 4 flows through the first and the second flow disturbing holes 213, 223, it strikes against the first and the second lip portions 2131, 2231, respectively, and is disturbed and stirred to extend its flow time in the first and the second liquid chamber 2014a, 2014b accordingly. Therefore, with the structural design of the first and the second flow disturbing elements 211, 221 that have the first and the second flow disturbing holes 213, 223 as well as the first and the second lip portions 2131, 2231 correspondingly formed thereon, the working liquid 4 passing through the first and the second flow disturbing holes 213, 223 will correspondingly strike against and be disturbed by the first and the second lip portions 2131, 2231 to increase the flow time of the working liquid 4 in the liquid-receiving plate unit 20 to thereby largely upgrade the heat dissipation efficiency or the heat exchange efficiency of the water-cooling radiator assembly 2 according to the third embodiment of the present invention. According to the third embodiment, the first and the second flow disturbing holes 213, 223 can be respectively a hexagonal hole, or any other polygonal hole, such as a triangular, a pentagonal or an octagonal hole, or any other geometric-shaped hole, such as a square or a rhombic hole.

The fourth flow disturbing member 24 includes a plurality of fourth flow disturbing elements 241, which are arranged in rows and lines to together define a plurality of fourth liquid passages 254 between them.
In the illustrated fourth embodiment, the third and fourth flow disturbing elements 231, 241 are respectively a wave-shaped plate. However, it is understood the third and fourth flow disturbing elements 231, 241 are not necessarily limited to wave-shaped plates. In practical implementation of the present invention, the third and fourth flow disturbing elements 231, 241 can be otherwise helical-shaped elements or any other geometric-shaped elements, such as square, rectangular or rhombic elements, arranged in rows and lines side-by-side. According to the present invention, any structure that can produce a flow disturbing or stirring effect to lower liquid flow speed and increase liquid flow time in the liquid chambers of the water-cooling radiator assembly 2 is included in the scope of the third and the fourth flow disturbing member 23, 24 of the present invention. Any two adjacent third flow disturbing elements 231 located in the same row and in two adjacent rows have shapes that are inverted relative to each other. The third flow disturbing elements 231 are located in the third liquid chamber 2024a to function as an internal structural support to the second liquid-receiving plate 202. The third flow disturbing elements 231 are respectively formed with a third flow disturbing means 2311, which is located on one side of each third flow disturbing element 231 that faces toward the third liquid passage 253.
Similarly, any two adjacent fourth flow disturbing elements 241 located in the same row and in two adjacent rows have shapes that are inverted relative to each other. The fourth flow disturbing elements 241 are located in the fourth liquid chamber 2024b to function as an internal structural support to the second liquid-receiving plate 202. The fourth flow disturbing elements 241 are respectively formed with a fourth flow disturbing means 2411, which is located on one side of each fourth flow disturbing element 241 that faces toward the fourth liquid passage 254. In an operable embodiment of the present invention, the third and the fourth flow disturbing means 2311, 2411 can be omitted from the third and the fourth flow disturbing elements 231, 241, respectively. In another operable embodiment, the third and the fourth flow disturbing member 23, 24 are integrally formed with the second partition member 2023 by way of, for example, 3D printing. The provision of the third and the fourth flow disturbing member 23, 24 can extend the flow time of the working liquid 4 and enhance the mixing of different streams of the working liquid 4 in the liquid-receiving plate unit 20 to effectively upgrade the efficiency of heat exchange between the working liquid 4 and the first and second liquid-receiving plates 201, 202 and achieve largely upgraded heat dissipation efficiency of the whole water-cooling radiator assembly 2.
According to an operable embodiment, the second and the fourth flow disturbing member 22, 24 can be omitted from the water-cooling radiator assembly 2 of the present invention. That is, only the first and the third liquid chamber 2014a, 2024a have the first and the third flow disturbing member 21, 23, respectively, provided therein. Alternatively, according to another operable embodiment, the first and the third flow disturbing member 21, 23 are omitted from the water-cooling radiator assembly 2 of the present invention. That is, only the second and the fourth liquid chamber 2014b, 2024b have the second and the fourth flow disturbing member 22, 24, respectively, provided therein. Or, according to a further operable embodiment, the third flow disturbing member 23 is omitted from the water-cooling radiator assembly 2 of the present invention. That is, only the first, the second and the fourth liquid chamber 2014a, 2014b, 2024b have the first, the second and the fourth flow disturbing member 21, 22, 24, respectively, provided therein.
Therefore, the water-cooling radiator assembly 2 with internal horizontal partition members 2013, 2023 and fluid disturbing members 21, 22, 23, 24 can have good heat removal performance and provide the effects of efficient heat exchange and quick heat dissipation. Since the structure of the present invention can effectively increase the flow time of the working liquid 4 in the water-cooling radiator assembly 2, the working liquid 4 can have sufficient time to exchange heat with the first and the second liquid-receiving plate 201, 202, enabling the present invention to have largely upgraded heat dissipation efficiency.

As shown, according to the fifth embodiment, the first flow disturbing member 21 and the first flow passage 261 in the first liquid chamber 2014a as well as the second flow disturbing member 22 and the second flow passage 262 in the second liquid chamber 2014b are structurally and functionally similar to those in the second embodiment, and are therefore not repeatedly described herein. Also, according to the fifth embodiment, since the flowing and the effects of the working liquid 4 in the first and second liquid-receiving plates 201, 202, the first and second flow disturbing members 21, 22, the first and second flow passages 261, 262, as well as the first, second and third communicating pipes 271, 272, 273 are similar to those in the second embodiment, they are not repeatedly described herein.
The fifth embodiment is different from the second embodiment in further including the third flow passage 263 and the fourth flow passage 264. The third flow passage 263 is provided in the third liquid chamber 2024a at a position laterally opposite to the third flow disturbing member 23. As can be seen in
According to the fifth embodiment, when the working liquid 4 flows into the fourth liquid chamber 2024b via the first communicating pipe 271 and passes the fourth flow disturbing elements 241, the working liquid 4 is disturbed and stirred by the fourth flow disturbing elements 241, so that streams of the working liquid 4 flowed through different fourth flow disturbing elements 241 reach a homogeneous temperature. Then, the working liquid 4 flowing through the fourth liquid passages 254 will strike against the fourth flow disturbing means 2411 to produce eddies. After passing through the fourth liquid passages 254, the working liquid 4 flows along the winding fourth flow passage 264 toward the sixth opening 2015c. Then the partially cooled working liquid 4 flows into the first liquid chamber 2014a of the first liquid-receiving plate 201 via the sixth opening 2015c and the second communicating pipe 272. When the working liquid 4 flows through the first flow disturbing member 21 in the first liquid chamber 2014a, the working liquid 4 is disturbed and stirred by the first flow disturbing elements 211, so that streams of the working liquid 4 flowed through different first flow disturbing elements 211 reach a homogeneous temperature. Also, the working liquid 4 flowing through the first liquid passages 251 will strike against the first flow disturbing means 2111 to produce eddies. Meanwhile, the working liquid 4 flowing through the first liquid passages 251 also absorbs the heat carried by the working liquid 4 that is currently in the second liquid chamber 2014b below the first partition member 2013, so that the working liquid 4 in the first liquid-receiving plate 201 can reach the homogenous temperature more efficiently through effective heat exchange and quick heat dissipation. Then, the working liquid 4, which is currently in the first liquid chamber 2014a and has just absorbed heat through heat exchange with the working liquid 4 in the second liquid chamber 2014b, flows through the first liquid passages 251 and keeps flowing along the winding first flow passage 261 toward the third opening 2015b. Thereafter, the working liquid 4 flows into the third liquid chamber 2024a via the third opening 2015b and the third communicating pipe 273 to flow along the winding third flow passage 263 toward the liquid outlet 2027. When passing the third flow disturbing member 23, the working liquid 4 is disturbed and stirred by the third flow disturbing elements 231, so that streams of the working liquid 4 flowed through different third flow disturbing elements 231 reach a homogeneous temperature. Then, the working liquid 4 flowing through the third liquid passages 253 will strike against the third flow disturbing means 2311 to produce eddies. Finally, after passing the third liquid passages 253, the cooled working liquid 4 leaves the second liquid-receiving plate 202 via the liquid outlet 2027. With these arrangements, the water-cooling radiator assembly 2 according to the fifth embodiment of the present invention can have effectively improved heat removal performance and sufficient heat exchange to achieve quick heat dissipation effect; and the flow time of the working liquid 4 in the first and the second liquid-receiving plate 201, 202 is effectively increased to enable largely upgraded heat dissipation efficiency of the water-cooling radiator assembly 2 of the present invention.

As can be clearly seen in
In practical implementation of the sixth embodiment of the present invention, just like the first and the second flow disturbing elements 211, 221, each of the third and the fourth flow disturbing elements 231, 241 are machined, for example, using a stamping mold to form the third and the fourth flow disturbing holes 233, 243, respectively. Since the forming of the first and the second flow disturbing holes 213, 223 on the first and the second flow disturbing elements 211, 221 has been described in the third embodiment of the present invention, the forming of the third and the fourth flow disturbing holes 233, 243 is not repeatedly described herein. Therefore, with the structural design of the first, the second, the third and the fourth flow disturbing elements 211, 221, 231, 241 that have the first, the second, the third and the fourth flow disturbing holes 213, 223, 233, 243 as well as the first, the second, the third and the fourth lip portions 2131, 2231, 2331, 2431 correspondingly formed thereon, the working liquid 4 passing through the first, second, third and fourth flow disturbing holes 213, 223, 233, 243 will correspondingly strike against and be disturbed by the first, second, third and fourth lip portions 2131, 2231, 2331, 2431 to increase the flow time of the working liquid 4 in the liquid-receiving plate unit 20 to thereby largely upgrade the heat dissipation efficiency or the heat exchange efficiency of the water-cooling radiator assembly 2 according to the sixth embodiment of the present invention.
In an operable embodiment, the protection cover unit 5 and the cooling fan bank 6 can be optionally omitted. In another operable embodiment, the protection cover unit 5 can be provided with a fastening unit (not shown) to firmly secure the water-cooling radiator assembly 2 to a carrier, such as a chassis or a motherboard.
In practical implementation of the present invention, the liquid outlet 2027 on the second liquid-receiving plate 202 is communicably connected to an end of a corresponding pump (not shown), and a cooling module (not shown) in contact with a heat source, such as a CPU or other heat-producing electronic element, can be correspondingly connected to another end of the pump and communicable with the liquid inlet 2017 on the first liquid-receiving plate 201, so that the water-cooling radiator assembly 2, the pump and the cooling module together constitute a water-cooling system. The pump drives or stirs the working liquid 4 to repeatedly circulate between the cooling module and the liquid-receiving plate unit 20 to effectively enable good heat removal performance and quick heat dissipation through heat exchange.
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.
