[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0029] The present invention provides a liquid cooling row structure, which is used to allow a coolant to flow through the structure in a single direction, thereby cooling and dissipating the coolant. Figures 1 to 4 As shown, the first embodiment of the liquid cooling radiator structure of the present invention mainly includes a first water tank 10 , a second water tank 20 , a first heat dissipation module 30 , a second heat dissipation module 40 and a plurality of heat dissipation fins 50 .

[0030] The first water tank 10 has a liquid inlet chamber 11 and a liquid outlet chamber 12 arranged adjacent to each other. The liquid inlet chamber 11 has a liquid inlet 111 and a first flow diversion position 112. The liquid outlet chamber 12 has a liquid outlet 121 and a first flow confluence position 122. In this embodiment, the liquid inlet 111 and the liquid outlet 121 are both hollow joints, so that a liquid infusion tube (not shown) can be inserted respectively to connect a liquid cooling head A to infuse cooling liquid, such as Figure 1 As shown. The liquid inlet 111 and the liquid outlet 121 are arranged adjacent to each other. Specifically, the liquid inlet 111 is located at the liquid outlet chamber 12 adjacent to the liquid inlet chamber 11, and the liquid outlet 121 is located at the liquid outlet chamber 12 adjacent to the liquid inlet chamber 11. In this way, compared with the two liquid infusion pipes of the traditional liquid cooling radiator located at the two sides of the water tank, the liquid cooling radiator structure of the present invention can facilitate the routing and arrangement of the two adjacent liquid infusion pipes, and greatly reduce the space occupied by each liquid infusion pipe.

[0031] The second water tank 20 has a second confluence position 201 and a second diversion position 202. The first diversion position 112, the first confluence position 122, the second confluence position 201 and the second diversion position 202 are arranged together in a triangular shape. Specifically, the first diversion position 112 and the second confluence position 201 are respectively located at the diagonal corners of the first heat dissipation module 30, and the second diversion position 202 and the first confluence position 122 are respectively located at the diagonal corners of the second heat dissipation module 40, so as to be arranged together in a triangular shape. The detailed specific positions and related structures of the first diversion position 112, the first confluence position 122, the second confluence position 201 and the second diversion position 202 will be described as follows.

[0032] The first heat dissipation module 30 includes a plurality of first pipes 31. The first pipes 31 are parallel to each other, and the two ends of each first pipe 31 are respectively connected to the liquid inlet chamber 11 and the second water tank 20. The second heat dissipation module 40 includes a plurality of second pipes 41. The second pipes 41 are parallel to each other, and the two ends of each second pipe 41 are respectively connected to the second water tank 20 and the liquid outlet chamber 12. The second confluence position 201 is configured corresponding to the first heat dissipation module 30. The second diversion position 202 is configured corresponding to the second heat dissipation module 40. A portion of the heat dissipation fins 50 are arranged between the first pipes 31, and the remaining portion of the heat dissipation fins 50 are arranged between the second pipes 41. In this embodiment, the heat dissipation fins 50 are connected between the pipes in a wave shape, but the present invention is not limited thereto.

[0033] Further, the second water tank 20 in this embodiment includes a liquid inlet tank 21, a liquid outlet tank 22 and an additional water tank 60. The liquid inlet chamber 11 is connected to the liquid inlet tank 21 via each first pipe 31. The liquid inlet tank 21 is connected to the liquid outlet tank 22 via the additional water tank 60. The liquid outlet tank 22 is connected to the liquid outlet chamber 12 via each second pipe 41. In this embodiment, the connection between the liquid inlet tank 21 and the additional water tank 60, and the connection between the liquid outlet tank 22 and the additional water tank 60 are respectively located at the two ends of the additional water tank 60, such as Figure 2 and Figure 4 shown.

[0034] Please continue reading Figure 4 As shown, the first flow splitting position 112 in this embodiment is located at the liquid inlet 111, the first flow converging position 122 is located at the liquid outlet 121, the second flow converging position 201 is located at the connection between the liquid inlet tank 21 and the additional water tank 60, and the second flow splitting position 202 is located at the connection between the liquid outlet tank 22 and the additional water tank 60. Thus, since the first flow splitting position 112, the first flow converging position 122, the second flow converging position 201 and the second flow splitting position 202 in this embodiment are arranged together to present a triangular shape with the tip gradually shrinking toward the right side of the figure, the coolant can evenly pass through each first pipe 31 / each second pipe 41 after dispersion / convergence, thereby ensuring that each first pipe 31 / second pipe 41 can optimize the heat dissipation effect.

[0035] Specifically, in this embodiment, after the coolant enters the liquid inlet chamber 11 from the liquid inlet 111, it can be dispersed from the first diversion position 112 and enter each first pipe 31, and when passing through each first pipe 31, it can be cooled by each heat dissipation fin 50 in the first stage and flow into the liquid inlet tank 21, and then converge to the second confluence position 201 and flow to the second diversion position 202 through the additional water tank 60, so as to be diverted to the liquid outlet tank 22 to enter each second pipe 41, and when passing through each second pipe 41, it can be cooled by each heat dissipation fin 50 in the second stage and flow into the liquid outlet chamber 12, and finally converge to the first confluence position 122 and leave from the liquid outlet 121. Therefore, whether the coolant flows from the liquid inlet chamber 11 to the liquid inlet tank 21 or from the liquid outlet tank 22 to the liquid outlet chamber 12, it can have a flow path of similar length, so as to be evenly dispersed in each first pipe 31 or each second pipe 41.

[0036] For further instructions, see Figure 2As shown, the liquid cooling row structure of the present invention also includes a sealing rubber ring 61 and a plurality of bolts 62. Each bolt 62 passes through the additional water tank 60 and is locked to the liquid inlet groove 21 and the liquid outlet groove 22, thereby fixing the additional water tank 60. The additional water tank 60 is provided with a groove 601 on one side facing the liquid inlet groove 21 and the liquid outlet groove 22. The groove 601 is in the shape of a long strip, and the middle area of ​​the groove 601 is hollow and penetrates into the interior of the additional water tank 60. The liquid inlet groove 21 and the liquid outlet groove 22 are respectively provided with a notch 203, and each notch 203 is respectively located at the two ends of the interior of the groove 601. The second confluence position 201 and the second diversion position 202 are respectively located at each notch 203 and located in the groove 601. The sealing rubber ring 61 is sleeved on the outer edge of the groove 601 and pre-pressed to abut between the additional water tank 60 and the liquid inlet groove 21 and the liquid outlet groove 22. Thereby, the coolant in the liquid inlet groove 21 is connected to the additional water tank 60 via the notch 203, and the coolant in the additional water tank 60 is connected to the liquid outlet groove 22 via another notch 203, and the sealing rubber ring 61 sleeved on the outer edge of the groove 601 can effectively ensure the sealing to prevent the coolant from leaking.

[0037] Please read next Figure 5 As shown, the second embodiment of the present invention is different from the first embodiment in that the additional water tank 60 is replaced by a bridge tube 70. Specifically, the second water tank 20 in this embodiment includes an inlet tank 21, an outlet tank 22 and a bridge tube 70. The inlet chamber 11 is connected to the inlet tank 21 via each first pipe 31. The inlet tank 21 is connected to the outlet tank 22 via the bridge tube 70. The outlet tank 22 is connected to the outlet chamber 12 via each second pipe 41. In this embodiment, the two ends of the bridge tube 70 are respectively located at the divergent positions of the inlet tank 21 and the outlet tank 22, that is, respectively located at the farthest two ends. The second confluence position 201 is located at the connection point between the inlet tank 21 and the bridge tube 70, and the second diversion position 202 is located at the connection point between the outlet tank 22 and the bridge tube 70. Thereby, the first diversion position 112, the first confluence position 122, the second confluence position 201 and the second diversion position 202 in this embodiment are still arranged together in the same triangular shape as the first embodiment to achieve the same flow equalization effect, and at the same time reduce the additional water tank 60, the sealing rubber ring 61 and the plurality of bolts 62 and other components, which can reduce costs, reduce material preparation, and facilitate assembly, maintenance and repair.

[0038] Please refer to Figure 6As shown, the third embodiment of the present invention is different from the first embodiment in that the second water tank 20 is not provided with a liquid inlet tank 21, a liquid outlet tank 22 and an additional water tank 60, but a partition 80 is directly provided in the second water tank 20. Specifically, the partition 80 includes a connecting plate 81 and a flow guide member 83. One end of the connecting plate 81 is provided on the inner wall of the second water tank 20 and is located between the first heat dissipation module 30 and the second heat dissipation module 40. The flow guide member 83 is vertically connected to the other end of the connecting plate 81, so that a notch 203 is formed on the other two adjacent inner walls of the second water tank 20. The second confluence position 201 and the second diversion position 202 are respectively located at the two ends of the flow guide member 83, that is, the second confluence position 201 and the second diversion position 202 are respectively located at each notch 203.

[0039] In this embodiment, the flow guide member 83 is a hollow tube. The hollow tube is attached to another inner wall arranged relative to the connecting plate 81, and a flow channel is provided inside the hollow tube. The second confluence position 201 is connected to the second diversion position 202 via the flow channel. However, the present invention is not limited to the above, for example, in other embodiments, the flow guide member 83 may also be a partition extending vertically in both directions from the end of the connecting plate 81, so that the partition 80 is T-shaped, and a flow channel is formed between the flow guide member 83 and the inner wall of the second water tank 20 to connect the second confluence position 201 with the second diversion position 202.

[0040] Thus, the connecting plate 81 and the flow guide member 83 block and limit the flow, so that the coolant flowing out of each first pipe 31 can be limited by the side edge of the flow guide member 83 and converge to the second converging position 201, and flow to the second flow diversion position 202 through the flow channel, and finally divert from the second flow diversion position 202 to each second pipe 41, thereby achieving the same flow equalization effect as the first embodiment and the second embodiment. In addition, since the partition 80 is directly disposed inside the second water tank 20, the second water tank 20 can have the best sealing performance, while reducing the volume to save space.

[0041] Please refer to Figure 7As shown, the fourth embodiment of the present invention is different from the first embodiment in the specific structure of the first water tank 10 and the second water tank 20, which is described in detail as follows. In this embodiment, the first water tank 10 includes a water tank body 13 and an additional water tank 60. The water tank body 13 is separated into a first water chamber 131 and a second water chamber 132, and the additional water tank 60 is separated into a third water chamber 63 and a fourth water chamber 64. The first water chamber 131 is connected to the third water chamber 63 and together constitutes the liquid inlet chamber 11, and the second water chamber 132 is connected to the fourth water chamber 64 and together constitutes the liquid outlet chamber 12. The liquid inlet 111 and the liquid outlet 121 are respectively located in the third water chamber 63 and the fourth water chamber 64. And the connection between the first water chamber 131 and the third water chamber 63, and the connection between the second water chamber 132 and the fourth water chamber 64 are respectively located at the two ends of the additional water tank 60.

[0042] In this embodiment, the first flow diversion position 112 is located at the connection between the first water chamber 131 and the third water chamber 63, the first confluence position 122 is located at the connection between the second water chamber 132 and the fourth water chamber 64, and the second confluence position 201 and the second flow diversion position 202 are adjacently arranged and located adjacent to the first heat dissipation module 30 and the second heat dissipation module 40 in the second water tank 20. Thus, the first flow diversion position 112, the first confluence position 122, the second confluence position 201 and the second flow diversion position 202 in this embodiment are arranged together to present a triangular shape with the tip gradually shrinking toward the left side of the figure, so that the coolant can evenly pass through each first pipe 31 / each second pipe 41 after dispersion / confluence, thereby ensuring that each first pipe 31 / second pipe 41 can optimize the heat dissipation effect.

[0043] Specifically, in this embodiment, after the coolant enters the third water chamber 63 of the liquid inlet chamber 11 from the liquid inlet 111, it can flow to the first diversion position 112 and disperse into the first water chamber 131 to enter each first pipe 31, and when passing through each first pipe 31, it can perform the first stage of heat dissipation and cooling through each heat dissipation fin 50 and flow into the second water tank 20, and then converge to the second confluence position 201 and the second diversion position 202, and divert from the second diversion position 202 into each second pipe 41, and when passing through each second pipe 41, it can perform the second stage of heat dissipation and cooling through each heat dissipation fin 50 and flow into the second water chamber 132 of the liquid outlet chamber 12, and finally converge at the first confluence position 122 to enter the fourth water chamber 64 and leave from the liquid outlet 121. Therefore, no matter the coolant flows from the liquid inlet chamber 11 to the second water tank 20 or from the second water tank 20 to the liquid outlet chamber 12 , the coolant can have a flow path of similar length, thereby being evenly dispersed in each first pipe 31 or each second pipe 41 .

[0044] Please refer to Figure 8As shown, the fifth embodiment of the present invention is different from the fourth embodiment in that the first water tank 10 is not provided with a water tank body 13 and an additional water tank 60, but a partition 80 is directly provided in the first water tank 10. Specifically, the partition 80 includes a connecting plate 81 and a pair of baffles 82. The two ends of the connecting plate 81 are arranged on the inner walls of the first water tank 10 on both sides opposite to each other, and the interior of the first water tank 10 is divided into a liquid inlet chamber 11 and a liquid outlet chamber 12. Each baffle 82 extends vertically from the two side surfaces of the center of the connecting plate 81 in opposite directions, thereby forming a notch 101 with the inner wall of the first water tank 10. The first diversion position 112 and the first confluence position 122 are respectively located at each notch 101.

[0045] Thus, the partition 80 in this embodiment is in a cross shape, so that the coolant entering the third water chamber 63 from the liquid inlet 111 can flow to the first diversion position 112 through the restriction of the baffle 82, and then divert to each first pipe 31 in the first water chamber 131; and when the coolant enters the third water chamber 63 from each second pipe 41, it can flow to the first confluence position 122 through the restriction of the baffle 82, and finally enter the fourth water chamber 64 and leave from the liquid outlet 121, thereby achieving the same flow equalization effect as the fourth embodiment. In addition, since the partition 80 is directly arranged inside the first water tank 10, the first water tank 10 can have the best sealing performance, while reducing the volume to save space.

Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention.
