Description

[Technical Field]

[0001] This invention relates to a heat exchange device, and more particularly to a liquid-cooled heat exchange device that uses liquid for heat exchange. [Previous Technology]

[0002] With the advancement of computer technology, the functions of the central processing unit in the server have become more and more powerful. Therefore, in order to provide better processing performance of the central processing unit, heat dissipation structures such as heat sinks or fans are usually installed to achieve heat dissipation through the flow of air.

[0003] However, although these heat sinks or fans used to dissipate the heat generated by the central processing unit can quickly conduct the heat generated by the central processing unit to each fin for cooling, and even increase the airflow effect through the structure of the fan, the heat dissipation effect of the air generated by the fan between the fins is limited due to the limited spacing between each fin. Therefore, it is necessary to provide a device that can exchange heat with a cooling liquid to improve the above-mentioned shortcomings. [Summary of the Invention]

[0004] The purpose of this invention is to provide a liquid-cooled heat exchange device that increases heat dissipation efficiency by accommodating a heat dissipation module.

[0005] To achieve the above objectives, the liquid-cooled heat exchange device provided by the present invention achieves heat dissipation through heat exchange with liquid. The liquid-cooled heat exchange device mainly includes a cover module, a base module, a flow guide plate, a partition unit, and a heat dissipation module. One side of the cover module is provided with a first through hole and a second through hole, and the first through hole connects to a first tube, and the second through hole connects to a second tube. The base module is assembled on the other side of the cover module. The flow guide plate is assembled and housed between the cover module and the base module, and the flow guide plate has an array of a plurality of inlet holes and an adjacent plurality of... Outlet hole; the spacer unit is disposed between the guide plate body and the cover module, wherein the spacer unit forms a first space and an adjacent second space between the guide plate body and the cover module; and the heat dissipation module is provided with a plurality of protrusions, a plurality of recesses and a plurality of connecting parts, wherein the protrusions and recesses are staggered along the same direction, and each protrusion is provided with a connecting part that communicates with the adjacent recesses; wherein liquid flows in from the first tube and sequentially flows through the first space, a third space and the second space, and then flows out from the second tube; and the guide plate body is provided with the spacer unit protruding between the inlet holes and the outlet holes.

[0006] Furthermore, the heat dissipation module is provided with a hollowed-out part at each position corresponding to the outlet hole.

[0007] Further, the heat dissipation module is provided with a plurality of connecting portions along a first direction, and each of the connecting portions is connected along the first direction to the protrusions that protrude toward a second direction.

[0008] Further, a plurality of upright portions are provided between two adjacent connecting portions, the upright portions being provided between the protrusions and recesses of the two adjacent connecting portions, and the two adjacent connecting portions being spaced apart to form the connecting portions.

[0009] Furthermore, the spacer unit is a frame and is welded between the flow guide plate and the cover module.

[0010] Further, the partition unit is a partition structure protruding between the inlet holes and the outlet holes, and the partition unit makes the first space and the second space form between the cover module and the guide plate body.

[0011] Furthermore, when the first through hole and the second through hole are projected onto the guide plate body, they will not overlap with one of the inlet holes or one of the outlet holes.

[0012] Further, the inlet holes are arranged in either an array or an irregular distribution, and the width of each inlet diameter of the inlet holes is less than or equal to the width of each outlet diameter of the outlet holes but greater than zero.

The liquid transported by the second pipe is cooled by the cooling unit and then transported to the liquid storage unit by the liquid pump unit. The liquid contained in the liquid storage unit is then transported to the first pipe.

[0015] The liquid-cooled heat exchange device of the present invention is connected to both ends of the cooling heat dissipation module through the first tube and the second tube respectively, so that the cooling liquid enters from the first through hole connected to the first tube and flows out from the second through hole connected to the second tube. The spacer unit forms the first space and the second space between the cover module and the guide plate. The guide plate forms not only inlet holes corresponding to the first space, but also outlet holes in the second space, and forms the third space between the guide plate and the base module. By accommodating the heat dissipation module having the protrusions, recesses, connecting portions, and upright portions, liquid entering through the first through hole forms a substantially uniform pressure distribution in the first space, then flows through the inlet holes to the third space where it is dissipated by the heat dissipation module, and then is guided through the outlet portions at the hollow structure to the second space corresponding to the outlet portions, and flows out through the second through holes to the second tube body to the cooling heat dissipation module. Thus, the liquid-cooled heat exchange device increases heat dissipation efficiency through the guide plate and the heat dissipation module. [Simplified Explanation of the Diagram]

[0017] Regarding the technology of this invention, please refer to Figures 1 to 10. This invention provides a liquid-cooled heat exchange device 100 that achieves heat dissipation through heat exchange with a liquid. The liquid can be a coolant, water, or a liquid with heat absorption properties. The liquid-cooled heat exchange device 100 mainly includes a cover module 10, a base module 20, a guide plate 30, a partition unit 40, and a heat dissipation module 50. The cover module 10 has a first through hole 11 and a second through hole on one side. Hole 12, and the first through hole 11 connects to a first tube body 13, and the second through hole 12 connects to a second tube body 14; the base module 20 is assembled on the other side of the cover module 10, and the base module 20 is provided with a plurality of locking holes 21. In this embodiment, the base module 20 is assembled with the cover module 10 by welding. In this embodiment, the side of the base module 20 opposite to the cover module 10 is provided with a bottom groove (not numbered). The bottom groove is used to assemble and accommodate the cover module 10, but not for... This is a limitation; the guide plate 30 is assembled and housed between the cover module 10 and the base module 20, forming a third space 31 between the guide plate 30 and the base module 20, and has a plurality of inlet holes 32 and adjacent plurality of outlet holes 33. In this embodiment, the inlet holes 32 are arranged in an array, but this is not a limitation; the inlet holes 32 can also be arranged irregularly. The spacer unit 40 is assembled between the guide plate 30 and the cover module 10, wherein the spacer unit 40 enables the... A first space 41 and an adjacent second space 42 are formed between the flow guide plate 30 and the cover module 10. In this embodiment, the partition unit 40 is a frame and is welded between the flow guide plate 30 and the cover module 10. However, this is not a limitation. Please refer to Figure 9. The partition unit 40 can also be a partition structure protruding between the inlet holes 32 and the outlet holes 33. The partition unit 40 makes the first space 41 and the second space 42 form between the cover module 10 and the flow guide plate 30.And the heat dissipation module 50, as shown in Figures 2 to 4, has a plurality of protrusions 51, a plurality of recesses 52, and a plurality of connecting portions 53. The protrusions 51 and the recesses 52 are staggered along the same direction, and each protrusion 51 is provided with a connecting portion 53 that communicates with the adjacent recesses 52. The heat dissipation module 50 has a plurality of connecting portions 54 along a first direction D1, and each connecting portion 54 is connected to a protrusion along the first direction D1 towards a second direction D2. The protruding portions 51 are provided, and a plurality of upright portions 55 are provided between two adjacent connecting portions 54. The upright portions 55 are provided between the protruding portions 51 and the recessed portions 52 of the two adjacent connecting portions 54, and the two adjacent connecting portions 54 are spaced to form the communicating portions 53. In addition, the heat dissipation module 50 of this embodiment is provided with a hollowed-out portion 56 at the position of the outlet holes 33, but it is not limited thereto. As shown in Figures 2, 6, 7 and 8, the liquid flows from the first tube 1 3. The liquid flows in and sequentially through the first space 41, the third space 31, and the second space 42, and then flows out from the second pipe 14. The liquid system flows into the third space 31 from the inlet holes 32 corresponding to the connecting parts 54 of the heat dissipation module 50, and then flows through the heat dissipation module 50 in the third space 31 to the second space 42 from the outlet holes 33 corresponding to the outlet parts 56. When the first through hole 11 and the second through hole 12 are projected onto the guide plate 30, the first through hole 11 and the second through hole 12... The through hole 12 does not overlap with any of the inlet holes 32 or any of the outlet holes 33; and the guide plate body 30 has the spacer unit 40 protruding between the inlet holes 32 and the outlet holes 33, and each of the inlet holes 32 has an inlet diameter width R1 and each of the outlet holes 33 has an outlet diameter width R2. In this embodiment, the inlet diameter width R1 is smaller than the outlet diameter width R2 but greater than zero, but this is not a limitation. The inlet diameter width R1 and the outlet diameter width R2 can be different from each other or approximately the same.

[0018] Please refer to Figures 1 to 9. The liquid-cooled heat exchange device 100 sequentially assembles the guide plate 30, the partition unit 40, and the heat dissipation module 50 between the cover module 10 and the base module 20. The partition unit 40 forms the first space 41 and the second space 42 between the cover module 10 and the guide plate 30, allowing liquid to flow from the first pipe 13 through the first through hole 11 into the first space 41. The pressure generated by the liquid in the first space 41 is made approximately uniform, and the liquid flows into the third space 31 through the guide holes 32 corresponding to the first space 41. At this time, the liquid absorbs the heat generated by the equipment assembled in the base module 20, and the liquid dissipates heat through the heat dissipation module 50, that is, the liquid dissipates heat through the guide holes 32. After flowing into the third space 31, the liquid will flow between the connecting parts 53 formed by the protrusions 51, the recesses 52, the connecting parts 53 and the upright parts 55. In this way, the liquid can increase the heat dissipation efficiency by utilizing the surface area of ​​the heat dissipation module 50, and then guide the liquid to the outlet parts 56 with the hollow structure. The liquid flows from the third space 31 through the outlet holes 33 to the second space 42, and then is output through the second tube 14 connected by the second through hole 12. The inlet diameter R1 of the inlet holes 32 is smaller than the outlet diameter R2 of the outlet holes 33. In this way, the liquid can be guided from the first space 41 through the third space 31 to the second space 42 by generating different pressures, and the heat absorbed by the liquid is reduced by the heat dissipation module 50 to achieve heat dissipation efficiency.

[0019] Furthermore, please refer to Figure 10. A cooling and heat dissipation module 60 is connected between the first tube 13 and the second tube 14 of the liquid-cooled heat exchange device 100. The cooling and heat dissipation module 60 includes a liquid pump unit 61, a cooling unit 62, and a liquid storage unit 63. One end of the liquid pump unit 61 is connected to the cooling unit 62, and the other end is connected to the liquid storage unit 63. The liquid transported from the second tube 14 is cooled by the cooling unit 62 and then transported to the liquid storage unit 63 by the liquid pump unit 61. The liquid contained in the liquid storage unit 63 is then cooled by the cooling unit 62. The liquid is delivered to the first tube 13. In this way, the liquid output from the second tube 14 can pass through the cooling unit 62 to reduce the temperature of the liquid delivered to the second tube 14. Then, the liquid pump unit 61 delivers the liquid through the storage unit 63 to the first tube 13. The liquid flows through the cooling unit 62 to reduce its temperature. Then, the cooled liquid flows back to the first tube 13 and is introduced into the first space 41. In this way, the liquid-cooled heat exchange device 100 can increase the heat dissipation efficiency of the liquid by connecting to the cooling heat dissipation module 60 and through the cooling unit 62.

[0020] In summary, the liquid-cooled heat exchange device 100 of the present invention is connected to both ends of the cooling heat dissipation module 60 through the first tube 13 and the second tube 14 respectively, so that the cooling liquid enters from the first through hole 11 connected to the first tube 13 and flows out from the second through hole 12 connected to the second tube 14. The spacer unit 40 forms the first space 41 and the second space 42 between the cover module 10 and the guide plate 30. The guide plate 30 not only forms inlet holes 32 corresponding to the first space 41, but also outlet holes 33 in the second space 42, and forms the third space 3 between the guide plate 30 and the base module 20. 1. The heat dissipation module 50, which accommodates the protrusions 51, the recesses 52, the connecting portions 53, the connecting portions 54, and the upright portions 55, allows the liquid entering through the first through hole 11 to form a generally uniform pressure distribution in the first space 41. The liquid then flows through the inlet holes 32 to the third space 31 where it is dissipated by the heat dissipation module 50. The liquid is then guided through the outlet portions 56 at the hollow structure to the second space 42 corresponding to the outlet portions 56, and flows out through the second through holes 12 toward the second tube 14 to the cooling heat dissipation module 60. Thus, the liquid-cooled heat exchange device 100 increases its heat dissipation efficiency through the guide plate 30 and the heat dissipation module 50.
