Description

Technical Field

[0001] This case relates to a water-cooled radiator, and more particularly to a water-cooled plate assembly. Background Technology

[0002] Cold plates typically feature internal flow channels and heat sinks to allow coolant to circulate and dissipate heat. The design of these flow channels often affects coolant flow rate and heat dissipation efficiency. Furthermore, the heat sinks of cold plates are mostly made of high-density metals (such as copper or aluminum alloys), which, while offering good thermal conductivity, result in greater overall weight and higher manufacturing costs, making it difficult to achieve both lightweight design and efficient heat dissipation.

[0003] Therefore, the inventors' research motivation is to find a way to effectively address the shortcomings of traditional water-cooled plate flow channel structure and heat sink design, so as to significantly improve cooling performance and reduce structural weight and make it suitable for a wider range of cooling needs.

[0004] In view of this, in order to achieve the above-mentioned objectives, the inventors have devoted themselves to research and applied theoretical principles, and finally proposed a design that is reasonable and effectively improves the above-mentioned deficiencies. Utility Model Content

[0007] One objective of this application is to provide a water-cooled plate assembly that enables lightweight construction and improves cooling performance.

[0008] To achieve the above objectives, this invention relates to a water-cooled plate assembly, including a housing and a heat dissipation fin assembly. The housing has an inner cavity containing a first cooling section, a second cooling section, and a third cooling section located between the first and second cooling sections. The first cooling section has a water inlet direction, and the second cooling section has a water outlet direction. The heat dissipation fin assembly includes a first fin assembly disposed in the first cooling section and a second fin assembly disposed in the second cooling section. The first fin assembly includes a plurality of parallel and spaced-apart first fins and has a first extension line parallel to the extension direction of the first fins. The second fin assembly includes a plurality of parallel and spaced-apart second fins and has a second extension line parallel to the extension direction of the second fins. The first extension line is approximately parallel to the water inlet direction, and the second extension line is disposed at a first angle to the water outlet direction.

The second fin group includes second fins disposed in parallel and at intervals. The second fin group has a second extension line parallel to the extension direction of the second fins. The second extension line is disposed at a first angle to the water outlet direction.

The fourth extension line is disposed at a third angle to the water outlet direction.

[0013] In one embodiment of this case, the second fin group, the third fin group, and the fourth fin group each maintain a gap with the inner wall surface of the inner cavity.

[0014] In one embodiment of this invention, the inner chamber includes a first chamber located in a first cooling section, a second chamber located in a second cooling section, and a third chamber located in a third cooling section, wherein the height of the first chamber and the second chamber is greater than the height of the third chamber.

The two opposing inner wall surfaces of the inlet of the first cooling section are respectively curved, and the two opposing inner wall surfaces of the outlet of the second cooling section are also respectively curved. Furthermore, the internal flow channels of the housing gradually narrow from the first chamber towards the third and second chambers, thereby reducing water flow resistance and improving the flow rate and heat dissipation efficiency of the coolant. Moreover, the heat dissipation fin assembly of this invention comprises a first fin assembly located in the first cooling section, a second fin assembly located in the second cooling section, and a third and fourth fin assembly located in the third cooling section.

[0081] The detailed description and technical content of this case are illustrated below with reference to the accompanying drawings. However, the drawings are provided for reference and illustration only and are not intended to limit the scope of this case.

[0082] Please refer to Figure 1 and Figure 2 These are three-dimensional external schematic diagrams of the water-cooled plate assembly in this case from two different directions. The water-cooled plate assembly 1 of this case includes a housing 10 and a heat dissipation fin assembly 20. The housing 10 has an inner cavity 100, which includes a first cooling section 11, a second cooling section 12, and a third cooling section 13 located between the first cooling section 11 and the second cooling section 12. The first cooling section 11 has a water inlet 110, and the two opposing inner wall surfaces of the water inlet 110 are inlet arc surfaces 111. The second cooling section 12 has a water outlet 120, and the two opposing inner wall surfaces of the water outlet 120 are outlet arc surfaces 121. Furthermore, the heat dissipation fin assembly 20 is disposed within the inner cavity 100, thereby constituting the water-cooled plate assembly 1.

[0083] It should be noted that the aforementioned inlet arc surface 111 and outlet arc surface 121 refer to a concave arc surface of the inner wall surface of the shell 10 at the water inlet and water outlet, which has a curvature change.

[0084] In this embodiment, the housing 10 includes a first housing plate 101 and a second housing plate 102. The first housing plate 101 and the second housing plate 102 overlap each other to form an inner cavity 100 for accommodating the heat dissipation fin assembly 20. It should be noted that the second housing plate 102 has multiple locking tabs 103 for fixing the water-cooled plate assembly 1. Furthermore, the housing 10 is also provided with a water inlet pipe 14 and a water outlet pipe 15. The water inlet pipe 14 passes through a water inlet 110, and the water outlet pipe 15 passes through a water outlet 120.

[0085] Please refer to another source. Figure 3 and Figure 4The figures shown are an exploded perspective view and a cross-sectional view of the water-cooled plate assembly of this invention. The housing 10 of the water-cooled plate assembly 1 is formed by clamping a first housing plate 101 and a second housing plate 102, and has a first cooling section 11, a second cooling section 12, and a third cooling section 13. Furthermore, the first cooling section 11 is provided with a water inlet pipe 14 and has a water inlet direction 1100. The second cooling section 12 is provided with a water outlet pipe 15 and has a water outlet direction 1200. It should be noted that the third cooling section 13 of this invention connects the first cooling section 11 and the second cooling section 12. Moreover, the outer contour of the third cooling section 13 can be U-shaped or L-shaped, so that the water outlet pipe 15 and the water inlet pipe 14 are arranged parallel or perpendicularly; however, in actual implementation, this can be varied depending on the usage conditions and is not a limitation.

[0086] Furthermore, the heat dissipation fin assembly 20 includes a first fin assembly 21 disposed in the first cooling section 11 and a second fin assembly 22 disposed in the second cooling section 12. The first fin assembly 21 includes a plurality of first fins 211 disposed in parallel and at intervals. The first fin assembly 21 has a first extension line 210 parallel to the extension direction of the first fins 211, and the first extension line 210 is substantially parallel to the water entry direction 1100.

[0087] In this embodiment, the first fin group 21 includes a first sub-fin group 21a and a second sub-fin group 21b. The first sub-fin group 21a and the second sub-fin group 21b are arranged side by side and staggered to have a step surface 200. In actual use, the first fin group 21 may be a single fin group integrally formed and does not have a step surface 200.

[0088] Furthermore, the second fin group 22 includes a plurality of parallel and spaced-apart second fins 221. The second fin group 22 has a second extension line 220 parallel to the extension direction of the second fins 221, and the second extension line 220 is set at a first angle A with the water outlet direction 1200. Moreover, the angle A of the first angle can be adjusted according to the actual use conditions.

[0089] Specifically, the heat dissipation fin assembly 20 includes a third fin assembly 23 disposed downstream of the first fin assembly 21. The third fin assembly 23 includes a plurality of parallel and spaced-apart third fins 231. The third fin assembly 23 has a third extension line 230 parallel to the extension direction of the third fins 231, and the third extension line 230 is set at a second angle B with the water inlet direction 1100. Furthermore, the angle B of this second angle can be adjusted according to the actual usage conditions.

[0090] Furthermore, the heat dissipation fin assembly 20 includes a fourth fin assembly 24 disposed upstream of the second fin assembly 22. The fourth fin assembly 24 includes a plurality of fourth fins 241 arranged in parallel and at intervals. The fourth fin assembly 24 has a fourth extension line 240 parallel to the extension direction of the fourth fins 241, and the fourth extension line 240 is arranged at a third angle C with the water outlet direction 1200. Moreover, the angle C of this third angle can be adjusted according to the actual usage conditions.

[0091] It is worth noting that the second fin group 22, the third fin group 23, and the fourth fin group 24 each maintain a gap 201 of unequal size with the inner wall surface of the inner cavity 100. Furthermore, the first included angle A, the second included angle B, and the third included angle C are each an acute angle.

[0092] Please refer to another source. Figure 5 and Figure 6 The figures below are schematic diagrams illustrating the application of the water-cooled plate assembly in this invention. The water-cooled plate assembly 1 of this invention can dissipate heat from multiple heat-generating elements 2, and the heat-generating elements 2 can be attached to two opposing outer surfaces of the housing 10. The heat from the heat-generating elements 2 can be conducted through the housing 10 to the heat dissipation fin assembly 20 in the inner cavity 100. Furthermore, the housing 10 is provided with a water inlet pipe 14 and a water outlet pipe 15. The heat dissipation fin assembly 20 includes a first fin assembly 21, a second fin assembly 22, a third fin assembly 23, and a fourth fin assembly 24. Accordingly, the coolant flowing into the housing 10 will exchange heat with the heat dissipation fin assembly 20, thereby carrying away the heat from the heat dissipation fin assembly 20 to achieve the effect of continuously dissipating heat from the heat-generating elements 2.

[0093] In this embodiment, a plurality of heating elements 2 are attached to the upper and lower surfaces of the housing 10. Furthermore, the positions of these heating elements 2 on the housing 10 roughly correspond to the outer surfaces of the heat dissipation fin assemblies 20 projected onto the housing 10, in order to shorten the conduction distance and improve the heat dissipation efficiency.

[0094] Please refer to Figures 7 to 9 , respectively Figure 5 Cross-sectional views along lines 7-7, 8-8, and 9-9. The internal chamber 100 of this invention includes a first chamber 100a located in the first cooling section 11, a second chamber 100b located in the second cooling section 12, and a third chamber 100c located in the third cooling section 13. The first chamber 100a is provided with a first fin group 21. The second chamber 100b is provided with a second fin group 22. The third chamber 100c is provided with a third fin group 23 and a fourth fin group 24.

[0095] Please refer to the above. Figure 5 and Figure 7The housing 10 of this invention includes a guide ramp 16 disposed on the first cooling section 11. The guide ramp 16 is disposed in the first chamber 100a and located on an upstream side of the first fin assembly 21. Accordingly, coolant flowing into the first chamber 100a from the inlet pipe 14 flows along the guide ramp 16 into the first fin assembly 21 to exchange heat with the first fin assembly 21 and remove some of the heat. Then, the coolant flows out of the first fin assembly 21 and enters the third fin assembly 23, where it exchanges heat with the third fin assembly 23 and removes some of the heat.

[0096] Please refer to the above. Figure 5 and Figure 8 In this case, the third chamber 100c of the shell 10 is located in the third cooling section 13, and the third fin group 23 and the fourth fin group 24 are spaced apart in the third chamber 100c. The third fin group 23 is arranged at a second angle B with the water inlet direction 1100, and the fourth fin group 24 is arranged at a third angle C with the water outlet direction 1200 (see reference). Figure 4 Furthermore, after the coolant flows out from the third fin group 23, most of it flows into the fourth fin group 24, and then flows out of the third chamber 100c.

[0097] Please refer to the above. Figure 5 and Figure 9 After the coolant flows out of the third fin assembly 23 in the third chamber 100c, it enters the second chamber 100b and flows into the second fin assembly 22, where it exchanges heat with the second fin assembly 22 to remove some of the heat. Finally, it flows out from the outlet pipe 15. Thus, the heat conducted from the heating element 2 to the heat dissipation fin assembly 20 can be carried away by the coolant, thereby achieving the purpose of heat dissipation.

[0098] It should be noted that the overall heights of the first fin group 21, the second fin group 22, the third fin group 23, and the fourth fin group 24 in this case are approximately the same. It is worth noting that the heights of the first chamber 100a and the second chamber 100b are greater than the height of the third chamber 100c. Therefore, when one side of the first fin group 21 is attached to the first chamber 100a, the other side of the first fin group 21 will form a surface similar to the inner wall of the first chamber 100a. Figure 7 The first retention area 100d is shown. Furthermore, when one side of the second fin assembly 22 is attached to the second chamber 100b, the other side of the second fin assembly 22 forms a surface similar to the inner wall of the second chamber 100b. Figure 9 The second retention area 100e is shown. The arrangement of the first retention area 100d and the second retention area 100e can increase the contact area between the coolant and the first fin assembly 21 and the second fin assembly 22, thereby improving heat dissipation efficiency. In addition, in order to maintain a certain spatial height for the second retention area 100e, a spacer 250 can be placed between the second fin assembly 22 and the first shell plate 101.

[0099] Furthermore, Figure 10 for Figure 5 A cross-sectional view along line 10-10 shows the sections of the first chamber 100a and the second chamber 100b at the position of line 10-10. Furthermore, Figure 11 for Figure 5 The cross-sectional view along line 11-11 shows the section of the third chamber 100c at the location of line 11-11.

[0100] Please refer to the above. Figure 5 and Figure 10 The first chamber 100a is provided with a first fin group 21 and has a first cross-sectional area perpendicular to the water flow direction. The second chamber 100b is provided with a second fin group 22 and has a second cross-sectional area perpendicular to the water flow direction. Furthermore, the third chamber 100c is provided with a third fin group 23 and a fourth fin group 24 and has a third cross-sectional area perpendicular to the water flow direction. The first cross-sectional area is larger than the third cross-sectional area, and the third cross-sectional area is larger than the second cross-sectional area. Generally speaking, the internal flow channels of the casing 10 gradually narrow from the first chamber 100a toward the third chamber 100c and the second chamber 100b, thereby reducing water flow resistance and improving the coolant flow rate and heat dissipation efficiency.

[0101] It should be noted that the first fin assembly 21 can be abutted against one of the walls of the first chamber 100a (see Figure 1). Figure 1 The first fin assembly 21 can be suspended in the first chamber 100a (either the first shell plate 101 or the second shell plate 102), leaving a space on the opposite side. Alternatively, the first fin assembly 21 can be configured to abut against the two opposing inner walls (the first shell plate 101 and the second shell plate 102) of the first chamber 100a. Similarly, the second fin assembly 22 can be configured to abut against one of the walls (the first shell plate 101 or the second shell plate 102) of the first chamber 100a or against the two opposing inner walls (the first shell plate 101 and the second shell plate 102) of the second chamber 100b. In actual use, the configuration of the first fin assembly 21 and the second fin assembly 22 can be adjusted according to the usage conditions. Similarly, in order to maintain a certain spatial height in the second retention area 100e, a spacer 250 can be placed between the second fin assembly 22 and the first shell plate 101.

[0102] Please refer to Figure 12 and Figure 13 These are two cross-sectional embodiments of the internal cavity of the shell in this invention. The shell 10 of this invention includes a first shell plate 101 and a second shell plate 102, and the first shell plate 101 and the second shell plate 102 cover each other to form an internal cavity 100. The internal cavity 100 is provided with a fin assembly 20, and there are various embodiments at the location of the fin assembly 20. For example... Figure 12 As shown, the second shell plate 102 of the housing 10 is fitted with a fin assembly 20, and a protrusion 104 for attaching a heating element is formed on its outer surface. Additionally, as... Figure 13 As shown, the second shell plate 102 of the shell 10 is combined with a fin assembly 20, and a groove 105 is formed on the inner wall surface to increase the contact area with the coolant.

[0103] Please refer to another source. Figure 14 and Figure 15 This is another cross-sectional embodiment of the shell cavity in this case. In this embodiment, the shell 10 includes a first shell plate 101 and a second shell plate 102, and the first shell plate 101 and the second shell plate 102 cover each other to form an inner cavity 100. The inner cavity 100 is provided with a fin assembly 20, and there are various embodiments at the position of the fin assembly 20. For example... Figure 14 As shown, the second shell plate 102 of the housing 10 is fitted with a fin assembly 20, and a protrusion 104 for attaching a heating element is formed on its outer surface. Furthermore, the first shell plate 101 of the housing 10 also has a protrusion 106 for attaching a heating element formed on its outer surface. Also, as... Figure 15 As shown, the second shell plate 102 of the housing 10 is fitted with a fin assembly 20, and a protrusion 104 for attaching the heating element is formed on its outer surface. In addition, the first shell plate 101 of the housing 10 has a groove 107 formed on its inner wall surface to increase the contact area with the coolant.

[0104] In this embodiment, the first shell plate 101 and the second shell plate 102 are generally made of aluminum alloy, and the two shell plates are welded together to form the shell 10. The protrusions 104 and 106, in addition to attaching to the heating element, also absorb the gap between the heat dissipation fin assembly and the heating element. Alternatively, for heat conduction considerations, copper alloy can be welded onto the second shell plate 102 to form the protrusion 104, or welded onto the first shell plate 101 to form the protrusion 106. The positions of the protrusions 104 and 106 and the grooves 105 and 107 are not limited, and can correspond to the outer surface of the heat dissipation fin assembly 20 projected onto the shell 10.

[0105] Please refer to again Figure 16 This is a three-dimensional schematic diagram of another embodiment of the heat dissipation fin assembly of this invention. In this embodiment, the water-cooled plate assembly 1 of this invention includes a housing 10 and a heat dissipation fin assembly 20. The heat dissipation fin assembly 20 is disposed within the housing 10. The heat dissipation fin assembly 20 includes a first fin assembly 21' disposed in a first cooling section 11, a second fin assembly 22 disposed in a second cooling section 12, a third fin assembly 23 disposed in a third cooling section 13, and a fourth fin assembly 24 disposed in a third cooling section 13. The difference between this embodiment and the previous embodiment is that the first cooling section 11 may only have a single first fin assembly 21'. It should be noted that the number and position of the heat dissipation fin assemblies 20 can be adjusted according to the usage conditions to achieve the dual requirements of lightweight and efficient heat dissipation.

[0106] The above description is merely a preferred embodiment of this case and is not intended to limit the scope of the claims. Other equivalent variations that utilize the spirit of the patent in this case should all fall within the scope of the claims.
