Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0018] Please see Figure 1 This is a three-dimensional combined schematic diagram of the first embodiment of the present invention. The present invention provides a multi-layer liquid cooling head structure C, which is used to connect to a liquid cooling heat dissipation system (not shown) and inject coolant (not shown) for heat exchange, and then return the coolant to the cooling system for recycling; the multi-layer liquid cooling head structure C includes a first shell component 1, a second shell component 2, and a separating component disposed between the first shell component 1 and the second shell component 2; wherein: like Figure 2 and Figure 3 As shown, the first shell component 1 can be made of a thermally conductive material such as copper or aluminum, and has a first plate portion 10 for attaching to a heat source (not shown) for heat dissipation. The first plate portion 10 has two or more fin channel groups 11, each fin channel group 11 consisting of two or more fins 110. Each fin channel group 11 is arranged in two rows, forming a main channel 12 between the two rows. The forming direction of the fins 110 in each fin channel group 11 intersects with the main channel 12, so that the spacing between the fins 110 serves as a branch channel of the main channel 12. Furthermore, there is a gap d between adjacent fin channel groups 11.

[0019] As described above, the second shell component 2 can also be made of a thermally conductive material such as copper or aluminum, and has a second plate portion 20 to cover each of the fin channel assemblies 11 of the first shell component 1, forming a sealed hollow cavity between the second plate portion 20 and the first plate portion 10, so that the partition component 3 can be disposed therein. In the embodiment of this utility model, the partition component 3 has a partition plate portion 30 and an annular side portion 31 surrounding the partition plate portion 30. The partition plate portion 30 is located between the first plate portion 10 and the second plate portion 20, and the annular side portion 31 is sealed to the outer periphery between the first plate portion 10 and the second plate portion 20, so that the hollow cavity is formed in the annular side portion 31, the first plate portion 10 and the second plate portion 20.

[0020] like Figure 2 and Figure 4 As shown, a first merging area A1 and a second merging area A2 are separated between the partition plate portion 30 and the second plate portion 20. In the embodiment of this utility model, the first merging area A1 and the second merging area A2 are separated by a frame rib 32, which is located between the second plate portion 20 and the partition plate portion 30. Two or more support columns 33 located within the first merging area A1 or the second merging area A2 can be provided between the second plate portion 20 and the partition plate portion 30. Each of the support columns 33 abuts against the inner surface of the second plate portion 20 and the partition plate portion 30 to maintain the formation of the first merging area A1 or the second merging area A2.

[0021] like Figure 3 and Figure 5 As shown, the partition plate 30 and the first plate 10 are used to accommodate the aforementioned fin channel groups 11. That is, the partition plate 30 is attached to each of the fin channel groups 11, and a return port 310 is provided on the outer side of each row of fin channel groups 11 corresponding to the partition plate 30. An injection port 320 is provided at the corresponding main channel 12. The injection port 320 is connected to the first confluence area A1, and each of the return ports 310 is connected to the second confluence area A2. In the embodiment of this utility model, two or more support ribs 300 are provided between the first plate portion 10 and the partition plate portion 30, and each support rib 300 provides support within the gap d between adjacent fin channel groups 11. Further, each support rib 300 can protrude from a surface of the partition plate portion 30 relative to the first plate portion 10, and after being inserted into the gap d, it can be welded to the inner surface of the first plate portion 10. The welding can be laser welding or spot welding, etc. In addition, the partition plate portion 30 can have two or more grooves 301 formed in a single direction on the surface of the partition plate portion 30 relative to the first plate portion 10, and the grooves 301 are staggered in contact with the upper edge of the fins 110 of each fin channel group 11.

[0022] Therefore, by using the above-described structure, the multi-layer liquid cooling head structure of this utility model can be obtained.

[0023] Accordingly, Figure 6 As shown, this utility model can deliver coolant into the multi-layer liquid cooling head structure C for heat exchange through connection with the aforementioned liquid cooling system. Figure 1 and Figure 6 As shown, the present invention provides a water inlet connector 21 and a water outlet connector 22 on the second plate portion 20 of the second shell component 2, so that the liquid cooling system can inject coolant through the water inlet connector 21. The water inlet connector 21 is connected to the first confluence area A1 through the second plate portion 20 via a water inlet 210, so that the coolant, after accumulating in the first confluence area A1, impacts the main channel 12 through the inlet 320 and passes through the two rows of finned flow channel groups 11 respectively, so as to effectively perform heat exchange. Then, it is collected in the second confluence area A2 through the return port 310, and the water outlet connector 22 is connected to the second confluence area A2 through the second plate portion 20 via a water outlet 220. Therefore, the coolant after heat exchange can be sent back to the liquid cooling system for cooling and temperature reduction through the water outlet connector 22. In this way, by distributing the coolant in a stratified manner, the coolant can achieve a more uniform temperature during heat exchange, thereby effectively improving its heat exchange efficiency.

[0024] Please see again Figure 7 The image shows a second embodiment of this utility model. It can be further modified by adding an inlet water connector 23 and an outlet water connector 24 to the second plate portion 20, thereby enabling connection to other water cooling heads C1 to provide different heat sources for heat dissipation. For example... Figure 8 As shown, the water-cooling head C1 includes a hollow plate 4, and a second water outlet connector 40 and a second water inlet connector 41 disposed on the hollow plate 4 and communicating with the interior of the hollow plate 4. The second water outlet connector 40 is directly or indirectly connected to the branch water inlet connector 23 via a pipe, and the second water inlet connector 41 is also directly or indirectly connected to the branch water outlet connector 24 via a pipe. The water inlet connector 21 and the water outlet connector 22 are respectively used to connect to an inlet end A and an outlet end B of the liquid cooling system for coolant circulation. In this way, it can also be further used as a branch to connect more water-cooling heads C1 to provide different heat sources for heat dissipation.

Equivalent substitutions or modifications made by those skilled in the art based on the present utility model, or reasonable combinations of features and solutions from various embodiments, are all within the protection scope of the present utility model.
