Description

Technical Field

[0001] This utility model relates to a water-cooled or liquid-cooled heat dissipation system, and more particularly to a shunt-type liquid cooling head device. Background Technology

[0002] Existing liquid cooling systems are commonly used for heat dissipation of high-power electronic components or processors. They typically include a circulation loop with at least one water block, through which coolant flows to exchange heat with the heat source, such as the electronic component. In practical designs, liquid cooling systems often utilize a single water block directly attached to a single heat-generating element to achieve heat dissipation.

[0003] However, with the increasing multi-core and highly integrated nature of computing devices, a single liquid cooling head can no longer meet the needs of multiple high heat flux density components. Therefore, some technologies propose setting multiple liquid cooling heads in the same liquid cooling circuit to address different heat sources and improve heat dissipation efficiency. However, this configuration of at least two liquid cooling heads is typically connected in series in the circulation circuit via piping. Therefore, by the time the coolant passes through the last liquid cooling head, the heat carried by it is no longer available for heat exchange, resulting in a deficiency. Utility Model Content

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 schematic diagram of the present invention. The present invention provides a split-flow liquid cooling head device for connecting to a liquid cooling system (not shown). Coolant (not shown) is injected into the liquid cooling system through an inlet A, and after heat exchange with the coolant through the split-flow liquid cooling head device, the coolant is returned to the cooling system through an outlet B for recycling. The split-flow liquid cooling head device includes a first liquid cooling unit C1 and at least one second liquid cooling unit C2; wherein: like Figure 2 and Figure 3As shown, the first liquid cooling unit C1 includes a first shell component 1, a second shell component 2, and a partition component 3 disposed between the first shell component 1 and the second shell component 2. The first shell component 1 may 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 is provided with at least two fin channel groups 11, each fin channel group 11 consisting of at least two fins 110, and 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 of each fin channel group 11 intersects with the main channel 12, so that the spacing between each fin 110 can serve as a branch channel of the main channel 12. In addition, 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 confluence area A1 and a second confluence 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 confluence area A1 and the second confluence area A2 are separated by a frame rib 32, which is disposed between the second plate portion 20 and the partition plate portion 30. At least two first support columns 33 located in the first confluence area A1 and at least two second support columns 34 located in the second confluence area A2 are provided between the second plate portion 20 and the partition plate portion 30. The first support columns 33 abut against the inner surface of the second plate portion 20 and the partition plate portion 30 to maintain the formation of the first confluence area A1; and the second support columns 34 abut against the inner surface of the second plate portion 20 and the partition plate portion 30 to maintain the formation of the second confluence area A2.

[0021] like Figure 3 and Figure 5As shown, the partition plate portion 30 and the first plate portion 10 are used to accommodate the aforementioned fin channel groups 11. A return port 310 is provided on the partition plate portion 30 at the outer side of each row of fin channel groups 11, and 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, at least two support ribs 300 are provided between the first plate portion 10 and the partition plate portion 30, and each support rib 300 corresponds to 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 is welded to the inner surface of the first plate portion 10. The welding can be laser welding or spot welding, etc. Furthermore, the partition plate portion 30 may be provided with at least two grooves 301 formed in a single direction on the surface of 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 assembly 11.

[0022] Please see again Figure 1 and Figure 6 As shown, the second liquid cooling unit C2 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. A first water inlet connector 21 and a first water outlet connector 22 are provided on the second plate portion 20 of the first liquid cooling unit C1. The second water outlet connector 40 is directly or indirectly connected to the first water inlet connector 21 via a pipe, and the second water inlet connector 41 is also directly or indirectly connected to the first water outlet connector 22 via a pipe. See also... Figure 3 and Figure 4 As shown, the first water inlet connector 21 is connected to the first confluence area A1 through the second plate portion 20 via a first water inlet 210, and the first water outlet connector 22 is connected to the second confluence area A2 through the second plate portion 20 via a first water outlet 220.

[0023] Therefore, the shunt liquid cooling head device of this utility model can be obtained by using the above-described structure.

[0024] Accordingly, Figure 1 and Figure 6 As shown, the present invention further includes a main water inlet connector 23 and a main water outlet connector 24 on the second shell component 2 of the first liquid cooling unit C1. The main water inlet connector 23 is connected to the water inlet A of the liquid cooling heat dissipation system for coolant injection, and the main water outlet connector 24 is connected to the water outlet B for coolant discharge; similarly, as Figure 3 and 4As shown, the main water inlet connector 23 is connected to the first confluence area A1 via a main water inlet 230 through the second plate portion 20, and the main water outlet connector 24 is connected to the second confluence area A2 via a main water outlet 240 through the second plate portion 20. Therefore, it can be as follows... Figure 6 As shown, coolant is sent to the first liquid cooling unit C1 through the inlet A, and after entering through its main inlet connector 23, it gathers in the first confluence area A1. Then, it flows through the injection port 320 towards the main channel 12 and passes through the two rows of finned flow channels 11 to effectively exchange heat within the first liquid cooling unit C1. Next, it gathers in the second confluence area A2 through the return port 310. A portion of the coolant can be sent to the second liquid cooling unit C2 through the first outlet connector 22, and a portion of the coolant can be sent back to the liquid cooling heat dissipation system for cooling and temperature reduction through the main outlet connector 24 connected to the outlet B. Among them, a portion of the coolant sent to the second liquid cooling unit C2 can enter the hollow plate 4 through its second inlet connector 41 for heat exchange, and then return to the first liquid cooling unit C1 through its second outlet connector 40. The coolant returning to the first liquid cooling unit C1 can be collected again at the first confluence area A1 through its first water inlet 21 to achieve a uniform temperature. In this way, by distributing the coolant as described above, its heat exchange efficiency can be made more consistent and average.
