Fins 2 for heat dissipation are arranged in the base 1, and a receiving cavity is provided in the base 1. The fins 2 are arranged in the receiving cavity, and the top of the base is an open structure.

[0032] The partition 3 is covered on the base 1 and forms a first cavity 11 between the base 1, and the upper cover 4 is covered on the partition 3 and forms a second cavity 6 between the partition 3. The water flow can flow from the first cavity 11 into the second cavity 6 or from the second cavity 6 into the first cavity 11. The water flow can first enter the first cavity 11 to exchange heat with the fins 2, and then flow into the second cavity 6 to take away more heat before flowing out of the radiator. Alternatively, the cooling water can first enter the second cavity 6 to take away the heat on the partition 3, and then enter the first cavity to further contact with the fins for heat dissipation before flowing out of the radiator.

[0033] The base 1, the fins 2, the partition 3 and the upper cover 4 may be made of aluminum alloy or other materials with high thermal conductivity.

[0034] When the double-layer water-cooled radiator of this embodiment is in use, the base 1 is attached to the component that needs heat dissipation, and the heat emitted by the component is conducted to the base and the fins. When the water flows through the fins 2, heat exchange is generated, thereby dissipating the heat and cooling the component.

[0035] The double-layer water-cooled radiator in this embodiment forms a double-layer water path by setting a first cavity 11 and a second cavity 6, and the second cavity 6 is set on the upper side of the first cavity 11. The internal arrangement is compact, which increases the contact area between the flow path and the water flow and the radiator, making the water flow heat exchange more sufficient, taking away more heat, and cooling the components more fully.

[0036] As a preferred implementation mode, Figure 2 and Figure 6 As shown, an upper water inlet 41 and an upper water outlet 42 are provided on the upper cover 4.

[0039] In this embodiment, the water flows into the first cavity 11 from the middle, flows to the left and right sides in the first cavity 11, and after the heat exchange effect of the fins 2, enters the second cavity 6 from the left and right lower water outlets 32 of the partition. The water flows in the second cavity and further contacts the partition and the upper cover for heat exchange before flowing out from the upper water outlet 42 of the upper cover 4, further increasing the flow path of the water flow in the heat exchanger, so that the heat exchange effect is better.

[0040] As a preferred embodiment of the present invention, Figure 2 As shown, the double-layer water-cooled radiator in this embodiment also includes a water inlet 7 and a water outlet 8. The water inlet 7 is connected to the lower water inlet 31 and the upper water inlet 41 and is arranged to pass through the upper water inlet 41, and the water outlet 8 is connected to the upper water inlet 41. The axes of the water inlet 7 and the water outlet 8 are both perpendicular to the upper cover. The water inlet 7 introduces the water flow into the first cavity 11. The water outlet 8 leads the water flow in the second cavity 6 out of the radiator. Specifically, the water inlet 7 should be connected with the lower water inlet 31 and the upper water inlet 41 by an interference fit, or a sealing ring should be provided to enable the mouth position to be sealed.

[0041] As a preferred embodiment of the present invention, Figure 5 As shown, upper side edges 34 protruding upward are provided on both the front and rear sides of the partition 3, and the cross section of the partition 3 in the front and rear directions forms a U-shaped structure with an opening facing upward.

[0042] The upper cover 4 is provided with lower side edges 44 protruding downwards on both the front and rear sides, and the two lower side edges 44 are respectively clamped on the inner sides of the two upper side edges 34. The cross section of the upper cover 4 in the front and rear directions forms a U-shaped structure with an opening downwards.

[0043] The lower side edge 44 of the upper cover 4 abuts against the inner side surface of the partition 3 , and the lower side edge 44 is tightly connected to the upper side edge 34 , and the connection is firm.

[0044] In this embodiment, the lower side 44 and the upper side 34 are engaged with each other and a seal is formed at the engaging position, so that a second cavity is formed between the partition plate 3 and the upper cover 4 for water to flow through.

[0045] As a preferred embodiment of the present invention, Figure 6 As shown, the left and right sides of the base 1 are respectively provided with side plates 14 extending upward, and the side plates 14 are installed on the left and right sides of the first cavity 11. Figure 4 As shown, the top surface of the side plate 14 is flush with the top surface of the upper cover.

[0046] The upper side edges 34 extend to the left and right sides of the partition 3 , and the side plate 14 is clamped between the two upper side edges 34 and tightly connected to the two upper side edges 34 , so that the base 1 , the partition and the cover plate are firmly connected.

[0047] like Figure 6 As shown, the top view of the base 1 can be square or rectangular, or circular or other shapes, which are not specifically limited here.

[0048] As a preferred solution of the utility model, the double-layer water-cooled radiator in this embodiment also includes a support plate 5, and the fin 2 is extended in the base 1 along the left and right directions. Support grooves 15 with openings facing the fins 2 are respectively provided on the front and rear sides of the base 1, and the support plate 5 is provided on the upper side of the fin 2 and its two ends are overlapped on the support groove 15. The partition 3 is arranged closely on the upper side of the support plate 5. The support groove 15 supports the support plate 5 to prevent the support plate 5 from squeezing the fins. By providing the support plate 5, the pressure bearing capacity of the fin 2 is improved, and it can withstand 20kg water pressure.

[0049] In order to avoid the lower water inlet 31 being blocked by the setting of the support plate 5, two support plates 5 are provided, and a flow gap 52 is provided between the two support plates 5. The lower water inlet 31 is correspondingly arranged above the flow gap 52, so that the water flow entering from the lower water inlet 31 passes through the flow gap 52 and then flows to the lower side of the support plate 5, and exchanges heat with the fins in the first cavity.

[0050] As a preferred solution of the utility model, a first flow channel 12 and a second flow channel 13 are respectively arranged on the left and right sides of the first cavity 11, the first flow channel 12 and the second flow channel 13 are respectively located at the left and right ends of the fin 2, and the lower water outlet 32 ​​on the partition 3 is respectively arranged above the first flow channel 12 and the second flow channel 13.

[0051] In this embodiment, water flows into the middle of the fin 2 from the lower water inlet 31, and flows from the middle to the left and right sides. After heat exchange through the fins, it flows to the first flow channel 12 and the second flow channel 13 respectively. The water in the first flow channel 12 and the second flow channel 13 flows upward through the lower water outlet 32 ​​on the partition 3 to the second cavity 6.

The first connection hole 43, the second connection hole 33 and the third connection hole 51 are circular through holes.

[0053] The positioning pin 10 passes through the first connection hole 43 , the second connection hole 33 and the third connection hole 51 in sequence and is welded to the upper cover 4 , the partition plate 3 and the support plate 5 .

[0054] The positioning pins in this embodiment are welded and sealed, making the structure stronger and able to withstand greater water pressure. This increases the flow rate of the enclosed liquid, instantly taking away more heat and achieving a better heat dissipation effect. When the fluid passes through the second cavity 6, it contacts the positioning pins and can further take away more heat.

[0055] As a preferred solution of the utility model, a sealing ring 9 is provided on the upper side of the upper cover 4, which is respectively provided corresponding to the upper water inlet and the upper water outlet 42, and the water inlet nozzle 7 and the water outlet nozzle 8 are respectively provided through the sealing ring 9.
