[0031] This embodiment provides a water-cooled radiator, such as Figure 1-Figure 7 As shown, it includes a base 1 and a plurality of fins 2. A receiving cavity is provided in the base 1. The plurality of fins 2 are arranged in parallel in the receiving cavity. The bottom sides of the plurality of fins 2 are connected to the base 1 and the base 1 is an integrated structure. A gap is provided between two adjacent fins 2 to form a heat exchange channel 21 for passing a fluid.
[0032] The fin 2 and the base 1 in this embodiment are an integrated structure. The fin is cut out by an integrated wire, has good strength, does not need tempering treatment, and does not damage the hardness of the fin, so that the fin has good pressure bearing strength and can withstand greater water pressure, so that the fluid can withstand a greater flow rate when flowing through the fin, and instantly takes away more heat, achieving a better heat dissipation effect. Modular design, faster processing, more cost-saving, high yield, saving design time.
[0033] As a preferred embodiment, the thickness of the fin 2 is equal to the width of the heat exchange channel 21. The fins 2 are arranged evenly and form even heat exchange channels 21, thereby improving the heat exchange efficiency of the fluid.
[0034] As a preferred embodiment, the width of the heat exchange channel 21 is a, 0.15 mm ≤ a ≤ 0.3 mm. a is 0.15 mm, 2 mm or 0.3 mm.
[0035] The water-cooled radiator of this embodiment can be applied to the electronics field to dissipate heat from electrical components. The base 1 is placed against the component that needs heat dissipation, and the heat generated by the component is conducted to the base 1. Since the base 1 and the fins 2 are an integrated structure, the heat of the base 1 can be efficiently conducted to the fins, so that the heat is taken away by the flowing water, thereby efficiently dissipating the heat from the component.
[0036] The width of the heat exchange channel 21 can be adjusted according to the heat exchange requirements to improve the heat exchange efficiency.
[0037] As a preferred embodiment, the fins 2 are vertically arranged in the accommodating cavity, and the water flows into the heat exchange channel 21, reducing the flow resistance and making the water flow smoother.
[0038] As a preferred embodiment, the water-cooled radiator of this embodiment further includes an upper cover 4 and a partition 3. Figure 2 and Figure 7 As shown, the partition 3 covers the base 1 and forms a first cavity 14 between the base 1, the upper cover 4 covers the partition 3 and forms a second cavity 10 between the partition 3, and a water hole 31 connecting the first cavity 14 and the second cavity 10 is provided on the partition 3.

[0041] The water inlet 8 is used to connect the water source, and the heat exchange medium is sent into the first cavity 14. After heat exchange through the fins 2, the heat exchange medium flows into the second cavity 10 from the water hole 31, and then flows out from the water outlets 6 on the left and right sides. A double-layer water path is formed through the first cavity 14 and the second cavity 10, which increases the flow path and the contact area between the water flow and the radiator, so that the water flow heat exchange is more sufficient, takes away more heat, and cools the components more fully.
[0042] As a preferred embodiment, the distances between the two water outlets 6 and the water inlet 8 are equal, so that the flow paths of water on the left and right sides of the water inlet 8 are equivalent, allowing the water to pass quickly, and the water outlet speeds of the two water outlets 6 are equivalent.

[0044] Specifically, the front and rear ends of the support plate 5 are respectively provided with blocks that cooperate with the support groove 13. The blocks protrude from the front and rear sides of the support plate 5. The blocks 52 are correspondingly clamped in the support groove 13 to limit the support plate 5 and prevent it from moving.
[0045] As a preferred implementation mode, Figure 6 As shown, the depth of the support groove 13 is b, 0.2mm≤b≤0.3mm. The length of the block 52 protruding from the front and rear sides of the support plate 5 is equivalent to the depth of the support groove 13, so as to support and position the support plate 5, so that the support plate 5 has better support strength.
[0046] As a preferred embodiment, two support plates 5 are provided, a flow gap 51 is provided between the two support plates 5 , and the bottom end of the water inlet 8 is connected to the middle of the partition plate 3 and is provided directly above the flow gap 51 .
[0047] The water inlet nozzle 8 is correspondingly arranged above the flow gap 51 , so that the water flow entering through the water inlet nozzle 8 flows through the flow gap 51 to the lower side of the support plate 5 and exchanges heat with the fins in the first cavity.
[0048] The first flow channel 11 and the second flow channel 12 are respectively arranged on the left and right sides of the first cavity 14 . The first flow channel 11 and the second flow channel 12 are respectively located at the left and right ends of the fin 2 . Two water holes 31 are arranged, and the two water holes 31 are respectively arranged above the first flow channel 11 and the second flow channel 12 .

The water in the first flow channel 11 and the second flow channel 12 flows upward to the second cavity 10 through the two water holes 31 on the partition 3.
[0050] The water-cooled radiator of this embodiment further includes a plurality of positioning pins 9. The upper cover 4, the partition plate 3 and the support plate 5 are respectively provided with a first connection hole, a second connection hole and a third connection hole, which are arranged correspondingly up and down. The positioning pins 9 pass through the first connection hole, the second connection hole and the third connection hole in sequence and are welded to the upper cover 4, the partition plate 3 and the support plate 5. The positioning pins are welded and sealed to make the structure stronger and able to withstand greater water pressure.
[0051] A sealing ring 7 is arranged on the upper side of the upper cover 4 , and a water inlet 8 and a water outlet 6 are respectively arranged through the sealing ring 7 .
