[0030] The water cooling plate 100 is provided with a copper tube 110, which is distributed in a curved shape at the water cooling plate 100.

[0031] A copper tube 110 is disposed in the water cooling plate 100 . The copper tube 110 has a first liquid inlet hole 111 and a first reflux hole 112 .

[0032] Specifically, the water-cooling plate 100 is in the shape of a plate, and the copper tube 110 is installed in the water-cooling plate 100. The installation method can be that the copper tube 110 is pre-buried in the water-cooling plate 100 as a whole, or a groove 103 is opened on the surface of the water-cooling plate 100, and the copper tube 110 is installed in the groove 103 and exposed on the surface of the water-cooling plate 100; and if the whole pre-buried method is adopted, it is necessary to manufacture the water-cooling plate 100 and the copper tube 110 as a whole when manufacturing the water-cooling plate 100; and if the groove 103 is opened on the surface of the water-cooling plate 100, the water-cooling plate 100 and the copper tube 110 are manufactured independently, and then the groove 103 is opened on the surface of the water-cooling plate 100, and then the copper tube 110 is pressed into the groove 103, and the process is simple;

[0033] In order to improve the aesthetics and flatness of the product, when the copper tube 110 is pressed tightly against the groove 103, the surface of the copper tube 110 exposed in the groove 103 is flattened. At the same time, if there is a gap between the groove 103 and the copper tube 110, a glue filling operation is performed to ensure that the groove 103 is filled;

[0034] Optionally, the glue filling operation uses thermal conductive glue.

[0035] Furthermore, in order to enhance the heat transfer performance, the copper tube 110 is distributed in a curve at the water cooling plate 100, such as Figure 2 As shown, Figure 2 The middle dotted line L is a partition, from the first liquid inlet hole 111 to the dotted line L is the first pipe section, and from the dotted line L to the first reflux hole 112 is the second pipe section.

[0040] The fluid channel 230 includes: two flow channels A231 arranged in the first component 210 and a flow channel B232 arranged in the second component 220; the two flow channels A231 are connected through the flow channel B232; when the fluid flows in the fluid channel 230, it enters the first flow channel A231 from the second liquid inlet hole 201, then enters the flow channel B232, then enters the second flow channel A231, and finally flows out from the second return hole 202, and performs heat exchange with the optical fiber head 200 during the flow process;

[0041] Furthermore, the first component 210 is horizontally disposed, and the second component 220 is vertically disposed on the first component 210 , thereby forming a three-dimensional heat dissipation effect.

[0042] The flow channel B232 is arranged in a curve, and openings 2321 are arranged at the top and bottom of the second component 220. The flow channel B232 is connected to the openings 2321, and a cover plate 240 is arranged at the opening 2321; the second component 220 is arranged in a ring shape, and the flow channel B232 is arranged in a curve in the second component 220, and the fluid flows back and forth in the flow channel B232 in the direction away from the first component 210 and close to the first component 210.

[0043] like Figure 6-7 As shown, the flow channel B232 is distributed in the second component 220 in an up-and-down direction, and the openings 2321 at the top and bottom of the second component 220 are for facilitating the opening of the fluid channel 230 at the optical fiber head 200 during the manufacturing process.
