[0024] The cross-sectional shape of the mounting groove 5 is U-shaped, and the left and right ends of the mounting groove 5 extend to the left and right sides of the liquid cooling plate body 1 respectively. Adhesive is filled between the mounting groove 5 and the pipe 3. The mounting groove 5 is opened on the front of the liquid cooling plate body 1, and the pipe 3 is installed by embedding. Then, the adhesive can be filled in the gap between the pipe 3 and the mounting groove 5 to improve the bonding strength, so that the pipe 3 is not easy to fall off, and the thermal resistance of thermal conductivity is low.

[0025] See also Figure 3 In order to achieve the sealing characteristic and facilitate the disassembly of the external connection pipe, the sealing mechanism 2 in this embodiment includes a connection seat 201 fixed on the left side of the liquid cooling plate body 1, a sealing ring 202 is fixed on the right side wall of the inner cavity of the connection seat 201, and a threaded groove 203 is opened on the inner wall of the inner cavity of the connection seat 201.

[0026] In this example, there are two sealing mechanisms 2. The right sealing mechanism 2 is arranged at the connection between the right end of the pipe 3 and the liquid cooling plate body 1. The shape of the connecting seat 201 is a hollow cylinder with the left side missing. The sealing ring 202 is movably fitted with the inner bottom wall of the inner cavity of the connecting seat 201. When the external connecting pipe is connected to the connecting seat 201, the external connecting pipe and the connecting seat 201 are threadedly connected so that the connecting pipe is in contact with the sealing ring 202 to achieve the characteristic of sealing, so that the liquid can pass through the pipe 3 for heat conduction.

[0027] It should be noted that the pipe 3 is installed by embedding, and then the adhesive can be filled in the gap between the pipe 3 and the installation groove 5 to improve the bonding strength, so that the pipe 3 is not easy to fall off, and the thermal resistance of heat conduction is low. The external connecting pipe is threadedly connected to the connecting seat 201, so that the connecting pipe is in contact with the sealing ring 202 to achieve the characteristic of sealing, so that the liquid can pass through the pipe 3 for heat conduction.

[0032] The working principle of the above embodiment is:

Then, an adhesive can be filled in the gap between the pipe 3 and the mounting groove 5 to improve the bonding strength, so that the pipe 3 is not easy to fall off, and the thermal resistance of the heat conduction is low. At the same time, when the external connecting pipe is connected to the connecting seat 201, the external connecting pipe and the connecting seat 201 are threadedly connected, so that the connecting pipe is in contact with the sealing ring 202 to achieve the characteristic of sealing, so that the liquid can pass through the pipe 3 for heat conduction.

[0034] (2) Due to the composition of the various materials in the heat-conducting component 4, the heat-conducting insulating silicone grease composition of the heat transfer layer 401 makes the liquid cooling plate body 1 have excellent thermal conductivity and good electrical insulation. The graphene film composition of the heat-conducting layer 402 makes the liquid cooling plate body 1 have the characteristics of high flexibility and strong thermal conductivity. The aluminum oxide coating composition of the insulating layer 403 can maintain good electrical insulation performance under high temperature conditions. The heat-conducting silicone sheet composition of the conductive layer 404 can effectively improve the heat transfer efficiency and also play an insulating role.
