Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Those skilled in the art will appreciate that the features of the various embodiments can be combined with features of other embodiments in any manner within the scope of the application. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0035] The application will be described with reference to the accompanying drawings, of which: Figure 1 to the accompanying drawings, Figure 11 A heat sink is described.

[0036] At present, the existing heat sink is fixed by multiple parts, and when the heat pipe flows to the heat sink, the heat insulation effect will inevitably affect the heat conduction efficiency and cause adverse effects on the heat dissipation process of the heat sink.

[0037] Therefore, the heat sink comprises a heat transfer assembly 3 and multiple heat dissipation fins 11. The heat transfer assembly 3 is connected to a heat dissipation component, and the heat transfer assembly 3 is provided with a heat-conducting liquid. The heat dissipation fins 11 are integrally formed with heat dissipation grooves 21. The heat dissipation grooves 21 are sequentially connected to form a heat dissipation channel 2. The heat dissipation channel 2 is provided for the heat-conducting liquid to flow through. The first direction A end of the heat dissipation channel 2 is in communication with the heat transfer assembly 3, so that the heat carried by the heat-conducting liquid is transmitted to the heat dissipation fins 11 through the heat dissipation channel 2.

[0038] After the heat sink is connected, the heat-conducting liquid is placed in the heat transfer assembly through the second direction B end of the heat dissipation channel, and then the second direction B end of the heat dissipation channel is sealed.

[0039] The heat dissipation channel 2 is integrally formed with the heat dissipation fins 11, which eliminates the heat insulation effect, so that the heat can be efficiently conducted from the heat-conducting liquid in the heat pipe to the fins through the heat dissipation fins, thereby improving the heat dissipation efficiency of the heat sink. In addition, the heat sink can be made of aluminum material, which greatly saves the cost compared with the copper material in the prior art.

[0040] In order to integrally form the heat dissipation fins 11 and the heat dissipation grooves 21, different processes can be used for manufacturing. Preferably, a stamping process is used. Specifically, corresponding heat dissipation grooves 21 are opened on each heat dissipation fin 11, and the edges of the heat dissipation grooves 21 extend in the first direction A. Through the stamping process, the waste generated by opening holes in the heat dissipation fins 11 is reduced, and this part of waste is converted into the wall surface of the heat dissipation channel 2, thereby saving the material cost. In other embodiments of the application, the edges of the heat dissipation grooves 21 can also extend in the second direction B, as long as the heat dissipation grooves 21 are integrally formed with the heat dissipation fins 11.

[0041] When the heat dissipation grooves 21 are sequentially connected to form the heat dissipation channel 2, the heat dissipation fins 11 are sequentially connected to form a heat dissipation assembly 1. The heat dissipation assembly 1 is composed of multiple heat dissipation fins 11.
