[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] This embodiment is an angle-adjustable aluminum heat sink.

[0024] like Figures 1-4 As shown, the substrate includes a base plate 1. Fin assemblies 2 are fixedly mounted at equal intervals on the upper outer surface of the base plate 1. The fin assembly 2 includes a limiting block 3, a fin body 4, a mounting hole 5, a fixing seat 6, an arc groove 7, a cylindrical shaft 8, and a connecting shaft 9. The lower outer surface of the fixing seat 6 is fixedly connected to the upper outer surface of the base plate 1.

[0025] The fin assembly 2 consists of two sets of limiting blocks 3, which are fixedly installed on the outer surfaces of both ends of the fixing seat 6. The mounting holes 5 are opened on the upper part of the outer surface of one side of the limiting block 3, and the fixing seat 6 is opened on the upper outer surface of the fixing seat 6. The fin body 4 is fixed on the upper outer surface of the cylindrical shaft 8, and the connecting shaft 9 is fixedly installed on the outer surfaces of both ends of the cylindrical shaft 8. The connecting shaft 9 is installed in the mounting holes 5, and a damping bearing is provided between the connecting shaft 9 and the limiting block 3. The connecting shaft 9 is rotatably connected to the limiting block 3 through the damping bearing. The cylindrical shaft 8 is rotatably installed in the arc groove 7, and the upper part of the fixing seat 6 is in contact with the outer wall of the cylindrical shaft 8. The substrate 1 and the fin assembly 2 are both made of copper.

[0026] It should be noted that this utility model is an angle-adjustable aluminum heat sink. The fin assembly 2 and the fixing seat 6 are fixed to the upper outer surface of the substrate 1. When the angle of the fin body 4 needs to be adjusted, the fin body 4 only needs to be flipped. The fin body 4 drives the cylindrical shaft 8 to rotate, and the cylindrical shaft 8 drives the connecting shaft 9 to rotate. The connecting shaft 9 is installed in the mounting hole 5 through the damping bearing, so that the angle of the fin body 4 is easy to adjust. The cylindrical shaft 8 is in the arc groove 7 on the upper part of the fixing seat 6 and can rotate. The cylindrical shaft 8 is located in the arc groove 7, and the fixing seat 6 contacts the outer wall of the cylindrical shaft 8 through the arc groove 7, which facilitates the transfer of heat.
