Detailed Description

As shown in fig. 1-3, the heat sink profile of the present embodiment includes a base plate 1 and fins 2 that are integrally formed. The substrate 1 comprises a fin connecting surface 1-1 and a heating element contact surface 1-2. A group of fins 2 is arranged on the fin connecting surface 1-1 of the substrate 1. The fins 2 are arranged in a convex structure, and the height of the fin 2 in the middle is greater than that of the fins 2 on the two sides. Because of the difference of the height of the fins 2, which areas adopt the higher fins 2 are related to the area of the heating element and the external structural element, the areas corresponding to the heating element adopt the higher fins 2, the areas easy to contact with the external structural element adopt the lower fins 2, and the laying area ratio of the middle fins 2 and the fins 2 at the two sides is preferably 2: 1: 1, the height ratio of the middle fin 2 to the two side fins 2 is 2: 1: 1. threaded holes 1-4 are formed in the contact surface 1-2 of the heating element of the substrate 1, and the heating element is fixed with the substrate 1 through the threaded holes 1-4.

In order to avoid collision between the fins 2 and the outside, the side surface of the substrate 1 preferably has a baffle 1-3, and the baffle 1-3 overlaps the outermost fin 2 and extends toward the contact surface 1-2 of the heating element. The baffle 1-3 of the present embodiment has an area twice that of the fin 2, and is disposed on one side of the substrate 1, or symmetrically disposed on two sides of the substrate 1 according to actual requirements.

For make things convenient for radiator section bar to accurately install on the circuit board, the preferred reference column 3 that still includes of this embodiment, reference column 3 is the bar copper, and the surface is plated fog tin, and radiator section bar accessible reference column 3 and circuit board welded fastening. The heating element contact surface 1-2 of the substrate 1 is provided with built-in positioning column mounting holes 1-5, the axis direction of the positioning column mounting holes 1-5 is parallel to the fins 2, the positioning column 3 is inserted into the positioning column mounting holes 1-5 through interference fit, and after the mounting is finished, the positioning column 3 and the fins 2 are respectively arranged on two sides of the substrate 1. A group of positioning columns 3 of the present embodiment are arranged on the contact surface 1-2 of the heating element along the diagonal direction.

Because the substrate 1 is thin, in order to prevent the positioning post 3 from interfering with the fin 2 during the installation process and causing damage, as shown in fig. 4, the contact end of the fin 2 and the substrate 1 in the preferred embodiment is provided with a positioning post slot 2-1, and one end of the positioning post 3 passes through the positioning post mounting hole 1-5 of the substrate 1 and is inserted into the positioning post slot 2-1 of the fin 2. Through the positioning column slot 2-1 with enough space reserved on the fin 2, one end of the positioning column 3 is inserted into the fin 2, so that structural interference is avoided, the positioning column 3 is inserted deeper, and the installation firmness is improved.
