Detailed Description

As shown in fig. 1-3, the aluminum profile heat sink of the present embodiment includes a substrate 1 and fins 2 that are integrally formed. The fins 2 are symmetrically arranged on two sides of the substrate 1, and a group of fins 2 are spread along the substrate 1 in two directions and are uniformly distributed. The ratio of the laying area of the fins 2 to the area of the substrate 1 is less than 1: 1, reserving an installation area of a heating element, arranging a group of threaded holes 1-1 on the bare surface of the substrate 1, and fixing the heating element and the substrate 1 through the threaded holes 1-1. In order to increase the heat dissipation effect, the shape of the side surface of the fin 2 is improved, as shown in fig. 1, the preferred side surface of the fin 2 of the present embodiment is a wave-shaped curved surface; as shown in fig. 7, the side surface of the preferred fin 2 of this embodiment is provided with convex ridges, a wave-shaped curved surface and convex ridges, which can increase the heat dissipation area of the fin 2. For make things convenient for the section bar radiator 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 the section bar radiator passes through reference column 3 and circuit board welded fastening. A side face of the base plate 1 is provided with a built-in positioning column mounting hole 1-2, the axis direction of the positioning column mounting hole 1-2 is perpendicular to the fin 2, and the positioning column 3 is inserted into the positioning column mounting hole 1-2 through interference fit.

The laying position of the fins 2 can be adjusted according to the installation environment of the profile radiator in the product. As shown in fig. 4, the preferred fins 2 of this embodiment are laid on one end of the substrate 1, the outermost fins 2 are overlapped with the end portions 1-3 of the substrate 1, and in order to increase the heat dissipation area, the outer surfaces of the fins 2 overlapped with the end portions 1-3 of the substrate 1 are wave-shaped curved surfaces, and compared with the traditional smooth surface structure, the heat dissipation effect of the wave-shaped curved surfaces is better. As shown in fig. 5, the fin 2 of the present embodiment is laid on the middle of the substrate 1. And heating objects can be arranged at both ends of the substrate 1, so that the space is saved.

Regarding the height of the fins 2, there can be various choices according to the practical application environment, and the height of the fins 2 laid on both sides of the substrate 1 in the embodiment is preferably the same or different, as shown in fig. 6, the height ratio of the fins 2 on both sides of the substrate 1 is 2: 1, the fins 2 on both sides have the difference in height, can save certain occupation space, do benefit to and install in narrow space, under the prerequisite that satisfies the heat dissipation, also can save some materials, reduced manufacturing cost.
