Benefits of technology
The present invention provides a heat sink structure and its manufacturing method that connect the main body and radiating fins using high-speed impact. Additionally, the invention includes a non-planar surface on the main body connection section for better connection friction. The heat sink structure also has improved heat dissipation efficiency.
Problems solved by technology
As a result, the number of the mounted radiating fins is reduced.2. The manufacturing method includes numerous steps so that the manufacturing time is quite long.

Embodiment Construction
[0065]Please refer to FIGS. 1 and 2. FIG. 1 is a perspective exploded view of the present invention. FIG. 2 is a perspective assembled view of the present invention. The heat sink 10 of the present invention includes a main body 12 and multiple first radiating fins 13 connected to an outer circumference of the main body 12. The main body has a first end 121 and a second end 122.
[0066]As shown in FIG. 1, the first and second ends 121, 122 of the main body 12 define a longitudinal direction a. Referring to FIG. 4B, multiple main body connection sections 123 are formed on the surface of the main body and extend from the first end 121 to the second end 122 in the longitudinal direction a. (The main body connection sections 123 are distributed over the outer circumference of the main body equivalently or inequivalently). The main body 12 is formed with multiple thrust sections 124 near the first end 121 in communication with the main body connection sections 123 (as shown in FIG. 4B). Th...

Abstract
A heat sink structure and a manufacturing method thereof. The heat sink includes a main body having multiple main body connection sections and multiple radiating fins each having a connection section. The main body has a first end and a second end. The first and second ends define a longitudinal direction. The multiple radiating fins are placed in a mold. A mechanical processing measure is used to high-speed impact the main body so as to thrust the main body into the mold. Accordingly, the connection sections of the radiating fins placed in the mold are high-speed thrust into the main body connection sections and moved in the longitudinal direction to the second end of the main body to tightly integrally connect with the main body.
Description
[0001]This application claims the priority benefit of Taiwan patent application number 101127729 filed on Aug. 1, 2012.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates generally to a heat sink structure and a manufacturing method thereof, and more particularly to an annular heat sink structure and a manufacturing method thereof.[0004]2. Description of the Related Art[0005]The conventional cylindrical heat sink includes a cylindrical body and multiple radiating fins connected to the circumference of the cylindrical body. There are several conventional measures for connecting the radiating fins to the circumference of the cylindrical body. For example, a prior art discloses a cylindrical heat sink and a method of tightly planting radiating fins of the heat sink and an application device thereof. According to the method, a mold seat drivable by a power source to create stepped rotational operation is provided. A cylindrical body is located o...
