The present invention relates to a fastening structure of a heat sink.

Generally, heat sinks are used for heat dissipation of power components.

1 is a cross-sectional view showing a fastening structure of a conventional heat sink.

As shown in FIG. 1A, which is a front view of a conventional heat generating part fastened to a heat sink, the heat generating part 30 is fastened and fixed to the heat sink 10 by a screw 20.

FIG. 1B is a bottom view of the heat generating part 30 fastened to the heat sink 10, and FIG. 1C is an enlarged view of part A of FIG.

However, the fastening method using the screw 20 as described above has the following problems.

As shown in (b) of FIG. 1, the screw 20 is rotated using an electric driver (not shown) to couple and fix the heat generating part 30 to the heat sink 10. Due to the rotational torque, the screw 20 presses the heat generating part 30 too strongly so that the heat generating part 30 is damaged and a quality defect occurs.

In addition, as shown in FIG. 1C, the peripheral portion 22, which is a portion in which the screw 20 is in close contact with the portion of the heat generating part 30, has a close contact force between the heat generating part 30 and the heat sink 10. However, the separation portion 32, which is a portion where the screw 20 is not in direct contact with each other, has a relatively low adhesion force between the heat generating part 30 and the heat sink 10, so that the adhesion force decreases as the distance from the screw 20 increases. There is a problem that the heat dissipation effect is lowered.

The present invention can be coupled to the heat sink itself heat generating parts with high adhesion.

The present invention provides a fastening structure of a heat sink including a heat sink and a heat sink integrally provided with a coupling part to which the heat generating part is fastened.

In addition, the heat sink of the present invention includes a vertical portion and a horizontal portion extending from the end of the vertical portion, the coupling portion for fastening the heating component is provided integrally.

The coupling portion may include a vertical portion and a horizontal portion extending from the end of the vertical portion, and a convex portion may be formed at the end of the horizontal portion in the heat sink direction.

In addition, the convex portion may be in the shape of a convex curved portion or a convex protrusion, a locking jaw may be provided in the heat sink, and the coupling portion and the locking jaw may be provided in plural.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

Figure 2 is a cross-sectional view showing a fastening structure of the heat sink of the present invention, Figure 3 is a cross-sectional view of the heat generating component coupled to the heat sink of FIG.

The fastening structure of the heat sink according to the present invention includes a heat sink 100 in which a heat generating part 300 and a coupling part 200 to which the heat generating part 300 is fastened are integrally provided.

The coupling part 200 is simultaneously molded when the heat sink 100 made of aluminum is extruded using an extrusion die (not shown).

The coupling part 200 includes a vertical part 210 and a horizontal part 215 extending from the end of the vertical part 210, and the heat sink 100 direction is formed at the end of the horizontal part 215. Convex portions 220 and 225 are formed.

FIG. 2C is an enlarged view of a portion B of FIG. 2A, and FIG. 2D is a variation of FIG. 2C.

In addition, as shown in (c) and (d) of FIG. 2, the convex portions 220 and 225 may have the shape of the convex curved portion 220 or the convex protrusion 225, and the convex curved portion 220 is horizontal. It is formed to be bent in the direction of the heat sink 100 at the end of the portion 215, and refers to the overall shape is curved, and may be partially folded at an angle.

The convex protrusion 225 has a rounded end portion in a shape that is vertically bent in the direction of the heat sink 100 at the end of the horizontal portion 215.

On the other hand, the heat sink 100 is provided with a locking jaw 110 at a position adjacent to the coupling portion 200, the heating element 300 is inserted into the coupling portion 200 and in close contact with the heat sink 100. The locking jaw 110 is caught and can not be easily pulled out.

When a plurality of heat generating parts 300 are coupled to the heat sink 100, the coupling part 200 and the locking jaw 110 are provided in plural.

Referring to the operation of the present invention having the structure as described above are as follows.

The coupling part 200 serves to fasten the heat generating part 300 to be in close contact with the heat sink 100.

More specifically, as shown in FIG. 3A, the coupling part 200 including the vertical part 210, the horizontal part 215, and the convex bent part 220 is formed in a hook shape to generate a heating part 300. ) Can be subjected to a constant tension in the state coupled to the heat sink (100).

In addition, the convex portions 220 and 225 have a convex curved portion 220 or a convex protrusion 225 so that the heat generating part 300 can be easily introduced into the enclosed space between the coupling portion 200 and the heat sink 100. It is a shape to say.

In addition, the catching jaw 110 serves to prevent the heat generating component 300 from coming off by an external impact in a state in which the coupling part 200 is fastened to the coupling part 200.

As shown in (b) of FIG. 3, the coupling part 200 uniformly presses the heat generating parts 300 so that the heat sink 100 and the heat generating parts 300 are closely contacted with each other.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

As described above, according to the present invention, since the screw is not used, component damage due to torque can be prevented and the cost can be reduced.

In addition, the heat dissipation performance is improved by increasing the contact area between the heat generating parts and the heat sink.

The vertical part serves to allow the heating element to receive a constant tension while being coupled to the heat sink.

The convex portion has a convex curved portion or a convex protrusion to allow the heating component to be easily introduced into a space surrounded by the coupling portion and the heat sink.
