[Prior art]

 With the rapid upgrade of the computer industry, the operating speed of electronic devices will become faster and faster, and the heat energy generated will increase accordingly. Therefore, in order to enable the electronic device to operate in an environment at an allowable temperature, a heat radiation piece having a large area is attached to the surface of the electronic device to improve the heat radiation efficiency.

[0003] However, heat-dissipating pieces made of aluminum or die-casting, which are currently widely used, are limited to machining and have a fixed shape, and are large for electronic elements that dissipate a large amount of heat. It has to be custom-made to have an area, and in such a case, the weight may increase. The foldable radiating pieces are thin and can be assembled by stacking to increase the radiating area. It is.

FIG. 1 shows the structure of a conventional foldable heat radiating piece 1a. The heat radiating piece 1a is formed by forming a plurality of plate pieces 10a having a similar size by continuous press working of a machine. In addition, bent side portions 11a are formed at both ends thereof, these two bent side portions 11a are parallel to each other, and the edges are formed in a U-shape. The bent side portion 11a is connected to the heat dissipation base 2a of the electronic element by attaching the heat sink, thereby achieving the effect of heat dissipation.

However, if the plate 10a is adhered to the heat radiating base 2a by the heat conductive gel, it is inconvenient for assembling, the processing time is long, and a large amount of the heat conductive gel is consumed, resulting in an increase in cost. However, they are no longer suitable for mass production and are not economical.

[0006]

[Problems to be solved by the invention]

 Therefore, the conventional foldable heat radiating piece has inconvenience and its disadvantages when used for actual production and assembly, and needs to be improved.

[0007] The present invention has been made in view of the above-mentioned drawbacks of the conventional product, and provides a configuration that is rational in design and can effectively improve the drawbacks.

[0008]

[Means for Solving the Problems]

 The main purpose of the present invention is to provide a heat dissipating piece assembling structure, and the heat dissipating piece is made up of a plurality of metal material plate pieces, and the plate piece has an engagement / disengagement component. The heat dissipation piece is formed by continuously locking the sheet pieces together, and it is not necessary to adhere each piece to the heat dissipation base, which simplifies assembly, thereby reducing the working time and heat transfer gel. It can save cost and is suitable for mass production. Further, since the heat radiation piece is formed by assembling a plurality of members, a plurality of air flow paths can be formed, and the plurality of air flow paths can be connected by forming through holes in those plate pieces. The heat radiation effect can be improved.

Hereinafter, preferred embodiments of the heat dissipating piece assembly structure of the present invention will be described in detail with reference to the accompanying drawings to explain the configuration, technical principle, and operation of the present invention in detail. The drawings and drawings are merely examples of the present invention, and do not limit the configuration of the present invention to those configurations.

[Embodiment of the invention]

 2 to 4 are an assembled perspective view, an exploded perspective view, and a cross-sectional view taken along the line AA of the present invention, respectively. The present invention provides a heat dissipating piece assembling structure, in which the heat dissipating piece 1 is assembled by continuously pressing a machine to form plate pieces 10 having a plurality of predetermined specifications. A bent side portion 11 is formed by bending an edge portion of the plate piece 10, the bent side portion 11 is formed to be inclined slightly outward, and the engagement / disengagement portion 12 The area of the bent side portion 11 is formed so that a part thereof can be connected to the plate piece 10, which is useful for air circulation, or is formed entirely at one end of the plate piece 10 to form the air flow path 15. And allow air to flow in from both sides.

The engagement / disengagement component 12 includes an engagement / disengagement concave portion 13 and an engagement / disengagement convex portion 14, and the engagement / disengagement concave portion 13 is press-formed on a bent side portion 11 of the plate piece 10. At the edge of the side 11, a corresponding engaging / disengaging convex portion 14 is formed, and if the engaging / disengaging concave portion 13 and the engaging / disengaging convex portion 14 are mutually engaged and disengaged, the plate piece 10 can be continuously assembled. Let When continuously assembled, the heat radiation piece 1 is formed.

The shape of the engagement / disengagement component 12 can be any shape such as a circle, a triangle, a square, or a polygon (see FIGS. 5 and 6), and the number thereof depends on the size of the plate 10. It can be increased or decreased appropriately. In addition, the heat radiation piece 1 forms a plurality of air flow paths 15 by being assembled, and these air flow paths 15 are isolated by the plate piece 10. The air passages can be connected to each other, and the heat radiation effect can be improved.

As shown in FIG. 7, the bent side portion 11 above the plate piece 10 is partially connected to form an open space, which is advantageous for air flowing into the flow path 15. Alternatively, as shown in FIG. 8, the bent sides 11 may be formed on both sides of the plate 10, but the area where the bent sides 11 below the plate 10 contact the heat radiation base 2 is increased. Therefore, in the general case, the entire bent side portion 11 at the bottom of the plate piece is used, and the number of bent side portions can be appropriately increased or decreased according to the number of disengagement components. .

As shown in FIGS. 9 and 10, the material of the edge portion of the plate 10 may be bent to form the bent side portion 11. In this case, the heat radiation area is slightly reduced, but the effect of saving materials can be achieved.

[0015] Since the heat dissipating piece assembling structure of the present invention is formed by assembling a plurality of plate pieces 10 by the engagement / disengagement portion 12, when compared with the conventional folding type heat dissipating piece, the assembly is performed. The heat radiation piece 1 is adhered to the heat radiation base 2 of the electronic element because the heat radiation piece 1 is attached to the electronic element heat sink because the heat radiation piece 1 can be reduced, the labor and time required for the operation can be reduced, and the amount of heat conduction gel can be reduced. In this case, the heat radiating area can be effectively increased, and the heat radiating effect is superior to that of the conventional aluminum stuffed and molded products.

[0016]

[Effect of the invention]

 As described above, the present invention has the disadvantage that the conventional foldable heat dissipating piece is formed by adhering the plate pieces to each other with the heat conducting gel, but the assembling work is inconvenient and the material (heat conducting gel) is wasted. It improves the disadvantages, the disadvantages with many processing steps, and the disadvantages that are not economical.
