[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a multi-layered heat-dissipating element structure, which is used particularly for heat dissipation of electronic heating elements such as microprocessors, has a high aspect ratio and high-density heat dissipation area, and can be applied to mass production and assembly. When it is attached to a heat dissipation base or a heat pipe, it relates to a multiple heat dissipation piece structure that can effectively increase the heat dissipation area and greatly improve the heat dissipation capacity.

[0002]

[Prior art]

 In recent years, the computer industry has rapidly developed, and the size of electronic heating elements, such as microprocessors, has been reduced while increasing the amount of heat generated. Conventionally, a large-area heat radiating device is arranged close to the electronic heating element to operate, thereby improving a heat radiating effect.

[0003] At present, the radiating pieces used are generally aluminum-packed products, die-cast products, and foldable products, and the production of aluminum-packed products and die-cast products is of high machining capability. Due to restrictions, its fineness (total heat dissipation area per unit volume) is limited. Therefore, when it is used for an electronic heating element that generates more and more heat, its volume and weight become even larger.

[0004] As can be seen from the foregoing, the conventional heat sink has inconveniences and drawbacks in actual use and needs to be improved.

[0005]

[Problems to be solved by the invention]

 According to the present invention, the flow path formed by stacking the heat radiating pieces is more than twice as fine as the heat radiating pieces of the conventional aluminum-packed molded article and the die-cast molded article, and the flow path is sealed or partially closed. It is a main object of the present invention to provide a multiple heat radiation piece structure that can be broken to allow a flow path to become a passage and is more tolerable than a conventional folding heat radiation piece.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has a structure in which a plurality of radiating pieces are manufactured by press working, and the radiating pieces have a structure in which the bent side portions at both ends of the radiating pieces are engaged with each other. The present invention provides a multi-piece heat radiation piece structure capable of forming a heat radiation piece structure having a required volume by engaging and connecting the heat radiation pieces.

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1 to FIG. 3, the present invention provides a multiple radiating piece structure, and the multiple radiating piece 10 of the present invention is formed by pressing a plurality of metal pieces 11 into a predetermined size by pressing. The metal pieces 11 are made of a material having excellent heat conductivity, such as aluminum or copper, and the metal pieces 11 are processed to have a U-shaped cross section, have a main body 12, and bend side portions 13 at both ends of the main body 12. Are formed, the two bent sides 13, 13 are parallel, and the bent sides 13, 13 at both ends have an engaging structure 14, have a close engaging function, and are obtained by pressing. Each metal piece 11 is engaged and connected by an engagement structure 14 to form a heat dissipation piece structure having a predetermined volume.

The engaging structure 14 has an engaging notch 15 and an engaging member 16, and the engaging notch 15 is formed on the bent side portions 13 at both ends of the metal piece 11 by pressing. An engaging member 16 is formed at the tip of the bent side portion 13, and the metal pieces 11 are connected continuously by engaging the engaging notch 15 and the engaging member 16 with each other to form a heat radiation piece. Form structure 10.

The engaging structure 14 is divided into two types, a forward engaging type and a reverse engaging type. In the case of the forward engaging type, the engaging member 16 is made of a metal piece. In the case of a type in which the bent side portion 13 is formed by pressing to protrude and engage in the opposite direction, the engaging member 16 is formed by pressing a metal piece and bending it in reverse. . The shape of the engaging member 16 is formed in any shape such as a square, a circle, a triangle, or a polygon (see FIGS. 4 and 5). The number can be appropriately increased or decreased according to the size of the heat radiation piece 10. Further, the multiple heat radiation pieces 10 are deposited to form the multiple flow paths 17. These flow paths 17 can be sealed, but the metal pieces 11 can be appropriately torn to pass through the flow paths 17.

[0010] The multiple radiator element structure 10 of the present invention can be used in the field of heat radiation of an electronic heating element such as a microprocessor, and this type of multiple radiator element 10 has a high aspect ratio and a high radiating area. It is useful for mass production and assembling, and when this heat radiation piece structure 10 is pasted to the heat radiation base (or heat conduction tube) 20 of the electronic heating element via the heat conduction gel, the heat radiation area can be effectively increased and the heat radiation ability is improved. it can.

The multi-piece heat radiation piece structure 10 of the present invention has twice or more the fineness of the conventional aluminum-packed molded article and the die-cast type heat radiation piece. Therefore, it can be completely sealed or partially torn so that it can be passed through, and is more tolerable than the conventional folding type heat radiating piece, and provides a preferable heat radiating piece structure.

The multiple radiating piece structure 10 of the present invention is continuously engaged by the engaging structure 14 to form the radiating piece structure 10 having a predetermined volume, and is attached to the radiating base 20 of the electronic heating element. In addition, it is not necessary to bond the metal pieces 11 to the heat radiation base 20 one by one, so that the time and the number of steps for assembling can be saved, and the cost can be greatly reduced.

[0013]

[Effect of the invention]

 As described above, the present invention is used in the case of an electronic heating element that has a finer limit due to the limitation of the machining limit of the heat radiation piece by the conventional aluminum stuffed product and the die cast product, and the heat generation amount is increasing more and more. In this case, the problem of increasing the volume and weight of the heat radiation piece is solved, and a heat radiation piece structure which is more tolerable to use than the conventional folding type heat radiation piece structure and is considerably superior is provided.
