[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a radiating fin concealed assembly structure, and more particularly to a folding radiating fin assembled so as to be hidden inside by a locking hole and a locking piece.

[0002]

[Prior art]

 With the rapid development of the computer industry, the heat generation of electric heating elements such as microprocessor chips has become higher and smaller, and the size of these elements has become smaller. In order to radiate to the environment outside the system and operate the electric heating element at the permitted temperature, a large area heat dissipation fin is generally attached to the upper surface of the electric heating element to cooperate with heat dissipation and effectively cooperate. The operation and service life of the electric heating element can be grasped.

At present, there are three types of heat radiation fins that are often used: an aluminum extrusion type, a die casting type, and a folding type. The production of aluminum extrusion type and die-cast type radiating fins has a limited radiating area due to the limitation of machining capacity. Therefore, when used for electric heating elements that generate more and more heat, their volume and weight Increasingly, according to those factors, the demand for light, thin, short and small demands of modern computer products is becoming increasingly unsatisfactory. In addition, there is a trend to increasingly replace aluminum extrusion die-type and die-cast type heat radiation fins because the folding type heat radiation fins can provide a larger heat radiation area.

FIGS. 1 and 2 show a structure of a conventional folding type heat radiation fin 10a. The heat radiation fin 10a is formed by processing a plurality of metal pieces 11a into a product having a predetermined size by a mechanical press working method. The metal piece 11a is formed of a material such as copper or aluminum. The metal piece 11a has a "U" shape, has a main body 12a and two bent sides 13a, and has two bent sides 13a. Are formed on the upper and lower sides of the main body 12a in a parallel state, and the two bent sides 13a are orthogonal to the main body 12a. Further, the two bent sides 13a have an assembly structure 14a, and the metal pieces 11a are connected and deposited by the assembly structure 14a to form the radiation fin means 10a having a predetermined volume.

The assembling structure 14a includes a plurality of locking holes 15a and locking pieces 16a corresponding to the locking holes 15a. The locking holes 15a are formed in the bent sides 13a, and the locking pieces 16a are bent in the bent sides. The metal fins 11a are formed so as to extend from the front portion of the fin 13a, and the metal pieces 11a are continuously locked and connected by the mutual locking of the locking holes 15a and the locking pieces 16a, so that the radiation fin means 10a can be formed. The heat dissipating fin means 10a is connected to a heat dissipating base (not shown) by a method such as adhesion or welding, and adheres the heat dissipating base to the electric heating element to cooperate with heat dissipating.

However, in the conventional radiating fin assembling structure, the assembling structure 14a including the locking holes 15a and the locking pieces 16a is exposed to the outside when the assembly is completed, so that the appearance is deteriorated and the assembling structure 14a is easy. The fins often become loose under the influence of external forces, and the combined structure of the heat-dissipating fins often collapses.

Therefore, as can be seen from the above, the conventional heat dissipating fin assembly structure clearly has its inconvenience and disadvantages in actual use and needs to be improved.

The inventor of the present invention feels that the above-mentioned problem can be solved, advances research and development, and can finally solve the problem effectively by designing the system in accordance with academic operation. This led to the proposal of the present invention.
