Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a radiating fin structure having a flow path type, and particularly to a radiating fin structure capable of obtaining a particularly preferable radiation efficiency and exhibiting a larger radiation ability.

[0002]

[Prior art]

 Nowadays, the computer industry is rapidly developing, and the heat generation of electronic heating elements such as microprocessor chips is getting higher and smaller, and the size is getting smaller. In order to allow the electronic heating element to work in an environment at an allowed temperature, heat radiation fins, which usually have a large area, are attached to the surface of the electronic heating element to cooperate with heat dissipation and to operate the electronic heating element. The service life can be controlled.

At present, there are three types of radiating fins that are often used, such as an aluminum stuffing type, a die-casting type, and a folding type. Manufacturing of aluminum-type and die-casting radiating fins has a limitation in machining capacity. (Total heat dissipation area per unit area) is limited, so when used for electronic heating elements that generate more and more heat, their volume and weight will increase further, and the heat dissipation of the folding type will increase. Due to the high density of the fins, there is an increasing tendency to replace aluminum stuffed and die cast fins.

As shown in FIG. 1, a conventional folding radiating fin 10a is formed by pressing a plurality of metal pieces 11a to have predetermined dimensions by a mechanical pressing method, and the metal pieces 11a are made of copper. Alternatively, the metal piece 11a is made of aluminum, has a U-shape, an L-shape, an I-shape, or the like, has a main body 12a, and has parallel bent sides 13a that are parallel to upper and lower sides of the main body 12a. The lower side 12a of the main body 12a is joined to the heat dissipation base 20a by a method such as adhesion or welding using the bent side portion 13a. The heat radiating base 20a is also made of a material such as copper or aluminum, which is advantageous in attaching the heat radiating base 20a to the surface of the electronic heating element, and provides cooperation for heat radiation.

However, the conventional radiation fin 10a simply forms a gap in the width direction between the metal pieces 11a, 11a, and the airflow simply flows in the lateral direction between the metal pieces 11a, 11a. The airflow cannot flow in the vertical direction between the metal pieces 11a, 11a, so that it is difficult for the heat radiation fin 10a to obtain a preferable heat radiation efficiency, and the larger heat radiation ability cannot be exhibited.

In addition, after the metal pieces 11a of the conventional radiating fin 10a are combined with each other, the bottom side of the radiating fin 10a becomes flat, and differs depending on the shape of the radiating base and the surface of the electronic heating element. It is difficult to carry out the change, so that they cannot be attached to the heat dissipation base and the electronic heat dissipation element of different shapes, which limits the use.

In the conventional radiating fin 10a, the metal piece 11a needs to be joined to the radiating base 20a by a method such as gel or welding, so that it takes time and trouble to assemble, which leads to an increase in production cost. May be like this.

Therefore, as can be seen from the above, the conventional radiating fin structure has obvious inconvenience and disadvantages in actual use and needs to be improved.

[0009] Therefore, the inventor of the present invention considers that the above-mentioned conventional problem can be solved, and proceeds with research and development, and at the same time, finally makes a design that is rational in accordance with academic operation and can solve the above-mentioned problem effectively. Devised.

[0010]

[Problems to be solved by the invention]

 According to the present invention, when forming the connecting mechanism of the radiating fin, a through hole corresponding to the main body of the radiating fin is formed, a gap in the width direction is formed between the metal pieces, and an air flow is generated between the metal pieces. Direction, and the air flow can be made to flow in the vertical direction in the flow path formed between the through holes of the metal pieces. It is a main object of the present invention to provide a flow path radiating fin structure characterized by being able to exhibit the above.

In the present invention, the length of the engaging hole in the vertical direction is slightly larger than the size of the engaging body, so that the length of the radiating fin in the vertical direction can be expanded and contracted and the flexibility can be improved. By forming the bottom surface of the radiating fin into a shape such as an arc surface or a curved surface, it is possible to perform different changes according to the surface shape of the radiating base and the surface of the electronic heating element. The next object is to provide a flow path type radiating fin structure characterized in that it can be attached to the radiating base and the electronic heating element and has flexibility in use.
