Abstract

The utility model relates to a radiation fin, a plurality of radiation fins are stacked each other to form a radiator, the radiation fin is provided with a body, the body is provided with a first bent part and a second bent part, the portion of the bent part connected with the adjacent radiation fin is provided with at least a lock part and a lock hole. The radiation fin has simple processing, convenient combination and flat arrangement, radiation surface area increment; therefore the utility model can reach good radiation effect.

Description

Radiating fin

Technical field

The utility model relates generally to heat abstractor, especially about a kind of radiating fin that is used for electronic product.

Background technology

Along with the continuous development of science and technology, people are more and more harsher for the volume requirement of PC especially notebook computer, we can say, volume, weight issue become computer the matter of utmost importance that will urgently solve.But, the influence that this development trend brings following two aspects for the heat dissipation problem of computer:

(1) because the interior space of computer housing is limited, and its inner parts are arranged more tight, is unfavorable for heat radiation;

(2) in addition, crowded inner space requires the weight of heat abstractor to want light, and volume is little, and requires to have better heat radiating effect.

But its heat radiation fin structure of existing radiator is too complicated, and the distance between the fin is excessive, and this just causes area of dissipation little, and radiating effect is not good, and radiating fin processing technology complexity, and manufacturing cost improves, and combination is inconvenient between the fin.

Summary of the invention

At existing defective of above-described existing radiating fin and demand, the utility model provides a kind of radiating fin of processing simple, combined and instant and good heat dissipation effect.

For realizing above goal of the invention, the utility model is taked following technical scheme:

This radiating fin has a main body, described main body offers one first kink and one second kink, the part that these kinks link to each other with adjacent radiating fin, be provided with an at least one buckling parts and a fastening hole, wherein, buckling parts is opened in these kinks and one of is not connected end with main body, and fastening hole is opened in these kink bending places, and this buckling parts fastening hole has the structure of snapping mutually: have a recess at this fastening hole by main body one side, this recess both sides all offers a retaining rib; Buckling parts comprises first and the second portion that is in the connection of " T " font.

Therefore, a plurality of above-mentioned these radiating fins are stacked, and make the mutual snapping of fastening hole of its buckling parts and adjacent fin, can form radiator; By the radiating fin of the utility model, it is simple in structure, and processing technology is also simple, and mutually combined and instant and arrange smoothly increases cooling surface area, therefore, can reach good radiating effect.

Description of drawings

Below with reference to the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the stereogram of the utility model radiating fin.

Figure 1A is an A place partial enlarged drawing among Fig. 1.

Fig. 2 is the mutual combination stereogram of the utility model several dissipation fins.

Fig. 2 A is a B place partial enlarged drawing among Fig. 2.

Embodiment

See also Fig. 1, shown in the 1A, represented the utility model radiating fin three-dimensional structure diagram, this radiating fin is made by the good material of thermal conductivity, as copper, aluminium etc., it has a main body 10, offer one first kink 11 and one second kink 12 on described this main body 10, this is first years old, two

kinks

11,12 with main body 10 bending at an angle, and this is first years old, two

kinks

11,12 parts that link to each other with adjacent radiating fin, be equipped with at least one buckling parts 13 and at least one fastening hole 14, wherein, buckling parts 13 is opened in these

kinks

11,12 one of are not connected end with main body 10, fastening hole 14 be opened in this first,

second kink

11,12 bending places, and this buckling parts 13, fastening hole 14 has the structure of snapping mutually: have a recess 141 at this fastening hole 14 by main body 10 1 sides, these recess 141 both sides all offer a retaining rib 142; First 131 and second portion 132 that buckling parts 13 includes " T " font to connect.

See also Fig. 2, shown in the 2A, for stacking the combination back mutually, several dissipation fins constitutes radiator, during combination, with first of its bending certain angle,

second kink

11,12 pressings, make first,

second kink

11,12 roughly become 90 ° with main body 10, make the fastening hole 14 mutual snappings of its buckling parts 13 and adjacent radiating fin, make the first 131 of buckling parts 13 place in the recess 141 of adjacent radiating fin fastening hole 14,132 of second portions are fastened in the fastening hole 14, and in the space between the order retaining rib 142 embedding buckling partss 13 and first kink 11, so, can realize the mutual snapping of two radiating fins.

According to the above, a plurality of above-mentioned these radiating fins are stacked, and make the mutual snapping of fastening hole of its buckling parts and adjacent fin, can form radiator; By the radiating fin of the utility model, it is simple in structure, and processing technology is also simple, and mutually combined and instant and arrange smoothly increases cooling surface area, therefore, can reach good radiating effect.

The above-mentioned the drawings and the specific embodiments that disclose only are a preferred embodiment of the present utility model, are not for limiting practical range of the present utility model; Those skilled in the art are in the technical characterictic scheme of setting forth according to the utility model, and other equivalence of being done changes or modifies, and all should be encompassed in the claim scope of the utility model.
