Abstract

The utility model discloses a radiating fin. A radiator is formed after the radiating fin is combined with a cavity and a support; one end of the radiating fin is provided with an inner wall; the outer surface of the inner wall is in contact with the cavity; the other end of the radiating fin is also connected with at least one groove; the groove is matched with the support; the side edges of one end of the radiating fin, which are near the inner wall, are also respectively provided with a buckling part; the buckling parts comprise bayonets and fasteners; and the fasteners on one radiating fin are respectively matched with the bayonets on another radiating fin. The radiator formed by the radiating fin has simple processing, light weight and flexible design.

Description

Radiating fin

[technical field]

The utility model relates to a kind of radiating fin, the particularly a kind of radiating fin that can assemble arbitrarily as required.

[background technology]

The CPU on general or traditional desktop PC and the server or the main material of North Bridge radiating module are at present: aluminium or copper material, and material is more single, can not require to accomplish optimized design in response to weight, cost and the heat radiation of product.Existing radiating fin is as follows:

With reference to Fig. 1, shown in Figure 2, it is the overall schematic and the decomposing schematic representation of existing radiating fin.Existing radiating fin comprises:

Radiating fin 11, position is provided with an opening 111 in the middle of it, and in some embodiment, this radiating fin 11 is selected the fine aluminium material for use;

Heat-conducting part 12, it places above-mentioned opening 111 fully and cooperates contact, and this heat-conducting part 12 is selected the fine copper material for use.

In other embodiment, some existing radiating fins adopt the mode of aluminium material extrusion molding to obtain, and some radiating fin needs to be made up of radiating fin and cooling base two parts.

There is following defective in existing radiating fin:

1, design is dumb, needs to be made up of radiating fin and two ones of cooling bases;

2, material is selected for use dumbly, and weight is big, the cost height.

[summary of the invention]

In view of this, the purpose of this utility model is to provide a kind of radiating fin, with realize that processing is simple, the advantage of combined and instant, in light weight, flexible design.

For achieving the above object, the utility model provides a kind of radiating fin, constitutes a heating radiator after itself and cavity and the holder combination, and an end of this radiating fin is provided with an inwall, and the outside surface of this inwall contacts with above-mentioned cavity; This radiating fin other end also is provided with at least one groove, and this groove matches with support; And this radiating fin is near also being respectively equipped with a buckling parts on the side of inwall one end, and this buckling parts comprises: a bayonet socket and a buckle, and the buckle on radiating fin all matches with bayonet socket on another radiating fin.

Especially, the difference of above-mentioned radiating fin number assembling back constitutes the heating radiator of different sizes.

Compared to prior art, radiating fin of the present utility model has following advantage:

1, flexible design;

2, processing is simple, and assembling fastens and gets final product behind the continuous stamp of punch press;

3, combined and instant only needs first and last end with each radiating fin fasten and gets final product.

For the purpose of this utility model, structural attitude and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:

[embodiment]

To shown in Figure 6, it is respectively the structural representation of radiating fin of the present utility model with reference to Fig. 3, two radiating fins in conjunction with after structural representation, one-piece construction synoptic diagram after the radiating fin combination and the structural representation in preferred embodiment.

Radiating fin of the present utility model, itself and cavity 3 and support 4 combination backs constitute heating radiators, and an end of this radiating fin is provided with an inwall 21, and the outside surface of this inwall 21 contacts with above-mentioned cavity 3; This radiating fin other end also is provided with at least one groove 22 (in present embodiment, the quantity of groove 22 is two), and this groove 22 matches with support 4, and the two back of matching makes that the radiating fin after the combination is more firm; And this radiating fin also is respectively equipped with a buckling parts 23 near on the side of inwall one end, this buckling parts 23 comprises: a bayonet socket 231 and a buckle 232, and the buckle 232 on radiating fin all with another radiating fin on bayonet socket 231 match cooperating and cavity 3 between a plurality of radiating fins of merga pass, support 4 constitutes a heating radiator (with reference to Fig. 6), and the size of heating radiator decides according to the number of above-mentioned radiating fin, selected according to actual needs, in present embodiment, a plurality of radiating fins fastening rear chambers 3 place the circular hole of being made up of inwall 21 (figure does not indicate) and are in contact with one another, and then the heat of conduction cavity 3.The heatsink weight of existing structure is big, the cost height, and general heatsink weight is 200g-300g, and the weight of the heating radiator of being made up of radiating fin of the present utility model is about 50g, and processing is simple, combined and instant, flexible design.

Claims

1. constitute a heating radiator behind radiating fin, itself and cavity and holder combination, it is characterized in that: an end of this radiating fin is provided with an inwall, and the outside surface of this inwall contacts with above-mentioned cavity; This radiating fin other end also is provided with at least one groove, and this groove matches with support; And this radiating fin is near also being respectively equipped with a buckling parts on the side of inwall one end, and this buckling parts comprises: a bayonet socket and a buckle, and the buckle on radiating fin all matches with bayonet socket on another radiating fin.

2. radiating fin as claimed in claim 1 is characterized in that, the difference assembling back of above-mentioned radiating fin number constitutes the heating radiator of different sizes.
