The radiator structure has flexible structure design and low cost, can give attention to the heat-radiating performance and product weight, and is easy to assemble without special processing equipment.

Description

Heat spreader structures

[technical field]

The present invention relates to a kind of heat spreader structures, particularly a kind of quick, light weight and low heat spreader structures of cost assembled.

[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 heat spreader structures is as follows:

With reference to Fig. 1, shown in Figure 2, it is the overall schematic and the decomposing schematic representation of existing heat spreader structures.Existing heat spreader structures 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 heating radiators adopt the mode of aluminium material extrusion molding to obtain, and some heat spreader structures needs to be made up of radiating fin and cooling base two parts.

There is following defective in existing heat spreader structures:

1, heat dispersion is low;

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

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

[summary of the invention]

In view of this, the object of the present invention is to provide a kind of heat spreader structures, with realize that processing is simple, combined and instant, in light weight, advantage that cost is low.

For achieving the above object, the invention provides a kind of heat spreader structures, this heat spreader structures comprises:

Radiating fin, position is provided with an opening in the middle of it;

First radiating part, it is located in the above-mentioned opening and cooperates contact, and this first radiating part is provided with a groove, and this first radiating part is selected copper material for use;

Second radiating part, it places in the above-mentioned groove fully and is in contact with one another this second radiating part aluminium material.

Compared to prior art, heat spreader structures of the present invention has following advantage:

1, flexible design, cost are low;

2, can take into account heat dispersion and product weight;

3, combined and instant, need not special process equipment.

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

Fig. 6 illustrates the heat radiation synoptic diagram of heat spreader structures of the present invention in preferred embodiment.

[embodiment]

With reference to Fig. 3, Fig. 4 and shown in Figure 5, it is respectively the overall schematic and the decomposing schematic representation of heat spreader structures of the present invention.

Heat spreader structures of the present invention, it comprises:

Radiating fin 21, position is provided with an opening 211 in the middle of it, in present embodiment, these radiating fin 21 rounded distributions, these radiating fin 21 flexible designs can be designed to difformity according to the actual needs in other embodiment, as: rectangular distribution;

First radiating part 22, it is located in the above-mentioned opening 211 and is in contact with one another fully, and this first radiating part 22 is provided with a groove 221, and the bottom of this groove 221 contacts with a pyrotoxin 20, thereby carries out heat conduction, and this first radiating part 22 is selected copper material for use;

Second radiating part 23, it places in the above-mentioned groove 221 fully and is in contact with one another these second radiating part, 23 aluminium materials.

By the mode combination of riveting, in other embodiment, the three also can adopt other combinations between wherein above-mentioned radiating fin 21, first radiating part 22 and second radiating part 23, and this case is not limited to the riveting mode.

In the lump with reference to shown in Figure 6, heat spreader structures of the present invention is in a preferable enforcement, itself and fan 30 fit applications are in a pyrotoxin 20 places, pyrotoxin 20 is by contacting with first radiating part 22, thereby with heat transferred first radiating part 22, (direction of arrow is the heat flow direction among the figure) and through first radiating part 22 by shedding.Heat spreader structures of the present invention is by adopting second radiating part 23 and aluminium material, makes the weight saving of entire radiator structure, and then cost descends, and combined and instant, need not special process equipment and only can finish by the mode of riveting.

Claims (2)

1. a heat spreader structures is characterized in that, this heat spreader structures comprises:

Radiating fin, position is provided with an opening in the middle of it;

First radiating part, it is located in the above-mentioned opening and cooperates contact, and this first radiating part is provided with a groove, and this first radiating part is selected copper material for use;

Second radiating part, it places in the above-mentioned groove fully and is in contact with one another this second radiating part aluminium material.
