Abstract
The utility model relates to the technical field of manufacturing of radiators, in particular to a cooling fin. The cooling fin comprises a cooling fin body. Upper heat dissipation holes and lower heat dissipation holes are formed in the two faces of the cooling fin body respectively, and arc-shaped flow guide plates are arranged on the upper heat dissipation holes and the lower heat dissipation holes. Anchor change stretching holes are formed between the upper heat dissipation holes and the lower heat dissipation holes, bosses are arranged around the anchor change stretching holes, and the height of the bosses and the height of the flow guide plates are the same in height. The cooling fin is simple in structure, the upper heat dissipation holes and the lower heat dissipation holes are formed in an existing cooling fin, the flow guide plates are installed on the upper heat dissipation holes and the lower heat dissipation holes, the upper heat dissipation holes, the lower heat dissipation holes and the flow guide plates are all formed by one-time stamping through a stamping grinding tool, and therefore the heat dissipation effect of the cooling fin is greatly improved. The anchor change stretching holes with the certain height are directly stamped outside original round holes connected with metal pipes, connecting tightness of the round holes and the metal pipes is increased and an existing limiting ring is replaced at the same time, and due to one-time stamping forming, production efficiency is greatly improved.
Description
Technical field
The utility model relates to the manufacturing technology field of radiator, relates in particular to a kind of fin.
Background technology
In radiator production, metal tube and suit fin thereon closely need to be combined, can guarantee good heat transfer and heat conduction, and weight be light, service life is longer.At present, the on-link mode (OLM) of metal tube and fin is all that the mode that interference is connected connects, on fin, first stamp out some connecting holes, retelling metal tube penetrates, between every fin, there is certain thickness spacing ring with one and control the distance between two adjacent fin, to reach better radiating effect.The connected mode of above fin and metal tube need to be controlled with a spacing ring distance of adjacent two fin, multiple fin are superimposed and are combined into radiator, and this kind of fin radiating effect is poor and increase because needs mounting limit ring causes cost of manufacture.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of fin is provided, and improves radiating efficiency, reduces the production cost of enterprise.
The utility model for achieving the above object, by the following technical solutions:
A kind of fin, is characterized in that: comprise heat sink body; The two sides of described heat sink body is respectively equipped with louvre and lower louvre, and described upper louvre and lower louvre top are provided with the deflector of arc; Between described upper louvre and lower louvre, be provided with and become anchor stretchable holes, described change anchor stretchable holes is provided with boss around, and the height of described boss is identical with the height of described deflector.
Described change anchor stretchable holes is between adjacent upper and lower louvre.
Deflector on described lower louvre towards direction and described upper louvre on deflector towards opposite direction.
Described upper louvre, lower louvre and deflector are bar shaped.
The beneficial effects of the utility model are: the utility model is simple in structure, by offer upper and lower louvre on existing fin, and mounting guiding board on upper and lower louvre, upper and lower louvre and deflector are all one time punching molded with punching press grinding tool, have greatly increased the radiating effect of fin; Original circular hole being connected with metal tube is directly stamped out to the change anchor stretchable holes with certain altitude outward, substituted existing spacing ring having increased in being connected compactness with metal tube, owing to being disposable punch forming, greatly improved production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
In figure: 1, heat sink body; 2, upper louvre; 3, lower louvre; 4, deflector; 5, become anchor stretchable holes; 6, boss.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of fin, comprises heat sink body 1; The two sides of described heat sink body is respectively equipped with louvre 2 and lower louvre 3, upper louvre and lower louvre lay respectively at the both sides of heat sink body, described upper louvre and lower louvre top are provided with the deflector 4 of arc, deflector on described lower louvre towards direction and described upper louvre on deflector towards opposite direction, come like this can enter into fin to the wind of different directions, increase radiating effect.Between described upper louvre and lower louvre, be provided with and become anchor stretchable holes 5, described change anchor stretchable holes is provided with boss 6 around, the height of described boss is identical with the height of described deflector, and this boss has substituted the spacing ring in original technology, directly can in punch press, utilize special mould to go out.In order reasonably to utilize the space of heat sink body, described change anchor stretchable holes is between adjacent upper and lower louvre.In order to increase the radiating effect of frame deflector, described upper louvre, lower louvre and deflector are bar shaped.
The utility model is simple in structure, by offer upper and lower louvre on existing fin, and mounting guiding board on upper and lower louvre, upper and lower louvre and deflector are all one time punching molded with punching press grinding tool, have greatly increased the radiating effect of fin; Original circular hole being connected with metal tube is directly stamped out to the change anchor stretchable holes with certain altitude outward, substituted existing spacing ring having increased in being connected compactness with metal tube, owing to being disposable punch forming, greatly improved production efficiency.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (4)
1. a fin, is characterized in that: comprise heat sink body; The two sides of described heat sink body is respectively equipped with louvre and lower louvre, and described upper louvre and lower louvre top are provided with the deflector of arc; Between described upper louvre and lower louvre, be provided with and become anchor stretchable holes, described change anchor stretchable holes is provided with boss around, and the height of described boss is identical with the height of described deflector.
