Abstract

The invention discloses a radiating fin. The radiating fin includes a radiating fin body and a glue nail; two first radiating groups and a plurality of second radiating groups are arranged on the radiating fin body; the plurality of second radiating groups are located between the two first radiating groups; each first radiating group consists of a plurality of first radiating fins separated from one another; each second radiating group consists of a plurality of second radiating fins separated from one another; and the radiating fin body is also provided with a through hole matched with the glue nail. According to the radiating fin provided by the invention, heat is radiated to the air through the two first radiating groups and the plurality of second radiating groups, thereby achieving the purpose of heat radiation of a heating element, and the radiating fin is simple in structure and strong in practicability.

Description

Fin

Technical field

The invention belongs to fin field, specifically fin.

Background technology

Fin is a kind of to the device of the easy heat-generating electronic elements heat radiation in electrical equipment, and power consumption increases thereupon, and therefore various electronic component also creates very huge heat, brings heat dissipation problem, creates heat abstractor thereupon.

Summary of the invention

The technical problem to be solved in the present invention is to provide fin and can dispels the heat to electronic component.

Technical scheme of the present invention is as follows: fin, comprises heat sink body and glue nail; Described heat sink body is provided with two the first heat radiation groups and multiple second heat radiation group; Multiple described second heat radiation group is all between two described first heat radiation groups; Described first heat radiation group is made up of multiple first radiating fin separated from one another; Described second heat radiation group is made up of multiple second radiating fin separated from one another; Described heat sink body is also provided with follows closely with described glue the perforation coordinated.

Fin provided by the invention, by described two the first heat radiation groups and multiple second heat radiation group in the middle of heat spreader to air, multiple described second heat radiation group all can realize heat radiation in various degree between two described first heat radiation groups, the heat radiation of described first heat radiation group is realized by the first radiating fin separated from one another, the heat radiation of described second heat radiation group is realized by the second radiating fin separated from one another, play the object realized heater element heat radiation, structure is simple, practical.

Further, the face of described heat sink body described first heat radiation group and the second heat radiation group is dorsad provided with the foam that a trap is closed.

Further, described fin also comprises conducting strip; Described conducting strip one end is connected by binder with the described heat sink body face of described first heat radiation group and the second heat radiation group dorsad, and joint face is positioned at closed described foamed cotton ring.

Further, the described first radiating fin length on first direction is greater than the length on described second radiating fin first direction.

Further, the upper surface that described first radiating fin and described second radiating fin contact with air is equipped with multiple groove.

Further, two described first heat radiation groups and multiple described second heat radiation group are arranged in matrix.

Further, between adjacent described between two the first radiating fin, there is arcuate furrow.

Further, two described first heat radiation groups are positioned at outside described heat sink body.

Further, the number of holes that described glue is followed closely and is mated is 2.

By illustrating, 1-heat sink body, 2-glue is followed closely, the 3-the first heat radiation group, the 4-the second heat radiation group, the 5-the first radiating fin, the 6-the second radiating fin, 7-foam, 8-conducting strip, 9-groove, 10-arcuate furrow.

Embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

It should be noted that first direction that the present invention mentions refers to X1 direction as shown in Figure 1, X1 direction is parallel with a wherein side of described heat sink body 1.

As shown in Figure 1, fin provided by the invention, comprises heat sink body 1 and glue nail 2; Described heat sink body 1 is provided with two the first heat radiation groups 3 and multiple second heat radiation group 4; Multiple described second heat radiation group 4 is all between two described first heat radiation groups 3; Described first heat radiation group 3 is made up of multiple first radiating fin 5 separated from one another; Described second heat radiation group 4 is made up of multiple second radiating fin 6 separated from one another; Described heat sink body 1 is also provided with follows closely 2 perforation coordinated with described glue.

As shown in Figure 2, as specific embodiment, the face of described heat sink body 1 described first heat radiation group 3 and the second heat radiation group 4 is dorsad provided with the foam 7 that a trap is closed, and described foam 7 can be used for insulation, heat radiation, fire prevention.

As shown in Figure 2, as specific embodiment, in order to make heat-generating electronic elements can high efficiency thermal energy transfer give described heat sink body 1, described fin also comprises conducting strip 8, then described conducting strip 8 just can give described heat sink body 1 thermal energy transfer, described conducting strip 8 can be connected by binder with the connection of described heat sink body 1, and joint face is positioned at closed described foam 7 encloses and avoid overlappingly with described foam 7 causing bad effect.

As shown in Figure 1, as specific embodiment, because described first radiating fin keeps to the side, the length that described first radiating fin 5 length on first direction is greater than on described second radiating fin 6 first direction contributes to extending the described fan backing life-span.

As shown in Figure 3, as specific embodiment, the upper surface that described first radiating fin 5 contacts with air with described second radiating fin 6 is equipped with multiple groove 9, effectively increases described fin heat exchange area, contributes to heat radiation.

As shown in Figure 1, as specific embodiment, two described first heat radiation groups 3 and multiple described second heat radiation group 4 are arranged in matrix, ensure that fin can play good radiating effect equally under the limited condition of setting height(from bottom).

As shown in Figure 4, as specific embodiment, there is between adjacent described between two the first radiating fin 5 arcuate furrow 10 and contribute to heat radiation, because two described first heat radiation groups 3 and multiple described second heat radiation group 4 are arranged in matrix, so also there is arcuate furrow 10 contribute to heat radiation between adjacent described between two the second radiating fin 6.

As shown in Figure 1, as specific embodiment, two described first heat radiation groups 3 are positioned at outside described heat sink body 1.

As shown in Figure 1, as specific embodiment, in order to better fix described fin, described glue nail 2 and the number of holes be mated are 2.
