The utility model discloses a kind of LED lamp heat sink, comprise one for installing the pedestal of light source, described pedestal is provided with multiple heat-conducting piece, each heat-conducting piece is provided with a fin, multiple fin interval forms a line, and multiple fin is provided with the changeless fixture of spacing between two fin keeping adjacent simultaneously.Because radiator of the present utility model is by forming a line multiple fin and adopting fixture by the spacing locking between adjacent two fin, thus make adjacent fin can not be close to each other or be close together, ensure that the spacing between abutting fins immobilizes, therefore heat can reject heat in external environment from fin better and go, and then makes radiator of the present utility model can have good heat dispersion.

Description

A kind of LED lamp heat sink

Technical field

The utility model relates to a kind of radiator, particularly a kind of LED lamp heat sink.

Background technology

As everyone knows, LED operationally can produce a large amount of heats, the heat produced when working to make LED can promptly distribute, general LED all can be equipped with radiator, present radiator generally adopts following structure: comprise one for installing the pedestal of LED light source, pedestal is connected with polylith fin by multiple heat-conducting piece.The heat produced when LED light source works can be passed on pedestal, and heat can promptly be passed on polylith fin by multiple heat-conducting piece by pedestal, and heat can promptly be passed in the external world by the surface finally by fin to be gone.

Although above-mentioned radiator also can play the effect of radiating and cooling, but the fin due to radiator is connected and installed on pedestal by heat-conducting piece, therefore in some cases, if heat-conducting piece deforms, polylith fin then can be caused close to each other, even polylith fin is close together mutually, not only affect the surface that air flows through fin, and the severe decrease area of dissipation of radiator, and then had a strong impact on the heat dispersion of radiator, make the heat dispersion of radiator unstable.

Utility model content

In order to solve the problem, the purpose of this utility model is to provide a kind of structure simple, and fin can not the close to each other or radiator that is close together simultaneously.

The utility model is the technical scheme that its technical problem of solution adopts:

A kind of LED lamp radiator, comprise one for installing the pedestal of light source, described pedestal is provided with multiple heat-conducting piece, each heat-conducting piece is provided with a fin, multiple fin interval forms a line, and multiple fin is provided with the changeless fixture of spacing between two fin keeping adjacent simultaneously.

As the improvement of technique scheme, described fixture is a long bolt, each fin all offers the screwed hole that can be used in combination with described long bolt.

As the further improvement of technique scheme, described fixture is a rectangular rod member that can pass multiple fin, this rectangular rod member is arranged with multiple distance piece laid respectively between two adjacent fin, the two ends of described distance piece can abut against by fin adjacent thereto respectively, described fin offer the through hole that described rectangular rod member can be allowed to pass.

In the utility model, described pedestal is also fixedly connected with one and encloses fixed frame in multiple fin periphery, and described fixture is fixedly arranged on described fixed frame.

Preferably, described fixed frame is also hinged with a handle.

The beneficial effects of the utility model are: because radiator of the present utility model is by forming a line multiple fin and adopting fixture by the spacing locking between adjacent two fin, thus make adjacent fin can not be close to each other or be close together, ensure that the spacing between abutting fins immobilizes, therefore heat can reject heat in external environment from fin better and go, and then makes radiator of the present utility model can have good heat dispersion.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Fig. 2 is another surface structure schematic diagram of the utility model one preferred embodiment;

Fig. 3 is the enlarged diagram at A place in Fig. 1.

Detailed description of the invention

With reference to Fig. 1 to Fig. 3, a kind of LED lamp radiator, comprise one for installing the pedestal 10 of light source 70, described pedestal 10 is provided with multiple heat-conducting piece 20, each heat-conducting piece 20 is provided with a fin 30, in the utility model, the heat produced when working to make light source 70 can be passed on fin 30 from pedestal 10 better, preferably, described heat-conducting piece 20 is super heat-conductive pipe, can more efficiently heat be passed on fin 30 from pedestal 10 by adopting super heat-conductive pipe, to improve the heat dispersion of radiator of the present utility model, multiple fin 30 interval forms a line, multiple fin 30 is provided with the changeless fixture 40 of spacing between two fin keeping adjacent simultaneously.

Because radiator of the present utility model is by arranging multiple fin row 30 one-tenth one and adopting fixture 40 by the spacing locking between adjacent two fin 30, thus make adjacent fin 30 can not be close to each other or be close together, ensure that the spacing between abutting fins 30 immobilizes, therefore heat can reject heat in external environment from fin 30 better and go, and then makes radiator of the present utility model can have good heat dispersion.

For the ease of the manufacturing of radiator of the present utility model, in the utility model, described fixture 40 is a long bolt, each fin 30 all offers the screwed hole that can be used in combination with described long bolt, therefore during fixing device for installing 40, only need to rotate the screwed hole on each fin 30 of long bolt precession, and make fin 30 be positioned at diverse location on long bolt, to be matched with the internal thread in the screwed hole on fin 30 by the apparent external screw thread of long bolt and act on, the position that fin 30 can be made to be positioned on long bolt immobilizes, and then the spacing between adjacent fin 30 is immobilized.

Certainly, above-mentioned fixture 40 can also adopt following structure: described fixture 40 is a rectangular rod member that can pass multiple fin 30, this rectangular rod member is arranged with multiple distance piece 41 laid respectively between two adjacent fin 30, the two ends of described distance piece 41 can abut against by fin 30 adjacent thereto respectively, described fin 30 offer the through hole that described rectangular rod member can be allowed to pass.By the two ends of distance piece 41 respectively fin 30 adjacent thereto abut against, two contiguous fin 30 equally also can be prevented close to each other or be close to, and then ensure the spacing between two adjacent fin 30.

Further, in order to reduce the stressed of fin 30, avoid foreign object to collide to fin 30, in the utility model simultaneously, described pedestal 10 is also fixedly connected with one and encloses fixed frame 50 in multiple fin 30 periphery, and described fixture 40 is fixedly arranged on described fixed frame 50.

Further again, for the ease of mobile radiator of the present utility model, preferably, described fixed frame 50 is also hinged with a handle 60, by this handle 60, user can mention radiator of the present utility model easily, and then can move radiator of the present utility model very like a cork.

The foregoing is only preferred embodiments of the present utility model, as long as the technical scheme realizing the utility model object with basic same approach all belongs within protection domain of the present utility model.
