Abstract

The utility model relates to a heat dissipation structure for an LED (light emitting diode) lamp, which is simple in structure, practical, and good in heat dissipation performance. The heat dissipation structure comprises a radiator and a heat conduction column, wherein the a groove is formed in the middle of the upper end of the radiator; a hollow body is arranged at the bottom end of the groove; the lower end of the heat conduction column is a bulge matched with the hollow body; the bulge is placed in the hollow body; the upper end of the bulge is combined with a shrouding disc; the upper end of the bulge of the heat conduction column is combined with a disc-shaped shrouding disc; the bulge of the heat conduction column is placed in the hollow body of the radiator to facilitate the heat conduction column to be fully contacted with the radiator; the shrouding disc is contacted with an ordinary LED or an aluminum substrate on the LED to increase the contact area of the heat conduction column and the LED or the aluminum substrate on the LED, in this way, the heat transferring and dissipation performance is improved. The heat dissipation structure is simple and practical.

Description

A kind of radiator structure

Technical field

The utility model relates to a kind of radiator structure, especially a kind of radiator structure of simple and practical, LED lamp that thermal diffusivity is good.

Background technology

In LED lamp field, because switching on, LED can send a large amount of heats when throwing light on, in order to prolong the life-span of LED lamp, usually can heat-transfer device be set at the periphery of LED, so that the heat that LED is sent distributes timely, thus the life-span of prolongation LED., heating column because with LED and LED substrate contacts area for cutting, usually can cause heat dispersion not so good.

The utility model content

The utility model is for the deficiencies in the prior art, and a kind of radiator structure of simple and practical, LED lamp that thermal diffusivity is good is provided.

The utility model is achieved through the following technical solutions:

A kind of radiator structure comprises radiator and heating column, and the middle part of described radiator upper end is provided with a groove, is provided with a hollow body in the bottom of this groove; Described heating column lower end is a projection that is complementary with this open tubular column, and this projection places in the described hollow body; Described projection upper end is combined with a shrouding disc.

As the further improvement of such scheme, described radiator is the graphite substrate structure.

As the further improvement of such scheme, described heating column is the metal base structure.

Further, described metal base is aluminium base.

As the further improvement of such scheme, described hollow body is hollow cylindrical body.

As the further improvement of such scheme, described shrouding disc is disc-shaped structure.

As the further improvement of such scheme, the diameter of described shrouding disc is greater than the hollow cylindrical body diameter.

The beneficial effects of the utility model are: the shrouding disc that is combined with a disc-shaped structure in the upper end of the projection of heating column, the projection of heating column places in the hollow body of radiator, heating column is fully contacted with radiator, and shrouding disc contacts daily LED or the aluminium base on the LED, can increase like this contact area of the aluminium base on heating column and LED or the LED, transmit and heat dispersion thereby improve.

Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to restriction of the present utility model.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is heat spreader structures schematic diagram of the present utility model;

Fig. 3 is heating column structural representation of the present utility model.

Wherein, 1 is radiator, and 2 is heating column, and 3 is groove, and 4 is hollow cylindrical body, and 5 is projection, and 6 is shrouding disc.

The specific embodiment

Can find out from Fig. 1, Fig. 2 or Fig. 3, a kind of radiator structure of the utility model comprises radiator 1 and heating column 2, and the middle part of described radiator 1 upper end is provided with a groove 3, is provided with a hollow cylindrical body 4 in the bottom of this groove 3; Described heating column 2 lower ends are a projection 5 that is complementary with this hollow cylindrical body 4, and this projection 5 places in the described hollow cylindrical body 4; Described protruding 5 upper ends are combined with the shrouding disc 6 of a disc-shaped structure.Described radiator is the graphite substrate structure; Described heating column is the aluminium base structure; The diameter of described shrouding disc 6 is greater than the diameter of hollow cylindrical body 4.

Be combined with the shrouding disc 6 of a disc-shaped structure in the upper end of the projection 5 of heating column 2, the projection 5 of heating column 2 places in the hollow cylindrical body 4 of radiator 1, heating column 2 is fully contacted with radiator 1, and shrouding disc 6 contacts daily LED or the aluminium base on the LED, can increase like this contact area of the aluminium base on heating column 2 and LED or the LED, transmit and heat dispersion thereby improve.This is simple and practical.

Certainly, when making heating column 2, can make solid or hollow body to the projection 5 on the heating column 2 according to actual needs, can improve and transmit and heat dispersion.

Below the utility model is described in detail, but apparent, those skilled in the art can carry out various changes and improvements, and does not deviate from the scope of the present utility model that appended claims limits.
