Further, said heat conducting base is plate body.

Further, said radiator is the aluminium extruded type radiator.

Further, place outside the annulated column portion of said radiator and be provided with two above connection ribs, respectively this connection rib end supplies each said radiating part to connect respectively.

Further, place outside the annulated column portion of said radiator and also be provided with two above outer-finneds, and respectively this outer-finned is interspersed between any two adjacent said connection ribs.

Further, the annulated column portion of said radiator is provided with two above intussusceptums, supplies the condensation segment of each said heat pipe to wear.

Further, said intussusceptum is the C font.

Further, be provided with demarcation strip in the annulated column portion of said radiator, fin in these demarcation strip both sides further are provided with more than two.

Further, two above fin edge are equipped with in the radiating part periphery of said radiator.

Further, each said heat pipe is the U font.

Compared to prior art; The radiator structure of the utility model is located in respectively on the different radiating body through the condensation segment of two above heat pipes; Make and the effect that can reach samming between each heat pipe, cause the heating section of each heat pipe must cooperate its length of change simultaneously also because the position that wears is different through conduction of heat each other; Contact length so as to the heating section subsides adjacent one another are that increase each heat pipe reaches be heated average purpose and the effect that make between each heat pipe.

The specific embodiment

In order further to disclose the characteristic and the technology contents of the utility model, see also following detailed description and accompanying drawing, yet appended accompanying drawing is not to be used to limit to the utility model only as illustrative purposes about the utility model.

See also Fig. 1, be the perspective exploded view of the utility model.The utility model provides a kind of LED lamp cooling structure, comprises heat conducting base 1, two above radiators 2 and two above heat pipes 3, in order to the back side (promptly like Fig. 4 or shown in Figure 5) that is arranged on led light source 4, dispels the heat so as to helping this led light source 4; Wherein:

Please consult Fig. 2 in the lump, this heat conducting base 1 is processed by the good material of thermal conductivity usually, and like aluminium or copper etc., it is in order to be arranged on the above-mentioned led light source 4.This heat conducting base 1 have bottom surface 10 and with this bottom surface 10 back to end face 11.And in the embodiment that the utility model is lifted, this heat conducting base 1 is plate body, and its bottom surface 10 fits in order to the back side with led light source 4, is concaved with groove 110 on the end face 11, erects for above-mentioned heat pipe 3 to be arranged in the groove 110.

Please consult Fig. 3 in the lump; This radiator 2 can be the aluminium extruded type radiator; Groove 110 trends along above-mentioned heat conducting base 1 are transversely arranged, the radiating part 21 that this radiator 2 comprises hollow annulated column portion 20 respectively and is located on these annulated column portion 20 peripheries more than two, and can in this annulated column portion 20, be provided with demarcation strip 22; Can further be provided with the fin 220 more than two that also is positioned at annulated column portion 20 in these demarcation strip 22 both sides, so as to increasing area of dissipation; Simultaneously, two above fin edge 210 also can be equipped with in each radiating part 21 periphery, further promote radiating effect.Annulated column portion 20 is provided with the intussusceptum 200 that can be the C font more than two; And can outside annulated column portion 20, place and also be provided with two above connection ribs 201 and outer-finned 202; Said connection rib 201 is crisscross arranged in annulated column portion 20 peripheries with outer-finned 202; Each connection rib 201 end supplies radiating part 21 to connect respectively, and each outer-finned 202 is interspersed between any two adjacent connection ribs 201.
