Embodiment
In conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
For the needs of explanation, exaggeration table is carried out to the width of some elements, length and thickness etc. in schematic diagram sometimes
Show.
As shown in Figures 1 to 4, a kind of high-power LED radiating structure, including shell 10, the radiating that is bonded with LED heat source 1
Bottom plate 2, heat conducting pipe, radiating fin 9, the shell 10 include the heat sink 8 with radiating groove 11, and the radiating fin 9 is set
It is placed within the cavity that the shell 10 encloses.The heat conducting pipe is divided into two kinds, and the first heat conducting pipe 6 is connected with radiating bottom plate 2
As welded, and axially extended in the heat sink 8, in the present embodiment, the heat sink 8 has two layers, the first heat conducting pipe 6
It is arranged between two layers of heat sink.Second of one end of heat conducting pipe 3 is connected with radiating bottom plate 2, and the other end vertically passes through each heat radiating fin
Piece 9.
As shown in figure 1, the shell 10 is shaped as six face columns, wherein at least two sides is heat sink.
As shown in Figures 2 to 4, the inclined-plane of top two of six face columns of the shell 10 and the inclined-plane of lower section two are radiating
Plate, middle two sides is supporting plate, with horizontal plane.The radiating fin is connected with the radiating bottom plate and hung down with horizontal plane
Directly.Radiating groove 11 and horizontal plane on the heat sink.In this way, the heat come is transferred out from radiating bottom plate is just divided into three
Two below the A areas radiating of individual region radiating, respectively intermediate radiator fin, the B areas radiating of two heat sinks of shell top and shell
The C areas radiating of heat sink.Comparatively, the thermal convection current in C areas is fastest.When the thermal convection current of C areas, hot-air rises, cold air
Heat sink sucks from below, drives the thermal convection current in A areas and B areas to accelerate, and can nature generation stack effect.Shell uses six face posts
Shape body configuration design, the radiating groove on the radiating fin and heat sink and horizontal plane, with sharp thermal natural convection from
Lower section suction radiating, ensures that hot-air produces quick thermal convection current through shortest path, accelerates thermal natural convection speed.
