Abstract
The utility model discloses a kind of LED lamp heat sink, including radiator body, radiator body is in straight-tube shape, its internal accommodating chamber with being placed in for LED, having outside the radiator body has multiple heat emission holes on multiple radiating fins, the radiating fin.Compared with prior art, the utility model structure is very simple, it is efficient to radiate, and can be prevented effectively from LED overheat, increase the service life.
Description
Technical field
The utility model is related to a kind of LED lamp heat sink.
Background technology
LED lamp heat sink of the prior art is complicated, and radiating effect is poor.
Utility model content
In view of this, technical problem to be solved in the utility model is：A kind of simple in construction and good heat dissipation effect is provided
LED lamp heat sink.
In order to achieve the above object, the utility model adopts the following technical scheme that to realize：
A kind of LED lamp heat sink, including radiator body, radiator body are in straight-tube shape, and it is internal with for LED appearance
It is placed in have outside interior accommodating chamber, the radiator body and there are multiple radiatings on multiple radiating fins, the radiating fin
Hole.
Preferably, the radiator body is formed by the bending of a piece of fin, have in the middle part of the radiator body
Circular accommodating chamber, the outside radiating fin with a plurality of rectangle parallel with axis, each radiating fin form described dissipate
Hot device body rounded outer profiles.
Preferably, the radiator body has internal layer heat-sink shell, outer layer heat dissipating layer and intermediate heat layer, the internal layer
Heat-sink shell is iron layer, and outer layer heat dissipating layer is aluminium lamination, and the heat transfer layer is nickel dam, and three's thickness is respectively：Iron layer 1MM, nickel dam
0.2MM, aluminium lamination 2MM.
Preferably, the outer layer heat dissipating layer on each radiating fin is outward extended with 50 to 100 straight-bars
Interval is respectively provided between shape radiating pin, the adjacent radiating pin.
As shown from the above technical solution, the beneficial effects of the utility model are：
Compared with prior art, the utility model is by the way that by fansink designs, into straight-tube shape, structure is very simple, by by one
The bending of piece fin is formed, and further having simplified on its structure, radiating fin, there are multiple heat emission holes can effectively improve scattered
Thermal effect, the radiating fin of rectangle is formed by then passing through bending, and it is middle between hollow appearance, and further raising radiating is imitated
Really, and rectangle area of dissipation it is bigger.The structure bent by a piece of fin fills shaping compared to other notes or is welded to connect
Mode, manufacturing process carries out note without hot melt material and fills shaping, and during the structure of especially three composite beds, the fusing point of each material is not
Together, the cooperation between composite bed is more favorable for by way of bending when being made by mixing.By being designed to iron layer 1MM, nickel dam
0.2MM, aluminium lamination 2MM, substantially increase radiating effect, further, and it is by the design of the pin that radiates, by each radiating fin
Radiating value is significantly improved, and radiating is efficient, can be prevented effectively from LED overheat, be increased the service life.
Brief description of the drawings
Fig. 1 is end face structure schematic diagram of the present utility model.
Embodiment
In order that those skilled in the art can be further understood that feature of the present utility model and technology contents, refer to
Down about detailed description of the present utility model and accompanying drawing.
Refer to shown in Fig. 1, the utility model provides a kind of LED lamp heat sink, including radiator body 1, radiator
Body is in straight-tube shape, its internal accommodating chamber 2 with being placed in for LED, is had outside the radiator body multiple scattered
There are multiple heat emission hole (not shown)s on hot fin 3, the radiating fin.
Preferably, the radiator body is formed by the bending of a piece of fin, have in the middle part of the radiator body
Circular accommodating chamber, the outside radiating fin with a plurality of rectangle parallel with axis, each radiating fin form described dissipate
Hot device body rounded outer profiles.
Preferably, the radiator body has internal layer heat-sink shell, outer layer heat dissipating layer and intermediate heat layer, the internal layer
Heat-sink shell is iron layer, and outer layer heat dissipating layer is aluminium lamination, and the heat transfer layer is nickel dam, and three's thickness is respectively：Iron layer 1MM, nickel dam
0.2MM, aluminium lamination 2MM.
Preferably, the outer layer heat dissipating layer on each radiating fin is outward extended with 50 to 100 straight-bars
Interval is respectively provided between shape radiating pin (not shown), the adjacent radiating pin.
But preferable possible embodiments of the present utility model are the foregoing is only, and are not used to limit to patent of the present utility model
Scope, therefore the equivalent structure change that all utilization the utility model specifications and accompanying drawing content are made, are similarly included in this practicality
In new scope.
