Heat-radiation belt bottom is stated outside radiating shell, the fan provided with blow-through heat conducting pipe and heat-radiation belt junction in the radiating shell,
Described radiating shell is described to assure parcel heat conducting pipe top provided with assuring, the radiating shell provided with heat dissipation grid or
Radiate flower pattern part.
As a preferred embodiment, the radiating shell includes protecgulum, center and bonnet, the protecgulum, center and bonnet connection
A cavity volume is formed, the fan and heat conduction pipe end are in cavity volume, and the radiating shell is provided with convection current passage.
It is preferred that, the protecgulum be provided with air admission hole, center both sides be provided with breach, after cover provided with and air admission hole formation convection current
Venthole.
It is preferred that, described assuring is combined into and is respectively arranged on protecgulum and center for two semicanals.
The beneficial effects of the invention are as follows：A part of heat is transmitted to heat-radiation belt using heat conducting pipe, heat-radiation belt physics is utilized
Radiating, another part is transferred to shell by assuring, and the heat dissipation grid or radiating flower pattern part of the design on shell are accelerated physics and dissipated
Heat, fan directly cools to the high temperature bond point that heat conducting pipe and heat-radiation belt are connected while accelerating radiating shell radiating, radiating shell
The convection current stomata being provided with so that circulation is formed in airflow radiating housing, accelerates junction radiating, and the power of lamp bead can also be because
Raising for the efficiency that cools can be improved further, so that the brightness after LED product increase power is higher, reach driving peace
Full illuminating effect.
Brief description of the drawings
Fig. 1 is the stereogram of the present invention.
The structure that Fig. 2 is the present invention splits schematic diagram.
In figure：1. the heat-radiation belt 4. of 2. heat conducting pipe of radiating shell 3. assures the bonnet of 5. fan, 6. protecgulum, 7. center 8.
9. the air admission hole of 11. venthole of heat dissipation grid, 12. breach 13..
Embodiment
With specific embodiment, the invention will be further described below in conjunction with the accompanying drawings, with reference to Fig. 1-2, before a kind of LED automobile
Headlight heat radiation structure, including radiating shell 1 and heat conducting pipe 2, radiating shell 1 are good heat dissipation effect, and the high metal of cost performance is cast,
The end of heat conducting pipe 2 is connected with heat-radiation belt 3, and heat conducting pipe 2 and the junction of heat-radiation belt 3 are arranged in radiating shell 1, the bottom of heat-radiation belt 3
Outside radiating shell 1, the fan 5 of blow-through heat conducting pipe 2 and the junction of heat-radiation belt 3 is installed in radiating shell 1, fan 5 is straight
Junction is blown to cool to it.Be communicated with radiating shell 1 possess heat-conducting effect assure 4, assure 4 and be wrapped in heat conducting pipe 2
Radiating shell 1 is passed through with the periphery of outer portion, the partial heat of heat conducting pipe 2 is conducted to radiating shell 1, passes through radiating shell
The heat dissipation grid 9 designed on 1 is radiated.Radiating shell 1 is assembled by protecgulum 6, center 7 and bonnet 8, and it forms one
Cavity volume, fan 5 and the end of heat conducting pipe 2 are arranged in cavity volume, and convection current passage is designed with radiating shell 1.Protecgulum 6 is provided with
The air admission hole 13 of flower pattern, simultaneously, flower type structure also possesses certain radiating effect for ventilation, and the both sides of center 7 are provided with breach 12, bonnet
8 are provided with the venthole 11 with the formation convection current of air admission hole 13.4 are assured to be combined into for two semicanals and be respectively arranged on protecgulum 6 and center 7
On, and assure 4 and radiating shell 1 be integrated and cast, heat-conducting effect is good.
When in use, LED lamp bead connection heat conducting pipe 2, the heat-radiation belt connected to end is led by copper heat conducting pipe 2 by heat
On 3, on the one hand cooled by heat-radiation belt 3, another aspect heat conducting pipe 2 and the connection position of heat-radiation belt 3 are equipped with fan blow-through, by dissipating
The design of convection current passage on hot housing 1, air ring is around junction so that with more preferable radiating effect, assures 4 hard-pressed bales and is leading
On heat pipe 2, a part of heat on heat conducting pipe 2 is conducted to radiating shell 1, passes through the radiating lattice designed on radiating shell 1
Grid 9 are further radiated, and the fan 5 being arranged in radiating shell 1 cools simultaneously to junction, also accelerates radiation shell
The radiating of body 1.The circuit outlet room provided with lamp bead and fan on aluminium radiating shell 1 so that power line is more reasonably laid out
Install.In addition, heat dissipation grid or radiating flower pattern part are not solely restricted to the bonnet 8 being designed at shown in Fig. 2 on radiating shell 1
On, it can equally design in the inner side of radiating shell 1, the similar design for accelerating radiating by the structure should be regarded as present invention protection model
In enclosing.The present invention is by heat conducting pipe 2 and assure 4 heat is dispersed on heat-radiation belt 3 and radiating shell 4, by heat-radiation belt 3 and dissipates
The hot heat dissipation design of housing 4 carries out physics radiating simultaneously, and the design for the fan 5 being inside located in radiating shell 1 cools together to junction
When radiating shell 1 is cooled, air ring is around junction and through space in radiating shell 1, with more preferably radiating effect.
The LED lamp bead power of the invention in actual use is up to 30W ± 3W, its lamp bead boundary temperature up to 84 ± 5
, the temperature of heat-radiation belt is reduced to 45 ± 5 so that the light decay of lamp bead is slower, and the life-span is longer, relatively of the invention, other products
The lamp bead for being only capable of meeting power in 18W-25W works, and lamp bead nearby temperature in 95-110 or so, heat-radiation belt temperature 75 with
On, lamp bead is also due to radiating is bad, its lost of life and light decay is very fast.If accomplishing that lamp bead power accomplishes 30W or so, it is produced
Product can not be used normally.Therefore excellent in heat dissipation effect of the present invention, disclosure satisfy that the lamp bead radiating requirements improved after power, so that
The LED product life-span is longer, and the brightness after increase power is higher, while also reaching the illuminating effect of traffic safety.
