Description
Technical field
The present invention relates to wiring board design manufacturing technology field, is concretely a kind of liquid-cooling heat radiation automobile LED headlight mould
Group.
Background technology
LED car lamp is because of its unique advantage：It is energy saving, service life is long, shock resistance is strong, it is fast to light speed, loss is low, load
It is small etc., in the automobile market use of comprehensive importing taillight, steering indicating light, brake lamp fog lamp.
The headlight of automobile market, which also has progressively to import, at present uses LED light, therefore the whole LED module of headlight is dissipated
Hot property is most important, and the heat dissipation performance of module determines the service life of product.
Traditional headlight module manufacture craft is that circuit base plate and cooling stand are carried out group using metal cold riveting or screw
Dress, fasten to realize such as Fig. 5, and increase small-sized fans outside cooling stand after connection carries out cooling processing to whole module, makes LED
The heat produced in use is by circuit base plate and cooling stand by heat derives.Due to this technique circuit base plate with
In cooling stand assembling process, both cannot fully be bonded, and gap is formed among circuit base plate and cooling stand causes LED to be produced
There is missing in raw heat conduction, heat conductivility substantially reduces.
For this problem, in order to make coming into full contact with for circuit base plate and cooling stand, now often in metal cold riveting or spiral shell
The technique that the anterior branch of silk fastening is filled using heat-conducting silicone grease, though such a technology mode connects circuit base plate and cooling stand
Tactile reliability makes moderate progress raising, but overall heat conductivility can not improve completely, because of the thermal conductivity of heat conductive silicon grease material
There are limitation, the whole radiating requirements of LED car lamp can not be fully met.
In short, the heat dissipation performance of existing automobile LED car light module is also limited to cooling stand and fan.
Design for this it is a kind of it is brand-new be extremely to be necessary using the quick heat radiating automobile LED headlight module of liquid radiating
's.
The content of the invention
The present invention breaches the problem of the prior art, devises a kind of brand-new quick heat radiating automobile using liquid radiating
LED headlight modules.
In order to achieve the above object, the present invention devises a kind of liquid-cooling heat radiation automobile LED headlight module, including：Metal Substrate
Plate, LED components, heat dissipation water tank, it is characterised in that：LED components are fixed with metal substrate and form circuit base plate, water of radiation
Groove is internally provided with a circle depth positive stop strip, and the bottom of heat dissipation water tank is fixed with radiating fin, four apex angles of depth positive stop strip
On offer mounting-positioning holes.
The altitude range of the depth positive stop strip for circuit base plate thickness 4 ~Times.
The width of the heat dissipation water tank and being of same size for circuit base plate.
Compared with prior art, the present invention by the way of liquid injection, circuit base plate is set to be come into full contact with cooling stand,
And liquid plays heat absorption and conductive force, the heat that circuit base plate during use is produced absorbs export and passes through heat dissipation in time
Heat is completely exhausted out by stent, and circuit base plate and cooling stand are seamlessly connected by the present invention, and reduce the use of radiator fan,
Reduce production cost.
Brief description of the drawings

Fig. 2 is the structure diagram of cooling stand in the present invention.
Fig. 3 is the structure diagram of the present invention.
Fig. 4 is the sectional view of the present invention.
Fig. 5 is the structure diagram of the prior art.
Referring to Fig. 1 ~ Fig. 4,1 is metal substrate, and 2 be LED components, and 3 be heat dissipation water tank, and 4 be depth positive stop strip, and 5 be scattered
Hot fin, 6 be mounting-positioning holes.
Embodiment
With reference to attached drawing, the present invention is described further.
Referring to Fig. 1 ~ Fig. 4, the present invention devises a kind of liquid-cooling heat radiation automobile LED headlight module, including：Metal substrate, LED
Component, heat dissipation water tank, it is characterised in that：LED components 2 are fixed with metal substrate 1 and form circuit base plate, heat dissipation water tank 3
Be internally provided with a circle depth positive stop strip 4, the bottom of heat dissipation water tank 3 is fixed with radiating fin 5, four tops of depth positive stop strip 4
Mounting-positioning holes 6 are offered on angle.
In the present invention altitude range of depth positive stop strip 4 for circuit base plate thickness 4 ~Times, circuit base can not be exceeded
Plate.
The width of heat dissipation water tank 3 and circuit base plate is of same size in the present invention.
In specific implementation, LED components and parts assemblings are fixed on metallic substrates first, forms circuit base plate, then will
Cooling stand is completed using injection, control circuit substrate, is put its back side is parallel to the heat dissipation water tank of cooling stand, is used weldering
Surrounding gap after material combines circuit base plate with cooling stand carries out edge sealing processing, and circuit base plate is combined envelope with cooling stand
Injected liquid into behind side by the way of automatic liquid-feeding so that liquid comes into full contact with circuit base plate.
In specific implementation by taking metal substrate is copper base as an example：
When copper-based plate thickness is 1-3 MM, using sink volume≤200*200*200 MM, low boiling point≤90 DEG C liquid,
It is 5-1000W to make heat radiation power controlled range, accelerates radiating efficiency, the present invention in specific implementation can be according to different metal base
Material, size, thickness and the cooling requirements of plate, the appropriate relevant parameter for adjusting the above.
