Specific implementation mode
Further specific detailed description is made to the present invention in the following with reference to the drawings and specific embodiments.
As depicted in figs. 1 and 2, a kind of efficient radiating apparatus of high-power LED head lamp for motor vehicles, including heat pipe 4, deck 5,
One end of radiator 6, protective cover 1, radiator fan 7 and end cap 8, the radiator 6 connects radiator fan 7, and the other end is coaxially
The circle blind hole for being provided with cylinder boss and being connected with the cylindrical portion of the heat pipe 4 by tin cream Reflow Soldering, the circle blind hole
Inner wall make Nickel Plating Treatment, so that radiator and heat pipe is connect by tin cream Reflow Soldering better fixed.The end cap 8 uses
It being threadedly coupled or riveting is fixed on one end that radiator 6 connects radiator fan 7, the deck 5 is fixed on the cylinder boss,
For connection body.
The protective cover 1 is arranged outside heat pipe 4, and material is metal or high-temperature resistance plastice, and one end is solid by holding screw
Due on radiator 6, the gap slot for having and light being made to project is dug at the position of the LED lamp bead 2 relatively of the protective cover 1.Described
Heat pipe semi-finals degree is low, is easily damaged with transportational process manufacturing, and protective cover 1 shields, while protective cover 1 rises
Beauty function, it is exposed to be unlikely to internal circuit connection, and plays cooling effect to a certain extent.
As shown in figure 3, the heat pipe 4 includes cylindrical portion and both sides along its length fixes PCB by tin cream Reflow Soldering
The plat part of plate 3 is connected with LED lamp bead 2 on pcb board 3, and the 4 heat conduction thermal coefficient of heat pipe reaches 10000W/ (m
K more than).Heat conductivility is superior, effectively reduces the thermal resistance between copper-based pcb board and radiator.
The present embodiment is cylindric by the way that one end is arranged, and one end is flat heat pipe 4, is ensureing the same of heat exchange efficiency
When, because 4 flat part thickness of the heat pipe is small, the optically focused of LED headlamps is not influenced, meanwhile, the radiator 6 and the heat pipe 4
Cylindrical portion between, thermal resistance between the two is decreased between pcb board 3 and plat part by the way of tin cream Reflow Soldering, even
Stabilization is connect, it is not easily to fall off.
Tin cream reflow process between the cylindrical section of the heat pipe 4 and the circle blind hole of radiator 6 is：
Suitable tin cream is first filled to radiator 6 to justify in blind hole, then 4 cylindrical portion of heat pipe is inserted into the round blind hole, until
Cylinder end surface contacts the circle blind via bottom, then wipes a small amount of tin cream of spilling, is finally disposed vertically in reflow oven, carries out
Welding.The appropriate tin cream refers to after heat pipe 4 is inserted into circle blind hole, between tin cream fills up between heat pipe 4 and the circle blind hole of radiator 6
Gap, and overflow on a small quantity, gap can be not only tamped, but also non-welded part can be sticked to avoid tin cream waste or tin cream.Traditional LED vapour
Chinese herbaceous peony illuminator uses metal heat-conducting, and copper-based pcb board is placed on sheet metal, although sheet metal and radiator 6 are integrated,
It being not in contact with thermal resistance, but foil cross-section product is small, thermal resistance is big, causes the temperature difference between LED lamp bead 2 and radiator 6 very big,
It is unfavorable for radiating；Although and have thermal contact resistance between heat pipe 4 and radiator 6 because using solder connect, can subtract significantly
Small thermal contact resistance, while the heat conductivility of heat pipe 4 is superior, effectively reduces thermal resistance, reduces the temperature difference of LED lamp bead 2 and radiator 6,
The junction temperature for advantageously reducing LED lamp bead 2, prolongs the service life.
The radiator fan 7 is holder fan, is fixed on 6 one end of radiator by screw.Since radiator fan 7 is fixed
It in 6 end of radiator, rather than is embedded in as the prior art in radiator 6, therefore, the radiator length reduces, material
Expect cost reduction, while processing cost also reduces.The high-speed rotation of the radiator fan 7 is accelerated empty around heat radiator fin
Flow of air rate takes away the heat on 6 surface of radiator so that the junction temperature of LED lamp bead 2 is kept in allowed limits.
As shown in figure 4, the radiator 6 is heronsbill radiator, material is aluminium alloy, by extrusion process is processed
At heat conductivility is good, simple for process, and fin is arc, is conducive to increasing heat radiation area, the surface of curved fins is provided with
Axial raised structures are parallel to, flow-disturbing can be formed simultaneously with increasing heat radiation area, increase convection transfer rate, be conducive to dissipate
Heat, meanwhile, the raised structures are parallel to axial direction, are also convenient for the extrusion forming in radiator.The periphery wall of the circle blind hole
It is provided with the through-hole in the channel as LED lamp bead conducting wire, conducting wire is made to be unlikely to exposed, plays beautification function.In addition, due to radiation air
Fan 7 is fixed on 6 end of radiator, rather than is embedded in as the prior art in radiator 6, therefore, the radiator length
Reduce, material cost reduces, while processing cost also reduces.
The above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be to the present invention
Embodiment restriction.For those of ordinary skill in the art, it can also make on the basis of the above description
Other various forms of variations or variation.There is no necessity and possibility to exhaust all the enbodiments.It is all the present invention
All any modification, equivalent and improvement etc., should be included in the protection of the claims in the present invention made by within spirit and principle
Within the scope of.
