Background technology
Today's society, the popularity rate of LED automobile headlamp are gradually incremented by；For car owner, almost everybody wants to possess a set of energy
The higher LED headlights of degree of opinion.But when LED headlights are in running order, temperature is an important indicator, the big light temperatures of LED
It is higher, on influenceing to degenerate therewith caused by the performance of LED headlights.So, cooling processing is carried out to LED headlights and seems particularly heavy
Will.At present in LED headlights, although there is the common radiator carried, it can not many times be really achieved LED headlights and dissipate
The requirement of heat drop temperature, such as：The constantly work for a long time daily of LED headlights, the raising of ambient temperature（Summer）Deng can all make
It is higher into temperature, so that LED headlights are difficult to have higher visibility.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of LED automobile headlamp temperature-control ice cold heat sink, heat dispersion is strong,
The temperature of LED automobile headlamp is effectively reduced, ensures its normal use, extends its service life.
In order to solve the above-mentioned technical problem, the present invention takes following technical scheme：
A kind of LED automobile headlamp temperature-control ice cold heat sink, including radiator, the radiator is interior to be provided with installation cavity, radiator bottom
Face is equipped with the radiator fan connected with installation cavity, and cool guide sheet is installed in installation cavity, and the upper surface of the installation cavity is used to install band LED
The aluminium base of lamp, cool guide sheet upper surface contact with aluminium base.
Heat insulation foam, cool guide sheet and the heat insulation foam attaching are equiped with the installation cavity.
The side of the heat insulation foam is provided with engaging lug, and the side of cool guide sheet is provided with mounting ear, the mounting ear alignment of cool guide sheet
It is fitted on the engaging lug of heat insulation foam and passes through screw locking.
Electronics heat absorbing sheet is additionally provided with the installation cavity, the electronics heat absorbing sheet contacts with heat insulation foam.
Installation through-hole is provided with the heat insulation foam, electronics heat absorbing sheet is mounted in the installation through-hole, and the electronics heat absorbing sheet
Upper surface contacted with cool guide sheet lower surface.

Accompanying drawing 3 is the present invention and the decomposition texture schematic diagram after LED assembling.
Embodiment
For the feature of the present invention, technological means and the specific purposes reached, function can be further appreciated that, with reference to
Accompanying drawing is described in further detail with embodiment to the present invention.
As shown in figure 1 and 2, present invention is disclosed a kind of LED automobile headlamp temperature-control ice cold heat sink, including radiator 2,
Installation cavity 3 is provided with the radiator 2, the bottom surface of radiator 2 is equipped with the radiator fan 1 connected with installation cavity 3, and installation cavity 3 is built-in
If cool guide sheet 8, the upper surface of the installation cavity 3 is used to install the aluminium base 9 with LED, and the upper surface of cool guide sheet 8 connects with aluminium base 9
Touch.Aluminium base 9 to is sent cold by cool guide sheet 8, plays thermolysis, reduces the temperature of aluminium base, while aluminium base is again
Heat can be returned to cool guide sheet, radiator fan takes away the heat on cool guide sheet, maintains the low temperature of cool guide sheet.
Heat insulation foam 6, cool guide sheet 8 and the attaching of heat insulation foam 6 are equiped with the installation cavity 3.The side of heat insulation foam 6, which is provided with, to be connected
Lug 5, the side of cool guide sheet 8 are provided with mounting ear 7, the mounting ear alignment of cool guide sheet 8 be fitted on the engaging lug of heat insulation foam 6 and
Pass through screw locking.The assembling of heat insulation foam and cool guide sheet is realized using screw, is mounted and dismounted all more convenient.
In addition, being additionally provided with electronics heat absorbing sheet 4 in installation cavity 3, the electronics heat absorbing sheet 4 contacts with heat insulation foam 6.Utilize the electronics
Heat absorbing sheet, preferably the heat of cool guide sheet can be absorbed, and then distributed, keep the low temperature of cool guide sheet.
Installation through-hole is provided with the heat insulation foam 6, electronics heat absorbing sheet 4 is mounted in the installation through-hole, and the electronics absorbs heat
The upper surface of piece contacts with cool guide sheet lower surface, and assembling is even closer.
The aluminium base is connected by screw and cool guide sheet locking.
The radiator fan 1 is arranged on radiator bottom surface by blower tray 10.Radiator is provided with some fin, this
For common knowledge, in this not go into detail.
As shown in Figure 3, on the basis of radiator, whole light fixture is assembled.Optical lens is installed in the front end of radiator 2
12, on aluminium base 9 lid dress reflector 11, the reflector by screw locking on a heat sink.During whole light fixture work, pass through
Cool guide sheet, cold is sent on the aluminium base where LED, can reach the purpose that radiating refrigeration is provided LED, to ensure
LED can for a long time be maintained under low-temperature condition and work, so as to improve the efficiency of LED and life-span.Pass through electronics heat absorbing sheet
Heat on cool guide sheet is constantly suctioned out, being combined closely with radiator makes heat be sent on radiator again by radiator fan handle
