Description
Technical field
The utility model relates to a kind of LED automobile lamp, specifically provides a kind of heat abstractor of LED automobile lamp.
Background technology
LED automobile lamp has obtained and has used widely in range of application, and the requirement of people to LED automobile lamp is also more and more higher, and the performance due to LED automobile lamp directly has influence on the safety of driving, so require that LED automobile lamp has specular removal and long-life.But high-power light source will produce a large amount of heats in use, and fall apart these heats not in time, will have a strong impact on light efficiency and the life-span of light fixture.
Summary of the invention
The purpose of this utility model is to provide a kind of radiating effect LED automobile lamp heat abstractor remarkable, easy for installation.
The technical scheme that the utility model provides is:
A kind of heat abstractor of LED automobile lamp, comprise case and heat sink, the back side array of described heat sink is fixed with radiating fin and condenser pipe, heat sink is hollow sheeting, described condenser pipe one end connects the upper end of heat sink, the other end connects the lower end of heat sink, and condenser pipe runs through radiating fin, condenser pipe is connected micro-compressor and fluid reservoir.
Described fluid reservoir storage liquid nitrogen or freon.
Also comprise thermistor and fan, thermistor is fixed on the upper end of heat sink, and fan is fixed on the inwall of case, and power line connects fan after thermistor.
LED automobile lamp of the present utility model by increasing heat sink surface area, thus improves the effect of heat radiation; And cooled by condensing agent, reduce the operating temperature of LED automobile lamp; And the flow velocity of air is accelerated by fan, improve the efficiency of heat exchange, reduce the operating temperature of LED automobile lamp, ensure that the operating temperature of LED automobile lamp controls, in suitable scope, to improve the working life of LED.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, a kind of heat abstractor of LED automobile lamp, comprises case 5 and heat sink 10, case 5 is fixed in LED 1, the back side array of heat sink 10 is fixed with radiating fin 9 and condenser pipe 7, and radiating fin 9 can play the area increasing and contact with air, thus can better dispel the heat; In order to further increasing heat radiation area, described heat sink 10 and radiating fin 9 adopt blasting treatment, and blasting treatment can make the surface attachment layer of metal particle of heat sink 10 and radiating fin 9, thus increasing heat radiation area.
When the radiating efficiency of heat sink 10 and radiating fin 9 is not enough to the operating temperature reducing LED automobile lamp, the utility model is also provided with condenser pipe 7, micro-compressor 6 and fluid reservoir 8, heat sink 10 is hollow sheeting, described condenser pipe 7 one end connects the upper end of heat sink 10, the other end connects the lower end of heat sink 10, condenser pipe 7 runs through radiating fin 9, condenser pipe 7 is connected micro-compressor 6 and fluid reservoir 8.Fluid reservoir 8 stores the condensing agent such as liquid nitrogen or freon.When micro-compressor 6 is started working, from fluid reservoir 8, extract condensing agent, condensing agent enters radiating fin 9 and heat sink 10 by condenser pipe, and the heat taken away wherein gets back to fluid reservoir 8, thus plays the effect of cooling.
In order to better dispel the heat to condenser pipe 7, fix a fan 4 at the inwall of case 5, this fan is controlled by thermistor 2, and described thermistor 2 is arranged on the upper end of described heat sink 10, and power line 3 connects described fan 4 after described thermistor 2.After temperature reaches certain value, thermistor 2 path, touches and fan 4 is started working, and increases air circulation, accelerates cold-hot air convection, thus plays to the effect of condenser pipe 7, heat sink 10 and radiating fin 9 heat radiation.
Described embodiment is preferred embodiment of the present utility model; but the utility model is not limited to above-mentioned embodiment; when not deviating from flesh and blood of the present utility model, any apparent improvement that those skilled in the art can make, replacement or modification all belong to protection domain of the present utility model.
