Preferably, the bottom of described platform is provided with fan installing hole.
Preferably, the fin of described fin diminishes gradually from middle part to the both sides of platform of platform.
Preferably, the front side away from LED light source of described reflector positioning table is provided with buttcover plate, and buttcover plate is provided with sleeve locating dowel and sleeve installing hole; The protrusion of described reflector positioning table is provided with radiator location-plate on the plate face of described platform.
Preferably, described buttcover plate is set to two, and two buttcover plates divide along the center line symmetry of described platform the both sides that are located at platform; The front side away from LED light source of described platform is respectively arranged with the first plate washer locating dowel and the second light barrier locating dowel, and the rear side of platform is provided with attaching plug installing hole.
Preferably, radiator is that die casting is one-body molded.
Beneficial effect of the present invention is:
1) radiator, in the present invention is aluminum alloy material, and radiating effect is good; In addition, between adjacent fin, be provided with gap, this set has increased area of dissipation, has improved radiating efficiency, has further improved radiating effect; The horizontal partition grooves arranging on fin has been guaranteed the circulation of air in the small space of car light inside, has ensured timely heat radiation.Therefore, the present invention has all guaranteed radiating effect in material and structure aspects, has therefore ensured, in the working environment of headlight for vehicles in safety and stability, to have extended widely the service life of headlight for vehicles.
2), the present invention is provided with fan installing hole in the bottom of platform, in the time that radiator is worked, on the one hand by fin heat loss through radiation, logical by fan forced air flow on the other hand, and carrying out heat loss through convection by the horizontal partition grooves on fin, the present invention's radiator more of the prior art has greatly improved radiating efficiency thus.
3), the present invention arranges reflector positioning table at the sidepiece of platform, be provided with in the front side of reflector positioning table for the joining buttcover plate of sleeve, on plate face at the protrusion of reflector positioning table at platform, be provided with radiator location-plate, the present invention is also provided with in the front side of platform and the joining locating dowel of light barrier, and be provided with attaching plug installing hole at the rear side of platform, therefore LED light source, reflector, light barrier, sleeve, fan and attaching plug can directly be fixed on radiator, and above-mentioned parts have all been avoided the main heat dissipation direction of radiator, therefore heat spreader structures of the present invention has not only been simplified installation steps, and installation accuracy and the radiating efficiency of product are farthest ensured.
4), this radiator is that die casting is one-body molded, farthest reduced thermal resistance, improved radiating efficiency.
