AUTOMOBILE HEADLIGHT WITH PHASE-CHANGE-INHIBITING SHEET RADIATOR

摘要

An automobile headlight with a phase-change-inhibiting sheet radiator comprises a fan (1), a radiator assembly (2), and an LED light source (3). The radiator assembly comprises at least a phase-change-inhibiting sheet radiator (21), the fan being arranged at an end of the radiator assembly, and the LED light source being installed on the radiator assembly. By replacing a conventional incandescent light bulb with an LED light source, the light efficiency of the automobile headlight with a phase-change-inhibiting sheet radiator is effectively improved. The phase-change-inhibiting sheet radiator has the characteristic of rapid heat conduction, and has a uniform temperature on the surface of the radiator, and a temperature difference between the surface of the radiator and the air is relatively great, which multiplies a heat radiation amount compared with a conventional aluminum radiator. By replacing an aluminum radiator in the prior art with a phase-change-inhibiting sheet radiator, heat generated by an LED light source can be rapidly conducted to a remote end, and heat exchange with the air is accelerated by using a fan to force cross-ventilation, thereby resolving the problem of a large light failure and a short life of an automobile headlight, and improving the energy efficiency ratio of the automobile headlight.
