It is important to understand the heat transfer and flow in an automotive headlamp in order to improve heat proof ability, durability and ventilation performance. Especially in the disign stage, understanding thermal air flow inside the headlamp will make it possible to shorten its development period, which can be fulfilled by Computational Fluid Dynamics (CFD) technique. In the present study, a newly-developed method called surface heat transfer (SHT), that is a unique technique for making an accurate estimate of temperatures in the automotive headlamp without coupling fluid and structural mechanics, was investigated for practical use. An evaluation of CFD results was performed and compared with the experimental results. Consequently, the temperature results by CFD were within ±10 degrees as compared with the experimental results.
