Rapid Thermal Predictions for Automotive Headlamp Reflectors

This paper presents a methodology developed using Design of Experiments to predict the maximum temperature of an automotive headlamp reflector for the given geometry of the headlamp components and heat source. The proposed approach has been validated through comparison with three-dimensional Computational Fluid Dynamics simulation. The final out come of this study is a set of transfer functions, which can predict the maximum temperature of a reflector, positioned either in horizontal or vertical configuration.
