THERMAL AIR FLOW ANALYSIS OF AN AUTOMOTIVE HEADLAMP

An automotive headlamp which is necessary for nighttime driving was used as only a safety part in the past, but, latest headlamps are increasingly required not only to be a function but also to enhance a design of an automobile. These new demands make a headlamp complicated in structure, therefore, if heat transfer and flow inside a headlamp can be predicted in a design stage using the Computational Fluid Dynamics (CFD), a deformation of plastic parts by heat can be avoided, and a misting problem on a lens due to humidity control performance of plastic parts can be also predicted. As a result, this will enable to shorten a development period. In this paper, a newly-developed method called surface heat transfer (SHT), a unique technique for making an accurate estimation of temperature and velocity in an automotive headlamp without involving the use of "fluid mechanics and structure mechanics, were investigated for practical use.
