Optimal plate-fin design for improving heat dissipation performance of automobile lamp reflectors

Basic analyses were conducted upon an existing headlamp, and the validity of the analytical model was verified by testing existing reflector temperatures under conditions similar to those modeled during the analyses. Based on this verification, three types of radiating fins were modeled and analyzed. The vertical fin type exhibited the highest heat dissipation performance. Subsequently, design variables were selected for the vertical fin type and size optimization was performed using the design of the experiment model. Results confirmed a heat dissipation performance increase of 4.5% relative to the existing model. | Optimal plate-fin design for improving heat dissipation performance of automobile lamp reflectors
