Bright idea for headlights

September 08, 2017 // By Ansys
Momentive Performance Materials (Momentive) has developed thermal pyrolytic graphite (TPG), a new material that provides four times the thermal conductivity of copper at one-fourth the weight. The company set out to develop new heat sink designs that could improve the performance of current LED headlights. Building and testing a single prototype would take weeks of effort and many prototypes to optimize the design, but by leveraging the use of ANSYS Fluent computational fluid dynamics (CFD) software, Momentive engineers were able to accurately predict the performance of alternative thermal management designs in only 15 minutes.
