Optimization of chimney design for an extruded radial heat sink using experiments and neural network models

This study investigates chimney-assisted natural-convection cooling for an Extruded Radial Heat Sink (ERHS) in high-power Light Emitting Diode (LED) applications. Although chimneys have been applied to Forged Radial Heat Sinks (FRHSs), their application to ERHSs remains insuffici...
