Thermal and hydraulic analysis of slotted plate fins heat sinks using numerical and experimental techniques

A heatsink's thermal and hydraulic performance can be optimized by making several modifications in the geometry. Modifying the heatsinks usually increases the weight by adding material. This study focuses on enhancing heat transfer by the removal of material in the form of slots. Fabrication of...
