Review on design and heat transfer analysis of solid and perforated fins for the enhancement of thermal performance of heat sinks

Abstract

Fins are used to enhance the heat transfer of heat sinks. Few of the researchers had been studied and analyzed the performance of rectangular or longitudinal fins and pin fins. Also many of the researchers studied the experimentally or/and computationally or/and analytically heat dissipation performance analysis of solid and perforated fins. Also shown the staggered arrangement of fins is more suitable than the in-line arrangement. A review is carried out on thermal performance of various designs of solid and perforated fins and reports the advantages of perforated fins over solid fins and the applications of perforated fins in the area of IC Engines, electronics heat sinks, aircraft, heat exchangers etc. In this paper, summarizes the investigated efforts taken by the researchers for the design and developments of solid and perforated fins for the enhancement of thermal performance of heat sinks.
