Effect of perforated pin-fin and plate-fin heat sinks on heat transfer enhancement: A review of recent literature

Pin-fin and plate-fin heat sink augmented the heat transfer for the internal combustion engine, the electronic system, the gas turbine blades, and other applications. This is due to its versatility, budget-free, and well-founded production processes. Generally, perforated heat sinks show a higher pressure drop when compared to other types of heat sinks. The present paper aims to summarize the benefits of perforation for the pin-fin and plate-fin heat sinks with laminar or turbulent flow. The influence of perforation size, number, shape, and orientation of the different heat sink for the heat transfer enhancement and pressure dropreported in recent literature is discussed.
