Thermal enhancement from heat sinks by using perforated fins

An experimental and computational investigation of thermal air flows through perforated pin heat sinks

“…Most studies have examined the benefits of perforating plate fins. Shaeri & Yaghoubi [15,16] and Shaeri & Jen [17,18], for example, studied the effect of the number of perforations and their size, while Farhad Ismail et al [19,20] considered the influence of perforation shape, on heat transfer and frictional drag on the air for both laminar and turbulent flow cases. Shaeri & Jen [17,18], for example, found that a single perforation in a plate fin could increase the heat transfer rate by up to 80%.…”

Optimization of a rectangular pin fin using rectangular perforations with different inclination angles

“…To show the advantages of the perforation, [3] shows The thermal profile of the perforated fins in a staggered manner performs better than the solid elliptical pin fin according to the Static temperature, Nusselt number and total heat that is calculated. The effects of the porosity on the performance of the fins were investigated by [4,5]for longitudinal and lateral perforation. Rectangular cross section with different dimensions and multi numbers of the perforation was considered to show the thermal enhancement at various operating conditions.…”

Experimental Study of Performance of Pin Fin Heat Sink under Forced Convection

“…In a study performed by Tahat et al [10] in a channel with rectangular cross section equipped with needle fins, the effects of the distance between fins, the space above them and their in-line and staggered arrangement on heat transfer were investigated experimentally. Shaeri and yaghoubi [11] investigated thermal performance of three dimensional incompressible laminar flow from heat sinks by using perforated and solid fins attached on a flat surface are studied numerically. Higher performances for perforated fins are observed and effectiveness increased by increasing number of perforations.…”
