Numerical investigation of heat transfer performance for rectangular, elliptical, and airfoil shaped pin fin heatsinks through the novel combination of perforation and bulge inserts

Experimental investigation of forced convection heat transfer for different models of PPFHS heatsinks with different fin-pin spacing

“…The results show that the performance of the 3D-printed heatsink is significantly superior to the classic design which can be used in future designing of heatsinks. Haque et al [ 23 ] studied and investigated the thermal heat transfer of several types of heatsink designs. These designs included rectangular, elliptical, and airfoil-shaped pins.…”

Experimental and numerical studies of the effect of perforation configuration on heat transfer enhancement of pin fins heat sink

“…[1][2][3][4][5] Furthermore, diverse studies on pin fin configurations have already been conducted in prior research. [6][7][8][9][10] Haque et al 21 explored how the hydrothermal performance of twisted and grooved-shaped pin fin heat sinks (PFHS) is influenced by the shape and alignment of the perforations. The findings indicated that the heat transmission performance of the grooved-shaped perforated PFHS was 27% enhanced better than the base case, which lacked perforations and featured twisted-shaped pin fins.…”

“…The current study was conducted for heat sinks commonly employed in various industrial applications, including but not limited to the cooling of small electronic components, central processing units (CPUs) in personal computers and data centers, electronic boards, advanced electronic chips, electrical devices such as computer power supplies and substation transformers, the aerospace sector, and the cooling of fuel elements in nuclear reactors (Upalkar et al, 2020). [29][30][31][32][33] In the existing literature on heat sink optimization through perforations, the majority of studies have concentrated on single types of perforations (Zohora et al, 2023), 2,8,11,34,35 leading to a fragmented understanding of circular perforated cylindrical fin pin heat sink performance.…”

“…Turbulent flow characteristics predicted using the Navier-Stokes equations and the k-ε turbulence model, particularly within the context of Reynolds-averaged Navier-Stokes (RANS), are of specific interest. 8,34,36 The studies involve employing numerical analysis across a range of inlet velocities, varying from 0.5 to 2.5 m/s (Sundaram & Venkatesan, 2015). 37,38 Furthermore, parametric investigations are carried out to analyze the impact of different perforation combinations on the PFHS and Reynold number on Nusselt number, friction factor, thermal resistance, and overall enhancement ratio (hydrothermal performance).…”

Numerical simulation of dust particle deposition and heat transfer in fin-plate radiators

“…Since the power of modern electronic devices increases every year, scientists in this field are conducting research aimed at increasing the rate of heat transfer by changing the shape and size of the plates and pins [8,9], perforation [10], changing the orientation of the plates and pins relative to the oncoming flow air [11], etc. Haque et al [12] conducted numerical studies of heat transfer in a radiator with pin fins of rectangular, elliptical and teardrop shapes with perforations. Research results have shown that the hydrothermal efficiency factor (HTPF) of a radiator with elliptical fins is 9-46% higher than the HTPF of radiators of other configurations.…”
