“…In Ref. [71], the fluid flow and heat transfer performances of aluminum foam heat sink with pin fins (AFPF heat sink) were experimentally and numerically investigated. Aluminum foams with the porosity of 0.88 and pore densities of 10 PPI and 20 PPI were incorporated into the pin fin array channel to produce the test sections.…”

“…3.6 Metal Foam Heat Sink Optimization. Numerous studies have focused on the fluid flow and heat transfer characteristics of various metal foam heat sink designs, covering fully and partially filled metal foam heat sink [84], nonuniform metal foam heat sink [95], and finned metal foam heat sink [71]. It should be pointed out that these designs were not optimized, so further performance improvement in the heat dissipation rate, along with reducing pumping power consumption could be expected.…”

High porosity metal foams offer large surface area per unit volume and have been considered as effective candidates for convection heat transfer enhancement, with applications as heat sinks in electronics cooling. In this paper, the research progress in thermo-hydraulic performance characterization of metal foams and their application as heat sinks for electronics cooling are reviewed. We focus on natural convection, forced convection, flow boiling, and solid/liquid phase change using phase change materials (PCMs). Under these heat transfer conditions, the effects of various parameters influencing the performance of metal foam heat sink are discussed. It is concluded that metal foams demonstrate promising capability for heat transfer augmentation, but some key issues still need to be investigated regarding the fundamental mechanisms of heat transfer to enable the development of more efficient and compact heat sinks.

Metallic porous material plays an irreplaceable role in weight reduction, heat dissipation, catalyst, and other industrial applications. The customized, large production and environment-friendly fabrication of porous metallic material are becoming increasingly important. Moreover, the selection of matrix material, control of porosity, and foaming parameters are critical for determining the quality of porous metallic material and product. As the porous metallic material is often used as the structural and/or functional component, its mechanical, heat dissipation, corrosion resistance and other properties need to be evaluated before industrial application. This review provides an overview of the fabrication techniques, characteristics, and applications of porous metallic materials. Additionally, current industrial applications and potential future areas are discussed.

“…The HS cooling fluids and the cooling methods differ in different devices: some are cooled via natural convection [ 23 , 24 , 25 ], and some via forced convection [ 26 , 27 , 28 , 29 ]. Fluids such as air [ 30 , 31 ], water [ 32 , 33 , 34 , 35 ], oil [ 36 , 37 ], and, most importantly, NFs are utilized as the working fluid in MHSs [ 38 ]. In one paper [ 39 ], Leela Vinodhan and Rajan designed a new MHS and examined its thermal efficiency.…”

In this paper, two novel micro heat sinks (MHSs) were designed and subjected to thermal analysis using a numerical method. The fluid used was Boehmite alumina–water nanofluid (NFs) with high volume fractions (VOFs). Studies were conducted to determine the influence of a variety of nanoparticle (NP) shapes, such as platelet brick, blade, cylinder, and Os. The heatsink (HS) was made of copper, and the NFs entered it through the middle and exited via four outlets at the side of the HS. The finite element method was used to simulate the NFs flow and heat transfer in the HSs. For this purpose, Multi Physics COMSOL software was used. The maximum and middle values of HS temperature (T-MAX and T-Mid), thermal resistance (TH-R), heat transfer coefficient (h), FOM, etc., were studied for different NP shapes, and with Reynolds numbers (Re) of 300, 1000, and 1700, and VOFs of 0, 3, and 6%. One of the important outcomes of this work was the better thermal efficiency of the HS with rectangular fins. Moreover, it was discovered that a rise in Re increased the heat transfer. In general, adding NPs with high VOFs to MHSs is not appropriate in terms of heat. The Os shape was the best NP shape, and the platelet shape was the worst NP shape for high NPVOF. When NPs were added to an MHS, the temperature of the MHS dropped by an average of 2.8 or 2.19 K, depending on the form of the pin-fins contained inside the MHS (circular or square). The addition of NPs in the MHS with circular and square pin-fins enhanced the pressure drop by 13.5% and 13.3%, respectively, when the Re = 1700.
