Metal Foam and Finned Metal Foam Heat Sinks for Electronics Cooling in Buoyancy-Induced Convection
In this paper, we present our recent experimental results on buoyancy-induced convection in aluminum metal foams of different pore densities [corresponding to 5, 10, 20, and 40 pores per in. (PPI)] and porosities (0.89–0.96). The results show that compared to a heated surface, the heat transfer coefficients in these heat sinks are five to six times higher. However, when compared to commercially...
متن کاملThermal-Hydraulic Performance of Metal Foam Heat Exchangers
Due to their large surface-area-to-volume ratio and tortuous structure, metal foams hold promise for heat transfer applications. Both of these factors increase the heat transfer by enhancing the mixing and surface area. The main disadvantage associated with their thermal-hydraulic performance is relatively higher pressure drop, resulting in larger pumping power requirements if they are used in ...
متن کاملA synthesis of fluid and thermal transport models for metal foam heat exchangers
Metal foam heat exchangers have considerable advantages in thermal management and heat recovery over several commercially available heat exchangers. In this work, the effects of micro structural metal foam properties, such as porosity, pore and fiber diameters, tortuosity, pore density, and relative density, on the heat exchanger performance are discussed. The pertinent correlations in the lite...
متن کاملCeramics and ceramic matrix composites for heat exchangers in advanced thermal systems-A review
In air-conditioning and energy-recovery applications, heat exchangers are very important to the overall efficiency, cost, and size of the system. Current heat exchanger designs rely heavily on fin-and-tube or plate heat exchanger designs, often constructed using copper and aluminum. Recent developments in material sciencedin particular, advances in ceramics and ceramic matrix compositesdopen op...
متن کاملFabrication, Assembly, and Testing of Metal-based Microchannel Heat Exchangers
Microsystem technologies are believed to be an important part of the technological foundation upon which the world can continue to improve the standard of living in the twenty-first century. Microelectromechanical systems (MEMS) have been studied intensely for over two decades. Si-based MEMS, fabricated by surface and bulk micromachining techniques derived from IC processing technology, dominat...
