Summary:

Abstract: Electrification is one of the megatrends across theindustries, like electric vehicles, more electric aircraft,electric vehicles et cetera which needs advancement in power electronicscomponent technology. As technology advances in miniaturization ofpower electronics, thermal-management issues threaten to limit theperformance of these devices. These may force designers to deratethe device performance and ultimately these compromise in designmay increase the size, weight of the application. One of thetechnologies capable of accomplishing these goals employs a classof materials know as metal foam. Metal foams are lightweightcellular materials inspired by nature. The main application ofmetal foams can be grouped into structural and functional and arebased on several excellent properties of the material. Structuralapplications take advantage of the light-weight and specificmechanical properties of metal foam. Functional applications arebased on a special functionality, id est a large open area incombination with very good thermal conductivity for heatdissipation. This paper reports the results of an experimentalinvestigation on the heat transfer performance of metal foam andsolid metal under forces and natural convection. Experiments havebeen conducted with aluminum metal foams in two different poredensities and solid aluminum using air as fluid medium. Poredensities of metal foam used for experiments are 10PPI and 20PPI.Experiments are performed for two different flow rates using twospeed fan and two power rating (heat load) using heating coil assource. Thermocouple were placed at heat source side and onopposite side of samples to effectively measure the surfacetemperature. Surface temperature of samples are measured andcompared for all the samples. Experiment results shows that samethermal response can be achieved with 50% smaller size of foam ascompared to solid aluminum along with weight benefit (~5x) underforced convection.
