Abstract

Nowadays, with the advancement of technology, high-speed electronic instruments with small sizes are required. Regarding the low density of Metal Foams, they are recommended for many applications in order to energy absorption and Heat transfer purposes. In this paper, the Heat sinks made of metal-foams are simulated and the results are compared with simple finned Heat sinks. In the Heat sinks that made from aluminum foams with porosity value of 95. 6%, the amount of Heat transfer coefficient of displacement increases up to 31. 127%. In another part of the dissertation, a finned Heat sink, which metal-foam is placed between its fins is modeled. Obtained results show that, the Nusselt number in the Heat sinks that made of aluminum foam with porosity of 95. 6%, in the finned mode could increase up to two times. Finally, the effects of parameters such as the amount of mass discharge, the Heat sink height and the amount of porosity of Heat sink foam on the amount of Heat transfer through Heat sinks is determined at the end part.
