Experimental Investigation of Water Flow Heat Transfer in Metal Foams

Abstract:

This paper aims at finding the best pore density and porosity of metal foams for heat transfer, as well as the most proper operating conditions. A circulating water cooling system were designed which include micro-channel heat sink, heat exchanger, micro-pump, rot meter, electric heating rods, and conversion fans for the experiment. The comparison was made between different metal foam samples in terms of flow rate and equilibrium temperature of heating boundary. The results presented that a relatively low temperature can be achieved when flow rate is large, but at the same time the pressure drop increased. The excellent heat dissipation performance of metal foams has a close relationship with its specific surface area.
