Experimental work was carried out to obtain information concerned with the optimum conditions for the melting of frost on a heat exchanger. An ice particles layer representing frost was melted on a heated base with fins consisting of copper plates. The size ratio of the length between the fins to the height of a fin L/H ranged from 0.33 to 1.33. It was demonstrated that the heat flux supplied to melt the ice particles layer produces a large heat loss compared with the melting of the ice plate. This behavior is mainly attributable to the fact that the ice particles layer is a porous media. The ratio of the net heat flux for the melting to the supplied heat flux Q_m/Q_t is dependent on the density of ice particles layer, the supplied heat flux, the environmental temperature (initial temperature of the ice particle layer) and the size ratio of the fin.
