Abstract:	This research studies the heat transfer characteristic of an unsteady close-contact melting on a flat plate in the cool-thermal discharge systems with external recycle, develops the mathematical model theoretically to simulate the conduction-convection heat-transfer phenomena, and calculates the theoretical prediction of the outlet chilled air temperature by solving the energy balance associated with integral boundary-layer analysis. It is found that the recycle effect can enhance the average Nusselt numbers and heat-transfer efficiency improvement effectively. Three numerical examples of inlet ambient air temperature are illustrated to compute the chilled air temperature, average Nusselt numbers and heat-transfer efficiency with three specified volumetric flow rate and three traversed length of the ambient inlet air as parameters.
