PURPOSE: An ice-making unit is provided to make crystal-like ice by circulating water in a tray and contacting the water with a cooling protrusion. CONSTITUTION: An ice-making unit includes a water dish, a cooling plate, and a water circulator(30). The water is put in the water dish. The cooling plate includes a evaporation tube in a refrigerating system. A cooling projection, which is dipped in the water, is installed in the lower side of the cooling plate. The water circulator rotates the water in the circumference of the projection and vibrates it. The water circulator includes a water pipe(31) and a pumping motor. The water pipe comprises a discharge port formed in one side of the water dish and a water intake port formed in the other side of the water dish. The pumping motor is installed between an water exit and an absorbing hole. The water contacting the cooling projection is circulated in the water dish while the ice-making unit executes an ice-making process through a refrigerator system.
