Ice making apparatus and refrigerator having the same

摘要

An ice making apparatus capable of reducing an ice making time be rapid cooling of an ice making tray thereof while guaranteeing the making of transparent ice and a refrigerating having the ice making apparatus. The ice making apparatus includes the ice making tray to freeze water filled therein so as to make ice, and a cold air guiding device to guide cold air to a lower surface of the ice making tray. The cold air guiding device includes a cold air guiding plate installed below the ice making tray to be spaced apart from the lower surface of the ice making tray, and a plurality of protrusions provided at an upper surface of the cold air guiding plate to guide the cold air flowing along the upper surface of the cold air guiding plate in a direction toward the lower surface of the ice making tray.
