What is claimed is: 1. A refrigerator comprising a refrigerator body having a freezing compartment defined therein, an evaporator mounted at a rear part of the freezing compartment, a guide duct mounted in front of the evaporator to disperse and supply cool air to upper and lower parts of the freezing compartment, and an ice making device including an ice making tray to receive water to be frozen, wherein the ice making tray has ice making grooves opened at the upper sides thereof to receive water and a cool air flow channel disposed below the ice making grooves and along which cool air flows, the ice making tray is rotatably connected to an ice separating motor to generate a rotating force such that the ice making tray is turned upside down, the ice making device further includes a cool air guide pipe selectively connectable to the cool air flow channel such that the cool air is supplied to the cool air flow channel only when the ice making tray is positioned with the ice making grooves upward, and the ice making tray includes an ice making part having the ice making grooves and a cool air guide part to cover a lower surface of the ice making part while being located a predetermined distance from the lower surface of the ice making part such that the cool air flow channel is defined between the ice making part and the cool air guide part, the cool air guide part having an inlet port, formed at one side thereof, to which a cool air guide pipe is connected such that the cool air is supplied to the cool air flow channel through the inlet port, and an outlet port formed, at the other side thereof, through which the cool air is discharged. 2. The refrigerator according to claim 1, wherein the cool air guide pipe is made of an elastically deformable material such that, when the ice making tray is positioned with the ice making grooves upward, a tip end of the cool air guide pipe protrudes into the cool air flow channel through the inlet port. 3. The refrigerator according to claim 2, wherein the tip end of the cool air guide pipe, which is connected to the cool air flow channel, is formed in a zigzag shape such that the tip end of the cool air guide pipe is readily elastically deformed. 4. The refrigerator according to claim 1, wherein the ice making tray has a plurality of heat exchange fins formed at the lower surface of the ice making part, such that the heat exchange fins protrude into the cool air flow channel, to improve an efficiency of heat exchange between the ice making part and the cool air. 5. The refrigerator according to claim 1, wherein the ice making tray has a plurality of whirlpool induction fins protruding from the lower surface of the ice making part into the cool air flow channel and having a width in a direction perpendicular to a flow direction of the cool air to generate whirlpools at an upper part of the cool air flow channel. 6. The refrigerator according to claim 2, wherein the ice making device further includes an injection nozzle extending from a guide duct to an inlet port side and having an inner diameter gradually decreased to increase a flow speed of the cool air passing therethrough, the cool air guide pipe being connected to a tip end of the injection nozzle. 7. The refrigerator according to claim 1, wherein the ice making part and the cool air guide part are made of an elastically deformable material such that the ice making part and the cool air guide part are twisted, when the ice making part and the cool air guide part are rotated by the ice separating motor, accomplishing the ice separation. 8. The refrigerator according to claim 7, wherein the cool air guide part is made of a material that is more easily elastically deformed than the ice making part. 9. The refrigerator according to claim 1, further including an ice storage box opened at an upper side thereof to store ice falling from the ice making device. 10. The refrigerator according to claim 9, further including a door hingedly coupled to one side of the refrigerator body to open and close the freezing compartment and a discharge guide duct, which communicates with an interior of the freezing compartment to guide discharge of ice such that a user may remove the ice made by the ice making device without opening the door. 11. The refrigerator according to claim 10, further including an ice feeding unit rotatably mounted in the ice storage box to feed the ice to a discharge guide duct side, wherein the ice feeding unit includes a feeding wing formed in a spiral shape and rotatable so as to feed the ice to a discharge guide duct side and a feeding motor to generate a rotating force to rotate the feeding wing. 12. The refrigerator according to claim 11, further including an ice discharge unit, depressed inward at a front part of the door, to receive the ice discharged through the discharge guide duct. 13. The refrigerator according to claim 9, further including an ice amount detecting lever to detect an amount of ice received in the ice storage box to turn on or off operation of the ice making device. 14. A refrigerator comprising a refrigerator body having a freezing compartment defined therein, an evaporator mounted at a rear part of the freezing compartment, a guide duct mounted in front of the evaporator to disperse and supply cool air to upper and lower parts of the freezing compartment, and an ice making device including an ice making tray to receive water to be used to make ice, wherein the ice making device further includes an upper discharge port, through which cool air guided along the a duct is discharged to an upper part of the ice making tray, a lower discharge port, through which cool air guided along the guide duct is discharged to a lower part of the ice making tray, and a damping unit mounted in the guide duct to selectively restrict a supply of the cool air to the upper discharge port. 15. The refrigerator according to claim 14, wherein the upper discharge port and the lower discharge port are provided at tip ends of an upper nozzle and a lower nozzle extending from the ice making tray to an upper part and the lower part of the ice making tray, respectively. 16. The refrigerator according to claim 14, wherein the damping unit includes a damper rotatably mounted in the guide duct to selectively restrict the supply of the cool air to the upper discharge port. 17. The refrigerator according to claim 16, wherein the damping unit further includes a rod movable upward, by a solenoid, to rotate the damper in one direction, and an elastic member to elastically support the rod and restore the rod to an original position.
