Cooling air blowing apparatus of refrigerator

A cooling air blowing apparatus of a refrigerator, comprising:

• a driving motor fixed to a motor mount formed at a rear side of a freezing chamber;
• a blowing fan mounted on a rotational shaft of the driving motor and configured to blow cooling air in an axial direction and in a radial direction, while being rotated as the driving motor is driven;
• and
• a shroud positioned in a circumferential direction of the blowing fan to minimize recirculation of cooling air into a suction chamber, wherein the blowing fan comprises:
• a hub fixed on the rotational shaft of the driving motor,
• axial flow blades formed with a curved face having a certain radius of curvature formed at regular intervals along a circumference of the hub and configured to blow cooling air in an axial direction, and
• turbo blades that extend between a blade tip and a trailing edge along the curvature of the axial flow blade, extending beyond an outer diameter of the axial flow blades and configured to blow the cooling air in a radial direction.
