Freezing compartment air flow system of refrigerator

A refrigerator comprising:

• a freezing compartment provided with a base plate having a chilled air passageway for exhausting a chilled air, said freezing compartment including a rear wall having a main-inlet for said chilled air directed by a fan to flow and a plurality of sub-inlets for said chilled air to flow, said subinlets being smaller than said main-inlet and being formed under said main-inlet;
• a refrigerating compartment positioned under said freezing compartment;
• a partition for separating said freezing compartment and said refrigerating compartment and for forming a first air outlet between said base plate and said partition for exhausting said chilled air from said freezing compartment and a second air outlet between said refrigerating compartment and said partition for exhausting said chilled air from said refrigerating compartment,
• said base plate including an upper plate having a plurality of third outlets, and a lower plate having a plurality of protrusions for supporting said upper plate, and for forming said chilled air passageway with said upper plate, said lower plate being comprised of an insulating material;
• an evaporator installed between said freezing compartment and an outer wall for cooling air and removing humidity contained in the air to generate said chilled air;
• and
• a fan for directing the flow of said chilled air into said freezing compartment and said refrigerating compartment,
• wherein a main air duct for providing a passage for said chilled air to flow into said refrigerating compartment by said fan is formed between said evaporator and said outer wall, a first air duct for the flow of said chilled air exhausted from said freezing compartment to said evaporator is formed between said freezing compartment and said partition, a second air duct for the flow of said chilled air exhausted from said refrigerating compartment to said evaporator is formed between said partition and said refrigerating compartment, and a third air duct where said chilled air from said first and second air ducts is mixed is formed between said first and second air ducts, and said evaporator.
