PURPOSE: A cooling air circulating apparatus for refrigerator is provided to achieve an improved cooling efficiency by allowing the cooling air to be widely discharged and recirculated over the refrigerating compartment. CONSTITUTION: An apparatus comprises a duct base(20) having a plurality of cooling air discharge channels(20a) for ingress of cooling air transferred from an evaporator, a circulating cooling air suction channel(20b) separated from the cooling air discharge channels, and a plurality of circulating cooling air discharge channels(20c) connected to the cooling air suction channel; a duct cover covering the duct base, and which has a plurality of cooling air discharge ports formed at the position connected to the cooling air discharge channels, a cooling air suction port formed at the position connected to the cooling air suction channel, and a plurality of circulating cooling air discharge ports formed at the position connected to the circulating cooling air discharge channels; a damper unit(30) for adjusting the amount of cooling air flowing into the cooling air discharge channels of the duct base; and a ventilating fan(40) disposed within the cooling air suction channel of the duct base and which re-sucks, through the circulating cooling air suction channel of the duct base, the cooling air discharged through the cooling air discharge ports of the duct cover. |
