Abstract
A concentration cooling apparatus of a refrigerator including housings respectively installed to cold air guide path formed at the side wall of a chilling chamber; a nozzle rotatably supported by the housings and jetting cold air intensively to a high-temperature load occurred region; a nozzle support member arranged with a certain distance from the outer circumference of the nozzle, connected to the nozzle through a connection rod extended from the both sides of the nozzle; an infrared temperature sensor installed on the front of the nozzle; a first driving unit for rotating the nozzle in the circumferential direction by rotating the nozzle support member; and a second driving unit for rotating the nozzle up and down by rotating the connection rod rotated according to the rotation direction of the nozzle, thereby discharging cold air intensively onto a high temperature load occurred region, cooling instantly the high temperature load.
