ABSTRACT:
A cooling apparatus for use in a cooling system is disclosed. The cooling apparatus comprises an evaporator having a conductive pipe which is wound spirally, and a blowing device for blowing air toward the evaporator. A plurality of fins for heat exchange are disposed on the outer surface of the conductive pipe. The blowing device has a blowing motor, a fan being rotated by the blowing motor, and a fan moving device for reciprocating the fan along the blowing direction during the rotation of the fan. Since the cool air generated from the evaporator moves with being rotated by the spirally wound conductive pipe, the air flow becomes complex and thus the heat exchange efficiency becomes high. Also, since the fan is reciprocated along the blowing direction, the blowing power is varied repeatedly and the heat exchange efficiency becomes even higher.
