AIR COOLING DEVICE WITHOUT REFRIGERANT

摘要

PURPOSE: A refrigerant-free cooling apparatus is provided to make a cooling apparatus which does not use the refrigerant by providing the frozen air with a blower and a cooling turbine. CONSTITUTION: A refrigerant-free cooling apparatus comprises a blower(200), a cooling turbine(300), a blast pipe(410) and a cold air exhaust pipe(600). The blower sucks and blows the external air. The cooling turbine comprises an intake, a casing and a turbine blade. The intake comprises a hollow portion and a plurality of air blast passages. The intake is fixed in the inner of a casing and an intake distribution space which is communicated with the outside of the air blast passage. The turbine blade is pivotally installed in the hollow of the intake and is rotated with the air sprayed through the air blast passage. The sprayed air is cooled and is discharged to the axial direction. The blast pipe communicates the blower and intake distribution space. The exhaust pipe discharges the air frozen with the cooling turbine.
