Abstract

The cooling apparatus includes: a compressor (130) configured to generate compressed air; first and second vortex tubes (160, 170) configured to generate cold air based on the compressed air generated from the compressor; a first valve (140) installed between the compressor and the first vortex tube; a second valve (150) installed between the compressor and the second vortex tube; first and second temperature sensors (121, 122) installed in the power converter and configured to measure the internal temperature of the power converter; and a control unit (180) configured to determine whether or not the first and second vortex tubes supply the cold air into a power converter (110), based on first and second temperatures respectively measured by the first and second temperature sensors, and to transmit a valve open signal or a valve close signal to the first and second valves based on a result of the determination.
