Air cooling device

摘要

An air cooling device including a first water spray device, an air cooling part including a filler wherein cooling water sprayed from the first water spray device is brought into direct contact with intake air so that the intake air is cooled by the sprayed water through heat exchange therebetween on the surface of the filler, a first water reservoir that receives and reserves the water dropped from the filler and a cooling tower for rapidly cooling water to be sprayed in the air cooling part to a steady state condition prior to starting of an electrical apparata coupled to the air cooling device and to be cooled thereby. In the cooling tower, water from the first reservoir is sprayed into a second filler and thereby evaporatively cooled. The cooled water is collected in a second water reservoir and circulated therefrom to the first water spray device by means of a pump.
