PROBLEM TO BE SOLVED: To provide a cooling clothing whose structure is simple, electricity consumption is low and by which a wearer can live comfortably even in high- temperature environment such as outdoor in the midsummer. SOLUTION: The body of this cooling clothing is provided with two cooling sheets 20 respectively in the front and the back and four cooling sheets 20 in total. The cooling sheet 20 is composed of a lower sheet 21, an upper sheet 22, a fan 23, a sponge 24 made of polyvinyl alcohol, an upper cloth 25, or the like. Air sucked by the fan 23 flows through a ventilating passage between the sheets 21 and 22 and is exhausted from an outlet 22d. Water fed on the right side of the lower sheet 21 contacts closely with air flowing from the upper part to the lower part in the ventilating passage to vaporize incessantly while the water diffuses on the surface of the sheet 21. At this very moment, the water eliminates heat of vaporization from surroundings, and the lower sheet 21 is cooled by the vaporization of water. Heat effused from the body of a wearer contacting closely with the sheet 21 is almost absorbed in the whole of the sheet 21, and the body is effectively cooled. |
